2017: This HMI is used to insert downtime reasons for specified machine in industry. This HMI uses STM32F7 as an LCD device. STM32F7 series is a microcontroller with very high-performance MCUs with Arm Cortex-M7 core. The used language is C/C++

2017: Electronic circuit is an inseparable part of electronic devices, so it's very important to make a good circuit design. For this project the Eagle software is used to make beautiful design of electronic circuit layout. The layout is a double layer type so electronic components can be placed on up or bottom layer of PCB (Printed Circuit Board).

2017: IoT (Internet of Things) is a system which can connect smart objects to the internet, and exchange data. Smart objects means objects that have the ability not just connect to the internet but can tranfer the specified data and save to the cloud storage and can be integrated to a specified system. With IoT technology, the smart objects can be controlled or monitored from everywhere and anytime. For this project, Arduino and Wemos is used as a gateway which served to connect water level sensors to the cloud. So the level of the water in a tank can be monitored from everywhere and anytime.

2017: AutoCAD Course is a course which aims to gain skill on design using AutoCAD Software. Android Studio is an application to create app for android phone.

2018: Develop Image Recognition for Safety Office using FaceNet and OpenCV in Python. For facial recognition method, the MTCNN algorithm is used. MTCNN (Multi-task Cascaded Convolutional Neural Networks) is an algorithm consisting of 3 stages, which detects the bounding boxes of faces in an image along with their 5 Point Face Landmarks.

2018: CNN (Convolutional Neural Network) is a Deep Learning algorithm that can learn from a bunch of image datasets with specified label/name, so it can distinguish or classified one image from another based on label/name of image datasets. Keras is a high-level neural networks API, written in Python and capable of running on top of TensorFlow, CNTK, or Theano.

2018: Forwarder system is used to collect data from PLC and also forward the data to server. Forwarder system is divided into two sub systems, Data Collector and Forwarder. Forwarder served to forward raw data from PLC to HMI (Human Machine Interface) and also parsed that data to be sent to Data Collector. As its name, Data Collector served to collect the parsed data from all Forwarders and then sent to server.

2018: Create desktop application for scanning finger on finger scanner that is integrated in warehouse smart store. The application is created in C# language.

2019: Visitor Tracker is an application that can track the number of visitors of a place in a day and how many visitors are still in the place. The visitor data is saved in MySQL database. This application has already integrated with Whatsapp messenger, so every arrival and departure of visitor, the application will send notifications to your Whatsapp messenger. Notification about visitor can send not only to single number but can send to multiple number or even groups. This can boost the security of that area.

2019: This is a data science project that finding the relation between recession and mean housing prices in US especially in University Town. Based on that graph, the P-Value for the relation between recession and mean housing prices is 0.002700017376846495. So the conclusion is the recession is not affecting the mean housing prices in University Town in US.

2019: POS (Point of Sale) is a place where the customer makes a payment for products or services at a store. Simply put, every time a customer makes a purchase at a store, so the Point of Sale transaction is occur. For this project, Felgo is used. Felgo is a cross-platform development tool, based on Qt framework. It is easy to make cross-platform application using Felgo.

2019: HMI (Human Machine Interface) is used as an interface that connects human to machine, system or devices. For this project, HMI is made using PyQt5. PyQt5 is a Python binding of the cross-platform GUI toolkit Qt, implemented as a Python plug-in. PyQt is developed by British firm Riverbank Computing and it's free. This is the first project of making HMI. This HMI is used for Lakban Machine.
