Abstract

Penelitian bertujuan mengkaji karakteristik fisiko-kimia briket bioarang campuran arang kotoran kambing dan mayang lontar. Materi yang digunakan adalah arang kotoran kambing, arang mayang lontar, dan tapioka. Penelitian menggunakan Rancangan Acak Lengkap dengan 4 perlakuan dan 4 ulangan. Perlakuan tersebut adalah P1 = arang kotoran kambing 25% + arang mayang lontar 75%, P2 = arang kotoran kambing 50% + arang mayang lontar 50%, P3 = arang kotoran kambing 75% + arang mayang lontar 25%, P4 = arang kotoran kambing 100% tanpa arang mayang lontar. Variabel yang diteliti adalah rendemen briket, densitas, kadar air, kadar abu, dan nilai kalor. Hasil sidik ragam menunjukkan campuran arang kotoran kambing dan mayang lontar memberikan pengaruh yang sangat nyata (P<0,01) terhadap kadar air dan abu, tetapi tidak nyata (P>0,05) terhadap rendemen, densitas dan nilai kalor. Disimpulkan bahwa semakin banyak arang kotoran kambing menghasilkan briket dengan kadar air dan kadar abu yang meningkat sedangkan rendemen, densitas, dan nilai kalor cenderung sama. Karakteristik fisiko-kimia briket bioarang terbaik didapatkan pada campuran arang kotoran kambing 50 % dan mayang lontar 50 %.

Abstract

This study was aimed to determine the effect of substitution level of Bothhriochloa pertusa grass with water spinach on pH, Volatile Fatty Acid, Concentration and ammonia in rumen fluid of peanut goat livestock. This study used 4 male kacang goats aged 8-1,5 years with a body weight range of 13,3-19,8 kg with an average of 16,2 kg. This study used a Latin Square design (RBSL) with four treatments and four replication periods. The four treatments were P0: Bothriochloa pertusa grass 60% + leucaena leucochephala 40%, P1: Bothriochloa pertusa grass 45% + leucaena leucochephala 40% + water spinach 15%, P2: Bothriochloa pertusa grass 30% + leucaena leucochephala 40% + water spinach 30%, P3: Botriochloa pertusa grass 15% + leucaena leucochephala 40% + water spinach 45%. Parameters measured were pH, Vollatile Fatty Acid (VFA) and Ammonia (NH3). The data obtained were analysed using Analisis of Variace (ANOVA. The results of this study indicate that pH, P0: 5.89 ± 0.22b, P1: 5,82 ± 0,1b, P2: 5,72 ± 0,17ab, P3: 5,57 ± 0,1a . VFA (mM), P0: 132,03 ± 3,99a, P1: 127,14 ± 3,99a, P2: 129,58 ± 6,31a, P3: 132,76 ± 4,95a. NH3 (mg/dl), P0: 15,89 ± 2,12a, P1: 15,14 ± 0,97a, P2: 15,52 ± 2,45a, P3: 16,41 ± 0,1a. The results of statistical analysis showed that the effect was not significant on the concentration of pH, concentration of VFA and rumen fluid ammonia of peanut goads. The conclusion of this study is that the substitusion of Bothriochloa pertusa grass with water spinach at different levels has the same effect between the treatments on pH, VFA concentration and rumen fluid ammonia of male peanut goat.

Abstract

This study aims to determine the effect of the level and length of time of fermentation of corn cobs using EM4 on the content of crude protein, crude fat, ash content, and energy. This study used a completely randomized design with 6 treatment factorial patterns with 3 replications. The use of RAL factorial pattern has two factors. The first factor (A) is the EM4 dose which is divided into 3 levels, namely: A1 = 10 ml, A2 = 15 ml, A3 = 20 ml and the second factor (B) is the fermentation time which is divided into 2 levels, namely: B1 = 7 days and B2 = 14 days. The variables studied included crude protein content, crude fat content, ash content and energy. The resulting data were analyzed statistically using analysis of variance with the help of SPSS 21. The average of the analysis results for crude protein content (5.723%), crude fat content (0.753%), ash content (2.722%) and energy (17.039%) showed no interaction (P>0.05) between EM4 level and corncob fermentation time. It was concluded that the use of EM4 solution with different levels in the corn cob fermentation process had no significant effect (P>0.05) on crude protein content, crude fat content, ash content and energy. Fermentation time had no significant effect (P>0.05) on crude protein content, crude fat content and energy but had a significant effect (P<0.05) on ash content.
