Implementasi Pengamanan Data dan Informasi dengan Metode Steganografi LSB dan Algoritma Kriptografi AES

Security and confidentiality are two important aspects of data communications. In maintaining the security and confidentiality of an important message to be delivered, the first message is encrypted and hidden into a medium. Media used in this study is a digital image with a color depth of 24 bits. This research aims to develop a system that can be used to enhance the security of data in the form of important and confidential messages. Cryptographic algorithms used for encryption was aes algorithm and steganography by modifying the method of least significant bit (LSB) which was used to save the message in the image. Modified LSB used in this research was by inserting bits of the ciphertext into a diagonal matrix of pixel color components in the image. The system was developed using the programming language c #. Tests conducted in this study were to look at aspects of imperceptibility and recovery of the method modified LSB. This study confirms that the combination of the aes algorithm and modified LSB can be used to improve data security

Pengembangan Budaya Mutu Dalam Meningkatkan Kualitas Madrasah Di Madrasah Ibtidaiyyah Negeri Kota Bandar Lampung

DEVELOPING A QUALITY CULTURE IN IMPROVING QUALITY OF MADRASAH (Studies in MIN as Bandar Lampung): Quality is important in human life, both individually, comunally, or socially.

Strategy of Sustainable Waste Management in Port of Arar, Sorong

Arar Port of Sorong is a developing port and located in an exclusive economic area. It has a potency to produce waste and higher possibility of littering. This study aims to formulate a sustainable waste management strategy at Arar Port of Sorong. In this study interviewed five expert experts selected purposively with the help of an individual questionnaire for analytical hierarchy process (AHP) purposes. The data obtained were analyzed by AHP using expert choice software 2000. The results showed that three main strategies need to be done to manage the waste in Port Arar Sorong District become sustainable. The first approach is to make the waste processing and litter into daily habituation from the community. The second strategy is to implementing zero waste technology. The last policy is enforcing the law

Potensi Dan Pemanfaatan Limbah Susu Bubuk Untuk Fortifikasi Kompos Pada Pertanian Sayur Organik

Composting can be use as one of the alternatives solution to managing solid waste. The purposes of this research are (1) Knowing the initial description of the potential milk powder and waste management through surveys (2) Knowing the influence of the concentration of Waste Water Treatment Process (WWTP) sludge as waste decomposers and fortification dose of milk powder. Indicators used are compost quality, yield and growth of leafy vegetables and improvement of soil fertility. This research used 2 factors and 3 replications. Factor A: WWTP sludge concentrations (0%, 10% and 20%) and Factor B: dose fortification of milk wastes powder (0%, 10% , 20% and 30%). Complete factorial designs were used as a tools in this research. The survey shows that the average distributor waste is 2,35% per month. Waste management of milk powder solid waste usually done by burn it with diesel fuel or gasoline. In the industries 68,7% of waste are damaged waste that burn in incinerator. In the quality of compost show that interaction between A and B havehighly significant effect in total of N. The result of fortified compost has met quality standards microbe well as heavy metals. The aplication of fortified compost was increase soil labile C organic. Factor B have significant effect in the width of leaves and yield of vegetable. In the soil fertility show that the interaction between A and B have significant effect in total of Nand K2O .The best combination in this research is A3B4 (20 % WWTP sludge and dosage fortification solid waste 30%dry basis)
