Abstract

In this study, we found that BVI03 an alkaloid compound isolated from B. virgate induced antiproliferation against the human cervix carcinoma cell line HeLa. A MTT assay indicated that BVI03 had a strong tumor inhibition ratio (IC50 = 0.126 mg/L), which was superior to that of tamoxifen (IC50 = 2.88 mg/L). This study also investigated the mechanism of antiproliferation induced by BVI03. Enzymatic activity using a colorimetric assay kit was performed to determine work mechanism of BVI03.  Our data indicate that p53 and caspase-3 are involved in the process of BVI03-induced antiproliferative in HeLa cell compare with untreated HeLa cells.

Abstract

Adapun tujuan dari penelitian ini adalah meningkatkan mutu kekeringan biji kakao hasil perkebunan rakyat dari kadar air ± 12 % (musim kemarau) dan ± 25 % (musim hujan) menjadi < 7,5 %. Tujuan jangka panjang penelitian ini adalah meningkatkan mutu biji kakao kering hasil produksi tradidisional agar dapat bersaing dengan produk kakao dari Negara eksportir lainnya. Metode penelitian yang digunakan adalah sebagai berikut: penelitian  direncanakan 2 tahun, kegiatan tahun pertama antara lain; melakukan pengujian mutu biji kakao hasil produksi petani, kegiatan ini meliputi analisis kandungan kadar air dengan menggunakan metoda oven 150 ºC, kandungan aroma (metil pirazin) dengan teknik kromatografi gas (perego et al. 2004). Uji lainnya seperti kadar lemak, kadar jamur, kadar kulit dan kotoran serta pengamatan fisik dan warna. Kegiatan selanjutan adalah merancang alat pengering buatan yang menggunakan uap air sebagai energi untuk mengeringkan biji kakao, temperatur dalam kotak pengering dipertahankan maksimum 60ºC. Dari hasil penelitian disimpulkan bahwa alat pengering biji kakao hasil penelitian dapat mengeringkan biji kakao sampai 7,15% dalam waktu 30 jam dan 5,64% dalam waktu 35 jam, serta telah memenuhi standar mutu kakao SNI 01-2323-2000. Kata Kunci: Biji kakao, pengeringan, mutu.

Abstract

The Gibbs surface excess was examined by using surface tension vs. concentration curve and a new concept for the surface excess is presented based upon data from the evaporation rate of water, the activation energy of evaporation, and the BAM images for surfactant solution. As the result, the surface excess was found to concentrate not at the air/water interface but at some depth apart below the interface as bi-lamellar aggregates.

Abstract

 The Efficacy of Pendimethalin Herbicide Mixtures and its Effects on Weed and Yield of SoybeanABSTRACT. Field research has been conducted in Experimental Farm of Agriculture Faculty University of Syiah Kuala Banda Aceh from March to July 2006 for evaluation efficacy of pendimethalin herbicide mixtures and its effect on weed and yield of soybean. Pendimethalin+imazetaphyr herbicide at dosage of 1.0 kg+70 g.a.i. ha-1 could decrease dry weight weed and increase percentage of weed control. Dried seed yield were higher when pendimethalin+imazetaphyr herbicide was applied at dosage 1.0 kg + 70 g.a.i. ha-1.

Abstract

Comparison of object Oriented Classification With Maximum Likelihood Classification on Land Cover Maaping in District of Gayo LuesABSTRACT. Image classification method used critically effects the classified image produced as well as its accuracy. One of the recently introduced classification methods is Object-Oriented Classification (OOC). The fundamental difference between this method and that of Maximum Likelihood Classification (MLC) lies on the basic unit of image analytical prosses, i.e., image object or segment, and not on a single pixed. The new classification method uses a segmentation procedure with a hierarchical approach which allows an addition of an object  characteristic to other information related  to the classified object, such as from, texture, and context. This object or segment is formed because the smallest region has a larger area than the image pixel. In this study, MLC and OOC classification methods were compered using Landsat ETM+ image for Gayo Lues District of Aceh. The objective of this study was to map out land cover/ landuse classes of the research area and compare the result and its accuracy using the MLC and OOC classification methods. Result  of the study showed that a higher, more detailed, hierarchical land cover/ landuse class with a higher accuracy was obtained using OOC classification method which corresponds better to the contextual condition in the field compared to that of the pixel- based classification method.

Abstract

Changing of minimum wage policy option by the actors in 2006 is caused mainly by any change from internal aspects of policy subsystem directly, especially the change of secondary aspects of two advocacy coalition of minimum wage in South Sulawesi. This case mainly influenced from implementation the decentralization aspect where labors or group of labors have also any opportunity to involve in wage policy debate or in the forum of board of Provincial Waging. Furthermore, the Board of Manpower (Dinas Tenaga Kerja) of South Sulawesi Province which is identified as the policy broker has an important role to meet policy subsystem’s different strategies. As a result, conflict of minimum wage between labors and employers can reduce and they can act as a mediator to chooce the wage policy.Keywords: minimum wage, advocacy coalition framework

This requires community support which is an important factor in ecotourism development. The purpose of this study was to find out the community's carrying capacity in the development of Tahura Pocut Meurah Intan ecotourism through 3 parameters, which are acceptance for visitors, participation in ecotourism development and participation in conservation. The study used descriptive method, while data was collected from questionnaires to villagers around the Tahura Pocut Meurah Intan, which are the Suka Damai Village, the Suka Mulia Village, and the Aceh Saree Village. The results showed that the community's carrying capacity for ecotourism development in the Tahura Pocut Meurah Intan in the SukaDamai Village was classified as supportive (70%) while the other two villages, the SukaMulia Village and the Aceh Saree Village were classified as very supportive (76.6%). It can be concluded that the community's carrying capacity in the development of the Tahura Pocut Meurah Intan as ecotourism area is very supportive, in terms of visitors' acceptance, community participation in ecotourism development, and community participation in conservation effort.

Abstract

Tulisan ini memaparkan hasil Penelitian yang dimaksudkan untuk memberikan salah satu solusi terhadap masalah konsumsi energi listrik bagi perangkat elektronik berdaya kecil, misalnya sensor. Smartphone yang umumnya memiliki port audio dapat mengeluarkan sinyal audio. Dengan menggunakan perangkat lunak aplikasi pembangkit sinyal, maka dapat dihasilkan berbagai macam sinyal audio pada port audio. Keluaran sinyal audio, yang salah satunya berupa sinyal sinusoida yang merupakan bentuk tegangan AC (bolak-balik), dapat diubah besar tegangannya dan selanjutnya disearahkan sehingga menghasilkan tegangan DC (searah) dengan menggunakan rangkaian penaik tegangan (voltage multiplier) dan penyearah (rectifier). Hasil yang diharapkan adalah berupa tegangan DC 5 V yang dapat digunakan sebagai catu daya bagi berbagai perangkat elektronik berdaya kecil.
