Abstract

Abstract This study analyzes the disparity in primary education quality across Indonesian regions using K-Means clustering methodology to group 38 provinces based on classroom adequacy indicators and teaching staff availability for the 2023-2024 period. Adopting the CRISP-DM methodology and utilizing datasets from the Ministry of Education, Culture, Research, and Technology, this research reveals significant educational gaps across Indonesian regions. The analysis results show three clusters reflecting educational conditions: Cluster 1 (low category) encompasses 23 provinces (67.6%) dominated by Eastern Indonesia regions such as Papua, Maluku, and other remote areas; Cluster 2 (medium category) consists of 13 provinces (38.2%) including South Sumatra, Riau, and DKI Jakarta; and Cluster 3 (high category) contains only 3 provinces: East Java, West Java, and Central Java. Clustering validity is confirmed through silhouette coefficient with the highest value of 0.795 for Cluster 2. These findings identify structural inequality between Java and outer Java regions, providing empirical foundation for the government to design more targeted educational equity policies, with priority on infrastructure rehabilitation and teaching staff augmentation in disadvantaged areas to achieve national educational justice. The research demonstrates that educational quality distribution in Indonesia remains heavily concentrated in Java, while remote and eastern regions face significant challenges in both physical infrastructure and human resources, requiring comprehensive government intervention strategies for sustainable educational development. Keywords: K-Means clustering, primary education, regional disparity, educational infrastructure, teaching personnel.

Abstract

The goods sorting system is one of the important processes in the logistics system, especially when applied to work in the palm oil processing industry. The problem that occurs in the ripeness of palm fruit is that palm oil farmers find it difficult to distinguish the level of ripeness of palm fruit which will later affect the selling price of palm oil. Therefore, an automatic sorting conveyor control system is designed using an Arduino microcontroller to detect the level of ripeness of palm fruit by applying the neural network algorithm method in identifying the type of palm fruit based on the level of ripeness of the palm fruit. Then the integration of several sensors connected to the Arduino will later make it easier for the servo motor to determine the ripeness of the palm fruit. The results obtained using the neural network algorithm in processing the level of accuracy in identifying raw or ripe palm fruit can operate with the program settings that have been designed. In the Matlab simulation with the neural network method, an image pattern is obtained where if the result is close to 1 then the palm fruit is ripe, otherwise if there is nothing close to the value 1 then the palm fruit is still raw. The recorded data can later be a reference for palm oil farmers in making sales more accurately.

Abstract

The utilization of solar energy in Medan city has not been optimal, which is a case that requires a solution. This is due to the lack of understanding of the working concept and the factors influencing the efficiency of power generated by solar panels. The research conducted in the Medan City area, North Sumatra, aims to determine the performance of the monocrystalline off-grid solar panel conversion in response to weather fluctuations. Based on the study of solar panel performance, the analysis shows that the power generated is influenced by key variables such as voltage, current, power, and light intensity (lux). The voltage of the solar panel remains stable throughout the day, ranging from 11.00 V to 19.80 V, with the peak occurring at 1:00 PM. The current varies, from 0.25 A in the morning to 5.90 A during the day. The peak power is recorded at 1:00 PM, reaching 116.82 Watts, along with the highest voltage and current. The intensity of sunlight (lux) also affects power, with the peak lux of 50,000 occurring at 1:00 PM. Overall, the solar panel performs best between 12:00 PM and 2:00 PM, while the output power decreases in the morning and evening.
