Abstract

Sungai Pedolo merupakan sungai utama yang melintasi Kota Bima. Sungai ini memiliki luas daerah aliran sungai seluas 216,11 km2 dimana setiap musim hujan menimbulkan banjir di setiap pengalirannya terutama di Kota Bima. Hal ini mengakibatkan lumpuhnya aktivitas pemerintahan, perekonomian, dan jalur transportasi menuju Kota Bima. Oleh sebab itu perlu dilakukan pembuatan Saluran Pengelak L=1.338 m, dengan kapasitas debit 50 m3/dt. Pengendalian Banjir Sungai Pedolo dengan Saluran Pengelak, bertujuan untuk mengurangi debit banjir pada Sungai Pedolo. Dari perhitungan banjir Sungai Pedolo dengan Q5 tahunan = 233,294 m3/dt, jika direduksi dengan Q pengelak = 50 m3/dt, maka debit banjir dihilir Sungai  Pedolo menjadi 183,294 m3/dt. Dengan menggunakan Software Hec Ras terlihat bahwa dengan rencana saluran pengelak dapat mengurangi debit banjir di daerah hilir di Kota Bima, yang dampaknya bisa mengurangi Kota Bima yang tergenang dari banjir sekitar 69,55 % (185 ha), dimana sebelum adanya rencana saluran pengelak yang  tergenang banjir seluas 266 ha.

Abstract

The background of the problem is that the need for water for various purposes constantly increases in line with the population growth and changes in water use patterns caused by technological advances, industrial growth, and changes in land use. Moreover, from the existing problems, several problem formulations were obtained as the basis for identifying the presumption of groundwater presence, among others, 1). what is the magnitude of the infiltration rate in the study area in relation to the influence of land use conditions, 2). how the results of geo-electric interpretation using the Schlumberger configuration in estimating aquifer layers based on geo-hydrological aspects, and 3). how the effect of time and cost efficiency. Based on the results of the analysis and calculations, several things can be concluded, including: 1). the volume of the infiltration rate using the Horton method (q) by considering the land cover / land use conditions (C), it is known that the average infiltration capacity on the land in the study location per year is more than 200 cm / year, and has an effective enough infiltration capacity so that it is average. -the annual average can store water up to> 200 cm / year, 2). In that area, an aquifer layer was found at a depth of 30-50 meters at the GL 1 point, and the GL point at a depth of 22-55 meters, with the results of the analysis showing the ability of the land to carry out the infiltration process properly and validated from the results of geo-electric investigations, and 3). the results evaluation analysis is able to streamline the amount of operational costs for groundwater source investigations and the time of implementation

Abstract

Panorama Residence housing which has an area of 8000 m2 is located in a plain area with a slope of about 0-1%. The survey results on the Panorama Residence Housing, Cemengkalang Village, Sidoarjo District, have an elevation of -0.20 m, slightly above the flood level – 0.30 m. This area has a high probability of flooding due to overflow from the Pucang River, which runs off (run-off water) from other areas if it rains with high intensity. Moreover, the Panorama Residence area is a dense residential area with roads and parking lots, so rainwater has a smaller chance of infiltrating and running off. After analysis, The flood discharge at the 25-year return period on the Pucang River was 72,561 m3/sec. At the same time, the cross-sectional capacity of the Pucang River was 64,402 m3/sec, so the cross-section of the Pucang River at the Panorama Residence Housing location experienced overflow. The run-off volume is 102.6 m3, while the total capacity is 565.68 m3, so the extended storage capacity is quite adequate. In rainy conditions, t = 30 minutes, the run-off volume that occurs = 30.96 m3, and the total channel length = 493.12 m, the total drainage channel capacity = 184.92 m3 is greater than the run-off volume, 30.96 m3.

