Undernourishment is a threat to human health. The prevalence of undernourishment remains alarming, especially among children under five years old in many countries, including Indonesia. Nowadays, the handling of undernourishment has shifted to treatment outside the hospital, utilizing local nutrient-rich foods. At the national level, the utilization of local food resources is a part of the promotion of dietary diversification and the bioeconomy. Ready-to-use supplementary food (RUSF) refers to supplementary foods aimed at improving the nutrition of moderate acute malnutrition (MAM) children under five years old. RUSF biscuit recipes were made using local food resources available in Banten province, Indonesia. To optimize the nutritional profile of the developed RUSF, taro/talas banten were mixed with ground-nut/peanut (Arachis hypogaea L.) and mungbean (Vigna radiata) as protein and lipid sources and red rice (Oryza longistaminata) and maize (Zea mays) as carbohydrate sources, and enriched by the local banana Nangka (Musa textilia). Two formulations were selected for the pilot testing, namely the taro-peanut and taro-peanut/mungbean RUSF biscuits, made from taro Banten, cereal, peanut and/or mungbean, and local banana. The RUSF biscuit showed promising results, presenting a high level of acceptance and a macronutrient composition that meets the standards for MAM children. However, the RUSF biscuits should be fortified with micronutrient premix to fulfill the dietary requirement for the MAM children. The results of this study provide further development opportunities.
Evaluation land use cover changes over 29 years in Papua province of Indonesia using remote sensing data
(2021) Letsoin, Sri Murniani Angelina; Herak, David; Purwestri, Ratna Chrismiari
Land use/cover change (LUCC) observation and determination have been extensively discussed in natural resources management, biodiversity and ecosystem preservation, land management also climate changes studies. An evaluation of the LUCC in Merauke, the easternmost city of Indonesia, was conducted to gain relevant information in agriculture and forestry based on historical data from remotely sensed land cover data. To obtain the historical dynamics of the LUCC, a supervised classification algorithm was implemented to the Landsat images of 1990, 1996, 2009, 2015, and 2019 as well as statistical analysis Wilcoxon signed-rank. This study aims to investigate and analyze the LUCC over a period of 29 years. The results show a significant decline in the forest area by around 7% in 2019. As compared to the LUCC in 1990, agriculture sectors such as dry-land agriculture, shrub-mixed dry land and paddy field gained an area higher than 50%, while the area of the water body is a declined by 0.61 % over the period. The evaluation of LUCC will help government development plans in the protection of commodities in this Province and the promotion for biomass and bioenergy resources.
