This research aims to develop a transaction data security system on the web-based Pancadaya Waste Bank application by applying a hybrid cryptographic algorithm that combines Advanced Encryption Standard (AES) and Rivest Shamir Adleman (RSA). The problem faced in the previous system is the weak recording and security of customer transaction data, because the process is still carried out manually so that it is prone to recording errors, loss of important information, and potential misuse of data by unauthorized parties. To answer these problems, this study uses the Rapid Application Development (RAD) method which allows the application development process to be carried out quickly, flexibly, structured, and according to user needs. The research method used was a qualitative approach with interview techniques with the management of the Pancadaya Waste Bank and the Environment Office, as well as an in-depth literature study on the application of hybrid cryptographic algorithms in modern information systems. The system is built using the PHP programming language, MySQL database, and OpenSSL library as the main support for the data encryption and decryption process. The implementation of the algorithm is carried out by encrypting transaction data using AES for efficiency and speed, then the AES key is secured through RSA to ensure a higher level of security while preventing illegal access. The test results showed that the system was able to encrypt and decrypt transaction data in real-time, as well as display transaction results in the form of digital notes on deposit and balance withdrawal activities. In addition, performance tests using GTmetrix showed that the application has excellent speed, stability, and processing efficiency, making it feasible to be widely implemented in Pancadaya Waste Bank operations.

This study was conducted to analyze the influence of motivation, work discipline, and work ability on service quality at the Village-Owned Enterprise (BUMDes) in Kedungudi Village, Trawas District, Mojokerto Regency. The background of the study stems from the important role of human resources in supporting the quality of public services, especially in the Waste Bank business unit managed by the BUMDes. Human resources are considered the most strategic asset in achieving organizational goals, especially in community-based enterprises such as village-owned enterprises. The study used a quantitative approach with a survey method. The research sample was all 25 BUMDes employees and was determined using a saturated sampling technique. The research instrument was a questionnaire with a Likert scale that had undergone validity and reliability tests. The use of a Likert scale questionnaire ensures measurable perceptions and attitudes from respondents regarding the studied variables. Data analysis was conducted through multiple linear regression with the assistance of SPSS software. The results showed that partially, work discipline and work ability had a significant positive effect on service quality, while motivation had a significant negative effect. This finding indicates that motivation, if not aligned with organizational needs, may lead to counterproductive outcomes. Simultaneous testing showed that all three variables significantly influenced service quality, with a coefficient of determination of 68.8%. In other words, nearly 70 percent of service quality can be explained by motivation, work discipline, and work ability. This finding underscores the importance of holistic human resource management, encompassing strengthening work discipline, improving competency, and reviewing the motivation system to align with both organizational and individual needs. Research recommendations include evaluating the motivational models used, consistently monitoring discipline, and providing ongoing training. Continuous training and development programs are essential to sustaining and improving service quality in the Kedungudi Village-Owned Enterprise (BUMDes).  

The Community Service Program (KKN) is an intracurricular activity that is mandatory for students as a form of community service. In this context, the KKN group R1 of Janabadra University Yogyakarta conducted a service activity in Banyurejo Village, Yogyakarta City, for six weeks. This activity carried the main theme of community empowerment in environmental management, with a primary focus on increasing awareness of the economic potential of waste through the implementation of an Environmental Workshop with the theme "Waste as Economic Potential: Creating an Independent and Clean Village." This workshop was the core agenda that involved the active participation of residents in discussing and practicing waste management that was wise, economically valuable, and environmentally friendly. To support this main activity, several supporting programs were also implemented, including: Ceria Class as a medium for environmental education for children, the establishment of a Waste Bank, joint exercise activities with residents, village clean-up actions, synergy with the PKK women's group, and educational seminars on the environment and health. All activities were designed with a community-based educational and participatory approach, to encourage direct community involvement in creating change. During the implementation period, this program showed positive results. There was an increase in public awareness of the importance of structured and sustainable waste management. Furthermore, residents have begun to demonstrate their initiative by establishing neighborhood-level waste banks, demonstrating their commitment to community-based waste management. Participation from various community elements, including children, housewives, and community leaders, is key to the success of this initiative. The success of the Janabadra University Community Service Program (KKN) group R1 is expected to serve as a model for other regions in designing and implementing community empowerment programs, particularly in the environmental sector.

The problem of waste management in Indonesia is increasingly pressing, with more than 11.3 million tons of waste unmanaged each year. Semarang City, which produces 1,300 tons of waste per day, faces similar challenges with suboptimal waste collection rates. In response to this crisis, the Semarang City Government launched the “Clean Semarang” program with a zero waste approach by strengthening more than 150 community-based waste banks. This study uses a qualitative case study approach to analyze the implementation of the program, the role of waste banks, management challenges, and their contribution to SDGs 11.6 and 12.5. The results show that waste banks play a role in environmental education, reducing waste to landfills, economic empowerment, and cross-sector collaboration. However, unequal community participation, limited infrastructure, and policy barriers remain challenges. This program has proven to be relevant in encouraging sustainable waste management and can be a model for replication in other cities.

