  • Comparative Study of K-Means and Mean Shift Clustering Algorithms for Waste Data in West Java Province

    Authors: Rony Setyawan, Geraldi Catur Pamuji

    Abstract

    This study presents a comprehensive comparative analysis of the k-Means and Mean Shift clustering algorithms, utilizing waste data collected from West Java Province’s final disposal site spanning 2016 to 2021, with the primary objective of evaluating their performance and applicability for waste management practices; the analysis encompasses several critical parameters, including the number of clusters generated, variable uniformity, evaluation metrics employed, divergence measures, and processing time efficiency, revealing that k-Means, which formed three clusters, excels in rapid processing and provides finer cluster division, while Mean Shift, yielding two clusters, offers nuanced insights into data patterns, leading to the recommendation that the choice between the two algorithms should be driven by specific project requirements and considerations such as urgency of waste management needs and the depth of understanding desired for effective decision-making, thereby offering a tailored approach to waste data organization that optimizes categorization and contributes to more efficient and sustainable waste disposal practices in the future. © School of Engineering, Taylor’s University.

  • Chili Plant Monitoring System Using Yolo Object Detection Technology

    Chili Plant Monitoring System Using Yolo Object Detection Technology

    Authors: Harun Sujadi, Budiman B., Dony Susandi, Elba Ghiffari Fitriasina, Trustorini Handayani

    Abstract

    Traditional farming in chili cultivation often needs help in monitoring plant conditions efficiently. Farmers generally use manual methods to identify pests and determine soil nutrient requirements, which are often inaccurate and time-consuming. This study aimed to improve the efficiency and productivity of chili cultivation by implementing smart farming technology using the YOLO (You Only Look Once) algorithm for real-time leaf pest detection. The method used is system development, which includes data collection, model training, and system performance evaluation. The test results showed that YOLO technology can identify pests with reasonably high accuracy, allowing farmers to take quick and precise action. The implementation of smart farming is expected to increase productivity, reduce losses due to pests, and support sustainable agricultural practices. The main contribution of this study was the development of a YOLO-based monitoring system that can support the efficiency of chili farming in Indonesia. © School of Engineering, Taylor’s University.

    Abstract

    Agricultural production contributes significantly to greenhouse gas (GHG) emissions and global climate change. This study conducts a systematic literature review to examine the evolution and drivers of agricultural GHG emissions. We analyzed Web of Science, Scopus, and Google Scholar data using bibliometric and thematic methods. Our analysis identified emission sources such as energy use, soil management, fertilizer application, and livestock management. It also discussed mitigation measures such as sustainable practices, precision agriculture, and renewable energy. The findings showed that crop cultivation, livestock activities, and land-use change remained key sources of emissions. Technological innovations and policy-driven strategies are reshaping the research landscape. This study provides a framework for understanding agricultural GHG emissions and supporting interventions to reduce the sector’s carbon footprint as well as Sustainable Development Goals (SDGs). © 2025 Kantor Jurnal dan Publikasi UPI.

    Authors: Senny Luckardi; Agis Abhi Rafdhi; Annisa Wulan Sari; Hewa Majeed Zangana; Eddy Soeryato Soegoto

    DOI: 10.17509/ajse.v6i1.89992

    Abstract

    This study explores how to improve the productivity of hydroponic leafy vegetables by balancing Total Dissolved Solids (TDS) and nutrient solution pH. Using bok choy in a floating raft system, the research applies a controlled experimental design to observe how these parameters interact in supporting vegetative growth and yield. Daily monitoring and careful adjustment of nutrient levels and pH are emphasized to ensure optimal nutrient uptake. Balanced TDS and pH conditions enhanced leaf formation and biomass accumulation, while imbalances caused nutrient stress and growth inhibition. This study offers practical guidance for growers to synchronize TDS and pH in real-time for improved nutrient management. The findings contribute to precision hydroponics aligned with sustainable agriculture, specifically supporting sustainable development goals (SDGs) for SDG 2 (Zero Hunger) through efficient food production and SDG 12 (Responsible Consumption and Production) by encouraging optimal use of agricultural inputs. © 2026 Universitas Pendidikan Indonesia.

    Geographic Information System (GIS) Application to Identify the Distribution of Tourist Attractions and Supporting Facilities Related to the Sustainable Development Goals (SDGs)

    Authors: Lia Warlina, Afredi A.

