Pembangunan berkelanjutan menuntut pengelolaan sumber daya yang efisien dan ramah lingkungan. Penelitian ini mengkaji integrasi tiga sistem utama: pembangkit listrik tenaga mikro hidro (PLTMH), sistem plumbing hemat air, dan alat pirolisis sampah rumah tangga. Ketiganya dianalisis melalui studi literatur dan perbandingan data dari tiga studi kasus di Indonesia. Hasil menunjukkan bahwa PLTMH di Dusun Batu Rangin mampu menghasilkan daya 48,56 kW dan mengurangi emisi CO? sebesar 156 ton/tahun. Sistem plumbing hemat air di Rusun Brimob Sampali menurunkan konsumsi air hingga 33,52% dan meningkatkan efisiensi daur ulang air hingga 87%. Sementara itu, pirolisis sampah rumah tangga menghasilkan bio-oil dengan nilai kalor tinggi dan menunjukkan potensi ekonomi dengan ROI 1,58. Integrasi ketiga sistem ini membentuk model pengelolaan sumber daya yang saling mendukung, dengan indeks keberlanjutan 3,7 dari 5. Pendekatan ini sejalan dengan konsep circular economy dan berpotensi diterapkan secara luas di wilayah pedesaan Indonesia.

This research focuses on developing a cayenne pepper quality detection system using the YOLO (You Only Look Once) V5 algorithm. The system is designed to address the limitations of manual post-harvest sorting by classifying cayenne peppers into three categories: “good” (ripe), “bad” (rotten or dry), and “raw” (green), based on their visual characteristics. A dataset consisting of 565 images was manually collected, labeled using Roboflow, and pre-processed through resizing and orientation standardization. Model training was conducted over 150 epochs, achieving high detection performance with a mean average precision (mAP) of 99.5%, precision of 99.6%, and recall of 99.9%. Real-time testing demonstrated the system’s capability to detect and classify cayenne peppers with exceptional accuracy. This research is expected to enhance the efficiency and accuracy of the cayenne pepper sorting process, while paving the way for the application of YOLO-based systems to other agricultural commodities. Further research is recommended to expand the dataset and optimize model parameters for improved system performance.

The decline in the marriage rate in Indonesia in the last decade is a complex phenomenon with many interrelated causes. The institution of marriage, once a strong tradition binding two individuals in a commitment to live together, has undergone significant changes in recent decades. The latest data from the Central Statistics Agency (BPS) shows a decreasing trend in the marriage rate nationally. In 2023, there will only be 1,577,255 marriages recorded in Indonesia, a decrease of 128,000 from the previous year. During the last decade, the marriage rate experienced a significant decline of 28.63 percent. In-depth research highlights the socio-economic factors, changes in mentality, and the influence of online mass media, especially social media, that play a role in this change. The influence of online mass media, particularly social media, is also a factor that cannot be ignored in understanding changing attitudes towards the institution of marriage. Social media has broadened access to information and facilitated communication between individuals in unprecedented ways. Not only does this change the way individuals interact and form relationships, but it also influences perceptions of traditional values such as marriage.

The life of the people of Jember, which has long been inseparable from tobacco farming activities, sparked the birth of the idea of building a tobacco museum. This tobacco museum can be said to be a representation of how tobacco developed in the city of Jember. Several aspects contained in it also support the representation process. Starting from the beginning of the construction of the museum which was inspired by the habits of the people of Jember city, namely tobacco farming, the names of several agricultural tools were born from the language of the local community, even to the concept of the building which was interpreted as having similarities with one of the tools for tobacco production, namely the Atag warehouse. This research uses a representation theory perspective proposed by Stuart Hall. According to Hall, there are three approaches to the representation process consisting of reflective, intentional and constructionist approaches. The aim of this research is to find out how the representation process occurs in the tobacco museum. This type of research is qualitative research with an ethnographic approach. The results of the research show that there has been representation in the tobacco museum where the process involves various aspects contained in the museum itself.
 
 

Seeing the important role of entrepreneurship in the Indonesian government's economy, universities in Indonesia have provided education on entrepreneurship for their students. It is intended that their students can become entrepreneurs after graduating from college. However, becoming an entrepreneur is not easy, because it requires strong motivation from within a person to start their own business. The decision to become an entrepreneur is also not popular because of the large responsibilities that must be borne by business owners. Therefore this study wants to see the meaning of entrepreneurship for an alumnus of Business Administration Education. This research was conducted using a qualitative phenomenological method. The results of this study state that several attitudes must be owned by an entrepreneur, challenges that must be faced by an entrepreneur, and the benefits of entrepreneurship. The subjects of this study were alumni of the Universitas Negeri Malang Faculty of Economics and Business Commerce Education who already have their businesses. This research is also expected to be able to provide additional contributions to material about entrepreneurship
