Judul: The Effect of Logistics Performance on Economic Growth in ASEAN Countries
Abstrak: The global market is one of the drivers of economic growth through export activities within a country. Meanwhile, the logistics sector plays an important role in global market activities. ASEAN is one of the countries that has the potential to develop logistics performance in its country. The purpose of this study is to determine the effect of logistics performance on economic growth in ASEAN for the 2010-2019 period and to encourage planning for ASEAN as a food barn. In this study, the independent variables used are investment, labor, general government consumption expenditure, and LPI. The study used secondary data and processed using panel data regression method. The results showed that all independent variables used in this study except for labor had a significant positive effect on economic growth in ASEAN. Meanwhile, the labor has a significant negative influence on ASEAN economic growth., Pasar global merupakan salah satu pendorong pertumbuhan ekonomi melalui kegiatan ekspor dalam suatu negara. Sementara itu, sektor logistik sangat berperan penting dalam aktivitas pasar global. ASEAN merupakan salah satu negara yang memiliki potensi dalam mengembangkan kinerja logistik di negaranya. Tujuan dari penelitian ini yaitu untuk mengetahui pengaruh kinerja logistik terhadap pertumbuhan ekonomi di ASEAN periode tahun 2010-2019 serta mendorong perencanaan ASEAN sebagai lumbung pangan. Pada penelitian ini, variabel independen yang digunakan yaitu investasi, tenaga kerja, pengeluaran umum konsumsi pemerintah, dan LPI. Penelitian menggunakan data sekunder dan diolah menggunakan metode regresi data panel. Hasil penelitian menunjukkan bahwa seluruh variabel independen yang digunakan pada penelitian ini kecuali tenaga kerja berpengaruh signifikan positif terhadap pertumbuhan ekonomi di ASEAN. Sementara itu, tenaga kerja memiliki pengaruh yang signifikan negatif terhadap pertumbuhan ekonomi ASEAN.

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: Sintesis dan Pencirian Kompleks Fe(III)-Kuersetin
Abstrak: Quercetin belongs to flavonols which is able to chelate metal ions. Quercetin may chelate metal ions at 3’,4’-catechol, 3- or 5-hydroxycromone sites. In this study, quercetin was complexed with Fe(III). The complex with Fe(III) ions from FeCl3·6H2O was more stable than the complex derived from Fe(NO3)3·9H2O. The quercetin was yellow in color and showed maximum wavelengths (λ􀭫􀭟􀭶) at 250 and 370 nm. The Fe(III)-quercetin complex from Fe(NO3)3·9H2O was yellowish green with 􀟣􀭫􀭟􀭶 at 280 and 420 nm, whereas that from FeCl3·6H2O was dark green with 􀟣􀭫􀭟􀭶 at 280 and 430 nm. The 􀟣􀭫􀭟􀭶 shift indicated that the complex was formed at 3-hydroxychromone site. The Fe(III)- quercetin complex was formed with 1:1 metal-ligand mole ratio based on atomic absorption spectrophotometry analysis and the X-ray diffractogram showed that the crystallinity of the complex was 37%.
