Judul: Analisis Fenomena Oligopsoni dalam Distribusi Hortikultura dalam Pasar Modern: Perspektif Ekonomi Politik (Periode Januari – Mei 2013)
Abstrak: Distribution of agriculture product is an important things in delivered products that produce by farmers to the community to consume. The infiltration that modern market do in distribution of agriculture products affect the distribution process. This research was focusing in market efficiency and price transmission of six horticulture products that produce in Indonesia and sold by for big modern market. The methods that used in this research are distribution’s margin analysis, price transmission, and descriptive kualitative method.

Judul: Analisis komparasi saluran pasar tradisional dan modern pada komoditas sayuran di Kecamatan Pangalengan Kabupaten Bandung
Abstrak: Vegetable is one of the important horticultural commodities that potential to be developed because it has a high market demand both from within and outside the country. Although the trade balance value was still negative, the export trend of vegetable from 2005 to 2010 is positive 10 percent. Modern market developments such as the export and food service industries such as restaurants offer higher returns to farmers. But the Modern market has the requirement related to quantity and consistency of vegetable quality. Therefore, it is important to analyze marketing of vegetable in Modern market. Pangalengan is the vegetable production centers in West Java that contribute quite big in the National vegetable production. In addition, the district is also targeted to make contribution to increase the export of vegetable, especially to Singapore. Along with the development of a Modern market, farmers started supplying to the Modern market that enforces the selling price fixed based on agreements and offer a higher selling price than traditional markets. Because of fluctuating prices, traditional market trigger unintegrated market price at the level of farmers and retailers. The aims of this research are to: (1) analyze the marketing aktivities of vegetables in Pangalengan; (2) analyze the efficiency of the Modern and traditional market channels of vegetables in Pangalengan; and (3) analyze the impact of Modern market channels against farmers and traditional market channels. Research location determined purposively in three villages in the District of Pangalengan because of the highest vegetables productivity i.e. Margamekar Village, Pangalengan Village and Margamukti Village. Vegetables in this research are potato, tomato, cabbage and carrot. Data analysis was done qualitatively and quantitatively. Qualitative analysis was conducted to find out the vegetable market institutions, marketing functions, marketing channels, and the impact of modern market channels to farmers and traditional market channels. Microsoft Excel and Eviews software are used to analyze price integration of vegetables on traditional market with ordinary least square (OLS) model that adapted from Ravallion Model. The results showed that the marketing institutions of vegetables in traditional market channels are traders I, traders II, wholesale and retailers. While for marketing institutions on the modern market are of traders III, exporters, and restaurant. The marketing function that carried out by marketing institutions who supply vegetables to traditional market generally consists of: (1) facilities functions such as sortation, risk, cost, and market information; (2) physical functions in the form of transportation and storage; and (3) exchange functions such as sales and purchase.

As for the commodity tomato, integrated strong because information to farmers more open and distributed quickly. The impact of

Judul: Pembuatan Film Tipis Lithium Niobat (LiNbO3) Menggunakan Metode Chemical Solution Deposition (CSD) dengan Variasi Kecepatan Putar (Rpm).
Abstrak: Film tipis merupakan salah satu aspek yang mendapat perhatian sangat besar dalam bidang material, karena film tipis merupakan material menarik yang memiliki sifat optik yang sangat tergantung pada konstanta dielektrik, indeks bias, dan energi gap. Lithium Niobat (LiNbO3 ) dapat digunakan sebagai pelapis pada film tipis karena memiliki sifat piezoelektrik, electrooptical, pyroelectrical dan photorefractive yang sangat baik. Film tipis Lithium Niobat (LiNbO3 ) ditumbuhkan menggunakan metode Chemical Solution Deposition (CSD) dengan variasi kecepatan 3500 rpm, 5000 rpm, 6500 rpm, dan 8000 rpm. Metode ini memiliki keunggulan dapat mengontrol stokiometri film tipis dengan kualitas yang baik, prosedur yang mudah dan membutukan biaya yang relatif murah. Energi band gap yang dihasilkan dari film tipis Lithium Niobat (LiNbO3) berkisar antara rentang 2.1 eV – 2.8 eV dengan indeks bias berada pada rentang 2.18-3.2. Film tipis LiNbO3 memiliki parameter kisi a=b=5.54Ǻ dan c = 16.35 Ǻ. Struktur morfologi film tipis adalah permukaan yang homogen dan ukuran kristal berada pada rentang 0.417 μm – 0.680 μm.
