Bukit Rimbang Bukit Baling Wildlife Reserve (BRBB) was designated in 1982 and was established in 2014 based on the Decree of the Minister of Forestry SK Number. 3977 / Menhut-VIII / KUH / 2014 dated May 23, 2014 covering an area of 141,226.25 ha in Kampar Regency and Kuantan Singingi Regency, Riau Province. The aim of this study was find out about local community knowledge in the Wildlife Conservation Area (BRBB) about kelulut or stingless bee (Trigona spp.) cultivation and to know the relationship between the respondent characteristics with that knowledge. This method of this research was quantitative approaches. The number of respondents was 85 people, selected based on random sampling spread in Koto Lamo Village, Bukit Betung Village, and Tanjung Belit Selatan Village. Data were analyzed statistically by chi-square test. The results of this study show that the local community has knowledge about stingless bee cultivation at the “knowing” level. Individual factors that were significantly related to people's knowledge of stingless bee cultivation were gender, employment, and education

Wastewater is a residual from detergents usage that has negative impact to the environment, such as aquatic biota toxid. The Model of aquatic biota mortality as a function of detention time for the wastewater detergent concentration was eliminated by secondary data. Model is selected by election of trendline type that have highest determination coefficient, while simple idea of the detergent pollution control technique was analized from previous research and some other aspect. Result showed that aquatic biota mortality with perception time can be expressed with second order polynominal model. Damage of the vital aquatic biota organ such as cell membran, liver and heart, and also water quality degradation is allegedly caused of organisms mortality as a due to detergent increased in water bodies. A very high detergent concentration, is endangering biota in water bodies. Usage of environmentally friendy detergens, and also wastewater treatment for detergent before entering the water bodies, is expected to protecting more aquatic biota so that ecosystem can maintained. Individual detergent screening technique (TPDI) idea expected acceptable and exploted by public as one of the detergent pollution control.

Gedebage Reservoir is built as retention ponds, in the future it will be developed into an integrated religious tourism area, so that the quality of water reservoir must suitable for tourism. Constructed floating wetland with mooring system, besides being used as water quality improvement technology, it will also add aesthetic value. The purpose of this study was to identify the possibility of applying the constructed floating wetland in the Gedebage Reservoir area. This study uses secondary data to determine the design parameters and characteristics of water sources, design parameters are used for location recommendations, while the characteristics of water sources are to determine the accuracy of the technology used. The result shows that the placement of a floating wetland technology with mooring system in Gedebage reservoir has meets the requirements of design parameters than in a biological filter channel. The characteristics of the Gedebage Reservoir water source that have not met requirements consist of several parameters, namely: Ammonia, Chlorine, Mn, DO, Sulfide, Detergent, Oil and Fat, Cd, Pb, DO, BOD, COD, Fecal Coliform and Total Coliform. Whereas, based on the ratio of BOD5 / COD in the dry season that ranged from 0.25 indicating that the water had been toxin, so that it would disrupt the development of biofilms, so in addition to wetland, a pre-treatment was needed before entering the reservoir.

Since 2014 offshore un-manned gas platforms near Mahakam Delta have been used by hundreds of egrets sleeping/roosting sites, causing nuisance. The objective of the research was to formulate a management plan in general and to plan a functional construction design to modify the existing construction in order to control the bird nuisance. Field visits were conducted in August 2019 and February 2020 to the gas platform complex (i.e. Dx, TMP-2, D), focusing on Dx Platform, of which its operation will be terminated soon. Basically, Dx Platform will be modified as egret’s roosting site. Attractants need to be constructed on Dx Platform, while deterrents should be placed on other adjacent platforms (D and TMP-2). Some suggested attractants are appropriate perch-sites, construction of cover (from strong sea-wind), provision of twigs and branches as nest material, as well as the provision of shallow water and food (fish). Suggestions for deterrents on other platforms are spikes, wire, and some other innovative mechanical/physical devices, and all are tailor-made for platforms. In addition to the Dx Platform modification, in the long term, the root cause of the bird nuisance needs to be tackled, namely the restoration of Mahakam Delta from excessive fish/shrimp ponds development.
