Evaluasi Efektivitas Drainase Jalan Kusuma Bangsa dalam Mengatasi Intensitas Banjir Tahunan dan Strategi Mitigasi Genangan Air di Kabupaten Lamongan
Full text linkThe increasing urban growth in Lamongan Regency, Indonesia, has led to various issues and challenges related to stormwater management and flood risk in Lamongan District, particularly along Kusuma Bangsa Street. This study aims to evaluate the drainage system on Kusuma Bangsa Street by analyzing the capacity of drainage channels using a hydrological and hydraulic analysis approach. Rainfall data with return periods of 2, 5, and 10 years were used to estimate flood discharge. The results indicate that the flood risk in the area has significantly increased, as most existing drainage channels are unable to accommodate the planned flood discharge. Poor maintenance and excessive waste accumulation in certain sections of the channels further reduce the drainage system’s capacity. This evaluation is crucial for formulating strategies to improve drainage channels, mitigate flood risk, and enhance the resilience of urban infrastructure in Lamongan District. Flood risk mitigation strategies for this road include redesigning critical drainage sections, implementing green infrastructure solutions to enhance water absorption and reduce surface runoff, and adopting a routine maintenance schedule. These measures are expected to provide a more sustainable approach to urban flood risk management and support the sustainable development of the region.Pertumbuhan perkotaan yang meningkat di Kabupaten Lamongan, Indonesia, telah menyebabkan berbagai masalah dan tantangan terkait pengelolaan air hujan dan risiko banjir di Kecamatan Lamongan, khususnya di sepanjang Jalan Kusuma Bangsa.

Analysis of Factors Influencing Contractor Performance in Supporting Infrastructure Sovereignty in North Sulawesi
Full text linkThis research analyzes the factors influencing contractor performance in supporting infrastructure sovereignty in North Sulawesi. The research method uses a quantitative descriptive approach by collecting primary data through questionnaires and structured interviews with contractors involved in infrastructure projects. A cluster sampling technique was used to select samples from various regions in North Sulawesi. Analysis shows that the main factors influencing contractor performance are the availability of capital, competition from similar projects, and the timeliness of client payments. The availability of adequate capital is considered crucial to ensure the smooth implementation of the project. Intense competition compels contractors to lower prices, impacting profit margins and work quality. Timeliness of payments is essential to maintain the contractor\u27s cash flow and financial stability. Other factors, such as changes in government regulations and licensing bureaucracy, also influence performance, but with more variable effects. This research provides recommendations for contractors to strengthen financial management, adapt to competitive pressures, and improve collaboration with stakeholders to ensure the success of infrastructure projects.Penelitian ini menganalisis faktor-faktor yang memengaruhi kinerja kontraktor dalam mendukung kedaulatan infrastruktur di Sulawesi Utara.

Analisis Laju Sedimen Berdasarkan Data Unsteady Flow Real Time Dengan HEC-RAS di DAS Bomo Banyuwangi
Full text linkThe 2018 flash flood in Banyuwangi Regency highlighted the role of sedimentation in increasing disaster risks. This study aims to analyze sedimentation rates based on real-time unsteady flow data during the rainy and dry seasons, understand the relationship between unsteady flow and sedimentation, and evaluate the role of HEC-RAS in mitigating sedimentation-related risks. Hydrometric measurements were conducted in real-time over seven days in both seasons. Data were analyzed using HEC-RAS and validated using the Mean Absolute Error (MAE) method of bathymetric measurements. The results show that sedimentation rates were higher during the rainy season (2.77 m³/day) compared to the dry season (1.33 m³/day) due to increased discharge and flow velocity. Flow velocity correlates more strongly with sedimentation than discharge, with regression values of 0.8257 in the dry season and 0.4072 in the rainy season. Flood modeling with HEC-RAS indicates that sedimentation increases flood risks, particularly in downstream areas. Therefore, mitigation measures such as river normalization, embankment construction, drainage optimization, and upstream soil conservation are necessary. These findings also support early warning systems to enhance community preparedness for sedimentation-induced floods.Banjir bandang di Kabupaten Banyuwangi tahun 2018 menunjukkan sedimentasi berperan dalam meningkatkan risiko bencana. Penelitian ini bertujuan untuk menganalisis laju sedimentasi berdasarkan data unsteady flow real-time pada musim hujan dan kemarau, memahami hubungan antara unsteady flow dan sedimentasi, serta mengevaluasi peran HEC-RAS dalam mitigasi risiko akibat sedimentasi. Pengukuran hidrometri dilakukan secara real-time selama 7 hari di dua musim. Data dianalisis dengan HEC-RAS dan divalidasi menggunakan metode Mean Absolute Error (MAE) dari pengukuran batimetri. Hasil menunjukkan laju sedimentasi lebih tinggi pada musim hujan (2.77 m³/hari) dibandingkan musim kemarau (1.33 m³/hari) akibat debit dan kecepatan aliran yang lebih besar. Kecepatan aliran memiliki korelasi lebih tinggi terhadap sedimentasi dibanding debit, dengan regresi 0.8257 di musim kemarau dan 0.4072 di musim hujan. Pemodelan banjir dengan HEC-RAS menunjukkan bahwa sedimentasi memperbesar risiko luapan, terutama di hilir. Oleh karena itu, mitigasi diperlukan melalui normalisasi sungai, pembangunan tanggul, optimalisasi drainase, serta konservasi tanah di hulu. Hasil ini juga mendukung sistem peringatan dini untuk meningkatkan kesiapsiagaan masyarakat terhadap banjir akibat sedimentasi

