Abstract

ABSTRACTThis study aims to examine the effect of adding local taro starch stabilizer (Colocasia esculenta) to physicochemical properties (viscosity and sineresis) and acidity (pH and total acid) of yogurt at room temperature incubation. The material used includes: cow milk; skim milk; starch from taro tubers from the traditional market of Malang, East Java; starter of lactic acid bacteria (S. thermophillus, L. bulgaricus, and L. acidhopilus). The research method used was a completely randomized laboratory experiment consisting of 6 treatments of adding taro starch, namely: P0: 0% (without taro starch); P1: 0.5%; P2: 1%; P3: 1.5%; P4: 2%; and P5: 2.5%. Pasteurization of milk at 85 °C for 30 minutes, addition of starter BAL 3% with an incubation period of 24 hours at room temperature. Each treatment was repeated 4 times. The data obtained were analyzed using the Variant Analysis method, if the treatment gave effect then continued with Duncan's Multiple Distance Test (UJBD). The results showed that there was a very significant effect (P <0.01) of the addition of taro starch to the viscosity, syneresis, pH, and total acid of yogurt at room temperature incubation. The addition of different concentrations of taro starch stabilizer varies the values of viscosity (1007.5-4596.25 cP), sineresis (10.11-20.33%), pH (4.16-4.20) and total acid (0,94-1.08%) yogurt. The conclusion of this study is the addition of local taro starch stabilizer up to 2.5% concentration providing optimal physicochemical and acidity properties of yogurt. ABSTRAKPenelitian ini bertujuan untuk menguji pengaruh penambahan stabilizer pati talas lokal (Colocasia esculenta) terhadap sifat fisiko (viskositas dan sineresis) dan keasaman (pH dan total asam) yogurt pada inkubasi suhu ruang. Materi yang digunakan meliputi: susu sapi; susu skim; pati dari umbi talas yang berasal dari pasar tradisional Kota Malang, Jawa Timur; starter bakteri asam laktat (S. thermophillus, L. bulgaricus, dan L. acidhopilus). Metode penelitian yang digunakan adalah percobaan laboratorium dengan rancangan acak lengkap yang terdiri dari 6 perlakuan  penambahan pati talas yaitu  P0: 0% (tanpa pati talas); P1: 0,5%; P2: 1%; P3: 1,5%; P4: 2%; dan P5: 2,5%.

