Abstract

This study aimed to evaluate the effects of okara (soybean residue) substitution on the physicochemical and sensory characteristics of chicken nuggets . A Completely Randomized Design was employed with four substitution levels: 0% (P0), 20% (P1), 40% (P2), and 60% (P3). Evaluated parameters included moisture content, crude fiber, pH, and sensory properties (color, aroma, taste, texture) determined by a 50-panelist hedonic test. Data were analyzed using ANOVA and Duncan's Multiple Range Test (p<0.05). The results revealed that okara substitution had a significant effect on all parameters except for texture. Sensorially, the 20% okara formulation (P1) was the most preferred, exhibiting significantly higher scores for aroma and taste compared to the control. It was concluded that a 20% substitution of okara is the optimal level to enhance sensory acceptance while modifying the physicochemical properties of spent laying hen nuggetsTujuan penelitian ini adalah untuk mengetahui pengaruh substitusi limbah susu kedelai pada proses pembuatan nugget daging ayam petelur afkir pada berbagai konsentrasi terhadap karakteristik fisikokimia dan palatabilitas. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) dengan empat taraf perlakuan substitusi limbah susu kedelai, yaitu P0 (0%), P1 (20%), P2 (40%), dan P3 (60%). Parameter yang diuji meliputi kadar air, kadar serat, derajat keasaman (pH), serta sifat organoleptik (warna, aroma, rasa, tekstur) menggunakan uji hedonik terhadap 50 panelis. Data dianalisis menggunakan Analisis sidik r dan dilanjutkan dengan Uji Jarak Berganda Duncan pada taraf signifikansi 5%. Hasil penelitian menunjukkan bahwa substitusi limbah susu kedelai berpengaruh nyata (p<0,05) terhadap semua parameter yang diuji, kecuali tekstur. Secara organoleptik, perlakuan P1 (20%) merupakan formula yang paling disukai, terutama pada atribut aroma dan rasa yang secara signifikan lebih tinggi dibandingkan kontrol. Kesimpulan penelitian ini substitusi limbah susu kedelai sebanyak 20% merupakan perlakuan optimal yang mampu meningkatkan penerimaan sensorik dan memodifikasi sifat fisikokimia nuget daging ayam petelur afkir.

Abstract

The purpose of this study was to determine the effect of feeding fermented goroho banana peel flour on giblet weight (liver, gizzard, lymph, and heart). The method used in this study was a completely randomized design (CRD) with 5 treatments and 5 replicates. The number of super native chickens used in the study was 125. The treatments consisted of P0 (Ration (0%) without fermented goroho banana peel flour), P1 (ration + 5% fermented goroho banana peel flour), P2 (ration + 10% fermented goroho banana peel flour), P3 (ration + 15% fermented goroho banana peel flour), P4 (ration + 20% fermented goroho banana peel flour). The variables observed were giblet weight, which included the gizzard, heart, liver, and lymph. The results showed that fermented goroho banana peel flour as a feed substitute had no significant effect (P>0.05) on the weight of the gizzard, liver, heart, and lymph nodes in super native chickens. In conclusion, fermented goroho banana peel flour at 5% to 20% in the ration did not affect the weight of the gizzard, heart, liver, and lymph nodes of 60-day-old super native chickens.Tujuan penelitian ini adalah untuk mengetahui pengaruh pemberian tepung kulit pisang goroho frementasi terhadap bobot giblet (hati, gizard, limfa, dan jantung). Metode yang digunakan dalam penelitian ini adalah Rancangan Acak Lengkap (RAL) dengan 5 perlakuan dan 5 ulangan. Jumlah ayam kampung super yang digunakan dalam penelitian sebanyak 125 ekor. Perlakuan terdiri atas P0 (Ransum (0%) tanpa tepung kulit pisang goroho fermentasi), P1 (Ransum + 5% tepung kulit pisang goroho fermentasi), P2 (Ransum + 10% tepung kulit pisang goroho fermentasi), P3 (Ransum + 15% tepung kulit pisang goroho fermentasi), P4 (Ransum + 20% tepung kulit pisang goroho fermentasi). Variabel yang diamati adalah bobot giblet yang meliputi: Gizzard, Jantung, Hati, dan Limfa. Hasil penelitian menunjukan bahwa tepung kulit pisang goroho fermentasi sebagai pakan pengganti ransum tidak memberikan pengaruh nyata pada bobot gizzard, hati, jantung, dan limfa pada ayam kampung super. Kesimpulannya bahwa tepung kulit pisang goroho fermentasi 5% sampai 20% dalam ransum tidak memengaruhi bobot gizzard, jantung, hati, dan limfa, ayam kampung super umur 60 hari. Namun pada persentase bobot limfa terjadi peningkatan pada P4 yang menggunakan 20% tepung kulit pisang goroho fermentasi dalam pakan.

