Plastic waste, particularly plastic bottles, has become one of the major challenges in urban environmental management due to its increasing volume and potential to pollute ecosystems. In Bogor City, plastic waste constitutes a significant proportion of daily municipal solid waste, highlighting the need for effective and sustainable waste management models. This study aims to analyze the role of the Reduce, Reuse, Recycle Waste Processing Facility (TPS3R) in managing plastic bottle waste in Bogor City, with a case study of the Eco Techno Park at Ibn Khaldun University (UIKA) Bogor. The research employed a descriptive qualitative method using a case study approach. Data were collected through field observations, in-depth interviews with facility managers, and reviews of relevant documents and literature. The findings indicate that the TPS3R Eco Techno Park has successfully implemented the 3R principles through an integrated system supported by environmentally friendly technologies and a circular economy framework. Plastic bottle waste is managed through sorting, shredding, and recycling processes to produce value-added products, including plastic pellets, handicrafts, and construction materials. In addition, organic waste management is integrated through the cultivation of Black Soldier Fly (BSF) larvae. The facility has contributed to reducing the volume of waste sent to landfills by approximately 18%. The study implies that strengthening regulatory support, enhancing community participation, and developing circular economy-based business models are essential to ensure the long-term sustainability of waste management programs and support Bogor City's waste reduction targets.

TPS 3R is a community-based waste management approach aimed at reducing waste generation through reduce, reuse, and recycle activities. However, the operational sustainability of TPS 3R still faces several challenges,including  waste processing effectiveness, and community participation. This study aims to analyze the community’s Willingness to Pay (WTP) for waste management fees and to formulate priority recommendations for improving the performance of TPS 3R Banjar Sugihan using the Quality Function Deployment (QFD) method. The research was conducted in Banjar Sugihan Village, Tandes District, Surabaya City, involving 563 household respondents. WTP analysis was carried out using the bidding game method, while QFD analysis was conducted through the preparation of the House of Quality (HoQ). The results showed that the community’s WTP ranged from IDR 16,000 to IDR 19,000 per month. If applied to all 3,758 households in Banjar Sugihan Village, the potential retribution revenue is estimated to reach IDR 60,128,000–IDR 71,402,000 per month. The QFD analysis indicated that the priority strategies for improving TPS 3R performance include enhancing infrastructure facilities, optimizing waste sorting and processing, increasing waste processing capacity, strengthening human resource capacity, and implementing a WTP-based retribution system. Therefore, the implementation of a WTP-based retribution system and priority strategies derived from QFD analysis are expected to support the sustainability of waste management at TPS 3R Banjar Sugihan.

Waste is an environmental problem that can cause air pollution and health problems if not managed properly. The presence of Temporary Waste Disposal Sites (TPS) close to residential areas often produces unpleasant odors due to the decomposition of organic waste, thus disturbing the comfort of the community. This study aims to determine the relationship between the distance of homes from TPS and odor disturbances in the community in Andounuhu Village, Kendari City. The study used a quantitative method with a cross-sectional design on 58 respondents selected by purposive sampling. Data collection was carried out through questionnaires and observations, then analyzed univariately and bivariately. The results showed that residents living less than 100 meters from the TPS experienced odor disturbances more often than those living further away. The further the distance of the house from the TPS, the level of odor disturbance tended to decrease. This study shows that the proximity of residential areas to TPS affects environmental comfort, so that more optimal TPS management is needed through routine waste transportation and arranging TPS locations that are not too close to residential areas.

To support the planned development of a 3R Waste Management Site (TPS 3R) in 2026, a community service activity was conducted aimed at increasing community knowledge, awareness, and readiness regarding waste sorting and the application of the Reduce, Reuse, and Recycle concept. This activity used a participatory approach through outreach, waste sorting demonstrations, installation of educational boards on waste decomposition times, and the provision of separate trash bins in four hamlets. The results of the activity showed an increase in community understanding of waste types, 3R principles, and long-term environmental impacts, accompanied by positive responses and high enthusiasm. The educational boards and facilities provided served as visual reminders that encouraged behavioral change, making this activity an important first step in preparing the Gondang Village community towards sustainable waste management through the 3R Waste Management Site (TPS 3R).

