Abstract

Pada sistem distribusi tenaga listrik yang menggunakan sistem Bintang 4 kawat Multy Grounded Common Neutral (Y-4 W-MCGN), jika kawat netral hilang maka tidak akan ada lagi sistem tersebut, karena sistem  MGCN  akan terselenggara dengan baik hanya jika ada saluran netral, sehingga hilangnya kawat netral di beberapa tempat pada saluran merupakan suatu kondisi tidak normal dan akan menyebabkan resiko yang tidak baik terhadap performance operasi sistem distribusi tenaga listrik dan kualitas pelayanan beban di sisi pelanggan.

Abstract

This study was conducted to develop an instructional model of mechanical skill learning for the STM students to improve their cognitive, psychomotoric skills, motivation, and creativity. To develop an adequate instructional model, 15 experts were consulted. Based on the result of consultation, the model was revised. The revised model was then tried-out to 20 students of the STM Bengkulu and 17 students of the STM Curup. The result of try-out showed that the developed test items had moderate validity and reliability. The revised instructional model was applied to 25 students of the STM Bengkulu and 30 students of the STM Curup. The result of the study showed that the integrated instructional model was effective to teach mechanical skill, highly effective to increase students motivation, and moderate to develop creativity

Abstract

Wakaf, sebagai salah satu lembaga sosial dan ekonomi umat, memiliki potensi yang sangat besar dalam mendorong upaya peningkatan ekonomi umat. Sebagai suatu negara yang memiliki jumlah penduduk yang sangat besar dan mayoritas muslim, Indonesia perlu menggali dan mengembangkan potensi lembaga keagamaan ini. Kombinasi antara perintah agama dan nilai-nilai sosial dapat menjadi sandaran ideologis yang kuat bagi pemerintah dalam mengatur pengelolaaan wakaf agar makin berkembang dan produktif. Penelitian ini menelaah bagaimana kedudukan hukum tanah wakaf di kabupaten sebelum dan sesudah berlakunya Undang-Undang Nomor 41 Tahun 2004 Tentang Wakaf sekaligus mengidentifikasi faktor-faktor apa saja yang dapat mendukung dan menghambat upaya optimalisasi pemberdayaan wakaf. Penelitian ini menggunakan pendekatan sosio-normatif dan dilaksanakan di beberapa lokasi dalam wilayah Kabupaten Demak. Studi ini mengungkap fakta bahwa lembaga wakaf di Kabupaten Demak belum mampu meningkatkan kesejahteraan masyarakat. Hal ini dikarenakan banyak tanah-tanah wakaf di Kabupaten Demak tidak dikelola secara profesional dan kurang produktif. Untuk itu, ke depan dibutuhkan pembinaan profesionalitas para nazir agar lembaga wakaf dapat berkembang secara optimal dan inovatif sehingga kemakmuran masyarakat dapat terwujud secara merata.

Abstract

The parasitic level research and description of the parasitoid species which were parasitic towards Aphis gossypii (Glover) (Hemiptera : Aphididae ) origin the agroecosystem of the lowland and highland of South Sumatra has not been reported, although this information is needed as a foundation of biological control of A. gossypii in South Sumatra. The purpose of this study was to determine the parasitic level and provide information about the description of the parasitoid which were parasitic towards A. gossypii origin the agroecosystem of the lowland and highland of South Sumatra. Survey and exploration the parasitoid which were parasitic towards A. gossypii conducted at 11 sites in South Sumatra vegetable center.  The identification of parasitoid species was conducted in the laboratory of Entomology Department of the Faculty of Agriculture University of Sriwijaya. The results showed the parasitic level of Aphidius sp. and Diaeretiella rapae was higher during the dry season in both lowland and highland compared to the parasitic level of Aphelinus sp. However, Aphelinus sp. could only spread in the lowland. The main characteristics of Aphidius sp. (Aphidiidae) has shaped antennae filiform and segmented 13. The front wings have a triangular pterostigma. D. rapae, (Aphidiidae) has shaped antennae filiform and segmented 14. The front wings has a triangular pterostigma. The hind wing has a perfect basal cells. Aphelinus sp. (Aphelinidae) has an shaped goblets antennae and eight segmented and the last segments three of the antennae enlarged or club. Marginal venation long wings, while the venation postmarginal and stigma reduction. In addition there are two species of hyperparasitoid which were found to be parasitic towards parasitoid A. gossypii, were Ooencyrtus sp. and Aphiidencyrtus sp. (Encyrtidae) especially in the lowland.
