Abstract

Electric vehicle (EV) is an alternative expected to be tail-pipe emission-free and improve public health. Switching conventional or internal combustion engine vehicles (ICEVs) to EVs becomes a potential strategy for realizing urban sustainability. The study aims to review the environmental impact between ICEV and EV in Lithuania, China, Canada, Poland, Czech Republic, Italy, United States, and Australia. Then, the review result is compared to the Indonesia context as lessons learned. A comparative study with a qualitative descriptive method was carried out. The main activities are a literature review. The works of literature were collected, classified, and reviewed to find out significant findings on the environmental impact of ICEV and EV. Assessing the vehicle in all life-cycle (LC) phases is an essential issue. The entire LC of products may significantly impact the environment due to the utilization of raw materials through a process that causes adverse environmental impacts. Therefore, Life-cycle assessment (LCA) is proposed to estimate the environmental effects related to all the LC stages of EVs. Thus, LCA could be a critical tool. Numerous cases in several countries show that EVs were not always more environmentally friendly than ICEVs. The review indicates that EVs and electricity-generating mix scenarios play a significant role in performing LCA due to the performance of an EV is extremely dependent on the energy consumed through its operation phase. Additionally, the results show how significant renewable energy sources (RES) are in the electricity-generating mix that provides different environmental impacts. In the Indonesia context, the environmental impact of EV is predicted to be higher than ICEV due to the electricity generating mix is still lower than 20% in 2023. Optimizing the electricity generating mix scenario by increasing the RES, implementing clean technology power plants, and applying vehicle recycling are excellent strategies to promote sustainable development in the EV industry. However, economic and social aspects shall be considered to get comprehensive results in further research.

Abstract

The power factor grades are an indicator to determine the effectiveness of the electric power either distributed or used by consumers. A high power factor indicates that the electrical loads are using energy efficiently. Due to the increase in inductive load, there will be a decrease in the power factor, which in turn affects the distribution of electrical energy. In this research, an investigation has been carried out to observe the background that influences the low power factor at public hospital (RSUD) of Manokwari and recommend the need for a basis for improving the power factor at the hospital. Primary data on lighting and electrical equipment, along with their respective electric power capacities and power factors, are collected and measured onsite. Then the data is analysed based on the theoretical basis of power factor improvement. Based on the investigation, there are two focus points in the hospital to be observed, i.e., motor pumps and total load at the main panel. The calculation results show that pump motors 2 and 3 need to be compensated by increasing the power factor to 0.9 so that reactive power is reduced to 1.42 kVAR and 1.24 kVAR, respectively. In the same way, apparent power can also be upgraded to 0.85 kVA and 1.46 kVA by installing bank capacitors of 30.35 mF and 26.63 mF, respectively. On the other hand, the largest load connected to the main panel needs to be corrected to reduce the reactive power and apparent power to 17.86 kVAR and 9.5 kVA through the installation of a capacitor bank of 387.75 mF. This correction will increase energy efficiency while gaining economic benefits on both electricity bills and waiving penalties.

Abstract

As the needs of human life increase, the need for electrical energy will also increase. Currently, fossil energy, which is widely used as fuel for the provision of electrical energy, is running low. In Indonesia, renewable energy sources have not been utilized properly, such as wave energy. This study discussed how to design a prototype of a sea wave power plant. The problem is, how to be able to utilize the energy of sea waves to the maximum. The purpose of this research is to find solutions and designs to utilize recoil starter as a prototype of ocean wave power plants. The methodology used in this study is an experiment in which the prototype made is given a certain treatment and then measurements are made. His data analysis technique is descriptive analysis. Based on the results of measurements and observations, the performance of the tool is not only influenced by the height of the wave, but also the period of arrival of the sea wave and the ballast load of the tool. After measurements were made on the first day of Maruni beach, the prototype could produce an average power of 4.21 watts for an average wave height of 0.35 cm and Maruni beach on the second day could produce an average power of 5.68 watts for an average wave height of 0.4 m. While on the first day Amban beach obtained an average power of 3.29 watts for an average wave height of 0.37 cm and Amban beach on the second day could produce an average power of 14.26 watts for an average wave height of 0.5 m.

Abstract

This study aims to reveal the various renewable energy sources that have the potential to be developed on the island of Java, Indonesia. Because it is cheap and easy to reach, non-renewable energy is widely used as a source of energy for people's lives. The negative side of non-renewable energy sources forces local governments to look for alternative energy sources that are more environmentally friendly. Environmentally friendly alternative energy is rarely studied, specifically on the island of Java, through literature studies. Therefore, this study used a research method: a literature study on 28 Scopus, WoS, and Sinta-indexed articles. This literature study yields the information that 10 types of renewable energy sources have the potential to be developed in Java. These renewable energy sources can be further developed using technology according to their potential in each province. Thus, this research has succeeded in linking various renewable energy sources that have the potential to be developed on the island of Java.

Abstract

Waste that has a high organic matter content can be treated biologically under anaerobic conditions or using bacteria that can live in an environment without oxygen. One method of wastewater treatment that can reduce high organic content is the Fixed Bed type anaerobic reactor system. The purpose of this research is to compare the treatment of organic wastewater using a Fixed Bed type anaerobic reactor that has been implemented in Germany with that implemented in Indonesia. The method used is a literature study by comparing case studies between the two countries, so the methodology used is a systematic literature review. Based on the results of the discussion, it is known that the organic waste that is processed using an anaerobic reactor carried out in Germany has several differences starting from the sub-stages of the process, and operations to the materials used such as the use of pumps, installation storage tanks, sewage filtration, use of stainless steel and heat exchangers. These differences if applied in Indonesia can cost relatively a lot so they are not suitable for application in Indonesia. Based on the literature study, it was concluded that the anaerobic wastewater treatment solution using a fixed bed type in Indonesia can be a good opportunity and can be imitated by other countries because it has simple equipment, but the reactor efficiency and the resulting percentage of methane production are relatively high. although the required HRT is long, anaerobic catalysts can be used as a solution.

