Abstract

In the component manufacturing process in the automotive industry, product quality control strategies affect product defect detection and traceability, production costs, and customer delivery times. To support the achievement of quality assurance in production conditions and production delivery schedules, determining the inspection method of the Pitch Circle Diameter (PCD) on brake drum components becomes important if the operational process capability of the machine is low at Cp = 0.89 and Cpk = 0.83, along with the degradation and age of the machine. The strategy for selecting the use of a Coordinate Measuring Machine (CMM) or a limit gauge for a 100% inspection tool based on the OK/NG classification is evaluated from the aspects of effectiveness, accuracy, and time efficiency. From the evaluation method of the Measurement System Analysis attribute type, specifically Attribute Agreement Analysis, a total of 30 samples were tested by three operators with three replications. The evaluation results showed the effectiveness of the limit gauge of 95.18%, a miss rate of 0%, and a false alarm rate of 7.69%. The Fleiss' Kappa value of the use of the limit gauge was 0.90, indicating good and consistent measurement suitability between operators. Limit gauges showed a measurement time that was 97.7% faster than a CMM (Coordinate Measuring Machine) (17 seconds vs. 740 seconds). The study showed that the strategy of making and using limit gauges as the primary inspection was effective for the need to check 100% of components, under production conditions, with a CMM as a periodic sampling inspection.

Abstract

Pancasila memiliki kedudukan fundamental dalam kehidupan berbangsa dan bernegara, yaitu sebagai dasar negara, pandangan hidup, dan ideologi nasional. Artikel ini bertujuan untuk menjelaskan nilai-nilai dasar Pancasila serta butir-butir pengamalannya dalam kehidupan sehari- hari. Penelitian ini menggunakan metode kualitatif deskriptif dengan pendekatan studi kepustakaan, dengan data primer berupa dokumen resmi negara dan data sekunder berupa literatur akademik yang relevan. Hasil penelitian menunjukkan bahwa Pancasila memuat nilai religiusitas, kemanusiaan, persatuan, demokrasi, dan keadilan sosial yang bersifat universal sekaligus kontekstual. Butir-butir pengamalan Pancasila merupakan penjabaran operasional yang memudahkan penerapan nilai-nilainya dalam berbagai bidang kehidupan, baik individu maupun sosial. Dalam konteks globalisasi, pengamalan Pancasila menghadapi tantangan berupa intoleransi, krisis solidaritas, dan praktik politik yang pragmatis. Namun, Pancasila tetap relevan sebagai filter nilai global sekaligus peneguh identitas bangsa apabila diinternalisasikan melalui pendidikan, kebijakan publik, dan praktik sosial. Dengan demikian, Pancasila tidak hanya menjadi ideologi normatif, tetapi juga pedoman praktis dalam membangun masyarakat yang adil, demokratis, dan bermartabat.

Abstract

Thermal Energy Storage (TES) systems are essential for managing low-grade heat in renewable energy applications. This study evaluates the impact of flow rate and heating power on thermal stratification and efficiency within a 30-liter TES unit. Using an AI-assisted simulation framework, the system's performance was analyzed across varying flow rates (0.3–0.9 LPM) and heater capacities (1.5–2.0 kW). Results indicate that lower flow rates (0.3–1.2 LPM) effectively preserve stratification, whereas higher rates induce thermal mixing. While charging efficiency generally decreases as target temperatures rise, it improves significantly with higher heater power. Notably, the configuration using a 0.7 LPM flow rate and 2.0 kW heater achieved a peak efficiency of 78% while maintaining stable thermal layering. This research demonstrates how AI-driven modeling can optimize charging behavior, providing critical insights for the design and thermal management of compact TES systems in low-grade heat applications.

Abstract

The strategy and effort to build villages accommodate village activists to create collective learning spaces in village resource governance. Village initiatives and capabilities in managing existing resources in their areas are the basic capital to create strong, advanced, and independent villages. Literacy in the form of information technology is a learning tool that can bridge village activists in various regions through relevant and sustainable community service program interventions to reduce and minimize the presence of poor communities in villages. Gorontalo Province is ranked 6th out of 10 regions with the highest number of poor people in September 2023 (BPS, January 2024), with a poor population of 15.41 percent and Central Sulawesi is ranked 10th with a percentage of poor people of 12.18 percent. The distribution of poor population areas is found to be in the Tomini Bay area. The Thematic KKN Program by LPPM UNG in 2025 is oriented to improve the quality of the number of community service of UNG lecturers. Providing solutions to partner problems with a holistic approach based on multidisciplinary research that has been implemented and is able to be effective for the priority scale of community development in the 3T region as stated in Presidential Decree No. 63 of 2020 and based on BPS data in 2021. The target of the community-based social literacy empowerment program to support the development of local food economic independence through this Thematic KKN program is the realization of a community that has good knowledge and understanding of social literacy as part of the learning process and has skills that are an effort to improve welfare through economic independence and local food security of the community. The type of literacy development developed is a community-based potential that is worth exploring (village) that is available and has comparative advantages and competitive advantages both economically, socially and environmentally that can be produced and marketed in order to create community economic independence through a local food security program.
