Abstract

Penggunaan bahan alami sebagai imbuhan pakan atau minuman dalam peternakan modern terus dikembangkan untuk meningkatkan performa ternak. Penelitian ini bertujuan untuk mengevaluasi efektivitas infusa daun herbal terhadap bobot akhir, persentase karkas, dan kesehatan organ dalam ayam broiler. Sebanyak 200 ekor DOC broiler strain Mabar tanpa pemisahan jenis kelamin digunakan dalam rancangan acak lengkap (RAL) dengan empat perlakuan dan lima ulangan, masing-masing ulangan terdiri dari sepuluh ekor ayam. Perlakuan terdiri atas: P0 (kontrol, tanpa infusa), P1 (infusa daun mengkudu 40 ml/l air minum), P2 (infusa daun pandan 40 ml/l air minum), dan P3 (infusa daun pepaya 40 ml/l air minum). Peubah yang diamati meliputi bobot akhir, persentase karkas, persentase lemak abdominal, persentase bobot hati, dan persentase bobot jantung. Hasil penelitian menunjukkan bahwa infusa daun herbal memberikan pengaruh sangat nyata (p<0,01) terhadap bobot akhir, dimana perlakuan P3 menghasilkan bobot tertinggi (1,63±0,06 kg), serta berpengaruh nyata (p<0,05) terhadap persentase karkas, dengan perlakuan P3 menghasilkan nilai tertinggi (67,90±2,13). Selain itu, infusa juga berpengaruh nyata (p<0,05) terhadap penurunan lemak abdominal, dengan nilai terendah pada perlakuan P3 (1,83±0,05). Persentase hati menujukkan perbedaan sangat nyata (p<0,01) dengan nilai terendah pada perlakuan P3 (1,84±0,06), sedangkan persentase jantung tidak berbeda nyata antar perlakuan (P>0,05) dengan kisaran 0,60-0,67%. Disimpulkan bahwa pemberian infusa daun herbal, khususnya daun pepaya berpotensi meningkatkan performa pertumbuhan dan menurunkan lemak abdominal tanpa mengganggu kualitas karkas dan kesehatan jantung ayam broiler. ABSTRACT The use of natural ingredients as feed or drinking water additives in modern poultry farming continues to be developed to improve livestock performance. This study aimed to evaluate the effectiveness of herbal leaf infusions on live weight, carcass percentage, and internal organ health in broiler chickens. A total of 200 unsexed DOC broilers of the Mabar strain were used in a completely randomized design (CRD) with four treatments and five replications, with each replication consisting of ten birds. The treatments were as follows: P0 (control, without infusion), P1 (noni leaf infusion at 40 ml/L of drinking water), P2 (pandan leaf infusion at 40 ml/L), and P3 (papaya leaf infusion at 40 ml/L). The observed variables included final body weight, carcass percentage, abdominal fat percentage, liver weight percentage, and heart weight percentage. The results showed that herbal leaf infusions had a highly significant effect (p<0.01) on live weight, with treatment P3 yielding the highest weight (1.63 ± 0.06 kg), and a significant effect (p<0.05) on carcass percentage, with treatment P3 showing the highest value (67.90 ± 2.13%). In addition, the infusions significantly reduced abdominal fat (p<0.05), with the lowest value observed in treatment P3 (1.83 ± 0.05%). Liver percentage showed a highly significant difference (p<0.01), with the lowest value also in treatment P3 (1.84 ± 0.06%), while heart percentage showed no significant difference among treatments (P>0.05), ranging from 0.60 to 0.67%. It is concluded that administering herbal leaf infusions, particularly papaya leaf infusion, has the potential to enhance growth performance and reduce abdominal fat without negatively affecting carcass quality and heart health in broiler chickens

