The objective of this study is to assess the quality of the Cenrana River water as a potential drinking water source for a community in the Cenrana watershed Wajo, as well as to evaluate the effectiveness of a basic water purification system in improving its condition. Cenrana River is located in the Maros Regency and Bone Regency, South Sulawesi Province, Indonesia. The study was conducted at the Laboratory of Material Testing, Faculty of Engineering Universitas Negeri Makassar, and the Makassar Health Laboratory Center. Water samples are taken in the Walanae River located in Bone Regency and tested in the abovementioned laboratory. This type of research is experimental, which involves assembling a simple clarification tool in the material testing laboratory, and then raw water is purified with the device. Water samples, both raw water and purified water, are tested at the Makassar Health Laboratory Center. The data analysis used is qualitative descriptive, which compares the results of laboratory tests of raw water that have not been clarified and the results of laboratory tests of water that have been purified with the parameters of clean water standard criteria based on the regulation by the Ministry of Health of the Republic of Indonesia. The results showed that although the water had been cleaned through two filters, several parameters tended to increase from the previous year's test results with one filter, such as the No2 content from 0.017 to 0.034, No3 from 0.01 to 0.39, dissolved solids from 152 to 156, Fe from 0.01 to 0.17, Mn from 0.01 to 0.15, SO4 from 14.39 to 15, 54, and Ammonia from 0.05 to 0.29 even though it still meets the standards of the Ministry of Health of the Republic of Indonesia. In addition, the raw water coliform content also increased from an average of 6,600/100 ml in 2016 to 20,050/100 ml in 2019. This means that there is a tendency for Cenrana River water pollution may increase every year.

Mechanical parts on ships and automobiles are diverse in shape, size, and working conditions. They operate with static, cyclic, and shock loads in various environments at low and high temperatures. Therefore, materials need to be highly durable to ensure the reliability of parts and structures on ships and automobiles. Currently, materials used in the shipbuilding and automotive industry are diverse, and steel is commonly used. Therefore, the shipbuilding and automotive industry requires increasingly higher steel mechanical properties. Among the advanced high-strength steel families, low Mn steels with phase change, thanks to the plastic deformation process, are steel lines with high durability, flexibility, and good fatigue resistance. Therefore, low Mn steel is suitable for manufacturing load-bearing parts that undergo deformation to create the required shape. This work presents general studies on the effects of some elements, such as Mn, Si, and C, on the microstructure and mechanical properties of TRIP steel. This article also presents the mechanism of the phase transformation process of TRIP steel when heated and cooled under some conditions, the thermodynamic basis of the formation of TRIP-type bainitic ferrite steel structure, and the influence of C, Mn, and Si on the formation kinetics of TBF steel structure. Through these review studies, the article synthesizes and identifies a number of phase transformation mechanisms for steel; the influence of certain alloying elements on the microstructure and mechanical properties of steel has been determined.

Implementing Building Information Modeling (BIM) in Indonesian construction can potentially optimize material resources, labor, and energy efficiency. However, several challenges hinder its effectiveness, including proficiency, standards, policies, infrastructure, and BIM access. This research aims to identify and address factors impeding BIM implementation, providing recommendations for stakeholders to impact the construction industry positively. Conducted through a quantitative approach, the study gathers data online via questionnaires distributed among BIM stakeholders, encompassing practitioners, academics, and government representatives. The data is meticulously analyzed using ANOVA, factor analysis, and factor rotation techniques. The research identifies five key factors contributing to BIM issues in Indonesia based on eigenvalues exceeding 1.0. These factors encompass limited BIM access, challenges in proficiency and mastery, incomplete data on components and materials, inaccessible BIM infrastructure, and restricted collaboration across domains. The users' expectations center around BIM dissemination and standardization, easy data accessibility, establishing a robust Indonesian BIM community, affordability and accessibility of BIM infrastructure, and user-friendly BIM platforms. The anticipated outcomes of this research offer practical implications for the construction industry. These include recommendations for enhanced BIM training, proposing government funding to facilitate companies in acquiring necessary BIM software and hardware, and promoting BIM knowledge through seminars. The overarching goal is to address the identified challenges, fostering efficient BIM utilization in the Indonesian construction industry.

