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. Result of this research show there is a variance in market structure on each level of distribution and there is an indication that oligopsony phenomenom happened in distribution in modern market.

Judul: Dampak Perkembangan Toko Modern Terhadap Kinerja Pedagang Produk Pertanian Pada Pasar Tradisional di Kota Bekasi
Abstrak: Modern stores have been present in major cities in Indonesia since last three decades. With the rapid growth of the ritail sector, in 1998, Indonesia made a deal with the IMF that foreign ritelers can freely invest in Indonesia. This has led to the perception that traditional markets are the real victims of the ritail sector competition which leads to reduced consumer due to modern shops can provide advantages that can not be provided by traditional markets such as convenience, product quality and safety. Traditional market traders who sell the majority of agricultural products are in danger because these commodities are also a large part of product line supermarkets and hipermarkets. This study aimed to analyze changes of agricultural products trader performance in traditional markets as the growing number of modern stores in Bekasi and the factors that influence changes of revenue and profits traders of agricultural products. Results of paired t-test showed that there are a change in their respective markets of the variables revenue, profit, operating hours, circulation of goods, number of buyers, the number of customers and the number of employees experiencing. At the revenue variable, real influential factors are a gender dummy, education level, number of kiosk, spacious kiosk, main commodity is rice dummy and main commodity is fresh fruits and vegetables dummy. At the profit variable, real influential factors are a gender dummy, level of education, trading experience, number of kiosk, spacious kiosk and location dummy.

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.
