Judul: Model pengembangan minapolitan berbasis budidaya laut di Kabupaten Kupang
Abstrak: This research was conducted in Kupang regency, East Nusa Tenggara. The main purpose of this study was to develop a minapolitan model of regional development in the Kupang regency - Nusa Tenggara in order to improve the living standards of social and economic life of society. To achieve the main objective, then there are some activities that need to be done as a special purpose, among others: 1) Analyze the potential, level of development, and sustainability for the development of minapolitan in Kupang regency, and 2) Build a sustainable development model of minapolitan area in Kupang regency. The study was conducted in March 2011 to August 2011 is located in Semau subregency, West Kupang sub-regency and Sulamu sub-regency. Data analysis include: (1) Identification of potential areas comprising: spatial analysis (GIS) with Arc GIS Version 9, the land suitability analysis, carrying capacity analysis, financial analysis; (2) Valuing the level of development consisting of the typology analysis, principal component analysis (PCA), cluster analysis, scalogram analysis, centrality analysis, methods comparison of exponential (MPE), analysis hierarchy process (AHP) with criterium decision plus (CDP), structural interpretative modeling analysis (ISM); (3) Sustainability status of the region by using analysis of multidimensional scaling (MDS) called Rap-MINAKU, monte carlo analysis and prospective analysis; and (4) Building a development of marine culture-based minapolitan model with analysis of dynamic systems with powersim constructor version 2.5d. The results suggest that seaweed farming has a profitable business opportunities in the development of minapolitan in Kupang regency that is currently in the category of the strata pre-minapolitan II region seen from the completeness of the facilities owned by each village, there are six villages with a more advanced stage of development, 7 villages with the average development level, and 11 villages with a level of development lags. In a multidimensional in Kupang regency, aquaculture region sustained quite sensitive to 18 attributes that affect the increase sustainable index. The analysis showed each component of the dynamic system show a tendency to form a positive growth curve (positive growth) following an exponential curve. Policy direction in the development of marine culture in Kupang regency is the development of seaweed farming. Strategy should be to establish a production center and its hinterland with complete facilities and infrastructure needed, move the commodity diversification of seaweed processing in domestic industry, increase production of seaweed in minapolitan area through extension to the maximum limit, increasing the capacity of farmers, increase coordination and good partnerships in all relevant stakeholders, and improve the status of sustainability for the development of minapolitan in Kupang regency in the short term, medium term and long-term.

Judul: Model Integrasi dalam Pengembangan Minapolitan Perikanan Tangkap di Palabuhanratu, Kabupaten Sukabumi, Jawa Barat
Abstrak: Palabuhanratu Archipelagic Fishing Port has been established as the field project of capture fisheries minapolitan. Minapolitan development will be effective if managed in an integrated model. This research was aimed to: 1) identify the implementation problems, 2) formulate the integrated model based on market integration, supply chain and institutional partnerships, 3) formulate strategies and benchmarks of the integrated model in developing capture fisheries minapolitan at Palabuhanratu. System approach, descriptive analysis, SWOT and balanced scorecard were used for data analysis. The result found that the implementation problems of capture fisheries minapolitan at Palabuhanratu were fishermen poverty, declined in fish stocks, and conflicts in the utilization of coastal and marine areas. Tuna and hairtail market at Palabuhanratu were highly integrated for both local and export markets. The vertical integration process occurred among fishermen, vessel owners, and the company. The integration of minapolitan institutional can be done through participation in a harmonious and mutual need between government, private sector, and intellectual. Strategies for the successfull implementations in the minapolitan model were 1) optimization of tuna and hairtail product, 2) improving facilities and infrastructure of transportation and fishing port, 3) cooperation of minapolitan business partnerships, 4) improving performance of fishing port institutional, 5) the fisheries industrialization, 6) sustainable fisheries development, 7) building win-win partnerships between fisherman, vessel owners and exporter, 8) building a collective consciousness to remain committed and consistent in developing minapolitan. Balanced scorecard analysis produced 16 successfull factors (benchmarks) and 13 programs that should be done to achieve strategic goals.

Judul: Kombinasi algoritma sha 1 dan algoritma rsa untuk membentuk tanda tangan digital
Abstrak: Tanda tangan digital termasuk ke dalam teknik kriptografi yang memanfaatkan teknologi kunci publik (enkripsi asimetris). Tanda tangan digital dapat dibuat dengan mengkombinasikan teknik hashing (untuk membentuk message digest dari pesan asli) dan enkripsi asimetris (untuk membentuk kunci publik dan kunci privat). Teknik hashing yang digunakan adalah teknik rashing satu arah dengan menggunakan algoritma SHA 1, sedangkan algoritma RSA digunakan untuk enkripsi asimetris Tulisan ini bertujuan untuk mempelajari, menganalisis, dan mengimplementasikan pembentukan dan verifikasi tanda tangan digital menggunakan dua metode, yaitu dengan mengkombinasikan algoritma SHA 1 dan algoritma RSA dan dengan menggunakan algoritma RSA saja. Analisis yang dilakukan pada kedua algoritma ini meliputi analisis algoritma, dan analisis hasil implementasi. Analisis terhadap algoritma SHA | menunjukkan bahwa algoritma ini memiliki kompleksitas O(n) untuk kasus terburuk. Sedangkan untuk pembentukan kunci publik dan kunci privat dengan algoritma RSA diperlukan beberapa algoritma pendukung, yaitu algoritma Miller Rabin, Witness, Euclid, dan Extended Euclid. Semua algoritma pendukung tersebut memiliki kompleksitas waktu yang sama, yaitu O(k), dengan adalah panjang representasi bit bilangan bulat. Kompleksitas waktu yang didapatkan untuk proses pembentukan tanda tangan digital dengan kedua metode ini adalah sama yaitu O(nk). Untuk proses verifikasi, kompleksitas waktu yang didapatkan dengan menggunakan kombinasi dua algoritma adalah O(1 + k) dan untuk algoritma RSA adalah O(n + k). Pada proses pembentukan tanda tangan digital menggunakan kombinasi dua algoritma yang ditandatangani adalah message digest yang dihasilkan oleh algoritma SHA 1, sedangkan pada algoritma RSA yang ditandatangani adalah pesan itu sendiri. Dari hasil implementasi didapatkan untuk proses pembentukan tanda tangan digital menggunakan kombinasi dua algoritma lebih cepat dibandingkan dengan menggunakan algoritma RSA saja untuk file-file yang berukuran besar, dst
