Abstract

Bioethanol is one of the alternative materials that can reduce dependence on non-renewable fuel oil. The process of making bioethanol produces by-products in the form of waste. Yeast mud is solid waste from the initial precipitation process of ethanol production. Yeast mud contains organic carbon of 39.33%, total nitrogen as nitrogen compounds of 1.76%, and a C/N ratio of 22. The organic carbon content contained in yeast mud exceeds the 2018 SNI value of a maximum of 32%. This study aims to determine the time needed to produce solid organic fertilizer in accordance with the Indonesian National Standard. The parameters used to determine the quality of solid organic fertilizer produced are C-Organic content, Nitrogen content, and C/N ratio. The method used in this research is aerobic composting with variations in the mass of yeast mud waste (1 kg; 2kg; 3 kg; 4 kg; and 5 kg) and variations in composting time (3; 4; 5; 6; 7 days), as well as an aeration rate of 1.5 l/min. The results showed that the C-Organic content that met the maximum SNI standard of 32% was obtained under the condition of a mass of yeast mud waste of 1 kg with a time of 5 days with a C-Organic content of 31.45% and a mass of yeast mud waste of 2 kg with a time of 7 days with a C-Organic content of 31.96%.

Abstract

The increase in waste generation in Indonesia in 2023 has reached 17,027,843.29 tons/year. The largest source of waste is categorized as food waste composition originating from household activities with 3997.2 tons/year or a percentage of 38.4%. One approach that can overcome this problem is by using Black Soldier Fly larvae. These larvae can obtain energy and nutrients from vegetable scraps, food scraps, animal carcasses, domestic waste and liquid waste as their food source. This research aims to analyze the effectiveness of decomposing household waste using BSF larvae and the growth of BSF larvae. This research involves a variety of larval feed from household waste that has not been cooked or has undergone a cooking process as well as waste that contains fiber, carbohydrates and is high in protein. The results showed that BSF larvae with a combination of boiled water spinach, catfish head waste, and stale rice (H1) had the highest reduction value, reaching 90%. Meanwhile, the highest weight gain for BSF larvae was on the substrate of boiled water spinach, catfish head waste, stale rice, and vinegar solution (H2) with an ECD value of 69%

Abstract

Increasing Green House Gases (GHG), including Carbon Dioxide (CO₂), have the potential to increase global temperatures, thereby causing climate change. Total CO₂ from human activities, for example transportation, electricity generation, industry, trade and agriculture, is expressed as a carbon footprint. Andalas University (Unand) has facilities that produce GHGs. This research aims to analyze the carbon footprint in Unand in the transportation sector. Samples were taken at the main gate (point 1) and back gate (point 2) Unand. For these two locations, the number of vehicles and fuel is calculated using the direct calculation method. The carbon footprint calculation refers to the Intergovernmental Panel on Climate Change (IPCC). The next step is to identify the potential for GHG reduction in Unand. The alternative GHG reduction observed is the absorption of CO₂ by vegetation. The research results show that the total carbon footprint on the Limau Manis Unand Campus is 2,221,020 kgCO₂eq/year from Point 1 and Point 2. The total CO₂ eq absorption capacity by vegetation on the Limau Manis Unand Campus is 9,297,557.51 kgCO₂ equivalent/year. When compared with the total CO₂ eq from transportation activities, the potential for reducing CO2 eq by vegetation is quite large. So, the Unand Campus road vegetation is still sufficient to reduce the 'contribution' of CO₂ eq from transportation activities in Unand to greenhouse gases. However, it is necessary to consider other possible sources of CO₂ besides transportation and the need to maintain existing vegetation

Abstract

Gold is one of the largest mining products in Indonesia, amounting to 34,39 tons in 2022. In addition, gold is considered to be one of the safest investment instruments currently. The main raw material for gold production is dore bullion, namely metal bars containing gold and silver. Dore bullion production has various impacts on Life Cycle Assessment (LCA) studies. High levels of dore bullion production cause high use of fuel, energy, raw materials, and emissions, so it is necessary to analyze and identify the impact of the precious metal production process using the LCA method. The impacts produced in this research are midpoint and endpoint impacts based on the ReCiPe 2016 (H) method for the cradle-to-gate scope. This LCA study examined 14 midpoint and 3 endpoint impacts. The dominant midpoint impact results are mineral resource scarcity (149,581,850,000 kg Cu eq), water consumption (167.905,36 m3), and global warming (4.514.295,80 kg CO2 eq), while the endpoint impacts are resources (34.608.348.000 USD2013), human health (4,7626 DALY), and ecosystem quality (0,0150 species.yr). The largest impact contributors were the drilling process unit (mineral resource scarcity), milling process unit (water consumption), and dewatering process unit (global warming).

