Judul: Regional leakage in community cinnamon commodity agribusiness system and its impact on regional economy: case in Kerinci Regency of Jambi Province
Abstrak: Cinnamon is one of national export commodities which has placed Indonesia as the world’s biggest exporter. Its existence is a source of income in society, source of foreign exchange and the country of employment. Development problem is the low price at the level of farmer’s, affecting the farmers cut off all the trees without effort to manage the plants, and it makes the productivity decrease. In general, the purpose of this research is to analyze the regional leakage in community cinnamon commodity agribusiness system and its impact on regional economy, cases in Kerinci Regency of Jambi Province. The specific purposes are; (1) to analyze cinnamon commodity agribusiness system development (2) to analyze the integration of cinnamon price in farmers and exporter, the competitiveness of cinnamon in international market; and the cinnamon demand in international market; (3) to analyze the contribution the cinnamon to the economy of Kerinci Regency; (4) to analyze regional leakage potential and implication the cinnamon sector to regional economy. The research uses the following model: descriptive, input-output (I-O), econometrics and constant market share (CMS). The research showed that: (1) The cinnamon commodity agribusiness system had inefficiency development system; (2) The cinnamon exporter price was integrated 40% to farmers’ price. The Indonesian cinnamon competitiveness is lower than China’s. The Indonesian cinnamon demand is significantly influenced by the price, economic growth (GDP), and real exchange rate; (3) The cinnamon had an important role in regional economy of Kerinci Regency; (4) The cinnamon had regional leakage potential and its implication to regional economics. To develop cinnamon sector there are several strategies: Develop the agro industry processing, the tree structure industry, the competitiveness, marketing, the farmer’s institution, and government policy.

Judul: Analysis of Indonesian Cinnamon Export Competitiveness in the United State Market
Abstrak: Indonesia termasuk produsen kayu manis di pasar dunia yang bersaing dengan Sri Lanka dan Vietnam. Negara tujuan ekspor kayu manis berada pada Amerika Serikat dengan laju pertumbuhan 16,9%. Harga kayu manis Indonesia selalu mengalami peningkatan, tetapi tidak sejalan dengan volume ekspor. Penelitian ini bertujuan menganalisis daya saing, potensi, serta faktor-faktor yang memengaruhi ekspor kayu manis di pasar Amerika Serikat. Fokus penelitian komoditas kayu manis dengan kode HS 090611 (Spices; cinnamon (Cinnamomum zeylanicum Blume), neither crushed nor ground) pada periode 2016-2021, penelitian ini menggunakan metode Revealed Comparative Advantage (RCA), Export Product Dynamic (EPD), Diamond Porter’s, X-Model Potential Export Product, dan Ordinary Least Square (OLS). Hasil penelitian menunjukan Indonesia mempunyai keunggulan komparatif dan kompetitif, namun perlu mengevaluasi hasil analisis Diamond Porter’s yang menunjukan minimnya kualitas tenaga kerja, minimnya negara tujuan ekspor, kemunduran luas lahan produksi kayu manis Indonesia, minimnya teknologi terbaru, dan minimnya kegiatan industri hilir kayu manis Indonesia. Indonesia juga berada pada pasar optimis serta memiliki hubungan signifikan dengan harga kayu manis, jumlah populasi, dan nilai kurs rupiah di negara tujuan ekspor utama., Indonesia is a cinnamon producer in the world market which competes with Sri Lanka and Vietnam. Cinnamon export destination countries are in the United States with a growth rate of 16.9%. Indonesian cinnamon prices always increase, but not in line with export volume. This study aims to analyze the competitiveness, potential, and factors that influence cinnamon exports to the United States market. The focus of research on cinnamon commodities with HS code 090611 (Spices; cinnamon (Cinnamomum zeylanicum Blume), neither crushed nor ground) in the 2016-2021 period, this study uses the Revealed Comparative Advantage (RCA) method, Export Product Dynamics (EPD), Diamond Porter's , X-Model Potential Export Product, and Ordinary Least Square (OLS). The results of the study show that Indonesia has comparative and competitive advantages, but it is necessary to evaluate the results of Diamond Porter's analysis which shows the lack of quality of labor, the lack of export destination countries, the decline in the area of land for Indonesian cinnamon production, the lack of the latest technology, and the lack of Indonesian cinnamon downstream industry activities. Indonesia is also in an optimistic market and has a significant relationship with cinnamon prices, population size, and the value of the rupiah exchange rate in major export destination countries.

Judul: Photosensor producing based on ferroelectric material of Ba0,5Sr0,5TiO3 doped by Ferrium Oxide (Fe2O3) on a P-Type Silicon Substate Si (100) applied as a digital camera with a single pixel image sensor
Abstrak: Thin film Ba0,5Sr0,5TiO3 (BST) doped with Fe2O3 was grown on p-type silicon substrate (100) using chemical solution deposition (CSD). It used the solvent 2-methoxyethanol with annealing temperature of 850°C and the doping treatment Fe2O3 of 2.5, 5, 7.5, 10 % of the mass formed BST. Pure BST had the highest absorption of 600 nm of light wavelength. Additions Fe2O3 moves highest absorption in the range of 560 nm. Fe2O3 addition was strengthening thin film sensitivity to the effects of light. In general, doping Fe2O3 10% was result the best absorbance and current-voltage of BST thin film. Electrical properties of thin films BST include dielectric, photoconductivity, and dissipation energy. Based on the current-voltage (I-V) analysis, pure BST and doped BST showed photodiode properties. Dielectric values obtained in the range from 23.32 to 243. Based on electrical conductivity data and energy dissipation, BST thin films have shown photodiode characteristics and are therefore suitable as light sensors. The image sensor in a digital camera is also a light sensor. This BST thin film has been scientifically proven to be a light sensor and also it can be applied as an image sensor. This is a novelty image sensor based on thin film Ba0.5Sr0.5TiO3.
