Artikel ini bertujuan untuk memprediksi tingkat inflasi di Kota Samarinda, Kalimantan Timur dengan mengimplementasikan algoritma cerdas, Backpropagation Neural Network (BPNN). Data tingkat inflasi diperoleh dari Biro Pusat Statistik Provinsi (BPS) Kota Samarinda https://samarindakota.bps.go.id/ periode Januari 2012 hingga Januari 2017. Pengukuran akurasi prediksi algoritma BPNN menggunakan metode mean square error (MSE). Berdasarkan hasil percobaan, metode BPNN dengan parameter arsitektur 5-5-5-1; fungsi pembelajaran adalah trainlm; fungsi aktivasi adalah logsig dan purelin; laju pembelajaran adalah 0.1 mampu menghasilkan tingkat kesalahan prediksi yang baik dengan nilai MSE sebesar 0.00000424. Hasil penelitian menunjukkan bahwa algoritma BPNN ini dapat digunakan sebagai alternatif metode dalam memprediksi tingkat inflasi dalam rangka mendukung pertumbuhan ekonomi yang berkesinambungan sehingga dapat meningkatkan kesejahteraan masyarakat di Kota Samarinda, Kalimantan Timur.
The design of the detection system in this study using ESP32 module that includes Wi-Fi: 802.11 b / g / n and Bluetooth: v4.2 BR / EDR and Bluetooth Low Energy (BLE). In general, the automatic door lock system using a fingerprint or RFID card in its implementation, but this study using BLE which is a component of iBeacon which has a function as a result of the fingerprint and RFID card. ESP32 have a duty to control the door lock in order to open and lock the door using relays and solenoid system, in addition to the BLE on ESP32 serves to detect the presence of individuals where Bluetooth Device Address (BD_ADDR) smartwatch or individual gadget is already registered on ESP32. Based on the experimental results, the system can detect a user's presence smartwatch on the Received Signal Strength Indicator (RSSI), which is determined on the program was uploaded to ESP32. This system can also be developed in the future and applied to a variety of special purposes such as absenteeism, indoor mapping, and smart home.
The popularity of public transportation has increased as infrastructures have been repaired and other supporting facilities have been added. One of the facilities which can be added in the transportation system is the implementation of Near Field Communication in order to accelerate each transaction in the transportation system. In airports, transaction activities need to be done efficiently, like claiming baggage at the baggage carousel. The speed of transaction to claim the baggage depends on the number of officers, passengers, and the amount of baggage brought by the passengers. In the conventional system, the most effective way of getting the maximum speed of transaction is to have officers as many as the number of passengers, but this is not efficient regarding the use of human resources. The use of Near Field Communication can solve the problem related to the efficiency of resources, safety, and the increasing speed of transaction.
Hidroponik merupakan metode penanaman yang tidak menggunakan tanah sebagai media tanamnya. Budidaya tanaman menggunakan sistem hidroponik memiliki beberapa keuntungan yaitu tanaman lebih berkualitas, tidak mudah terserang hama penyakit, dapat ditanam terus-menerus tanpa mengenal musim. Di kota Samarinda, ada beberapa pembudidaya tanaman hidroponik, salah satunya Boekha Farm. Jenis sayuran yang dibudidayakan berupa selada, sawi daging, kangkung, bayam, dan daun mint. Kendala yang dihadapi oleh Boekha Farm yaitu jumlah sayuran yang dipanen lebih besar dari jumlah pesanan yang datang. Hal ini mengakibatkan sayuran menjadi tersisa dan membutuhkan pelanggan baru agar semua sayuran yang dipanen habis terjual. Oleh karena itu perlu upaya memperkenalkan Boekha Farm serta mempromosikan produknya kepada kalangan masyarakat yang lebih luas. Video company profile dapat dikembangkan menjadi media untuk mempromosikan kebun budidaya Boekha Farm agar dapat lebih dikenal oleh masyarakat. Metode yang digunakan untuk melakukan pengembangan media promosi ini yaitu metode Villamil Molina. Media ini dapat memperkenalkan Boekha Farm sebagai pembudidaya sayuran hidroponik. Video company profile menyajikan informasi terkait Boekha Farm beserta produknya dan informasi mengenai hidroponik.
