Household waste management remains a critical challenge in creating clean and sustainable residential environments. Manual monitoring methods often lead to delayed waste collection, overflowing bins, and operational inefficiency. This community engagement program implements an Internet of Things (IoT)-based Smart Trash Monitoring SIstem (STMS) at Graha Panyindangan Estate, Indramayu. The sIstem utilizes ultrasonic sensors and ESP32 microcontrollers to detect the fill level of household waste containers and transmit data in real time to a user-accessible dashboard. The results demonstrate that the STMS provides accurate waste-level information, reduces manual inspections, enhances collection efficiency, and fosters data-driven behavior among residents. Social changes also emerged, including improved environmental awareness, new social norms, and the emergence of local leaders supporting sIstem sustainability. This program contributes to the realization of smart living in modern residential communities, ensuring better waste management, cleaner environments, and more sustainable practices for future generations. It also provides valuable insights into the role of technology in addressing environmental issues at the community level.

The rapid pace of housing development in Bogor has created a gap with the provision of formal infrastructure, which has encouraged the emergence of community-led self-help road initiatives. While capable of addressing urgent connectivity needs, these road formations often ignore essential design standards, particularly those related to circulation and environmental context. This study focuses on a specific challenge in Bogor, namely high rainfall ("force of nature"), which contributes to road degradation, causing flooding, and reducing user comfort. Adopting a descriptive qualitative method, this study analyzes the existing self-help access conditions through field observations and a literature review focusing on Water Sensitive Urban Design (WSUD) principles and circulation theory. Field findings confirm that the current design fails to manage surface runoff, resulting in low infiltration and the emergence of functional space conflicts (e.g., for parking and social activities). As a solution, this study proposes an integrated design demonstration that combines porous materials and micro-drainage to manage the force of nature, thereby improving circulation comfort and supporting active living for residents.

This study aims to analyze the effectiveness of the implementation of the subsidized housing program for low-income communities in Pekanbaru City. The background of this research stems from the high demand for decent housing among low-income groups and the government’s challenge in ensuring equitable access to affordable housing. The research method employed is descriptive qualitative with a policy study approach. Data were collected through in-depth interviews with officials from the Department of Public Housing and Settlement Areas, housing developers, banking institutions, and program beneficiaries. Field observations and documentation were also conducted to strengthen data validity. The results show that the implementation of the subsidized housing program in Pekanbaru City has been in line with national policies, yet its effectiveness remains suboptimal. This condition is influenced by insufficient policy dissemination, limited strategic land availability, inaccurate targeting of beneficiaries, and weak supervision mechanisms. On the other hand, supporting factors such as regulatory support, partnerships with the private sector, and accessible financing through subsidized home ownership loans have contributed to the program’s success. In conclusion, the effectiveness of program implementation can be improved through stronger inter-agency synergy, transparency of beneficiary data, and institutional capacity building so that the goal of equitable access to decent housing for low-income communities can be sustainably achieved.

This study aims to determine the effect of training and work motivation on the performance of employees at the Jambi Province Public Works and Public Housing Agency. The background of this research is the decline in employee performance target achievements, which is influenced by budget constraints, limited training opportunities, and low work motivation due to a lack of recognition and organizational support. The research method used is a quantitative method with a descriptive approach and a case study, conducted on employees of the Public Works and Public Housing Agency of Jambi Province. The results show that training has a positive and significant effect on improving employee performance. Training not only serves as a means of instruction but also as a tool for developing employee skills and competencies. Conversely, work motivation has a negative and insignificant effect on employee performance, which is influenced by unmet needs for security, recognition, and encouragement to achieve goals. However, simultaneously, training and work motivation have a positive and significant effect on employee performance. This study concludes that effective training management and appropriate motivational strategies are crucial for improving the performance of employees at the Public Works and Public Housing Agency of Jambi Province.

