  Background and Objective: The dominant content of crude fibre is cellulose and if it is used as a feed ingredient, cellulase enzyme must be added. The aim of this research was to investigate the effect of using sago waste with cellulase enzyme as a local feed ingredient on the production performance of broiler chickens. Materials and Methods: Three hundred Day Old Chickens (DOC) broiler strain CP 707 were kept in enclosed litter cages. There were 30 cage plots. The size of each plot was (1×1) m2. The cage wall was made of metal. The wall height was 0.5 m. Each plot was equipped with a feeding and drinking container. There were10 DOC broilers in every plot with six replications. The treatment for this research was sago waste with cellulase enzyme at 0.75 g kg–1 sago waste. The sago waste is added at levels of 0.00, 5.00, 10.00, 15.00 and 20.00% of total feed. The variables measured in this research were feed consumption, body weight gain, feed conversion, the abdominal fat weight, the percentage of abdominal fat and fatty meat. The data were analyzed by using a one-way ANOVA with a Completely Randomized Design and if there was a difference between treatments (p<0.05), Duncan’s New Multiple Range Test (DMRT) was used. Results: The results of this research show that the addition of sago waste with cellulase enzyme in the feed did not significantly influence consumption and fat content of the meat of 35 days old broiler chickens but did significantly influence body weight gain, feed conversion, the weight of abdominal fat and percentage of abdominal fat of 35 days old broiler chickens (p<0.05). Conclusion: Sago waste with cellulase enzyme as a broiler feed ingredient can improve body weight gain as well as decrease feed conversion, the weight of abdominal fat and the percentage of abdominal fat. It is more effective if it is used at a level of 15% of total broiler feed and it does not have a negative effect on feed consumption and fat content of 35 days old broiler chicken meat.

  Objective: The purpose of this study is to determine the amount of cellulase enzyme needed to optimize sago palm waste feed digestibility in vitro . This information can provide the basis for use of sago palm waste in broiler chicken feed. Methodology: Cellulase was added to the sago palm waste feed material at 5 different concentrations and five trials were conducted for each feed mixture. The parameters measured in this study were: in vitro dry matter digestibility (IVDMD), in vitro organic matter digestibility (IVOMD) and in vitro crude protein digestibility (IVCPD). The metabolic energy, crude fiber and cellulose contents in sago palm waste were also determined. The resulting data were analyzed statistically with a directional completely randomized design. Results: Sago palm waste with cellulase added to 0.75 g cellulase kg–1 waste had the best IVDMD (35.94 vs 19.32% for 0 g cellulase) and IVOMD (35.25 vs 19.32% for 0 g cellulase) values. Optimal values for the crude fiber and cellulose content were also seen for 0.75 g cellulase kg–1 waste with a maximum reduction to 12.79% crude fiber content (decreased by 23.69% compared to untreated waste) and 7.91% cellulose content (decreased by 29.56% relative to untreated waste). The crude protein digestibility and sago palm waste metabolic energy content at various cellulase concentrations were similar but 0.75 g cellulose kg–1 sago palm waste produced optimal crude protein digestibility and metabolism content. Conclusion: Addition of cellulase enzyme to sago palm waste at 0.75 g cellulose kg–1 sago palm waste improves IVDMD and IVOMD. This amount of cellulase also produced the best crude fiber and cellulose contents. Together these results suggest that cellulase can be used to improve the qualities of sago palm waste as a feed for broiler chickens.

  The main purpose of this study was to give application and socialization to coconut farmers community about integrated technology in cultivating coconut products through oven drying copra by sand tank system; this is cultivating technology of high quality of coconut oil and coconut charcoal. Specifically, this study was aimed to implement appropriate technology in cultivating white copra by using fireproof furnace break. Technique of this article using socialization and simulation the application of appropriate technology with target communities was coconut farmer’s community in Pohorua village of Muna Regency which consists of village officers, coconut farmers and house wife. The result of application and socialization of introduction technology appropriate in drying white copra was coconut farmers were easier to understand technology of cultivating white copra by using fireproof furnace break compared to technology appropriate oven drying copra by sand tank system as heat grading because the material were easy to find and can be made by community itself, simple to make and production price was more expensive. Next, socialization of quality coconut oil cultivation technology by fermentation technique was farmer’s community was easy to understand the fermentation process and incubation compared to process of making coconut milk cream because market of production is access table, durable and simpler to make. Introduction of cultivating technology of coconut charcoal by tank technique is proper to be implemented and got positive response from coconut farmers because so far coconut shell was just waste. Result of appropriate technology of drying or cultivating white copra by using furnace break fire prof can increase farmer’s income because the price is more expensive that is IDR 12.000/kg while price of black copra as cultivated by farmer’s community is only IDR 4.500/kg. In addition, conventional drying construction was easy to be bunted because it is made of wooden board and copra produced still smelled of smoke.
