Abstract

 Located in the downstream watershed, Manado city is at risk of hydrometeorological disasters such as flooding every year, especially in conjunction with high tides. One solution to the city's flooding problem is to provide flood water storage by building the Sawangan dry dam in North Minahasa Regency. In building a dam, dam safety is a very important requirement to minimize disaster risks for the community such as property losses and damage to infrastructure downstream of the dam. Dam safety is highly dependent on the accuracy of planning and during construction. The safety of a dam also depends on the operation stage, the implementation of maintenance, as well as intensive and continuous supervision, monitoring the behavior of the dam and its building facilities. The purpose of the geotechnical instrumentation analysis study of Sawangan Dam in North Minahasa Regency is to determine the ideal geotechnical instrumentation needs in the process of optimal and periodic observation of dam behavior. Geotechnical parameters affect dam behavior due to soil strength related to pore water pressure, water seepage, deformation characteristics of foundation and embankment materials during construction and after construction. Determination of the amount of geotechnical instrumentation installed at Sawangan Dam is based on technical data of the dam dimensions. Based on the analysis conducted, the required geotechnical instrumentation components are; pore water pressure gauges, dam deformation gauges installed inside and outside the embankment, groundwater level gauges, seepage gauges, reservoir water level gauges, and other supporting components. By installing geotechnical instrumentation using telemetry systems or integrated computer systems, data acquisition, management and security are easier.

Abstract

As the population increases, the water demand is also increasing. The river flow is the dominant water source to fulfill the needs of human life, so the river should always be kept sustainable, the way to keep is by trying the cross-sectional capacity of the river stable from sediment deposits. Indulung River is one of the rivers in Tarakan City which is experiencing siltation due to sedimentation. Total sediment analysis was conducted to obtain the value of sediment transport and to obtain a method that can be used as a benchmark in determining the total sediment discharge in the Indulung River, using the Yang method and Bagnold method. From the research results, the average sediment discharge using the Yang method is 4.34 tons/year and Bagnold's method is 2.01 tons/year. Based on the recapitulation, which produces the largest value is the Yang method, with a value of 4.34 tons/year, the Yang method is used as a benchmark for other sediment transport methods.

Abstract

Ngasem District, Kediri Regency is an area that is close to educational centers, shopping centers, and tourism areas, so it is suitable to build housing in the area. However, there were several residents' houses that were damaged, such as cracked floors and walls. One of the contributing factors is the condition of the soil. This study aims to conduct a soil investigation to determine the characteristics of the soil in the area by using laboratory tests including sieving gradation tests, atterberg limits, compaction and soil shear strength and the results show that the soil in the area is classified as SW-SC soil, namely well graded sand with a little clay mixture so it has low plasticity. In addition, the maximum dry unit weight was 1.76 gr/cm3, the optimum moisture content was 15.38% from the compaction test and the cohesion value was 0.894 kPa and the shear angle was 29.685° from the shear strength test. The results of this study can be useful in providing an overview of soil characteristics as a reference in construction projects.Keywords: soil characteristics, SW-SC soil, atterberg boundaries, Ngasem District

Abstract

The flow that has a free surface is a form of water flow in an open channel. However, the flow of water in open channels is not always the same, due to topographic differences along the channel. This results in a difference in the value of the flow velocity and the value of the discharge. Therefore, it is necessary to conduct a study on discharge on flow velocity and wet cross-sectional area in different types of channels. The type of channel used in this study is a turning channel and a non-uniform channel, both of which are located in the Yogyakarta Mataram Channel. The data used is secondary data obtained from previous research in the form of channel cross-section data and flow velocity in each channel. The results of the analysis show that the discharge in both types of channels has the same curve pattern as the average flow velocity curve. Then the suitability of the two curve patterns is influenced by the value of the wet cross-sectional area, where the greater the value of the wet cross-sectional area, the greater the value of the discharge, and vice versa.Aliran yang memiliki permukaan bebas merupakan salah satu bentuk aliran air pada saluran terbuka. Meskipun demikian aliran air pada saluran terbuka tidaklah selalu sama, karena adanya perbedaan topografi di sepanjang saluran. Hal tersebut mengakibatkan adanya perbedaan nilai kecepatan aliran dan nilai debit aliran. Oleh karenanya perlu dilakukan suatu penelitian mengenai debit aliran terhadap kecepatan aliran dan luas penampang basah pada jenis saluran yang berbeda. Jenis saluran yang digunakan pada penelitian ini yaitu saluran berbelok dan saluran aliran tidak seragam, yang mana kedua jenis saluran tersebut berlokasi di Saluran Mataram Yogyakarta. Adapun data yang digunakan adalah data sekunder yang diperoleh dari penelitian sebelumnya berupa data penampang saluran dan kecepatan aliran di masing-masing saluran. Hasil analisis yang didapat bahwa nilai debit aliran di kedua jenis saluran tersebut memiliki pola kurva yang sama dengan pola kurva kecepatan aliran reratanya. Kemudian sesuai atau tidaknya kedua pola kurva tersebut dipengaruhi oleh besarnya nilai luas penampang basahnya, yang mana semakin besar nilai luas penampang basah maka semakin besar nilai debit alirannya, begitu pula sebaliknya.