Abstract

ABSTRAKPenelitian ini bertujuan untuk mengevaluasi optimalisasi penggunaan level sabun kalsium yang berbeda dalam ransum secara in vitro terhadap karakteristik fermentasi, populasi mikroba dan kecernaan nutrien ransum, menggunakan sumber inokulum cairan rumen sapi Bali. Penelitian dilaksanakan menggunakan rancangan acak kelompok dengan 4 jenis perlakuan dalam 3 ulangan.  Ransum penelitian terdiri atas : R1, 40% rumput lapang (RL) + 60% konsentrat (K), R2 (40% RL + 60% K, mengandungn 2.5% SCa-kedelai), R3 (40%  RL + 60% K, mengandung 5% SCa-kedelai), R4 (40%  RL + 60% K, mengandung 7.5% SCa-kedelai). Variabel yang diukur terdiri atas karakteristik fermentasi in vitro (pH, N-NH3, produksi total volatile fatty acids), populasi mikroorganisme (total bakteri dan total protozoa), dan kecernaan nutrien (kecernaan bahan kering dan kecernaan bahan organik). Data dianalisis menggunakan analysis of varians  (ANOVA) dan perbedaan antara perlakuan diuji dengan Duncan’s Multiple Range Test.  Hasil penelitian menunjukkan, penambahan SCa-kedelai pada level yang berbeda dalam konsentrat tidak mempengaruhi pH, konsentrasi amonia, populasi mikroba, kecernaan bahan kering dan kecernaan bahan organik fermentasi tetapi berpengaruh sangat nyata (P<0.002) terhadap produksi total VFA. Produksi total VFA tertinggi diperoleh pada ransum perlakuan R4 (konsentrat yang mengandung 7.5% SCa-kedelai). Produksi total VFA tertinggi diperoleh pada perlakuan R4 dan produksi total VFA paling rendah terjadi pada perlakuan ransum R1 (kontrol).  Produksi total VFA  ransum R1 dan R2 dan ransum R2 dan R3 tidak berbeda nyata namun produksi total VFA ransum R3 lebih tinggi dibanding ransum kontrol. Penambahan SCa-kedelai dalam konsentrat menghasilkan produksi total VFA tetinggi namun mulai menekan populasi total bakteri. Mempertimbangkan hasil peubah fermentasi dan populasi mikroba serta biaya pembuatan produk sabun kalsium, SCa-kedelai pada level 5% merupakan level penggunaan SCa-kedelai yang terbaik dalam ransum.Kata kunci: sabun kalsium, fermentasi, in vitro, kecernaanABSTRACTThe study to evaluate the optimalization the different level of soybean oil calcium soap (CaS-soybean) in ration on in vitro fermentation using Bali cattle rumen fluid. The experiment was arranged in a complete randomized block design with 4 different ration treatments and 3 replicates. Ration treatments were R1: 40% native grass (NG) + 60% concentrate (C), R2 : 40% NG + 60% C, supplemented with 2.5% soybean oil calcium soap (CaS-soybean), and R3 (40% NG + 60% C, supplemented with 5.0% CaS-soybean and R4 (40% NG + 60% C, supplemented with 7.5% CaS-soybean). Variables measured were fermentation characteristics (pH, NH3-N, total volatile fatty acids), microbial population (total bacteria and total protozoa), and nutrient digestibility (dry matter and organic matter digestibility). Data were analyzed using analysis of variance (ANOVA) and the differences between treatments means were examined by Duncan Multiple Range Test. Results of the study  showed that the four different level of CaS-soybean in ration did not have any significant effect (P>0,05) on pH, NH3-N, total bacteria, total protozoa, dry matter and organic matter digestibility. The treatments significantly increased (P<0.05) the production of total volatile fatty acids.  The highest production of total VFA was obtained from ration R4 (concentrate containing 7.5% CaS-soybean) and the lowest was obtained from treatment R1 (control). There were no significant differences between R1 and  R2, and between R2 and R3 on the total VFA production. However, the total productions of VFA in ration R3 were higher than that of the control ration. The addition of CaS-soybean in the concentrate had increased the total production of VFA, but at the same time, it began pressing the total population of bacteria. Considering the results of the fermentation variables and microbial population as well as the cost of making calcium soap products, CaS-soybean at 5% level was selected as the best level of CaS-soybean in ration.Keywords : calcium soap, fermentation, in vitro, digestibility

Abstract

ABSTRAKTujuan penelitian ini adalah mengetahui proses fermentasi yang tepat digunakan untuk meningkatkan kualitas protein kasar dan serat kasar pada biji kecipir dan menentukan level terbaik penambahan jamur Trichoderma viride yang mampu meningkatkan kualitas protein kasar dan serat kasar pada biji kecipir sehingga mampu meningkatkan kualitas dan tingkat kecernaan. Produk yang akan dihasilkan pada penelitian ini adalah alaternatif pakan fermentasi biji kecipir (Psophocarpus tetragonolobus) untuk peternak unggas. Penelitian ini menggunakan rancangan acak lengkap dengan empat perlakuan yaitu P0 = biji kecipir dengan 10% tepung jagung tanpa fermentasi; P1 = Biji kecipir dengan 10% tepung jagung + 0,1% jamur Trichoderma viride (Tv); P2 = biji kecipir dengan 10% tepung jagung + 0,2% Tv; dan P3 = biji kecipir dengan 10% tepung jagung + 0,3% Tv. Materi yang digunakan adalah biji kecipir yang dihaluskan digunakan sebagai substrat dan dihomogenkan dengan cara diaduk. Masing-masing sampel perlakukan ditimbang sebanyak 100 g, kemudian dimasukkan ke dalam kantong plastik dengan ketebalan 2 cm  dan dilubangi agar tercipta suasana aerob. Selanjutnya diinkubasikan dalam ruang fermentor pada suhu 30oC selama 7 hari. Masing-masing perlakuan diulang sebanyak 3 kali. Peubah yang diamati pH, suhu, protein kasar dan serat kasar. Berdasarkan penelitian ini dapat disimpulkan bahwa terjadi perubahan suhu, penurunan pH, serta kenaikan pada protein kasar dan penurunan serat kasar.Kata kunci: biji kecipir, Trichoderma viride, pH, suhu, protein, serat kasar ABSTRACTThe purpose of this study was to determine the proper fermentation process used to improve the quality of crude protein and crude fiber in winged beans and the best level of addition of Trichoderma viride fungus which could improve the quality of crude protein and crude fiber in winged beans to improve feed quality and digestibility. The result product of this study is an alternative fermented winged bean (Psophocarpus tetragonolobus) feed for poultry farmers. This study utilized completely randomized design with four treatments. P0 = Unfermented winged beans with cornstarch, P1 = winged beans with 10% cornstarch + 0,1% Trichoderma viride fungus (Tv), P2 = winged beans with 10% cornstarch + 0,2% Tv, P3 = winged beans with 10% cornstarch + 0,3% Tv. The material used were powdered winged beans as substrate then homogenized by stirring. Each sample was weighed 100 g, then put into a plastic bag with a 2 cm thickness and perforated to create an aerobic atmosphere. Subsequently, the sample was incubated in a fermenter room at 30oC for 7 days. Each treatment was repeated 3 times. Variables observed for pH, temperature, crude protein, and crude fiber. The result of this study concluded that there were change in temperature, decrease in pH, increase in crude protein, and decrease in crude fiber.Keywords: winged beans, Trichoderma viride, pH, temperature, protein, crude fiber

