Abstract

Belmera toll road in North Sumatra was the first toll road, links Belawan-Medan-Tanjung Morawa. The aim of this research is to find the relationship model between speed, density and volume on Belmera toll road based on a traffic study. The traffic study which embodies volume study and the speed of vehicles were divided into 5 vehicle classification, into 2 traffic lines (Entrance and Exit Tanjung Morawa’s toll gates), was conducted on Friday and Saturday around the peak hour on each traffic current. The study concluded that Greenberg model is the best approach for traffic current on Belmera toll road. According to Greenberg model we acquire a mathematical equation of the relationship between speed-density, volume-density, and volume-speed of Exit Tanjung Morawa’s toll gates as: S=98,100-6,700LnD, V=98,100D–16,700DLnD, V=355,758Se-0,059S and the Entrance as: S=99,312–17,442LnD, V=99,312D–17,442DLnD, V=297,033 Se-0,057S. Based on the observation and application of Greenberg model, traffic indicator (v/c, flow, density) of both current revealed that the level of service of Belmera toll road is C and it’s a fine traffic performance so far. The speed rate (km/hour) and density (pcu/km) revealed that the acquired rate from the observation is smaller than the application of Greenberg model.

Abstract

Skid Resistance is the force generated between the pavement surface and vehicle’s tires to resist the vehicle advance motion when braking. In this research the correlation between skid resistance value and texture depth on the pavement surface will be determined. The skid resistance value determined by using the British Pendulum Tester (BPT) and to determine the texture depth used Sand Patch Method. The research is conducted directly on a macro textured surface with two methods. The first method is applied on Ngumban Surbakti Road where the samples tested with the same distance from the edge of the pavement along the road; The second method is applied on Jend. Sudirman Road where the samples tested with specific distances from the edge of the pavement until the median. From the results of the analysis, there are some conclusions: (1) there is a positive correlation between the texture depth and skid resistance with a coefficient of determination (R2) = 0.028 on Ngumban Surbakti Road and (R2) = 0.191 on  Jend. Sudirman Road;(2) the increase of skid resistance value is directly proportional to the increase of surface texture depth value; and (3) the different methods did not cause significant yield differences.

Abstract

Human daily activities can not be separated from clean water, ranging from bathing, washing, drinking and cooking. Groundwater is one of the sources of water used to obtain clean water. In coastal areas or river estuaries in developing countries, villagers generally have difficulty getting clean water. Jaring Halus Village is located in Secanggang district, Langkat regency, North Sumatra Province. The village is bordered by the ocean and mangrove forests, where transportation access is difficult and limited. This village has received clean water services from the PDAM government, but the water flowing into people's homes has been increasingly choked. Several drill wells have been provided by the government but can only be found at a distance of 100-200 m from the beach. This cause underlies the Community Service Program team choosing a location in The Village of Jaring Halus. This activity aims to obtain clean water. This activity aims to get the clean water needs of residents by making drill wells, providing water storage tanks and installing water faucet installations in designated locations. With this facility, all village communities can accommodate and utilise clean water for daily needs.

Abstract

Bahan aditif sebagai bahan yang ditambahkan pada campuran aspal bertujuan untuk meningkatkan mutu campuran aspal serta meningkatkan kekerasan dan kekuatan perkerasan jalan terutama yang sering dilalui kendaraan berat. Beberapa jenis bahan tambahan yang dapat dicampurkan ke dalam aspal antara lain kapur, plastik, dan karet. Penelitian ini bertujuan untuk mengetahui pengaruh penambahan silica fume terhadap karakteristik campuran Asphalt Concrete Wearing Course (AC-WC). Silica fume yang ditambahkan pada campuran aspal mempunyai variasi kadar 2%, 4%, 5%, 6%, dan 8% dari kadar aspal. Benda uji penelitian sebanyak 92 buah yang terdiri dari 36 benda uji Marshall Test sebelum Kadar Aspal Optimum (OAC), 54 benda uji Marshall Test setelah OAC dan 2 benda uji Wheel Tracking Machine (WTM) Test. Pada penelitian ini juga dilaksanakan pengujian ekstraksi Metode Refluks untuk membuktikan adanya kesesuaian antara gradasi agregat yang dipakai sebelum dan sesudah Marshall Test. Dari hasil Uji Marshall diketahui bahwa penambahan silica fume dengan kadar 5% pada campuran aspal menghasilkan karakteristik yang paling baik diantara tingkat variasi lainnya yang memenuhi Spesifikasi Bina Marga Revisi III tahun 2010. Dari hasil pengujian WTM dengan penambahan kadar silica fume sebesar 5% pada campuran aspal menunjukkan kecepatan deformasi total yang lebih rendah. Hal ini menunjukkan bahwa campuran aspal mempunyai ketahanan deformasi yang lebih tinggi dibandingkan tanpa penambahan silica fume.

Abstract

Saat ini akses jalan pada kawasan Pondok Tahfiz Kita Bina masih terbuat dari tanah. Akses jalan sangat rawan terutama saat kondisi cuaca hujan yang mengakibatkan jalan menjadi licin dan becek. Oleh karena itu diperlukan adanya penutup lapisan perkerasan permukaan tanah seperti permukaan jalan atau halaman. Pondok Tahfiz Kita Bina sendiri merupakan pondok tahfiz yang dibangun dengan mengandalkan bantuan dana dari donatur dan sumbangan dari masyarakat. Kegiatan Pengabdian Kepada Masyarakat Universitas Sumatera Utara ini bertujuan untuk memberi solusi dari permasalahan tersebut. Tim pengabdian memberikan solusi berupa pembuatan akses jalan yang ekonomis. Metode kegiatan berupa pemberian pelatihan dalam pembuatan paving block serta pemasangannya sebagai penutup perkerasan permukaan tanah. Demi untuk menekan biaya dalam pembangunan akses jalan maka kegiatan ini memanfaatkan bahan dasar material berupa pasir yang dapat diambil dari sungai yang berada tidak jauh dari lokasi pengabdian.Hasil yang diharapkan dari pelatihan ini ialah penghuni pondok tahfidz akan dapat secara mandiri menghasilkan sebuah produk berupa paving block yang dapat dimanfaatkan sebagi bahan pembuatan akses jalan. Kegiatan telah berjalan dengan lancar sehingga diharapkan dari kegiatan ini akan menambah keterampilan serta kemandirian dari para santri Tahfidz Kitabina serta memanfaatkan ilmu dan alat yang kami berikan agar bernilai ekonomis dan bernilai manfaat.
