Abstract

ABSTRAKArbila merupakan legume pakan yang jeraminya merupakan pakan hijauan yang berkualitas bagi ruminansia, dan produksi jeraminya ditentukan oleh kualitas tanah. Level bokashi yang ditambahkan mempengaruhi kualitas tanah, yang tentu berdampak pada produksi jerami arbila. Penelitian bertujuan untuk mengevaluasi produksi jerami arbila pasca panen akibat pemberian level bokashi yang berbeda. Penelitian tersebut telah dilaksanakan selama 5 bulan di Desa Noelbaki. Rancangan percobaan yang digunakan adalah rancangan acak kelompok (RAK) dengan 5 perlakuan dan 4 ulangan, terdiri atas P0 = tanpa bokashi (kontrol), P10 = penambahan bokashi 10 ton/ha, P20 = bokashi 20 ton/ha, P30 = bokashi 30 ton/ha, P40 = bokashi 40 ton/ha. Variabel yang diamati adalah  produksi bahan segar jerami (PBSJ) (ton/ha), produksi bahan kering jerami (PBKJ), produksi bahan organik jerami  (PBOJ) arbila. Data yang diperoleh dianalisis varians dan dilanjutkan dengan uji Duncan. Hasil analisis varians menunjukkan bahwa level pemberian pupuk bokashi berpengaruh sangat nyata (P<0,01) terhadap PBSJ arbila serta berpengaruh nyata (P<0,05) terhadap PBKJ dan PBOJ arbila. Berdasarkan hasil penelitian, diketahui rataan PBSJ arbila berkisar 0,46-2,52 ton/ha, PBKJ arbila berkisar 0,07-0,18 ton/ha, dan PBOJ arbila berkisar 0,04-0,16 ton/ha. Hasil uji Duncan menunjukkan bahwa nilai PBSJ, PBKJ dan PBOJ arbila tertinggi terdapat pada perlakuan P40. Disimpulkan bahwa semakin meningkatnya level bokashi Chromolaena dan feses sapi, produksi jerami arbila semakin tinggi. Level bokashi feses sapi dan Chromolaena terbaik adalah 40 ton/ha.Kata kunci: arbila, bokashi, jerami, hijauan ABSTRACTArbila’s straw is a quality feed for ruminants. Production of these straw is determined by soil quality. The level of bokashi added influences the quality of the soil and therefore influences the straw production. This research aimed to evaluate arbila’s straw production post-harvest in different levels of bokashi. This research was carried out for 5 months at Noelbaki. The experimental design used was a randomized block design (RBD) with 5 treatments and 4 replications consisting of P0 = without bokashi (control), P10 = addition of 10 tons of bokashi / ha, P20 = 20 tons of bokashi / ha, P30 = 30 tons of bokashi / ha, P40 = bokashi 40 tons / ha. The observed variables were the straw fresh weight production (SFW) (tons/ha), straw dry matter production (SDM) (tons/ha), straw organik matter production (SOM) (tons/ha). Data were analyzed for variance and continued with Duncan test. Analysis of variance showed that the level of bokashi fertilizer had a very significant effect (P <0.01) on SFW and significantly affected (P <0.05) SDM and SOM. The average SFW in this study ranged from 0.46 to 2.52 tons/ha, HDM ranges from 0.07 to 0.18 tons/ha, and SOM ranges from 0.04 to 0.16 tons/ha. Duncan's test shows that the highest SFW, SDM and SOM are found in P40. It was concluded that arbila’s straw production increases with the level of Chromolaena and cattle manure bokashi added. Highest production was shown in group with 40 ton/ha bokashi.Keywords: bokashi, forage, Phaseolus lunatus L, straw