Community-based waste management is a strategic step toward achieving sustainable development in Gresik Regency, Indonesia. This policy aims to reduce waste volume, raise community awareness, and support the vision of a Green Regency. This study evaluates the implementation and effectiveness of community-based waste management policies using a qualitative case study approach. Data were collected through in-depth interviews, participatory observation, and document analysis, then analyzed thematically to identify supporting and hindering factors influencing program success. The findings indicate that while progress has been made, significant challenges remain, including low levels of socialization, limited infrastructure, and weak inter-agency coordination. Community participation depends heavily on local leaders and facilitators, and the sustainability of institutions such as waste banks and management groups has yet to be evenly distributed. Adequate infrastructure, such as integrated waste processing facilities (TPS3R), is crucial and needs enhancement. Barriers like a lack of technical experts, cultural habits of indiscriminate waste disposal, and insufficient funding hinder the achievement of policy objectives. This evaluation underscores the necessity for increased education, institutional strengthening, and improved infrastructure to accelerate behavioral change and boost community participation. The results are expected to inform local government strategies for more effective implementation toward realizing a sustainable and environmentally friendly Gresik. An integrated and holistic approach is essential for optimizing waste management, creating a cleaner, healthier, and sustainable environment.

This study aims to find out the collaboration of actors in waste management in landfills (TPA). This study uses descriptive research using qualitative research methods and using Ratner's (2012) theory which includes Identification of Barriers and Opportunities, Debate Strategies to Influence, and Collaborative Action Planning. There were 5 informants in this study. The results of the study show that the collaboration that occurs in waste management has gone well, but there are still obstacles in overcoming existing problems. To identify obstacles and opportunities, there are situations and needs as well as resources that must be met, the collaboration that occurs between the Environment and Hygiene Agency and the head of waste management and b3 waste has been running but is not optimal enough due to the lack of resources in facilitating infrastructure facilities at landfills. Debate strategies to influence and increase public awareness and understanding require socialization related to understanding how to manage waste properly. The Head of the Environment and Hygiene Agency together with the Head of the B3 Waste Management Division have collaborated with the Mutiara Timor Waste Bank in providing effective socialization to reduce the volume of existing waste, but many people do not understand the socialization. Planning this cooperation action, there is a collaborative implementation strategy where the actors collaborate in planning the right implementation strategy to reduce the volume of waste in the landfill, but the collaboration between the Head of the Environment and Hygiene Agency and the Mutiara Timor Waste Bank has targeted 20% in handling the volume of waste, but the cooperation is only 5% that can reduce the volume of waste in the landfill because the socialization provided is still not understood by the Public. For the purpose and purpose of this cooperation is the target in reducing and handling waste from 2018-2025, if this cooperation runs effectively and successfully, slowly the volume of waste in landfills will decrease by itself.

Timbulan sampah di Kabupaten Bone Bolango menunjukkan tren peningkatan yang signifikan dari tahun ke tahun, seiring dengan pertumbuhan jumlah penduduk, ekspansi kawasan permukiman, dan aktivitas ekonomi masyarakat. Berdasarkan data dari Sistem Informasi Pengelolaan Sampah Nasional (SIPSN), terjadi lonjakan volume sampah harian dari 2022 hingga 2024. Namun, peningkatan ini tidak diimbangi dengan kapasitas pengelolaan yang memadai, baik dari sisi infrastruktur, kelembagaan, maupun partisipasi masyarakat. Studi ini bertujuan untuk mengkaji model pengelolaan sampah berkelanjutan di Kabupaten Bone Bolango melalui pendekatan sistem, dengan merujuk pada literatur dan data sekunder. Metode analisis menggunakan pendekatan Causal Loop Diagram (CLD) dan Stock Flow Diagram (SFD) untuk mengidentifikasi hubungan kausal dan dinamika sistem pengelolaan sampah di daerah ini. Hasil kajian menunjukkan bahwa akar permasalahan terletak pada lemahnya sinergi antar-pemangku kepentingan, kurangnya regulasi lokal, serta keterbatasan sarana pengolahan. Solusi strategis yang diusulkan meliputi pembangunan fasilitas TPS3R, penyusunan kebijakan persampahan daerah, pemberdayaan masyarakat melalui edukasi lingkungan dan bank sampah, serta penguatan kemitraan dengan sektor swasta dan lembaga non-pemerintah. Diharapkan, pendekatan integratif ini dapat menjadi dasar bagi pengembangan model pengelolaan sampah yang efektif dan berkelanjutan di Kabupaten Bone Bolango.

The increase in consumption of plastic bottled drinking water (AMDK) has led to an increase in the amount of plastic waste that requires special handling. One of the main challenges in managing this waste is the process of cutting plastic cup rings, which has been done manually using a cutter or small knife. This manual method is not only less effective but also increases the risk of injury for waste pickers. This research aims to develop a safer and more effective plastic cup ring cutter. Through a socialisation programme and implementation of the tool at Bank Sampah SiHatin, the effectiveness of the tool was tested by comparing the manual method and the use of the cutting tool. The results of the analysis show that the use of this tool is able to increase the cutting speed by 58%, produce more uniform cuts, and eliminate the risk of injury due to the use of cutters. In addition, this tool also improves occupational safety and health (K3) aspects and has a positive impact on the economic value of cutting products. Thus, this innovation is an effective solution in plastic waste management in the informal sector and can be adopted more widely in various other Waste Banks