Abstract

A total of 5,354 MBR individuals have applied to reside in Rusunawa and have remained on the waiting list until 2022. This has prompted the Surabaya City Government to provide Rusunawa, with one of them located in Tambak Wedi Village, Kenjeran District, Surabaya City. The objective of this research is to assess the viability of investing in the construction of Rusunawa Tambak Wedi from technical, market, and financial perspectives. The research methodology combines quantitative and qualitative approaches, utilizing primary and secondary data obtained previously. The technical feasibility analysis indicates that the construction of Rusunawa is deemed feasible, as it falls under the government's responsibility to address the housing needs of MBR individuals. The analysis considers factors such as the KDB space utilization intensity of 50%, KLB of 8 points, maximum building height of 100 meters, and KDH of > 10%. Furthermore, the market feasibility analysis reveals that 77.7% of the respondents, primarily from the MBR category, have expressed interest in residing in Rusunawa. Additionally, 69.9% of the respondents have stated their willingness to pay rent below Rp. 750,000 per month. Lastly, the financial feasibility analysis demonstrates that the Medium Rate Structure 1, Lower Rate Structure 1, and Lower Rate Structure 2 are considered feasible based on the NPV, IRR, BCR, and PP methods. However, the Medium Rate Structure 2 and Upper Rate Structure are deemed unfeasible.

Abstract

Kediri is the third largest city in East Java after Surabaya and Malang with a population growth of 289,418 people in 2023. The International Airport will open at the end of 2023 in Kediri. However, rapid population growth has also led to an increase in mobility and the number of motorized vehicles on the streets of Kediri City, including at the research site in Dhoho Plaza. The analysis of the signaled intersection was carried out using the MKJI 1997 method, and Visual PTV Vissim for three days on Monday, Friday, and Sunday. Based on the results of the analysis, a cycle time of 90.7 was obtained which affected saturation in each arm of the intersection. There is a potential reduction in signal light waiting time from 135 seconds to 118 seconds by repairing side obstacles. The solution to overcome side obstacles is to improve facilities such as traffic lights and adjust the timing of signal lights. The change in the value of side barriers also has a significant impact on waiting times, queues, and fuel costs at the intersection of Pasar Pahing, with congestion cost efficiency reaching Rp. 22,679,183 in the next 5 years.

Abstract

Watu Ulo Beach serves as a vital hub for fishing communities, supplying resources for sea fishing and serving as a landing point for catches. The local government plans to construct a fishing port at Watu Ulo to enhance facilities for fishermen. This study assesses the financial feasibility and sensitivity of investing in the port's construction, considering three income scenarios: pessimistic, moderate, and optimistic. Financial analysis using NPV, IRR, BCR, and PP methods deems the project feasible for moderate and optimistic scenarios, but not for the pessimistic scenario due to IRR (6.15%) < MARR (7.72%). Sensitivity analysis reveals that revenue sensitivity is critical for all scenarios, with the investment becoming unfeasible if revenue falls below certain thresholds: -13.67% for pessimistic, -39.96% for moderate, and -40.75% for optimistic scenarios. Operating cost sensitivity is also crucial, rendering the investment unfeasible if costs deviate beyond specific thresholds: -15.96% for pessimistic, +22.67% for moderate, and 25.59% for optimistic scenarios.

Abstract

Jabung District is a sub-district located in the Malang Regency area of 135.89 km2 or around 4.56 percent of the total area of Malang Regency. This sub-district consists of 15 villages, including Argosari, Gadingkembar, Gunungjati, Jabung, Kemantren, Kemiri, Kenongo, Ngadirejo, Pandansari Lor, Sidomulyo, Sidorejo, Slamparejo, Sukolilo, Sukopuro, and Taji. With a population of 74,311 people in 2020, with a population density of 592 people/km2. In Jabung District, especially in 4 villages, including Pandansari Lor Village, Gading Kembar Village, Argosari Village, and Kemiri Village, there is currently a water shortage. Siuk Source Potential has water potential large enough to meet the standard needs in these 4 villages by gravity. From the results of instantaneous discharge measurements during the dry season in 2021, it can be seen that the discharge in Sumber Siuk is 65 l/sec, and the planned collection to fulfill these 4 villages is 20 l/sec. Construction of the broncaptering and raw water distribution network was built in 3 stages. Before the physical implementation of the installation of distribution pipes in stage 3, a trial run was carried out from stage 1 and stage 2.
