Judul: The Relationship between PT Tirta Investama Subang's CSR Program Performance and the Community's Standard of Living (The Case of the Banceuy Traditional Village, Sanca Village, Ciater District, Subang Regency, West Java Province).
Abstrak: Program CSR dilaksanakan dalam pemberdayaan masyarakat, harapannya program CSR meningkatkan taraf hidup masyarakat. Salah satu perusahaan yang melaksanakan program CSR adalah PT Tirta Investama Subang. Tujuan penelitian menganalisis kinerja program CSR, menganalisis taraf hidup masyarakat setelah adanya program CSR berdasarkan lapisan sosial dan menganalisis hubungan kinerja program CSR dengan taraf hidup masyarakat, dengan pendekatan mix methods. Tahap kuantitatif diperoleh dengan metode survei menggunakan kuesioner, sedangkan tahap kualitatif dilakukan dengan wawancara mendalam. Jumlah responden penelitian 60 responden ditentukan secara purposive. Hasil penelitian menunjukan hubungan kinerja program CSR dengan taraf hidup masyarakat di Kampung Adat Banceuy memiliki hubungan yang signifikan pada kategori moderat atau cukup kuat antara kedua variabel artinya tingkat kinerja program CSR memiliki dampak cukup kuat terhadap taraf hidup masyarakat di Kampung Adat Banceuy., The CSR program is implemented in community empowerment, it is hoped that the CSR program will improve people's lives. One of the companies implementing CSR programs is PT Tirta Investama Subang. The aim of the research is to analyze the performance of the CSR program, to analyze the standard of living of the community after the CSR program is based on social strata and to analyze the relationship between the performance of the CSR program and the standard of living of the community, using a mix methods approach. The quantitative stage was obtained by survey method using a questionnaire, while the qualitative stage was carried out by in-depth interviews. The number of research respondents was 60 respondents determined purposively. The results showed that the relationship between the performance of the CSR program and the standard of living of the people in Banceuy Traditional Village had a significant relationship in the moderate category or quite strong between the two variables, meaning that the level of performance of the CSR program had a fairly strong impact on the standard of living of the people in Banceuy Traditional Village.

Judul: The Correlation between the Success of Corporate Social Responsibility Program with Community Welfare Level
Abstrak: Program Corporate Social Responsibility (CSR) yang dirancang oleh suatu perusahaan dengan harapan memuat kebutuhan dasar masyarakat sehingga baik masyarakat maupun perusahaan dapat memperoleh kebermanfaatan yang sama. Tujuan dari penelitian ini adalah untuk mengetahui hubungan variabel efektivitas komunikasi pendamping program dengan keberhasilan CSR dalam tingkat kesejahteraan masyarakat. Penelitian ini dilakukan pada salah satu binaan PT Astra Daihatsu Motor yaitu Kampung Guyub Rukun Desa Sukaluyu, Kecamatan Telukjambe Timur, Kabupaten Karawang, Jawa Barat. Metode yang digunakan dalam penelitian ini adalah kuantitatif yang didukung oleh data kualitatif. Data kuantitatif diolah menggunakan uji korelasi Rank Spearman dengan responden 30 orang. Hasil penelitian menunjukkan bahwa program KBA terbukti berhasil untuk meningkatkan kesejahteraan masyarakat seperti pada bidang lingkungan dengan pengolahan sampah dan bidang kesehatan dengan optimalisasi peranan posyandu. Hal ini terkategori signifikan dengan komunikasi pendamping program yang baik. Meskipun kondisi pandemi dan tidak memungkinkan tatap muka secara langsung namun dapat menjadi solusi dengan melakukan komunikasi secara daring. Kata kunci : CSR, kesejahteraan, komunikasi, The Corporate Social Responsibility (CSR) program designed by a company is expected to contain the basic needs of the community so that both the community and the company can get the same benefits. The purpose of this study was to determine the corelation between the effectiveness of program companion communication with the success of CSR in improving community welfare. This research was conducted at one of the fostered companies of PT Astra Daihatsu Motor, namely Kampung Berseri Astra Guyub Rukun, Sukaluyu Village, Telukjambe Timur District, Karawang Regency, West Java. The method used in this study is a quantitative method supported by qualitative data. Quantitative data was processed using the Spearman Rank correlation test with a total of 30 respodents. The results showed that the KBA program was proven to be successful in improving the welfare of the community, such as in the environmental sector with waste management and in the health sector by optimizing the role of the posyandu. This is categorized as significant with good program companion communication. Despite the pandemic conditions and not allowing face-to-face meetings, it can be a solution by communicating online.

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.