Railway infrastructure maintenance is essential in implementing the transportation system. Most of these railway bridges have suffered gradual deterioration over time. Predictive structural health monitoring (SHM) is required by installing instrumentation sensors on railway bridges to determine the condition of the railway bridge infrastructure at the site. This research aims to analyze and assess the existing condition of steel railway bridges to understand the load-deformation characteristics, bearing capacity, and dynamic response of the structure. This paper describes a valuable method for assessing the condition of steel railway bridges during operation. This paper presents a direct analysis of the steel railway bridge structure, with a span of 40.00 meters, a width of 4.40 meters, and a height of 6.60 meters. The steel structure railway bridge is modeled in 3D in detail, and numerical analysis is carried out using finite element analysis based on input parameters obtained from manual field measurements and instrumentation sensors. The expected result of the development of this SHM System is to know the performance of the steel railway bridge structure in real-time via the dashboard display. The results showed that the carrying capacity of the railway bridge was in a relatively safe condition. This case study may help practice engineers and researchers in future research. It can be a valuable reference for future research in developing and applying such a system to a typical case.

Meso-and microforming is a technology to shape parts from extremely small metal billets. Parts with geometric dimensions are a few millimetres to a few micrometres. With the rapid development of the electrical-electronics industry and biomedical engineering, the technology of forming microscopic parts has been researched and applied because of its efficiency, accuracy, and high productivity. Deep drawing is an operation that turns flat sheet metal blanks into hollow, open-mouth parts. It is an essential process in sheet metal stamping. Micro deep drawing is one of the micro-shaping technologies that has been widely studied and applied in recent years. However, the bases for calculating technological and geometrical parameters in the micro-deep drawing have not yet been analyzed and evaluated in detail. Therefore, this paper has proposed a theoretical basis combined with simulation applied to the design of technology to manufacture a connector head part drawing die with a diameter of 300µm and height of 1500µm using materials SUS304 material. Numerical simulation also allows evaluation of the stamping part's internal stress state, the ability to pull the workpiece into the die, and the thickness distribution on the product wall. Experimental research has also verified that, with the determined parameters, the stamping parts meet the quality requirements. This indicates the proposed calculation methods for the tiny deep drawing operation are entirely suitable. The results of this research can be wholly applied to the production of micro-sized cylindrical cup parts using the deep drawing method.

Electric bicycles, also known as e-bikes, are future bicycles with an electric motor as a locomotive. Electric bicycles using rechargeable batteries can go from 25 to 32 km/h, while more powerful varieties can go more than 45 km/h (28 mph). The research method begins with making an electric bicycle with a 350-watt BLDC motor powered by a 36 V 21 Ah battery, which theoretically will get up to 2 hours of battery use at maximum speed. The test was carried out in terms of travel speed fuel consumption on flat or uphill road conditions. After all the tests have been completed, data on the results of the performance of the electric bicycle can be obtained, and then a graph of the performance characteristics of the electric bicycle can be made. After conducting data analysis based on the graph of the performance characteristics of this electric bicycle, it is concluded that the use of the smallest gear is effective when the electric bicycle is starting, but the low speed and the largest gear are used when the motorbike is running to get a high speed of 32 km. The success of this research will impact Reducing dependency on fossil fuel vehicles.

Biomass, noted for its adaptability, has various applications in biofuel generation, industrial use, and environmental cleaning. This study looks into the multiple roles of biomass as a renewable energy source, with a particular emphasis on its vital contribution to biofuel production. Through a thorough evaluation of different conversion routes—thermal, biological, and physical—the study emphasizes thermochemical processes' efficiency, cost-effectiveness, and adaptability. Notably, technologies like gasification and quick pyrolysis are thoroughly investigated, followed by in-depth discussions of reactor optimization strategies to enhance performance and output. The complex structure of biomass, which is dominated by high-molecular-weight polysaccharides such as cellulose and hemicelluloses, demonstrates its significant potential for energy generation. Furthermore, the study categorizes biomass by content, origin, and conversion processes, resulting in a comprehensive inventory of available resources. Biomass from the agriculture and forestry industries, such as starch, sugar, lignocellulose, and organic wastes, is rigorously analyzed for energy production. Furthermore, various biomass processing techniques, including thermochemical, biochemical, and physicochemical conversions, are carefully tested in real-world applications to ensure their efficacy and viability. Beyond its importance in biofuel production, the article underlines biomass' versatility in satisfying industrial needs and contributing to environmental cleanup initiatives. This study lays the groundwork for informed decision-making and innovative solutions in various industries by providing a thorough understanding of biomass's various benefits and applications, including energy provision, industrial processes, and ecological restoration.