    DOI: 10.17509/ijost.v11i2.89803

    Abstract

    The purpose of this research is to examine the distribution patterns of tourism attractions, hotels, and restaurants, and to explore their implications for achieving the Sustainable Development Goals (SDGs) in Lembang District. To analyze these distributions, a quantitative approach was applied using nearest neighbor analysis and Geographic Information System (GIS) techniques. A total of 38 tourism attractions were identified, including 17 natural attractions, 17 artificial attractions, and four cultural attractions; all exhibiting dispersed distribution patterns. There are 32 hotels with random distribution patterns and 178 restaurants that are clustered. Natural attractions are characterized by hilly terrain, forests, valleys, and rivers, which result in physical separation between some sites. In contrast, artificial and cultural attractions tend to be concentrated in more accessible areas, particularly along main routes. Notably, villages such as Cikahuripan, Cikidang, Mekarwangi, Suntenjaya, Wangunharja, and Wangunsari contain tourism attractions but lack adequate supporting facilities, including hotels and restaurants. The spatial allocation of tourism attractions, accommodations, and restaurants significantly influences the achievement of the SDGs. Tourism contributes to 14 of the 17 SDGs, especially SDG 8 (promoting economic opportunities), SDG 1 (reducing poverty), and SDG 5 (advancing gender equality). © 2026 Tim Pengembang Jurnal UPI.

    DOI: 10.1109/INCITEST64888.2024.11121515

    Abstract

    E-Planning is an application used to help formulate policies in preparing internet-based regional development planning documents. Minister of Internal Affairs Regulation No. 90/2019 concerning the Regional Government Information System (SIPD) has obliged City/Regency governments throughout Indonesia to implement SIPD gradually starting in 2021 using an application developed by the Ministry of Home Affairs, namely SIPD with the web address https://sipd.kemendagri.go.id. The SIPD e-Planning application that was built and developed contains e-Database, e-Planning, eMonev, and e-Reporting to build a more effective, efficient, lawabiding relationship between central and local governance, accelerating bureaucratic reform to strengthen regional autonomy. For the needs of evaluation and application development, it is necessary to conduct research on the user experience of the SIPD e-Planning application. The SIPD ePlanning application was introduced to the Regional Government in conjunction with the emergence of the COVID19 pandemic, which began in early 2020. Therefore, it is also necessary to examine how the SIPD e-Planning application services during the pandemic. This study aims to evaluate the user experience of the SIPD e-Planning application in Luwu Regency and Gowa Regency, especially during the COVID-19 pandemic. The research was conducted using the meCUE Questionnaire method and interviews with application users. An evaluation of the user experience of the SIPD e-Planning application shows that the SIPD e-Planning application is handy and very appropriate for use in achieving e-Planning goals. The SIPD e-Planning application is easy to use and has a userfriendly interface. Development planning during the COVID-19 pandemic was very effective using the SIPD e-Planning application because it can be accessed online so that it is not affected by changes in work schedules caused by work from home (WFH) policies during the COVID-19 pandemic. The overall evaluation of user experience shows that Luwu Regency and Gowa Regency users have relatively similar experiences with the SIPD e-Planning application. © 2024 IEEE.

    Designing A Geographical Information System for Houses Not Feasible As Supporters of Policy

    Hardiyana B. ; Wibawa J.C.

    DOI: 10.1088/1757-899X/662/2/022103

    Abstract:

    The implementation of social welfare development programs in developing countries is generally focused on the empowerment program of the poor, which is more nuanced in a participatory approach involving the community, business and government. empowerment is considered appropriate to be one of the policy choices in the development of social welfare today. The development of social welfare based on the principle of empowerment is intended that in the handling of the poor it must be done through increasing the capacity of human resources to increase independence (Law Number 13 of 2011). Regional development has an impact on national development. Poverty reduction policies realized through community empowerment programs have become the main agenda and priori development in Baleendah Subdistrict, especially Rancamanyar Village. One of the poverty alleviation programs through community empowerment carried out in Rancamanyar Village is the Housing Assistance Program for uninhabitable houses. Various local government efforts to reduce the number of uninhabitable houses are still considered uneven. With the limited management and processing of survey data in the regions, it is one of the factors that do not help the existing policies. With the construction of a geographic information system for uninhabitable homes, one of the efforts that must be taken by the local government in order to support and assist in making decisions for uninhabitable houses is to conduct geographical analysis and mapping of uninhabitable houses in Rancamanyar Village, so that help is not wrong target. © Published under licence by IOP Publishing Ltd.
