Prediction of Diabetes Using Artificial Neural Network

Prediction of the likelihood of having Diabetes using Artificial Neural Network (ANN) Algorithm. This prediction uses a reference of over 50,000 classified data records with diabetes as a parameter including age, gender, body mass index (BMI), hypertension, heart disease, smoking history, HbA1c level, and blood glucose level. This dataset can be used to build a machine learning model to predict diabetes in patients based on their medical history and demographic information. In this process, diabetes prediction is performed on 1,000 data, which in this case refers to patients.

K-Means Clustering To Grouping Country Priorities That Need Assistance

Clustering uses the K-Means Algorithm and determines the number of clusters using the Silhouette Method. The method used for grouping countries uses several socio-economic and health factors, namely:

1. child_mort (Death of children under 5 years of age per 1000 live births)
2. exports (Exports of goods and services per capita. Given as %age of the GDP per capita)
3. health (Total health spending per capita. Given as %age of GDP per capita)
4. imports (Imports of goods and services per capita. Given as %age of the GDP per capita)
5. income (Net income per person)
6. inflation (The measurement of the annual growth rate of the Total GDP)
7. live_expect (The average number of years a new born child would live if the current mortality patterns are to remain the same)
8. total_fer (The number of children that would be born to each woman if the current age-fertility rates remain the same)
9. gdpp (The GDP per capita. Calculated as the Total GDP divided by the total population).

Based on the results of the clustering of countries in the group with a very low level of need (C1), including Brunei, Qatar and United Arab Emirates, countries in the group with a low level of need (C2) include Russia, China and Indonesia, countries in the group that include moderate levels of need (C3) include Singapore, Malta, and Luxembourg, countries in the group that include high levels of need (C4) include Mongolia, Nigeria, and Venezuela, and countries in the group those with a very high level of need (C5) include Guinea, Central African Republic, and Kenya.

Amarta, Robot with 4 Mecanum Wheels and Rack & Pinion System Controlled by PS3 Joystick

The robot is a newer version of the previous robot, with the addition of a rack & pinion system so it can pick up coins from below, and is controlled using a PS3 joystick. This robot is used in the Indonesian Robot Contest (Kontes Robot Indonesia - KRI) 2023 in the Indonesian Thematic Robot Contest (Kontes Robot Tematik Indonesia - KRTMI) category. In this contest, there are changes to the rules from the previous year. One of them is an octagonal coin, with the placement of the coin having to cover the circle on the field. At the national level, matches against robot opponents are a battle of strategy and speed with different fields in the form of a green screen and combined on a monitor. Robot and coin detection uses a QR code that is installed and read as a robot or coin on the jury's computer. So to find out where to place the coins by looking at the monitor, there is also a penalty if the robot hit an opposing robot or exceed the maximum speed limit.

Product Giveaway Performance Dashboard

Geographic Information System for Number of Residents of Each Village in Java Island by Age Range

The Geographic Information System (GIS) for Village Population in Java Island utilizes a color gradient from red to blue to visually represent the number of residents, with red indicating lower and blue indicating higher population densities. This system incorporates an interactive pop-up feature for each village, offering specific details such as the number of residents, village name, subdistrict, and district. The intuitive color scheme allows for a quick assessment of population concentrations, while the pop-up feature facilitates a detailed exploration of demographic patterns. This GIS serves as a valuable tool for data-driven decision-making and strategic planning based on nuanced insights into population distribution across Java Island.

Floating e-TPAS Based on IoT

Floating e-TPAS (Tempat Pemrosesan Akhir Sampah) are waste containers that are designed to float in water, so they can maintain the presence of waste stored in them so that they do not scatter and get carried away by high tides. This device was used at I2ASPO 2023 in the University category of IoT and Its Applications. This research takes place in Kampunglaut, Cilacap, Indonesia, because the majority of the area is water and there are many mangrove forests. This causes the behavior of Kampunglaut residents to prefer to dispose of waste directly into the water because of the difficulty in transporting waste from their homes to the final waste collection site. Moreover, Kampunglaut has no waste collection sites at all and is unsuitable due to frequent tides. This Floating e-TPAS uses an ultrasonic sensor as a detector that is or is not full, and also NodeMCU as an IoT device, connected to a Smartphone that has a Blynk application as a data receiver and also regulates the percentage of full. If it is full, the Smartphone will receive a notification that the Floating e-TPAS is full.
