Analisis Perdagangan Bilateral Indonesia Indonesia dengan Malaysia Periode 2003-2012

This study aims to determine (bilateral) development and comparison of trade between the two countries, Indonesia and Malaysia for the period 2003 to 2012 As this study shows the shape of trade, and the indicators that affect trade between Indonesia and Malaysia. The data used are secondary data obtained from the BPS (Central Bureau of Statistics) and the World "series for 10 years. "Variable used, among other things, the value of exports and imports, the price level and GDP.Methods for quantitative data analysis and descriptive data analysis. Indonesia bilateral trade with Malaysia calculations using the formula expor-import price index is likely to rise sharply, particularly in terms of export and import small. Taken together, the independent variable is the dependent variable to explain export function. In terms of the commercial value of Indonesia and Malaysia in 2003-2012, an average exchange rate of Indonesian trade showed 100 percent, this means that the state of Indonesia and Malaysia are still mutually beneficial bilateral trade import and export business midst of the economic turmoilKeywords: Bilateral, exchange rate, index of export and import of Indonesia

Analisis Kualitas Desain dan Kunjungan Situs Pemerintah Daerah di Indonesia

Penelitian ini bertujuan untuk menganalisis kualitas desain dan statistik kunjungan situspemerintahan daerah (PEMDA) tingkat kabupaten/kota yang ada di Indonesia. Kualitasdesain didasarkan pada indikator kualitas yang dikembangkan oleh penelitiansebelumnya. Penelitian menggunakan data populasi situs PEMDA di Indonesiaberdasarkan hasil observasi situs pada Mei 2013. Analisis dilakukan bersifat deskriptifserta inferensial yang menunjukkan hasil bahwa terdapat variasi antardaerah terkaitkualitas desain maupun kunjungan terhadap situs PEMDA. Walaupun secara umumdapat dikatakan bahwa kualitas desain situs PEMDA di Indonesia masih kurangmemuaskan. Rendahnya kunjungan terhadap situs PEMDA mengindikasikan kurangmenariknya situs PEMDA bagi pengguna informasi meskipun dapat menandakankemungkinan tidak adanya kepedulian pengguna informasi atas kondisi dan pelaksanaanpemerintahan di daerah mereka. Selain itu ditemukan bahwa tingkat pendapatan aslidaerah dan ukuran daerah merupakan salah satu faktor yang menentukan kualitas desainsitus PEMDA di Indonesia

Stress and Deformation Study on Castellated Steel Beam with Tapered Shape and Hexagonal Openings

Castellated steel beam is a beam with a regular section cut into half with a particular pattern and regrouped with welding to increase its height compared to the original. This structure element has been developed in building constructions since many years ago. However, its uniform section along the span will make the modification no longer effective in cantilever structure, unless it has additional adaptation. Therefore, in this study, it is proposed to use a castellated steel beam with a tapered shape to be applied as cantilever structures. A steel beam with IWF section 150x75x5x7 is the primary sample type in this research. Some variations were made such as openings angle for 450 and 500, openings space for 50 mm, 70 mm, and 90 mm, openings diameter for 50 mm, 75 mm, and 100 mm, and span length for 2 m, 2.5 m, 3 m, and 3.5 m. Two open-source software namely FreeCAD and LisaFEA were used to draw solid 3-dimensional samples and to conduct the numerical analysis to determine stress and deformation respectively. From the result, it is known that the smallest stresses and deformations can be achieved by a different angle of openings, openings space, and diameter for each span length

Safety and Fatigue Risk Factors among Online Motorcycle Drivers in Depok City, Indonesia

In Indonesia, the motorcycle is often the first choice for transportation, and has been especially popular as a taxi service since the creation of an online request system, known as Ojek Online. Unfortunately, this online employment has less engagement than traditional taxi companies and other public transportation companies in research area that can give guarantee for ensuring their drivers’ safety and health. Many drivers are exposed to uncontrolled risks. Our research concerns drivers’ health and safety factors. The goal is to determine which factors most affect a drivers’ actions and safety. This study utilises both qualitative and quantitative research. Our qualitative research gathers in-depth health complaints made by drivers, especially in regard to their musculoskeletal symptoms. Our quantitative research focuses on other aspects that affect their ability to drive safely, such as their durations of rest, bad driving habits and work hours. The sampling method used in this research could be used to represent the entirety of the drivers’ health and safety factors. The respondentsin this research come from Depok, Bekasi, Bogor and Tangerang. The randomly sampled respondents agreed to answer the questions by themselves. The number of our respondents is 70. Our study found that the most influential factor affecting safe driving ability is fatigue. The results show that 62.85 percent of respondentsexperience fatigue while driving. Further, the data shows an imbalance among drivers in regard to age, work hours, total distance driven and rest time. Drivers’ bad habits also negatively impact the safety of the rider. The most reported health effect was musculoskeletal symptoms in the lower part of the drivers’ back. The second most reported health effect was in regard to the drivers’ buttocks and wrists. The results of this research show that musculoskeletal disorders and fatigue affect the drivers’ condition, which can negatively impact drivers’ and customers’ safety.

Pengaruh Variasi Dolomit Material Lokal Kabupaten Bangkalan Sebagai Subsitusi Agregat Dalam Pembuatan Batako Terhadap Kuat Tekan Dan Absorbsi

Batako dalam penelitian ini dibuat dari campuran semen, tepung dolomit, pasir dan air. Tujuan penelitian adalah mencari bahan alternatif pengganti pasir dalam pembuatan batako. Komposisi sampel digunakan perbandingan semen : pasir = 1 : 8 (dalam % volume). Substitusi pasir terdiri divariasi dari 0%, 25%, 50%, 75%, dan 100%. Sampel uji dibentuk batako hollow dengan ukuran 40 cm x 19 cm x 10 cm. Setelah pengeringan secara alami 28 hari ditemukan rata-rata kuat tekan maksimum 27,68 kg/cm2 yaitu pada komposisi dengan penggunaan 75% dolomit dan minimum 14,15 kg/cm2 pada penggunaan 0% dolomit, penyerapan air maksimum 18,34% pada komposisi dengan penggunaan 100% dolomit dan minimum 12,04 % pada komposisi penggantian 25% dolomit; Batako yang dihasilkan tergolong type IV; Komposisi dengan penggunaan 75 % dolomit tehadap substitusi pasir menghasilkan kuat tekan lebih baik daripada komposisi dengan penggunaan 0% dolomit terhadap subsitusi pasir, jadi dapat disimpulkan bahwa tepung dolomit dapat dijadikan sebagai subsitusi pasir pada pembuatan batako
