Abstract

The tradition of buwuhan, or donation, is integral to Javanese traditional wedding ceremonies. This practice not only functions as financial support but also reflects social values such as collectivism and reciprocity within the community. This study aims at identifying the mental accounting practices involved in the buwuhan tradition during Javanese weddings and to analyse the symbolic meaning of financial management related to buwuhan. The research adopted a qualitative approach using an ethnographic method, with data collected through direct observation, interviews, and analysis of relevant documents. The informants included traditional elders, community leaders, and individuals who had participated in the wedding procession. The main finding revealed that the practice of buwuhan is perceived as a form of kepotangan a social debt or reciprocal obligation. As a result, many households manage their budgets by prioritising the fulfilment of these obligations over other financial needs.

Abstract

The research about the utilization of modified gas-liquid separators in the determination of Hg ions by using the Cold Vapor Atomic Absorption Spectrophotometer (CV-AAS) method has been done. To optimize the measurement results, several parameters that affect the hydride generator have been studied. Some specified essential parameters are the type and concentration of acid, the level of SnCl2 as a reducing agent, sample volume and the analytical performance such as linearity (r), detection limit (LOD) and quantitation limit (LOQ), repeatability (% RSD), and accuracy have been studied. The results of the research showed the gas-liquid separator modified can be used instead of commercial gas- liquid separators. It was showed by the repeatability value as % RSD < 2/3 CV Horwitz values, the LOD was 0.2530 μg/mL, and the LOQ was 0.8432 μg/mL. The accuracy of this method was good shown by a recovery percentage of 101.6%. Based on the result of this research, the modified of gas-liquid separator can be used for the determination https://www.adenomyosisadviceassociation.org/hysterectomy of Hg ions by using the CV-AAS method with valid results

Abstract

This study aims to explore naturally occurring practices of positive reinforcement in the learning process of Mathematical Physics 2 and their impact on students' motivation and understanding. The study employed a descriptive qualitative approach, with data collected through classroom observations, interviews with the lecturer, and student questionnaires. The results show that the most frequently appearing forms of reinforcement included verbal praise, the awarding of additional points, and constructive feedback. Student responses indicate that these reinforcements had a positive effect on their enthusiasm for learning and classroom engagement. However, students also emphasized the importance of transparency and fairness in the distribution of reinforcement. This study provides an initial contribution to understanding naturally emerging reinforcement strategies and their relevance for further development as systematic instructional approaches in higher education.

Abstract

Thermal comfort is one of the key factors in supporting the teaching and learning process in classrooms, especially in tropical regions like Indonesia, which experience high solar radiation intensity. This study aims to analyze the effect of heat radiation from opening areas on thermal comfort in School Building X. The method involved measuring the dimensions of the building's openings and facades to calculate the Window to Wall Ratio (WWR), as well as determining the Solar Factor (SF) and Shading Coefficient (SC) based on SNI 03-6389-2020. The heat radiation value (Qf”) was calculated for the east and west orientations, which receive the most direct sunlight exposure. The results showed that the highest radiation occurred on the west side at 18.91 W/m² and the east side at 16.42 W/m². Meanwhile, the north and south sides had no Qf” value due to the absence of window openings (WWR = 0). The increase in indoor temperature caused by radiation through openings has a direct impact on the thermal comfort of students, teachers, and university students using the classrooms. Therefore, passive design strategies such as shading and the use of low-E glass are highly recommended to reduce heat load and create a comfortable learning environment.

Abstract

MSMEs are the driving force of the community's economy and play an important role in the coffee processing sector. Gupait MSMEs still face obstacles in the roasting process, which is done manually using a hand crank, resulting in unstable temperatures and inconsistent roasting quality. This community service program was implemented using the Participatory Action Research (PAR) method through the stages of observation, socialization, design of a temperature-controlled roasting machine, trial assistance, and operational training for partners. The roasting machine developed has a capacity of 5 kg per roasting process and uses an automatic Temperature Control system. The implementation results showed a significant improvement in the quality of the roasting, with a uniformity level of around 85-90% and no burnt coffee beans, based on visual evaluation from field trials. Additionally, production capacity increased from approximately 1 kg to 5 kg (maximum drum capacity). The assistance also improved partners' understanding of equipment use and maintenance. This program had a positive impact on product quality improvement, process efficiency, and the competitiveness of Gupait MSMEs.
