Analysis of Lead (Pb) and Zinc (Zn) Heavy Metal Levels in Coastal Waters of Lemukutan Island, Bengkayang Regency
Get PDFThe waters of Teluk Surau, Lemukutan Island, Bengkayang Regency are part of a Conservation Area that is the center of economic activities such as pearl shell cultivation, fishing, tourist transportation and settlement. These activities have the potential to pollute waters with heavy metals lead (Pb) and zinc (Zn) which can disrupt ecosystems and public health. This study aims to analyze the concentration of heavy metals Pb and Zn based on location characteristics and human activities in the waters. Sampling was conducted at four strategic points representing residential areas, pearl mussel farms, docks and control areas (no activity). Water samples were taken at a depth of 30 cm, then preserved with HNO₃ until pH ≤ 2 and analyzed using Atomic Absorption Spectrophotometry (AAS). The results showed that Pb concentrations ranged from 0.1385-0.1763 mg/L, with the highest concentrations found in residential areas and docks (0.1763 mg/L) and the lowest concentrations in areas without activities (0.1385 mg/L). Zn concentrations ranged from 0.0061-0.0140 mg/L, the highest concentration in the dock area (0.0140 mg/L) and the lowest concentration in the pearl mussel cultivation area (0.0061 mg/L). All sampling locations showed Pb concentrations far exceeded the seawater quality standard for marine tourism (0.005 mg/L) according to Government Regulation No. 22 of 2021 appendix VIII on the Implementation of Environmental Protection and Management, while Zn concentrations were still below the standard
Analisis Faktor-Faktor yang mempengaruhi hasil Produksi Padi di Desa Jangan- Jangan Kecamatan Pujananting Kabupaten Barru
Get PDFThis study aims to analyze the factors affecting rice production in Jangan-Jangan Village, Pujananting District, Barru Regency. The factors examined include land area, labor usage, and pesticide application. Data were collected from 20 farmer respondents through surveys and analyzed using multiple linear regression. The results show that land area and pesticide use have a positive and significant effect on rice production, while labor does not have a significant effect. The coefficient of determination (Adjusted R Square) of 0.679 indicates that 67.9% of the variation in rice production can be explained by the three variables, while the remaining 32.1% is influenced by other factors outside the model. Keywords: rice production, land area, labor, pesticide

Examining Industrialization or Environment Issues: Policy Analysis of Green Land Conversion in Batu City
Get PDFThis research focuses on environmental sustainability which is an important aspect to maintain in sustainable development. The conversion of green land into coffee shops in Batu City has an impact on the local economy, while it hurts environmental sustainability. This research aims to analyze how the policy of the government in the Batu City area is more leaning towards the issue economy or sustainability environment life. This research used a qualitative with approach case studies. Data collection was obtained from two types of data, primary through observations and interviews as well as secondary data through documentation. The study found that there is no local government policy that specifically addresses the conversion of green land into coffee shops, which has a significant negative impact on the environment. Therefore, there needs to be government attention to the environment (environmental governance) through the formulation of environmental policies, mechanisms to support green land investment, and commitment and cooperation of stakeholders to oversee environmental sustainability. Therefore, sustainable development that integrates economic and environmental interests which is required. The conclusion is that no local government policy is in place to deal with the conversion of green land to the coffee shop industry and that the local government policy in Batu City tends to focus on economic issues rather than environmental sustainability

Prospek Ekonomi Peremajaan Perkebunan Kelapa Sawit Rakyat: Analisis Kelayakan di Tingkat Petani, Kabupaten Nagan Raya
Get PDFThis research aims to analyze the financial feasibility and sensitivity of investment in the rejuvenation of smallholder oil palm plantations in Lungmane Village, Kuala Pesisir Subdistrict, Nagan Raya Regency, Aceh Province, amidst the problem of declining Fresh Fruit Bunch (FFB) productivity due to aging trees. The research method used is quantitative analysis with investment criteria of Net Present Value (NPV), Internal Rate of Return (IRR), Net Benefit-Cost Ratio (Net B/C), and Payback Period (PP), as well as sensitivity analysis to changes in FFB prices. The results of the analysis show that the rejuvenation project for smallholder oil palm plantations in Lungmane Village is financially feasible based on positive NPV, IRR, Net B/C, and Payback Period indicators. However, the sensitivity analysis reveals that the project's feasibility is highly influenced by fluctuations in FFB prices, where a price decrease of up to 70% can render the project unfeasible. This study concludes that although the rejuvenation of smallholder oil palm plantations in Lungmane Village has good financial prospects, farmers need to be aware of the risk of declining FFB prices
Peningkatan Kualitas Throat Weld pada Hasil Penetrasi Produk Bracket Spring dengan Metode DMAIC di Perusahaan Komponen Otomotif
Get PDFComponent Automotive Indutry is a manufacturing company that focuses on making chassis frames and press parts, with the production delivered to ATPM (Single Agent Brand Holder) customers. One of the production lines at Component Automotive Indutry is the non-frame sub-assembly using welding robot A, which produces various components, such as spring bracket no. 1, spring bracket no. 2, spring bracket no. 3, and engine mounting bracket. To ensure welding quality, Component Automotive Indutry conducts various tests, including welding penetration tests, which are carried out in the company's laboratory using samples in accordance with the Quality Control Process Chart (QCPC). Over the past three months, the penetration test results on the spring no. 1 bracket showed a penetration rate of 82%, which did not meet the ATPM company's minimum standard of 100%. Faced with this problem, this study uses the DMAIC (Define, Measure, Analyze, Improve, Control) method to conduct process analysis and improvement. In the Define stage, the main problem identified was item throat penetration that did not meet the standard. The Measure stage then set a target of 100% penetration improvement. In the Analyze stage, the main causes of penetration instability were analyzed, identifying the vertical welding position as the main causal factor. The Improve stage was carried out by changing the welding position of the throat item from vertical to horizontal using a temporary jig. This change aimed to maintain gravity stability and achieve consistent penetration in accordance with the minimum standard of 4.2 mm. After conducting 9 trials, the improvement results showed that the welding penetration achieved 100% stability. The Control phase ensured that the implemented changes were continuously maintained to ensure consistent quality. This study concludes that changing the welding position from vertical to horizontal is significant in improving the quality and consistency of weld penetration on bracket spring no. 1 products at Component Automotive Indutry The findings underscore the importance of evaluating and adjusting the welding process to meet the quality standards set by customers
