Pengembangan konsep kendaraan Low-Cost Green Car (LCGC) dan zero emission menjadi fokus penelitian pada beberapa negara. Hal ini dilatarbelakangi cadangan bahan bakar minyak yang terus menurun dan bahaya pencemaran lingkungan. Motor listrik merupakan satu – satunya penggerak utama yang dapat diaplikasikan pada mobil listrik yang mengusung kedua konsep tersebut. Pada generasi awal pengembangan mobil listrik, motor DC menjadi solusi yang paling sesuai dikarenakan kemudahan pengoperasiannya dan pengaturan kecepatannya. Setelah teknologi kontrol vektor untuk motor induksi ditemukan dan dikembangkan, motor induksi mulai dipakai oleh beberapa pabrikan mobil listrik. Pada kontrol vektor, fluks dan torsi pada motor induksi dapat dikendalikan secara terpisah sehingga pengaturan motor induksi menyerupai motor DC. PMSM merupakan satu – satunya jenis motor listrik yang mampu menyamai motor induksi sebagai penggerak mobil listrik. Namun, PMSM memiliki kekurangan yang sangat vital yaitu mudah mengalami kerusakan magnetisasi akibat panas atau reaksi armature, sehingga diperlukan penelitian lebih lanjut untuk mengaplikasikan PMSM pada mobi listrik. Motor listrik jenis SRM banyak digunakan pada mobil hybrid yang memadukan penggunaan mesin berbahan bakar minyak dengan motor listrik. SRM memiliki banyak kekurangan apabila diaplikasikan pada mobil listrik berskala kecil namun sangat sesuai untuk diaplikasikan pada mobil listrik berskala besar seperti bis.
This study is aimed at knowing the problematics of german education students who have never gotten german lessons in previous education levels. This study belongs to descriptive qualitative. The population in this study is German Education students of State University of Makassar, class of 2019.

Penelitian dilaksanakan di kecamatan pesisir dan dua kecamatan kepulauan di Kabupaten Pangkep, pada bulan Desember 2012- April 2013. Data primer diperoleh dari pengamatan di lapangan dan wawancara dengan responden melalui Focus Group Discussion. Pengambilan data sekunder dari instansi terkait. Analisis di gunakan dengan A’WOT mengaplikasikan Program Expert Choice 2000. Hasil analisis menunjukan bahwa pengelolaan perikanan rajungan, mengandalkan kekuatan dan peluang untuk mengatasi kelemahan dan ancaman. Kriteria komponen kekuatan menempatkan prioritas relatif pertama minat nelayan dan masyarakat pengelolaan rajungan tinggi, peluang menetapkan target PEMDA dalam pengelolaan perikanan rajungan tinggi, kelemahan ditetapkan kordinasi dan implementasi kelembagaan masih rendah, ancaman ditetapkan jumlah alat tangkap rajungan semakin meningkat. Urutan prioritas alternatif kebijakan pengelolaan perikanan tangkap rajungan adalah: a) Penciptaan mata pencaharian alternatif; b) Penegakan hukum dan peningkatan kapasitas kelembagaan; c) Penggunaan alat tangkap yang ramah lingkungan; d) Restocking rajungan; e) Pengelolaan perikanan rajungan berbasis zonasi dan f) Pengembangan budidaya rajungan.</p><p><br />The effort to make improvement in a management policy of crab fishing is a solution to achieve suistainable resource management system. The purpose of this study is to examine an alternative management policy in crab fishing. This research gives an input for the government to regulate the crab fishing management. Research conducted in sub districts of all coastal and two islands in Pangkep districts in December 2012-April 2013. The primary data obtained from the field observations and interviews with respondents through Focus Group Discussion. Collection of secondary data was done by collecting data from the relevant agencies and recording data from collector. Data were analyzed using A’WOT analysis and Program Expert Choice 2000. The results of the analysis showed that the crab fishing management, relying on the strengths and opportunity to address the weaknesses and threats. The first priority of the strength component criteria were relative interest crab fishermen and management of high society, high target of local government in the management of crab fishing was opportunity component, coordination and implementation of institutional became a weakness component, and increasing number of crab fishing gear was became Threats. Recommendation of alternatives management for swimming crab include: a) Development of alternative livelihoods, b ) Law enforcement and institutional capacity building; c) Use of environmentally friendly fishing gear ; d ) Restocking of crab; e ) Crab fisheries management based on zonation and f ) crab aquaculture development.<br /><br /></p>
Draining traditional boat water efficiently is sometimes considered to be of little importance to most fishermen. Because it is considered a normal thing without realizing it can be detrimental, both in terms of time and work. One of the things that often makes the use of draining water less efficient is that the draining of boat water is still done manually with human intervention. So that fishermen are preoccupied with removing puddles of boats and hindering their work. Based on the above problems, this study aims to make a traditional boat water drain control system automatically. This tool functions to control the volume of water in the boat as well as turn on and turn off the water pump engine automatically. This tool is able to remove puddles that enter the fishing boat automatically. The working principle of this tool, if the water hits the sensor ≥ 5 cm, the pump and buzzer will start and if the water doesn't hit the sensor, the pump and buzzer will automatically shut down.
This study was conducted to examine the influence of personality, organizational culture, and organizational commitment to the performance of the employee with organizational citizenship behavior as the intervening variable at KPP Pratama Lhokseumawe. The population used in this study was 83 respondents, while the sample of research as many as 79 respondents based on the questionnaires. The samples were taken using Census sampling technique. The hypothesis tests were conducted by using path analysis with the help of SPSS. The results of hypothesis tests indicated that personality, organizational culture, and organizational commitment have significant effects on organizational citizenship behavior. Organizational culture and organizational commitment have a significant effect on the performance of the employee, while personality had no significant effect on the performance of employees. The result of examination of mediation variable showed that organizational citizenship behavior could mediate the relationship between personality and organizational culture to partial employee performance. Whereas in organizational commitment, organizational citizenship behavior perfectly mediated the performance of employees.
