Rancangan Konfigurasi Jaringan Distribusi Material Pengeboran Untuk Mengurangi Biaya Transportasi:Studi Kasus Di Sebuah Perusahaan Migas
Pengeboran merupakan kegiatan utama di usaha hulu migas yang bertujuan untuk meningkatkan produksi minyak dan gas guna memenuhi kebutuhan energi nasional. Jumlah rig yang terbatas, kendala dalam pembebasan lahan dan penyiapan lokasi pengeboran mengakibatkan jadwal pengeboran yang sangat dinamis dan berubah – ubah. Hal ini berdampak pada ketidakpastian permintaan dan suplai yang tinggi, jumlah material persediaan yang berlebih di satu gudang, dan shortage di gudang lainnya. Dampak lainnya adalah timbulnya kegiatan BAU (Bantuan Antar Unit) material pengeboran sehingga membebani perusahaan karena terjadinya double cost pada biaya transportasi. Biaya rata-rata yang timbul akibat kegiatan BAU dalam kurun waktu 5 (lima) tahun terakhir adalah sebesar Rp. 46.261.256.305. Penelitian ini bertujuan untuk merancang konfigurasi jaringan distribusi material pengeboran yang mampu mengurangi terjadinya double cost pada biaya transportasi dan menentukan penghematan biaya transportasi yang dicapai dengan rancangan konfigurasi jaringan distribusi yang baru. Langkah – langkah dalam penelitian ini adalah (1) penetapkan desain jaringan distribusi; (2) grouping; (3) pemetaan lokasi gudang; (4) evaluasi gudang existing; (5) menentukan lokasi distribution center; (6) penghematan biaya; (7) analisis. Penentuan lokasi dilakukan dengan menggunakan metode center of gravity. Hasil penelitian adalah penetapan strategi distribusi melalui distribution center untuk mengurangi terjadinya double cost. Terdapat 4 (empat) lokasi distribution center terpilih diantaranya terletak pada Kecamatan Kota Baru, Kabupaten Muara Enim, Kabupaten Indramayu dan Kabupaten Kutai Timur. Apabila dibandingkan dengan konfigurasi jaringan distribusi saat ini, penelitian ini menghasilkan penghematan biaya transportasi sebesar 27,77% atau Rp. 26.613.231.154 (dua puluh enam miliar enam ratus tiga belas juta dua ratus tiga puluh satu ribu seratus lima puluh empat rupiah).

Steam Power Plant is the backbone of electricity sector in Indonesia. Steam Power Plants supply 27.5 GW to the grid, in which 90% of them is coal fired. Today, several Coal Fired Steam Power Plants face a supply problem; One of them is XYZ Coal Fired Steam Power Plant. The 20-year coal supply contract will end soon, but the supplier is unable to extend the contract due to the declining quality of coal in mining. Even if there are four candidates of provider to supply coal, but the available coals from those four companies present several problems for the company. Those problems are the coals offered have lower caloric values than the caloric value designed for the power plant, continuously changing coal chemical properties may damage equipment, especially for firing system in boiler and emission control, and it is the tightening government regulation on power plant emission. It is necessary to make assessment about the effects of coal switching on equipments. The risk assessment focuses on effects of each coal sample on equipment in plant site, especially the equipment closely related to firing process, i.e. boiler, electrostatic precipitator (ESP), and Seawater Flue Gas Desulfurization (SWFGD). Risk Breakdown Structure (RBS) is employed to map problem and problem root in equipment. Risk analysis and evaluation use House of Risk (HOR), meanwhile Net Present Value (NPV) is used to evaluate financial traits. NPV analysis is calculated based on revenue due to the savings in coal costs as cash in, and the costs required for risk mitigation actions as cash out. Based on 31 risk events and 37 risk agents identified, HOR analysis shows one environmental factor, i.e. emission, becomes the highest risk as each coal has high ash content; hence it is necessary to improve emission control. Three of four candidates show high NPV values suitable for the company to maximize profitability
Ethnic Group Identification and Group Evaluation Among Minority and Majority Groups: Testing the Multiculturalism Hypothesis
Following social identity theory, the author hypothesized that members of minority groups are more likely than majority group members to endorse multiculturalism more strongly and assimilationist thinking less strongly. In addition, the multiculturalism hypothesis proposes that the more minority groups endorse the ideology of multiculturalism (or assimilationism), the more (or less) likely they will
be to identify with their ethnic in-group and to show positive in-group evaluation. In contrast, the more majority group members endorse multiculturalism (or assimilationism), the less (or more) likely they are to identify with their ethnic group and to show negative out-group evaluation. Results from 4 studies
(correlational and experimental) provide support for this hypothesis among Dutch and Turkish participants living in the Netherlands.
Foreign Language Usage and National and European Identification in the Netherlands
Multilingualism is considered a pathway to European identification but might also undermine national identification. We examine regular foreign language usage and two psychological constructs that can explain the relationship between multilingualism and European and national identification in the Netherlands: greater mental openness and a deprovincialized worldview. Using structural equation modeling, the results of two studies conducted with national Dutch samples show that foreign language usage predicted greater mental openness (cultural in Study 1, and cognitive in Study 2), which then predicted greater European identification. Foreign language usage also predicted greater deprovincialization which, in turn, predicted lower national identification.This research was funded by a fellowship to the first author by

Investigating Criteria That Seventh Graders Use to Evaluate the Quality of Online Information
This article presents qualitative findings from a study that examined the types of criteria that middle school students use to evaluate the quality of online information and sources for a Web-based research assignment. Open-constructed responses from four critical evaluation items were compiled from diverse seventh graders in a representative, two-state, stratified random sample (n = 773). Content analysis revealed that many students used a range of unacceptable or superficial criteria to determine the author of a website and whether that author is an expert, to state the author\u27s point of view, and to provide reasoned evidence about the overall reliability of a website. Criteria and evidence patterns that students used for each of the critical evaluation tasks are shared, as well as implications for instruction

Emotionele distantie en integratie: Iraanse politieke vluchtelingen in Nederland
This article focuses on subjective feelings of integration in Dutch society or the extent to which Iranian refugees feel Dutch and have a positive attitude towards the Dutch. The results show that both aspects of subjective integration are relatively independent, but for the two aspects a similar explanatory model was found. Participation on the labour market or in the educational system had a direct positive effect on feelings of integration. Level of education and frequency of voluntary contact with the Dutch had a positive effect on perceived cultural conflict, which, in turn, was related to feelings of integration.