Abstract

Salah satu persoalan yang terjadi di daerah sentra  produksi  adalah pemotongan betina produktif. Fenomena tersebut diduga terjadi pula di Timor Barat sebagai salah satu daerah kantong produksi sapi bali. Sapi bali adalah salah satu plasma nuftah yang memiliki persoalan sistemik karena melibatkan banyak pelaku. Penelitian ini bertujuan untuk mengetahui upaya pengendalian pemotongan betina produktif dalam manajemen dan kelembagaan aktual. Pendekatan pemahaman sistem  agribisnis sapi bali di Timor Barat dilakukan dengan prespektif dinamika sistem. Informan kunci ditentukan melalui pemetaan pelaku dalam rantai pasok sapi bali. Penentuan informan kunci menggunakan metode snow ball sampling. Banyaknya informan kunci tergantung pada kejenuhan informasi yang diperoleh. Data, informasi, dan pengetahuan primer dikumpulkan berdasarkan observasi, focuss group diskusi (FGD), dan wawancara mendalam (indepth study)  dengan informan kunci. Jenis data yang dikumpulkan terdiri atas: data numerik, data tertulis, dan model mental. Pemodelan dengan dinamika sistem akan menggunakan perangkat lunak Ventana Simulation (Vensim). Hasil analisis dan pembahasan menunjukkan manajemen dan kelembagaan aktual yang melibatkan berbagai pelaku dalam sistem ketersediaan daging sapi untuk pasar lokal belum memiliki peran untuk pengendalian pemotongan betina produktif. Kebijakan yang diperlukan untuk mengendalikan pemotongan sapi bali betina produktif, adalah meningkatkan calf crop dan menekan mortalitas.Kata kunci: betina produktif, pemotongan, sapi bali, sistem, Timor Barat. ABSTRACTOne of the problems that occur in the center of production is slaughtering productive cows. This phenomenon is thought to occur in West Timor as one of the production center of bali cattle production. Bali cattle are one of the plasma nuftah which has systemic problems due to involve many actors. This study aims to determine the efforts to control the slaughtering of productive cows in actual management and institutions. An understanding approach to the bali cattle agribusiness system is carried out with a perspective dynamics system. Key informants were determined through mapping of actors in the supply chain of bali cattle. Determination of key informants is applying the snow ball sampling methods. Data are collected based on observation, FGD, and in-depth interviews. Data collected consists of: numeric and written data, and also mental models. Modeling with dynamics system will use Vensim software. The results show that actual management and institutions do not yet have a role to control the slaughtering of productive cows. The policy needed to control the slaughter of productive bali cows is to increase calf crop and  reduce mortality.Keywords: productive, slaughtering, bali cows, system, West Timor
