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.

Abstract

Propolis merupakan produk penting bagi lebah yang banyak digunakan sebagai salah satu alternatif pengobatan alami karena mengandung senyawa bioaktif yang dapat memberikan efek positif pada tubuh. Sebagai produk yang dihasilkan lebah untuk menutupi sarangnya dan mencegah predator maupun infeksi bakteri atau virus dari luar, propolis memiliki salah satu manfaat sebagai antibakteri. Penelitian ini bertujuan untuk mengetahui daya hambat ekstrak propolis lebah Heterotrigona itama yang berasal dari 4 lokasi budidaya (perkebunan, persawahan, hutan sekunder, dan perkotaan) di Kalimantan Timur terhadap bakteri Propionibacterium acnes atau P.acnes dengan metode difusi lubang/sumuran pada media nutrient broth (NB) dengan kloramfenikol sebagai kontrol positif dan aseton sebagai kontrol negatif. Propolis diekstrak menggunakan metode maserasi dengan larutan etanol 96% yang kemudian dibuat dalam 3 (tiga) konsentrasi yaitu 500ppm, 250 ppm, dan 125 ppm. Hasil penelitian menunjukanfitokimia dari propolis di 4 lokasi budidaya dominan mengandung alkaloid, flavonoid dan kumarin. Uji bakteri pada konsentrasi 500 ppm,propolis H.itama dari lokasi perkebunan dan persawahan tergolong dalam kategori kuat dalam menghambat pertumbuhan bakteri, dari lokasi hutan sekunder tergolong sedang, dan dari lokasi perkotaan tergolong rendah.

Abstract

The increasing volume of household waste in densely populated residential areas is a major challenge for urban environmental management. Limited waste management systems and low household-level waste-sorting practices lead to the accumulation of organic waste, which could cause environmental pollution. Therefore, a sustainable waste management strategy based on community participation is needed. This community service program aims to implement and evaluate a zero-waste strategy by empowering the PKK Ecomitra group in Wage Village, Sidoarjo, through the use of appropriate technologies, including a Dekomposer Dua Sisi (Dedisi) and biopore holes, for processing household organic waste. The program was implemented using a Participatory Action Research (PAR) approach that actively involved partners in planning, socialization, training, technology application, and evaluation. Evaluation was conducted through pretest and posttest methods on 15 indicators of participant knowledge and attitudes. The results showed a significant increase in understanding of the fermentation process, waste sorting skills, awareness of the zero-waste concept, and the use of biopore holes. The overall program achievement rate exceeded 80 percent of the set target. These results indicate that a zero-waste strategy based on collective community decisions and the application of simple technologies is effective in increasing household waste management capacity and behavior, and in supporting the achievement of SDGs 12 and 13.

Abstract

Media sosial memberikan kemudahan bagi masyarakat untuk mencari informasi, berkomunikasi, dan bersosialisasi, tetapi juga dapat memberi ruang terjadinya pelanggaran privasi terhadap data pribadi pengguna. Akibat teknologi yang semakin berkembang, saat ini telah banyak terjadi masalah mengenai pelanggaran privasi. Masalah mengenai privasi ini tidak memandang usia, termasuk juga remaja akibat kurangnya pemahaman akan kesadaran privasi. Remaja sebagai generasi milenial yang selalu terhubung dengan internet dan media sosial dapat menjadi sasaran dari kurangnya kesadaran privasi. Salah satunya dengan memberikan data pribadi di berbagai perangkat online yang memberi resiko terjadinya penyalahgunaan data pribadi, sehingga perlu diketahui hubungan pengaruh penggunaan media sosial terhadap kesadaran privasi pada remaja di Kota Surabaya. Penelitian ini bertujuan untuk menganalisis hubungan antara penggunaan media sosial dengan kesadaran privasi pada usia dan jenis kelamin remaja di Kota Surabaya. Metode yang digunakan dalam penelitian ini adalah survei dan analisis data menggunakan statistik uji Chi-Square. Hasil penelitian ditemukan bahwa tidak terdapat hubungan antara penggunaan media sosial dengan kesadaran privasi pada usia dan jenis kelamin remaja di Kota Surabaya.

Abstract

Senden Village in Trenggalek, East Java, has rich biodiversity and cultural assets, but limited knowledge and capacity to turn them into marketable products or tourism opportunities. This program aimed to enhance community skills in developing herbal-based products and to increase awareness of educational tourism potential, while fostering intercultural collaboration between villagers and international students. The International Community Service (ICS) 2025 program, involving Universitas Airlangga and partner universities from Indonesia, Pakistan and Malaysia, was implemented through preparatory coordination, hands-on workshops, awareness sessions, and evaluation. Villagers participated in practical training to produce herbal products and also engaged in discussions on sustainable tourism development at Goa Ngerit. The 22 participants who completed the post-activity questionnaire predominantly rated the training as "excellent" or "good," underscoring the activity's relevance, clarity, and practical utility. Overall, these findings confirm that the training outcomes align with the program's indicators and objectives and validate the effectiveness of a participatory, practice-based community training model. ICS 2025 successfully empowered the Senden Village community by combining product innovation and tourism awareness, with recommendations for longer training, post-program mentoring, and stronger stakeholder involvement to ensure sustainability.
