Authors: Do NY , Le TA , Ngo XC 
Published: December 2022

Abstract
Energy efficiency and sustainability are important goals for countries all over the world. With the advancement of material technology, many new generations of high-efficiency motors are being researched and developed to replace induction motors (IM) to save energy. Line-start permanent-magnet synchronous motors (LSPMSM) are high-performance and ultra-high-performance motors that are emerging as an alternative to squirrel-rotor induction motors. Constructing the permanent magnets in the rotor is critically important in ensuring LSPMSM performance. The study uses the finite element method to analyze the characteristics of the motor. The study presented the influence of the permanent magnet structure in the rotor of the LSPMSM with a power of 22 kW and a speed of 3000 rpm on the electromagnetic field distribution in the motor, as well as the motor’s working characteristics to optimize the permanent magnet structure to optimize the performance of the LSPMSM. The analysis results show that the proposed LSPMSM has a 92.6% higher efficiency than the same-type induction motor. This is a suitable replacement for high-power and high-speed IM, which contributes to energy efficiency, so using fewer fossil fuels to reduce environmental impact is a sustainable development solution.

Published: December 2022

Abstract
Water treatment of river water is generally carried out conventionally, a rapid sand filter consisting of a coagulation unit, flocculation, sedimentation, and sand filtration. One of the disadvantages of sand filters is that it requires a large volume of water for washing, inconsistent quality, and escape of microorganisms less than 0.01 mm in size. Membrane technology can solve this problem with the advantages of including a more compact unit with a larger surface area per volume. The immersed membrane has another advantage that it is possible to integrate with sedimentation units so that it can save the land. This paper will study a comparison of the performance of the microfiltration membrane with sand filters in two drinking water treatment plants. The comparison method is based on technical specification, capacity, and quality performance. The results show that the quality of the microfiltration membrane filtrate is better than the sand filter. Overall immersed membrane microfiltration with pore size 0.05 µm had removal efficiency of E. Coli was 100%, turbidity 93 %, TSS 100%. Organic permanganate value 37%, and Microplastics 81.5%, whereas pore size 0.07 µm removal E. Coli was 99.8%, turbidity 52.9 %, Organic permanganate value 17.6%, and Microplastics 37.1%. The productivity of microfiltration membranes is more significant than rapid sand filters. The removal efficiency of WWTP Ngagel was better than Siwalan Panji.

Abstract
Sea level rise is a certainty because of changes in human life that use machines so that it produces pollution that increases global warming which can make the polar ice caps melt so that the volume of sea water increases. The impact of sea level rise includes changes in coastline, tidal flooding and other impacts that can reduce the quality of life of the community. Surabaya is the second big city on the island of Java after Jakarta which has a population of 2,878,314 people based on the results of the 2020 BPS population census. Of course, this automatically makes the city nicknamed the city of heroes an important city in Indonesia. Therefore, the Geospatial Information Agency as one of the agencies providing tidal data has placed one of its observation stations in the city of Surabaya, located in Ujung Village, Semamir District, Surabaya City, at coordinates 07° 12’ 0.1” South Latitude 112° 44’ 26.1 ” East longitude. The results of data processing using the smallest smoothing method resulted in the LAT tidal datum values, namely -0.636 m, MSL 1.131 m and HAT 2.850 m. The tidal type at the Surabaya tidal station is a mixed mixed tide type which tends to double daily, with an average tidal harmonic constant value of O1 = 0.265 m, S2 = 0.230 m, K1 = 0.476 m, and M2 = 0.377 m. The most dominant tidal harmonic constant is M2, and the lowest harmonic constant is M4 while sea level rise in the city of Surabaya based on the analysis of tidal observation data for 9 (nine) years is 0.199 mm/month.

Published: December 2022

Abstract
Even though the management operation guidelines have been determined, the optimal management of the Citarum Cascade Reservoir has not yet been achieved. Optimal management of cascade reservoirs in an integrated manner is difficult to be carried out due to complex operating procedures and high uncertainty of hydrological components. So, research on the optimal management of each reservoir considering the discharge forecasting model as input discharge (Qin) was proposed. The objective of this study was to optimize Cirata Reservoir’s operational management. Hence all raw water demands are met without any water wasted through the spillway, as indicated by the correlation between inflow discharge (historical and model) and the correlation between trajectory (guideline and actual). In this case, discharge forecasting methods used were Discrete Markov and ARIMA. The continuous with five years return period (R5 continuous), continuous with ten years return period (R10 continuous), 3-classes Discrete Markov, and 5-classes Discrete Markov methods were applied for guideline trajectories. Based on the results, the correlation coefficients between inflow discharge were 0.63 (3-Classes Discrete Markov); 0.78 (5-Classes Discrete Markov); and 0.68 (ARIMA (1,0,0)(1,0,1) & ARIMA (0,0,2)(1,0,1)). Optimization simulations were carried out for 16 scenarios with combinations of four discharge models and four guideline trajectories during the 2016-2020 period. Based on the research, the scenario by the 5-Classes Discrete Markov discharge model and the R10 continuous guideline trajectory is the most optimal management of the Cirata Reservoir, with a correlation coefficient between the trajectory was 0.91.