Abstract

This study aimed to determine the effect of commercial feed provision on body weight gain and mortality of Balitnak Superior Native Chickens (KUB). The materials used were 100 day-old chicks (DOC) of KUB chickens. The commercial feeds tested were Mark Sinta (SA), Malinau (MA), Sreeya (SR), and Gold Coin (GC), while a mixed ration consisting of concentrate, ground corn, and fine rice bran served as the control treatment; all feeds were obtained from local distributors in Gorontalo. The study employed a Completely Randomized Design (CRD) with five treatments, where T1 served as the control. The results showed that the highest feed consumption occurred in treatment T5, which received the GC commercial feed, while the lowest was observed in T1 (control ration). Mortality rates in descending order were T1 (3%), T2 (2%), T3 (2%), T4 (2%), and T5 (0%). The highest body weight gain was recorded in T5 with the GC commercial feed, whereas the lowest was found in the control treatment (T1). In ascending order, body weight gain ranked as T1, T2, T3, and T4. The findings indicate that commercial rations with clearly defined protein content exert a more pronounced effect on body weight gain in KUB chickensPenelitian ini bertujuan untuk mengetahui pengaruh pemberian ransum komersil terhadap pertambahan berat badan serta mortalitas Ayam Kampung Unggulan Balitnak (KUB).

Abstract

study aims to determine the level of consumer satisfaction with processed chicken products in Kota Tengah District, Gorontalo City. As competition in the culinary business increases, especially in the fried chicken business, understanding customer satisfaction is important for businesses to maintain and increase customer loyalty. This study used a survey method with a descriptive quantitative approach. Sampling was conducted using accidental sampling techniques on 100 respondents who consumed ayam geprek products at two restaurants, namely RM Tiar and RM Uyat2. Data was collected through questionnaires and analyzed using descriptive statistics and Chi-Square tests to examine the relationship between service quality, product quality, and price on customer satisfaction levels. The results show that the service quality variable is in the neutral category with an average score of 403, while product quality and price are in the very satisfied category with average scores of 412 and 417, respectively. The Chi-Square test results show that there is no significant relationship between service quality, product quality, and price on consumer satisfaction levels (p-value > 0.05), which means that these three variables are assessed independently by consumers. This study recommends that businesses continue to improve product innovation and services in order to maintain competitiveness and customer satisfaction.Penelitian ini bertujuan untuk mengetahui tingkat kepuasan konsumen terhadap produk olahan ayam geprek di Kecamatan Kota Tengah, Kota Gorontalo. Seiring meningkatnya persaingan bisnis kuliner, khususnya usaha ayam geprek, pemahaman mengenai kepuasan konsumen menjadi penting bagi pelaku usaha untuk mempertahankan dan meningkatkan loyalitas pelanggan. Penelitian ini menggunakan metode survei dengan pendekatan kuantitatif deskriptif. Pengambilan sampel dilakukan dengan teknik accidental sampling terhadap 100 responden yang mengonsumsi produk ayam geprek pada dua rumah makan, yaitu RM Tiar dan RM Uyat2. Data dikumpulkan melalui kuesioner dan dianalisis menggunakan statistik deskriptif serta uji Chi-Square untuk melihat hubungan antara kualitas pelayanan, kualitas produk, dan harga terhadap tingkat kepuasan konsumen. Hasil penelitian menunjukkan bahwa variabel kualitas pelayanan berada dalam kategori netral dengan skor rata-rata 403, sedangkan kualitas produk dan harga berada pada kategori sangat puas dengan skor rata-rata masing-masing 412 dan 417. Hasil uji Chi-Square menunjukkan tidak terdapat hubungan signifikan antara kualitas pelayanan, kualitas produk, dan harga terhadap tingkat kepuasan konsumen (p-value > 0,05), yang berarti ketiga variabel tersebut dinilai secara independen oleh konsumen. Penelitian ini merekomendasikan agar pelaku usaha terus meningkatkan inovasi produk dan pelayanan demi mempertahankan daya saing dan kepuasan konsumen.