Abstract

Limbah buah durian mengandung nutrisi dan senyawa bioaktif seperti tanin, alkaloid, triterpenoid, flavonoid, serta β-karoten yang berpotensi meningkatkan kualitas kuning telur. Penelitian ini bertujuan mengetahui pengaruh penambahan limbah durian yang difermentasi Pleurotus ostreatus dalam ransum ayam petelur terhadap kualitas kuning telur. Penelitian dilakukan secara eksperimental menggunakan Rancangan Acak Lengkap dengan lima perlakuan yaitu P0 (ransum tanpa limbah buah durian fermentasi; P1 (ransum dengan 5% limbah buah durian fermentasi); P2 (ransum dengan 10% limbah buah durian fermentasi); P3 (ransum dengan 15% limbah buah durian fermentasi); dan P4 (ransum dengan 20% limbah buah durian fermentasi), dimana masing-masing dengan empat ulangan. Peubah yang diamati meliputi bobot, warna, dan kolesterol kuning telur. Hasil penelitian menunjukkan bobot, warna maupun kolesterol kuning telur perlakuan P0 (ransum tanpa limbah buah durian fermentasi) berbeda nyata (p<0,05) dibanding ransum dengan limbah buah durian fermentasi. Penambahan hingga 20% limbah durian fermentasi meningkatkan bobot dan intensitas warna kuning telur, sedangkan penambahan 5% efektif menurunkan kadar kolesterol. Penelitian ini menunjukkan potensi limbah durian fermentasi sebagai alternatif bahan pakan fungsional untuk meningkatkan kualitas telur ayam. ABSTRACT Durian waste contains nutrients and bioactive compounds, including tannins, alkaloids, triterpenoids, flavonoids, and β-carotene, which have the potential to enhance egg yolk quality. This study aimed to investigate the effect of adding durian waste fermented by Pleurotus ostreatus to laying hen rations on egg yolk quality. The research was conducted experimentally using a Completely Randomized Design with five treatments, namely P0 (ration without fermented durian fruit waste; P1 (ration with 5% fermented durian fruit waste); P2 (ration with 10% fermented durian fruit waste); P3 (ration with 15% fermented durian fruit waste); and P4 (ration with 20% fermented durian fruit waste), each with four replications. The variables observed included egg yolk weight, egg yolk color, and egg yolk cholesterol. The results showed that the weight, color, and cholesterol of the egg yolk of the P0 treatment (ration without fermented durian fruit waste) were significantly different (p<0.05) compared to the ration with fermented durian fruit waste. The addition of up to 20% fermented durian waste increased the weight and intensity of the egg yolk color, while the addition of 5% was effective in reducing cholesterol levels. This study demonstrates the potential of fermented durian waste as an alternative functional feed ingredient to improve egg quality in laying hens.

Abstract

Industri pengolahan ikan patin di Indonesia menyisakan limbah yang dapat dijadikan sebagai pakan suplemen ayam broiler, tetapi diperlukan fermentasi untuk menurunkan kandungan lemaknya dan mikroenkapsulasi untuk melindungi kandungan nutriennya dari kerusakan oksidasi. Penelitian ini bertujuan untuk mengetahui adanya pengaruh penambahan mikrokapsul ekstrak limbah ikan patin fermentasi (MELIPF) dan mendapatkan level penambahan MELIPF yang menghasilkan nilai kecernaan Bahan Kering (KcBK), Bahan Organik (KcBO), dan protein (KcP) ransum tertinggi ayam broiler. Sebanyak 80 ekor ayam broiler strain Cobb500 diberi ransum dengan perlakuan penambahan MELIPF 0%, 0,5%, 1%, 1,5%, dan 2%. Sampel ransum dan feses dianalisis kandungan BK, BO, dan proteinnya serta lignin sebagai indikator. Data yang diperoleh dianalisis ragam menggunakan rancangan acak lengkap dilanjut dengan uji beda nyata terkecil untuk mengetahui perbedaan antar perlakuan. Hasil penelitian menunjukkan bahwa penambahan MELIPF berpengaruh terhadap nilai KcBK, KcBO, dan KcP ransum ayam broiler. Penambahan MELIPF 0,5%, 1%, dan 2% berpengaruh nyata (p<0,05) lebih rendah dibandingkan dengan 0% MELIPF pada KcBK dan KcBO, sedangkan penambahan 2% MELIPF berpengaruh nyata (p<00,05) lebih rendah dibandingkan dengan 0% MELIPF pada KcP. Penambahan 1,5% MELIPF menghasilkan nilai KcBK, KcBO, dan KcP ransum ayam broiler tertinggi. ABSTRACT The catfish processing industry in Indonesia generates waste that can be used as supplementary feed for broiler chickens, but it requires fermentation to reduce fat and microencapsulation to protect nutrients from oxidation. This study aimed to determine the effect of additional fermented catfish waste extract microcapsules (FCWEM) and obtain the optimal level of FCWEM addition that produces the highest digestibility ​​of Dry Matter (DM), Organic Matter (OM), and protein in broiler chicken rations. 80 Cobb500 strain broiler chickens were given rations with FCWEM addition treatments of 0%, 0.5%, 1%, 1.5%, and 2%. Ration and feces samples were analyzed for their DM, OM, protein, and indicator lignin. Data obtained were analyzed for variance with a completely randomized design, followed by the least significant difference test to determine differences between treatments. Results showed the addition of FCWEM affected the digestibility of DM, OM, and protein in broiler chicken rations. The addition of FCWEM 0.5%, 1%, and 2% had a significantly lower effect (p<0.05) compared to 0% FCWEM on digestibility DM and OM, while the addition of 2% FCWEM had a significantly lower effect (p<0.05) compared to 0% MELIPF on digestibility protein. The addition of 1.5% FCWEM produced the highest digestibility ​​of DM, OM, and protein in broiler chicken rations.

