Abstract PT. DhanaJaya BogaIndo has more than twenty restaurants spread across Jakarta, Surabaya and Australia. At present complaints regarding services and food served are still being done by providing limited criticism and suggestions during operational hours, so employees in the service section always record complaints and suggestions from customers who come to restaurants are accommodated, then convey related to food, service and the environment dirty one. related to customer complaints. Information on customer complaints can be received directly by management, so actions can be taken quickly.

Kehilangan merupakan merupakan hal yang biasa dapat terjadi oleh setiap individu, baik kehilangan barang maupun seseorang. dan sementara itu pencarian orang hilang pada masa sekarang ini melalui media sosial ataupun dengan mengirimkan selebaran, dengan begitu sulit sekali untuk menyebarkan informasi-informasi detail mengenai informasi orang hilang tersebut, Untuk itu diperlukan suatu wadah yang dapat dipakai untuk dapat menyediakan informasi dan mengirim informasi tentang kehilangan orang,dan untuk itu digunakan metode social network analysis untuk menganalisis tentang kehilangan orang dengan menggunakan metode tersebut penulis dapat menganalisis tentang kefektifan dari pencarian orang hilang yang ada sebelumnya dan penulis mengambil dataset dari twitter tentang orang hilang dan didapatkan hasil dari 241 node yang diambil pada periode waktu 20-05-2022 sampai dengan 27-05-2022 pada media sosial twitter, hasil dari penerapan metode social network analysis , dan hasil dari penelitan menggunakan metode social network analysis tersebut bahwasannya aktor (node) yang memiliki nilai followers rank tertinggi belum tentu menjadi suatu aktor (node) yang berpengaruh dalam jaringan sosial. Dan dapat disimpulkan jika menggunakan media sosial untuk memposting orang hilang di dalam media sosial twitter, nilai followers rank (Jumlah pengikut) tidak terlalu berpengaruh terhadap postingan informasi mengenai orang hilang tersebut, dan dapat disimpulkan juga nilai followers rank bukan hal yang terlalu berpengaruh terhadap banyaknya interaksi dlam suatu postingan dalam hal ini mengenai orang hilang dalam sosial media twitter. Jadi penggunaan media sosial twitter untuk mencari orang hilang tetap dapat digunakan akan tetapi kurang efektif yang sehingga untuk penyebaran informasi orang hilang ini memerlukan suatu wadah yang menyediakan informasi khusus kehilangan orang.

Network Operation Central (NOC), an Enterprise Service Division which functions to carry out monitoring and supervision activities of Telkom network equipment located at Plaza Indonesia. Customer satisfaction is the basis and goal that is always hoped for by customers, by carrying out maintenance activities of network devices, and carrying out solutions when problems occur in customers are expected to be an efficient and effective service quality standard. This study wants to know that the construction of a monitoring system for NOC work activities can improve service quality. The quality of this system can be measured using the ISO9126 model, by adapting four characteristics of software quality: functionality, reliability, usability, and efficiency. The system development model uses the Rapid Application Development (RAD) and Joint Application Development (JAD) models. Researchers will analyze and design the system using the Unified Model Language (UML), then by coding with PHP programming and MySQL databases, and data collection using a questionnaire, and system testing using the Blackbox Testing model. Based on testing using ISO 9126 the results are functionality (80%), reliability (79%), usability 86%), and efficiency (79%). Overall the result was 81% (good).

Currently, most of the patients seeking treatment at the hospital use the National Health Insurance (JKN) organized by the Healthcare and Social Security Agency (BPJS Kesehatan). In some hospitals, the figure is above 80%. Considering the very high number of BPJS Kesehatan participant seeking treatment at the hospital, a good data management method is needed, especially regarding the management of drug. Drug supply needs to be analyzed from time to time so that it can help predict future needs. An adequate supply of drugs and as needed is one of the things that affect service to patients. The availability of sufficient stock is expected to accelerate service to patients so that they do not have to wait long. Patients who are served quickly are expected to be satisfied. The impact of this patient satisfaction will increase the number of patient visits to the hospital. To support this, it is necessary to create a system that can estimate drug needs. The system can predict drug demand by using drug sales data to JKN participant patients for five years. Drug data used as research samples and then processed using an algorithm is the Naive Bayes Classifier. The Naive Bayes Classifier method is a method used to predict future opportunities using the basis of previous experience. A distinctive feature of this method is that it uses a very strong assumption of the independence of each event. While software testing uses the User Acceptance Test (UAT) model. Based on testing using this method, the system can be well received by users with a score of 78.64% (good).
