Abstract

This study aims to determine whether there is sigma convergence and beta convergence in Indonesia, to determine the effect of electricity infrastructure, human development, and ICT on convergence of economic growth, and to determine the scenario that can accelerate economic growth in Indonesia. The data used in this study is secondary data. The methods used are convergence analysis, panel data regression analysis, and dynamic system approach. The results showed that there was sigma convergence and no beta convergence in Indonesia in 2013-2022. Electricity infrastructure, human development, and ICT have not been able to encourage convergence of economic growth with electricity infrastructure having a significant negative effect, human development having a significant positive effect, and ICT having an insignificant negative effect. Scenarios that can be done to accelerate economic growth are structural scenarios and parameter scenarios.

Abstract

Kampung Ciwaru, Desa Arjasari Kabupaten Bandung merupakan kawasan yang sangat potensial dengan sumber daya tanaman untuk ecoprint. Kegiatan Pengabdian Kepada Masyarakat (PKM) di daerah ini bertujuan untuk pemberdayaan masyarakat dengan mengajarkan teknik ecoprint menggunakan pewarna alami lokal. Pelatihan ini melibatkan 15 peserta sebagai perwakilan kelompok karang taruna. Beberapa tanaman lokal yang  di eksplor untuk pewarna alami ecoprint di antaranya: daun kopi, daun mangga, daun jati, daun ketapang dengan variasi warna yang dihasilkan: hijau, merah dan abu-abu. Sedangkan motif daun yang diunggulkan dari daerah ini yaitu  daun singkong, daun afrika, daun jati serta bunga-bunga yang banyak tersedia di sekitar. Indikator hasil terukur meliputi peningkatan keterampilan peserta, pemahaman yang meningkat 74,16% setelah evaluasi kegiatan serta adanya 50 produk ecoprint yang layak jual berupa kain, pasmina, tas, outer dan topi yang dipasarkan melalui galeri "Ciwaru Ecoprint".  Kontribusi keberlanjutan terletak pada pengembangan ekonomi kreatif ramah lingkungan, memperkuat ketahanan ekonomi melalui kreativitas dan inovasi berbasis ecoprint.

Abstract

Economic growth is one of the important indicators used to measure the country's development. The participation of Indonesia, Philippines, and Thailand in an inter-state or ASEAN cooperation encourages economic integration. The existence of economic integration then encourages the existence of international trade and capital inflows from outside the territory of the country. Investment is one of the factors affecting economic growth. International trade and stock market developmnet is one of the factors of economic growth for developed countries, while ASEAN 3 is criticized as a developing country.The purpose of this research is to know the causal relationship between international trade and economic growth. And know the causal relationship between growth of stock market with economic growth in ASEAN 3. This study variables of international trade, stock market growth, and economic growth. The data used are annual panel data from 2000 to 2015. Using Granger causality analysis. The results of the study show a bidirectional linkage between international trade and economic growth and there is no mutual relationship between stock market growth and economic growth in ASEAN 3. Keywords: Economic Growth, International Trade, Stock Market Growth, Granger CausalityJEL classification : C23, F15, O1

Abstract

Indonesia has great potential to produce Nickel Oxide due to the abundance of Ni resources that can be used for the manufacture of SOFC anode components. Ni-YSZ which is a mixture of metal and ceramic is widely used SOFC anodes. Ni was selected because it exhibits high electrical conductivity and serves as an internal reforming catalyst. In this study, the characterization and manufacturing of Ni-YSZ-based half cells using domestic NiO were conducted. The stages of half cell fabrication begin with the mixing of solid and liquid materials and, the process of milling, sonication, degassing, tape casting, and sintering. The manufacture of half cells was carried out by adding an anti-foam concentration with a variation of 0.4; 0,6; and 0.8%. The optimal percentage composition was 0.4% anti-foam variation with a visual appearance that was not cracked, slightly curved and posed a pore size of 0.779 μm. The results of the domestic NiO characterization of imported NiO showed greater element percentage values and viscosity values, a slightly curved half cell visual appearance, good electrolyte density, and porosity values that were not in accordance with the range.

Abstract

Butterfly pea flower (Clitoria ternatea L.) has been used in Indonesia as a natural dye in food and cosmetics due to its varying colors, which depend on the acidity (pH) of the environment. The vibrant colors are attributed to the presence of anthocyanin compounds. This study optimized the anthocyanin extraction process from dried butterfly pea flowers using the Microwave Assisted Extraction (MAE) method. The variables tested included different concentrations of hydrochloric acid (HCl) at 0.01%, 1%, 2.5%, 3%, 3.5%, and 3.75% in 96% ethanol, as well as extraction times of 3, 6, 9, 12, and 15 minutes. The optimum extraction conditions identified were a HCl concentration of 3.5% in 96% ethanol with an extraction duration of 12 minutes, which yielded an anthocyanin concentration of 116.89 ppm.The FTIR analysis confirmed the similarity in functional groups between butterfly pea flower extracts and blackberry fruit extracts, highlighting the potential of butterfly pea flowers as a reliable anthocyanin source