The low availability of health services in disadvantaged areas raises conventional medicine as an alternative. The study aims to analyze the factors related to traditional health services (THS) utilization in disadvantaged areas in Indonesia, based on Presidential Regulation Number 63 of 2020 concerning the Determination of Underdeveloped Regions for 2020–2024. The research employed data from the 2018 Indonesian Basic Health Survey. This cross-sectional survey analyzed 16,346 respondents. The study looked at THS use as a dependent variable and six independent variables (age group, gender, marital status, education level, occupation type, and wealth status). We employed binary logistic regression to analyze the data. The results showed that Indonesia's average THS utilization in a disadvantaged area in 2018 was 17.6%. Meanwhile, the study found that age group, marital status, occupation type, and wealth status were related to THS utilization in a disadvantaged area in Indonesia. The older a person is, the more likely he is to utilize THS. Those who are married were more likely to use THS than unmarried. The study also found that work type and wealth status were related to THS utilization. The study concluded four factors associated with THS utilization in a disadvantaged area in Indonesia: age, marital, occupation, and wealth. We need further qualitative studies about the reasons why people choose THS. This follow-up study is vital for policymakers to develop THS according to the needs of their consumers.

In Ecuador, rural housing in the Andean region has limitations in its implementation and construction, which lacks technical criteria. This is due to scarce research considering the geographical and climatic conditions and the characteristics of construction materials suitable for this type of housing. This study analyzes the thermal comfort of two cases of study located in the Province of Cotopaxi, Ecuador. This location's altitude exceeds 2,900 MASL, and the average temperature ranges between 12°C and -3°C. The selected samples are two predominant single-family housing typologies in the region: the first, with a traditional construction system and the second, with a conventional system. This study has three main parts: in-situ data collection with measurement equipment, user interviews, and software simulations to obtain thermal data. The first phase, data collection and interviews, facilitate the analysis of discomfort hours and operating temperature (OT) of the current state of the housing. These first results allowed the second phase of this study, which is simulation. In this part, modifications of materiality and carpentry were proposed. The results show significant improvements in thermal comfort. Housing 1 increases by 14% of OT, and Housing 2 increases by 23% of O. T. Both study cases show a significant reduction in the discomfort hours. This research's main conclusion is that adequate material management through software simulation can contribute to innovative solutions for thermal comfort. The outgoing results of this study can be used in future housing and interventions in the region.

The ongoing climate change resulting from the effects of global warming is manifested through increased variability and a rise in extreme precipitation events. Given this situation, it becomes imperative for farmers to adapt to these changes to ensure the long-term sustainability of their businesses. Therefore, this research aimed to assess extreme precipitation for planning adaptation strategies for agricultural water resources in the Selo watershed, Tanah Datar Regency, West Sumatra Province, Indonesia. Climate Hazards Group Infrared Precipitation and Stations (CHIRPS) data were used to accomplish this, spanning 1981 to 2020. A set of indices recommended by ETCCDI, including PRCPTOT, CDD, CWD, R95p, R99p, SDII, R10mm, R20mm, R30mm, and R40mm were employed to assess extreme precipitation. Climate Data Operator (CDO) and GrADS were conducted for downscale and plotting data. Furthermore, the Mann-Kendall test was conducted to determine the significance of change trends in the indices. R-Climdex was used to determine the extreme event based on the data used. The results showed that all indices indicated wet conditions during the period 1981-2020. The topographic characteristics of the watershed served as a basis for selecting suitable adaptation strategies within the agricultural water resources sector. One potential approach involves integrating conservation-based adaptation practices with comprehensive watershed management techniques. Factors such as the area’s sensitivity to changes in the total intensity or frequency of precipitation, combined with the local environmental conditions, can be considered in determining the optimal adaptation approach.
