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

 In recent years, the increasing amount of plastic waste in many cities in developing countries, including Kupang City, has become a serious environmental problem. The use of plastic waste as a pavement material is one solution to deal with the problem of plastic waste. One type of plastic that can be used as an asphalt mixture modification material is Low Density Polyethylene (LDPE). This research aims to determine the use of LDPE plastic waste modified with AC-WC (Asphalt Concrete-Wearing Course). Five variations of AC-WC mixture were made based on LDPE plastic waste content of 6, 7, 8, 9, 10% based on optimum bitumen content (OBC). Marshall test method was used to determine the OBC and to evaluate the marshall characteristics of LDPE modified AC-WC. The OBC of conventional AC-WC was found to be 5.23% by weight of total aggregate while the ptimum plastic modified bitumen content (OPMBC) of LDPE modified AC-WC was 7.45% by weight of OBC. AC-WC modified with 7.45% LDPE waste had 47.98% higher OPMBC compared to conventional AC-WC

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

Road infrastructure has an impact on the occurrence of road traffic accidents. The geometry of a road is a variable that influences the occurrence of road traffic accidents. Interpreting the observed crashes into an equation that can describe the crashes is one of the most difficult problems faced by scientists and engineers in any research. The traffic accident research conducted is still limited to analyzing the causes of accidents and jumping to handling strategies that do not reveal how much geometric influence on accidents at the location. This research was developed using a comprehensive modeling approach to illustrate how highway geometric design, in this case the alignment, influences crash rates. This study aims to analyze the influence of road geometrics on the incidence of accidents. The method used is multiple liner regression measurement model using R-Studio. The variables to be studied include road geometry planning parameters, especially horizontal alignments which include stopping sight distance (X1), radius of horizontal curve (X2), shoulder width X3, and transition curve length (X4). The results of the study obtained a relationship in the mathematical equation Y = 99.55508-0.02634X1+1.17647X2-0.06999X3-0.03906X4 with the most significant correlation value produced is the transition curve length and radius of horizontal curve. Based on the multiple R-squareed value of 0.8775 this model has a very strong correlation category. Where the ability of X1 to X4 is able to explain Y by 80%.

Abstract

Beton merupakan bahan bangunan populer yang diakui kekuatan dan daya tahannya. Para peneliti telah mengeksplorasi penggunaan superplasticizer dan gel C-S-H untuk meningkatkan kualitas beton . Superplasticizer adalah bahan tambahan kimia yang dapat ditambahkan ke campuran beton untuk meningkatkan fluiditas sekaligus menjaga kekuatan. Hal ini memudahkan pemasangan dan meningkatkan kemampuan kerja beton. Selain itu, menambahkan gel C-S-H ke beton dapat meningkatkan kinerja jangka panjang dan meminimalkan retak. Formasi gel C-S-H pada kekuatan dan daya tahan beton diselidiki secara cermat dalam studi ini dengan melakukan pengujian foto SEM EDS. Pemindaian Mikroskop Elektron-Spektroskopi Sinar-X Dispersi Energi adalah alat analisis yang kuat untuk menentukan komposisi unsur dan bentuk bahan berskala nano. Ini menyelidiki permukaan material dengan berkas elektron terfokus dan menghasilkan sinyal yang dapat digunakan untuk mengidentifikasi dan memetakan distribusi komponen yang ada. Hasil Uji SEM-EDS menunjukkan Unsur senyawa Ca, Al dan Si mendominasi. Rasio Oksida SiO2/CaO yang tinggi pada sampel cenderung memiliki kuat tekan yang lebih tinggi. Sebaliknya, material dengan rasio SiO2/CaO yang lebih rendah menunjukkan kuat tekan yang lebih rendah.

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.
