Abstract

Population expansion, urbanization, economic development, pollution, and climate change are all contributing factors to the growing global problem of water shortage. The Sustainable Development Goals (SDGs) are in danger of being achieved because of this dilemma, particularly SDGs 6 and 11 on clean water and sanitation and sustainable cities, respectively. Only 65.9% of Jakarta's population has access to potable water, and water stress levels range from 40 to 80%. The government is planning a wastewater treatment system (SPALD-T) to recycle household wastewater and produce clean water in order to address this issue. TB. Simatupang's Water Treatment Plant (WWTP) still faces obstacles in adopting wastewater reuse, nonetheless.  In Indonesia, wastewater recycling has received little attention, with the majority of studies concentrating on technical concerns rather than sustainability considerations. In contrast, technologies such as desalination and rainfall harvesting are being investigated worldwide. The objective of this research is to examine the technical and non-technical elements that affect wastewater recycling's effectiveness for the generation of sustainable clean water. The results will offer crucial information to help Perumda Paljaya create policies that will effectively utilize wastewater, which will help Jakarta accomplish its sustainable development goals more broadly.

Abstract

The current packaging of Rangi Cake products in the market is criticized for its simplicity and lack of adequate safety features, which compromises both product safety and visual appeal. To address this, a research initiative was undertaken to enhance the design and functionality of Rangi Cake packaging. The study employed Kansei engineering to discern consumer preferences regarding packaging. The findings incorporated 46 packaging samples and identified 44 Kansei words. Utilizing Principal Component Analysis (PCA), two design concepts emerged: "Standard-simple" and "informative-efficient." The "standard-simple" concept, with the highest R-Square value of 0.9615 through QTT-1 results, was selected for further development. The design elements derived from consumer preferences include a square shape, kraft cardboard material, window feature, typography design, minimalist style, surface sticker, gray color, and header card/topper cover shape. The packaging design, based on these elements, was translated into 3D mockups. Survey results indicated a preference for the Reusable concept mockup (PC2). Sample evaluation, conducted using fuzzy logic on the PC1 sample, yielded a value of 4.0, affirming the positive reception of the redesigned packaging concept. This research contributes to elevating the visual appeal and functionality of Rangi Cake packaging, aligning it more closely with consumer preferences.

Abstract

The appearance of four-wheeled vehicles is the first aspect observed by customers. Defects in appearance, such as gaps in the rear combination lamps, can reduce the competitiveness of Multi-Purpose Vehicle (MPV) products. Such defects affect product quality and customer satisfaction, making it essential for companies to minimize defects to enhance market competitiveness. This study applies the QCC (Quality Control Circle) method with a PDCA (Plan-Do-Check-Action) approach, supported by the 8-step problem-solving process and 7 QC tools. The method aims to identify the root causes of defects and implement appropriate corrective actions. In its implementation, the Plan phase involves identifying the problem and analyzing root causes using QC tools such as Pareto charts and fishbone diagrams. In the Do phase, corrective actions are carried out by adjusting processes or materials. The Check phase includes evaluating the results of the corrective actions, while the Action phase ensures the changes are sustained over time. Using the QCC method, defect rates per unit decreased from 0.130 to 0.004.

Abstract

The growth of electric vehicles is accompanied by an increase in the number of batteries and battery waste produced, which can ultimately have harmful effects on the environment. As a solution, battery pack remanufacturing has emerged as an effective alternative. However, challenges in the remanufacturing process include determining which battery pack components can be repaired and which require replacement with new components, ensuring that remanufacturing costs remain low while preventing potential future failures. This study aims to develop a remanufacturing decision model that integrates Failure Mode and Effect Analysis (FMEA) with a remanufacturing cost model. The study’s results outline the relationship between failure modes and battery pack components, whereby each failure mode can be classified to determine appropriate repair or replacement actions. While specific actions have been formulated, remanufacturing costs remain the final determinant in the overall battery remanufacturing decision. Based on the analysis, repairs or replacement of new part on 13 components associated with failure modes still render the battery pack suitable for remanufacturing, with a potential cost saving of more than 40% compared to purchasing a new battery pack.

Abstract

This research aims to redesign an ergonomic tourist boat ladder to improve the comfort and safety of tourists in the context of marine tourism. Tanjung Luar Tourism Village, East Lombok, was chosen as the research location due to the high potential of tourists using boats as a means of transportation to marine tourism destinations. Currently, many tourist boats are not equipped with safe and comfortable stairs, increasing the risk of accidents. The method used in this research is Quality Function Deployment (QFD), which identifies the needs and preferences of tourists through surveys and questionnaires. The research sample consisted of 57 respondents, including tourists, boat crew, and ergonomics experts. The House of Quality (HoQ) results showed that the main needs of tourists include comfortable and safe handrails, anti-slip stair surfaces, and corrosion-resistant stair materials. Based on these needs, three alternative boat ladder designs were developed that consider aspects of safety, durability, and ease of use in marine environmental conditions. Products with ergonomic handrails, stainless steel material, and design flexibility were prioritized in the development. These designs are expected to not only provide a safer and more comfortable solution for users but also contribute to the development of safety standards for tourist boats in Indonesia. This research provides a foundation for the improvement of tourist boat facilities, especially in areas with great potential in marine tourism.