Abstract

The beach is an area on the edge of the sea which experiences the influence of sea water fluctuations. Between the coast and the mainland separated by an imaginary line called the coastline. One of the problems on the coast is the decline of the coastline (Abrasion) and the progress of the costline (Accretion). Beaches that must be protected from the phenomenon of Abrasion and Accretion needs to be identified first to find out how far the changes have occurred in the coastline. The beach which is the object of this study is the beach on the north side of Tarakan Island. Identification was carried out by applying the DSAS Method (Digital Shoreline Analysis System) with change analysis using the LRR Method (Linear Regression Rate) and RMSE Method (Root Mean Square Error) while the mold delineation coastline based on Landsat satellite imagery in 1988, 1990, 2010, 2016, 2022, and 2023. The results of studies conducted in this study indicate that there has been a decline in the coastline with an average rate of change of 2,16 Meter/year and is predicted to increase backward an average of 0,74 Meter/year in 2033 for sandy beach areas. While in other areas there is progress of the coastline which is estimated to have a rate increase of an average of 2,40 Meter/year for Mangrove vegetation areas and an average of 0,19 Meter/year for community residential areas in 2033.

Abstract

IPA Kampung Bugis service area includes West Tarakan Sub-district and Central Tarakan Sub-district. These two sub-districts are the ones with the highest population density in the city of Tarakan, so in terms of water supply, it is necessary to carefully consider to avoid water deficits if there is no rainfall in Tarakan. This study aims to calculate the water balance of the Karang Anyar River as the raw water source for the IPA Kampung Bugis. The method used for availability calculations is the NRECA method. From the analysis of the reliable discharge Q90 of the Karang Anyar River using the NRECA method, an average Q90 reliable discharge of 55 liters/second is obtained, while based on the analysis of water needs in 2031, it is 295,852 liters/second. These results indicate that the Karang Anyar River is unable to meet the water needs in the IPA Kampung Bugis service area in the city of Tarakan

Abstract

Indonesia merupakan negara yang berada di zona tektonik aktif yang menyebabkan kerentanan terhadap gempa. Pembangunan infrastruktur di Indonesia harus direncanakan terhadap beban gempa dan fenomena dari gempa. Likuefaksi merupakan fenomena yang terjadi akibat gempa dengan kondisi tanah pasir lepas hingga sedang, butir halus kurang 35% dan muka air yang dangkal. Bahaya potensi likuefkasi dianalisis dengan metode simplified procedure dan liquefaction potential index (LPI). Analisis potensi likuefaksi juga dilakukan secara numeris dengan program Midas Gts Nx dengan model tanah UBC Sand. Secara numeris likuefaksi dapat dievaluasi dengan melihat nilai pore pressure ratio (PPR). Hasil analisis secara analitis didapatkan potensi likuefaksi terjadi dari pada tanah pasir lepas dan pasir sedang, dengan tingkat potensi likufaksi tinggi dan sangat tinggi. Analisis secara numeris didapatkan terdapat likuefaksi pada lapisan pasir lepas dan pasir sedang apabila terjadi gempa dengan percepatan maksimal 0,356g dan likuefaksi hanya terjadi pada lapisan pasir lepas apabila terjadi gempa dengan percepatan maksimal 0,275g.
