Indawan et al, 2019. Increasing Sweet Potato Yield on Biochar Amendment Application on Sub-Optimal Dry Land. JLSO 8(1):47-56. Biochar is a soil amendment that can improve soil fertility, increase crop yield and can reduce contamination. This study aim to evaluate the sweet potato response to biochar application from tobacco industry waste. The combination of cultivar and dose of biochar implemented using a Split Plot Experiment Design with three replications. The cultivars placed 0n main plots and biochar doses on sub-plots. The thirteen cultivars covering 7 varieties (Kuningan Putih, Beta 1, Beta 2, Kuningan Merah, Sari, Boko, and Jago) plus six accession from Unitri and Brawijaya University collections (BIS OP-61-OP-22 , 73-6 / 2, 73 OP-8, BIS OP-61, 73 OP-5, and BIS OP-61-?-29). The biochar dose used was B0 (0 t / ha) and B1 (5 t / ha). The experimental unit is measuring 5 m x 0.6 m, consisting of single row and planted with a spacing of 25 cm in row or 20 cuttings/row). The storage root numbers, storage root weight, % dry matter, Harvest Index (HI) and yields estimation are ditermined. The results showed that sweet potato cultivars gave a significant response to biochar application on fresh storage root weight, dry storage root weight, biomass dry weight, HI and storage root yields, but no interaction between cultivars and biochar doses. Storage root yield range of 8 - 21 t / ha without biochar and 10 - 23 t / ha with biochar 5 t / ha, except for Beta 1 and Boko. The use of biochar of 5 t / ha can increase storage root yields ranging from 8 - 45%.
The research was carried out at the CV. Agriranch in Brak Village, Karangploso District, Malang Regency from May until June 2009. Proximate analysis was carried out at the Animal Nutrition Laboratory, Animal husbandry Faculty, Brawijaya University. Objective of this research was to investigate the effect of TDN level in theÂ concentrate for the in vivo digestibility. Â Â Â Â Â Â Â The materials used were : (1) Nine fat-tailed rams with the initial body weight 14 kg: (2) Concentrate (3) Corn stover silage. The experiment used Completely Randomized Design with 3 treatments and 3 replications. The treatments were 3 levels of concentrate: P1 feeding concentrate level TDN 78%; P2 at level TDN 80%; P3 at level TDN 82% (3.12% DM from the body weight) and ad libitum corn stover silage. Variables examined were feed intake and digestibility. The result of the research showed that fat tailed sheep obtaining low TDN concentrate increased feed intake (P<0.05). The highest DM, OM, CP feed intake on the P1 were 97.85 g/kg body weight0.75/day; 85.66Â g/kg body weight0.75/day; 17.59 g/kg body weight0.75/day. Fat tailed sheep obtaining low TDN concentrate its digestibility is lower than those with higher TDN concentrate (P<0.01). The highest DM, OM, CP digestibility on the P3 were 74.65%; 77.99%; 77.23%. Digestible consumption nutrient did not effect (P<0.05) except digestible consumption CP (P<0.01). The highest DM, OM, CP digestible feed intake on the P1 were 66.62 g/kg body weight0.75/day; 63.48 g/kg body weight0.75/day; 13.59 g/kg body weight0.75/day. The conclusion of the research was the increase of the feed intake was intended for fulfilling the energy need. The increase of the feed intake was caused by the increase of forage consumption, so the digestibility decreased. Digestible feed intake was influenced more feed intake than digestibility. Key words : concentrate, energy level, in vivo digestibility, fat-tailed sheep
This trial was aimed to evaluate the performance of sweet potato cultivars on biochar application. The treatments were carried out using a Split-plot Design with three replications. The cultivars were placed on main plots and biochar doses were on sub-plots. The thirteen cultivars consisted of seven varieties and six accessions from Tribhuwana Tunggadewi University and Brawijaya University collections. The applied biochar doses were B0 (0 t/ha) and B1 (5 t/ha). The experimental unit measuring of 5 m x 0.6 m consisted of single row and planted with a spacing of 25 cm in row or 20 cuttings/row. The storage root weight, % dry matter, storage root dry weight, dry weight of biomass, harvest index and yield estimation were determined. The results showed that the sweet potato cultivars gave a significant response to the biochar application on fresh storage root weight, storage root dry weight, biomass dry weight, harvest index and storage root yields, but no interaction between cultivars and biochar doses. Storage root yield ranged from 8 to 21 t/ha without biochar and from 10 to 23 t/ha with 5 t biochar /ha, except for Beta 1 and Boko. The use of 5 t biochar /ha increased storage root yields that ranged from 8 to 45%.
Total Mixed Ration (TMR) is a technology development of silage. The aims of TMR is making feed to keep from microbia, but also contains nutrients to supply nutriens requirement.In the fermentation process have major obstacles in the long ripening. In the long period of the fermentation process which make decrease the nutrient content of feed due to used of feed nutrients by the microbes. TMR research still not optimal so make this research become important to conduct about optimal microbes in the fermentation process of the nutrient content in the manufacture of Total Mixed Ration especially based shoot sugarcane.The method of this research used completely randomized design (CRD) with directional pattern. This research used 2 treatments, the inoculum EM4 (P1) and without inoculum (P0); with the curing time of 0, 7, 14, and 21 days.The results showed that the use of inoculum EM4 in TMR shoot sugarcane can decrease crude fiber content of 29.31% to 24.9% at day 7 compared with the controls, which had decreased on day 21. In the dry matter (BK) there are significantly differences (p

This study aimed to determine the effect of different levels of organic livestock supplements (STO) on banana stem fermentation to physicochemical characteristics including pH, color, shape, texture and odor, dry matter, crude fat. The main ingredients in this study were banana sticks and STO with rice bran as extra material. This study used a Completely Randomized Design (CRD) experiment with 5 treatments and 5 replications and 21 days of ripening. P0: 100% banana stem + 10% without addition of STO, P1: 100% banana stem + 10% rice bran + 0.1% STO, P2: 100% banana stem + rice bran 10% + 0, 2% STO, P3: Banana stem 100% + rice bran 10% + 0.3% STO, P4: 100% banana stem + rice bran 10% + 0, 4% STO. Based on the results of organoleptic test of banana stem fermentation using STO there were no changes in color, texture, odor or shape. Excellent pH treatment was found in P1 with pH 4.0, P0 and P2 with pH 4.1 P3 and P4 pH 4.3 but there was no significant effect between treatments (P>0.05). The nutrient content of dry and crude fat in banana stem fermentation showed very different treatment (P0,05). Kandungan nutrisi bahan kering dan lemak kasar pada fermentasi batang pisang menunjukkan antara perlakuan berbeda sangat nyata (P