This study is based on the suboptimal management of waste transportation in Tanjungpinang City, caused by limited fleet capacity, uneven service routes, a lack of human resources, and inconsistent implementation of Standard Operating Procedures (SOPs). This situation has led to waste accumulation at various points and an excessive load on the Ganet Final Disposal Site (TPA), which uses a controlled landfill system. The system aims to minimize pollution through waste compaction, soil covering, and leachate and methane gas management, but its implementation has not been optimal due to limited facilities and infrastructure. This study aims to evaluate the management of waste transportation to the Ganet landfill and identify the obstacles that arise. The approach used is descriptive qualitative with observation techniques, in-depth interviews, and document analysis, involving the Environmental Agency, the Ganet Landfill Technical Implementation Unit, field officers, fleet drivers, and residents around the Temporary Cleaning Site (TPS). The findings reveal that waste transportation management is already being carried out through standard operating procedures (SOPs) and inter-unit coordination, but is still hampered by fleet limitations, landfill capacity that is nearly full, service routes that do not cover the entire area, and minimal community participation. Therefore, additional fleets, infrastructure improvements, strengthened supervision, and community outreach are needed to achieve sustainable waste management.

The problem of illegal temporary shelters (TPS) is one of the serious environmental issues in Jambi City. Danau Sipin District is the district with the highest number of illegal TPS in Jambi City, namely 13 points. This study aims to determine the performance of the Environmental Management, Supervision and Enforcement Division (P3HL) the Jambi City Environmental Service the productivity aspect of the problem of illegal TPS in Danau Sipin District using the theory of public organization performance by Agus Dwiyanto (2006) with primary focus on productivity indicators. This can be seen from the utilization of various inputs such as human resources consisting of 3 field officers, operational facilities in the form of 1 patrol car, Standard Operating Procedures (SOP) for supervision, as well as clear and easy public reporting mechanisms to produce various outputs in the form of field supervision activities, enforcement of regulations, education and socialization to the public, and follow-up public reports. Although these various activities have been carried out, the limited number of field officers and operational facilities has resulted in the intensity of supervision in the field not being able to be carried out optimally. The conclusion of this study shows that the performance the Environmental Arrangement, Supervision and Law Enforcement Division of the Jambi City Environmental Service in terms of productivity has been running well, but still requires improvement, especially in the addition of human resources and operational facilities so that supervision and enforcement of regulations against illegal TPS can be carried out more optimally.

This study discusses the implementation of the Think Pair Share (TPS) strategy in Islamic Religious Education (PAI) learning in Grade VII of MTs Cerdas Murni, with a focus on its definition, steps, and advantages and disadvantages. This study uses a qualitative method with a phenomenological approach. The data used consist of primary data obtained through interviews and direct observation, as well as secondary data from books and journals. Data collection techniques include observation, interviews, and documentation, while data analysis is carried out through data reduction, data presentation, and verification. Data validity is tested using lingering techniques, triangulation, and negative cases. The results show that TPS is an effective cooperative learning strategy to increase student interaction and engagement. The steps in TPS include the stages of think, pair, and share. The advantage of this strategy is that it increases overall student participation, because each student is actively involved. However, the disadvantage is that it requires a relatively longer time to implement. Teachers have implemented TPS effectively, from greetings and prayers to build morals, to explaining prayer etiquette and dhikr, which enhance students' understanding, cooperation, and courage. TPS is suitable for material that requires in-depth understanding but needs to be adapted to the students' circumstances, such as using mixed methods for practical materials. Another advantage is increased student courage and critical thinking, despite challenges related to student readiness and facilities.

The waste problem in Karanglewas Village, Kutasari District, Purbalingga Regency, continues to increase alongside agricultural, trade, and MSME activities, while the management system remains conventional, without sorting, resulting in environmental pollution and limited landfill capacity. This community service program aims to implement the Integrated Independent Waste Sorting and Processing Tool (PLASMA-T) as an innovative solution that processes organic waste into compost and melts plastic waste into paving blocks that are useful and economical. The activities are carried out in stages, including problem identification, socialization, technical training, operational trials, evaluation of results, and the handover of the equipment to the Mitra Sejahtera TPS, with ongoing assistance so that the community can operate the equipment independently. The expected outcomes include a reduction in waste volume at the TPS, increased community awareness and skills in waste management, and the creation of new business opportunities through compost and paving block products. Thus, this program not only addresses environmental issues but also strengthens the village's circular economy and has the potential to serve as a model for other regions.

