Abstract

Internal friction angle (φ) is one of the important parameter in a foundation engineering, especially in the stress distribution event. The higher value of the internal friction angle shows the higher of the material can withstand the lateral force. Cohesion factor (c) is also an integral part of the shear strength for the foundation material. In the granular soil such as sand or non-cohesive material, including aggregate, cohesion value usually assumed as zero, although some cohesion factor may be applied. In this research, two different materials were tested for their shear strength. The materials were Natural Crushed Aggregate (NCA) and Recycled Concrete Aggregate (RCA). Each material was also tested under two different circumstances. First, the materials were tested in a small-scale direct shear (SSDS) test with the maximum material size of 0.425 mm and 2.0 mm. Secondly, the materials were tested in a large-scale direct shear (LSDS) test with the graded size of aggregate according to road base layer specification. The SSDS showed the internal friction angle of NCA and RCA varies from 26.20 to 29.82 degrees. Whereas the LSDS showed the internal friction angle of NCA and RCA are 44.90 and 29.16 respectively. Both of SSDS and LSDS also showed the cohesion value of NCA and RCA.

Abstract

Abstract: Road damage is common occurrence at signalized intersections. This causes delays in vehicle mobility and leads to congestion. This research seeks to investigate the types of damage occurring at signalized intersections, the factors causing the damage, and the alternatives to prevent the damage. Based on RCI method the value is 4,4, it means that on the location, the condition of the road are bad, many holes, and irregular surface. And also in the  location often flooded, and affected by centrifugal force from the U turn, and the vibrating force while the vehicles waiting for the traffic light, and affected on the previous flexible layer get damaged. Based on that result, the repair possibility at the Traffic Light jalan Kaligawe KM. 4 (main road in front of Universitas Islam Sultan Agung) Semarang should use rigid pavement. And there are some specification items that relevant with the condition of the road: concrete slab thickness = 15cm, concrete slab length = 100m, shrink joint applied in space 5m, cross joint (dowel) applied with straight wire that have 32mm diameters, length 45cm, and space between the wire is 30cm, and tie bar use whorl beam that have 16mm diameters, length 70cm and space 75cm.

Abstract

Rob atau air pasang adalah banjir air laut atau naiknya permukaan air laut yang diakibatkan oleh air laut pasang yang menggenangi daratan. Lalu lintas yang padat dan rendaman air pasang di jalan utama mengakibatkan deformasi permanen yang membutuhkan aspal berkualitas yang tahan terhadap rendaman pasang surut dan beban lalu lintas. Penelitian ini bertujuan untuk mengetahui komposisi modifikasi job mix formula terbaik yang dapat digunakan untuk asphalt concrete wearing course. Penggunaan kombinasi LDPE dan aggregat slag menjadi pembaharuan yang belum ada sebelumnya. Limbah plastik Polyethylene (PE) memberi ketahanan terhadap air sehingga kombinasi tersebut dapat menjadi Job Mix Formula baru yang mampu tahan terhadap rendaman air pasang (rob) sehingga dapat digunakan dalam konstruksi struktur jalan (Flexibel Pavement) Asphalt concrete wearing course modifikasi direndam dalam air standar laboratorium, air rob, dan air dengan kandungan klorida (Cl- ) yang berbeda-beda. Durasi perendaman 7 hari, 14 hari dan 21 hari serta metode perendaman terdiri dari perendaman dengan pola menerus (continuous) dan perendaman dengan pola berkala/ siklik (intermittent). Komposisi terbaik untuk Asphalt Concrete Wearing Course yang didapat dalam perendaman menerus adalah agregat Slag 50% dan LDPE 6% sedangkan untuk perendaman berkala adalah agregat Slag 0% dan 50% dengan LDPE 6% dan 8%.

Abstract

Ketersediaan angkutan sekolah yang layak dapat menjadi alternatif solusi bagi pemangku kepentingan untuk merubah perilaku pelajar yang saat ini banyak menggunakan kendaraan pribadi dalam melakukan perjalanan kesekolah. Kondisi ini dinilai tidak efisien, mengingat dampak yang ditimbulkan. Jaminan ketepatan waktu, kenyamanan, keselamatan, dan keamanan dalam perjalanan menggunakan moda transportasi angkutan sekolah menjadi parameter hasil kajian efektivitas angkutan sekolah di Kota Tegal. Hingga saat ini, pelayanan angkutan umum di kota Tegal dinilai masih belum dapat bekerja secara optimal. Tidak optimalnya fungsi layanan angkutan umum di kota Tegal, dianggap menjadi salah satu penyebab tingginya tingkat penggunaan kendaraan pribadi dikalangan pelajar. Oleh karena itu, penyediaan jasa angkutan sekolah yang layak dapat menjadi salah satu solusi alternatif untuk mengatasi kepadatan arus lalulintas di kota tersebut, khususnya pada jam sibuk seperti jam berangkat dan pulang sekolah. Hasil penelitian ini juga menunjukkan bahwa minat pelajar dalam menggunakan jasa angkutan sekolah masih cukup tinggi, dengan catatan bahwa moda transportasi yang dimaksud mampu menjangkau daerah dimana para pelajar tinggal.

Abstract

Floods and Rob floods are natural disasters that often occur in Indonesia. The UNISSULA campus area is in the Pantura road area. UNISSULA is one of the campuses affected by floods and robs. Extreme weather conditions and rising sea levels have exacerbated the condition of the north coast road. Thus causing traffic jams and activities of the surrounding community to falter.The purpose of this study was to analyze the drainage system of the UNISSULA campus area by utilizing the potential of a storage pond by disposing of water directly into the estuary. With this research, it is hoped that it can be used as data and material for consideration for the development of a drainage system in the campus area and to become a pilot campus to control flooding. The method used is a simulation of the rainfall-runoff model using EPA SWMM Version 5.1.This study carried out two scenarios in carrying out flood control efforts, namely the first scenario, the existing west, and east retention ponds will be connected to pond 1, for the pond in the north, will be connected from pool 4 to the engineering pool, channeled to pool 3, to pool 2 and connected with pool 1 equipped with a pump with a capacity of 1 m3/sec with additional long storage from pool 2 to pool 1 along 184 meters. The second scenario is to break the direction of the front and rear drainage flows. For drainage, it will be pulled into pond 4, then a technical pond until it is connected to pool 2 and discharged directly into the sea with a flood pump with a capacity of 0.5 m3/sec. This makes the flood travel time short and is expected to reduce inundation. With this scenario, it can also be developed as Khairu Ummah Edu-tourism Khaira Ummah in the campus area.
