Judul: The analysis of factors affecting employment of industries sector in east java province 2001-2011
Abstrak: Penelitian ini bertujuan untuk menganalisis faktor-faktor yang memengaruhi penyerapan tenaga kerja sektor industri di Provinsi JawaTimur dengan menggunakan data panel 37 kabupaten di Jawa Timur dari tahun 2001-2011. Variabel bebas yang digunakan adalah Produk Domestik Regional Bruto (PDRB) riil sektor industri, Upah minimum Kabupaten (UMK), dan jumlah industri di setiap kabupaten yang dianalisis. Sedangkan variabel terikat adalah jumlah tenaga kerja sektor industri. Metode analisis yang digunakan adalah analisis deskriptif dan analisis regresi berganda data panel dengan Fix Effect Model (FEM). Hasil penelitian ini menunjukkan bahwa UMK dan jumlah industri berpengaruh signifikan terhadap penyerapan tenaga kerja sektor industri di Jawa Timur, sedangkan PDRB riil sektor industri tidak berpengaruh signifikan. UMK berhubungan negatif dengan jumlah tenaga kerja sektor industri, sedangkan jumlah unit industri berhubungan positif., The aim of this reasearch is to anlyze the factors affecting Employment of Industries Sector in East Java Province using panel data from 37 regencies in east java from 2001 to 2011. The independent variable used the real Regional Gross Domectic Product (GDP) of industries sector, minimum wages, and the total of industries in east java. The employment of industries sector were used as dependent variable. The methode used descriptive analysis and regression of panel data using Fixed Effect Model (FEM). The result indicate that minimum wage and the total of industries influence the employment of Industries Sector in East Java Province significantly, while the real regional GDP of industries sector unsignificantly. Minimum wage has negatif relation and the total of industries has positive relation to dependent variable.

Judul: Determinant of Labor Absorption in the Manufacturing  Industry Sector in West Java (2015 – 2021 Period)
Abstrak: Provinsi Jawa Barat merupakan provinsi dengan populasi terpadat di Indonesia menjadi potensi besar sekaligus tantangan secara ekonomi dan sumber daya manusia dalam pertumbuhan ekonomi. Industri pengolahan sebagai leading sector perekonomian menyumbang kontribusi besar terhadap PDB nasional maupun PDRB Jawa Barat. Penelitian ini bertujuan untuk memberikan deskripsi terkait kondisi serta faktor-faktor yang memengaruhi penyerapan tenaga kerja sektor industri pengolahan di Jawa Barat dengan menggunakan data cross section 27 kabupaten maupun kota yang ada di Jawa Barat serta data time-series selama 7 tahun dari tahun 2015 hingga 2021. Alat yang digunakan adalah regresi data panel dengan Fixed Effect Model (FEM). Hasil estimasi regresi menunjukkan bahwa variabel Produk Domestik Regional Bruto (PDRB), investasi industri, dan Indeks Pembangunan Manusia (IPM) berpengaruh positif dan signifikan terhadap penyerapan tenaga kerja sektor industri pengolahan, sedangkan variabel unit industri, produktivitas tenaga kerja, dan dummy Covid-19 memberi pengaruh negatif dan signifikan. Variabel lainnya yakni upah minimum kabupaten tidak berpengaruh terhadap penyerapan tenaga kerja sektor industri pengolahan., West Java is the most populated province in Indonesia which could be a great opportunity and challenges economically and human resources for economic growth. The manufacturing industry as the leading economic sector contributes the largest to the national GDP and the GRDP of West Java. This research aims to describe the conditions and factors that affect the employment of manufacturing industrial sector in West Java by using cross section data from 27 districts and cities in West Java and time-series data for 7 years in the period 2015 to 2021. The tool used in this research is panel data regression with Fixed Effect Model (FEM). The results of the research found that the variables of Gross Regional Domestic Product (GRDP), investment of manufacturing industry, and human development index (HDI) had a significant positive effect on the absorption of labor in the manufacturing industrial sector, while the number of industrial units, labor productivity, and the Covid-19 dummy have a significant negative effect. Other variables such as district minimum wage has no significant effect on employment in the manufacturing industrial sector.

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.
