Judul: Pengaruh Kemitraan Pabrik Gula Karangsuwung Kabupaten Cirebon terhadap Tingkat Kesejahteraan Petani Tebu
Abstrak: Partnerships in plantation is a mutually beneficial relationship, mutual respect, mutual responsibility, mutually reinforcing, and interdependence among firms with planters. However, the trend of inequality and domination in partnership creates dependency either party in this case the farmers against the company. Dependency is what makes a strong control of the farmers so that farmers in decision-making independence of farming is low. The purpose of this study to analyze the pattern of partnership that exists between PG Karangsuwung with sugarcane farmers, as well as determine the level of independence of the partner farmers trying to farm and farmer's welfare. Based on the results of the study showed that the degree of independence of sugarcane farmers partner does most of the still relatively low, but when seen from the welfare of the majority of already high. This is because the degree of independence is less direct effect on the level of well-being, there are other more influential factors such as the size of land holdings.

Judul: The Influence of Land Size and Performance of Partnership Assistance on Sugarcane Farming Income (Case Study of PG Jatitujuh Partner Farmers).
Abstrak: Pabrik Gula Jatitujuh menjalin kemitraan dengan petani di Desa Sumber Kulon. Petani mengelola lahan dengan berbagai luasan. Adanya ketentuan dan pendampingan kemitraan menyebabkan perbedaan pendapatan pada pendapatan petani tebu. Oleh karena itu, penelitian ini bertujuan untuk menganalisis pengaruh luas lahan dan kinerja pendampingan kemitraan terhadap pendapatan. Data yang digunakan adalah data sekunder tahun 2022. Metode analisis yang digunakan yaitu analisis pendapatan, uji anova, analisis regresi linear berganda, analisis standar deviasi, dan koefisien variasi. Hasil penelitian menunjukan bahwa terdapat perbedaan pendapatan pada kelompok luas lahan. Selain itu, kemitraan yang dijalankan oleh PG belum sesuai dengan SOP (Standard Operating Procedure) dari kementrian pertanian., Jatitujuh Sugar Factory has established partnerships with farmers in Sumber Kulon Village. Farmers manage lands of various sizes. The existence of partnership provisions and assistance results in differences in income for sugarcane farmers. Therefore, this study aims to analyze the effect of land area and partnership assistance performance on income. The data used are secondary data from 2022. The analysis methods used are income analysis, ANOVA test, multiple linear regression analysis, standard deviation, and coefficient of variation. The results of the study show that there are differences in income among different land area groups. In addition, the partnerships run by the sugar factory are not in accordance with the Standard Operating Procedure (SOP) of the Ministry of Agriculture.

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.