Analisis Kontribusi dan Laju Pertumbuhan Pajak Restoran terhadap pendapatan asli daerah kota Ambon
Full text linkIn Law Number 28 of 2009 on Regional Taxes and Levies, local governments are granted the authority to explore financial resource potentials by establishing new types of taxes and levies not previously regulated, provided they meet the established criteria and reflect the aspirations of the community. Regional taxes, as one of the components of Local Revenue (PAD), are used to finance various regional expenditures, both routine and for development purposes. Regional taxes are expected to be a vital source of financing for government administration and regional development, as well as contribute to the improvement and equitable distribution of community welfare. Regional taxes are divided into two main categories: provincial regional taxes and regency/city regional taxes. This study aims to determine the contribution and growth rate of restaurant taxes in Ambon City. The research method used is descriptive quantitative analysis, particularly in describing the results of calculations of the contribution and growth rate of restaurant taxes in the local revenue of Ambon City. The research object is the Ambon City Regional Revenue Office. This study shows that the contribution of restaurant taxes over the last five years (2020-2024) has fluctuated, with a significant increase in the growth rate in 2022, but a sharp decline in the following year. The study indicates that the Ambon City government has not been able to maintain and increase the contribution of restaurant taxes in the last five years. This is due to the lack of active involvement from officers in collecting taxes and in socializing the sanctions and payment procedures to the community, particularly to restaurant entrepreneurs.

EVALUATION OF REGIONAL REVENUE AND EXPENDITURE BUDGETS IN THE PALU CITY GOVERNMENT
Full text linkPost-calamity 2018 and the COVID-19 pandemic caused the fiscal performance of Palu City Government to change significantly. For this study, the dynamics of the 2019-2023 Palu City APBD are to be evaluated through growth and variance analysis in an attempt to provide responsive fiscal policy recommendations. Quantitative methods apply by processing the secondary data with APBD reports. Results showed an "explosion-consolidation" trend of spending and revenue variance > 100% in 2019-2022 (conservative) that declined to 96.08% in 2023, indicating the necessity to re-adjust PAD projection assumptions; spending variance increased from 57.05% to 95.26%, reflecting an increase in absorption capacity but not yet quantifiable outcome effectiveness. The trend of revenue-expenditure growth reflects an expansionary response in the crisis phase and consolidation in the recovery phase. These findings underscore the necessity to diversify PAD sources, enhance budget projection models with macro-economic drivers and contingency projections, and strengthen the absorption capacity of spending with e-budgeting and real-time monitoring as the basis for adaptive fiscal policies to improve the resilience and accountability of APBD in disaster-prone areas
Analisa Performa Dessicant Dehumidifier Terhadap Bukaan Damper Pre-Cooling Dengan 10 – 100% Bukaan Pada Aplikasi Clean Room PT Marin Liza Farmasi
Full text linkIndonesia is a country that has a tropical climate, so the content of water vapour in the air is very high, therefore many industrial products are damaged due to high humidity, such as products with hygroscopic material characteristics, for example powder products, medicine tablets, sugar, fertilisers or products with other similar applications. The product will experience clumping so that the resulting product quality is not optimal. On the other hand, high air humidity in a controlled room is certainly very detrimental to the continuity of the production process as well as in clean room applications. Effervescent’s production room at PT Marin Liza Farmasi is an example of a clean room with temperature and RH controlled at 23°C and a water vapour content of 3.47 g/kg with RH less than 20%. If the temperature and water vapour content are not met, production cannot be carried out. The room is positively pressurised with 1177 CFM of fresh air. Damper in pre-cooling is a part that is very influential on the performance of desiccant dehumidifier. Pre-cooling dampers with openings of 10% - 100% openings will affect the value of the bypass factor and air contact factor against the evaporator cooling coil on the pre-cooling AHU, this will also affect the amount of water vapor partial pressure which is influenced by the large temperature coming out of the pre-cooling AHU due to the influence of the evaporator coil temperature. Each damper opening will be tried and analyzed to get the best water vapor content out of the dehumidifier without disturbing the performance of other systems. The damper openings selected for the Effervescent production clean room project at PT Marin Liza Farmasi are the 50% and 60% openings that produce the best dehumidifier performance without interfering with the performance of other systems, which at these openings produce a dehumidifier outlet water vapor content of 1.12 g/kg at the 50% opening with a bypass factor in pre-cooling of 12.26% and 1.2 g/kg at the 60% opening with a bypass factor in pre cooling of 12.90%
