    The end of Sibuak line feeder facing a voltage drop phenomena. This phenomena is contributed by the length of the transmission line, as well as the distribution line. This paper purposes a reconfiguration of Sibuak feeder in order to reduce amount of power losses and the drop voltage. The design of reconfiguation Sibuak feeder refers to PLN standard (SPLN 1,1978).This reconfiguration uses LBS status updating approach which is triggered from Normally Close (NC) into Normally Open (NO) or in the refers condition. Beside that, it is required load transfer from Sibuak Feedr in to Cadika Feeder. The result of ETAP 12.6.0 software indicates that the reconfigured Sibuak Feeder able to achieve lowest voltage on 18,162 kV with power losses shows 1,652 and 1,186 MVAR respectively.

    Modulus puntir merupakan materi yang asing di kalangan pelajar, mereka lebih akrab dengan materi modulus Young. Ini dikarenakan sulitnya seorang guru menjelaskan fenomena dan eksperimen yang pasti tentang materi ini.  Percobaan sederhana penentuan modulus puntir batang besi telah dilakukan dengan menggunakan metode pelengkungan. Metode yang digunakan adalah dengan analisis regresi linier tanpa bobot hubungan antara sudut puntir dengan massa beban tambahan, dan pengambilan data untuk penentuan nilai modulus puntir batang besi dilakukan dengan variasi massa beban. Setiap variasi massa, sudut yang terbentuk diukur menggunakan busur derajad sebanyak 7 kali. Koefisien modulus puntir dapat dihitung dari gradien garis hasil regresi antara sudut puntir dengan massa beban tambahan. Setelah dilakukan regresi dari 7 data eksperimen, diperoleh nilai koefisien modulus puntir batang besi sebesar G=(0,055 ± 0,007) × 1012Pa, nilai ini tidak jauh berbeda dengan perkiraan nilai modulus puntir pada bahan-bahan yang sejenis lainnya

    Resilience is the ability of individuals to adjust and adapt to change, the demands and disappointments that arise in life. Resilience can affect individuals in coping with stress, by Therefore, the individual must have resilience. The level of stress each indvidu influenced by an individual\u27s ability to perform self-adjustment to the changes that occur. Good resilience can help a person in the face of stress. The purpose of this study was to determine the relationship between resilience ourselves on the level of stress on clerkship Riau University School of Medicine. Cross sectional analytic correlative design to 83 clerkship who selected by total sampling. Collecting data using questionnaire resilience based Connor- Davidson Resilience Scale (CD-RISC) and the Medical Student stressor Quisionaaire (MMSQ) using online questionnaire (goole docs). Data analyzed bivariat by Spearman correlation test and p value = 0.552, r = -0.066, meaning that there is no meaningful relationship with a weak correlation between the resilience of the level of stress on clerkship Riau University School of Medicine

    Every community is in need of soil in his life, in the indigenous communities have a name which is the customary rights of indigenous peoples rights group over a piece of land called communal land. Implementation of communal rights should be based kapentingan national and state that does not conflict with other regulations, can be seen in Article 3 of Law No. 5 of 1960 on the Basic Regulation of Agrarian, but it can also be seen in Article 2 paragraph (2) Regional Regulation West Sumatra province that benefits for the benefit of indigenous peoples and in the rules of customary law Minangkabau any decision should be based on consultation and consensus. However, the case for customary land were sold and its use no longer compatible with the existing rules. The purpose of this thesis, namely: first, to know the background of customary land rights disputes in villages Base, both to know the management of communal land by indigenous people in the village base, third mediation customary land rights in villages Base.This type of research can be classified in this type of sociological research, because in this study the authors directly conduct research on location or area under study in order to provide a complete and clear picture of the problem under study. This research was conducted in villages Base districts Base Koto Baru, while the sample population is a whole party with regard to the issues examined in this study, the data source used primary data and secondary data, data collection techniques in this study with interviews and literature study.From the research, there are three main things that can be inferred. First, the background or the causes of communal land dispute is due to the daily needs of the different indigenous peoples so as to meet the needs of the community will carry out the various ways that lead to the emergence of disputes. Second, their land use is not in accordance with the interests of indigenous peoples have even cause harm to indigenous people themselves. Third, indigenous peoples are less trusting density Adat (KAN) in resolving disputes resulted in communal land settlement to the District Court. Suggestions writer, first, indigenous peoples must mengedapankan common interest and does not conflict with personal interests so that there are no losers. Secondly, the use of communal land should be guided by the existing rules so that there is no abuse of power. Third, KAN should perform its functions optimally, so that indigenous people will trust KAN in resolving land disputes which occurred in the village communal Base

    Analisis Pengaruh Harmonik terhadap Peningkatan Temperatur pada Trafo Distribusi 3 Fasa 400 KVA di Fakultas Teknik Universitas Riau.

    Distribution transformer has an important role in the distribution of electric power in a distribution system. So that the transformer can operate with both the condition of the transformer must be in a stable condition. One of the things that can damage the transformer is non-linear load, such as computers, printers, air conditioning (AC) equipment lab in every department and equipment other electronics that may cause harmonic on the network power systems, content of harmonic high can cause a condition of distribution transformer overheats and if not treated immediately will cause transformer life time becomes shorter. This study aimsto determine the harmonic correlation to the increase of temperature on the distribution transformer in the Faculty of engineering University of Riau
