Judul: MSE Clusterization Based On Digitalization Level In West Java
Abstrak: Infrastruktur dan penetrasi digital di Indonesia terus mengalami perkembangan bahkan sudah menyasar ke bagian operasional bisnis yang mendorong terciptanya ekosistem bisnis yang terintegrasi dan memudahkan akses kontrol. Penelitian ini bertujuan menganalisis penerapan digitalisasi pelaku UMK. Penelitian menggunakan 100 UMK yang ditentukan dengan teknik purposive sampling dan menggunakan analisis deskriptif. Hasil penelitian menunjukkan skor digitalisasi berkisar antara 0-17 dengan rata-rata 4,73. Mayoritas pelaku UMK berada pada level 1 (beginner) dan tergolong rendah. Untuk meningkatkan penerapan digitalisasi pelaku UMK, perlu pembinaan dari pemerintah, komunitas, praktisi bisnis dan pakar digital melalui program sosialisasi dan workshop. Selain itu, pelaku UMK mengalami gangguan sinyal sehingga pemerintah perlu meningkatkan kualitas infrastruktur internet, Digital infrastructure and penetration in Indonesia continue to develop and have even targeted business operations that encourage the creation of an integrated business ecosystem and facilitate access to control. This study aims to analyze the application of digitalization of MSE actors. The study used 100 MSEs determined by purposive sampling techniques and used descriptive analysis. The results showed a digitization score ranging from 0-17 with an average of 4.73. The majority of MSE actors are at level 1 (beginner) and are classified as low. To increase the application of digitalization to MSE actors, guidance from the government, communities, business practitioners and digital experts is needed through socialization programs and workshops. In addition, MSE players experience signal interference so the government needs to improve the quality of internet infrastructure

Judul: Analysis of MSME behavior in the digital transformation process using a dynamic system model
Abstrak: Usaha mikro, kecil, dan menengah (UMKM) merupakan salah satu pilar penyangga perekonomian Indonesia, di mana UMKM menyumbang sekitar 60,34% dari total PDB Indonesia di tahun 2022. Saat ini, perkembangan digital yang pesat menuntut UMKM untuk melakukan transformasi digital pada sistem bisnis. Namun, dalam proses melakukan transformasi digital, banyak hambatan dan tantangan yang memengaruhi hal tersebut. Hambatan dan tantangan yang paling sering UMKM alami antara lain keterbatasan literasi digital, keterbatasan teknologi, dan keterbatasan keuangan. Penelitian ini bertujuan untuk menganalisis pengaruh faktor UMKM terhadap performa transformasi digital UMKM dan merumuskan rekomendasi kebijakan melalui pemodelan sistem dinamik terkait transformasi digital UMKM. Pemodelan dilakukan secara bertahap dengan pembuatan diagram kausatik dan diagram stock and flow (SFD). Formulasi pada SFD menggunakan nilai signifikansi dengan metode structural equation modeling. Simulasi dilakukan bertingkat dari level transformasi paling rendah hingga level transformasi paling tinggi. Berdasarkan hasil simulasi, dihasilkan kebijakan pemerintah untuk memfasilitasi pelaku UMKM dalam hal literasi, pemodalan, dan akses teknologi untuk meningkatkan kemampuan transformasi digital UMKM., Micro, small, and medium enterprises (MSMEs) are one of the pillars supporting Indonesia's economy, contributing approximately 60.34% of the total GDP in 2022. Currently, the rapid digital development requires MSMEs to undergo digital transformation in their business systems. However, there are many obstacles and challenges affecting this process. The most common challenges faced by MSMEs include limited digital literacy, limited technology, and financial constraints. This study aims to analyze the impact of MSME factors on the performance of digital transformation and to formulate policy recommendations through dynamic system modeling related to MSME digital transformation. The modeling is conducted in stages by creating causal loop diagrams and stock and flow diagrams (SFD). The formulation in the SFD uses significance values with the structural equation modeling method. Simulations are carried out in stages, from the lowest transformation level to the highest transformation level. Based on the simulation results, government policies are recommended to facilitate MSMEs in terms of literacy, funding, and technology access to enhance their digital transformation capabilities.

Judul: Hydroxyapatite-Chitosan Composite Coating on Stainless Steel 316 to Improve Corrosion Resistance
Abstrak: Metals that were used in bone implantation should have good corrosion resistance that were not easily corroded when implanted into the body. Metal corrosion resistance of stainless steel 316 can be enhanced through the metal coating by hydroxyapatite-chitosan composite with composition ratio of hydroxyapatite (gram) and chitosan 3% (mL) 0.2:0, 0.2:0.1, 0.2:0.5, 0.2:1.0, and 0.2:1.5. Besides improving the corrosion resistance of metal, the presence of chitosan also maintain the position of hydroxyapatite on metal surfaces. Corrosion resistance increases with increasing amount of chitosan added and the best composition of hydroxyapatite-chitosan composite was 0.2:1.0.
