Abstract

Diagenetic studies observe the process of changing sedimentary deposits into sedimentary rocks. This study is critical because it relates to the quality of rock porosity, which can be filled by fluid.  The analysis of the Peunasu Formation is interesting because previous researchers considered that the Tertiary sedimentary rocks in the Northwest Aceh Basin are equivalent to rock units in the petroleum system in the North Sumatra Basin and Mergui Basin. Meanwhile, studies on the Peunasu Formation, a tertiary sedimentary rock, still need to be completed. Therefore, this study was carried out to determine the characteristics and diagenetic processes in the sandstone of the Peunasu Formation. The method used is petrographic observation, which identifies the composition of rocks along with textures such as grain size, roundness, sorting, grain contact, and porosity. The results are that the Peunasu Formation sandstone is classified as sublitharenite, lithic greywacke, and litharenite. The diagenetic regime is mesogenesis. In the mesogenesis stage, the sandstone of the Peunasu Formation experiences compaction, cementation, and dissolution. The porosity of the Peunasu Formation sandstone, as determined by the percentage of pores, exhibits a range of 0.5% to 16.8%, categorizing it as ranging from negligible to moderate. Compaction reduces the intergranular porosity, while the dissolution of grains contributes to the formation of secondary porosity.

Abstract

Patchouli oil and citronella oil are Aceh’s leading commodities that produce essential oils with various benefits, including natural antibacterial properties. However, their utilization in household products remains limited, while most communities still rely on chemically based floor cleaners at relatively high prices. In response to this potential, a community service program was conducted in Pango Deah Village by empowering beneficiaries of the Family Hope Program (PKH) to innovate in producing antibacterial floor cleaning soap based on patchouli and citronella oils. The activities included socialization on household hygiene, technical training on soap production, hands-on practice through a learning-by-doing approach, and evaluation using pre-test and post-test assessments. The evaluation results showed an increase in the average score from 78.50% to 99.00% after the training, indicating a significant improvement in participants’ understanding and practical skills. All participants (100%) expressed high satisfaction with the content, methods, and overall benefits of the program. The resulting floor cleaning soap exhibited a distinctive aroma of patchouli and citronella, as well as good product stability, making it a promising environmentally friendly household product with market potential. Participants’ enthusiasm was demonstrated by their intention to further develop the product as a home-based business. This program is expected to enhance community skills, promote economic independence, and encourage the sustainable utilization of local resources.

Abstract

An increase in waste in urban areas, especially in landfills, can produce leachate that has the potential to pollute the environment. The Blang Bintang waste treatment facility, which uses a sanitary landfill system, is in a hilly area with complex geology dominated by andesite volcanic rocks. This study aims to identify and estimate the level of leachate contamination at the Blang Bintang landfill in Aceh using Electrical Resistivity Tomography (ERT).  Four ERT profiles were measured in the leachate treatment facility area, spanning 180 meters in length and up to 30 meters in depth. ERT data analysis using the Res2dinv software produced an accurate model with an RMS error of 10%-20%. The modeling results indicate the presence of conductive zones (5–150 Ohm.m) near the surface layers of profiles 1 and 2, suggesting leachate contamination. The electrical resistivity tomography (ERT) model further demonstrates leachate accumulation in the subsurface, which poses a potential risk to groundwater quality. In Profile 3, conductive zones (5–200 Ohm.m) are observed along the underground leachate pipeline. For Profile 4, conductive layers (15–250 Ohm.m) are attributed to seepage from the first leachate pond, indicating substantial contamination. This study provides landfill managers with valuable data on subsurface contamination that cannot be identified from surface observations. It also advances geophysical methods for environmental impact assessments.