Abstract

Increased transportation activities in this city cause air pollutant emissions, one of which is Total Suspended Particulate (TSP), which has an impact on air quality. This study aims to measure TSP concentration and map its distribution. Data on TSP concentration, air temperature, wind speed, and air humidity were collected using instruments such as High Volume Air Sampler (HVAS), hygrometer, and anemometer. TSP concentrations were modeled with AERMOD based on the obtained data and associated meteorologicalconditions. The results showed that TSP concentrations varied significantly depending on traffic volume and weather, with the highest concentration of 184.8 μg/m3 at point 1 on the first day and the lowest of 9.7 μg/m3 at point 5 on the second day. The distribution of TSP tended to the Southeast, West, and North according to the AERMOD model. Questionnaire results in the sampling areas show that there are still people who are not aware of the impact of TSP pollutants. The conclusion of this study is the presence of TSP pollutants on Tandes Highway, which is influenced by meteorological factors and traffic volume

Abstract

This research evaluates the performance and combustion emissions of boilers using solid palm oil waste fuel. Experiments were conducted by measuring operational parameters such as temperature, pressure and thermal efficiency at different load variations. Analysis of the combustion of three types of oil palm biomass shows that oil palm shells consistently reach peak temperatures faster and higher (800-900°C) than empty palm fruit bunches and palm fronds (600-700°C). This combustion pattern indicates that palm kernel shells are more suitable for rapid energy release applications. In contrast, empty palm fruit bunches and palm fronds are ideal for steady and sustained combustion. In addition, the emissions analysis identifies exhaust gas components including CO, CO₂, SO₂ and NOₓ. The results show that palm oil solid fuel has the potential to be an efficient alternative fuel with thermal efficiencies of up to 80%. However, there is still a need to consider exhaust emissions due to increased CO and NOₓ compared to conventional fossil fuels. This study provides insight into the use of palm oil waste for renewable energy, although further optimisation is required to reduce the environmental impact.

Abstract

The number of traditional houses in Aceh called "Rumoh Aceh" is decreasing due to the changing needs and lifestyle of the Acehnese people, who prefer to build and live-in modern houses. Several Rumoh Aceh can still be found in rural areas in varying conditions but their numbers are decreasing. The well maintained Rumoh Aceh which are still inhabit by the owners are Rumoh Aceh in Lubok Sukon village, Aceh Besar. This phenomenon is the background for conducting this research, which aims to reveal the strategies carried out by community to preserve Rumoh Aceh. Qualitative research with in-depth interviews and observations was carried out to gather information from the owners and residents. Using purposive sampling method, 7 Rumoh Aceh which were 80 years old and over 100 years old, were selected for the case study. The results reveal that adaptation and revitalization strategies are the main strategies to preserve Rumoh Aceh. Adaptation is carried out by adding facilities and modifying the interior and exterior to accommodate modern needs and comfort. Revitalization is held by carrying out festives, cultural and religious activities. Rumoh is used as a museum and home stay and various tourist attraction events are also held to provide experience moments for visitors. The activities are known as experience tourism strategies.

Abstract

Brackish water has a characteristic cloudy yellow colour and a higher pH than fresh water. Not a few residents complain about the condition of the water, which feels brackish to salty, their skin feels sticky after bathing, this is due to the salinity in the water (Ismawan, Sanjoto, & Setyaningsih, 2016). The salinity in brackish water is 0.5-30 ppt, TDS is 1500-6000 ppm. The filtration process uses zeolite and pumice as adsorption media. The sample water is passed through the filtration media from bottom to top and collected in useful as adsorbent because of zeolit and pumice have pores that can bind molecules in water. From the research results, the average value of zeolite media was able to remove salinity of 28.84%, TDS 28.06%, conductivity 28.14% and TSS 92.20%. And pumice stone media is able to remove salinity of 28.57%, TDS 27.81%, conductivity 27.88% and TSS 91.20%. The adsorption capacity value was calculated using the Thomas method and the result obtained for the zeolitic media was 0.059 mg adsorbate/mg adsorbent, while for the pumice stone media it was 0.026 mg adsorbate/mg adsorbent. It can therefore be said that the zeolite media has a greater capacity and removal capacity than pumice.

Abstract

Since the Covid-19 pandemic, the online sales business has grown rapidly, especially through e-commerce applications. E-commerce has become popular because it offers a variety of products at different prices and is often cheaper than direct sales. Prices in e-commerce are affected not only by the price of the goods, but also by service charges, shipping costs and other fees. Well-managed shipping costs are important so that buyers, sellers and applications all benefit. The number of shipping services available in e-commerce requires analysis to determine the best shipping service. This research aims to compare the best shipping services as a reference for sellers and buyers. This research examines how the e-commerce system selects automated shipping services and analyses whether the selection is optimal based on the category of goods, size, shape and distance. The selection of delivery services is modelled with a neural network to describe different possibilities based on the given criteria. The results show that the optimal use of delivery services is determined by handling according to category, size, shape, distance and special conditions. E-commerce should further improve the benefits of delivery services through better website connectivity and digital services.