Abstract

ABSTRAKSemen adalah cairan yang dikeluarkan oleh organ kelamin ternak jantan yang secara normal diejakulasikan ke dalam saluran reproduksi ternak betina melalui kopulasi. Evaluasi semen merupakan alat utama untuk memprediksi kinerja  reproduksi ternak ayam  jantan. Evaluasi kualitas semen penting dilakukan untuk menyelesaikan salah satu masalah utama dalam peternakan pembibitan ayam, yaitu   rendahnya fertilitas.  Faktor terbesar dari sumber masalah tersebut terkait dengan rendahnya kualitas semen ayam. Kualitas semen ayam  lebih banyak dipengaruhi oleh faktor non genetik, seperti faktor pakan dan nutrisi. Tujuan dari penulisan makalah ini adalah untuk mengkaji hasil-hasil studi terkait pengaruh pakan terhadap kualitas semen ayam. Hasil studi menunjukkan bahwa faktor pakan sangat mempengaruhi kualitas semen ayam, terutama imbangan energi metabolis-protein dalam pakan ayam jantan sangat penting diatur untuk menjaga berat badan ayam jantan agar tidak terjadi kelebihan atau kekurangan berat badan yang sangat mempengaruhi kualitas semen ayam. Suplementasi suplemen dan imbuhan pakan menjadi upaya yang dapat dilakukan untuk meningkatkan kualitas semen ayam. Jenis suplementasi yang dapat dilakukan dengan bahan sumber antioksidan, asam amino, mikromineral, bahan mengandung bioaktif tanaman, bahan sumber asam lemak dan probiotik. Disimpulkan bahwa faktor pakan sangat menentukan terhadap kualitas semen ayam.Kata kunci: ayam jantan, kualitas semen, pakanABSTRACTRooster semen is a liquid released by the genitals of the roosters which is normally ejaculated into the female reproductive tract during copulation. Semen evaluation is the main way to predict the reproductive performance of roosters. Semen quality evaluation is important to solve one of the main problems in poultry breeding farms, namely low fertility, whereas the biggest factor of this problem source is related to the poor of roosters’ semen quality. The quality of roosters semen is more influenced by non-genetic factors, such as feed and nutrition. The purpose of this paper was to examine the results of studies so far related to the effect of feed on the roosters’ semen quality. The results of the study indicated that the feed factor greatly influences the quality of roosters semen. The metabolic energy-protein balance in the rooster's feed was very important to regulate to maintain the weight of the rooster so as not to overweight and underweight because bodyweight greatly affects the quality of roosters semen. Supplementation of feed supplements and feed additives was an effort that can be done to improve the roosters semen quality. The kind of supplementation that could be done was supplementation of antioxidant sources, amino acids, microminerals, materials containing plant bioactive, fatty acid source ingredients, and probiotics. It was concluded that the feed factor was crucial to the quality of semen quality produced by the roosters.Keywords: feed, rooster, semen quality

Abstract

ABSTRACTThe use of antibiotics in chicken feed is currently banned because it can cause resistance to pathogenic bacteria and cause residues in products. This study aimed to see the effect of drinking water containing uronic acid extracted from Sargassum crassifolium (S. crassifolium) on the physical and chemical quality of Lohmann chicken eggs. One hundred and twenty laying hens were divided into 2 groups: (1) chickens given commercial feed containing antibiotics and (2) feed without additional antibiotics. The chickens were randomly assigned to one of the 5 brown seaweed supplementation treatments in drinking water A1=0.0% S.crassifolium (control); A2=2.5% S.crassifolium; A3=5.0% S.crassifolium; A4=7.5% S.crassifolium; A5=10.0% S.crassifolium. The study used a completely randomized factorial design of 5 treatments, 2 factors, and 3 replications. Each replication consisted of 6 heads of laying hens. There were no differences between treatments on the performance of laying hens (egg production, egg weight, egg mass, feed conversion); physical quality (eggshell, egg yolk, egg white, shell thickness, egg yolk, Haugh unit, egg index) and chemistry (superoxide dismutase production, thiobarbituric acid reactive substances (TBARS) and Lohmann chicken egg cholesterol) but there was a difference in feed intake. The uronic acid extracted from S. crassifolium has not been able to increase the production and quality of Lohmann chicken eggs.Keywords: lohmann chicken, quality of eggs, Sargassum crassifolium, uronic acid

