Controlling birth is closely related to the use of contraceptives for their partners. However, the problem they often face is that they struggle to choose an effective contraceptive that suits their body condition. This is not only caused by the limited methods available but also because they do not know the requirements and safety of these contraceptive methods. This study aims to implement and analyze the comparison of the Weight Product (WP) method and the Simple Additive Weighting (SAW) method in a web-based contraceptive selection decision-making system. This system can work well in determining the right contraception for a married couple. In the time testing process, the implementation of the SAW method has an average execution time of 1.8784 s while the WP method has an average execution time of 0.3340 s. Based on the research results, the WP method is slightly faster than the SAW method in carrying out the calculation process in the decision support system for the selection of contraceptives.Â

The study aims to design decision support system using triangular fuzzy number approach in Analytic Hierarchy Process method. The Analytic Hierarchy Process (AHP) is one of the decision support system method which controls experiences and intuition but critical at coupled comparative scales because it uses crisp. A triangular fuzzy number is used to approach AHP scale so as to obtain more fexible value of coupled comparison. The triangular fuzzy number-AHP method uses analysissynthetic extent in the priority processing implemented on ranking cases of potential acceptors of scholarship of PPA and BBM in Technic Faculty Tadulako University of Palu. The result is the average of mismatch between the result by triangular fuzzynumber-AHP method and the result of manual work which are 23.93% of the PPA scholarship and 27,35% of the BBM scholarship.

Short Message Service (SMS) still has security problems with attempts to steal messages, intercept messages, hijack messages by parties who are not responsible for obtaining information. Cryptography is the science of maintaining the confidentiality of information from aspects that can threaten information security with certain mathematical algorithms and techniques. The Luc algorithm is a public key cryptographic algorithm that was developed using the lucas function. This study aims to implement the Luc algorithm on an Android-based SMS security application in the National Narcotics Agency of Central Sulawesi Province to maintain privacy in communication between the sender and recipient of the message. This application was created using an Android studio developer with the Java programming language. Based on the results of the first test for a sample of plain messages in the word KOTA PALU that uses public key 13 produces the message cipher P=Se!CQa. The second test result for the message sample on the word KOTA PALU that uses public key 29 generates the AD*`_$(NQ cipher message
