Judul: Studi Kasus Penanganan Pascapanen Komoditas Tomat di Koperasi Mitra Tani Parahyangan Cianjur.
Abstrak: Koperasi Mitra Tani Parahyangan merupakan koperasi yang bergerak dibidang hortikultura. Komoditas unggulan koperasi ini adalah tomat merah. Tujuan dari penelitian ini adalah untuk mengetahui saluran pemasaran tomat serta menganalisis penanganan pascapanen tomat di koperasi Mitra Tani Parahyangan. Metode yang digunakan dalam penelitian ini adalah metode studi kasus dengan data kualitatif. Teknik pengumpulan data dengan purposive sampling. Hasil penelitian menunjukan bahwa koperasi Mitra Tani Parahyangan memasarkan tomat ke beberapa supermarket di wilayah jabodetabek, pasar tradisional, serta restaurant di wilayah cianjur. Penanganan pascapanen di koperasi Mitra Tani Parahyangan khususnya komoditi tomat adalah pemanenan, pencucian, sorting dan grading, pengemasan, dan distribusi. Kualitas komoditi di koperasi masih dapat ditingkatkan dengan meminimalisir sentuhan terhadap komoditas dan menerapkan penyimpanan dingin.

Judul: Analisis Kemitraan Petani Tomat (Lycopersicum Esculentum) Pada Koperasi Mitra Tani Parahyangan (Studi Kasus : Anggota Kelompok Tani Mitra Tani Parahyangan, Cianjur Jawa Barat).
Abstrak: Farmers as entrepreneurs generally have a weakness in terms of technology, capital, market information and limited human resources. One effort that can be done to overcome these problems is through cooperation or partnership between the subsystems performed agribusiness. Mitra Tani Parahyangan is a cooperative engaged in horticulture who became a supplier to a modern market in the greater Jakarta area and traditional markets around Cianjur and members of the Mitra Tani Parahyangan Farmers Group is part of the partner farmers. The purpose of this study is to see how the partnership is held on the cooperative Generally partner farmers income is still greater than in non-partner farmers. Partnership benefits for farmers is higher income, higher selling prices, guaranteed markets, and as well as the coaching. Logistic regression analysis showed the age and price guarantees have a significant effect at α = 0.05 level against the decision of farmers to partnership.

Judul: The Exploration of Discrete Logarithm over Finite Field GF(3m)
Abstrak: The security of many public~key algorithms is based on the problem of finding discrete logarithms. The generalized discrete logarithm problem is the following: given a finite cyclic group G of order n, a generator a of G, and an element fl E G, find the integer x, 0 ~ x ~ n - 1, such that 0: = fl. Algorithm for discrete logarithm problem focused on Menezes et al. (1997) that consist of exhaustive search algorithm, the baby-step giant-step algorithm, Pollard's rho algorithm, Pohlig-Hellman algorithm, and index-calculus algorithm. These algorithms are explorated to be used in discrete logarithm problem over finite field GF(3m ). The exploration also produces some algorithms, i.e. naif negative algorithm, baby-step mother-step algorithm, baby-step mother free-step algorithm, and baby-step free-step algorithm. All algorithms implemented using Maple 11. The Pohlig-Hellman and baby-step giant-step algorithms are efficient enough to be used in discrete logarithm problem over finite field GF(3m ) for m < 20.
