2026-07-17T07:57:13+00:00

Penerapan ISO 50001:2018 melalui energy review telah banyak digunakan untuk mengidentifikasi Energy Baseline (EnB), Energy Performance Indicator (EnPI), dan Significant Energy Use (SEU), namun pendekatan ini belum mampu memberikan rekomendasi kondisi operasi optimum untuk meningkatkan efisiensi energi secara terukur. Penelitian ini bertujuan mengembangkan Integrated Energy Decision Framework yang mengintegrasikan energy review dengan simulasi proses sebagai dasar pengambilan keputusan operasional pada sistem utilitas industri. Studi dilakukan di Plant C industri petrokimia melalui tahapan data cleansing, perhitungan konsumsi energi, penyusunan EnB dan EnPI menggunakan regresi linier, serta identifikasi SEU melalui analisis Pareto. Unit absorption refrigerator yang teridentifikasi sebagai SEU dimodelkan menggunakan perangkat lunak simulasi proses dan dioptimasi melalui sensitivity analysis terhadap temperatur generator, temperatur cooling water, dan laju alir refrigeran. Hasil penelitian menunjukkan bahwa peningkatan laju alir refrigeran memberikan kinerja terbaik dengan penurunan konsumsi steam sebesar 6,4–11,9% dan peningkatan Coefficient of Performance (COP) sebesar 7,6–14,9%. Steam ekses hasil optimasi selanjutnya dapat dimanfaatkan untuk meningkatkan pembangkitan listrik melalui steam turbine generator atau mengurangi konsumsi gas alam pada boiler sesuai kebutuhan utilitas. Integrasi energy review dan simulasi proses terbukti menghasilkan kerangka pendukung keputusan yang lebih efektif dibandingkan pendekatan konvensional, sehingga mampu meningkatkan efisiensi energi sekaligus memberikan manfaat ekonomi pada sistem utilitas industri. Penelitian ini berkontribusi pada pengembangan ilmu manajemen energi industri melalui integrasi sistem manajemen energi berbasis ISO 50001 dengan optimasi proses, serta menyediakan dasar ilmiah bagi pengambilan keputusan operasional yang adaptif dalam meningkatkan efisiensi energi dan menurunkan biaya operasi pada industri kimia dengan sistem utilitas terintegrasi.

2026-07-07T07:07:53+00:00

This study aims to assess the effectiveness of the implementation of the Digital Village Application(DIGIDES) in improving public services in Gebang Ilir Village,Cirebon Regency.The problems faced include low digital literacy of the community,limited internet infrastructure,and a lack of experts within the village apparatus. This study used a descriptive qualilative approach with data collection techniques throught in-depth interviews with village heads,operators,and comunity.Research analysisuses the DeLone and McLean Information system Success model (2003) which includes system quality, information quality,Usage,User Satisfaction and benefits.The results of the study indicated that DIGIDES has a fairly good system and information quality and is able to increase the efficiency of public services in the village.However,the level of use by the community is still relatively low and user satisfaction is not optimal due to technical and social constraints.In addition.there is a gap between e-Government policies at the national level and implementation at the local level. The conclusion of this study shows that DIGIDES is quite effective,but still requires increased training,socialization, internet network improvements,and the provision of self- service facilities to support more transparent,effective and efficient public services

Analysis of the Dynamics of Changes in the Coastline of Cirebon City in 2010-2025 Using Geographic Information System (GIS) Technology

2026-07-17T08:01:31+00:00

Coastal areas are dynamic transition zones, experiencing continuous physical changes due to the interaction between natural processes and anthropogenic activities. As a coastal area on the north coast of Java, Cirebon City faces serious challenges related to shoreline dynamics influenced by sedimentation, abrasion, infrastructure development, and land use changes. This study aims to analyze the dynamics of shoreline change in Cirebon City during the period 2010–2025 using Geographic Information System (GIS) technology and remote sensing. This study applied a mixed-method approach that integrates spatial quantitative analysis and qualitative descriptive analysis. Multitemporal satellite imagery from Landsat 7 (2010 and 2015) and Sentinel-2 (2020 and 2025) was processed using the Normalized Difference Water Index (NDWI) algorithm to extract shoreline positions. Furthermore, the Digital Shoreline Analysis System (DSAS) method with End Point Rate (EPR) calculations was applied to determine the rate and spatial distribution of abrasion and accretion. The results of the study indicate that the Cirebon City coastline experienced significant spatial changes during the 15 years of observation, with accretion processes dominating most coastal segments. The average rate of shoreline change reached 5.66 meters/year, with the highest accretion rate of 40.95 meters/year and maximum abrasion of -4.63 meters/year. The most prominent changes occurred in Lemahwungkuk District, primarily due to sedimentation processes and anthropogenic activities such as coastal reclamation and port development. These findings confirm that the integration of GIS, remote sensing, and field observations provides an effective approach to monitoring shoreline dynamics and supporting sustainable coastal management planning in urban areas.

E-Government Innovation: Digital Identity Services in Cirebon Regency

2026-07-07T04:25:16+00:00

The development of information technology has encouraged the government to innovate public services through the implementation of e-government, one of which is the Digital Population Identity (Identitas Kependudukan Digital/IKD) by the Cirebon Regency Population and Civil Registration Office (Dinas Kependudukan dan Pencatatan Sipil). IKD was implemented as an effort to transform digital-based population administration services to be more practical, fast, and efficient. However, the implementation of IKD still faces several obstacles, such as low public understanding of digital technology, inadequate socialization, limited internet access, and technical difficulties during the activation and use of the application. Some people also still prefer physical documents, as these are considered easier to use. This study aims to analyze the implementation of IKD in public services in Cirebon Regency, identify the obstacles faced, and determine the role of IKD in improving the quality of public services. The study employed a qualitative method using interview and document analysis techniques. The research informants were community members who use the IKD application. The results showed that IKD makes it easier for the public to access population administration services digitally. IKD is considered practical and efficient and is able to reduce the need for people to come directly to service offices. Although there were obstacles in the initial stages of use, assistance from officers helped the community understand how to use the IKD application.

The Legal Liability of Business Actors for Products Not Described in E-Commerce Transactions

2026-07-21T07:35:51+00:00

The development of electronic transactions through e-commerce platforms has changed global trade patterns, but has given rise to serious legal issues related to the discrepancy between products received by consumers and the descriptions displayed by business actors. This study aims to analyze the legal status of product descriptions in electronic sales agreements and construct the form of legal responsibility of business actors for products that do not match the descriptions in e-commerce transactions. This study uses legal protection theory, contract theory, and legal responsibility theory as the analytical framework. The method used is normative legal research with a statutory approach, a conceptual approach, and a case approach, supported by limited interviews with legal academics. Legal materials were obtained from primary, secondary, and tertiary legal materials, which were analyzed using normative qualitative methods with grammatical, historical, and teleological interpretations. The research findings indicate that product descriptions in e-commerce transactions are an integral part of the legally binding agreement between the parties based on Article 1320 and Article 1458 of the Civil Code. Discrepancies between product descriptions and goods received by consumers can be qualified as a breach of contract and a violation of consumer rights based on Article 4 letter c, Article 7 letter b, and Article 8 paragraph (1) letter f of the Consumer Protection Law. Legal liability for business actors can be pursued through three legal domains: civil liability based on breach of contract, administrative liability based on Government Regulation Number 80 of 2019, and consumer protection liability based on the principle of strict liability as stipulated in Article 19 of the Consumer Protection Law. This research conceptually proposes the development of a shared responsibility framework between marketplace platforms and business actors to ensure more effective consumer protection in digital transactions.
