Abstract

This article examines the state of education in Indonesia in 2023, focusing on both the challenges and opportunities facing the system. Education in Indonesia has undergone significant transformation over the past decade, but several barriers remain, such as disparities in access, quality, and infrastructure between urban and rural areas. Despite these challenges, recent reforms and the increased use of technology have provided promising avenues for improvement. The study analyzes the national education policies, including the impact of the Merdeka Curriculum, and evaluates the role of digital learning platforms in addressing the educational needs of Indonesia’s vast population. Additionally, the article highlights key issues such as teacher training, student engagement, and education for sustainable development. By examining both the progress made and areas requiring further attention, this paper offers a comprehensive view of the Indonesian educational system in 2023. The findings suggest that while substantial improvements have been made, systemic inequities and the rapid pace of technological integration pose both challenges and opportunities for educators, policymakers, and students alike.

Abstract

The purpose of this research is to determine the supply chain losses caused by fluctuations in the selling price of Fresh Fruit Bunches (FFB).  The method used is to conduct direct surveys with palm oil Fresh Fruit Bunch (FFB) traders and end consumers at Palm Oil Mills in nine sub-districts in Labuhanbatu Regency.  The planned number of samples to be interviewed is 800 respondents, consisting of 784 Collecting Traders and 16 SMEs, with a total of 256 respondents successfully interviewed.  The research results explain the factors influencing the fluctuation of TBS purchase prices at the supplier level, namely the lack of transparency in TBS selling prices from Palm Oil Mills to traders and from traders to farmers.  The findings also suggest that the local government should establish a special institution that can provide information on palm oil prices released by the government through the North Sumatra industry office. In addition, we recommend that the North Sumatra government involve district governments and other stakeholders in the context of the triple helix in sustainable development, considering the imbalanced needs and productivity in implementing national strategic programs.  The next research question is about the sustainability of small-scale oil palm farmers, considering the continuous growth of oil palm.  Policymakers in key stakeholder institutions need to design strategies to manage global disruptions in palm oil trade, particularly by involving farmers in national strategic programs, one of which focuses on concentrating development on palm oil downstreaming.

Abstract

Climate is an important factor in the growth and productivity of coffee plants. This research aims to determine the climate conditions regarding the use of shade on the development and productivity of coffee plants. This observation was carried out on agroforestry coffee plantations in Kare District, Madiun Regency. The coffee plants observed were 4 to 6 years old, and the shade used in the observations was Gamal, Dadap, and Sengon trees. Thus, based on the results of observations carried out over four months, it was found that the highest results were in Sengon stands, with an average of 27.2-27.7°C in January and March in terms of air temperature. Meanwhile, the highest observed humidity occurred in the first month and January at 76%. The highest wind speed occurs in April at 4 -5 km/hour. The highest intensity of light produced occurs in April at 8005 LUX. The results of these observations prove that the use of shade plants does not significantly affect the production and growth of coffee plants.
