Abstract

ABSTRACT: As a result of the closure of the U-Turn, the people around Jalan HR. Soebrantas complained because the travel time they took was very long and there was a buildup of vehicles at the U-Turn intersection of Jalan Manggis. The problem in this study is how is the condition of the U-Turn in front of the handsome Nurul Huda Mosque today . and how to overcome the U-Turn delay in front of the Nurul Huda Mosque . The method used in this study is analysis of existing traffic performance, analysis of traffic performance, applying 3 alternatives , proposing alternative problem solving, alternative problem solving based on the results of HR Road Performance Comparison. Soebrantas, it is obtained that the average degree of road saturation is 0.80, and the service level is D: The flow is approaching unstable, the speed is still tolerable. Alternative 2, the solution to the problem for this research, namely by widening the road in front of the shops This plan affects traffic performance to run smoothly as happened on the Purwodadi road section, but this is still hampered due to land acquisition if it is carried out along the HR road. Soebrantas. Alternative 3, using vissim simulation for U-Turn closure This plan is the final plan, but if this plan is carried out, you must plan for a Fly Over at the Tobek Godang red light intersectionKeywords: Alternative , U-Turn, Road performance

ABSTRACT: Geopolymer concrete uses pozzolanic materials such us fly ash to replace the role of cement. This study aims to design a geopolymer concrete mixture to obtain a compressive strength value based on the age or variation of the concrete mix and identify the effect of variations in alkaline activator solution on the compressive strength of geopolymer concrete. Fly ash which reacts with alkaline activator liquid in a ratio of 50:50, funcitions as a binder, where the alkaline activator used in this study is Na2Si03, and NaOH concentration of 10M with the test variable used is variation one at a ratio of 50:50; variation two at a ratio of 60:40 and variation three at a ratio of 66,67:33,33, while the filler composition and binder were 75:25. In this research, 27 samples were made of cylindrical specimens by testing the compressive strength of concrete at the age of 7, 21 and 28 days. The mixing method used in this research was the wet mixing method. Based on the research result, the average compressive strength at seven days for each variation was 11,533 Mpa; 9,300 Mpa and 12,367 Mpa. At 21 days each variation in a row was 9,300 Mpa; 11,567 Mpa and 14,800 Mpa. Each variation’s concrete with 28 days of age successively was 10,500 Mpa; 14,400 Mpa and 12,533 Mpa. In addition, the variation in the alkaline activator solution between Na2Si03, and NaOH affects the results of the compressive strength of geopolymer concrete. Keywords: alkaline activator, geopolymer concrete, fly ash, compressive strength ABSTRAK: Beton geopolimer merupakan beton yang menggunakan bahan pozzolan seperti fly ash untuk menggantikan peran semen.

Abstract

Universitas Borneo Tarakan berencana membuka program studi kedokteran pada tahun 2023. Sehingga, diperlukan sebuah gedung yang mampu mendukung berjalannya segala aktivitas perkuliahan. Struktur gedung diharapkan mampu menahan beban gravitasi dan gempa, sehingga setiap komponennya harus direncanakan memiliki daktilitas yang tinggi. Salah satu komponen penting dalam perencanaan gedung struktur beton bertulang tahan gempa khususnya yang menggunakan sistem rangka pemikul momen khusus (SRPMK) yaitu balok. Balok harus didesain dengan menggunakan standar terbaru yaitu SNI 2847-2019. Desain balok seluruhnya menggunakan mutu beton K-300 dan menggunakan baja tulangan mutu BJTS-420 untuk longitudinal dan BJTS-280 untuk sengkang. Hasil desain diperoleh pada balok induk tulangan longitudinal menggunakan diameter 19 mm (Ulir) dan tulangan geser terdiri 4 kaki dengan diameter 10 mm (Ulir). Sedangkan, pada elemen balok anak tulangan longitudinal mengunakan diameter 19 mm dan tulangan geser terdiri dari 2 kaki dengan diameter 10 mm.