Abstract

The dihe macaque (Macaca hecki) is one of the primates endemic to Sulawesi. This species is listed on the IUCN red list as vulnerable due to high pressure on its habitat and population. One of the distribution areas of M. hecki in Gorontalo Province is the Dulamayo Forest. However, until now, research on the population, habitat, and ecology of M. hecki has not been widely conducted. This study aims to determine the existence and estimate the population density of M. hecki in North Dulamayo village. The study was conducted for approximately 2 months (May–July 2025). The study used the strip transect sampling method for population data and vegetation analysis to determine the structure and composition of the habitat. The results of this study revealed that North Dulamayo Village is a distribution area of M. hecki, with the discovery of 31 individuals of M. hecki. Based on data analysis, the highest density was found on transect A, with a density of 19.2 individuals/Km2, while the lowest density was found on transect B, with a density of 7 individuals/Km2. Furthermore, based on the total survey area of 0.225 km2, the population density of M. hecki was 13.1 individuals/km2. The research results are expected to serve as a baseline for further research and policymaking on M. hecki conservation in Gorontalo Province, especially for population management, habitat and handling of human-wildlife conflicts. Monyet dihe (Macaca hecki) merupakan salah satu primata endemik Sulawesi. Spesies ini masuk daftar merah IUCN dengan kategori rentan akibat tingginya tekanan terhadap habitat dan populasi. Salah satu daerah sebaran M. hecki di Provinsi Gorontalo adalah Hutan Dulamayo. Namun sampai saat ini penelitian mengenai populasi, habitat dan ekologi M. hecki belum banyak dilakukan. Penelitian ini bertujuan untuk mengetahui eksistensi dan estimasi kepadatan populasi M. hecki di desa Dulamayo Utara. Penelitian dilakukan selama kurang lebih 2 bulan (Mei–Juli 2025). Penelitian menggunakan metode strip transect sampling method untuk data populasi dan analisis vegetasi untuk mengetahui stuktur dan komposisi habitat. Hasil penelitian mengungkapkan Desa Dulamayo Utara merupakan daerah sebaran M. hecki, dengan ditemukannya 31 individu M. hecki di jalur transek. Berdasarkan analisis data diperoleh kepadatan terbanyak terdapat pada jalur transek A, dengan kepadatan sebesar 19,2 ekor/Km2, sedangkan kepadatan terendah terdapat pada jalur transek B, dengan kepadatan sebesar 7 ekor/Km2. Selanjutnya, berdasarkan luas total area survey sebesar 0,225 Km2, diperoleh kepadatan populasi M. hecki sebesar 13,1 ekor/Km2. Hasil penelitian diharapkan dapat menjadi referensi awal bagi penelitian lanjutan dan pengambilan kebijakan konservasi M. hecki di Provinsi Gorontalo khususnya untuk manajemen populasi, habitat dan penanganan konflik manusia–satwa liar.

Abstract

The objective of this study was to determine the effect of corn leaf meal and seaweed meal (Eucheuma cottoni) on the weight gain of non-carcass parts. This study used 96 broiler chickens aged 15–24 days. The slatted pens are divided into 24 compartments, each measuring 100 x 50 x 100 cm. The feed provided consisted of commercial feed (BR 1), corn leaf meal, and seaweed meal. The research method used a completely randomized design (CRD) with 6 treatments and 4 replicates, The treatments included commercial feed (P0), 10% corn leaf meal (P1), 10% seaweed flour (P2), 5% corn husk flour + 15% seaweed flour (P3), 10% corn leaf flour + 10% seaweed flour (P4), 15% corn leaf flour + 5% seaweed flour (P5), and each round consists of 4 chickens. The variables observed were chicken head weight, chicken neck weight, and chicken leg weight. The data were analyzed using analysis of variance (ANOVA). The results of the study show that the addition of corn leaf meal and seaweed meal has a significant effect on the non-carcass parts of broiler chickens, including the neck, head, and legs. The best treatment was P0 (commercial feed), which produced a higher non-carcass weight than the other treatments. Increasing the levels of corn leaf meal and seaweed meal in the diet—particularly in the high-combination treatment—tended to reduce non-carcass weight. Tujuan penelitian ini adalah untuk mengetahui pengaruh tepung daun jagung dan tepung rumput laut (eucheuma cottoni) terhadap pertambahan bobot bagian-bagian non karkas. Penelitian ini menggunakan ayam broiler sebanyak 96 ekor umur 15-24 hari. Kandang yang digunakan kandang slat di kelompokkan menjadi 24 petak dengan ukuran setiap petak 100 x 50 x 100 cm. Pakan yang diberikan terdiri dari pakan jadi (BR 1), tepung daun jagung, tepung rumput laut. Metode penelitian menggunakan Rancangan Acak Lengkap (RAL) dengan 6 perlakuan dan 4 ulangan, perlakuan yang diberikan meliputi pakan komersil (P0), 10% tepung daun jagung (P1), 10% tepung rumput laut (P2), 5% tepung daun jagung + 15 % tepung rumput laut (P3), 10% tepung daun jagung + 10% tepung rumput laut (P4), 15% tepung daun jagung + 5% tepung rumput laut (P5), dan setiap ulangan terdiri dari 4 ekor ayam. Variabel yang diamati adalah bobot kepala ayam, bobot leher ayam , dan bobot kaki ayam. Data dianalisis menggunakan analisis ragam (ANOVA). Hasil penelitian menunjukkan pemberian tepung daun jagung dan tepung rumput laut memberikan pengaruh nyata terhadap bagian non karkas ayam broiler yang meliputi leher, kepala, dan kaki. Perlakuan terbaik ditunjukkan oleh P0 (pakan komersial) yang menghasilkan bobot non karkas lebih tinggi dibandingkan perlakuan yang lainnya. Peningkatan level tepung daun jagung dan tepung rumput laut dalam ransum terutama pada perlakuan dengan kombinasi tinggi, cenderung menurunkan bobot non karkas

