The implementation of Community Forestry (CF) in protected forest area is not only intended to improve welfare of community living around forest but also restores the function of protected areas. This study aims to figure out the types of priority crops that can be developed in CF area based on legal aspect of the rules in protected forest areas and social economic aspect of community surround forest areas. The research was conducted for 4 months, on February – May 2020 in working areas of Meranti Wana Makmur Forest Farmers Group (Gapoktanhut), Lubuk Bintialo Village, Batanghari Leko District, Musi Banyuasin Regency. The result showed that according to provisions of utilization in protected forest areas, the types of crops which developed in the CF area, were multipurpose crops and based on social aspects 5 (five) types of crops that had grown and produced were Rubber, Jackfruit, Djenkol bean, Petai bean, and Durian was in “Fairly Priority” category. Therefore, based on the economic aspect, there were only 4 (four) multipurpose plant types of “profitable” categories, such as Jackfruit, Djenkol bean, Petai bean, and Durian. The type of short-term crops function as companion crops (intercrops) that was good for cultivation were Corn, Chili, Watermelon, and Melon.

Organophosphate pesticides are one of the causes of contamination in animal feed. The cholinesterase enzyme test is used to diagnose toxic exposure due to organophosphate pesticides. Quantitative research with survey design using cross sectional design using 35 samples of cows. The study was conducted in March - September 2020. Concentration measurement on cholinesterase enzyme concentrations of blood plasma used the biosystem A15 DGKC-Colorimetric Kinetic method. This study aims to evaluate the concentration of the enzyme cholinesterase as a marker of organophosphate poisoning in cattle. Blood samples were collected from the ventrolateral neck veins of male and female cattle aged 1-7 years and collected from local cattle in the Ogan Ilir area. The results showed that the cows raised in breeders were exposed to organophosphate pesticides as indicated by a decrease in the concentration and levels of the cholinesterase enzyme in the plasma of female cows. Cholinestrase enzyme levels in female cows were 0.20 ± 0.067 U / ml and bulls were 0.27 ± 0.183 U / ml. The highest concentration of cholinesterase enzyme levels occurred in cows aged 2 years, namely 0.25 ± 0.34 U / ml and the lowest was in cows aged 7 years, namely 0.12 ± 0.04 U / ml.

In this research Concrete mix designs were prepared according to the DOE method and a total of 6 mixes with 72 samples prepared to consist of concrete grade C-25. The test samples were produced with the percentage of substitution for the fine aggregate by 1, 2, 3, 4, and 5% of PET plastic waste aggregate. Moreover, a control mix without replacement for the fine aggregate was used to have a relative analysis. The prepared samples consist of concrete cubes, cylinders, and beams. Furthermore, laboratory experiments were carried out for the prepared concrete test samples. The lists of experiments conducted were; material property, slump, unit weight, compressive strength, splitting tensile strength, and flexural strength tests. The test results were analyzed and compared with the respective conventional concrete characteristics and show that there was a slight increase in compressive strength of the concrete up to 3% replacement and reduction in compressive strength increases beyond 3% replacement due to the replacement of PET aggregates. Also like compressive strength there was an increase of tensile strength recorded with increasing PET bottle aggregate content up to 3% replacement. But more than 3% substitution of fine aggregate with PET bottle fiber results in a reduction in tensile strength, flexural strength. This test result shows that as it is possible to use PET bottles in concrete production as a partial substitution for fine aggregates not more than 3% replacement.

Ayamaru lake is one of the lakes in West Papua categorized as karst lake. It is endowed with fish diversity in various ornamental fish and consumption fish with high economic value. Recently, a number of floating net cages is set up, and before causing serious damage, management for keeping the sustainability of fish resources, especially the endemic species, needs to be proposed. This paper would contribute information on fish diversity and the water quality of Ayamaru Lake. The study was conducted in March, July, and November 2019 at Ayamaru Lake, Maybrat Regency, West Papua Province. The data were collected by conducting direct survey, interviewing the fishers, and the related institution, as well as searching the previous studies. Fish and water samples were taken from five stations. The results showed that 15 freshwater fishes were identified. The capture fisheries were practiced using the environment-friendly fishing gears. The water quality was still quite useful to support fish life. To reduce the threat to the presence of endemic fish in the lake, it needs to regulate the release of introduced species by the community, and control the escaped fish from the culture area.

The dynamic nature of forest habitats is currently influenced by the impact of many disturbing factors, including fire, grazing, area fragmentation, land use conversion and invasion of communities outside forest areas. Fire and smoke from forest and land fires have a profound effect in producing landscape changes that also affect the regeneration of associated vegetation and animals. This study aims to determine the participation of the members of the beekeeper group in preserving the Subanjeriji production forest, in Muara Enim Regency, South Sumatra Province. The research was conducted using a survey method with a qualitative approach. This study also aims to determine the attitudes, knowledge and perceptions of beekeepers on the relationship between beekeeping and forest suistanibility. The results showed that beekeepers known the suistanibility of forest areas that affect the success of beekeeping (80%), so that 60% of beekeepers understand very well that forest and land fires can reduce bee populations and reduce the amount of honey bee. Most breekeepers also understand that the existence of forest plants is very beneficial to support honey production, so that the majority beekeepers are involved in land enrichment efforts with woody plants and most choose Multi Purpose Tree Species (MPTS) plants that produce fruit.

The greatest source of GHG emission from energy sector comes from fossil fuel combustion. Accordingto PLN, 63.75% of electricity distribution in South Sumatra is derived from coal combustion. Coal is a non-renewableenergy source and will deplete in a few decades. The research objective is solving problems related to energyefficiency and GHG emission reduction by reducing electricity consumption in street lighting sector. The researchmethod was carried out through SPSS statistical analysis and LEAP analysis which had been justified based onobservation on the survey results of 1,619 street lighting unit at four distribution areas of Palembang. Theimplementation of electrical energy efficiency is carried out by replacing Son T 250 W lamps into LED lamps withdifferent power. The SPSS statistical analysis determines that 1,000-unit street lightstreet lighting require lightintensity quality of 1,570 lux with correlation coefficient of 0.214. GHG mitigation was conducted in accordancewith convenience and safety standards for road users in which energy efficiency from the replacement of 3,741-unitenergy-saving lamps can reduce GHG emissions by 1,650.9138 tons of CO2e with benefit economic 2,911,481,740rupiahs. In addition, based on LEAP analysis, if 8000 units of LED lamps replace Son T lamps, the electricityconsumption of Street Lighting in 2030 will decrease with a projected efficiency of 17.48%.
