This study also shows that causes of poverty in the Western and Eastern Indonesia is different. Poverty in the Western Indonesia caused high population density especially in Java and Bali with education remains low and is predominately dependent on primary agricultural sector as the main source of livelihood. Poverty in the Eastern Indonesia caused lack of populations and inadequate availability of infrastructure. The difference may be the cause of poverty as proof that poverty reduction programs that are not effectively tackling poverty homogeneous. (3). Poverty reduction programs in the Western Indonesia can be done with transmigration and agro-industry business development, while in the Eastern Indonesia by increasing the number of population and infrastructure.

Judul: The Problem of Poverty in Central Java Province and Policy Suggestions to Reduce It
Abstrak: Provinsi Jawa Tengah masih berkutat dengan masalah kemiskinan yang tinggi. Provinsi Jawa Tengah menjadi salah satu provinsi di Indonesia dengan penduduk miskin yang tinggi di Pulau Jawa pada tahun 2021. Penelitian ini bertujuan untuk menganalisis masalah kemiskinan di Provinsi Jawa Tengah serta saran kebijakan untuk menguranginya. Penelitian ini menggunakan regresi data panel 35 kabupaten/kota di Provinsi Jawa Tengah tahun 2017-2021. Metode yang digunakan adalah metode analisis kualitatif deskriptif dan kuantitatif dengan analisis regresi data panel dengan Fixed Effect Model (FEM). Hasil estimasi penelitian menunjukkan bahwa variabel pertumbuhan ekonomi, jumlah penduduk, tingkat pengangguran terbuka, indeks pembangunan manusia, dan rata-rata lama sekolah berpengaruh signifikan terhadap kemiskinan di Provinsi Jawa Tengah. Hal ini perlu diatasi dengan kebijakan program dari pemerintah pusat maupun pemerintah daerah untuk dapat mengentaskan jumlah penduduk miskin yang masih tinggi. Berdasarkan penelitian ini dapat disarankan bahwa kebijakan yang dilakukan untuk menurunkan jumlah penduduk miskin melalui pengendalian jumlah penduduk dengan program keluarga berencana., Central Java Province is still struggling with the problem of high poverty.

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.
