Abstract

Addressing the problem of increasingly complex urban household waste requires a multi-aspect approach. This study, therefore, aimed to develop a strategy to manage household wastes in the city of Banda Aceh based on five aspects including policy, institutional, funding, community participation, and operational technique aspects. It was conducted using in-depth interviews with garbage experts and a review of national and municipal policy documents. The qualitative data obtained was processed using Nvivo software. The investigation revealed that legal foundation of municipal waste management derived from the national and city level whereas there is no legal basis at provincial and village levels. In the perspective of institutional aspect, lack of management personnel, budget allocation, and coordination among the key stakeholder have contributed to weak institutions. As regards technical operation aspect, it can be further improved by proper sorting of waste, use of temporary disposal sites, swift waste transportation, time management of waste transportation and non-single use material campaign. Therefore, these aspects need to be developed sustainably to achieve the target of 30% waste reduction by 2025.

Abstract

This study aims to evaluate the effectiveness of water treatment process units including intake, aeration, pre-chlorination, coagulation, and flocculation at the Krian 2 Water Treatment Plant (IPA). Each unit has an important role in ensuring the quality of raw water into clean water that meets standards. The evaluation was carried out using a quantitative descriptive approach, using primary and secondary data obtained from field observations and laboratory tests. The results showed that the intake unit functioned quite well in supplying raw water with a stable discharge. The aeration unit was able to increase dissolved oxygen levels and reduce iron (Fe) and manganese (Mn) levels. The disinfection process showed effectiveness in reducing the number of pathogenic microorganisms, although it was influenced by the dose and contact time. The coagulation and flocculation units worked effectively in reducing turbidity and suspended solids through the addition of coagulant chemicals, namely PAC. Overall, the processing units at IPA 2 Krian have shown quite good effectiveness in producing clean water, although there are several technical aspects that need to be optimized to increase process efficiency.

Abstract

The shipyard of PT. X generates a huge amount of hazardous trash from ship repair activities, such as sandblasting waste, spent oil, used paint cans, and cleaning cloths. The purpose of this study is to classify and appraise B3 waste management operations, as well as to evaluate their execution. Data were gathered from observations, measurements, and interviews with the person in charge of Hazardous Waste Storage at the shipyard of PT. X. This study uses four stages in its implementation method, namely data collection, data processing and analysis, withdrawal, and provision of recommendations. Then the data will be compared with the applicable regulations. The average percentage of scoring was 73.375% with the achievement of "GOOD". However, the aspect of B3 waste storage needs to be improved because it got a low score of 56% with the achievement category of "FAIR". The same thing also happened in the aspect of packaging and container of B3 waste which only got a score of 37.5% with the achievement category of "POOR". With low scores for these aspects, it will result in the risk of environmental pollution, endanger the health and safety of workers, and can damage the company's reputation because it has violated existing regulations. Therefore, it is necessary to make improvements to improve the suitability of Hazardous waste management at PT. X based on applicable regulations.

Abstract

Biogas is a potential renewable energy source, but the content of impurity gases such as carbon dioxide (CO2) and hydrogen sulfide (H2S) reduces its quality and efficiency as a fuel. This study aims to analyze the effectiveness of the adsorption method using a combination of coconut shell activated carbon and natural zeolite in increasing methane (CH4) levels in biogas. The biogas used was produced from a cattle farm in Carangwulung Village. The variables tested included variations in the composition of activated carbon (C) and zeolite (Z) adsorbents with biogas flow rates (0.2; 0.4; and 0.6 L/min). The test was carried out with an adsorbent mass of 300 grams activated by KOH and the resulting pressure ranged from 9–13 mbar. The results showed that the adsorbent composition of 50C:50Z with a flow rate of 0.2 L/min gave the best performance. Under these conditions, CH4 levels could increase from 45% to 87%, where there was an increase in methane by 48%. The adsorption process at low flow rates provides optimal contact time between gas and adsorbent, thus increasing the efficiency of increasing CH4 levels. Thus, the combination of coconut shell activated carbon and natural zeolite at low flow rates is effective in improving biogas quality through the adsorption process.

