Abstract

The dependence on imports of feed ingredients for ration composer are increasingly expensive and availability of limited and unsustainable local feed, causing the low level of production and reproduction of local Indonesian cattle. This study aims to exploit the potential of plantation waste as an alternative feed of beef cattle, increase the nutrient value and digestibility of waste of palms and leaves and to know the optimal use of inoculums (Trichoderma sp.) through fermentation in improving the digestibility and nutritional value of the feed. The research method used was a complete randomized design (RAL) with five treatments and three replications, with 14 days fermentation. The research treatment includes: PD 0 (without Trichoderma/control), PD 1 (fermentation using Trichoderma viride 3 ml), PD 2 (fermentation using Trichoderma viride 6 ml), PD 3 (fermentation using Trichoderma harzianum 3 ml), PD 4 (fermentation using Trichoderma harzianum 6 ml).O Observation parameters observed included dry matter (DM), crude protein (CP), ash content (AC), coarse fat (CF), organic matter (OM), and total digestible nutrient (TDN). The data obtained were analyzed using variance analysis. The results showed that the best treatment was found in PD 1, had a significant effect on control in increasing total digestible nutrient (TDN) 51.62% and crude fiber decline by 39.14%, although an increase in CP (5.34%) was not equal to the treatment of the PD 4 (5.35%). While the best increase of CP content was found in the treatment of PD 4 of 3.35%. While the best CP content found in the treatment of PD 4 of 5.35%. It was concluded that the use of Trichoderma viride and Trichoderma harzianum can improve the quality of waste nutrient and palm oil leaves by fermentation and the optimal inoculums dose used to produce the best fermentation is the use of Trichoderma sp. 3 ml in 3kg of material.

Abstract

Mechanism process and work activity  tyre unit in PT. Rahman Abdijaya workshop using machines and working equipments. Noise with high intensity of those machines and working equipments will raise noise exposure and will increase the risk of the worker.  This study aims to analysis affect of noise to hearing function and blood pressure at tyre worker in workshop PT. Rahman Abdijaya   in  Tabalong district.  It is an observational study with cross-sectional design. Sample size was 32 worker. Data collection by audiometric  measurement, tension before and after working measurement also noise in working environment measurement. Univariat analysis, bivariat analysis. With chi-square test are used to analyzed the data. The results of the study showed that there was not significant affect of noise to hearing function (sig.α = 0,401 > 0,05), but there was significant affect of noise to sistole blood pressure (sig.α = 0,039 < 0,05) and diastole blood pressure (sig.α = 0,019 < 0,05). Suggestion for the company are necessary noise measurement in all working company area, maintenance activity must be done for periodically and all of broken equipment must be replaced, audiometric measurement every ones in a year, blood pressure measurement must be controlled, Safety sign compatible as safety and health risk, prepared APD like ear muff, training  and socialized about noise affect to the health and how to control them.

Abstract

 This study aims to analyze Resources potentials (R), Organizations (O) and Norm (N) conservation center of Adang Bay nature reserve and village conservations area and formulate management model of Adang Bay nature reserve in the effort of conservation of environmental resources in Paser Regency of East Kalimantan.    The research was conducted in eight villages with in Adang Bay reserve area (Padang Pangrapat village, Pondong Baru village, Pasir Mayang village, Muara Adang village, Air Mati village, Teluk Waru village, Muara Telake village, and Petiku village) the study was conducted in May to September 2016. The analysis used was qualitative descriptive with data collection methods by triangulation in – depth interview, observation, and FGD, researchers information were selected by the purposive method.    The result of this research is to know the potential of resources contained in Adang Bay Nature reserve area of 18.956 Ha of mangrove area, community resources that live in the area as many as 14.767 people and Adang bay areas are very suitable for aquaculture of fish pond and shrimp, and the high spirit of community mutual corporation in eight conservation village, the Adang Bay Nature Reserve consist of eight definitive villages so that 30 % empowerment budget is available, as well as BUMDes that can be collaborated as a conservation village promotion effort.    Adang Bay Nature Reserve Management Model that supports is Collaborative Management Model, with this model the existence of Adang Bay Reserve does not change the status of the area. The management program stages are directed to protection, preservasion, and utilization with consideration of social, economy and ecology in Adang Bay area.

Abstract

Tofu industry produces organic waste that can decrease the quality of the environment. The alternative processing method can be used among others is activated sludge system, but several types of research have not shown optimal results yet. To improve the quality of wastewater, the treatment of wastewater of tofu using activated charcoal needs to be done. The purpose of this research is to analyze the effects of the ironwood charcoal activation on the morphology and surface area of  ironwood activated charcoal, to analyze the effects of variations in the flow rate of tofu wastewater effluent from activated sludge using ironwood activated charcoal on the parameters of temperature, pH, TSS, BOD, COD and ammonia and to find out the optimum flow rate of tofu wastewater effluent from activated sludge using ironwood activated charcoal. This research used adsorption method with column system at 7 treatments of flow rate (50, 60, 70, 80, 90, 100 and 110 mL/h) with 3 replications. The activation of ironwood charcoal used Na2CO3 5% and was activated at 400oC. The results showed that the surface morphology of ironwood active charcoal had more open pore surfaces with more regular structures than before activation. The surface area of ironwood activated charcoal was 32.936 m2/g and increased to 53.7% compared with it before activation. Variations in the flow rate on the tofu wastewater effluent from activated sludge using ironwood activated charcoal showed highly significant (p < 0.01) in reducing the levels of TSS, BOD, COD, and ammonia. The optimum flow rate obtained at 50 mL/h with temperature was 25.8oC, pH 8.08, TSS 34.7 mg/L, BOD 43.8 mg/L, COD 117 mg/L and ammonia 14.8 mg/L. The value of temperature, pH, TSS and BOD have fulfilled the quality standards, the quality of tofu wastewater effluent increased from the activated sludge.
