Therefore, an information system is necessary to record, report conditions, and display the current location of items directly. An Android-based application system is vulnerable to spoofing, such as fake GPS. The application is used to falsify the coordinates of digital map locations. This research aims to develop a common tracking system and prevent Fake GPS by employing the System Development Life Cycle method, consisting of several stages, i.e., planning, analysis, design, implementation, testing, and maintenance. In this research, a prototype of the tracker tool and its information system were made. It used an RFID Smart Card for courier identity authentication and a GPS module to track position information on a digital map. RFID and GPS were controlled using the ESP32. Furthermore, the Website served as an information system to read and create a QR Code to identify the goods carried. It received data from the RFID Smart Card and GPS, stored it in the Database, and displayed it online. The test results indicated that the tracker prototype succeeded in sending location data throughout the test and gained an average distance of 6.82 meters, which was different from a commercial GPS device. It had a delay of 268.5 seconds when the location was first read. The tracker prototype had an average power consumption of 1.5 watts, an average battery life of 2 hours, 28 minutes, and 40 seconds, as well as an average battery deficiency of 36.79%. In conclusion, the system test was successful.

The motive for consuming in Islam is basically mashlahah, needs and obligations. Satisfaction of a Muslim is not based on market more or less items that can be consumed, but based on how religious values are obtained from what it does. In the teachings of the Islamic religion for the purpose of consumption is the biggest maslahah, so that he can achieve victory in duina and hereafter. Satisfaction in Islam includes consumer satisfaction and creative satisfaction, consumer satisfaction will produce the ready creation of satisfaction, because the consumption made by a Muslim will give his physical strength, so he can be more creative. To measure the satisfaction of a Muslim we can use the concept of conventional utilities.

Big tasks such as coral reef exploration, oil refineries, underwater monitoring, and sea accident rescue are carried out by such technology. ROV or unmanned submarines have 6 degrees of freedom, but for diving it requires only 3 movements, that is, surge, heave, and pitch motions. In its operation, the ROV requires a navigation system in the form of estimation of the ROV position under diving conditions. In this study, two methods were used to estimate the ROV position under diving conditions, that is, the H-infinity method and the Ensemble Kalman Filter (EnKF). Both methods proved reliable on other platforms. The simulation results in this study showed that the EnKF method was more accurate than the H-Infinity method. The H-Infinity method had an accuracy of around 87%, while the EnKF method reached an accurate of 99 %.

So, blood transfusion health services include planning and preservation of blood donors, blood providers, blood distribution, and medical actions for giving blood to patients for the purpose of curing disease and restoring health. The blood distribution to hospitals by the PMI Blood Donor Unit is a pickup system if carried out in the vicinity of the PMI concerned. Therefore, the request for blood by the recipient to the hospital or the PMI Blood Donor Unit takes before the hospital makes a blood request to the PMI Blood Donor Unit. The hospital blood bank makes an offer to the patient or the patient's family in need for blood. whereas the hospital blood bank is a service unit in the hospital responsible for the availability of blood for safe, good quality, and sufficient transfusion in supporting health services in hospitals and other health care facilities. One way to reduce the risk of a shortage and excess of blood needs is by applying an estimation algorithm to determine future blood needs and supplies. The objective of this paper is to apply an estimation algorithm to estimate the supply of Fresh Frozen Plasma (FFP) at PMI Gresik, whereas FFP is a yellowish blood component. FFP is a blood product processed from whole blood. This paper used a reliable estimation method, that is, the Ensemble Kalman Filter method and the Extended Kalman Filter method. The simulation results show that both methods had good accuracy, but the EnKF method was more accurate with an error of about 4%.

Indonesia itself, which is a country of archipelago, covers air area of its largest territory, followed by sea area and land area. Logically, the existence of missile defense equipment (the main weapon system) or precisely the type of long-range missile is acceptable to support the defense and security of the Republic of Indonesia, but its consequences to be operated in the territory of Indonesia itself, in case of an occufanct of an error in targeting the target, will fall on of harm to its own national territory. Therefore, trajectory estimation for guided missiles is the basic requirement for guided missiles to be aimed at the precise targets. The trajectory is used as a guide to direct that the missile reach the target by following the given path. To maintain the accuracy of the trajectory continuously, the missile trajectory estimation was made by using Unscent...
