Abstract

This study was conducted to determine the best duration of hormone addition through the feed to induce the sex ratio of common carp strain Sinyonya. The study was using a completely randomized design with 5 different treatments namely A (control), B (30 days), C (35 days), D (40 days), and E (45 days) and each performed in 3 replications. The fish samples used in this study were a common carp strain Sinyonya larvae 5 days after hatching and still have the egg yolks. A total of 1.500 larvae of fish larvae were used. The fish larvae were given feed that had been mixed with 17a-methyltestosteron hormone. Feed was provided ad hormonal satiation at 5 times a day, (08.00, 10.00, 12.00, 14.00 and 16.00). The average percentage of the male fish with the highest value obtained in treatment C (35 days) is equal to 100.00±0.00. The result showed that the addition of 17a-methyltestosterone hormone on feed for 35 days and 40 days was the best treatment to improve the sex ratio of male of common carp strain Sinyonya.

Abstract

Suatu kajian dengan tujuan untuk mengevaluasi profil nutrien biji melon (Cucumis melo) sebagai kandidat bahan bahan baku pakan ikan telah dilakukan. Biji buah melon diambil dari pembuatan jus atau pengolahan buah melon yang terdapat di Kota Serang, Provinsi Banten. Biji melon dibuat tepung. Sebagian tepung biji melon diambil untuk penurunan kandungan lemaknya melalui metode hydraulic pressing pada suhu 30oC selama 120 menit. Sampel tepung biji melon yang tidak diolah dan diolah diambil untuk analisis kandungan proksimat dan profil asam amino. Hasil kajian menunjukkan buah melon memiliki rata 332,80±16,30 biji melon dengan berat rata-rata 8,52 ± 0,16 g biji melon. Tepung biji melon mengandung 24,37% protein kasar, 30,48% lemak kasar, 15,03% serat kasar dan 3,94% abu. Bila kandungan lemak dikurangi menjadi 4,26%, kandungan protein meningkat hingga 40,89%. Biji melon memiliki kandungan asam amino esensial yang lengkap, namun kekurangan metionin dan triptofan. Hal ini menunjukkan bahwa biji melon berpotensi digunakan sumber protein dan minyak nabati untuk bahan baku pakan.

Abstract

Along with the rapid pace of development, therefore one of the consequences that must be addressed is the reduction in fresh water resources, especially in urban areas and reduced cultivated land. One of the technological innovations that can be applied to integrated fish farming with crop through aquaponics system. At this time various types of tilapia developed by the fish farmer, such as tilapia BEST, Sultana and Gesit. The performance of three strains should be tested with aquaponics system so that farmers can choose the right strain and use the land and water availability are difficult. This study was aimed to evaluate the three strains of tilapia in aquaponics technology systems that support the growth and survival rates are optimal. This study applied a completely randomized experimental design comprising three strains of tilapia namely BEST, Sultana and Gesit and each in three replicates. These results indicate that the differences in the three strains of tilapia (BEST, Sultana and Gesit) did not have a significant influence on the specific growth rate, but the real impact against the survival rate and feed conversion ratio. Sultana tilapia and tilapia BEST maintained at aquaponics system gives a better effect on the survival rate and feed conversion ratio. The survival rate of tilapia Sultana of 100%0,00 and tilapia BEST amounted to 98.41%±1,37 in the feed conversion ratio of tilapia Sultana of 1.27%±0,003 and tilapia BEST of 1.29%±0,01.

Abstract

Salah satu potensi sumber daya perikanan dan kelautan di Selat Sunda yang belum dimanfaatkan dengan optimal adalah produksi garam. Padahal kebutuhan garam di pesisir Selat Sunda khususnya di Kabupaten Pandeglang sangat tinggi, khususnya untuk kebutuhan usaha pengolahan ikan. Keterbatasan teknologi dan kapasitas masyarakat untuk dapat memproduksi garam khususnya di Desa Panimbangjaya menjadi kendala utama yang perlu diselesaikan. Kegiatan ini bertujuan untuk meningkatkan kapasitas masyarakat dan introduksi teknologi tunnel untuk memproduksi garam di Desa Panimbangjaya. Introduksi teknologi tunnel garam telah dilakukan pada Bulan Juli 2024 dengan luasan tunnel 80 m² yang dibagi menjadi empat meja kristalisasi. Peningkatan kapasitas kelompok melalui penyuluhan dan pendampingan produksi garam telah dilakukan dan dalam satu siklus dapat menghasilkan garam dengan berat 12 kg per meja kristalisasi. Peningkatan kualitas air baku yang akan digunakan untuk produki garam masih diperlukan sehingga dalam satu siklus diharapkan dapat meningkatkan volume garam yang dihasilkan. Garam yang dihasilkan dapat dimanfaatkan untuk memenuhi kebutuhan garam pada usaha pengolahan ikan asin di Desa Panimbangjaya. Tumbuh dan berkembangnya produksi garam dengan sistem tunnel diharapkan dapat menyediakan lapangan pekerjaan, menumbuhkan pusat ekonomi baru sehingga kebutuhan garam di Desa Panimbangjaya tidak lagi bergantung pada pasokan garam dari Indramayu dan Cirebon.

