Abstract

Per capita vegetable consumption in Indonesia has increased from 54,291 kg in 2018 to 58,477 kg in 2021. This increase highlights the need for more efficient vegetable cultivation systems, such as polyculture, where multiple types of plant are grown in one location. However, the suitability of plants for polyculture systems has traditionally been determined using approximate methods. To address this, the research utilizes the ECLAT algorithm with vegetable production data from BPS to identify which crops are frequently grown together in each sub-district. Furthermore, to identify areas with potential for developing vegetable crop pairs, clustering was carried out using the K-Medoids algorithm. The findings reveal that the most commonly paired vegetable plants in sub-district of Greater Jakarta are "Cucumber & Long Beans" and "Spinach & Kale". These sub-districts were grouped based on crop pair production into 3 clusters with high, medium and low production levels. The research concludes that the highest level of vegetable crop pair production is in Bogor Regency.

Abstract

Indonesia memiliki jumlah desa yang sangat besar, yaitu sebanyak 83.794 desa, sehingga transformasi digital memegang peranan penting dalam meningkatkan kesejahteraan masyarakat pedesaan. Desa digital adalah desa yang menerapkan teknologi informasi untuk mendorong efisiensi pelayanan publik, penguatan ekonomi masyarakat desa, serta peningkatan kualitas hidup masyarakat desa. Namun, rendahnya literasi digital dan terbatasnya kapasitas sumber daya manusia masih menjadi kendala dalam implementasi desa digital. Penelitian sebelumnya yang bekerja sama dengan FAO pada program Digital Village Initiative (2023) telah menghimpun data melalui pendekatan etnografi terhadap 160 desa digital dan 100 inovasi digital yang dikategorikan dalam 10 kelompok, seperti Agri-Food Marketing and E-commerce, E-Government, Smart Farming, dan Social Service. Sayangnya, informasi desa digital saat ini tersebar secara tidak terstruktur sehingga sulit diakses dan dimanfaatkan oleh desa lain. Penelitian ini bertujuan mengembangkan platform Knowledge Management System (KMS) desa digital menggunakan pendekatan Prototyping melalui tahapan komunikasi, perencanaan cepat, desain, pembuatan prototipe, dan evaluasi. KMS ini ditujukan bagi inovator, perangkat desa, dan masyarakat desa, serta dapat diakses secara publik. Modul yang dikembangkan memuat informasi inovasi digital dalam 10 kategori beserta deskripsinya, profil inovator, profil desa digital, serta fitur asesmen kesiapan digital desa. Hasil ini diharapkan dapat mempercepat diseminasi pengetahuan dan adopsi inovasi digital antar desa di Indonesia.

Abstract

Digital transformation at the village level is a strategic element in promoting equitable development and improving public service delivery. However, the level of digital readiness across regions remains uneven. This study aims to classify the digital readiness of villages in West Java Province by utilizing data from Open Data Jabar (opendata.jabarprov.go.id) related to the number of digital villages, internet access, and village development strata. A Decision Tree classification algorithm was employed to categorize regions into two readiness classes: high and low. The modeling results indicate that the number of self-reliant (mandiri) villages and the percentage of villages with internet access are the most influential variables in the classification. Although internet infrastructure is available in most areas, it does not always correspond to the level of village digitalization. Districts with high internet access but a low number of self-reliant villages are still classified as having low readiness. The model achieved an accuracy of 83%, although its performance in identifying the high readiness class was limited due to class imbalance in the dataset. Spatial visualization was also used to highlight regional disparities in digital readiness. This study provides an early contribution to digital readiness mapping of villages using a machine learning approach in Indonesia.

Abstract

Public health in West Java faces complex challenges, including disparities in healthcare access, malnutrition, and socio-economic inequalities across districts. These conditions require data-driven analysis to identify patterns of disparity and provide evidence-based guidance for policy intervention. This study aims to cluster districts/cities in West Java based on health and social indicators using Principal Component Analysis (PCA) for dimensionality reduction, followed by K-Means and K-Medoids algorithms for clustering. Data from 27 districts/cities during 2019–2024 were analyzed after standardization. PCA extracted two principal components explaining 61.4% of the total variance. Scree plot and silhouette results indicated three optimal clusters. Comparative analysis revealed that the average silhouette score of K-Means was 0.31, while K-Medoids achieved a higher score of 0.34, suggesting more stable and robust partitioning against outliers. In 2024, Cluster 1 consisted of regions with adequate healthcare facilities and lower prevalence of underweight children; Cluster 2 grouped regions with limited health infrastructure and higher malnutrition problems, while Cluster 3 showed intermediate conditions. Therefore, K-Medoids outperformed K-Means by producing more consistent clustering across years. These findings offer practical recommendations: Cluster 2 should be prioritized for interventions such as improving primary healthcare access and nutrition programs, Cluster 1 requires maintenance of service quality, and Cluster 3 should be targeted for gradual reinforcement.

Abstract

This study compares the performance of three hedging strategies, Collar, Bear Put Spread, and Long Strangle, in a case study of PT GoTo Gojek Tokopedia Tbk (GOTO) stock. The analysis focuses on the risk management effectiveness and profit potential of these strategies within an emerging market context. The research utilizes weekly stock price data from July 2023 to June 2024 (54 observations). The methodological procedures include calculating returns and volatility, testing return normality using the Shapiro-Wilk test, determining European option prices using the Black-Scholes model with a 6% risk-free interest rate, and conducting profit simulations. The findings indicate that the Collar strategy provides maximum protection against stock price declines, albeit with limited profit potential. The Bear Put Spread strategy proves effective in generating returns during moderate price decreases while offering lower risk and cost. Conversely, the Long Strangle strategy possesses high profit potential during significant price volatility but carries the risk of total loss if stock prices remain stagnant. As a comprehensive comparison of these three option strategies applied to GOTO stock, this study recommends the Collar strategy as the optimal choice for risk-averse investors during bearish trends.
