Abstract

The physical and chemical environmental impact in a mining area is inevitable, particularly for open pit mining areas. The impact could affect soil and water quality where mining activities, such as land clearing, blasting and hauling, occur. Thus, environmental monitoring in mining areas should be taken to measure the impact of mining activity for reclamation purposes. The objective of this research focuses on the measure of environmental impact on soil quality in terms of the nutrient content in an abandoned mine area at Jantang village, Lhoong, Aceh Besar. The research was conducted by collecting 15 soil samples, followed by laboratory analysis using atomic absorption spectrophotometry to investigate sampled 'soil's nutrients which are pH, Carbon (C-organic), Nitrogen (N-total), Phosphor (P-availability), and Ferro substance (Fe-concentration). In addition, to estimate the soil properties at locations outside the sampling area, a spatial interpolation method called inverse distance weight with an optimum power was used. The result shows that the soil is acidic, with low C-organic in the range of 0.02%1.84%, N-total 0.02%0.16%, and P-availability 0.55%3.75%. In contrast, the Fe-concentration is very high, at 30003400 ppm.

Abstract

This study aims to analyze the influence of communication, job satisfaction, and organizational culture on employee performance at the Medan Amplas Sub-district Office. The research used a quantitative method with a survey approach, involving 50 respondents. The data were analyzed using multiple linear regression. The results of the study show that communication, job satisfaction, and organizational culture partially and simultaneously have a significant effect on employee performance. Communication has the greatest influence compared to other variables. The determination coefficient shows that 75.4% of the variation in employee performance can be explained by these three variables. The implications of this study emphasize the importance of improving the quality of communication, job satisfaction, and organizational culture in order to improve employee performance in the government environment.

Abstract

Pemanfaatan limbah organik sebagai sumber energi alternatif menjadi solusi yang penting dalam menghadapi permasalahan limbah dan ketergantungan terhadap bahan bakar fosil. Desa Cot Mesjid, Kecamatan Sukamakmur, Aceh Besar, memiliki potensi besar dalam pengelolaan sampah organik yang dapat diolah menjadi biobriket sebagai sumber bahan bakar alternatif. Program pengabdian masyarakat ini bertujuan untuk mengidentifikasi potensi limbah organik, memberikan pelatihan pembuatan biobriket, serta menganalisis manfaat lingkungan dan ekonomi dari pemanfaatan biobriket. Metode pelaksanaan terdiri dari tahapan sosialisasi, identifikasi bahan baku, pelatihan produksi biobriket, serta monitoring dan evaluasi efektivitas penggunaan biobriket. Pelatihan dilakukan dengan pendekatan praktik langsung, melibatkan masyarakat dalam setiap tahap produksi mulai dari pengumpulan bahan baku, proses pirolisis, penghalusan arang, pencampuran dengan bahan perekat, pencetakan, hingga pengeringan biobriket. Evaluasi dilakukan melalui observasi, wawancara, dan angket kepada peserta pelatihan. Hasil menunjukkan bahwa masyarakat merespons positif program ini, dengan peningkatan pemahaman mengenai pemanfaatan limbah organik dan kemampuan produksi biobriket secara mandiri. Selain itu, biobriket yang dihasilkan memiliki efisiensi pembakaran yang tinggi dan dapat mengurangi ketergantungan terhadap bahan bakar fosil. Potensi pengembangan usaha biobriket juga terlihat dari minat beberapa kelompok masyarakat dalam memasarkan produk ini secara lokal. Dengan hasil yang positif, program ini dapat menjadi model bagi daerah lain dalam mengembangkan pemanfaatan limbah organik sebagai sumber energi alternatif yang ekonomis dan ramah lingkungan.

Abstract

The large amount of liquid waste generated from urban activities can provide negative impacts, such as disease spread, environmental damage, and others. Therefore, treatment efforts before disposal into the environmental are crucial. One method of treating liquid waste that can be used is the trickling filter. The trickling filter method used in this research utilizes natural fibers, namely coconut fiber, as the packing media, replacing sand or plastic as the packing media in conventional trickling filters. Treatment of municipal liquid waste (domestic waste) using coconut fiber trickling filters is one application of biofilm technology in wastewater treatment, where a biological layer (biofilm) like mucus will grow on the surface of the media. This biological layer will meet the wastewater and degrade the pollutant compounds presentin the wastewater, resulting in water with lower biological oxygen demand (BOD) values than before. Theresult if water that is safe for disposal into the environment. This trickling filter reactor can degrade pollutants with degradation efficiency of BOD 91.3%, nitrate 50.25%, and ammonia 37.5% at the optimal flow rate of this study (0.256 L/min).

Abstract

Gampong Alue Peuno, Bireuen, us a region in Aceh known for its rich petroleum resources. This abundance has led to many oil wells being freely managed by the local community. This study aims to analyze water quality in Gampong Alue Peuno according to established water quality standards, utilizing the Pollution Index method in reference to the Indonesian Minister of Environment Decree No. 115 of 2003. The Pollution Index assesses water quality across ten points, considering parameters such as pH, temperature, oil and fat, TDS, BOD, COD, and DO. Water quality calculations for Gampong Alue Peuno yielded Pollution Index (IP) values at points 1 through 10 of 2.423, 3.505, 2.022, 2.534, 2.241, 2.328, 1.847, 3.180, 4.370, 1nd 1.510, respectively. Based on Decree No. 115 of 2003, all teat points fall into the light pollution category (1.0 < IP < 5.0 for Class II water quality standards. Water in Class II with light pollution is not recommended for daily activities such as washing dishes, washing clothes, bathing, irrigating plants, and livestock care, or other needs requiring similar water quality. Polluted water usage can directly or indirectly affect public health and harm aquatic ecosystems.

Abstract

In this technological era, minerals, in an educational context, refer to components that contribute to overall educational success. Mineral resources serve as the basis for various industries, such as construction, manufacturing, technology, and energy production. This community service activity aims to strengthen the science of high school students at SMP Negeri 6 Banda Aceh so that it can explain the contribution of mineral resources to a country’s Gross Domestic Product. The service team plays a role in providing knowledge of mineral resources to students so that in the future they can develop a basic understanding of earth science. This science strengthening allows students to learn about the formation, properties, and classification of minerals, which are basic concepts in geosciences. The method used is lecture method, question and answer, discussion, and demonstration. The students showed an enthusiastic response to the material presented and participated in the discussion with pleasure.
