Optimalisasi Penerapan Sistem Rainwater Harvesting (RWH) di Lingkungan Politeknik Negeri Bandung dalam Rangka Konservasi Sumber Daya Air
No full textThis study aims to optimize the Rainwater Harvesting (RWH) system at Bandung State Polytechnic as a strategy for water resource conservation and strengthening the Green Campus concept. The research was conducted by identifying the existing condition of the RWH system at 25 campus building points, analyzing hydrological potential using BMKG rainfall data from 2014–2024, as well as evaluating efficiency and developing technical optimization recommendations. The existing RWH system is dominated by tanks with a capacity of 1,050–2,000 liters, which do not yet function optimally due to limited capacity, channel blockages, and variations in pipe diameter. The analysis shows an average annual rainfall of 2,831 mm with a potential rainwater catchment of up to 70 m³ per month, sufficient to meet 25–30% of the campus's non-potable water demand. System optimization is proposed by increasing tank capacity to 5,000–10,000 liters, using 3–4 inch pipes, and implementing multi-layer filtration and automated control, thus increasing system efficiency to 40–60%. The integrated system prototype in classrooms and laboratories has been proven to reduce PDAM water consumption by 40% and surface runoff by up to 35%. The research outcomes support the achievement of UI GreenMetric water conservation indicators and contribute to the realization of Sustainable Development Goals (SDGs) points 6 and 13. This study provides recommendations for an adaptive RWH system replication model for other educational institutions in Indonesia to manage water resources sustainably and efficiently.Penelitian ini bertujuan untuk mengoptimalisasi sistem Rainwater Harvesting (RWH) di lingkungan Politeknik Negeri Bandung sebagai strategi konservasi sumber daya air dan penguatan konsep Green Campus. Studi dilakukan melalui identifikasi kondisi eksisting sistem RWH pada 25 titik bangunan kampus, analisis potensi hidrologi menggunakan data curah hujan BMKG 2014–2024, serta evaluasi efisiensi dan penyusunan rekomendasi optimalisasi teknis. Sistem RWH eksisting didominasi oleh tangki kapasitas 1.050–2.000 liter yang belum berfungsi optimal akibat keterbatasan kapasitas, penyumbatan saluran, dan variasi diameter pipa. Analisis menunjukkan rata-rata curah hujan tahunan sebesar 2.831 mm dengan potensi tangkapan air hujan mencapai 70 m³ per bulan, yang mampu memenuhi 25–30% kebutuhan air non-potabel kampus. Optimalisasi sistem diusulkan melalui peningkatan kapasitas tangki menjadi 5.000–10.000 liter, penggunaan pipa 3–4 inci, serta penerapan filtrasi berlapis dan kontrol otomatis, sehingga meningkatkan efisiensi sistem hingga 40–60%. Prototype sistem terintegrasi pada gedung kelas dan laboratorium terbukti dapat menurunkan konsumsi air PDAM sebesar 40% dan mengurangi limpasan permukaan hingga 35%. Hasil penelitian mendukung upaya pencapaian indikator UI GreenMetric kategori Water Conservation, serta berkontribusi pada realisasi Tujuan Pembangunan Berkelanjutan (SDGs) poin 6 dan 13. Penelitian ini memberikan rekomendasi model replikasi sistem RWH adaptif bagi institusi pendidikan lain di Indonesia dalam mengelola sumber daya air secara berkelanjutan dan efisie
Evaluasi Jaringan Drainse Perkotaan di Jalan Raya Kemang, Kabupaten Bogor
No full textInundation on Jalan Raya Kemang (the Parung-Bogor road section in the Kemang area) is a common problem, especially during the high-intensity rainy season, disrupting public mobility and causing traffic congestion. This study aims to identify the factors causing the inundation and to evaluate the existing conditions of the drainage network system in the area. The methods used include hydrological and hydraulic analysis. Hydrological analysis is utilized to calculate the design flood discharge, while hydraulic analysis is used to analyze the capacity of the existing drainage channels.The results of the hydrological analysis show that the total design flood discharge from upstream to downstream is 1.08 m³/s. The hydraulic analysis on the existing channel dimensions of (1.2 x 1) meters indicates a channel capacity of 1.51 m³/s. Theoretically, the channel dimensions are capable of accommodating the design discharge. However, field observations show that the main factor causing the inundation is the presence of mud and sand sedimentation, approximately 30 cm high, inside the channels. This sedimentation causes a significant reduction in flow capacity. After accounting for the sedimentation, the channel capacity decreases to 0.962 m³/s, which is smaller than the design discharge at the inundation point (0.977 m³/s), causing water to overflow onto the road. Furthermore, the lack of drainage inlets is also a contributing factor to the inundation.It is concluded that the inundation on Jalan Raya Kemang is not caused by inadequate channel dimensions but rather by high sedimentation and a lack of drainage inletsGenangan air di Jalan Raya Kemang (Jalan Raya