Abstract

Accurate and comprehensive documentation is required for the long-term conservation of heritage buildings. This study aims to integrate the interior and exterior data of the Al-Syuro Cipari Mosque using 3D modelling and a combination of terrestrial laser scanning (TLS) and handheld laser scanning (HLS). Two integration methods were compared — free-net and independent georeferencing — to determine the most effective approach. Data was acquired using a Leica RTC360 TLS for exterior areas and a Leica BLK2GO HLS for hard-to-reach interior areas, particularly the ablution area and the mosque tower. The results showed that both methods successfully integrated the interior and exterior data without any gaps in the transition zones where the architectural elements were clearly defined. Free-net georeferencing produced models with an RMSE of 0.003 m and 66% overlap, whereas independent georeferencing offered greater processing flexibility, albeit with the need for special attention to be paid to systematic errors. Statistical tests revealed no significant discrepancies between the actual dimensions of the objects and the point cloud models in either method. The resulting integrated 3D model can be used to document, maintain and conserve heritage buildings with adequate geometric accuracy.

Abstract

One of the pollutants that must be controlled in rivers is the level of nitrite. Excessive amounts of nitrite are detrimental because they affect the quality and health of aquatic ecosystems. This study aimed to determine the effectiveness of eco enzymes in reducing nitrite levels in polluted river water as an alternative to conventional water treatment technologies. Three types of eco-enzyme made from vegetable, tomato and orange waste were used in this study. The experiment also aimed to evaluate the potential of reducing nitrite levels and its effect on pH performance. The results showed that adding 5% Vegetables Eco Enzyme (VEE), Tomatoes Eco Enzyme (TEE) or Oranges Eco Enzyme (OEE) to river water samples with an initial nitrite level of 4.813 mg/L produced the best results, with VEE showing the greatest effectiveness. This is because the nitrite concentration was reduced by 100% in the 4^(th) hour for VEE, the 6^(th) hour for TEE and the 8^(th) hour for OEE. For the pH parameter, there was a significant decrease, but it remained within the quality standard of pH 6–9. Statistical analysis using t-tests and ANOVA showed significant differences in both nitrite levels and pH results, as well as in the type of treatment.

Abstract

PT XYZ is a shipping company that operates in the ad hoc and short-term contract (spot charter) market. The company faces challenges in selecting the most profitable cargo offers and in managing fuel consumption in order to maximise profits and minimise operational costs. This study aims to develop a mathematical model that optimises revenue through optimal cargo selection, while simultaneously minimising operational costs, including fuel consumption for the main and auxiliary engines. The model is based on the actual conditions of the company's fleet and focuses on tramp general cargo services operating under less-than-shipload (LTS) conditions. In addition to addressing fuel management, the study covers fleet routing, vessel allocation and port docking considerations. The proposed model uses a mixed integer nonlinear programming (MINLP) approach to optimise variables such as sailing speed, ship displacement and the sequence of port visits. Feasibility analysis using real fleet data and hypothetical cargo offers indicates that the model consistently produces viable solutions. Sensitivity analysis of key parameters within a variation range of -50% to +50% from their nominal values confirms that the model's outputs remain within acceptable bounds.

Abstract

Sambai oen peugaga is a traditional Acehnese dish closely associated with the month of Ramadan and contains more than 40 types of local medicinal plants. This dish serves not only as a complementary culinary delight but also holds significant ethnopharmacological value. This study aims to analyze the role of sambai oen peugaga in supporting health during fasting as well as to explore the underlying local wisdom values. The method employed is a qualitative descriptive approach through a literature review of various scientific and cultural sources. The findings indicate that most plants used in sambai oen peugaga contain active compounds such as flavonoids, saponins, curcuminoids, and essential oils, which exhibit anti-inflammatory, antioxidant, immunostimulant, and antimicrobial effects. The combination of these compounds supports digestive health, immune function, and reduces oxidative stress during fasting. From a socio-cultural perspective, sambai oen peugaga functions as a medium for transmitting values, strengthening family cohesion, and reflecting a harmonious relationship between humans and nature. These findings underscore the importance of preserving traditional plant-based culinary heritage as part of community health systems and open opportunities for developing locally competitive functional food products.