Increased production in the lubricant industry has become a significant issue because it generates production waste in the form of packaging, plastic, and paper waste as a direct consequence of manufacturing activities. Proper and systematic waste management is essential to reduce environmental impacts, comply with regulations, and support responsible and sustainable business practices. Lubricant production waste can damage the ecosystem and surrounding environment if not managed properly, so continuous innovation is needed to minimize environmental risks and reduce potential economic losses for the company. This study aims to analyze and implement effective waste management strategies using a combination of qualitative and quantitative approaches, including in-depth interviews with relevant stakeholders and analysis of secondary data obtained from company records. The waste management process begins with several waste reduction programs applied during the production stage to limit waste generation. Furthermore, the waste storage facility (TPS) available on the company’s premises, covering an area of 59 m², is capable of accommodating approximately 60% of the total waste that must be processed internally before further treatment or disposal.

This study aims to analyze the application of Think-Pair-Share (TPS) and Group Investigation (GI) cooperative learning strategies as pedagogical innovations in strengthening Islamic values and student learning independence in Islamic Religious Education (IRE) subjects. This study uses a library research method by examining various relevant scientific sources, including cooperative learning theory, the concept of independent learning, and Islamic educational values. The results of the study show that the integration of TPS and GI strategies can create an active, participatory, collaborative, and reflective learning process. Through paired discussions and investigative group work, students are trained to think critically, be responsible, and be able to work together harmoniously. In addition to improving academic understanding, the application of these two strategies also contributes to instilling Islamic values such as ukhuwah (brotherhood), amanah (trustworthiness), and mutual respect. Thus, this learning innovation is not only oriented towards cognitive aspects, but also towards character building and spirituality of students. The findings of this study are expected to be a reference for PAI teachers in developing effective, contextual, and Islamic character learning strategies.

In the era of globalization and digital transformation, organizations strive to maintain competitiveness through optimizing internal factors such as work culture, business process engineering (BPR), and decision support systems (DSS). This qualitative research based on a Systematic Literature Review (SLR) analyzes the relationship between these three using the Denison Organizational Culture Model, Hammer & Champy BPR, and the Resource-Based View (RBV). It finds that work culture mediates the implementation of BPR and DSS to increase efficiency by 30-50%, employee productivity, and sustainable competitive advantage. Case studies such as the Toyota Production System (TPS) confirm this synergy, resulting in reduced costs, cycle times, and improved service quality. This research also emphasizes the importance of a strong work culture in supporting the implementation of new technologies and methodologies, which in turn strengthens the company's market position. Thus, organizations that are able to integrate these three elements will be better prepared to face the challenges of globalization and dynamic changes in their industry, creating a sustainable advantage and being able to survive in a highly competitive market.

Organic waste management at Yogyakarta International Airport (YIA) is still not optimal, even though organic waste production averages 1,264 kg per month. This community service activity aims to develop technological innovations through the utilization of eggshell waste and Black Soldier Fly (BSF) maggots into economically valuable pellet feed products. The activity was carried out from October 8 to 15, 2025, involving three workers from the Temporary Processing Site (TPS) of PT Angkasa Pura Indonesia YIA. The implementation methods included an initial survey, education, demonstration of pellet production, and evaluation of participants' skills and product quality. The production process involved drying, grinding the ingredients, mixing the ingredients, molding, and drying the pellets. The results showed that the workers were able to independently carry out the production process and produce pellets with good physical quality. Cost analysis showed that the cost of production was IDR 47,989/kg, with a potential profit margin of 30% and an estimated return on investment within ±7 months. This innovation has proven effective in reducing waste volume, increasing the added value of organic waste, and supporting the principles of zero waste and circular economy in the airport area. This program has the potential to be further developed as a model for sustainable organic waste management.
