Pada penelitian ini dikembangkan algoritma hibrid Extended Kalman Filter (EKF) dan Sistem Inferensi Fuzzy untuk mendapatkan hasil estimasi yang lebih akurat pada penjejakan target bermanuver. Logika Fuzzy telah digunakan untuk mengatur galat kovarian proses dan galat kovarian pengukuran dari proses EKF pada model sistem. Model state space yang digunakan untuk estimasi adalah model percepatan konstan, dan model pengukurannya adalah model radar. Hasil pengukuran sensor yang mengandung derau diestimasi menggunakan algoritma EKF. Kemudian galat kovarian yang dihasilkan dari proses EKF digunakan sebagai masukan pada Sistem Inferensi Fuzzy untuk koreksi berdasarkan ketidaksesuaian antara vektor inovasi dan kovarian inovasi. Hasil koreksi ini digunakan untuk mendapatkan gain Kalman yang optimal. Berdasarkan simulasi yang dilakukan menggunakan estimasi EKF dan Sistem Inferensi Fuzzy diperoleh peningkatan akurasi sebesar 59,97% dibandingkan dengan hasil pengukuran tanpa melakukan estimasi.In this paper the Extended Kalman Filter and the Fuzzy Inference System hybrid algorithm has developed to get more accurate estimation result for maneuvering target tracking. Fuzzy Logic has used to adjust the process covariance error and measurement covariance error of the Extended Kalman Filter process in the system model. The state space model used for estimation is a constant acceleration motion model, and the measurement model is a radar model. The measurement result of the sensor containing noise estimated using the Extended Kalman Filter (EKF) algorithm. Then, the covariance error resulting from the EKF process is used as input to the Fuzzy Inference System (FIS) for correction based on the mismatch between innovation vector and innovation covariance. The result of this correction used to obtain the optimal Kalman gain. The proposed system model leads to improved accuracy of 59.97% compared to measurement results without estimation in the simulation case.

Assessment of good government performance is characterized by the quality of its services to the community. One of the roles of the village as the lowest administrative level in a region is to serve the community in making letters. Management of outgoing mail in Desa Dunggala, Kecamatan Tapa, Kabupaten Bone Bolango is still done conventionally, namely by recording the letter number in the agenda book. This resulted in village officials experiencing difficulties in managing the correspondence archives if in the future a letter with a certain number was needed. This community service activities aimed at helping the village government in managing outgoing mail by designing information system for managing outgoing mail. The information system was built based on the web application, but in its application is still used offline or localhost, due to internet network constraints in the village office. A database system is used for data storage so that it is easy to search the letters that have been made. Then, the village officials has been trained to use the information system. The results obtained from this activity are the information system for managing outgoing mail and the training of village officials in using the application. This information system can be further developed by taking into account the needs that exist in the village.

Melayani masyarakat melalui surat menyurat merupakan salah satu tanggung jawab kecamatan atau desa yang merupakan penyelenggara pemerintahan tingkat terendah di daerah. Jika administrasi tidak dilakukan dengan benar, pembuatan surat di kelurahan akan menimbulkan masalah tersendiri. Evaluasi yang efektif atas kinerja pemerintah ditentukan oleh seberapa baik pemerintah melayani masyarakat. Tujuan dari kegiatan pengabdian ini adalah untuk membantu pemerintah dalam memberikan solusi pengelolaan surat keluar berbasis komputer, khusus untuk Desa Dunggala, Kecamatan Tapa, Kabupaten Bone-Bolango. Untuk menghemat waktu dan tenaga, desain aplikasi surat keluar ini akan mengotomatiskan format surat, tidak perlu memasukkan manusia untuk setiap surat yang dibutuhkan masyarakat atau warga kecamatan. Tujuan dari aplikasi ini adalah untuk memanfaatkan secara maksimal perangkat komputer desa yang saat ini hanya digunakan untuk menggantikan mesin tik manual. Aplikasi yang dikembangkan untuk berbasis web tetapi sebenarnya digunakan secara offline atau lokal, dengan maksud agar pengembangan di masa mendatang—jika memungkinkan—dapat dilakukan secara online. Program yang dibuat menyimpan datanya dalam database sistem, membuatnya mudah untuk menemukan huruf yang ditulis sebelumnya. Tersedianya program-program yang user-friendly yang mudah digunakan dan tidak memerlukan pengetahuan khusus merupakan salah satu hasil dari upaya ini. Peningkatan lebih lanjut dari aplikasi surat keluar ini dapat dilakukan dengan mempertimbangkan kebutuhan desa atau kecamatan. Serving the community through writing letters is one of the responsibilities of the sub-district or village, which is the lowest level government administration manager in the area. If administration is not done correctly, making letters in the kelurahan leads to its own set of issues. An effective evaluation of a government's performance is determined by how well it serves the community. The purpose of this service activity is to assist the government in delivering a computer-based outgoing mail management solution, specifically for Dunggala Village, Tapa District, Bone-Bolango Regency. In order to save time and effort, the outgoing mail application's design will automate the letter format instead of requiring human entry for each letter that the community or subdistrict people require. The purpose of this application is to make the most of the village's current computer equipment, which is currently only being utilized to replace manual typewriters. Apps that are developed to be web-based but are actually used offline or locally, with the intention of enabling future development—if feasible—to be done online. The created program stores its data in a system database, making it simple to locate previously written letters. The availability of user-friendly programs that are simple to use and don't require specialized knowledge is one of the outcomes of this effort. A further enhancement of this outgoing letter application could be achieved by considering the demands of the village or sub-district.