ABSTRAKPenelitian ini bertujuan untuk mengevaluasi kemungkinan usaha ternak domba sebagai aktivitas nafkah untuk pengentasan kemiskinan, serta menentukan jumlah kepemilikan domba yang dapat  membawa rumah tangga buruh tani keluar dari kemiskinan. Survey telah dilakukan di Desa Walangsari Kecamatan Kalapanunggal Kabupaten Sukabumi, melibatkan rumah tangga buruh tani miskin sebanyak 65 orang dan 22 orang tidak miskin. Faktor yang berpengaruh terhadap kemiskinan dianalisis menggunakan model regresi logistik biner, sedangkan jumlah kepemilikan domba yang harus dipelihara untuk keluar dari kemiskinan ditentukan dengan model regresi sederhana. Hasil penelitian menunjukkan bahwa usia kepala keluarga, dan pengalaman beternak tidak mempengaruhi kemiskinan, sedangkan jumlah kepemilikan domba, jumlah anggota rumah tangga, keterlibatan dalam kelembagaan, serta sumber pendapatan dari non pertanian mempengaruhi status kemiskinan rumah tangga buruh tani. Pada rata-rata jumlah anggota rumah tangga sebanyak 4,45 orang,untuk keluar dari kemiskinan buruh tani harus memelihara minimal sebanyak 36,63 ekor domba per rumah tangga. Hasil penelitian ini menegaskan bahwa usaha ternak domba dapat digunakan sebagai sarana untuk pengentasan kemiskinan buruh tani, program pengentasan kemiskinan akan efektif bila melibatkan kelembagaan lokal.Kata Kunci: buruh tani, jumlah kepemilikan domba, kemiskinanABSTRACTThis study aims to determine the possibility of sheep farming as a livelihood activity for poverty alleviation and to determine the amount of sheep ownership that can bring farm laborers households out of poverty. Survey research has been carried out in Walangsari Village, Kalapanunggal District, Sukabumi Regency, involving 65 poor farmer households and 22 non-poor households. Factors affecting poverty were analyzed using a binary logistic regression model, while the number of sheep ownership needed to escape poverty was determined by a simple regression model. The results showed that the age of the head of the family, and experience of sheep farmers did not affect poverty, while the number of sheep ownership, number of household members, involvement in institutions, and sources of income from non-agriculture affected the poverty status of farm laborers' households. In the average number of household members as many as 4.45 people, to get out of poverty must maintain a minimum of 36.63 sheep per household. This research explains that sheep farming can be used as a means to reduce the poverty of farm laborers, and poverty alleviation programs will be effective if they involve local institutions.Keywords: farm labor, number of sheep ownership, poverty

Abstract

ABSTRAKAmpas teh hijau merupakan salah limbah yang berasal dari rumah tangga maupun industri pengolah teh yang ketersediaannya cukup melimpah seiring tingginya konsumsi teh masyarakat Indonesia. Ampas teh hijau dilaporkan mengandung senyawa polifenol dengan kandungan antioksidan yang tinggi namun memiliki senyawa antinutrisi yaitu tanin yang dapat menghambat proses kecernaan nutrien. Tanin dapat diminimalisir dan dihilangkan kandungannya pada ampas teh melalui proses fermentasi sehingga kecernaan dapat ditingkatkan. Penelitian bertujuan untuk mengetahui pengaruh penambahan ampas teh hijau fermentasi (ATHF) terhadap performa (pertambahan bobot badan, konversi pakan, persentase karkas) dan income over feed cost itik Cihateup. Penelitian dilakukan secara eksperimen menggunakan rancangan acak lengkap. Sebanyak 60 ekor itik Cihateup berumur sehari dikelompokkan secara acak pada 4 kelompok perlakuan pakan yang disuplementasi dengan ATHF yaitu K0 (0% ATHF), K1 (1% ATHF), K2 (2% ATHF), dan K3 (3% ATHF). Data dianalisis menggunakan ANOVA dan apabila berbeda nyata diuji lanjut dengan metode Duncan’s Multiple Range Test (DMRT). Penambahan ATHF pada pakan itik Cihateup menunjukkan perbedaan yang nyata pada parameter pertumbuhan bobot badan dan konversi pakan serta berbeda sangat nyata pada IOFC. Penambahan ampas teh hijau fermentasi pada level 1% memberikan dampak positif terhadap perbaikan pertambahan bobot badan, konversi pakan, dan IOFC.Kata kunci: ampas teh, income over feed cost, imbuhan pakan,. teh fermentasiABSTRACTGreen tea waste is one of the waste originating from households and the tea processing industry, whose availability is quite abundant in line with the high consumption of Indonesian tea. Green tea pulp is reported to contain polyphenol compounds with high antioxidant content but has an anti-nutrient compound namely tannins which can inhibit the process of nutrient digestion. Tannins can be minimized and their presence eliminated in tea waste through the fermentation process so that digestibility can be improved. The study aims to determine the effect of the addition of fermented green tea waste (ATHF) to growth performance (body weight gain, feed conversion, carcass percentage) and income over feed cost of Cihateup ducks. The research was conducted experimentally using a completely randomized design. Sixty-day-old Cihateup ducks were randomly grouped into 4 treatment groups supplemented with ATHF, namely K0 (0% ATHF), K1 (1% ATHF), K2 (2% ATHF), and K3 (3% ATHF). The data were analyzed using ANOVA and if they were significantly different, it was further tested using the Duncan's Multiple Range Test (DMRT) method. . The addition of ATHF in Cihateup duck feed showed significant differences in body weight gain parameters and feed conversion and was very significantly different in IOFC. The addition of fermented green tea waste at the level of 1% had a positive impact on improving body weight gain, feed conversion, and IOFC.Keywords: feed additive, fermented tea, tea waste, income over feed cost