Abstract

Cyprinus carpio Linnaeus is a leading commodity for cultivation in Pandeglang Regency, Banten Province. One of the hormones that can stimulate fish growth is the recombinant Epinephelus lanceolatus growth hormone (rElGH) in artificial feed. The research aimed to determine the optimal dose of rElGH used in artificial feed on the growth and survival of Sinyonya. The common carp of Sinyonya initial weight of 2 g was reared in an aquarium with volume 72 L. The research design used was completely randomized design with four treatments, namely (A) control, (B) rElGH 3 mg/kg, (C) rElGH 6 mg/kg, and (D) rElGH 9 mg/kg and each treatment consisted of three replications. The results showed that the absolute weight of Sinyonya carp juvenile treated with treatment B produced the best biomass of 3.22±0.06 g, treatment C 3.14±0.05 g, treatment D 3.04±0 .08 g, and treatment A 2.62±0.06 g.  The best survival rate in treatment B was 100%, treatment C 97.67%, treatment D 97.67%, and treatment A 93.33%. The feed consumed by treatment A 199.27 g, treatment B was 196.07 g, treatment C was 194.77 g, and treatment D was 195.33 g. The specific growth rate of treatment A 7.49%, treatment B 9.12%, treatment C 8.97%, and treatment D 8.69%. The feed conversion ratio for treatment B is 4,10%, treatment C 4.,16%, treatment D 4,32, and treatment A 5.,24% . The addition of rElGH to feed resulted in better growth and survival compared to the control treatment. Feeding with rElGH 3 mg/kg for 35 days was able to improve growth performance in the common carp Sinyonya.

Abstract

This study was aimed to evaluate the use of corn steep powder (CSP) as a plant protein source in Oreochromis niloticus diet. A commercial feed with 28% protein content and 368 kcal/g energy was used as reference diet, while the test feed consisting of various CSP content, namely 0%, 10%, 20%, and 30% and feed containing soybean meal (SBM) at the level of 20% and 30%. Tilapia were used in the trial with the initial body weight of 6.44 ± 0.29 g, and reared for thirty days in the aquarium at the density of fifteen and fed 3 times daily at a satiation level. All diets were supplied by 0.5% of Cr2O3 as an indicator for digestibility measurement. This study applied the completely randomized design experimental method containing six diet treatments and four replications. The result showed that CSP contains 40.27% protein, 26.10% lactic acid, and minerals. CSP is low in crude fiber and anti-nutritional factors. This study results that increasing the level of CSP significantly decreased feed acidity (P <0.05) compared to the control. The addition of CSP 20% increased feed digestibility including protein, lipid, energy, and dry matter digestibility. CSP 20% treatment increased final body weight, specific growth rate and reduced feed conversion ratio significantly (P<0.05) compare to other treatments. In conclusion, CSP can be used up to 20% to improve the growth performance of tilapia. Keyword: corn steep powder, feed digestibility, growth performance, tilapia ABSTRAK Penelitian ini bertujuan mengevaluasi penggunaan corn steep powder (CSP) sebagai sumber protein nabati pada pakan ikan nila Oreochromis niloticus.

