Dari hasil pengujian algoritme dapat dibuktikan bahwa sistem mampu menentukan jarak terpendek dari titik awal yang ditentukan pengguna menuju titik tujuan wisatanya. Dari pengujian blackbox didapat hasil bahwa fungional sistem memiliki kinerja yang baik. AbstractToboali City is the capital of South Bangka Regency which has become a new tourist destination because of its beauty and supported by local government policies. Therefore tourism facilities continue to be developed to date. However, many tourists from other regions experience difficulties on their way to tourist destinations in Toboali City. This is because they do not know the geographical location of Toboali City. The difficulty experienced by these tourists is in terms of knowing and determining the path to be traveled to the destination. For this reason, a geographic information system based on the web was made and equipped with the shortest distance determination function using the Dijkstra algorithm to be able to reach tourist destinations faster. The system is designed web-based so that more people use it. In this study also discussed how the manual calculation of the Dijkstra algorithm, in addition to proof of calculations, is also given in the form of a case in determining the shortest distance in one corner of the city of Toboali. The results of the research in the form of the Toboali City tourism information system that can determine the shortest distance to the tourist location. From the algorithm test results it can be proven that the system is able to determine the shortest distance from the user-specified starting point to the destination point of the tour. From the blackbox testing, the results show that functional systems have good performance.

Improved security of short message services (SMS) can be obtained using cryptographic methods, both symmetric and asymmetric, but must remain efficient. This paper aims to study the performance and efficiency of the symmetric crypto of AES-128 and asymmetric crypto of RSA with message compression in securing SMS messages. The ciphertext of RSA and AES were compressed using the Huffman algorithm. The average AES encryption time for each character is faster than RSA, which is 5.8 and 24.7 ms/character for AES and AES+Huffman encryption and 8.7 and 45.8 ms/character for RSA and RSA+Huffman, from messages with 15, 30, 60, and 90 characters. AES decryption time is also faster, which is 27.2 ms/character compared to 47.6 ms/character in RSA. Huffman compression produces an average efficiency of 24.8 % for the RSA algorithm, better than 17.35 % of AES efficiency for plaintext of 1, 16, 45, and 88 characters.

Nowadays, we can find Lamongan Restaurants wherever we are. Almost every street there is one Lamongan Restaurant. One of these types of UMKM is so popular among the public. This happened because the food that offered was acceptable and became a favorite for the public, as well as what happened in Bangka Belitung Province. However, most UMKM still uses manual methods for bookkeeping and transactions. Problems arise when many customers come to place to order, as well as those who want to make payments must wait for the manual calculation. Besides, manual bookkeeping can still cause errors in the calculation. To solve this problem, an integrated management system is proposed throughout the Province of Bangka Belitung. That way, every UMKM can easily do bookkeeping and transactions, besides that the government can also easily to monitor, record, and access the information reports from UMKM. This study uses a prototype development model. The results are the implementation of the integrated management system for Lamongan Restaurants in Bangka Belitung province based on the web and Android.Keywords—Management Information System, Integration, UMKM Lamongan Restaurant, Android, Web ServerDOI: 10.5281/zenodo.2010359

The number of pharmacies in the Pangkalpinang City has increased rapidly. This is directly proportional to the needs of the people of Pangkalpinang City to fulfill the health needs, buy medicine or divert doctor's prescriptions. This is a debate for people who do not know the location of pharmacies in this city. Practically, people can just go to a pharmacy with a location that far from user location, even though there is a pharmacy near the user. This is because there is no pharmacy information location in the Pangkalpinang City. To solve this problem, proposed a system that can display the location of all pharmacies in the Pangkalpinang City. In addition, the system can search the shortest path from the user's location to the nearest pharmacy location around using the A * algorithm. This algorithm was chosen because its advantages that are able to produce optimal solutions according to the expected heuristic functions. The results of the testing are that the system can optimize and be able to search the shortest path from the user's location to the nearest pharmacy.