Abstract

Penggunaan herbsprobiotic, kombinasi senyawa bioaktif herbal (jahe, kunyit, temulawak, temu ireng, dan kencur) dan mikroorganisme probiotik (Bacillus subtilis, Bifidobacterium longum, Lactobacillus bulgaricus, dan Saccharomyces cerevisiae), diteliti sebagai alternatif pemacu pertumbuhan yang ramah lingkungan. Penelitian ini bertujuan mengevaluasi pengaruh herbsprobiotic dalam air minum terhadap profil darah puyuh sebagai indikator kesehatan fisiologis. Empat perlakuan diberikan: P0 (kontrol), P1 (0,5 ml/l), P2 (1 ml/l), dan P3 (1,5 ml/l). Peubah yang diamati adalah konsumsi pakan, konsumsi minum, bobot badan, umur pertama kali bertelur, produksi telur dan bobot telur, ketebalan kerabang, jumlah eritrosit, jumlah leukosit dan rasio heterophyl/limposit (H/L). Data yang diperoleh dianalisis menggunakan analisis ragam dan dilanjutkan dengan uji beda nyata jujur. Hasil menunjukkan herbsprobiotic berpengaruh nyata terhadap peningkatan eritrosit dan hemoglobin. Peningkatan jumlah eritrosit terjadi dari 2,72 ± 0,01 x10⁶/mm³ (P0) menjadi 2,85 ± 0,06 x10⁶/mm³ (P3), dan kadar hemoglobin meningkat dari 8,96 ± 0,04 g/dL (P0) menjadi 12,49 ± 0,02 g/dL (P3). Jumlah leukosit dan rasio heterofil/limfosit (H/L) tidak menunjukkan perbedaan nyata antar perlakuan, dengan kisaran leukosit 14,92 ± 0,94 – 16,88 ± 0,77 ribu/mm³ dan rasio H/L 0,54 ± 0,18 – 0,61 ± 0,03. Peningkatan eritropoiesis diduga terjadi melalui stimulasi sumsum tulang oleh mikroba probiotik dan senyawa aktif herbal. Dengan demikian, suplementasi herbsprobiotic melalui air minum efektif meningkatkan parameter hematologis tertentu dan mendukung kesehatan puyuh. ABSTRACT The use of herbal probiotics, a combination of bioactive herbal ingredients (ginger, turmeric, temulawak, temu ireng and kencur) and probiotic microorganisms (Bacillus subtilis, Bifidobacterium longum, Lactobacillus bulgaricus and Saccharomyces cerevisiae), was investigated as an environmentally friendly alternative for growth promotion. This study aimed to evaluate the effect of herbal probiotics in drinking water on the blood profile of quail as an indicator of physiological health. Four treatments were given: P0 (control), P1 (0.5 ml/l), P2 (1 ml/l) and P3 (1.5 ml/l). The observed variables are feed consumption, water intake, body weight, age at first laying, egg production and egg weight, shell thickness, erythrocyte count, leukocyte count, and the Heterophil/Lymphocyte ratio. The obtained data were analyzed using analysis of variance and followed by the honest significant difference test. The results showed that herbal probiotic had a significant effect (P<0.05) on the increase of erythrocytes and hemoglobin. Erythrocyte count increased from 2.72 ± 0.01 x10⁶/mm³ (P0) to 2.85 ± 0.06 x10⁶/mm³ (P3), and hemoglobin level increased from 8.96 ± 0.04 g/dL (P0) to 12.49 ± 0.02 g/dL (P3). The leukocyte count and heterophil/lymphocyte (H/L) ratio showed no significant difference between treatments (P>0.05), with a leukocyte range of 14.92 ± 0.94 - 16.88 ± 0.77 thousand/mm³ and an H/L ratio of 0.54 ± 0.18 - 0.61 ± 0.03. It is thought that the increase in erythropoiesis occurs due to the stimulation of the bone marrow by probiotic microbes and active herbal compounds. Herbal probiotic supplementation via drinking water was thus effective in improving certain hematological parameters and supporting.

