Abstract

Biodiesel production from kapok seed oil using calcined CaCO3 has been done. The objective of this study is to investigate the impact of varying concentrations of calcined CaCO3 catalysts on the biodiesel manufacturing process. The production of biodiesel involves two distinct processes, namely esterification and transesterification. The variation concentrations of the CaCO3 catalyst used in the experiment were 1%, 2%, 3%, 4%, and 5% (w/w). The results showed that the biodiesel nearly satisfied the ASTM D-1298 standard. The biodiesel generated using a CaCO3 catalyst with a concentration of 1% (w/w) and a contact period of 120 minutes exhibited the highest quality, with a biodiesel conversion rate of 41.57%.

Abstract

Utilization of new, renewable energy (EBT) resources is the most important field in developing countries like Indonesia. The development of effective methods for evaluating alternative energy sources in the automotive industry has always been a need for cost-effective design analysis and one of the viable energy sources is electrical energy. Electric Vehicles (EV) are the application of photovoltaic energy using a combination of a charge controller based on a battery charging strategy with a unidirectional PWM technique based on a grid to vehicle strategy in the Smart Grid. Energy supplies in the world are currently decreasing, especially the energy used to generate electricity. With the widespread use of electric vehicles (EVs), it is important to plan charging by considering the behavior of EV drivers and demand on the electricity grid. Because the average solar insolation value in Indonesia is quite high, this can minimize dependence on the electricity grid and maximize the use of solar energy for energy storage systems for electric vehicles.

Abstract

Breast cancer is a prevalent type of cancer affecting women worldwide. Additionally, Globocan reported nearly 400,000 new cancer cases in Indonesia in 2020, with 16% being breast cancer. The Ministry of Health has prioritised breast cancer treatment due to the high number of cases. Early detection is a crucial factor in increasing patient life expectancy. Stage 1 breast cancer, for instance, has a 5-year life expectancy of 100%. Breast ultrasound or mammary ultrasound is a commonly used method to detect various breast problems, including cysts and tumors. It is a relatively easy procedure, and the necessary equipment is generally available at Health Facility 1. Texture features are extracted from breast ultrasound images using Gabor and Gray Level Co-occurrence Matrix (GLCM) techniques. The resulting feature vector is then selected and its dimensions reduced to simplify the computing process. This vector is then used to train an SVM classifier to distinguish between benign and malignant cases. The accuracy of the classifier is 0.67 (training) and 0.66 (validation). Meanwhile, the loss obtained during training was 0.77 and during validation was 0.84. Further improvement is required for the accuracy of the model to be applicable.

Abstract

The population is growing at a slightly faster rate every year. The significant demand for electricity, supplied by electricity companies such as PT PLN (Persero), is also in line with this population growth. To ensure that the needs of the population are met, the reliability of the electricity distribution system is a priority. Performance indicators such as the System Average Interruption Duration Index (SAIDI) and the System Average Interruption Frequency Index (SAIFI) are available for PT PLN (Persero). The lower the SAIDI, the higher the efficiency and reliability of the distribution system. The comparative study of SAIDI and SAIFI on the 20 kV ULP Meulaboh City feeder is included in this study. According to the SAIDI-SAIFI reliability index of this study, SAIDI = 0.97177 hours/customer/year and SAIFI = 3.01215 outages/customer/year were achieved. Based on the SPLN 59:1985 standard for the 20 kV ULP Meulaboh City feeder in 2023 for January to June, this technology is considered reliable.

Abstract

The Katingan Hilir District of Katingan Regency, Central Kalimantan Province, is one of the areas experiencing the consequences of flood disasters. This research aims to analyse the flood-affected areas using the GIS method, integrating the Analytic Hierarchy Process (AHP) method in order to analyse the impact and influencing factors on flood events. This is one of the decision support system methods of Multiple Attribute Decision Making (MADM), which is included in the technical category. MCDM (Multi-criteria decision making) was developed by Thomas L. Saaty with the objective of identifying the most optimal and feasible problem-solving/alternative results through systematic evaluation procedures [1]. The parameters obtained based on the ranking of their influence on flood vulnerability are as follows: The following parameters were identified as influencing flood vulnerability: rainfall, distance from the river, slope, elevation, soil type and land cover. The results of the map overlay indicated that a total area of 403.11 km2 (67.1%) exhibited a low level of flood vulnerability, 146.93 km2 (24.5%) exhibited a medium level of flood vulnerability, and 50.34 km2 (8.4%) exhibited a high level of flood vulnerability. The area and percentage values indicate that the study location is a dominant area with a low level of flood vulnerability,yet it has a high category of flood-prone percentage approaching 10% of the total administrative area of the sub-district.

Abstract

The paddy fields are generally large expanses of land that are free of wind barriers, away from human settlements and power sources. Sparrows are one of the most common pests, which usually attack paddyfield in clusters. The researchers who use electronic equipment as controllers to produce output, sounds and electronic drives, use a power source from batteries. The wind turbine is one method of repelling sparrows and producing electricity, as the driving force for the sound-producing mechanical equipment, and the Nema17 motor as the generator for charging the battery. Paddy is grown seasonally so the wind turbine can be disassembled for use and for storage. Measurement of wind speed to determine blade length, with the help of Win & Wet website, blade design, power relationship characteristics with windspeed and turbine rotation were created.

Abstract

The large amount of liquid waste generated from urban activities can provide negative impacts, such as disease spread, environmental damage, and others. Therefore, treatment efforts before disposal into the environmental are crucial. One method of treating liquid waste that can be used is the trickling filter. The trickling filter method used in this research utilizes natural fibers, namely coconut fiber, as the packing media, replacing sand or plastic as the packing media in conventional trickling filters. Treatment of municipal liquid waste (domestic waste) using coconut fiber trickling filters is one application of biofilm technology in wastewater treatment, where a biological layer (biofilm) like mucus will grow on the surface of the media. This biological layer will meet the wastewater and degrade the pollutant compounds presentin the wastewater, resulting in water with lower biological oxygen demand (BOD) values than before. Theresult if water that is safe for disposal into the environment. This trickling filter reactor can degrade pollutants with degradation efficiency of BOD 91.3%, nitrate 50.25%, and ammonia 37.5% at the optimal flow rate of this study (0.256 L/min).

Abstract

Garbage is the remnants of the use of human activities that are no longer needed. Garbage is one of the things that can have a negative impact on development. Improvement through the participation of the community is the key to the success of efforts to build a city in order to create a clean and safe city from the adverse effects caused by waste. In 2019 the West Aceh District Environmental Service (DLHK) has carried out at least 129 m3 of garbage dumping and is only able to handle 114.3 m3 of waste from the total services spread across four sub-districts which are waste management services, namely Johan Pahlawan District of 66,601 m3, Samatiga 15,787 m3, Meureubo 31,486 m3, and Kaway XVI 22,524 m3. So waste becomes one of the serious problems for sustainable city development and a countermeasures must be taken. This research method uses the Likert scale method, the results of the calculation of the number of samples using the Slovin formula are 41 respondents. From the results of calculations based on the questionnaire submitted to the respondents, the score was 40.878%. So the conclusion is that the ADB1 housing complex community is still not satisfied with waste management, and it is also urgently needed support from various parties, both government and institutions related to waste management.