Cases of non-performance of contract. on the part of the aggrieved party bring the case to the criminal realm. The charge reported is the fraud article, even though the criminal offense has not been fulfilled. So that it has the potential to cause wrong criminalization, the main problem is the inaccurate use of the fraud article against defaults which are basically civil. The research method uses normative juridical with decision analysis and criminal and civil law studies related to non-performance of contract. and fraud. The results show that non-performance of contract. can only turn into a criminal offense of fraud if there are elements of intent, bad faith, use of deception, or falsification of agreements with the intention of benefiting oneself against the law. Therefore, law enforcement officials should be careful in distinguishing non-performance of contract. and fraud cases to avoid abuse of the law that harms the parties concerned. The hopes and solutions proposed are proportional law enforcement by paying attention to the element of malicious intent in determining criminal offenses, as well as legal education to the public so that they understand the difference between the civil and criminal domains in contractual disputes.

Low-Income Communities (MBR) often live in Uninhabitable Houses (RTLH) due to financial constraints, which hinder their ability to improve their welfare and meet their basic living needs. The government is responsible for fulfilling the need for Decent Housing (RLH) for the community, which is realized through the Stimulant Assistance for Self-Help Housing (BSPS) program. The BSPS program aims to improve the quality of housing for the community through financial assistance and empowerment. This research was conducted in Belawan Bahari Village, Medan Belawan District, Medan City, which is a coastal area prone to tidal flooding. The main informants in this study were the Chairpersons of Assistance Recipient Groups I and II of the BSPS Program. Additional informants included the Head of Neighborhood Unit XII in Belawan Bahari Village. Key informants consisted of the Commitment Making Officer for Self-Help Housing and RUK, as well as Technical Experts from BSPS who are responsible for the activities and implementation of the BSPS program in Belawan Bahari. Data collection techniques were carried out through literature studies and field studies, including observation, interviews, and documentation. The data obtained in the field were then analyzed qualitatively by the researcher to draw conclusions from the research findings. The results indicated that the BSPS program in Belawan Bahari Village was effective in providing decent housing for aid recipients. This effectiveness was assessed based on program effectiveness indicators determined by Sutrisno, demonstrating success in terms of program understanding, targeting accuracy, timeliness of implementation, achievement of objectives, and tangible changes for aid recipients. Decent housing was evaluated based on building durability, adequacy of living space, access to safe drinking water, proper sanitation, as well as lighting and ventilation.

Housing, as a basic human necessity, demands not only physical comfort but also assurance of safety and legal protection for its residents. In recent years, the rise in security violations within residential areas has raised serious concerns, especially regarding the authority of housing management and the frequent neglect of residents’ rights. Various security policies such as 24-hour gate security, CCTV installation, and visitor access restrictions are often enforced without a clear legal basis and without the participation of residents, thereby creating the potential for legal violations, including those related to criminal law and human rights. This study aims to analyze the forms of criminal liability that may be imposed on housing management in cases of negligence or abuse of authority in the implementation of security policies. It also examines the forms of legal protection available to residents and identifies potential criminal law violations arising from such policies. The research adopts a normative and empirical juridical approach, with a case study conducted at DL Sitorus I Housing Complex in Simalungun Regency. The results of the study show that the security policies at DL Sitorus I lack a valid internal legal foundation, were not developed through participatory means, and are not supported by standardized operating procedures (SOPs). This situation creates room for overreach by security personnel, such as arbitrary detention of visitors and unauthorized interrogations, which may violate Article 333 of the Indonesian Penal Code. Management may be held indirectly criminally liable under the principles of culpa in vigilando (negligence in supervision) and culpa in eligendo (negligence in the selection of personnel). The study recommends the formulation of internal regulations based on resident participation and the provision of legal training for security officers to ensure a fair, transparent, and legally compliant residential security system that upholds the principles of criminal law and human rights protection.