Abstract

Mastitis subklinis merupakan penyakit peradangan yang tidak menunjukkan perubahan mencolok pada ambing maupun susu yang dihasilkan dapat berpengaruh negatif terhadap performa produksi sapi perah. Penelitian ini bertujuan untuk mengidentifikasi infeksi mastitis subklinis pada usaha peternakan sapi perah di Desa Babadan Kecamatan Ngancar Kabupaten Kediri. Penelitian menggunakan metode observasi dan screening menggunakan Uji CMT (California Mastitis Test), dimana pengujian dilakukan terhadap total sampel sebanyak 1.087 kuartir (puting) dari populasi 273 ekor sapi perah peranakan Peranakan Friesian Holstein (PFH). Data dianalisis secara deskriptif untuk mengetahui tingkat mastitis subklinis pada peternakan sapi perah. Hasil penelitian menunjukkan sebanyak 416 (38%) sampel susu positif mastitis subklinis dan 671 (62%) sampel susu negatif mastitis. Prevalensi mastitis subklinis yang terdeteksi menggunakan uji CMT pada sapi perah laktasi yang dipelihara secara intensif oleh peternak menunjukkan sejumlah sapi perah mengalami infeksi tanpa menunjukkan gejala yang jelas. Faktor-faktor seperti kebersihan kandang, teknik pemerahan, serta kondisi kesehatan ternak berperan penting dalam tingkat kejadian mastitis subklinis. ABSTRACT Subclinical mastitis is an inflammatory disease that does not show any noticeable changes in the udder or the milk produced, but can negatively impact the production performance of dairy cows. This research aims to identify subclinical mastitis infection in dairy cattle farming in Babadan Village, Ngancar District, Kediri Regency. The research used observation and screening methods using the CMT (California Mastitis Test), where testing was carried out on a total sample of 1,087 quarters from a population of 273 Friesian Holstein crossbred dairy cows. Data were analyzed descriptively to determine the level of subclinical mastitis in dairy farms. The results showed that 416 (38%) milk samples were positive for subclinical mastitis, and 671 (62%) milk samples were negative for mastitis. The prevalence of subclinical mastitis detected using the CMT test in lactating dairy cows intensively raised by farmers showed that a number of dairy cows experienced infection without showing obvious symptoms. Factors such as barn cleanliness, milking techniques, and animal health conditions played a significant role in the incidence of subclinical mastitis.

Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh kombinasi limbah kepala udang dan daun singkong terhadap pertumbuhan dan kandungan protein maggot Black Soldier Fly (BSF). Penelitian menggunakan Rancangan Acak Lengkap (RAL) dengan lima perlakuan: P1 (100% kepala udang), P2 (75% kepala udang + 25% daun singkong), P3 (50%+50%), P4 (25% kepala udang + 75% daun singkong), dan P5 (100% daun singkong). Masing-masing perlakuan dengan tiga ulangan. Variabel yang diamati meliputi berat, panjang, ketebalan maggot, konsumsi pakan, laju pertumbuhan spesifik (SGR), indeks pengurangan limbah (WRI), serta kadar protein. Hasil penelitian menunjukkan bahwa secara deskriptif, nilai rata-rata berat maggot berkisar antara 0,04-0,055 g, panjang antara 10,80-11,73 mm, dan laju pertumbuhan spesifik (SGR) antara 6,13-7,23%. Kadar protein maggot tercatat antara 25,09-27,32%, konsumsi pakan berkisar antara 86-93%, dan efisiensi reduksi limbah (WRI) berada pada rentang 5,28-6,64 g/hari. Berdasarkan hasil analisis ragam, seluruh variabel yang diamati tidak menunjukkan perbedaan yang signifikan antar perlakuan (p > 0,05). Dengan demikian, meskipun terdapat variasi nilai secara deskriptif, perbedaan tersebut tidak dapat dianggap nyata secara statistik dan tidak mencerminkan pengaruh perlakuan yang berbeda terhadap pertumbuhan maggot BSF. Penelitian lanjutan perlu dilakukan dengan jumlah sampel yang lebih besar, serta analisis kandungan nutrisi pakan yang lebih rinci, guna memperoleh hasil yang lebih akurat dan aplikatif. ABSTRACT This study aims to investigate the effect of combining shrimp head waste and cassava leaves on the growth and protein content of Black Soldier Fly (BSF) maggots. The study used a Completely Randomized Design (CRD) with five treatments: P1 (100% shrimp heads), P2 (75% shrimp heads + 25% cassava leaves), P3 (50% + 50%), P4 (25% shrimp heads + 75% cassava leaves), and P5 (100% cassava leaves). Each treatment had three replications. The observed variables included weight, length, thickness of maggots, feed consumption, specific growth rate (SGR), waste reduction index (WRI), and protein content. The results of the study showed that descriptively, the average maggot weight ranged from 0.04-0.055 g, length between 10.80-11.73 mm, and specific growth rate (SGR) between 6.13-7.23%. Maggot protein content was recorded between 25.09-27.32%, feed consumption ranged from 86-93%, and waste reduction efficiency (WRI) was in the range of 5.28-6.64 g/day. Based on the results of the analysis of variance, all observed variables did not show significant differences between treatments (p > 0.05). Thus, although there were variations in descriptive values, these differences cannot be considered statistically significant and do not reflect the effect of different treatments on the growth of BSF maggots. Further research is needed with a larger sample size, as well as a more detailed analysis of feed nutrient content, to obtain more accurate and applicable results.