Parung - Bogor Kawasan Kemang) merupakan permasalahan yang sering terjadi, terutama saat musim hujan dengan intensitas tinggi, mengganggu mobilitas masyarakat dan menyebabkan kemacetan arus lalu lintas. Penelitian ini bertujuan untuk mengidintifikasi faktor penyebab genangan dan mengevaluasi kondisi eksisting sistem jaringan drainase di kawasan tersebut. Metode yang digunakan meliputi analisis hidrologi dan hidrolika. Analisis hidrogi digunakan untuk menghitung debit banjir rencana sedangkan analisis hidrolika digunakan untuk mengalisis kapasitas saluran eksisting drainase. Hasil analisis hidrologi mendapatkan total debit banjir rencana keseluruhan dari hulu sampai hilir sebesar 1,08 /dtk. Analisis hidrolika pada dimensi saluran eksisting dengan dimensi (1,2 x 1) menjukan kapasitas saluran sebesar 1,51 m3/dtk. Secara teoritis, dimensi saluran mampu menampung debit rencana, namun hasil observasi menunjukan faktor utama penyebab genangan adalah adanya sedimentasi lumpur dan pasir setinggi kurang lebih 30 cm di dalam saluran, sedimentasi ini menyebabkan penurunan kapasitas aliran secara signifikan. Setelah memperhitungkan sedimentasi kapasitas saluran turun menjadi 0,962 /dtk, lebih kecil dari debit rencana pada titik genangan 0,977 /dtk sehingga air meluap ke jalan, selain itu kurangnya inlet drainase juga menjadi faktor penunjang genangan. Disimpulkan bahwa genangan di jalan raya kemang bukan di sebabkan oleh dimensi saluran yang tidak memadai melainkan dikarenakan oleh faktor sedimentasi yang tinggi dan kurangnya inlet drainase
Analisis Time Cost Trade Off sebagai Strategi Percepatan Proyek untuk Efisiensi Pembangunan Gedung Laboratorium Teknik 4 Institut Teknologi Sumatera
No full textProject delays in construction are complex issues that have a significant impact on increasing costs and completion time. This study aims to analyze the optimal project acceleration strategy for the construction of the Engineering Laboratory Building (GLT) 4 at ITERA, which is experiencing delays, by applying the Time Cost Trade Off (TCTO) method. This quantitative research compares three alternative acceleration strategies: adding working hours (overtime), adding work shifts, and adding labor and heavy equipment. Primary data was obtained through interviews with the contractor, while secondary data included the time schedule, the Budget Plan (RAB), and other project documents. The analysis was conducted by compiling a critical work network, calculating normal duration and costs, and analyzing the crash duration and crash cost for each alternative. The results show that the project's normal condition has a duration of 224 days with a total cost of Rp 16,927,594,301. All three acceleration strategies proved effective in reducing both duration and cost. The strategy of adding labor and heavy equipment proved to be the most optimal, resulting in a duration of 163 days (time efficiency of 27.23%) with the highest cost efficiency of 5.75%. The alternative of adding work shifts resulted in the fastest duration of 161 days (time efficiency of 28.13%), but with lower cost efficiency (4.92%). Meanwhile, adding overtime hours was the weakest alternative with a duration of 178 days (time efficiency of 20.54%) and a cost efficiency of 3.51%. The research confirms that adding resources (labor and equipment) provides the most beneficial time-cost trade-off for this project, where the indirect cost savings from shortening the heavy equipment rental period are greater than the additional direct costs.Keterlambatan proyek konstruksi merupakan permasalahan kompleks yang berdampak signifikan terhadap peningkatan biaya dan waktu penyelesaian. Penelitian ini bertujuan untuk menganalisis strategi percepatan proyek yang optimal pada Pembangunan Gedung Laboratorium Teknik (GLT) 4 ITERA yang mengalami keterlambatan dengan menerapkan metode Time Cost Trade Off (TCTO). Penelitian kuantitatif ini membandingkan tiga alternatif strategi percepatan, yaitu penambahan jam kerja (lembur), penambahan shift kerja, serta penambahan tenaga kerja dan alat berat. Data primer diperoleh melalui wawancara dengan kontraktor, sedangkan data sekunder meliputi time schedule, Rencana Anggaran Biaya (RAB), dan dokumen proyek lainnya. Analisis dilakukan dengan menyusun jaringan kerja kritis, menghitung durasi dan biaya normal, serta menganalisis crash duration dan crash cost untuk setiap alternatif. Hasil penelitian menunjukkan bahwa kondisi normal proyek memiliki durasi 224 hari dengan biaya total Rp 16.927.594.301. Ketiga strategi percepatan terbukti efektif memangkas durasi dan biaya. Strategi penambahan tenaga kerja dan alat berat terbukti paling optimal, menghasilkan durasi 163 hari (efisiensi waktu 27,23%) dengan efisiensi biaya tertinggi sebesar 5,75%. Alternatif penambahan shift kerja menghasilkan durasi tercepat yaitu 161 hari (efisiensi waktu 28,13%), namun dengan efisiensi biaya lebih rendah (4,92%). Sementara penambahan jam lembur menjadi alternatif terlemah dengan durasi 178 hari (efisiensi waktu 20,54%) dan efisiensi biaya 3,51%. Penelitian mengkonfirmasi bahwa penambahan sumber daya (tenaga kerja dan alat) memberikan trade-off waktu-biaya paling menguntungkan untuk proyek ini, di mana penghematan biaya tidak langsung dari pemendekan durasi penyewaan alat berat lebih besar daripada tambahan biaya langsung