Penelitian ini difokuskan untuk membantu dalam proses menentukan prioritas pengembangan infrastruktur di desa. Penggunaan metode yang umumnya masih memiliki kekurangan. DSS didesain untuk mendukung semua langkah pengambilan keputusan dan membantu mengevaluasi setiap kriteria yang muncul dengan metode AHP (Analytical Hierarchy Process), menetapkan kriteria dan memberikan bobot nilai sehingga mempermudah dalam mengambil keputusan terkait prioritas pembangunan infrastruktur yang dibutuhkan oleh masyarakat. Hasil penelitian ini menunjukkan bahwa penyediaan air bersih menjadi prioritas utama dengan bobot sebesar 0.69, diikuti oleh pengelolaan sampah dengan bobot prioritas sebesar 0.15. Prioritas ketiga adalah sanitasi dengan bobot prioritas 0.11, dan prioritas terakhir adalah perumahan atau bantuan perbaikan rumah bagi masyarakat yang kurang mampu dengan nilai bobot prioritas sebesar 0.06.This research is focused on assisting in the process of determining the priority of infrastructure development in the village. The use of commonly employed methods still has its limitations. The Decision Support System (DSS) is designed to support all steps of decision-making and aid in evaluating each criterion using the Analytical Hierarchy Process (AHP) method. It establishes criteria, assigns weight values, thus facilitating decision-making related to the priority of infrastructure development needed by the community. The results of this research indicate that the provision of clean water is the top priority with a weight of 0.69, followed by waste management with a priority weight of 0.15. The third priority is sanitation with a priority weight of 0.11, and the last priority is housing or home improvement assistance for the less privileged with a priority weight value of 0.06.

Work as a nurse requires direct contact with patients, for example when carrying drugs or changing IVs. However, since the COVID-19 pandemic, awareness to reduce direct contact with patients is increasingly needed. Moreover, direct contact with patients with infectious diseases, such as covid-19. For this reason, it is necessary to create a tool / robot that can connect nurses and patients, especially patients with infectious diseases. In this study, a robot design and implementation was made that can assist nurses in delivering drugs to patients, without having to make direct contact with patients. IoT-based designed robots using NodeMCU, ESP8266 and Blynk. NodeMCU ESP8266 is used as a data processor and smartphones are used as remote controls via the internet. Data from the smartphone is processed by NodeMCU then sends a signal to the robot actuator via the L298N driver motor to drive the wheels. Furthermore, the internet-connected IP camera is used for live streaming on smartphones through the V380 Pro application as a directional guide. Then to prevent collisions, the ultrasonic sensor HCSR04 will send data to NodeMCU ESP8266 if there is an obstacle at a distance of 30 cm in front of the robot, so that the robot will move backwards. The experimental results show that the robot can run well where the robot is controlled by a nurse using the Blynk IoT application and V380 Pro on a smartphone via internet media. Then the test was carried out with two methods, namely smartphones using the robot's local Wi-Fi connection and smartphones using cellular networks. The results showed that the response time of the application command on the smartphone to the robot or viewing video results from the IP Camera was affected by the condition of the internet network used.