Abstract

This study aimed to evaluate the effectiveness of young and mature green coconut water as alternative semen extenders for preserving the quality of chilled Bali bull liquid semen. The experiment was conducted over a three-month period at the Field Laboratory of the Department of Animal Science, Faculty of Science and Computer Science. A laboratory experimental approach was employed. Semen was collected once a week from two healthy Bali bulls aged 2–3 years. Young green coconut water and mature green coconut water (6–7 months of maturity) were used as alternative extenders, while CEP-2 supplemented with 10% egg yolk served as the control. The experiment was arranged in a completely randomized design (CRD) with three treatments: A1 = CEP-2 + 10% egg yolk (control), A2 = young green coconut water + 10% egg yolk, and A3 = mature green coconut water + 10% egg yolk. Each treatment was replicated ten times. The data were analyzed using analysis of variance (ANOVA) with SPSS version 20. The evaluated parameters included individual sperm motility, sperm viability, and sperm abnormalities. The results demonstrated that the highest individual sperm motility was observed in A3 (42.57 ± 2.06%), followed by A2 (41.15 ± 0.49%), with both treatments maintaining acceptable motility for up to four days of chilled storage. The highest sperm viability on Day 5 was also recorded in A3 (42.60 ± 1.71%), followed by A2 (40.50 ± 1.71%). Meanwhile, the lowest sperm abnormality throughout seven days of storage was found in A3 (1.36 ± 0.04%), followed by A2 (1.44 ± 0.10%). These findings indicate that both young and mature green coconut water can serve as effective alternative semen extenders for preserving the quality of chilled Bali bull liquid semen. However, mature green coconut water exhibited superior preservation ability by maintaining sperm motility for up to four days and sperm viability for up to five days during chilled storage. Tujuan penelitian ini mengetahui penggunaan air kelapa hijau muda dan air kepala hijau tua sebagai bahan pengencer terhadap kualitas semen cair sapi bali setelah disimpan. Penelitian ini dilakukan selama 3 bulan, bertempat di Laboratorium Lapang Program Studi Peternakan Fakultas Sains dan Ilmu Komputer. Metode yang digunakan yaitu eksperimental laboratory. Semen yang digunakan berasal dari 2 ekor sapi bali umur 2-3 tahun ditampung 1 minggu sekali. Air kepala hijau muda dan air kepala hijau tua umur 6-7 bulan serta CEP2 sebagai kontrol. Rancangan penelitian menggunakan Rancangan Acak Lengkap (RAL) pola faktorial yang terdiri dari A1 = CEP2 + KT 10% (kontrol); A2 = Air Kelapa Hijau Muda + KT 10% dan A3= Air Kelapa Hijau Tua + KT 10% dan Masing-masing perlakuan dilakukan 10 kali ulangan. Data dianalisis menggunakan Analisis Ragam (ANOVA) dengan bantuan software SPSS 20. Variabel yang di amati adalah motilitas individu, viabilitas dan abnormalitas. Hasil penelitian menunjukkan motilitas individu terbaik pada A3 (42,57 ± 2.06%) disusul A2 (41,15 ± 0.49%) yang bertahan sampai 4 hari simpan, kemudian viabilitas terbaik pada hari ke 5 adalah A3 (42,6 ± 1.71%) disusul A2 (40,5 ± 1.71%), sedangkan abnormalitas terendah sampai hari ke 7 adalah A3 (1,36 ± 0.04%) disusul A2 (1,44 ± 0.10%). Pengencer air kelapa hijau muda dan pengencer air kepala hijau tua dapat mempertahankan kualitas semen cair sapi bali dengan lama simpan selama 4 hari untuk motilitas dan 5 hari untuk viabilitas spermatozoa.
