Abstract

This study examined the effects of professionalism, workload, and organizational climate on employee productivity at the Secretariat of the Kupang City Regional House of Representatives (DPRD). A quantitative associative-causal research design was employed to test the relationships among the variables. Data were collected through questionnaires, interviews, and documentation from all 97 employees using a saturated sampling technique. Multiple linear regression analysis was applied to examine the partial and simultaneous effects of the independent variables on productivity. The findings revealed that professionalism (β = 0.144; p = 0.008), workload (β = 0.238; p = 0.001), and organizational climate (β = 0.651; p < 0.001) each had a positive and significant effect on employee productivity. Simultaneously, the three variables also significantly influenced productivity (F = 365.582; p < 0.001). The coefficient of determination (R² = 0.922) indicated that 92.2% of the variance in productivity was explained by the three predictors, demonstrating a very strong relationship. Organizational climate emerged as the strongest predictor, highlighting its critical role in enhancing employee performance within the public sector. These findings suggest that managers in regional legislative secretariats and other government institutions should prioritize strengthening organizational climate through effective leadership, trust, open communication, and organizational support while continuously improving employee professionalism and maintaining balanced workload management. Implementing these strategies is expected to enhance productivity, strengthen organizational performance, improve the quality and accountability of public services, and support the achievement of organizational goals in government institutions through sustainable human resource management practices.

Abstract

Permintaan terhadap hunian apartemen di Kota Bandung terus meningkat seiring pertumbuhan penduduk dan urbanisasi, terutama pada apartemen yang berlokasi di kawasan strategis seperti kawasan pendidikan, salah satunya Apartemen The Jarrdin. Pola perilaku penghuni pada ruang hunian vertikal sangat dipengaruhi oleh cara ruang dirancang dan diatur, khususnya pada transisi dari ruang publik dan semi-publik menuju ruang yang lebih privat, yaitu dari area lobby dan fasilitas bersama menuju area lift penghuni. Desain ruang yang kurang efisien dan tidak memperhatikan pola perilaku penghuni, yang membiarkan akses bebas menuju area lift penghuni, berpotensi menurunkan rasa aman sekaligus memengaruhi pola perilaku dan interaksi sosial penghuni. Penelitian ini bertujuan mengidentifikasi kelemahan desain eksisting dan merumuskan alternatif desain untuk meningkatkan rasa aman serta interaksi sosial antarpenghuni. Penelitian menggunakan metode kualitatif melalui observasi lapangan dan wawancara terhadap penghuni serta pekerja apartemen, dilengkapi analisis behavioral mapping pada area lantai dasar. Hasil penelitian menunjukkan bahwa penataan kembali ruang pada lantai dasar dan pembatasan akses dari ruang publik dan semi-publik menuju ruang privat mampu meningkatkan rasa aman penghuni. Disimpulkan bahwa pengendalian akses, penguatan pengawasan alami, dan penataan ruang yang lebih terstruktur berpengaruh positif terhadap pola perilaku penghuni. Implikasinya, prinsip pengendalian akses dan pengawasan alami perlu dipertimbangkan sejak tahap perancangan apartemen guna menciptakan lingkungan hunian yang lebih aman, nyaman, dan mendukung interaksi sosial penghuni.

Abstract

The need for reliable alternative sources of electricity continues to increase, especially in areas that are not yet reached by PLN's network and in renewable energy systems based on solar panels and batteries. Inverters play a key role in such systems because they convert DC voltage into AC that household appliances need. This study aims to design and test a simple inverter circuit capable of converting 12 Volt DC voltage into 220 Volt AC voltage. The inverter was designed using a 12V battery source, D313 transistor as an electronic switching component, and a center tap transformer as a step-up transformer. The research method used was an experimental method through stages of circuit design, assembly, testing, and analysis of inverter performance using LED lamp loads of 5 Watt, 10 Watt, and 15 Watt. Parameters measured included input voltage, input current, output voltage, output current, and output frequency. The test results showed that the inverter was able to produce AC output voltages of 219 Volt, 216 Volt, and 211 Volt respectively with frequencies close to 50 Hz. The increase in load caused a slight decrease in output voltage and frequency due to increased current and power losses in the circuit. Overall, the inverter succeeded in converting 12 Volt DC into AC voltage close to household electricity standards and was stable enough for light electrical loads.

Abstract

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.

Abstract

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.