The Waste Bank is an initiative born out of public concern for the environment, particularly in addressing the growing waste problem. The problem faced by the Seruni Waste Bank Association is that the management of waste deposit data is still carried out using conventional bookkeeping, which often results in errors in recording the nominal amount of waste deposits. This error results in losses for the Waste Bank Association and a lack of transparency between officers and members and customers. The purpose of this study is to help create a waste bank management system so as to reduce losses for the association. The research methodology employed is the waterfall methodology, which involves a research design comprising needs analysis, system design, implementation or coding, program testing and evaluation, and maintenance. The definition of users obtained from the results of observations and interviews resulted in two levels of users: owner and junior. System testing includes blackbox testing with test cases that are all accepted or valid, and user acceptant testing with results that are strongly agreed to be accepted by the association. This system has proven effective in helping officers manage waste bank data, especially in reporting waste deposit transactions, thereby improving the performance and transparency of Seruni waste bank operations.

This study aims to examine the use of amortization schedules and the repayment fund approach in Public Housing Credit. By applying quantitative descriptive methods and a case study approach, this study simulates a mortgage with a credit ceiling of Rp163,800,000, a tenor of 15 years, and an interest rate of 5.65% for the first to fifth year and 13% for the sixth to fifteenth year. The results of the simulation show that without any additional strategies, the total interest to be paid reaches Rp138,887,134.14, which is almost equivalent to the total principal loan. However, by using a sinking fund strategy through regular savings of Rp1,000,000 every month (with an interest rate of 0.25% per month) for 5 years, the collected funds are Rp64,444,800 which significantly reduces the remaining principal loan. As a result, the total interest is reduced to Rp87,864,324.85, which means there is a savings of Rp51. 022. 809.29. Furthermore, this strategy has the potential to shorten repayment time. In conclusion, sinking funds are an effective approach to reducing interest burden and accelerating the repayment of Public Housing Loans.

This study aims to analyze how internal strategies and external challenges can influence the achievement of Regional Original Revenue targets at the Laboratory Technical Implementation Unit (UPTD) of the Public Works and Public Housing Agency (Dinas Pekerjaan Umum dan Perumahan Rakyat) of Cilacap Regency. The research object is the performance of the Laboratory Technical Implementation Unit (UPTD), a technical unit providing construction material testing services, which directly contributes to Regional Original Revenue in Cilacap Regency. The qualitative approach employed a case study method, and data collection techniques included interviews, observation, and documentation. The sample in this study was obtained purposively. The results indicate that internal strategies focused on superior testing methods such as core drilling, abrasion, and concrete compressive strength have been conducted. However, limited equipment, human resources, and the lack of accreditation are major obstacles. On the other hand, external challenges include the lack of updated Regional Regulation tariff regulations, the absence of formal obligations for the use of laboratory services for regional budget projects, and a saturated local market. These findings provide important implications for the Laboratory Technical Implementation Unit (UPTD) in emphasizing policy revisions, increasing internal capacity, and strengthening inter-agency coordination to increase Regional Original Revenue realization.

The design of Lecturer Housing for Campus 4 Gorontalo State University is a strategic necessity in line with the expansion of educational institutions and the increasing number of educators requiring adequate and proximate housing. The primary objective of this research is to produce a lecturer housing design that is not only adaptive and sustainable, but also harmonized with the Regional Spatial Plan (RTRW) of Bone Bolango Regency. The research methodology encompasses a comprehensive site analysis, examining aspects such as climate conditions, topography, vegetation patterns, infrastructure and utility networks, ambient noise levels, and site accessibility. Furthermore, a zoning and spatial relationship study was conducted to determine effective space allocation based on the principles of tropical architecture and green building practices. The findings of the study highlight that a north-south building orientation significantly reduces heat absorption, while the integration of cross-ventilation strategies enhances natural airflow and thermal comfort. Spatial zoning into public, semi-public, private, and service areas allows for organized layouts and promotes social interaction among residents. Sustainability is reinforced through the application of green architectural technologies, including the use of green concrete, lightweight steel frameworks, solar energy panels, as well as integrated waste-water management systems that separate black water and grey water. Landscaping elements, both softscape and hardscape, are utilized to enhance aesthetics while supporting ecological balance and rainwater absorption. This design proposal contributes to the broader discourse of sustainable tropical housing and may serve as a replicable model for future lecturer housing projects in similar regional contexts. It emphasizes the importance of environmentally responsive, cost-efficient, and socially supportive residential architecture.

