Abstract

Perancangan pondasi tiang pancang memerlukan analisis yang rumit karena melibatkan banyak aspek dan parameter yang harus dipertimbangkan serta menggunakan persamaan-persamaan kompleks. Oleh karena itu, penggunaan perangkat lunak diperlukan untuk menyederhanakan analisis ini agar dapat menghasilkan hasil yang cepat dan akurat. Plaxis adalah salah satu program yang dapat digunakan untuk menganalisis desain pondasi tiang pancang. Perhitungan daya dukung dan penurunan pondasi dilakukan secara manual selama penelitian ini dan membandingkan hasilnya dengan pemodelan menggunakan Software Plaxis. Hasil penelitian menunjukkan bahwa dimensi pondasi tiang pancang yang aman adalah diameter 60 cm dengan kedalaman 43 m, menggunakan beton berkualitas 30 MPa. Penulangan yang digunakan adalah tulangan pokok 4 ∅19 dan tulangan spiral ∅10 − 150. Hasil rata-rata perhitungan daya dukung tiang tunggal secara manual adalah 804,382 ton, sementara hasil dari Plaxis 2D adalah 656,494 ton, dengan perbedaan 18%. Untuk perhitungan daya dukung kelompok tiang secara manual, rata-rata adalah 779,946 ton, dan dari Plaxis 2D adalah 1528,625 ton, dengan perbedaan 49%. Hasil perhitungan penurunan tiang tunggal secara manual rata-rata adalah 0,0457 m, sedangkan dari Plaxis 2D adalah 0,0391 m, dengan perbedaan 14%. Untuk kelompok tiang, perhitungan penurunan manual rata-rata adalah 0,0332 m, dan dari Plaxis 2D adalah 0,0371 m, dengan perbedaan 12%. Perbedaan hasil antara kedua metode ini kemungkinan disebabkan oleh perbedaan parameter yang digunakan, di mana parameter pada Plaxis 2D lebih kompleks dibandingkan dengan analisis manual.Kata Kunci : Pondasi, Daya Dukung, Plaxis

Abstract

The community, both individuals and groups, need water for daily and other needs. From the various types of needs, the water for drinking water is a top priority, above all other necessities.Excessive exploitation of groundwater that exceeds the ability of aquifers to provide groundwater due to competition for various interests can cause a continuous decline in groundwater level and will certainly reduce the potential for groundwater availability in the aquifer. In this research, the potential of groundwater in Jeneponto’s aquifers in several locations is examined using in situ pumping test. From the pumping test results, it is known that the potential of groundwater reserve in Jeneponto Regency is quite significant and is spread in several districts with a minimum discharge supply of 4 litres per second. However, some procedures must be taken to protect the availability of groundwater in the regency from the technical aspects for example the determination of pumping location, the depth of groundwater pumping and the maximum pumping discharge allowed, and also all steps that support groundwater recharge.

Abstract

Cabenge River is part of the WalanaeCenranae River area in Soppeng Regency. Annually, the area around the Cabenge River gets the most losses from floods, both in terms of facilities and infrastructures. This study aims to map the areas prone to flood and flood risk, based on the field that gets the most significant impact. This study uses a Geographic Information System (GIS) as a tool and ArcGis Software in determining the level of vulnerability and risk of flooding at the study site. This type of research is a combination of mapping (topographic results) and map analysis. The variables used are DEM (Digital Elevation Model) data and flood volume. The data processing technique used is the GIS-based inundation model approach using inundation height (H) based on a comparison between the volume of water (V) in inundated areas and the volume of water (Q) of flood sources. The results showed that Lilirilau District was in the high hazard class with an area of 100 km2 and had the biggest impact, while in Liliriaja District, the area that was in a high hazard class was 34 km2 and Ganra District was 21 km2.

Abstract

In big cities, communities generally consume clean water from local water supply company which uses surface water sources. However, due to the limitations of the company in supplying water, particularly in the dry season, an alternative is required, such as using groundwater without causing over-exploitation. This study aims to determine the optimal rate of groundwater pumping in the coastal aquifer to avoid seawater up coning using SEAWAT V.4 numerical model. The research method was carried out using a GEO-7X GPS device to obtain coordinate's location, land elevation and observation well distance from the coastline. Secondary data in the form of aquifer thickness data and geological map of the site were obtained from previous studies. The salinity test results show that the average salinity value of the ten water samples from observation wells is 36.8 mg/l, which means that the water is categorized as non-saline water (freshwater). These data are in line with the groundwater utilization monitoring activity report of Makassar City Environment Office in 2018, which reported that Ujung Tanah and Wajo Districts were found to be free from seawater intrusion. Even so, the potential for seawater intrusion is still considered high because of the location of community groundwater wells are near from the coast. One of the efforts to prevent seawater up coning is by limiting groundwater pumping. From the numerical modeling results, it is found that the maximum groundwater discharge in the research site, namely P3 is 20% of total flow rate(0.3 m3/day), P5 is 20% (1.32 m3/day), P6 is 40% (0.52 m3/day) and P10 is 20%(0.63 m3/day).

Abstract

PT. Vale Indonesia plans to mine at the Petea location using the open pit method. If viewed from the watershed boundary, the planned mining location is located in the upstream part of the Lamunto watershed. In connection with the existence of the mining plan, a solution is required to prevent things that can harm and damage the surrounding environment prior to implementation, especially related to soil erosion which is expected to impact the Lamunto watershed which is the outlet of the planned mining location. The method used in this study is to analyse the potential for erosion that occurs using the USLE (Universal Soil Loss Equation) method with the help of the ArcGIS application. Furthermore, the calculation of the sedimentation rate is carried out using the SDR (Sediment Delivery Ratio) equation based on the calculated erosion rate and the area of the mining plan that will be used to plan the sump (sediment storage tank). The results showed that the total sediment potential in sumps A, B, C, D, E, F, G, and H was 550.39 m3/year, 1195.31 m3/year, 1588.43 m3/year, 1908, 27 m3/year, 2423.33 m3/year, 1899.53 m3/year, 1941.76 m3/year, 2169.15 m3/year and 2756.29 m3/year, respectively. From these results it can be seen that the slope factor (LS) is more influential than the catchment area in calculating the sediment potential as evidenced by the total sediment potential in sump D which is greater than sump F.

Abstract

The Tamangapa landfill, the only operational landfill in Makassar City since 1995, is the subject of this study. The objective is to determine the direction of leachate flow generated by the waste in the Tamangapa landfill and simulate remediation management for the dispersed leachate, which has contaminated the groundwater flowing into community wells. Modflow + MT3DMS software was employed to model the groundwater flow direction, leachate dispersion, and pumping simulations. The concentrations of interest in this research were iron (Fe) and manganese (Mn). The modeling results revealed that the leachate from the Tamangapa landfill spreads from northwest to southeast, following the groundwater flow direction, and contaminates the community wells. Subsequently, a remediation management plan was developed using modeling techniques, specifically through pumping simulations with a pumping rate of 1500 m3/day. This pumping process was conducted until all the contaminated leachate in the community wells was removed, which was estimated to require a pumping duration of 15 months.