Abstract
With the ambition to achieve the Sustainable Development Goals (SDGs) agenda in 2030, many countries are increasing the implementation of green financing through green bonds. The question is, how appealing are green bonds for investors? This question is relevant as green bonds have been applied in some countries to help them to achieve sustainable development goals as part of sustainable finance. This paper compares the green bond yield, and conventional bonds yield to see if there is a significant difference between them. This becomes important as the environmental aspect is not the only consideration for investors in choosing green bonds. However, they also pay attention to the return value. The analysis was carried out on the performance of green bonds against conventional bonds in Indonesia from 2018 to 2021 and compared green bonds’ yields with conventional bond yields with an independent sample t-test. The results show that Indonesian green bonds have an increased performance every year and green bond yields have no significant difference from conventional bond yields, where green bonds have slightly higher yields.

Published: December 2022

Abstract
From 2016-2018 there were 120 fuel station accidents in Indonesia. Fuel station accidents may harm not only workers but also the public. Major accidents in fuel stations have caused multiple fatalities and injuries. Various research regarding fuel stations has been done, but research on the role of the community in preventing fuel station accidents is limited. Therefore, studying the cause and effect of fuel station accidents is essential. The study aims to collect accident information and determine the impact, cause, and possible prevention programs for fuel station accidents. Study methods use data collection and classification, followed by qualitative analysis. Data were collected from the top 10 national news portals and tabulated in a structured manner. Twenty-nine fuel station accidents were identified and evaluated. These data were then categorized and analyzed to obtain the dominant effects of accidents. Accident causes were also investigated to provide an understanding and propose accident prevention programs adopted from previous research in various fields. It is concluded that fuel station accidents in Indonesia are dominated by vehicle fires, which involve consumer vehicles. The causes of accidents vary, but most of them were concerning the technical condition of vehicles, and a few were unsafe operations. To prevent future accidents, it is essential to ensure compliance with regulations and standards of facilities and equipment. Furthermore, community involvement is also crucial. Therefore, more efforts are needed to increase public awareness of fuel station hazards and how the community can be involved in preventing future accidents.

Published: December 2022

AbstractDuring the Nyepi celebration, within twenty-four hours, the island of Bali is wholly rested from various activities and business. This study analyzes how the implementation of the Nyepi Holy Day celebration has a broad impact on efforts to save the environment, which is a world issue. Data was obtained through observation, interviews, and literature studies examining Balinese environmental data. Through thematic analysis and interpretation, the Nyepi celebration significantly impacts efforts to protect nature and the environment in Bali. It is closely related to four Nyepi prohibitions, known as Catur Brata Penyepian:Amati Geni, Amati Lelanguan, Amati Lelungan, andAmati Karya. With these four prohibitions, the island of Bali seems to be a dead island for 24 hours, without noise and electricity even at night. All transportation activities, including airports and seaports, have stopped operating. The data shows that there has been saving in electricity use, a reduction in carbon dioxide gas emissions, fuel saving, and an increase in air quality due to the cessation of all human transportation activities. The Nyepi celebration in Bali and carried out by Hindus in Indonesia has had a tremendous impact on the earth.
Challenges and Chances of Sustainable Construction in Indonesia: Policy Insights
Authors: Hapsari MA , Putri WH , Sarju  
Published: December 2022

Abstract
The construction industry in Indonesia is the fourth-largest contributor to the country’s GDP; however, the industry accounts for one-third of total CO2 emissions. As 71% of Indonesians are expected to live in urban by 2030, building sector emissions are also expected to grow at a 4.5% annual rate. The adoption of sustainable construction is required to balance the needs of the community while minimizing the impact on the environment. In 2017, Indonesia integrated its national development planning with the Sustainable Development Goals 2030. Moreover, infrastructure and policies to support the sustainable construction ecosystem began to be implemented. The research aims to assess whether the policies for sustainable construction have been sufficiently all-encompassing and holistic to be implemented appropriately. The analysis was conducted with the descriptive-analysis method. This study concluded that relevant ministries already supported the policies but struggles with execution arose due to underskilled human resources, ineffective stakeholder collaboration, and regional inequality and disparities. The Indonesian government should take advantage of the post-pandemic momentum and potential for high investment values to carry out extensive socialization and fortify the foundation of policies.

Abstract
The increasingly sloping development of COVID-19 cases cannot be separated from the COVID-19 Free Vaccination Program. The implementation of the vaccination program is oriented towards mass immunity against COVID-19. This is the link between the response and the public health aspect. This study discusses the community’s response to the affective dimension (awareness and expectation) about public health in 100 community respondents in Sidoarjo Regency. This research uses a quantitative method with a descriptive type. Several 100 samples were obtained from the formula for measuring samples developed by Slovin. The results showed that most of the respondents on the indicators of awareness and hope chose the “enough” answer. The rest answered, “poor.” Interestingly, none of the respondents in the two indicators answered “good.” Of course, this is a note for policymakers (government), especially in the free vaccine program, that must be evaluated and further improved to improve the effective response of the community.

Abstract
Over the past two years, the Coronavirus pandemic has affected not only the modern working lifestyle but also has impacted street life by demanding social distance and avoiding closed and crowded places. Since then, the public spaces around the world have been trying to adapt to this new environment. Tokyo, one of the most populated metropolises in the world, known for its small apartments and lively streets, has previously made use of the street as a public space, for instance, some commercial Streets in Tokyo are enjoyed as an entire sidewalk by sharing the same space with different means of transportation, providing a walkable environment as a sustainable solution for accessibility in the actual city life. This study will clarify some of the necessities of the new streetscape environment, it will contribute to learning from the ephemeral and close relationship of the use of the street as public spaces in the COVID-19 pandemic and before, enlightening safe but lively pedestrian activities as sustainable and dynamic strategies for a constantly changing lifestyle, helping our cities to be resilient in unpredictable situations for the street life of today and the future emergencies.
