Judul: Pertumbuhan Pertanian Bernilai Tinggi dan Transformasi Perdesaan di Wilayah Indonesia
Abstrak: Agriculture and rural areas are two things that cannot be separated. Rural transformation can be seen by the shifting focus of production from low-value agricultural commodities to high-value agricultural commodities. This study aims to analyze the condition of high-value agricultural GDPR and determine the effect of IPIs on high-value agricultural GDPR and its implications for rural transformation in Indonesia in the period 2000 to 2018 using multi-annual data and 25 provinces as individual objects. The analysis methods used are descriptive analysis and panel data regression analysis. The research results show that there is high-value economic growth in Indonesia. The variables bank, electricity, middle school & high school (secondary) education facilities, General Allocation Funds (DAU), PMA in the agricultural sector and PMDN in the agricultural sector have a significant positive effect. Meanwhile, the Village Fund variable has a significant negative effect. However, the cooperative, market and PMDN variables in the non- agricultural sector have an insignificant positive effect. Meanwhile, non- agricultural PMA has an insignificant negative effect on high-value agricultural GDPR.

Judul: Rural Transformation and Income in Indonesia
Abstrak: Transformasi perdesaan merupakan suatu proses perubahan sosial yang komprehensif dimana masyarakat perdesaan melakukan diversifikasi ekonomi dan mengurangi ketergantungan terhadap sektor pertanian. Proses transformasi perdesaan yang sedang terjadi di Indonesia ditandai dengan meningkatnya share PDRB high-value agriculture dan share tenaga kerja nonpertanian. Tujuan penelitian ini adalah mengetahui gambaran tipologi dan pengaruh transformasi perdesaan terhadap pendapatan perdesaan. Penelitian menggunakan data sekunder multitahunan dari 2000 hingga 2018 dengan observasi individu 25 provinsi dan diestimasi menggunakan metode data panel statis. Hasil penelitian menunjukkan bahwa pertumbuhan transformasi perdesaan tidak terjadi pada kecepatan yang sama antarprovinsi. Transformasi perdesaan diketahui berpengaruh secara positif dan signifikan terhadap pendapatan perdesaan di Indonesia., Rural transformation is a process of comprehensive social change where rural people diversify their economy and reduce their dependency on agricultural sector. Rural transformation process is happening in Indonesia shown by increasing of share of high-value agricultural GDPR and share of non-farm employment. This research aims to illustrate the typology and impact of rural transformation to rural income. This research uses multiyear secondary data from 2000 to 2018 with individual observation of 25 provinces and estimated by using static panel data method. This research showed that rural transformation growth not happened at the same speed across provinces. Rural transformation also has a positive and significant impact to rural income in Indonesia.

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.