Abstract

Kurva produksi susu merupakan kurva yang dapat menggambarkan jumlah susu yang dihasilkan oleh sapi perah selama siklus laktasinya. Model kurva yang memiliki tingkat akurasi tinggi antara produksi susu aktual dan pendugaan adalah model kurva Wood dan juga model kurva Ali-Schaeffer. Penelitian ini menganalisis produksi susu di PT. Sumber Citarasa Alam selama periode laktasi pertama dan kedua serta membandingkan akurasi model kurva Wood dan model Ali-Schaeffer dalam merepresentasikan data produksi susu. Standard error (Se) dan koefisien korelasi (r) digunakan sebagai indikator akurasi dalam evaluasi. Hasil penelitian menunjukkan bahwa puncak produksi susu terjadi lebih awal pada periode laktasi kedua dibandingkan dengan periode pertama, yakni pada minggu ke-5 untuk periode kedua dan minggu ke-6 untuk periode pertama. Rata-rata produksi susu pada periode laktasi pertama lebih rendah (13,33 liter) dibandingkan dengan periode laktasi kedua (14,83 liter), setelah itu kurva produksi mengalami penurunan yang berfluktuasi hingga akhir masa laktasi. Model Ali-Schaeffer memberikan pendugaan produksi susu yang lebih akurat pada kedua periode dibandingkan dengan model kurva Wood. Selain itu, nilai Se (0,891 dan 0,955) serta nilai r (0,395 dan 0,429) menunjukkan bahwa model kurva Ali-Schaeffer memiliki korelasi yang lebih kuat dan akurasi yang lebih tinggi dalam merepresentasikan data produksi susu di PT. Sumber Citarasa Alam. ABSTRACT The milk production curve is a model that illustrates the amount of milk produced by dairy cows throughout their lactation cycle. Curve models that exhibit high accuracy between actual milk yield and estimation include the Wood curve model and the Ali-Schaeffer curve model. This study aimed to analyze the milk production of dairy cows at PT. Sumber Citarasa Alam during lactation periods 1 and 2, and to determine which equation between the Wood curve model and the Ali-Schaeffer model most accurately represented the company’s dairy production data. The models were evaluated using Standard Error (SE) and correlation coefficient (r) as accuracy indicators. The study results indicated that dairy cow milk production at PT. Sumber Citarasa Alam reached peak production faster in the second lactation period compared to the first. Peak production occurred in the fifth week for lactation period 2, whereas it occurred in the sixth week for lactation period 1. The average milk production in the first lactation period was lower, amounting to 13.33 liters, while the second lactation period reached 14.83 liters. The production curve then declined fluctuatively until the end of lactation. The Ali-Schaeffer milk production curve model demonstrated a higher estimation accuracy for actual milk production in both lactation periods compared to the Wood curve model. Furthermore, based on the obtained SE values (0.891 and 0.955) and correlation coefficients (0.395 and 0.429), the Ali-Schaeffer model exhibited high correlation and accuracy.

Abstract

Penelitian ini bertujuan untuk mengetahui keragaman bobot badan dan ukuran tubuh, serta menganalisis jarak genetik ayam kampung di Kecamatan Leihitu Barat, Kabupaten Maluku Tengah. Data dikumpulkan melalui observasi dan pengukuran sampel 196 ekor ayam jantan dan betina dewasa dari lima desa yaitu Hatu, Liliboy, Allang, Wakasihu, dan Larike yang mewakili populasi ayam kampung. Variabel morfometrik yang diamati meliputi bobot badan, lingkar dada, panjang sayap, panjang paha, panjang betis, panjang shank, panjang jari ketiga, dan lebar pubis. Analisis statistik deskriptif digunakan untuk menghitung rata-rata, simpangan baku, dan koefisien keragaman, sementara analisis diskriminan kanonik untuk mengidentifikasi variabel morfometrik yang paling berpengaruh dalam membedakan subpopulasi ayam kampung menurut desa. Jarak genetik antar subpopulasi dihitung berdasarkan perbedaan karakter ukuran tubuh dan divisualisasikan dalam bentuk fenogram. Hasil penelitian menunjukkan bobot badan dan ukuran-ukuran tubuh ayam kampung di Kecamatan Leihitu Barat memiliki tingkat keragaman yang tinggi antara satu desa dengan desa lainnya, dan ayam jantan memiliki nilai rata-rata yang lebih besar daripada ayam betina juga baik bobot badan maupun semua sifat ukuran tubuh yang diukur. Panjang jari ketiga merupakan ukuran tubuh yang paling berperan dalam membedakan subpopulasi ayam kampung. Berdasarkan jarak genetiknya, subpopulasi ayam kampung di Desa Larike dan Liliboy memiiki hubungan kekerabatan paling dekat, diikuti oleh Desa Hatu dan Allang yang juga dekat dan membentuk satu kelompok genetik yang homogen, dan Desa Wakasihu menunjukkan jarak genetik paling jauh, membentuk klaster tersendiri. ABSTRACT This study aims to determine the diversity of body weight and body size, and analyze the genetic distance of native chickens in Leihitu Barat District, Central Maluku Regency. Data were collected through observation and measurement of samples of 196 adult male and female chickens from five villages, namely Hatu, Liliboy, Allang, Wakasihu, and Larike, which represent the native chicken population. The morphometric variables observed included body weight, chest circumference, wing length, thigh length, calf length, shank length, third toe length, and pubic width. Descriptive statistical analysis was used to calculate the mean, standard deviation, and coefficient of variation, while canonical discriminant analysis was used to identify the most influential morphometric variables in differentiating native chicken subpopulations according to village. Genetic distance between subpopulations was calculated based on differences in body size characters and visualized in the form of a phenogram. The results of the study showed that the body weight and body measurements of native chickens in West Leihitu District still have a high level of diversity between one village and another, and roosters have a greater average value than hens also in all body size traits measured. The length of the third toe is the body measurements that play the most role in distinguishing the subpopulations of native chickens. Based on their genetic distance, the subpopulations of native chickens in Larike and Liliboy Villages have the closest kinship relationship, followed by Hatu and Allang Villages, which are also close and form a homogeneous genetic group, and Wakasihu Village shows the farthest genetic distance, forming its own cluster.

