Judul: Analisis Disparitas Antar Wilayah terhadap Pertumbuhan Ekonomi Provinsi Kalimantan Barat
Abstrak: Dalam proses pembangunan, Provinsi Kalimantan Barat mengalami permasalahan sosial dan ekonomi antara lain ketertinggalan dengan provinsi lain di Pulau Kalimantan serta adanya fenomena disparitas yang ditandai dengan PDRB per kapita kabupaten-kabupaten di kawasan perbatasan lebih kecil dari kabupaten di kawasan bukan perbatasan dan kota. Fenomena tersebut dipertegas dengan makin meningkatnya perbedaan PDRB per kapita antara kawasan perbatasan dengan kawasan bukan perbatasan setiap tahunnya. Kondisi tersebut akan mengancam disintegrasi bangsa khususnya stabilitas di kawasan perbatasan karena kondisi perekonomian perbatasan Malaysia lebih baik dibandingkan dengan perbatasan Indonesia. Berdasarkan kondisi tersebut, maka penelitian ini dilakukan dengan tujuan untuk mengkaji disparitas PDRB per kapita antar dan di dalam kelompok di Provinsi Kalimantan Barat, mengkaji tendensi disparitas PDRB per kapita antar dan di dalam kelompok di Provinsi Kalimantan Barat, mengkaji hubungan disparitas dengan pertumbuhan ekonomi di Provinsi Kalimantan Barat, dan mengkaji faktor-faktor pertumbuhan ekonomi pada masing-masing kelompok di Provinsi Kalimantan Barat sehingga disparitas antar kelompok semakin mengecil. Dalam rangka mengatasi permasalahan disparitas yang semakin melebar antara kawasan perbatasan dengan kabupaten/kota di luar perbatasan sekaligus mensejajarkan diri dengan provinsi lain di Pulau Kalimantan, maka perlu dilakukan percepatan pembangunan wilayah perbatasan. Untuk melakukan percepatan pembangunan wilayah perbatasan perlu dikaji secara ilmiah kondisi ketertinggalan kawasan perbatasan (khususnya dalam bidang ekonomi) dibandingkan kawasan lain di Provinsi Kalimantan Barat sehingga diharapkan pengembangan pada wilayah perbatasan sesuai dengan karakteristik fungsionalnya untuk mensejajarkan diri dengan kawasan lain di sekitarnya yang lebih berkembang ataupun untuk mensinergikan dengan perkembangan negara tetangga. Dengan demikian perlu dilakukan disagregasi wilayah untuk melakukan percepatan pembangunan di Kalimantan Barat supaya semua bisa berkembang sesuai dengan karakteristik fungsionalnya wilayah masing-masing. Disagregasi wilayah dalam penelitian ini meliputi kelompok kabupaten perbatasan, kabupaten bukan perbatasan, dan kota. Dalam penelitian ini digunakan beberapa metode untuk menjawab tujuan dari penelitian. Disparitas PDRB per kapita antar dan di dalam kelompok di Provinsi Kalimantan Barat diukur dengan menggunakan indeks Theil. Tendensi dari disparitas yang terjadi antar dan di dalam kelompok di Provinsi Kalimantan Barat dianalisis dengan analisis sigma (σ) convergence dan beta (β) convergence. Beta (β) convergence yang dianalisis dalam penelitian ini hanya konvergensi beta absolut. Dalam penelitian ini juga dihitung waktu yang diperlukan untuk menurunkan setengah dari ketimpangan pendapatan awal antardaerah (half-life of convergence).....dst

Judul: Analysis of regional development and disparities in regional development border and non-border in West Kalimantan
Abstrak: Indonesia is an archipelago that has many border areas with other countries in the region of sea and land. In West Kalimantan border there are 5 district border, namely are Sambas District, Bengkayang, Sanggau, Sintang, and Kapuas Hulu District. The border region of a country has a strategic value in supporting the success of national development, especially in the aspect of political, economic, and ecological. Border areas of natural resource potential is quite large and very high economic value, yet can be put to good use. The research was conducted in 5 districts in West Kalimantan border and aims to determine the level of development of regions, Leading sectors, the level of disparity that occurred in the border regions and the factors causing the disparity, further research will be able to provide recommendations in the process of border regional development policy. Analytical methods used to achieve these objectives include skalogram analysis, analysis of LQ and SSA, Williamson index and Theil Entropy Index, and Spatial Econometrics. The results obtained by the analysis that the level of development of border districts in the county is still dominated by 3 hierarchy and 2 hierarchy, which means that the facilities and infrastructure in almost all sub-district boundary is uneven and inadequate, both non-border districts and district boundaries. Leading sectors in the three border districts of Sambas District, Sanggau, and Kapuas Hulu District is the agricultural sector, but it is trade, hotels, and restaurants, transport and communication sector, financial sector, rental and service companies, as well as the service sector. The mining sector is a sector that has the potential to be developed in some districts such as districts Paloh in Sambas district, and some non-border districts in the District and other Kapuas Hulu. Disparity analysis results showed that there was disparity sub districts in the border counties with Williamson index value of 0.54. Disparities that occur in the form of disparities within each group the Border District Area (WKP) and the Non-Border District Area groups (WKNP). The factors that cause disparities in the border region is a factor of its own sub-regional GDP (GDP), and the surrounding district GRDP (W_PDRB), as well as factors that occur in the sub-district disparities around (W_Disparitas). Disparities that occurred in the border districts should be dealt with simultaneously and to put forward a comprehensive approach to prosperity than the approach to safety. Construction of basic infrastructure, especially infrastructure for basic social service needs should be a priority in the district border. Efforts to improve the local economy should be based on resource potential and to create linkages between sectors in one district and inter-sectoral linkages with the surrounding districts.

Judul: Elektrodeposisi Film Tipis Semikonduktor Cu2ZnSnS4 (CZTS) pada Substrat Kaca ITO
Abstrak: Semiconductor Cu2ZnSnS4 (CZTS) thin film that can be used as absorber layers on solar cell module was made via electrodeposition method. CZTS thin film was electrodeposited on the surface of a silicate glass coated with a thin layer of indium tin oxide (ITO). Deposition process was done using potentiostatic mode at room temperature with a potential of 1.05 V for 30, 45, and 60 minutes, followed with annealing the film at 2 different temperatures, 500 ºC using furnace and 180 ºC using hot plate, both treatments for 45 minutes in N2/H2S atmosphere. The X-ray difractograms were analyzed using Match 2 program and showed that the CZTS thin films had kesterit crystalline structure, with a low percentage of CZTS phase. The thin film also contained secondary phases such as Cu2S, ZnS, and SnS. The obtained CZTS thin films had a thickness between 1.039 and 1.676 μm. Absorption study showed that the band gap energy of CZTS thin films which was annealed using furnace ranged from 1.50 to 1.52 eV, whereas that annealed using the hot plate was not observed. The band gap energy value showed that CZTS thin films can be used as sunlight absorber layers on solar cell. The formation of CZTS crystal film on this investigation was effectively performed using furnace annealing process at a temperature of 500 ºC with deposition time of 45 minutes.
