Judul: A Growth Analysis of Forestry Based Sectors and Its Impact on Income Distribution and Employment in Indonesia : Miyazawa Input-Output Approach
Abstrak: Forestry based sectors have role important to economy, but its problems are output of forestry based sectors have decreased during the last one decade which showed from decreasing its contribution to total Gross Domestic Product (GDP). This condition will impact on economy as a whole especially in economic growth, employment, household income and others sectors which have related. One of the strategy to increase its output by increase factors which is become sources of its output growth are consist of exsport exspansion, domestic demand, import substitution and technological change. This research is aimed to (1) analyze sources of output growth in forestry based sectors, (2) analyze impact of increasing output on household income distribution and employment, and (3) analyze linkages of forestry based sectors. This research analysis using the input-output miyazawa model. The model is extension from Indonesia input-output table. Forestry based sectors are divided into five sub sectors such as forestry, sawntimber industry, pulp industry, plywood industry and furniture industry. The results showed that sources of output growth in forestry, sawntimber industry, furniture industry and plywood industry mainly are caused by domestic demand factor, meanwhile in pulp industry is caused by exsport exspansion. Increasing output of forestry based sectors are able to increase household income and employment. Increasing income especially in low income group in rural area. All forestry based sectors except furniture industry, have strong forward linkages. Thre are three sectors which have strong backward linkages are furniture, pulp and plywood industry.

Judul: The Impact of Forestry Sector Investment on The Indonesian Economy
Abstrak: Indonesia memiliki potensi sumber daya hutan yang besar jika di lihat dari luas kawasan hutan yang mencapai 120 juta hektar. Hal tersebut dapat menjadi modal utama dalam pembangunan. Namun produktivitas sektor kehutanan dan industri pengolahan kayu cenderung mengalami penurunan sehingga membutuhkan adanya investasi. Penelitian ini bertujuan untuk mengetahui keterkaitan dan efek pengganda sektor kehutanan serta dampak investasi sektor industri kehutanan. Metode analisis yang digunakan adalah analisis input-output dengan menggunakan Tabel Input-Output Indonesia tahun 2016 klasifikasi 185 sektor yang diagregasi menjadi 25 sektor untuk analisis keterkaitan dan efek pengganda serta 18 sektor untuk analisis dampak investasi. Hasil analisis menunjukkan terdapat enam subsektor kehutanan yang memiliki kemampuan untuk menarik pertumbuhan produksi sektor hulunya, yaitu bubur kertas, bahan bangunan dari kayu, kayu gergajian dan olahan, kayu lapis dan sejenisnya, barang-barang lainnya dari kayu, gabus, bambu, dan rotan, serta kertas sementara terdapat satu subsektor kehutanan yang memiliki kemampuan untuk mendorong pertumbuhan produksi sektor hilirnya, yaitu kayu. Nilai pengganda output, pendapatan, dan tenaga kerja tertinggi baik tipe I maupun tipe II didominasi oleh subsektor kayu gergajian dan olahan serta subsektor bubur kertas sedangkan nilai pengganda impor tipe I tertinggi terdapat pada subsektor kayu gergajian dan olahan serta nilai pengganda impor tipe II tertinggi terdapat pada subsektor kayu. Dampak dari adanya investasi pada sektor industri kehutanan berpengaruh paling besar terhadap sektor industri kehutanan itu sendiri baik itu output, pendapatan, tenaga kerja dan impor., Indonesia has great potential of forestry resources because the forest’s area reaches up to 120 million hectares. This can be the main capital in the development of the economy. However, the productivity of the forestry sector and the wood processing industry tends to decline which is requiring investment. This study aims to determine the linkages and multiplier effects of the forestry sector and the impact of investment in the forestry industry sector. The analytical method used an input-output analysis using the 2016 Indonesian Input-Output Table for the classification of 185 sectors which are aggregated into 25 sectors for linkage analysis and multiplier effects and 18 sectors for investment impact analysis. The results of the analysis show six forestry sub-sectors that is pulp, building materials from wood, sawn and processed wood, plywood, other goods made of wood, cork, bamboo, and rattan, and also paper can attract growth in the upstream sector while there is one forestry sub-sector that is timber can encourage growth in the downstream sector. The forestry sectors that have the highest output, income, and labor multiplier values are dominated by the sawn and processed wood sub-sector and the pulp sub-sector, while sawn and processed wood sub-sector has the highest type I import multiplier value and wood subsector has the highest type II import multiplier value. The impact of investment in the forestry industry sector has the greatest effect on the forestry industry sector itself, in terms of output, income, labor, and import.

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.
