Abstract

This research aims to evaluate the online learning implementation activities at the UNIMED Faculty of Engineering to determine the various weaknesses and constraints. The research approach used is the CIPP model of Stufflebeam. And it focused on the content/material, facilities, processes, and outputs of online learning. Data were obtained from UNIMED Faculty of Engineering students through online questionnaires. The results showed that 1) the availability of learning resources is still low, as a content aspect, 2) network strength is weak at the input aspect, 3) the helpdesk service is lacking at the process aspect, and 4) the online effectiveness is low at the product aspect. On average, out of these four components, the lowest is online learning tools. In conclusion, this research found that learning facilities contributed to online learning effectiveness at the UNIMED Faculty of Engineering.

Abstract

Jalan raya merupakan infrastruktur dasar untuk menghubungkan lalu lintas dari satu tempat ke tempat lain. Di sekitar Jalan Willem Iskandar zona Medan Estate merupakan kawasan akademik dan industri, sehingga jumlah kendaraan yang melintas sangat tinggi pada jam sibuk. Volume dan berat beban kendaraan yang membebani jalan, seringkali mengalami kerusakan yang mengganggu di satu titik yang sama. Kerusakan jalan merupakan salah satu permasalahan hubungan antar kabupaten dan daerah. Sehingga perlu dilakukan analisis kerusakan Jalan Willem Iskandar. Penelitian ini menggunakan metode Bina Marga untuk mengevaluasi tingkat kerusakan Jalan Willem Iskandar khususnya di sekitar Universitas Negeri Medan. Jenis kerusakan jalan yang terjadi antara lain: pelepasan butiran, retakan aligator, retakan membujur, tambalan dan lubang. Berdasarkan nilai urutan prioritas kerusakan jalan, jenis penanganan jalan yang sesuai harus dimasukkan dalam program perbaikan. Kata Kunci: Analisis kerusakan jalan, metode Bina-Marga, Nilai urutan prioritas ABSTRACTThe highway is the basic infrastructure for connecting traffic from one place to another. Around Willem Iskandar Street at Medan Estate zone is an academic and industrial area, so the number of vehicles that pass is very high at peak hour. The volume and weight of the vehicle load that burdens the road, often suffers disturbing damage at the same point. Road damage is one of the problems for relations between districts and regions. So, it is necessary to analyze the damage to the Willem Iskandar Road. This study uses the Bina Marga method to evaluate the level of damage to the Willem Iskandar Road especially around the Universitas Negeri Medan. The types of road damage that occur include: granular release, alligator cracks, longitudinal cracks, patches and potholes. Based on the priority order value of the road damage, the appropriate types of handling that the road should be included in the improvement program Keywords: Bina-Marga method, Road damage analysis, Priority order value

Abstract

Utilization and management of Empty Fruit Bunches (EFB) fibre continue to develop as the main ingredient and additional material used in various industrial products. The technological breakthrough targeted in this study is the developed EFB fibre as a filler in polymer composite partition boards which are used as heat retainers in the interior construction of buildings. The partition board is a heat insulator, and its thermal conductivity is affected by mass density and porosity. The purpose of this study was to determine the heat resistance of partition board products to reduce the heat entering the room from outside by propagating through walls exposed to direct sunlight. The test method used is adopted from ASTM C177-13, namely the measurement of heat propagation with a modification of the heat source of 40 watts. In addition, mass density tests (referring to SNI 03-2105-2006) and water absorption (referring to ASTM D5229M-12) were also carried out on the product. The specimens were based on the formation of Singapore Highpolymer Chemical Product (SHCP) 2667 WNC polyester resin matrix partition board with weight fractions of 25%, 30%, and 35% chop strand mat (CSM). The test results show that the highest thermal conductivity value is found on the board with a weight fraction of 25%, namely 0.153 W/m.°C with a mass density of 1.16 g/cm3 and a water absorption capacity of 3.38%. However, the lowest thermal conductivity value was found in the fibre with weight fraction of 35%, namely 0.147 W/m. °C at a mass density of 1.24 g/cm3 and a water absorption capacity of 3.75%.