Abstract

The use of new, renewable Energy has been initiated since the promulgation of Law Number 30 of 2007 concerning Energy. Now, the urgency is starting to appear with the enactment of Presidential Regulation Number 112 of 2022 concerning the Acceleration of Renewable Energy Development for the Supply of Electric Power. Solar thermal Energy is very abundant in areas with tropical climates, such as Indonesia, which is always illuminated by the sun all year round. This is an energy source that has great potential to be developed. PT One of the locations for implementing PLTS by PT X is in the Cilacap Regency. PLTS, with a capacity of 1,340 kiloWatts with electricity production of 833 MWh and an investment value of IDR 10 billion per 1 MW, operational since August 2021, is used to support the provision of electrical energy sources for office activities and employee housing, with an average reduction in equivalent CO2 emission intensity of 7.60 %. Implementation of the use of PLTS still faces various challenges, especially for commercial use, such as a complicated licensing process that is not yet aligned between authorized agencies, the limited availability of PLTS infrastructure and technology and supporting facilities such as electricity transmission networks in Indonesia, thus affecting the investment value or installation costs, limitations human resources during the Covid-19 pandemic, to allegations that political factors and conflicts of interest between electricity supply sectors cause the minimal use of PLTS. On the other hand, considering that significant climate change is starting to be seen and felt, the existence of PLTS is expected to accelerate the achievement of reducing greenhouse gas emissions. This paper will provide an overview of the implementation of PLTS use for the commercial sector, which has been carried out as evaluation material for all parties to prepare environmentally sound sustainable development strategies through the implementation of PLTS use.

Abstract

Bottom ash incinerator produced by PT. X from various waste from production tenant activities has physical characteristics like cement, so it possible to use it as a substitute for cement in paving block mixtures. This utilization aims to determine the effect of using bottom ash on paving blocks according to the compressive strength and water absorption parameter. The composition of cement, and bottom ash in making paving block was varied in this experiment, for amount of sand and water used were same. Drying process for the paving block took 28 days. The bottom ash replace cement by 0 percent, 5 percent, 10 percent and 15 percent respectively, and two replications done for measurement. The quality of paving block was test based on the SNI 03-0619-1996 to determine the level of quality of paving block. The results of this study indicate that the treatment used were significance different based on compressive strength but were not significance different based on water absorption parameter. The substitution of bottom ash in paving blocks based on compressive strength, for treatment C (with 10 percent bottom ash) complied with quality B and treatment D (with 15 percent bottom ash) complied with quality D of paving block standard. Based on water absorption parameter all treatment complied with quality B and D (treatment A, B, and D complied with quality D and treatment C complied with B quality). By considering booth parameter, treatment C (with 10 percent bottom ash) complied with B quality and treatment D (with 15 percent bottom ash) complied with D quality. Other finding from these research showed at least 10 percent bottom ash from incinerator replaced cement used in making paving block.

Abstract

Economic growth and increasing population density have an influence on the large need for electrical energy in Indonesia. The amount of energy needed is directly proportional to economic growth and population density. This condition could threaten energy security in Indonesia if all stakeholders still depend on non-renewable energy. Coal, oil, and natural gas, which are continuously exploited for generating electricity, will eventually run out and will no longer be able to meet Indonesia's electrical energy needs. Apart from that, the use of non-renewable energy also has a negative impact on the environment. Indonesia is a country that is rich in renewable energy sources that can be used as a source of energy for generating electricity, but there are still obstacles in processing and using them, so they are not optimal. This paper aims to analyze the potential and challenges of providing electrical energy in Indonesia. The method used is a descriptive method using primary and secondary data and literature studies. The results of this study show that the potential for renewable energy that can be processed and developed for electricity generation is quite large, namely from energy sources originating from geothermal, hydropower, mini-hydro and micro-hydro, bioenergy, solar power, wind energy, and ocean waves. The survey results show that 52% of the public agree with the use of renewable energy, and 43% agree with the use of nuclear energy as a source of renewable electrical energy. The reason for choosing nuclear energy is the reliability of the energy supply. A strategy for developing renewable electrical energy can be formulated based on the opportunities and challenges currently faced to achieve energy security in Indonesia. Efforts to develop renewable electrical energy need to be carried out with the cooperation of all relevant stakeholders so that the sustainability of electrical energy in Indonesia can be realized.

Abstract

The number of motorised vehicles, according to the Central Statistics Agency, reached 94,373,324 in 2012, and there was an increase in 2013 to 104,118,986. This is influenced by increasingly rapid population growth and the increasing need for transportation. Used lubricating oil is categorised as B3 waste, which can be seen from its characteristics and its constituent components. Rice husks resulting from milling that are not utilised optimally are usually only used as ash, or the use of rice husks has so far been limited to just being thrown away. Research was carried out regarding the activated carbon test from rice husk waste to adsorb Pb in used lubricating oil using a sulfuric acid activator and determine the effectiveness of reducing Pb (lead). The mass ratio of rice husks before and after calcination is 1:2, where the initial weight of the husks before calcination is 250 grammes to 125 grammes after undergoing calcination. A mass of 10 grammes of adsorbent that has been activated using sulfuric acid and a stirring time of 60 minutes can reduce the lead content of the used lubricant from 49,569 ppm to 39,241 ppm.
