This research aimed to investigate the potential use of banana peels waste for sheep feeding. Completely randomized design was used to compare the chemical, phenol, and tannin compositions between raw and ripened banana peels from 4 different varieties (Ambon, Muli, Nangka, Kapas). Moreover, a 2x4 factorial design was used to test the main effects of ripening stages (raw, ripened) and doses (10, 20, 30, 40%) of Ambon banana peels on in vitro dry matter and organic matter digestibility (DMD and OMD, %), ammonia (NH3, mM), volatile fatty acids (VFA, mM), pH, and total gas production (TGP, ml). Raw banana peels contained less (P<0.05) dry matter (DM, %) and total digestible nutrients (TDN, %) but it contained higher (P<0.05) crude fiber (CF, %) and gross energy (GE, kcal/kg) compared with ripened banana peels. Raw and ripened banana peels contained considerable amount of total phenols (TP, %) and total tannins (TT, %) although being not different (P>0.05). Based on in vitro assessments, raw Ambon banana peels had lower (P<0.001) DMD, OMD, and VFA but higher NH3 (P<0,001) than ripened ones. Adding Ambon banana peels from 10 to 40% replacing roughage in the diet increased (P<0.001) DMD, OMD, and VFA but decreased (P<0,001) NH3. Both raw and ripened Banana peels have the potential for sheep feeding based on their chemical and in vitro assessments.

AbstrakPenelitian ini bertujuan untuk mengetahui rasio terbaik Indigofera sp. dan Rumput Gajah dalam bentuk silase yang menghasilkan kecernaan serat kasar dan BETN tertinggi pada Domba Garut jantan. Penelitian ini menggunakan metode eksperimental dengan Rancangan Acak Lengkap (RAL) dan lima perlakuan. Ransum perlakuan terdiri atas silase campuran Indigofera sp. dan Rumput Gajah dengan berbagai rasio yaitu T1 (0% dan 100%), T2 (10% dan 90%), T3 (20% dan 80%), T4 (30% dan 70%), dan T5 (40% dan 60%) serta pada tiap perlakuan ditambahkan Konsentrat dalam jumlah yang sama. Setiap perlakuan diulang sebanyak lima kali. Data hasil penelitian diolah menggunakan analisis ragam dan dilanjutkan dengan Uji Jarak Berganda Duncan. Hasil analisis statistik menunjukkan bahwa pemberian pemberian silase campuran Indigofera sp. dan Rumput Gajah memberikan pengaruh terhadap kecernaan serat kasar, namun tidak memberikan pengaruh terhadap kecernaan BETN pada Domba Garut jantan. Silase campuran Indigofera sp. 20% dan Rumput Gajah 80% menghasilkan nilai kecernaan serat kasar tertinggi. Kata kunci: Indigofera sp., Rumput Gajah, Kecernaan Serat Kasar dan BETN, Domba Garut jantan. AbstractThe research aims to determine the optimum ratio of mixed silage Indigofera sp. and Elephant Grass which produces the highest crude fiber and nitrogent free extract (NFE) digestibility in Garut male sheep. Experimental method was used with a completely randomized design for five treatment based on various ratio of Indigofera sp. and Elephant Grass i.e. T1 (0% and 100%), T2 (10% and 90%), T3 (20% and 80%), T4 (30% and 70%), and T5 (40% and 60%) also in every treatment added same amount of Concentrate. Each treatment was five times repeated. The data analyzed with ANOVA test and Duncan's multiple range test. The result of statistical analysis showed that the inclution of mixed silage Indigofera sp. and Elephant Grass was significant on crude fiber digestibility, but was not significant on nitrogent free extract (NFE) digestibility. The mixed silage Indigofera sp. 20% and Elephant Grass 80% showed the highest level of crude fiber digestibility. PendahuluanPakan merupakan salah satu aspek penting dalam pemeliharaan ternak. Menurut beberapa peneliti terdahulu pakan mengambil porsi biaya produksi sampai 70% dan sangat mempengaruhi pemeliharaan suatu komoditas ternak, baik dalam segi kualitas maupun kuantitas yang dihasilkan ternak tersebut.

