Abstract

The bypass system in spin-on type oil filters plays a crucial role in maintaining engine cleanliness and performance by allowing oil to flow when excessive pressure occurs. A critical component of this system is endplate-B, which fulfills dual roles: providing structural support and functioning as an interface for oil passage during bypass operations. However, the relatively high material usage and cost associated with the current design of endplate-B pose challenges in manufacturing efficiency. The objective of this study is to minimize the material cost of endplate-B by optimizing its dimensional geometry without compromising its structural and functional performance. The research methodology encompasses dimensional redesign, structural analysis, and performance validation under simulated operating conditions. The findings indicate that strategic dimensional modifications can substantially reduce material usage while preserving mechanical strength and functional integrity. The implementation of this optimized design provides a cost-effective solution for the manufacturing of oil filters and contributes to broader efforts to improve production efficiency in the automotive component industry.

Abstract

The Marengan River serves as a critical freshwater resource for local residents; however, escalating human-induced activities have contributed to its declining water quality. This research aims to evaluate the river's water quality status through an analysis of water quality indicators and a pollution index assessment. The methodology included field observations, water sampling at five selected points along the river, and laboratory examinations measuring BOD, COD, TSS, DO, nitrate, phosphate, and total coliform levels. Findings revealed that BOD and COD concentrations at all locations surpassed the environmental quality standards, with the third sampling point exhibiting the most elevated levels. The calculated Pollution Index values ranged between 5.24 and 7.85, categorizing the river as moderately to heavily polluted. Key pollution contributors are presumed to include household wastewater, agricultural discharge, and organic matter. The study concludes that urgent action is needed to address the environmental degradation of the Marengan River, through wastewater treatment implementation, watershed area restoration, and active community participation. These interventions are recommended to foster sustainable river basin management and improve overall water quality.

Abstract

Calcium oxide (CaO) is the result of the combustion of calcium carbonate (CaCO3) through a calcination process. It can be utilized as an adsorbent. CaO has been demonstrated to be an effective adsorbent in a variety of applications, particularly in the domains of purification and waste treatment. The presence of calcium carbonate has been observed in various types of shells, including those of eggs and shellfish. The objective of this study is to analyze the calcium oxide produced in the shells of duck eggs, quail eggs, green mussels, rice paddy snails, and kupang. The study will employ XRF analysis to determine the shells that produce the highest calcium oxide. The present study employed a combustion time variation ranging from 24 to 120 minutes at an elevated temperature of 800°C. The results demonstrated that duck eggshells calcined for 120 minutes exhibited the highest calcium oxide content. Subsequent analysis using scanning electron microscopy (SEM) and UV-Vis spectrophotometry was conducted to ascertain the morphology and adsorption power. Consequently, the processing of shell waste has the dual benefits of reducing environmental impact and generating higher economic value through its utilization as an adsorbent.

Abstract

The tobacco industry is a strategic sector that significantly contributes to the national economy; however, its operations also generate hazardous and toxic waste (B3) that poses a risk to the environment. The objective of this study is to evaluate the B3 waste management system that has been implemented by PT. XYZ, with a particular emphasis on the reduction and management of waste, with a focus on storage practices. A descriptive methodology was employed, combining direct observation and document analysis of existing conditions, which were then compared against the provisions of the Minister of Environment and Forestry Regulation No. 6 of 2021. The evaluation employed a Likert scale to assess the level of compliance with the regulations. The findings indicated that PT. XYZ has been identified as a producer of nine distinct categories of B3 waste, with the primary sources of these materials being attributed to various production activities and maintenance procedures involving machinery. The waste reduction aspect achieved a compliance score of 62.5%, which is categorized as "Good," while the storage aspect reached 95.45%, which is categorized as "Very Good." The overall score was determined to be 78.97%. These results suggest that, despite the effective implementation of waste storage practices, enhancements are necessary in the domains of reporting and the utilization of waste reduction technologies, with the objective of aligning with the principles of sustainable development.

Abstract

In the context of endeavours to furnish adequate housing, the term "housing" is understood to denote a collection of dwellings situated within a communal environment that has been furnished with amenities, infrastructure, and public facilities. The Indonesian government has implemented a subsidised housing programme targeted at low-income individuals (MBR) to address the nation's housing needs. The objective of this study was to ascertain the extent to which subsidised housing type 36 in Katingan Regency is influenced by facilities, price, building quality, location, income, and promotion.  The present study employs a survey approach, which involves the collection of data from subsidised homeowners through the administration of questionnaires. The study surveyed 100 research respondents. The research data analysis employed structural equation modelling and partial least squares. The findings of the analysis demonstrate that variables such as income, price, location, building quality, and promotion exert negligible influence on purchasing decisions. However, it is evident that facility and promotion variables do have a significant impact on purchasing decisions. The final model demonstrates that the variables studied contribute 80% to the purchase decision, with the remaining 20% influenced by variables not covered in this study. This is evidenced by an R2 value of 0.807.

Abstract

The assessment of concrete's compressive strength is of paramount importance in determining the quality of the concrete mixture and its subsequent curing process. The utilisation of water with an optimal pH level during the mixing process has been demonstrated to yield concrete of a superior quality. Despite the abundant water present in peat areas, the pH of this water is typically below ±7. Consequently, further research is necessary to ascertain the suitability of this water for use in concrete mixing. The methodology employed in this study is a quantitative descriptive study that aims to determine the impact of water with a low pH from peat areas on the concrete mixture on the resulting compressive strength. The study commenced with a review of the extant literature, followed by the testing of the concrete quality plan of 23 Mpa using water with a pH of 5.51. The curing process was conducted on days 7, 14, 28, and 90. The findings of the compressive strength examination demonstrated values of 13.1 MPa at the age of seven days, 15.3 MPa at the age of 14 days, and 15.2 MPa at the age of 28 days. Thereafter, a decline was observed at the age of 90 days, resulting in an average compressive strength of 11 MPa. The findings of this study suggest that water with a pH below 7 has a detrimental effect on the quality of concrete.

Abstract

The rapid growth of the laundry industry in Indonesia, recorded in 2021 there were more than 30,000 laundries spread throughout Indonesia with a business growth of 15-20% per year (Bisnis et al, 2021) the increased laundry industry means more wastewater will be produced. If it is not treated properly before being discharged into water bodies, it can pollute water bodies and the ecosystems inside. One of the processing methods is the Moving Bed Biofilm Reactor (MBBR) which is a biological method by utilizing microorganisms to form a biofilms and stick to carrier media and then move dynamically so that contact occurs between waste and microorganisms effectively which can degrade pollutants in laundry waste, the more bacteria added and the longer the contact time, the more pollutants will be degraded. In this study, variations in the addition of Pseudomonas aeruginosa bacteria were carried out by 0%, 3%, 5%, 7% and 10% with contact times of 7 hours, 14 hours, 21 hours and 28 hours to degrade COD, phosphate and detergent parameters in laundry wastewater. The greatest removal efficiency was obtained at the addition of 10% bacteria and a contact time of 28 hours, namely 84% COD, 96% detergent and 74% phosphate. The number of colonies in the biofilm with the addition of 0% was 101,000 CFU/mL, 3% was 110,000 CFU/mL, 5% was 184,000 CFU/mL, 7% was 234,000 CFU/mL and 10% was 338,000 CFU/mL.
