Abstract

The city of Semarang is a city that is increasingly developing and is pursuing policies to become a decent, safe and livable city. However, cases of violence still occur and have even increased. The efforts made are to provide education and assistance to the community, with the hope of providing understanding and improving morals. The existence of the situation, the efforts of the City of Semarang to create a safe situation but it turns out that it still occurs and even the number of cases of domestic violence has increased, raising the question of how society perceives violence. When it is shown that most of the perpetrators are those closest to them, even their own parents, another question arises, namely whether society, especially, has learned and understood their social roles in the family, whether as father, mother, wife, husband, and/or other social roles. Coupled with the condition as an adult human being which should also be increasingly mature in terms of religiosity, this also raises the question of whether religiosity still has an influence on perceptions of domestic violence. The results of the research analysis show that the magnitude of the relationship between Religiosity and Social Roles and Perceptions of Domestic Violence has a correlation coefficient value of 0.542 with a sig value = 0.000, meaning that there is a very significant relationship between Religiosity and Social Roles and Perceptions of Domestic Violence so that the hypothesis is accepted. Meanwhile, the simultaneous contribution of Religiosity and Social Role to Perceptions of Domestic Violence is 29.4% and 70.6% determined by other variables

Abstract

This method provides direct experiences to students through practical activities aimed at allowing them to feel and understand concepts authentically. Previous research has shown that the practicum method is effective in improving students' understanding and learning outcomes in various learning contexts, such as biology and natural sciences. Additionally, this method has proven to increase students' learning motivation, including in online learning. Therefore, this study aims to evaluate the effectiveness of the practicum method on students' learning outcomes in the subject of natural sciences, specifically focusing on the topic of food and nutrition in class VIIIB at SMP Negeri 3 Segedong, Mempawah Regency. The research method employed is an experiment using paired-sample t-test to measure significant differences between pre-test and post-test scores. The results indicate a significant influence from the implementation of the practicum method on the topic of food and nutrition in the classroom. Data analysis, including normality tests and paired-sample t-tests, indicates that the data is normally distributed, and there is a significant difference between pre-test and post-test scores. Furthermore, the measurement of the effectiveness of the practicum method using N-Gain shows an effectiveness level of 57.8968, which can be concluded as reasonably effective. This research provides insights into the utilization of the practicum method in achieving the goals of natural sciences education, specifically in the context of food and nutrition. These findings can serve as a valuable reference for educators in choosing effective teaching methods to enhance students' learning outcomes

Abstract

This research emphasizes Human Resource Development Performanceexistence which is not as expected, one of the causes is the OHS Management System. Our research aims to explain the performance of human resource development by looking at the impact of Occupational Health and Safety systems, work stress caused and how motivational the role of management is. This research was conducted to produce a Model and the results of the analysis of the Occupational Health and Safety System (OHS MANAGEMENT SYSTEM ) associated with HR Development Performance, with 80 research subjects as employees of PT.PLN Pesero APD Central Java and DIY. This research used quantitative research methods that use Descriptive Statistics and analysis of the effect of each variable using the Partial Least Square (PLS) technique. Based on the results of the calculation of Q square obtained Q square value of 0.60. This showed that the Q square value was greater than 0.5 which means it could be said that the factor of OHS management system, Work Stress and OHS Management Motivation has a good prediction level on the Performance of Human Resources Management. The disadvantage of this study is that because the employees are employees of PT PLN Pesero APD Central Java and DIY, the location of the study always changes depending on the working area. In addition, working conditions and situations greatly affect when subjects fill out questionnaires, bearing in mind that their assignments are very heavy because they are related to the regulation of the electricity load for the Network throughout Indonesia.

Abstract

Micro Small and Medium Enterprises (MSMEs) is a buffer of the national economy that it proved able to survive during the monetary crisis in Indonesia in 1997-1998. On the one hand, MSMEs have a strong resilience to the economic crisis. On the other hand, the development of MSMEs is faced with complex problems. This research departs from the complexity of the problems faced in developing Tapioca Starch business. This study aims to understand the problems faced by SMEs in developing Tapioca Flour Business in Kediri and prepare concrete steps to solve the problem. This research used descriptive qualitative method with data collection technique of interview, observation, and documentation. The results of this study indicated that the problems faced by the Tapioca flour business in Kediri are that they have no the formation of the business in a business group, the lack of human resources skills in developing the business, the limited business capital, and the dependence of the entrepreneurs on the middlemen directly and not to the detriment of entrepreneurs. The steps proposed for such issues include the formation of business groups, strengthening cooperative networks with business groups, markets, and cassava growers, and strengthening venture capital through saving and loan systems.

Abstract

Abstrak Aftercooler merupakan salah satu component pada air system yang berfungsi untuk menurunkan temperature udara bertekanan pada component turbocharger yang akan masuk ke combution chamber, aftercooler dengan jenis jacket water aftercooler (JWAC) jauh lebih efisien dalam perpindahan panas dan kinerja menurunkan temperature secara keseluruhan dibandingkan dengan air to air aftercooler (ATAAC). Keunggulan ini disebabkan oleh karakteristik perpindahan panas air sebagai medium pendingin yang lebih baik. Sistem air to water menghasilkan suhu udara masuk yang lebih rendah, kepadatan udara yang lebih tinggi yang berarti lebih banyak molekul oksigen masuk ke dalam combution chamber yang mengoptimalkan percampuran udara dan fuel yang seimbang dan pada akhirnya, efektivitas aftercooler yang lebih besar. Perbedaan efek pendinginan ini menyebabkan jacket water aftercooler mempertahankan kepadatan udara yang lebih tinggi. Dengan menurunkan temperature udara bertekanan secara efektif, aftercooler dengan sistem air to water membantu mencegah terjadinya knocking, memungkinkan pembakaran bahan bakar yang lebih sempurna, dan berpotensi meningkatkan kinerja unit alat berat. Kata kunci: Aftercooler, ATAAC, efektif , JWAC, temperature

Abstract

Fuel consumption in motorized vehicles is one of the main indicators of the efficiency of land transportation systems. Besides being determined by vehicle technical specifications and driver behavior, fuel efficiency is also significantly influenced by infrastructure conditions, particularly road geometry. Road geometry encompasses elements such as gradient, horizontal and vertical curvature, lane width, and road surface quality, all of which affect vehicle dynamics while driving. Roads with suboptimal geometric designs can cause increased engine workload, inefficient acceleration, and repeated deceleration, ultimately resulting in fuel waste. This study aims to examine the extent to which road geometric elements affect motorized vehicle fuel consumption. Through a literature-based qualitative and quantitative analysis approach and technical evaluation, it was found that efficient geometric design can significantly reduce fuel consumption. These findings emphasize the importance of integrating energy efficiency aspects into road planning and design processes to create a land transportation system that is not only effective and economical, but also sustainable and environmentally friendly. Keywords: Road design, energy efficiency, road geometry, fuel consumption, land transportation
