Peran Polisi Kehutanan Dalam Menanggulani Kegiatan Illegal Logging Di Taman Nasional Alas Purwo

Eko Setiawan — 2024-06-01

Alas Purwo National Park has a variety of potential unique biodiversity and ecosystems, making it important in creating a sustainable relationship with the environment. Threats to the sustainability of conservation areas, one of which comes from illegal logging activities that have been categorized as extraordinary crimes. This article aims to answer problems related to illegal logging, the role of the Forestry Police and its obstacles in tackling illegal logging activities in Alas Purwo National Park. This research uses a qualitative approach in the form of a case study. Data collection methods by observation, in-depth interviews, documentation. Data analysis using interactive models, including the stages of data collection, data reduction, data presentation and conclusions.Various efforts have been made by the Forestry Police to tackle illegal logging activities, but there are still obstacles on the ground. Therefore, this article is expected to be a contribution of thought for policy makers, both at the regional and central levels.

Analysis Of Hexavalent Chromium Metal Content Of River Water By Flame Atomic Absorption Spectrophotometer

Atina Atina — 2024-06-01

Population growth and intensified human activities have resulted in global environmental conditions experiencing increased risks to water quality. One of the serious threats to water quality is heavy metal contamination, including hexavalent chromium metal (Cr-VI). This study aims to analyze the levels of hexavalent chromium metal (Cr-VI) in river water with an analytical method that is in accordance with SNI 6989.53: 2010, the test method using an atomic absorption spectrometer (SSA)-Nyala. Based on the analysis that has been done on 2 samples (sample A and sample B), the value of hexavalent chromium levels in sample A is 0.035 mg/L and sample B is 0.0127 mg/L. So that the results can be stated that the hexavalent chromium (Cr-VI) levels in the river water are still below the quality standards based on PP RI No. 22 of 2021 concerning the Implementation of Environmental Protection and Management so that it is categorized as safe.

Helfa Septinar — 2024-06-01

Organic waste is waste that comes from plants and creatures; if not managed properly, it will produce methane gas, which can damage life on earth. One type of organic waste is fruit peel waste. The aim of this research is to recycle organic fruit peel waste into eco-enzymes and test the levels of eco-enzyme macro nutrients. The method used is laboratory testing with spectrophotometric and absorbance tests. The research results were pH 3.5, N 526 mg/l, P 4.2 mg/l and K 2,900 mg/l.

Uji Padatan Tersuspensi Total (TSS) Pada Sampel Air Limbah Sawit Secara Gravimetri

M. Hapiz Hermansyah — 2024-06-01

Palm oil liquid waste is a pollutant that has the potential to cause negative effects on the environment. This industrial waste is known to cause pollution, especially in water bodies. Through analysis of the chemical composition of TSS, the type of solid material dissolved in liquid waste can be identified. Gravimetry is an examination of the amount of a substance by weighing the results of the precipitation reaction. This research aims to determine the amount of suspended solids in palm oil wastewater using the gravimetric method. Based on the analysis that has been carried out, the highest Total Suspended Solid (TSS) value was obtained for sample A, namely 15.274 mg/L, sample B, namely 58.2 mg/L and sample C 57.1 mg/L. So the results can be stated that the Total Suspended Solid (TSS) value in palm oil wastewater is still below the quality standards contained in the Minister of Environment Regulation No. 05 of 2014.

Pemanfaatan Limbah Tandan Kosong Kelapa Sawit Menjadi Pupuk Kompos Di Desa Suka Damai Kecamatan Tunggal Jaya Musi Banyuasin

Ita Emilia — 2024-06-01

Processing palm oil into palm oil produces solid waste in the form of empty palm fruit bunches (TKKS) which will cause environmental pollution. The aim of this research is to find out how to manage waste from empty oil palm fruit bunches into compost which is needed by plants as a natural nutrient. The research method uses experimental methods. The results of the research resulted in TKKS being able to be processed into compost by fermentation.
