Abstract

Criminal acts are actions that violate the law and can arise from various factors such as emotions, psychological pressure, and others. Crime rate is a number that indicate the level of crime vulnerability in a certain area at a certain time. Higher crime rates correspond to increased vulnerability in an area, and vice versa. Among various forms of criminal acts, the number of criminal acts and narcotics crimes in Indonesia tends to increase in 2020 and 2021. The aim of the research is to identify the characteristics of crime rate data based on the number of decency and narcotics incidents in Indonesia using a nonparametric regression approach. This research uses a nonparametric regression method spline truncated and linear regression as comparison. It was found that West Papua Province has the highest crime rate, based on a comparison between linear regression model and truncated spline nonparametric regression model, it can be concluded that the best model is the truncated spline nonparametric regression model with a Generalized Cross Validation (GCV) of 2468.487 and a coefficient of determination of 0 .7389091, indicating that approximately 73% of the variability of the dependent variable can be explained by the independent variables included in the model.

Abstract

The city of Mataram, the capital of West Nusa Tenggara province, consists of 6 sub-districts and 50 sub-districts and has 28 public and private high schools. Lecturers and students of the Department of Chemistry, who are members of the community service team, on August 5th, 2023 carried out a workshop for chemistry and biology teachers in the City of Mataram. The title of the activity was "Application of Phytochemical Screening as a medium to increase the insight of Biology and Chemistry High School Teachers in Mataran City, NTB as an alternative implementation of Merdeka Belajar". The workshop was held at SMAN 5 Mataram City involving 51 chemistry and biology teachers as participants. The material provided includes Phytochemicals and the Chemdraw application. Both of these topics are given by lecturing and discussion and also complemented by practical activities. The successful of the activity is reflected in the increase in posttest scores compared to the pretest score. Evaluation of activities in the form of filling out the questionnaires by participants also reflected the participant satisfaction, in which the majority of participants gave positive answers to each question. Similar activities remain relevant and still need to be carried out, especially in areas outside Java to broaden teachers' insight

Abstract

The coastal community of Sine Beach, Kalibatur Village, Tulungagung, Indonesia, has long thrived on fishing activities. In response to this, a community development service explores the alternative utilization of coconut, particularly the production of Virgin Coconut Oil (VCO), as a means of economic diversification. By integrating scientific principles with local traditions, the community learned to extract VCO and create various coconut-based products. This initiative not only broadened economic horizons but also fostered environmental sustainability. The programs aims to give economic impact to residents in Pantai Sine Tulungagung.
