Abstract

Indonesia is a country rich in fauna species, especially ornamental fish. There are about 8500 species of fish and 1300 of them are fish that live in fresh water. This fish diversity is one of the factors that triggers the growth of the economic sector in the hobby sector in the form of maintaining ornamental fish. The maintenance of this ornamental fish requires a container so that it can be enjoyed directly. Commonly used containers are aquariums and glassponds. In the process of making this aquarium and glasspond requires glass material. Glass itself has a special property that is transparent but easily broken. The load on the total volume of water accommodated by the aquarium and glasspond is a major factor in the selection of the thickness and type of glass. This research focuses on 8 mm and 12 mm glass thickness for aquarium and 12 mm tempered type for glasspond. By calculating and analyzing the total water load and the strength of the glass in holding the water load, the optimal glass thickness is obtained in water structures such as aquariums and glassponds.

Abstract

Floods that often occur due to high rainfall inflicts social problems and other social impacts on the community. Therefore. a capable drainage system is necessary which comprises drainage channels with adequate capacities as well as pumps with sufficient capacities and operational rules. The study focuses on hydrological and hydraulical analysis on the system of Polder Grogol, West Jakarta. The estimation of design flood discharge employs Soil Conservation Service method with 5 years return period for Semeru and Makaliwe channels. The results of hydraulical analysis shows both channels are still adequate in draining design flood discharge. However, the existing pumping system is no longer sufficient to keep the reservoir’s water level below the bottom of reservoir’s inlet channel. There are several options to lower the reservoir water level. In this study, the approach is to add a new pump with the capacity of 0,25 m3/s wihout changing the formation of existing pumps. The analysis results reveals the additional pump manages to lower the reservoir water level below the targeted elevation.

Abstract

Pembangunan suatu SPBU memerlukan perencanaan saluran drainase baik bagi keperluan drainase dalam SPBU maupun untuk keperluan drainase lingkungan. Drainase lingkungan diperlukan sesuai dengan situasi dan kondisi lingkungan lokasi SPBU. Situasi dan kondisi lingkungan SPBU di jalan Siliwangi – Rangkasbitung, Provinsi Banten memerlukan perhatian dan disain saluran drainase lingkungan. Saluran drainase lingkungan diperlukan karena beberapa hal, diantaranya: 1. Permukaan tanah asli lokasi SPBU berada pada posisi lebih rendah dari posisi jalan raya sehingga air hujan akan mengalir ke arah lokasi SPBU; 2. Lokasi SPBU berada pada daerah turunan dari suatu ketinggian; 3. Daerah sekitar sudang berpenghuni. 4. Drainase jalan raya belum ada. Situasi dan kondisi ini menjadi perhatian pemilik SPBU. Disain drainase lingkungan memerlukan data hujan, kontur dan peta situasi utuk menghitung dimensi dan penempatan saluran drainase. Hasilnya akan berupa rencana saluran drainase lingkungan berupa dimensi dan arah buangan. Hasil juga akan berupa tulisan untuk di sampaikan pada seminar PKM atau masuk dalam jurnal Bhakti.

Abstract

Rapid urbanization in coastal regions experiencing severe land subsidence has significantly heightened urban flood vulnerability, necessitating high-precision polder drainage systems. This research aims to evaluate the effectiveness of polder mechanisms in mitigating flood risks while simultaneously assessing the geotechnical integrity of channel embankments during operational phases. Utilizing a quantitative design based on 1D/2D hydrodynamic simulations, this study leverages high-resolution 0.5-meter LiDAR topographic data from the Geospatial Information Agency (BIG), covering a 1,250-hectare catchment area in West Semarang. Official secondary data from the Ministry of Public Works and Housing (PUPR) regarding pump specifications and geotechnical parameters including cohesion and internal friction angles were integrated to simulate 10 to 50-year rainfall return periods and rapid drawdown conditions. The results demonstrate that the polder system curtails the average inundation extent by 73.51%, with high model reliability (). However, geotechnical analysis reveals that excessive water evacuation rates (0.85 m/hour) diminish the Factor of Safety (FS) to a critical level of 1.08, falling below the safety threshold of 1.25. These implications suggest that pump operational policies must be synchronized with soil stability limits to forestall structural failures. This study concludes that the integration of LiDAR data and geotechnical parameters is vital for the sustainability of polder infrastructure. Future research is encouraged to explore automated pumping systems controlled by pore water pressure sensors to optimize both safety and efficiency in urban drainage management.

Abstract

Rapid urbanization within priority watersheds has triggered severe hydrological imbalances, necessitating a data-driven evaluation of land-use transformation. This study investigates the correlation between built-up area expansion and runoff coefficients () within the Upper Citarum Watershed, Indonesia, between 2014 and 2024. Utilizing a longitudinal quantitative design, the research integrates secondary statistical data from the Central Bureau of Statistics (BPS) with multi-temporal Landsat 8-9 OLI/TIRS satellite imagery. Spanning approximately 177,115 hectares, the analysis focuses on sub-watersheds with settlement growth exceeding 5% annually. Land Use and Land Cover (LULC) classification was executed using the Random Forest algorithm, while weighted runoff coefficients () were calculated through the Rational Method. Results indicate a profound shift in hydrological response, with the  value escalating from 0.38 in 2014 to 0.59 by 2024, representing a 55% increase in peak discharge potential. Statistical validation reveals an exceptionally strong positive correlation () between BPS-documented building floor area growth and satellite-derived impervious surface expansion. These findings imply that current spatial planning and Building Permit (IMB) policies are insufficient to mitigate the loss of natural infiltration zones. The study concludes that the watershed has surpassed critical hydrological safety thresholds, necessitating a radical overhaul of Building Coverage Ratio (KDB) regulations and the mandatory adoption of Low Impact Development (LID) infrastructures. Future research should leverage high-resolution real-time sensors and artificial intelligence to enhance the precision of adaptive watershed management strategies.