Abstract

Penelitian ini bertujuan untuk mengevaluasi pengaruh penambahan molases terhadap kualitas fisik dan kimia silase rumput zanzibar (Pennisetum purpureum cv. Zanzibar). Penelitian menggunakan rancangan acak lengkap (RAL) dengan empat perlakuan dan tiga ulangan, yaitu P0 (rumput zanzibar 1000 g + 0 g molases), P1 (rumput zanzibar 1000 g + 25 g molases), P2 (rumput zanzibar 1000 g + 50 g molases), dan P3 (rumput zanzibar 1000 g + 75 g molases). Variabel yang diamati meliputi kualitas fisik (warna, tekstur, aroma, dan pertumbuhan jamur), pH silase, serta kualitas kimia (kadar air, lemak kasar, protein kasar, serat kasar, dan kadar abu). Hasil penelitian menunjukkan penambahan molases tidak berpengaruh nyata terhadap kualitas fisik, kadar air dan lemak kasar, namun berpengaruh nyata terhadap kandungan protein kasar, serat kasar dan kadar abu silase rumput zanzibar. Penambahan molases hingga level 7,5% (perlakuan P3) menghasilkan silase dengan karakteristik fisik terbaik, ditandai dengan warna hijau kekuningan, tekstur lembut, aroma asam segar tanpa adanya jamur, serta nilai pH terendah yaitu 3,2. Secara kimia, peningkatan dosis molases mampu meningkatkan kandungan protein kasar dari 11,15% (P0) menjadi 14,52% (P3) dan menurunkan kadar serat kasar dari 26,18% menjadi 23,88%. Penggunaan molases pada level 7,5% dari bobot hijauan segar dapat digunakan sebagai dosis optimal untuk menghasilkan kualitas silase rumput zanzibar yang baik. ABSTRACT This study aimed to evaluate the effect of molasses addition on the physical and chemical quality of zanzibar grass silage (Pennisetum purpureum cv. Zanzibar). The study used a completely randomized design (CRD) with four treatments and three replications, namely P0 (1000 g zanzibar grass + 0 g molasses), P1 (1000 g zanzibar grass + 25 g molasses), P2 (1000 g zanzibar grass + 50 g molasses), and P3 (1000 g zanzibar grass + 75 g molasses). The variables observed included physical quality (color, texture, aroma, and fungal growth), silage pH, and chemical quality (water content, crude fat, crude protein, crude fiber, and ash content). The results showed that the addition of molasses did not significantly affect the physical quality, water content, and crude fat, but significantly affected the crude protein content, crude fiber, and ash content of zanzibar grass silage. The addition of molasses up to 7.5% (treatment P3) produced silage with the best physical characteristics, characterized by a yellowish green color, soft texture, fresh sour aroma without mold, and the lowest pH value of 3.2. Chemically, increasing the dose of molasses was able to increase the crude protein content from 11.15% (P0) to 14.52% (P3) and reduce the crude fiber content from 26.18% to 23.88%. The use of molasses at 7.5% of the fresh forage weight can be used as an optimal dose to produce good-quality zanzibar grass silage.
