Abstract

Vertical Clarifier Tank (VCT) has a very crucial role to separate oil, water and sludge by gravity, where oil with a smaller specific gravity of 0.8 grams / cm3 will be in the uppermost layer, while water whose specific gravity is 1 gram / cm3 will be in the middle layer, and sludge with a density of 1.3 grams / cm3 from the Vertical Clarifier Tank (VCT). The experimental design of this study was to determine the appropriate depth of the inlet pipe to obtain low levels of impurities during oil extraction. The results of the study obtained from variations in the depth of 25 cm, 40 cm, 55 cm, and 70 cm inlet pipes used as the inflow of crude oil from Crude Palm Oil with variations in sedimentation time of 100 minutes, 120 minutes, 140 minutes, 160 minutes, 180 minutes, and 200 minutes, obtained the least level of impurities in the Inlet Pipe which has a length of 55 cm with a variable sedimentation time of 200 minutes.

Abstract

Abstract Infrastructure development continues to increase, especially on highway pavement, requiring a lot of materials such as coarse aggregate, fine aggregate, filler and asphalt (Pen 60/70) as a binder. However, the depletion of petroleum reserves which has an impact on the availability of asphalt has encouraged innovation to reduce its use. One potential innovation is the use of a combination of plastic waste (LDPE), Crude Palm Oil (CPO), and used inner tubes as an alternative binding material. This research examines the optimization of the use of this combination in the Asphalt Concrete-Wearing Course (AC-WC) mixture. Indonesia, as a tropical country with a significant area of oil palm plantations, produces abundant CPO. In addition, high use of plastic produces plastic waste that is difficult to decompose, and Indonesia is one of the largest contributors of plastic waste in the world. By utilizing this waste in road pavement, this research seeks to reduce environmental impacts while providing alternative solutions for pavement materials. Tests were carried out with three variations, namely V1 = 3% LDPE : 2% CPO : 10% inner tube : 85% pen 60/70;  V2 = 4%LDPE : 2%CPO : 10% inner tube : 84% pen 60/70; V3 = 5%LDPE : 2%CPO : 10% inner tube : 83% pen 60/70 to determine the characteristics of stability, flow, VMA, Void in Mix (VIM), VFB, and Marshall Quotient (MQ). The test results show that the Optimum Asphalt Content (KAO) value is 5.5%. All variations meet the minimum stability specifications set by Bina Marga(2018). Keywords : LDPE, CPO, Karet Ban Dalam, Pen 60/70, AC-WC

Abstract

This community service activity aims to enhance health workers' understanding of digital literacy and community empowerment techniques by utilizing digital access, thereby supporting more effective public health literacy. The activity was conducted at two health centers in Simeulue Regency, namely Teupah Selatan Health Center and Teupah Barat Health Center, on June 17, 2024, from 09:00 to 13:00 WIB, with a total of 44 participants. The method used in this activity involved adapting the Lasswell communication process, where information was conveyed by resource persons and health promotion officers to health workers offline. The activity was considered successful due to the enthusiasm shown by the participants. The evaluation results indicate an improvement in the participants' knowledge and skills, as well as a positive impact on their understanding of digital literacy

Abstract

Coconut (Cocos nucifera) is a strategic commodity for agro-industrial development in Indonesia, especially in Sumatra, which is home to 34.5% of national coconut plantations. One of the major producers, with a coastal geography and tropical climate that is highly suitable for coconut plantations, Aceh Barat, is currently facing the threat of degradation of coconut plantation land loss due to the government's Regional Action Plan for Sustainable Palm Oil Plantations (RAD KSB Aceh 2023-2026). This study aims to look at the total coconut plantation land by integrating geospatial analysis (QGIS) and SARIMAX time series modelling to map coconut plantations in 2024, estimate production trends, and assess the viability of the agro-industry amidst land use conflicts. Results from mapping with QGIS software showed a drastic decrease in coconut area from 3,330.25 hectares in 2022 to 928.2 hectares in 2024. The reduction in coconut plantation area is signalled by RAD KSB's oil palm expansion target of 1,078,728 hectares by 2026. In addition, the results of the mapping obtained several sub-districts with the largest contribution in West Aceh, namely Kaway XVI (234.82 ha) and Muereubo (217.46 ha) of coconut plantation area, while Bubon (16.67 ha) and West Woyla (38.42 ha) experienced significant land conversion. The study also calculated coconut fruit production of 1,229,267 kg (1,229 tonnes) per month from 12 sub-districts, and generated revenue from selling only coconuts of IDR 2.23 billion. SARIMAX forecasts showed high accuracy (RMSE: 700-704; MAPE: 0.19-1.05%) for 10 sub-districts, except Bubon (MAPE: 2.13%) and West Woyla (MAPE: 1.05%) due to data volatility. Furthermore, projections for the next five periods were carried out and obtained results, namely, Period 1 (104,425.88 kg), Period 2 (94,851.07 kg), Period 3 (97,399.50 kg), Period 4 (96,721.21 kg), and Period 5 (96,901.75 kg) which were dominated by stable production in the core area of Kaway XVI: 311,870 kg/month, but volatile in smaller areas. Spatial analysis prioritises Samatiga (58.53 ha) and Arongan Lambalek (79.27 ha) for agro-industrial development, with potential for value-added products.
