Judul: Pengaruh Kinerja Logistik Terhadap Perdagangan Internasional
Abstrak: Perkembangan globalisasi membuat tingkat persaingan antarnegara semakin tinggi. Daya saing antarnegara yang berhubungan dengan perdagangan ditandai dengan sistem kinerja logistik. Penelitian ini bertujuan untuk menganalisis pengaruh kinerja logistik terhadap perdagangan internasional di delapan puluh negara observasi periode 2010-2018.Variabel yang digunakan dalam penelitian ini adalah GDP per kapita, total populasi dan aspek-aspek Logistic Performance Index (LPI). LPI terdiri dari enam komponen penyusunnya yaitu kualitas kepabeanan, infrastruktur, pengiriman internasional, penelusuran dan pelacakan barang, jangka waktu pengiriman dan kompetensi penyedia jasa logistik. Hasil estimasi dengan pendekatan analisis data panel menunjukkan bahwa variabel yang secara signifikan berpengaruh positif pada total perdagangan di delapan puluh negara observasi adalah GDP per kapita, timeliness, infrastructure, trackingtrace dan international shipments. Variabel customs signifikan namun berpengaruh negatif terhadap total perdagangan. Sedangkan variabel ukuran populasi dan quality logistics services berpengaruh secara tidak signifikan terhadap total perdagangan.

Judul: The Determinants of Logistic Performance in Asia-Pacific Economic Cooperation (APEC)
Abstrak: Peran penting logistik dalam mendukung pergerakan barang dan memfasilitasi perdagangan saat ini menjadi perhatian banyak negara, termasuk kawasan APEC. Logistik berperan dalam menjaga ketersediaan pasok, menurunkan biaya perdagangan, dan dapat meningkatkan respon permintaan pasar dengan lebih cepat sehingga dapat meningkatkan daya saing produk di pasar global. Namun, beberapa negara anggota APEC, termasuk Indonesia masih memiliki kinerja logistik yang rendah sehingga perlu ada upaya untuk dapat meningkatkan kinerja logistik. Penelitian ini bertujuan melihat pengaruh pilar daya saing global, yakni kualitas infrastruktur transportasi, dan PDB per kapita, gross fixed capital formation (GFCF), indeks persepsi korupsi, dan dummy Covid-19 terhadap indeks kinerja logistik (LPI) menggunakan regresi data panel. Data yang digunakan mencakup data panel dengan 18 negara anggota APEC selama periode 2014-2022. Hasil studi ini menunjukkan bahwa kualitas jalan, PDB per kapita, indeks persepsi korupsi berpengaruh signifikan terhadap kinerja logistik. GFCF, kualitas bandara, kualitas jalur kereta api, dan Covid-19 tidak signifikan terhadap kinerja logistik. Sementara itu, kualitas pelabuhan berpengaruh negatif terhadap kinerja logistik di kawasan APEC., The important role of logistics in supporting the movement of goods and facilitating trade is currently the concern of many countries, including the APEC region. Logistics plays a role in maintaining supply availability, lowering trade costs, and can improve market demand response more quickly so as to increase product competitiveness in the global market. However, some APEC member economies, including Indonesia, still have low logistics performance so there needs to be an effort to improve logistics performance. This study aims to see how the pillars of global competitiveness, namely the quality of transportation infrastructure, and GDP per capita, gross fixed capital formation (GFCF), corruption perception index, and Covid-19 dummy affect logistic performance index (LPI) using panel data regression. The data used includes panel data with 18 APEC member economies during the period 2014-2022. The results of this study show that road quality, GDP per capita, corruption perception index have a significant effect on logistics performance. GFCF, air transportation quality, railway quality, and Covid-19 are not significant to logistics performance. Meanwhile, port quality has a negative effect on logistics performance in the APEC region. Keywords:. logi

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.
