Apotek Sinom Sehat beralamat di Jalan Bahari, Sinom Karanganom Weleri. Apotek Sinom Sehat tidak hanya menjual berbagai obat tetapi juga menjual alat-alat kesehatan, barang bebas, dan kosmetik. Seluruh kegiatan penerimaan kas maupun pengeluaran kas Apotek masih dicatat didalam buku kas. Dalam transaksi penjualan dan pembelian dicatat oleh kasir kemudian  direkap  kembali  oleh  bagian administrasi ke dalam buku kas . Hal ini tentunya tidak efisien dalam segi waktu serta biaya yang dikeluarkan untuk membeli buku dan alat tulis lainnya. Kemudian dalam setiap perhitungan transaksi, terkadang terdapat transaksi yang tidak terhitung menyebabkan data yang dihasilkan tidak akurat karena adanya perbedaan antara jumlah penerimaan atau pengeluaran kas dengan catatan pada buku kas. Pembuatan laporan keuangan masih menggunakan program Microsoft Excel yang tidak otomatis sehingga mengharuskan bagian administrasi membuat rumus-rumus excel dahulu. Berdasarkan penelitian tersebut maka penulis membuat perancangan sistem informasi akuntansi arus kas perusahaan dagang dengan metode langsung di Apotek Sinom Sehat agar didalam proses pencatatan dan perhitungan arus kas di Apotek Sinom Sehat menjadi lebih efektif dan efisien. Aplikasi ini menggunakan software sublime text 3 sebagai text editor dan database MySQL

BPNT is non-cash food aid. What is paid in the form of food by the government. The BPNT program aims to provide opportunities for the government to improve food security and provide balanced nutritional value to poor families, such as in Muncan Village, the BPNT assistance program is distributed every month. In decision-making, the selection of BPNT recipients is constrained because quite a lot of data that is processed or selected by the apparatus is still done manually. So far, the existing system has not been optimal for selecting BPNT recipients with the existing criteria. Data management still uses a manual system and is not effective in determining who is entitled to receive BPNT and who is not. The method used in the decision support system for Social Assistance for Non-cash Food Assistance (BPNT) is the ARAS method to make it easier to identify who is eligible to receive and who is not. support Based on the weight value obtained in the assessment process. The criteria for determining BPNT assistance include: occupation, number of dependents, income, home ownership, electric power and age. For testing using the Black Box method using the Boundary Value technique focusing on errors. The programming language used is PHP or Hypertext Preprocessor.

The proposed office door security system combines RFID (Radio-Frequency Identification) Sensor and PIR (Passive Infrared) Sensor technology with Telegram-based communication. The design of this system requires RFID and PIR sensors to be formed in order to produce a system design that is made to meet the needs of system users. The aim of this system is to increase the security level of access to office space by combining identification of access owners via RFID cards and motion detection using PIR sensors. Communication through the Telegram platform is used to provide real-time notifications to access owners when there is activity at the office door. The control system for this device is controlled by the Esp32 Microcontroller, using 4 inputs, namely Rfid, PIR, Keypad and telegram sensors, as well as 5 outputs, namely Selenid Doorlock, Buzzer, LCD, Relay and telegram. By using the esp32 microcontroller to process data and the telegram application for IoT as a link between devices and smartphones. With 2 sensors as logic inputs for the esp32 microcontroller, the number of outputs that occur is 5, namely in the form of a sound from a buzzer as a warning, and a PIR as a sensor to open the door from the inside. When opening the RFID with a card tag, then the selenoid doorlock will open. Overall, the design of this office door security system has the potential to improve security and monitoring in the office space. By combining the technology of RFID sensors, PIR sensors and Telegram-based communication, this system enables accurate identification, real-time motion detection and fast interaction between the security system and the access owner. So that Telegram is successful in sending notifications if someone enters, that is, they will appear. "User Name Open Door: according to the registered UID", but if it fails "Unregistered User Failed Login Attempt" The LCD will also issue an output if someone has registered their RFID tag or not
