Abstract

Biomass energy, which comes from plants, is used as a heating source in fish processing. This community service activity is focused on the smoked fish processing industry in Air Dingin Village, Bukit Raya District, Pekanbaru, with the aim of analyzing the optimal use of biomass energy. The main source of energy is the rambutan tree trunk, which gives a distinctive aroma to smoked fish. The method used is direct training to apply new techniques in this industry, with raw materials of patin fish (30 kg) and catfish (40 kg). The smoking process takes 24 hours, producing efficient and high-quality smoked fish, seen from its bright color and fragrant aroma. This Community Partnership Program (PKM) aims to improve the quality and quantity of production of the UKM MINA SALAI KUARAN business group. It is hoped that the quantity of production will increase by 50%, while the social aspects of the community are strengthened through online marketing using social media such as Twitter and Facebook. Thus, this business has the potential to become more independent and improve the welfare of the local community.

Abstract

This study aims to analyze efforts to prevent and eradicate corruption in the context of digitalization in Bandar Lampung. The digitalization era brings significant changes in the way government and society interact, which has the potential to create opportunities for corrupt practices. The research method used is a qualitative approach with data analysis from interviews, documentation studies, and observations. The results of the study indicate that although there have been preventive measures through the application of information technology, there are still loopholes that can be exploited by perpetrators of corruption. The main causal factors include the lack of legal awareness among the community, as well as minimal supervision and transparency in the use of the budget. This study recommends the need for increased training for law enforcement officers, as well as the implementation of a stricter and more transparent supervision system in the use of digital technology. Thus, this study is expected to provide valuable insights for policy makers in formulating more effective strategies to prevent and eradicate corruption, as well as increasing legal awareness among the Bandar Lampung community in this digital era.

Abstract

This study aims to explain the urgency of instilling character values in education in the modern era, describe the strategies or approaches used in the educational environment, and identify challenges and solutions in their implementation. The method used is qualitative with a descriptive approach. Data collection techniques included observation, in-depth interviews, and documentation, with the research subjects consisting of teachers, students, and principals at primary and secondary education levels. The results show that the cultivation of character values such as honesty, responsibility, discipline, tolerance, and cooperation is very important to form learners who not only excel in academics, but also have moral integrity and emotional maturity. Strategies used in character cultivation include integration of character values in learning, habituation of positive attitudes, teacher role models, and extracurricular activities. The main challenges in implementing character education are the negative influence of digital media, the weak role of the family, and the lack of consistency in character development. Solutions include improving educators' competence in character education, strengthening cooperation between schools and parents, and creating a school environment that supports a positive culture. Thus, character education should be an integral part of the education system, through synergistic cooperation between schools, families and communities.

Abstract

Adanya pasar di sekitar kawasan pemukiman masyarakat Kelurahan Tuah Karya mengakibatkan air permukaan bawah tanah menjadi tercemar. Penelitian ini bertujuan untuk menganalisa kedalaman air tanah dan kualitas air bawah tanah. Pengukuran menggunakan metode geolistrik konfigurasi Schlumberger pada 2 lintasan dengan panjang masing-masing 100 meter. Data yang diperoleh pada proses akusisi digunakan untuk menghitung nilai resistivitas semu pada titik pengukuran dan dianalisis secara kuantitatif dan kualitatif. Proses dilanjutkan dengan inversi menggunakan IPI2win sehingga didapatkan nilai resistivitas dan ketebalan lapisan pada setiap titik pengukuran. Berdasarkan hasil pengolahan data, lintasan pertama mendapatkan rentang nilai resistivitas berkisar 534,6 Ωm ­– 17.035 Ωm dan lintasan kedua berkisar 199 Ωm – 5254 Ωm. Sampel air bawah tanah diuji dengan parameter seperti pH, TDS, Konduktivitas, dan Kekeruhan. Air bawah tanah belum layak dikonsumsi dari hasil uji kualitas air dengan parameter-parameter yang telah disebutka sebelumnya jika merujuk pada Peraturan Menteri Kesehatan Republik Indonesia dikarenakan nilai konduktivitas yang melebihi standar baku mutu dan pH yang didapat pada semua sampel air bawah tanah bernilai <6,5 atau bersifat asam. Sementara untuk parameter TDS dan Kekeruhan memiliki nilai sesuai dengan standar baku mutu.

Abstract

Rooftop photovoltaic (RPV) systems are becoming increasingly popular as a source of renewable energy. One key factor that significantly affects the performance of RPV systems is the tilt angle of the solar panels. This study aims to determine the optimal tilt angle to maximize electricity production for the RPV system installed on academic building, Department of Electrical Engineering, Faculty of Engineering, University of Riau. The research method used is the PVSyst simulation. The simulation data input was used as daily weather for one year. In this study, variations in roof tilt angles of 5°, 10°, 15°, 20°, and 25° were examined. The results show that the optimal tilt angles for this location are 5° and 10°. At a 5° tilt angle, the RPV can generate 247,128 kWh per year with a performance ratio (PR) of 83%. And then at a 10° tilt angle, the system can generate 248,012 kWh per year with a PR of 82%. Based on the simulation results, other tilt angles also produced higher energy outputs but yielded lower PR values. This study provides practical recommendations for designing RPV systems in regions with similar weather conditions.
