Abstract

Dusun Sinar Laut merupakan salah satu wilayah di Desa Sidomekar, Kecamatan Katibung, Lampung Selatan yang memiliki penambangan tanpa izin (PETI). Adapun mineral yang ditambang yakni emas. Saat terjadinya penangkapan terhadap 4 (empat) penambang tanpa izin di dusun tersebut oleh Aparat Penegak Hukum (APH) ditemukan 18 besi tabung gelondongan yang diduga merupakan bahan berbahaya jenis merkuri yang digunakan untuk mengolah emas di lokasi tersebut. Penggunaan merkuri dalam mengolah hasil tambang saat ini telah dilarang di Indonesia karena bahaya yang dapat ditimbulkan, baik bagi penambang, lingkungan, maupun kesehatan masyarakat sekitar. Pengabdian Kepada Masyarakat ini bertujuan untuk meningkatkan pengetahuan dan pemahaman masyarakat terhadap peraturan yang berlaku ketika melakukan aktivitas penambangan serta dampak buruk menggunakan bahan berbahaya dalam pengolahan hasil tambang. Peningkatan pengetahuan dan pemahaman tersebut dilakukan melalui sosialisasi serta edukasi kepada masyarakat. Kegiatan ini mengundang pemangku kepentingan terkait, seperti aparat Desa Sidomekar, para Kepala Dusun, serta masyarakat di desa tersebut. Dengan adanya Pengabdian Kepada Masyarakat ini masyarakat Dusun Sinar Laut lebih memahami mengenai tata cara pengajuan izin dan peraturan yang berlaku terkait dengan aktivitas penambangan. Selain itu masyarakat juga dapat mengetahui cara mengolah emas yang baik dan bahaya dari penggunaan merkuri dalam pengolahan emas. Hal ini dapat dilihat dari terjadinya peningkatan pemahaman dan pengetahuan warga terhadap penambangan tanpa izin (PETI) dan bahaya penggunaan merkuri yakni sebesar >20% pada indikator mengetahui dan sangat mengetahui, serta indikator sangat tidak mengetahui turun dipersentase 0%. ABSTRACT Sinar Laut Hamlet is one of the areas in Sidomekar Village, Katibung Subdistrict, South Lampung that has unlicensed mining (PETI). The mineral being mined is gold. During the arrest of 4 (four) unlicensed miners in the hamlet by Law Enforcement Officials (APH), 18 iron tubes were found, which were suspected to be hazardous materials such as mercury used to process gold at that location. The use of mercury in processing mining products has now been banned in Indonesia because of the dangers it can cause, both for miners, the environment, and the health of the surrounding community. This “Pengabdian Kepada Masyarakat” aims to increase community knowledge and understanding of the regulations that apply when conducting mining activities and the adverse effects of using hazardous materials in processing mining products. Increasing knowledge and understanding is done through socialization and education to the community. This activity invited relevant stakeholders, such as Sidomekar Village officials, the Heads of Hamlets, and the community in the village. With this “Pengabdian Kepada Masyarakat”, the people of Sinar Laut Hamlet have a better understanding of the procedures for applying for permits and applicable regulations related to mining activities. Apart from that, the community can also find out how to process gold properly and the dangers of using mercury in gold processing. This can be seen from the increase in residents' understanding and knowledge of unlicensed mining (PETI) and the dangers of using mercury, which is> 20% in the indicator of knowing and very knowing, and the indicator of very not knowing dropped to a percentage of 0%. Keywords: Mining, mercury, gold mines, best practice mining.

Abstract

Marine clay land is formed due to hydrological factors, including acidity, low macronutrient levels, relatively high micronutrient levels, and a clay-dominant texture. Land improvement for marine clay land is necessary to enhance plant growth and productivity. Eucalyptus pellita is a plant that is adaptive to various types of land and is used as a raw material for pulp and paper, which is widely cultivated in Industrial Plantation Forest (HTI) in Indonesia. Research is needed to enhance the quality of marine clay soils and promote plant growth. Land quality can be improved by adding soil ameliorants from surrounding waste, such as waste from HTI, specifically pulp and paper sludge (KCa). This study used a combination of organic ameliorants (cocopeat and cattle manure) and inorganic (KCa, KCl, and dolomite), using a factorial complete random design consisting of two factors. The first factor was inorganic ameliorants, which consisted of four levels: A0 (no inorganic ameliorant), A1 (KCa 25 g), A2 (KCl 25 g), and A3 (dolomite 25 g). The second factor is organic ameliorants, which consists of 7 levels: B0 (no organic ameliorant); B1 (cocopeat 200 g); B2 (cocopeat 100 g); B3 (cocopeat 50 g); B4 (cattle manure 200 g); B5 (cattle manure 100 g); and B6 (cattle manure 50 g). The interaction of these two treatment factors resulted in 28 treatment combinations. A total of 1 kg of sterilized marine clay soil was placed in a polybag, then ameliorants were added according to the experimental design. The purpose of this study is to utilize HTI industrial waste as a soil ameliorant and to analyze the optimal dose of the ameliorant used during the study. The results of this study indicate that improving the quality of marine clay soil using a combination of organic and inorganic ameliorants enhances the growth in height and diameter of E. pellita compared to treatments using single ameliorants. The results showed that the treatment with B2A1 (Cocopeat 100 g and KCa 25 g) was the most effective, yielding the highest growth response, diameter, and number of leaves compared to other treatments.