Abstract

This study aimed to observe the digestibility performance, digestive enzyme activity, and growth performance of the common carp using corn-steep liquor (CSL). The reference diet used commercial feed with 30% protein, and the test diet used CSL at 0% (CSL0), 10% (CSL10), 20% (CSL20), and 30% (CSL30). Common carp (9.38 ± 0.73 g) were stocked at 10 fish per aquarium. Feeding was performed until apparent satiation thrice daily for the 45-day maintenance period. The study used a completely randomized design with four treatments and four replications. The results showed that CSL contained 44.04% protein and an essential amino acid index of 0.80. The additional dose of CSL reduced feed pH and stomach pH compared to the control due to the lactic acid content. In addition, CSL elevated the activity of protease, amylase, and lipase enzymes in the digestive tract of common carp. By applying 20% dose in formulated diet, CSL could increase the total digestibility, ingredient digestibility, protein digestibility, lipid digestibility, and energy digestibility. The high feed digestibility value in the CSL20 treatment was due to the fish ability to utilize carbohydrates and fats as non-protein energy sources, thus producing higher final weight, daily growth rate, and feed conversion ratio. The results of this study indicate that CSL can be used as a source of plant protein for the common carp diet, whereas an administration of CSL at 20% in diet improves the digestibility performance, digestive enzyme activity, and growth performance of common carp. Keywords: common carp, corn steep liquor, digestibility, enzyme, growth ABSTRAK Tujuan penelitian ini untuk melihat kinerja kecernaan, aktivitas enzim pencernaan dan pertumbuhan ikan mas Sinyonya (Cyprinus carpio) menggunakan bahan baku corn steep liquor (CSL) sebagai sumber protein nabati. Pakan acuan menggunakan pakan komersial dengan protein 30% dan pakan uji menggunakan CSL sebanyak 0% (CSL0), 10% (CSL10), 20% (CSL20) dan 30% (CSL30). Pengukuran kecernaan menggunakan indikator Cr2O3 0,5 %. Ikan mas Sinyonya dengan bobot tubuh rata-rata 9,38 ± 0,73 g dipelihara dalam akuarium 60×50×40 cm3 dengan kepadatan 10 ekor per akuarium. Pakan diberikan secara at satiation sebanyak 3 kali sehari selama 45 hari masa pemeliharaan. Penelitian menggunakan desain rancangan acak lengkap dengan empat perlakuan dan masing-masing empat ulangan. Hasil penelitian menunjukkan bahwa CSL mengandung protein sebesar 44,04%, dan indeks asam amino essensial 0,80. Penambahan dosis CSL secara signifikan menurunkan pH pakan dan pH lambung dibandingkan dengan kontrol karena kandungan asam laktat. Sampai dengan dosis CSL 20%, dapat meningkatkan aktivitas enzim protease, amilase dan lipase pada saluran pencernaan ikan mas Sinyonya. Di samping itu, penambahan CSL 20% meningkatkan nilai kecernaan total, kecernaan bahan, kecernaan lemak dan kecernaan energi. Nilai kecernaan pakan yang tinggi pada perlakuan CSL20 disebabkan karena kemampuan ikan dalam memanfaatkan karbohidrat dan lemak sebagai sumber energi non-protein. Disamping itu penambahan CSL sampai dengan dosis 20% meningkatkan bobot akhir, laju pertumbuhan harian dan rasio konversi pakan. Hasil penelitian ini menunjukkan bahwa CSL dapat digunakan sebagai sumber protein nabati untuk pakan ikan mas Sinyonya dan pemberian CSL pada level 20% dapat meningkatkan kinerja kecernaan, aktivitas enzim pencernaan dan pertumbuhan ikan.

Abstract

Plastic is a product that is currently popular among people, but over time plastic can be dangerous for the environment. Plastic can degrade into smaller particles known as microplastics. Microplastics in waters can harm aquatic biota such as fish. The size of microplastics is so small that it easily enters the fish's body, settles in the digestive tract and affects the fish's life cycle. Apart from biota, microplastics also pollute water and sediment. The aim of this research is to determine the abundance of microplastics and identify the characteristics of microplastics in milkfish in ponds in Muncung Village. The method used is take fish from ponds at 6 stations along with water and sediment. The fish were dissected and the digestive organs and flesh were removed, while the water and sediment were treated with NaCl. The microplastics found will be tested by FTIR to determine the polymer. The results of the observations showed that there were 3 types of microplastics, namely fragments, fibers and films. The highest abundance in organs was in the intestine, while microplastics were also found in water and sediment. FTIR test results show 6 plastic polymers in milkfish, namely ABS, latex, PVC, PP, EVA and nitrile. Keywords: Microplastics, milkfish, FTIR, Muncung Village
