Abstract

Sungai Masang Kecil is located in the middle of the PT Andalas Agro Industri (PT AAI) palm oil plantation and mill. This activity will have an impact on aquatic biota, especially benthos. Benthos occupies an important position in the food chain and lives permanently on the substrate to be used as a bioindicator of pollution. This study aimed to determine the Community Structure of Macrozoobenthos and the indicator species of water pollution in the Masang Kecil River around the PT AAI area, West Pasaman Regency. This research was conducted using a purposive sampling method with three sampling points, namely upstream and two downstream points after the Wastewater Treatment Plant (IPAL) and after the confluence of tributaries. Sampling using Surber net size 30 x 30 cm. The results of identifying the types of Bento's organisms as a whole identified as many as 45 species. Most species are found in Class Insecta. Based on the diversity index, the water quality in PT AAI's river basin was classified as unpolluted, and it could be concluded that the benthic condition was in good condition on a scale of 4. In the current study, the Diptera order as an indicator of polluted water was most commonly found among orders from other insect classes, namely, ten species. However, there were nine species from the Order Ephemeroptera as an indicator of clean waters and six species for Trichoptera.

Abstract

The efforts to reduce production costs to minimize feed costs, so that farmers can benefit from livestock business. One way to meet the availability of feed ingredients quality and quantity as feed animal. The materials and tools used in this study were gambir extraction waste, local microorganism, rice washing water, fine bran, rumen microbes, Mc Dougall buffer solution, fermentation rack, salt, brown sugar, plastic and a set of tools for in-vitro testing. The study was conducted experimentally with a 3x4 factorial Randomized Block Design pattern with two replications for each treatment combination. Based on statistical analysis, it was shown that the use of bran and fermentation time had an insignificant (P>0.05) effect on Crude Protein (CP) degradation in the rumen in vitro and a very significant (P<0.01) effect on NH3 production, Crude Fiber (CF) Degradation and volatile fatty acid Production. The results of study was that leg fermented with local microorganisms showed no significant difference in CP degradation, while NH3 production. CF degradation and volatile fatty acid production increased from leg fermented with local microorganisms without the addition of bran, so it could be used as feed ruminant.

Abstract

The waste of peel coffee was potential to be used as feed animal because it is rich in nutritional quality for livestock needs. The Purpose of this study consist of: 1) Developing biotechnology and innovation of feed made from coffee peel waste as an alternative feed to support agro-industry, 2) Utilization of appropriate local raw material innovations as quality feed animal to increasing the nutritional value, growth and production of livestock; 3) Reduce the cost of forage substitution feed production using coffee rind as feed animal.Observation and collection of quality coffee peel waste, 2) Preparation and manufacture of fermenters, 3) Processing and manufacturing of fermented coffee peel waste feed additives, 4) Analysis of the nutritional quality of coffee peel waste using several fermenters. The results of the study using mixed coffee peel + local microrganism of the tempeh yeast is very significant and has a high nutrient content, much higher than other fermenters when viewed from dry matter 88.1%, crude protein 27.20%, crude fat 16.90%, Total Digestible Nutrient (TDN) 72.50%, and Crude Fiber decreased by 15.60%. The results of the study using coffee peel waste were alternative to the feed animal to support agro-industry it can be concluded fermenters using mixed coffee peel + local microorganism tempeh yeast have a high content when viewed from dry matter 88.1%, Crude Protein 27.20 %, Crude Fat 16.90%, TDN 72.50%, and Crude Fiber decreased by 15.60%.