Implementasi dan Pengendalian Sistem Manajemen Keselamatan dan Kesehatan Kerja (SMK3) terhadap Kinerja K3 pada Proyek Konstruksi
No full textOccupational Safety and Health (OSH) is a crucial aspect in construction projects, which are characterized by a high risk of workplace accidents. Improving OSH performance requires effective implementation of the Occupational Safety and Health Management System (OSHMS) as well as continuous control mechanisms. This study aims to analyze the effect of OSHMS implementation and control on OSH performance in construction projects. A quantitative approach was employed using a survey method by distributing questionnaires to respondents directly involved in construction project activities. The collected data were analyzed using the Partial Least Squares–Structural Equation Modeling (PLS-SEM) method. The results indicate that OSHMS implementation has a positive and significant effect on OSH performance. In addition, OSHMS control also has a positive and significant effect on OSH performance, although its influence is lower than that of OSHMS implementation. These findings suggest that the implementation and control of OSHMS are complementary aspects in improving OSH performance in construction projects.Keselamatan dan Kesehatan Kerja (K3) merupakan aspek penting dalam pelaksanaan proyek konstruksi yang memiliki tingkat risiko kecelakaan kerja tinggi.

Temuan ini menunjukkan bahwa implementasi dan pengendalian SMK3 merupakan dua aspek yang saling melengkapi dalam meningkatkan kinerja K3 pada proyek konstruksi
The Effect of Asta Brata Leadership and Organizational Culture on Employee Commitment Through Job Satisfaction at The Pratama Sidhi Sai Clinic Badung Bali
No full textThis study aims to analyze the influence of Asta Brata leadership and organizational culture on employee commitment with job satisfaction as a mediating variable at Klinik Pratama Sidhi Sai, Bali. Using a quantitative explanatory design, data were collected through questionnaires administered to all employees and analyzed using Structural Equation Modeling–Partial Least Squares (SEM–PLS). The results show that Asta Brata leadership has a significant positive effect on job satisfaction and employee commitment, while organizational culture significantly affects job satisfaction but does not directly influence commitment. Job satisfaction strongly affects employee commitment and mediates the relationship between leadership and commitment (partial mediation) as well as between organizational culture and commitment (full mediation). The research model explains 87% of the variance in job satisfaction and 93.2% of the variance in employee commitment. These findings emphasize that local wisdom–based leadership and a supportive organizational culture enhance employee commitment primarily through increased job satisfaction, offering strategic implications for strengthening loyalty, satisfaction, and service quality in healthcare institutions
Transformation of Gender Equality Values in the Household from an Islamic Family Law Perspective
No full textThis study explores the transformation of gender equality values in Muslim households in Soppeng Riaja Subdistrict, Barru Regency, South Sulawesi, Indonesia, a rural area showing relatively advanced gender equality practices in public sectors such as governance, education, and health, while maintaining traditional role divisions in primary sectors. Employing a qualitative approach with a normative-sociological perspective, the research combines in-depth interviews with six purposively selected married women who balance domestic responsibilities and public work, non-participant observation, and documentation over six months. Findings reveal that gender equality is implemented through three key dimensions: justice (evident in deliberative decision-making and equal educational access), togetherness (reflected in flexible domestic task-sharing based on situational needs), and responsibility (demonstrated by women’s active economic participation and financial management). The community adapts to these changes through gradual strategies, including shifting mindsets toward mutual understanding, reinterpreting religious and cultural beliefs to emphasize Islamic principles of justice and partnership, and altering daily behaviors to foster cooperation. Despite progress, challenges persist, including patriarchal cultural remnants, women’s double burden, and limited understanding of gender equality concepts. The study concludes that gender equality in this context emerges adaptively by harmoniously integrating Islamic teachings, Bugis-Makassar customs, and modern demands, offering a contextual model for Muslim communities in Indonesia without rejecting traditional or religious values.

