Abstract

Dependence on the provision of electricity using fossil fuels is a major energy supply problem in Indonesia. Therefore, it is necessary to provide new and renewable alternative fuels that are effective, efficient, and environmentally friendly. One of the alternative fuels is bagasse biomass. The purpose of this study was to determine the amount of bagasse produced by sellers of sugarcane juice drink in Pontianak City, in order to determine the estimated value of bagasse. The research method used was direct data collection and laboratory testing . Based on the results of the study, the number of vendors of sugarcane juice beverages producing bagasse was 169. Of this amount, produce bagasse that can reach 1,030.9 kg/day. Based on the test results, the estimated moisture content of bagasse was 3.28%, ash content was 0.77%, and carbon remained at 7.65%. So, if converted with the test results of the calorific value of bagasse and made into briquettes bagasse (bio briquettes), which is 19,648 kJ/kg with a density of 0.416 kg/m3, then converted into a potential calorific value of 242,849,280 J/year.

Abstract

Transportation is a sector that contributes significantly to CO2 gas emissions and has the potential to continue to increase along with the addition of fossil fuel vehicles. Indonesia has plans to switch to electric vehicles as an alternative to reduce greenhouse gas (GHG) emissions from the transportation sector. The battery is an important component of an electric vehicle, and there are several alternative technologies that can be used. This paper  simulates the selection of a suitable battery from various type of batteries, including Lead-acid (PbA), Nickel Metal Hydride (NiMH) and Lithium-ion (Li-ion). The selection is made using the weighted objective method by presenting 5 criteria: energy density; emissions generated for battery production; energy factor of the manufacturing process; availability of critical raw materials required for cathodes and anodes; and availability of recycling facilities. Supporting data to determine the magnitude of each criterion is obtained from literature reviews. The analysis and comparison was carried out by giving weight to the assessment based on the data obtained. The results of calculations carried out in the paper show that the Lead-acid battery is a viable option for use at current time.However, if Indonesia already has NiMH and Li-ion battery recycling facilities, or is capable of producing Lithium-ion batteries, then the criteria and calculation factors can be added and improved.

Abstract

Cibaligo River is the polluted rivers in Cimahi City. The river that flows through three districts and 6 sub-districts in Cimahi City catchment  area of 666.19 hectares of watershed with a total length of 7 km. The land use of the district through which this river passes is domestic, trade, agriculture, livestock and industry whose waste will end into the Cibaligo River. The impact of these activities causes the river to be polluted and a decrease in water quality. The purpose of this study was to determine the status of water quality from upstream to downstream which represents the transition, dry, and rainy seasons. Knowledge of water quality status can be used as basic data for controlling water pollution in rivers. The pollutant index (IP) method used in this study is in accordance with the Decree of the State Minister for the Environment Number 115 of 2003 concerning guidelines for determining water quality status. The results showed that the water quality status of the Cibaligo River from upstream to downstream represented that each season was categorized as heavily polluted with the highest index value being in the rainy season at the downstream point. The main contributor that causes river water to be heavily polluted is domestic wastewater, especially the presence of total coliform and fecal coliform that exceed the established quality standards. Based on the results of the research, efforts to tackle domestic waste are needed to improve the quality of this river water.

Abstract

Banda Aceh City is one of the dengue-endemic area. During a  10 year  period (2010 - 2019), the total number of cases of Dengue Hemorrhagic Fever (DHF) in Banda Aceh City  was 3,168 cases with a total of 16 deaths. Thus, it is necessary to map the vulnerability of dengue in Banda Aceh City. The purpose of this study was to map the distribution of dengue-prone areas in the city of Banda Aceh. The parameters used in the study were rainfall, air temperature, humidity, and population density. This parameter is used because it is considered to have a close relationship  to habitat for the development of the Aedes aegypti mosquito. Secondary data were collected  from the Central Statistics Agency (BPS), the Meteorology, Climatology and Geophysics Agency (BMKG), the Regional Development Planning Agency (Bappeda), the Marine and Fisheries Agricultural Food Service (DPPKP), and the Banda Aceh City Health Office from 2010 - 2019 shows that dengue cases correlate with rainfall of 25.07%. DHF cases correlate  to humidity, which is 42.06%. Meanwhile, the correlation between temperature and DHF cases was -47.26%. The results of the spatial analysis of DHF vulnerability show that  dengue is highly vulnerable   in Jaya Baru District, Baiturrahman District, Kuta Alam District, and Syiah Kuala District

Abstract

Many things must be considered in a production system in the industrial world, such as the performance of a machine or tool used. Productivity is closely related to smooth production. The low productivity of the machine will cause losses for the company, where this loss is caused by the use of ineffective and inefficientmachines. This study aims to determine the performance of the machine and the factors that cause damage to the press machine at PT Ciptaunggul Karya Abadi. The research was conducted using the application of TPM (Total Productive Maintenance) to increase productivity and maximize facilities. TPM is also accompanied by the OEE (Overall Equipment Effectiveness) method to measure the performance and accuracy of the machine used. This data is in the form of quantitative which is calculated using the methods mentioned above. The results showed that the average value of the availability rate was 95%, the performance rate was 87% and the quality rate was 99%. From these results, it can be seen that only the performance rate does not meet world-class standards. This is also obtained from the calculation of the six big losses, the largest percentage is in idle and minor stoppage losses, which is 47%. Alternative repair solutions can be carried out by implementing machine maintenance and continuous improvement,providing special training for operators, and reducing non-productive time.