A qualitative descriptive method was employed, utilizing field observation, in-depth interviews with local residents and traditional leaders, and documentation of existing conditions. The findings indicate that basic infrastructure components such as neighborhood roads, clean water supply, sanitation systems, drainage, and waste management are in inadequate condition. Therefore, the study recommends an integrated planning approach for infrastructure improvement, emphasizing active community participation in the management and maintenance of the residential environment to achieve a habitable and sustainable settlement.

This study aims to analyze the effect of company size, profitability, investment, and free cash flow on dividend payment policy in manufacturing companies listed on the Indonesia Stock Exchange (IDX) for the 2019–2021 period. The research method used is a quantitative approach with multiple linear regression analysis techniques. The sample in this study consisted of 25 manufacturing companies selected through a purposive sampling method based on certain criteria. The results of the study indicate that company size, investment, and free cash flow have a positive and significant effect on dividend payment policy. Meanwhile, profitability has a negative and significant effect on dividend payment policy. This finding indicates that dividend payment policy is more influenced by the financial and liquidity aspects of the company, not solely by the level of profitability. This study implies that companies need to consider internal factors such as size and cash flow in formulating dividend policies, especially in uncertain economic conditions.

The objective of this study is to evaluate the financial performance of PT PP (Persero) Tbk over the period from 2020 to 2023. The assessment was conducted by analyzing several key financial ratios, including profitability, liquidity, solvency, and activity ratios. This study employed a descriptive quantitative approach using secondary data obtained from the company’s annual financial statements. The analysis revealed a decline in the company’s profitability, as indicated by a downward trend in the Return on Assets (ROA) and Return on Equity (ROE) ratios. The company's liquidity remained relatively stable but was still below the ideal standard, particularly in the quick ratio, indicating a need for improvement in the management of liquid assets. The solvency analysis revealed a high dependency on debt, which could increase financial risk if not properly managed. Meanwhile, the activity ratios showed a decrease in operational efficiency in utilizing assets to generate revenue. These findings support the hypothesis that PT PP (Persero) Tbk is facing challenges in maintaining financial health, particularly in balancing growth with sustainable performance. This study has limitations, including a data scope restricted to financial ratios and the absence of consideration for external factors such as macroeconomic conditions and industry comparisons. Future research is recommended to adopt a more comprehensive and integrative approach by combining quantitative and qualitative methods, in order to gain deeper insights into financial decision-making processes and the company’s strategic direction.  

The implementation of coal mining activities with an open pit system at the end of its activities will leave behind the remains of former mining holes. Control of acid mine water is something that needs to be done during mining activities until the end of the mining process because acid mine water can cause a decrease in the quality of surface water and groundwater and have an impact on the survival of humans and biota that live on land and water. The initial characteristics of water using the floating treatment method of wetland, the pH, TSS, Fe, and Mn values ​​of ex-mining lake water do not meet the quality standards of the Government Regulation of the Republic of Indonesia Number 22 of 2021. The ability of water hyacinth plants to increase pH for 25 days is quite good with an initial pH value of 4.13 to 7.34. For 25 days, the TSS parameter of water hyacinth plants is also good at reducing TSS levels with an initial value of 6 mg/L to 3 mg/L, the Fe parameter of water hyacinth plants is also good at reducing iron levels with an initial value of 1.06 mg/L to 0.34 mg/L, while the Mn parameter of water hyacinth plants is quite good at reducing manganese levels with an initial value of 1.13 mg/L to 0.32 mg/L.
