The path finding optimization is the most widely discussed issues in the informatics scope. This was related to the increased needs of the transportation, distribution and industry. The method for solving search problems for the shortest path can be done using two methods, namely the conventional method and the heuristic method. The conventional method uses a mathematical approach that is easy to understand, but the search results require a relatively long time. In order for search time to be faster, a heuristic approach is needed, although it requires more parameters. A-star algorithm is a heuristic route search method that is very effective in finding the shortest route. In this study a web-based application was developed by integrating the A-star algorithm to find the location of rare plants in the conservation area. As for determining the distance between the coordinates of the plant using haversine formula. This application is very important because of the large number of plants and the limited guidance of researchers in finding the location of rare plants in conservation areas. The guide is presented in the form of an easy-to-understand graph accompanied by information about the plants sought.

Saat ini teknik kriptografi Hill Cipher telah diimplementasikan untuk beberapa aplikasi. Dalam implementasinya ada saja kesalahan atau kecerobohan seperti kunci matriks yang digunakan pada proses enkripsi hilang karena tidak disimpan atau bahkan lupa. Oleh sebab itu diperlukan teknik kriptanalisis untuk mendapatkan kembali kunci yang hilang tersebut. Teknik kriptanalisis pada kriptografi Hill Cipher yang telah diketahui adalah dengan menggunakan persamaan linier dan menggunakan perkalian matriks. Pada persamaan linier, nilai dari masing-masing variabel matriks kunci dapat diketahui, namun proses pencarian nilai pada tiap variabel tersebut tidak dapat dilakukan dalam waktu yang singkat. Sedangkan pada perkalian matriks, proses pencarian variabel matriks kunci hanya dapat dilakukan jika matriks yang merepresentasikan plaintext memiliki invers atau nilai determinannya sama dengan satu. Nilai determinan yang didapatkan dari suatu matriks dapat dioperasikan untuk mencari nilai suatu variabel dari operasi aljabar linear yang telah direpresentasikan kedalam bentuk matriks. Masing-masing variabel tersebut dapat melakukan proses pencarian determinan secara bersamaan. Dalam penelitian ini penulis akan mengembangkan suatu sistem untuk mencari nilai pada variabel matriks kunci berdasarkan perhitungan determinan matriks yang dikembangkan menggunakan paradigma System Development Life Cycle (SDLC) Waterfall dan diimplementasikan pada sistem operasi berbasis Android.

The limited knowledge possessed by gouramy cultivators on diseases that attack gouramy has become a problem and obstacle in the effort of hatchery and enlargement of gouramy and the lack of experts in gouramy to provide counseling about gouramy diseases, so it is necessary to develop expert system applications aimed at a forum for consultation with experts, diagnosing gouramy disease and providing solutions to prevent diseases of gouramy. In the expert system there are several inference machines that can be used, one of them is using dempster shafers which are mathematical theories for proof based on belief functions and plausible reasoning. Used to calculate the probability of an event obtained from a combination of separate pieces of information (facts). In this study an expert system for diagnosing disease in gouramy using a dempster shafer inference machine resulted in a calculation of the level of confidence in carp disease at the highest 99.85% in Red Disease (Motile Aeromonas Septocemia) and at least 90% in white spot disease (White spot ).

Cattle are the livestock of the Bovinae family and subfamily Bovidae. They have been raised for beef and dairy products. Nowadays, beef production does not meet national needs. This is influenced by several factors. One of them is the farming pattern. However, knowledge about cattle farming is still scattered and unstructured. Knowledge Management System (KMS) offers a knowledge system that can be used to create, collect, store, maintain and disseminate knowledge. In this study, KMS for cattle farming has been implemented using the Knowledge Management System Life Cycle (KMSLC) method. The research results are web-based applications regarding cattle farming management that have been tested by experts and users, with the average test results declared good. The features possessed by this KMS application are knowledge capture, knowledge sharing, and knowledge application systems so that they can share knowledge between one user and another. In addition, this application is equipped with a discussion forum that can serve as a place to interact with fellow users or with experts.
