Abstract

Unsignalized intersections are a major point of concern due to the increasing number of vehicles. Bima City is a city located on the eastern part of Sumbawa Island, West Nusa Tenggara Province. As a developing city, congestion and busy traffic often occur on roads or intersections of Mongosidi and Anggrek roads. Therefore, this study was conducted to determine the performance and level of service of unsignalized intersections at Mongosidi Street and Anggrek Street. The method used refers to the Indonesian Road Capacity Manual (MKJI) 1997. This study aims to determine the indicators of traffic behavior at unsignalized intersections. The results of the calculation obtained a total flow of 3147 smp / hour, a capacity value (C) of 4234 smp / hour and a degree of saturation (DS) of 0.74, Traffic Delay (DT) of 8.07 sec / smp, intersection delay (D) of 11.73 sec / smp and upper and lower limit queuing opportunities of 44.46% and 17.74% respectively. This condition occurs on Monday, March 17, 2025 at the peak hour of 06.45-07.45 WITA. For the level of service of the intersection pattern, the conditions on Monday, March 17, 2025 at the peak hour of 06.45-07.45 WITA are also categorized as type C, namely stable flow, but the speed and movement of vehicles are controlled.Drivers are limited in choosing speed, with saturation density (Ds) around 0.45 - 0.74.

Abstract

The development and progress of science, especially in the field of building materials technology, has encouraged the birth of new concepts, especially for construction made of concrete. One of these new concepts is by presenting innovations in the manufacture of lightweight concrete to reduce the excessive use of bricks / concrete blocks as non-structural building materials such as walls. One way to overcome this is to use lightweight concrete as a precast wall or as a brick. Its use can reduce the magnitude of the load acting on the building and is fast in installation. The purpose of this research on lightweight concrete with a mixture of bamboo shavings is to determine the properties of the stacking material, the relationship between mechanical properties at the age of 14 and 28 days of concrete with no soaking conditions, and the effect of the addition of bamboo shavings. The tests and examinations carried out were compressive strength, strain, and content weight of lightweight concrete. The results showed that lightweight concrete with the most ideal bamboo shavings mixture was 1 cement: 1-1.5 bamboo shavings: 2 sand (fas value: 0.8) has a compressive strength of 1.65 MPa and 1.63 Mpa, respectively, for a content weight of 753.01 kg/m3 and 609.66 kg/m3.

Abstract

. Perancangan dan pemodelan struktur merupakan unsur yang esensial pada suatu bangunan agar dapat menghasilkan struktur yang kuat, stabil, dan awet. Pada dasarnya struktur adalah benda kontinum yang memiliki derajat kebebasan tak terhingga sehingga harus dinyatakan sebagai model derajat kebebasan banyak. Tujuan Penelitian ini dilakukan untuk menganalisis kinerja struktur Gedung 2 Universitas Muhammadiyah Bima. Metode yang digunakan yaitu dengan melakukan pendekatan secara analisis menggunakan pemodelan struktur yang meliputi pemilihan jenis struktur yang digunakan, penentuan material dan dimensi elemen struktur, sistem pembebanan pada struktur (beban mati, beban hidup, beban gempa dan lain-lain), analisis struktur, pengecekan kekuatan struktur. Hasil Analisis tegangan azial yang terjadi pada kolom sebesar -1475,761 kN, Gaya geser yang dihasilkan oleh balok dan kolom masing-masing sebesar 72,430 kN dan 62,080 kN. Momen lentur yang dihasilkan oleh balok dan kolom masing-masing sebesar 63.0184 kN-m dan 120,1879 kN-m. Momen torsi yang dihasilkan oleh balok sebesar 9,5972 kN-m. Lendutan yang terjadi pada balok dan sebesar 2,085599 mm lebih kecil dari L/360 batas yang diijinkan. Dari hasil perhitungan analisis struktur bahwa dimensi balok, kolom dan pelat layak digunakan untuk struktur konstruksi gedung.