Abstract

Landslides are events due to changes in land use in the classification marbles steep. The slope of the land can be identified by extracting elevation data from the earth’s surface. One way of measurement is to apply the photogrammetric method. In this research, a study was conducted on landslide-prone areas in the residential area of the Kampung Bugis Tarakan City, with a base map that was the results of processing UAV aerial photographs. The results of the study state that the photogrammetric method of aerial photographs of UAVs is able to provide an accuracy rate of 98%, and is able to provide an overview of landslide prone maps with an accuracy of 90%. From the application of this method, it was stated that the research location was a landslide-prone area with a high potential vulnerability level of 43,61% and 36,33% very high, which were spread over hillside areas in an area of 72,70 hectare.

Abstract

Raw water in Embung Bolong, Nunukan Regency, is currently experiencing a decline or depreciation due to low rainfall in Nunukan Regency, so it is necessary to conduct research on the availability of raw water, including the use of environmental conditions in Embung Bolong. Calculation of evapotranspiration using the Penman Modification and Effective Discharge method using the NRECA method includes data from related agencies in the form of rainfall data, air humidity, air temperature, wind speed, and length of sunlight. Based on the results of the analysis, the total water requirement for 2031 is 4.229 lt/s for the West Nunukan Village zone, 22.633 lt/s for the Central Nunukan Urban Village zone, 20.228 lt/s for the East Nunukan Urban Village zone, 6.475 lt/s for the South Nunukan Urban Village zone , 6,304 lt/s for the Selisun Village zone and the mainstay discharge Q90 reviewed from the last 10 years from 2012 to 2021, the largest water availability occurs in June, which is 50,645 lt/s and the smallest water availability occurs in April, namely of 0.224 l/sec.

Abstract

ABSTRACT: This study aims to assess the condition of the road pavement using the Bina Marga method. The condition of the road pavement examined includes the type and level of damage so that the value of the condition of the road pavement and alternatives for handling the road damage can be identified. The research location is the Kenanga road section which is a secondary collector road located in a densely populated residential area in Karang Anyar Village, Tarakan City, which functions as an alternative axis road connecting the West Tarakan District and Central Tarakan District, North Kalimantan Province. This Bina Marga method examines the volume of traffic and the type of damage that occurs on the road pavement. The results of the road pavement condition assessment are then used as a reference and selection of alternative road damage repairs. The results showed that the road damage found on the Kenanga road section was potholes, depression, patching end utility cut patching, and polished aggregate, then the results of the analysis used the Bina Marga method. a score of 10 is obtained for the right side and a value of 11 for the left side which means that the road section needs to be repaired in the drainage system component by including it in the periodic maintenance program. Keywords: Bina Marga Method, Road Damage, Road Handling Method ABSTRAK: Penelitian ini bertujuan menilai kondisi perkerasan jalan menggunakan metode Bina Marga. Kondisi perkerasan jalan yang diperiksa meliputi jenis dan tingkat kerusakan sehingga dapat diketahui nilai kondisi perkerasan jalan dan alternatif penanganan kerusakan jalan tersebut. Lokasi penelitian dilakukan pada ruas jalan Kenanga yang merupakan jalan kolekter sekunder yang berada pada kawasan permukiman padat penduduk di Kelurahan Karang Anyar Kota Tarakan, berfungsi sebagai jalan poros alternatif menghubungkan wilayah Kecamatan Tarakan Barat dan Kecamatan Tarakan Tengah Provinsi Kalimantan Utara. Metode Bina Marga ini meninjau volume lalu lintas serta jenis kerusakan yang terjadi pada perkerasan jalan. Hasil penilaian kondisi perkerasan jalan selanjutnya digunakan sebagai acuan dan pemilihan alternatif perbaikan kerusakan jalan tersebut. Hasil penelitian menunjukkan kerusakan jalan yang ditemukan  pada ruas jalan Kenanga adalah kerusakan lubang (potholes), kerusakan amblas (Depression), kerusakan tambalan (Patching end Utility Cut Patching), dan kerusakan pengausan agregat (polised agregat), selanjutnya hasil analisa dengan metode Bina Marga diperoleh nilai 10 untuk sisi kanan dan nilai 11 untuk sisi kiri yang berarti bahwa ruas jalan tersebut perlu dilakukan perbaikan-perbaikan pada komponen sistim drainase dengan memasukan kedalam program pemeliharaan berkala.  Kata kunci: Metode Bina Marga, Kerusakan Jalan, Penanganan Kerusakan Jalan