CORRELATION BETWEEN HIGH-PURINE DIET PATTERNS AND URIC ACID LEVELS AMONG THE ELDERLY IN PASURUAN REGENCY
No full textHyperuricemia is a common metabolic disorder among the elderly and is closely associated with gout, renal impairment, and cardiovascular disease. A high-purine diet is one of the major modifiable factors influencing serum uric acid levels, yet evidence among Indonesian older adults remains limited. This study aimed to examine the correlation between high-purine dietary patterns and serum uric acid levels among elderly individuals in Pasuruan Regency, East Java. A cross-sectional analytic observational design was applied to 120 respondents aged ≥60 years, selected using a simple random sampling technique. Data were obtained through structured interviews, a validated Semi-Quantitative Food Frequency Questionnaire (SQ-FFQ), and laboratory testing of serum uric acid levels. The results revealed a moderate positive correlation between the High-Purine Diet Score (HPDS) and serum uric acid concentration (r=0.42; p<0.001). The overall prevalence of hyperuricemia was 23.3%, with the highest proportion (37.5%) observed among participants with high HPDS. The study concludes that higher purine intake is significantly associated with elevated serum uric acid levels in the elderly, emphasizing the need for dietary counseling and public health interventions focused on balanced nutrition in older populations
THE ROLE OF HBA1C IN CHRONIC KIDNEY DISEASE PROGRESSION IN TYPE 2 DIABETES MELLITUS PATIENTS: A LITERATURE REVIEW
No full textType 2 diabetes mellitus (T2DM) is a leading cause of chronic kidney disease (CKD), contributing significantly to global morbidity, mortality, and healthcare burden. Glycemic control, primarily assessed by hemoglobin A1c (HbA1c), has traditionally been considered essential for preventing microvascular complications, including diabetic kidney disease (DKD). However, the relationship between HbA1c and CKD progression in patients with established CKD remains complex and controversial, particularly in advanced stages. This literature review, conducted according to PRISMA 2020 guidelines, systematically examined evidence from 10 selected studies (published 2013–2025) exploring the role of HbA1c in CKD progression among patients with T2DM. Studies included observational cohorts, longitudinal analyses, and one review, encompassing diverse populations and CKD stages. Key findings indicate that in early-to-moderate CKD (stages 1–3/4), higher mean HbA1c levels consistently predict faster eGFR decline and increased risk of progression, supporting the benefit of stricter glycemic control in these stages. In advanced CKD (stages 4–5), intensive glycemic control shows limited renal protective effects, with stronger associations observed for reducing cardiovascular events and mortality rather than slowing renal progression. HbA1c variability emerged as an independent predictor of adverse renal outcomes, including microalbuminuria development, non-linear eGFR trajectories, and rapid progression to end-stage kidney disease, potentially mediated by oxidative stress. Additionally, HbA1c reliability decreases in severe CKD due to altered red blood cell turnover and anemia, suggesting the need for alternative markers such as fructosamine. Patient factors, including African-Caribbean ethnicity, further modify these relationships. HbA1c plays a stage-dependent role in CKD progression in T2DM. Clinical management should prioritize individualized, stage-specific targets, emphasize glycemic stability, incorporate alternative monitoring tools in advanced disease, and account for patient-specific risk factors to optimize outcomes while minimizing hypoglycemia risk