ABSTRAKPenelitian ini bertujuan untuk mengetahui pengaruh pemberian limbah perkebunan singkong (LPS) dalam ransum yang disuplementasi seng dan kobalt terhadap performa reproduksi domba jantan. Penelitian dilakukan pada 20 ekor domba jantan umur ±1 tahun dengan bobot badan 24,65±4,26 kg yang dialokasikan ke dalam rancangan acak kelompok pada 5 perlakuan ransum dan diberi percobaan selama 6 minggu. Di akhir penelitian diambil semen untuk evaluasi secara mikroskopis dan makroskopis. Hasil menunjukan bahwa secara makroskopis pemberian LPS menghasilkan volume semen yang sama dengan pemberian konsentrat, namun lebih tinggi dibandingkan dengan pemberian rumput saja, semua warna semen adalah krem, pH 7-7,6 dengan konsistensi yang agak encer dan kental, gerakan masa antara cukup dan baik. Evaluasi mikroskopis untuk semua perlakuan menghasilkan perbedaan yang tidak nyata (P>0,05). Suplementasi seng dan kobalt tidak memberikan banyak pengaruh terhadap semen domba. ABSTRACTThe research analyzed the effect of using cassava plantation waste (CPW) in male sheep ration supplemented by zinc (Zn) and cobalt (Co) on his semen performance. Research materials and method consisted of a year old of 20 heads of male sheep with 24.65±4.26 kg weight. These male sheep were distributed in a Block Randomized Design with 5 rations treatment for 6 weeks. At the end of research semen was collected to examine its performance on both microscopic and macroscopic basis. The results showed that all semen was cream in color with pH 7-7.6. Semen consistency was diluted to viscous with value of its mass movement from 3 (enough) to 4 (good). On macroscopic basis, the utilization of CPW in ration produced a similar volume of semen to concentrate ration, but it reached a higher volume than native grass feeding. On microscopic basis, all treatments resulted in a not significant (P<0.05) effect. Zinc and cobalt supplementation did not have a significant effect on semen quality. Thus, CPW could be used as concentrate substitution and give a slight effect on sheep semen production.

Abstract. Hidayati YA, Nurachma S, Badruzzaman DZ, Marlina ET, Harlia E. 2021. Utilization of sheep dung and rice straw with indigenous microbial agent to optimize vermicompost production and quality. Biodiversitas 22: 5445-5451. Sheep dung is a useful by product that can be potentially processed into more useful products with minimal pollution. Vermicomposting is a waste processing method that produces Solid Organic Fertilizer and worm biomass as the raw materials for drugs and cosmetics. This research aimed to utilize the role of indigenous fungi and bacteria to determine the influence of C/N ratio from sheep dung and rice straw mixture on vermicompost quality (N, P, K, Ca, Mg). This experimental research was conducted in a Completely Randomized Design with three treatments (T1: C/N ratio of 25; T2: C/N ratio 30; T3: C/N ratio 35) and six replicates for each treatment. Data so obtained were analyzed with ANOVA and Duncan's Multiple Range Test. The results showed that C/N ratio had a noticeable influence on vermicompost quality. C/N ratio 30 produced the highest vermicompost quality (N: 1.11 ± 023381%; P: 0.56 ± 0.010328 %; K: 0.51 ± 0.021369 %; Ca: 0.33 ± 0.0248 %; Mg: 0.14 ± 0.0228%).

Pelatihan pembuatan jerami padi terfermentasi untuk peternak domba telah dilaksanakan di Desa Jungjang, Kecamatan Arjawinangun, Kabupaten Cirebon dengan jumlah peserta 10 orang. Jerami padi terfermentasi dapat menjadi alternatif hijaun pakan domba menggantikan rumput yang ketersediannya semakin berkurang terutama pada musim kemarau. Pelatihan pembuatan jerami padi terfermentasi bermanfaat bagi peternak domba setempat karena hasil kuesioner menyatakan sebagian besar peternak belum mengetahui prosedur pembuatan jerami padi terfermentasi sebelumnya. Peternak juga belum mengetahui nilai manfaat teknologi fermentasi dalam meningkatkan kualitas jerami padi. Hasil kuesioner menyatakan peternak ingin mencoba membuat jerami padi terfermentasi untuk pakan domba mereka. Prosedur detail mengenai pembuatan jerami padi terfermentasi disampaikan dalam bentuk video yang dapat diunggah pada aplikasi Youtube. Peternak dapat melihat langsung contoh jerami padi terfermentasi dalam tong biru yang dibawa oleh narasumber. Kata Kunci: Pelatihan, jerami padi, fermentasi, peternak, domba.
