Abstract

The Indonesian Red Cross (PMI) plays a very important role in providing the information needed by the community. One of the main information needed by the community is the blood supply. To obtain information related to the blood supply at PMI, there is a procedure that must be done in advance by the patient's family ie sending a form and blood sample to a blood bank at the hospital or to the laboratory of the PMI Transfusion and Blood Donor Unit (UTDD) in the City. However, the availability of blood stocks in the PMI UTDD is often not sufficient for blood needs and compulsory family families of patients who should look for blood donors that match the blood type of the patient. This certainly does not make it easy for the patient's family. In addition, families of patients who are in need of blood is also not easy to find blood donors who are located closest to the hospital. The shortest path search has several problems, but the main problem is finding the shortest route, of course, looking for the shortest possible route or path. However, for its implementation, this issue can be expanded more broadly among others to find the minimum cost, etc. In this research will be analyzed the performance of software to find information of the nearest blood donor with two different method, that is method of Greedy Best First Search and Dijkstra, besides analyzing the performance of the algorithm, this research also can know the percentage of similarity of output from searching the closest distance of both algortima , so it can know how many percent level of similarity of both algorithm. The result of the Dijkstra algorithm's order of growth value is better than the Greedy Best First Search method with a value of O (n ^ 2) and the similarity of the results of the two algorithms is 75%.

Abstract

There are three elements of security, which are data confidentiality, data integrity, and data availability. This research focuses data confidentiality on NodeMCU microcontroller device in an IoT environment. Relatively small NodeMCU processor and dynamic memory becomes a challenge in fulfilling the data confidentiality. Lizard stream cipher algorithm is implemented on NodeMCU. The JSON (JavaScript Object Notation) data will be encrypted into a cipher text using the Lizard algorithm keystream before being sent to the database server over the wireless wifi network. On the server side, the data will be decrypted into its original form and stored into the database. The process of sending data uses the REST (Representational State Transfer) web service architecture. There are four parts of testing to ensure the system has been running well, that is test vector validation testing, functional testing, time and memory performance testing, and security testing. The 216 and 352 bit keystream generated on NodeMCU devices takes 0.01 seconds and 3.4% of total dynamic memory, while encrypting 216 and 352 bits plain text takes 0.02 and 0.04 seconds with 0.3% of total dynamic memory. Implementation of Lizard algorithm has successfully guaranteed the data confidentiality.

Abstract

Islamic law establishes inheritance rules with a very fair form. In it is the right of ownership of property for the heirs, both men and women in a fair way. Islamic law also establishes the right of shifting of ownership of a person after passing away to his heirs from all his relatives and nasabs, without distinction between men and women, young and old alike. But in its implementation, for the Islamic community itself, most of the determination and calculation of inheritance is done in a way that is not in accordance with the prevailing law of inheritance of Islam that often leads to conflict. In solving the limited problem of experts regarding inheritance law, it is necessary to design an application that can help solve the problem according to Islamic law. This thesis provides a more accurate decision using forward chaining and dempster-shafer methods based on an expert's trust. In the Dempster-Shafer theory there is a Frame of Discernment denoted by θ. This frame is the universe of speech from a set of hypotheses θ = {A, B, D, E}. The goal is to relate the trust size of the elements θ. Not all evidences directly support each element. Based on the testing of this system that is equal to 92.67% which means this system can run well because the results of the system close to the similarity with the fact of the actual field.
