MARITIME CRYPTOLOGY Intan Muchtadi Alamsyah
Pattimura Proceeding 2017: Proceedings of the 3rd International Seminar of Basic Science
Publisher : Pattimura University

Maritime has special needs for information security, including the protection of classified information. As written in â€œCryptographyâ€™s Role in Securing the Information Societyâ€: â€˜Cryptography provides important capabilities that can help deal with the vulnerabilities of electronic information. Cryptography can help to assure the integrity of data, to authenticate the identity of specific parties, to prevent individuals from plausibly denying that they have signed something, and to preserve the confidentiality of information that may have improperly come into the possession of unauthorized parties [Dam and Lin, 1996]. Elliptic Curve Cryptography (ECC) was first introduced by Neal Koblitz and Victor Miller ([Koblitz1987],[Miller1985]). They independently introduced the elliptic curve to design a public-key cryptography. Compared to other cryptography method, it has several advantages: its arithmetic operations are spesific and can not be predicted, it offers smaller key length for the same security level compared to other method and its operations have many layers and combinations. ECC relies on the security level of the discrete logarithm problem called Elliptic Curve Discrete Logarithm Problem (ECDLP) [Hankerson et al, 2004].

High worldwide demand for energy, souring prices of petroleum, and concern over global climate change has led to resurgence in the development of alternative energy that can displace fossil transportation fuel. Biomass is one of the important renewable sources for securing future energy supply, production of fine chemicals and high value biodegradable polymers, and sustainable development. Recently, efforts have been devoted to the conversion of lignocellulosic materials into fine chemicals, biopolymers, and biofuels. Attempts to transfer biomass to produce industrially useful polymers and fine-chemicals by traditional biotechnological approaches have obtained only very limited success. An effective biomass conversion requires the interdisciplinary research field which is a unique combination of biotechnology, chemistry, materials science and engineering, and may ultimately lead to cheap and effective processes for conversion of biomass into useful products such as fine chemicals, biopolymers, and biofuels.

The Li0.5La0.5TiO3 and LiFePO4/C has been prepared using sol-gel method for its interface analysis towards its application for all solid state assembly. The LiFePO4cathode material and Li0.5La0.5TiO3 solid electrolyte has been individually tested for its electrochemical reversibility. The thin film battery assembly shows severe capacity fading, which results in electrochemically non active with the chosen anode materials. In order to verify the electrochemical activity and interaction of Li0.5La0.5TiO3-LiFePO4/C interface the mixture has been tested for its electrochemical reversibility. The Li0.5La0.5TiO3-LiFePO4/C interface exhibits well resolved oxidation-reduction hype which verifies its suitability towards all solid state assemblies.

Publisher : Pattimura University

A weighted non-preemptive multi-criteria model is built to optimize the distribution of students into academic departments of a faculty by taking into account the limits of space capacity, financial allocation, the number of instructors and affirmative action quotas. Each constraint has a weight attached. This model is applied to the Faculty of Science and Technology, Universiti Kebangsaan Malaysia. The successful application demonstrates the ability of the weighted non-preemptive model to comply with the student intake requirement and constraints of academic departments in the faculty.

The content of secondary metabolites of seaweed as an antibacterial, antiviral, antifungal and sitotastik have great potential as a source of cure various diseases. Padina sp is one of brown algae which is potential to be a natural antibacterial agent. This research aims to determine the inhibitory potency of Padina sp. extract on the growth of Vibrio parahaemolyticus, Staphylococcus aureus, Escherichia coli, and Salmonella thypimirium bacterial. The extraction Padina sp using methanol as the solvent while the treated samples dilution of 0, 5, 10 and 50. Then measuring the inhibition by paper disc methods. Result showed that the diameter methanol extract of seaweed Padina sp. against bacterial the growth inhibition of E. coli each 26.5 mm with the very strong barriers response and 17.5 mm were classified as strong; on the growth of Salmonella thypimirium bacteria by 19 mm with a response barriers that were moderate but not have inhibitory effect on the growth of Vibrio parahaemolyticus and Staphylococcus aureus bacterial.

Publisher : Pattimura University

This study was conducted to analyze the number of microbes on marinated scallops Gafrarium tumidum during cold storage. The results showed that the number of microbes on the scallops marinated products G. tumidum ranged from1.1 x 102 - 7.4 x 102 cfu/g, so that they meet the SNI 01-2725-1992, the maximum limit of microbial contamination is 5.0 x 105 cfu/g. Total plate count (TPC) value marinated scallops with storage time to 14 days is below the maximum limit is set, so that the marinated of shellfish products G. tumidum still meet microbiological standards and suitable for consumption.

As a good source of protein and other nutrition that useful for human growth, fish is categorized as perishable food that decaying quickly without good handling. In order to prevent the fish decay and to maintain the quality and freshness of the fish as long as possible, it is need good handling and storage sanitation. Chilling and freezing are the most common technology applied to prolong the shelf life of fresh fish. Chilling is one method of handling that most widely used because it can be practiced easily and quickly. This study aimed to determine the changes in the quality of fresh skipjack (Katsuwonus pelamis) during chilled storage. Parameters as quality indicator measured were total plate count (TPC), total volatile bases (TVB), and pH. Chilled storage were 0, 2and 4days. TPC of fresh skipjack during chilled storage at 0, 2 and 4 days were 1.08 x 102, 8.11 x 102 and 1.06 x 103 cfu/g, respectively. TVB of fresh skipjack during chilled storage at 0, 2 and 4 days were 9.33, 16.00 and 20.00 mgN/100g, respectively. The pH of fresh skipjack during chilled storage at 0, 2 and 4 days was 4.7, 4.8 and 5.4, respectively
