Abstract

Mount Ciremai National Park has an area of ±15,500 ha with soil characteristics at various heights and varied slope directions. This study aims to determine the characteristics of soil properties in Gunung Ciremai National Park based on slope direction and its relationship with vegetation growth. The method used in this study is a systematic sampling method based on height intervals on four slopes with depths of 0-15 cm and 16-30 cm. The results showed 1). Soil pH in all four slopes with different heights in the acid-neutral category, 2). The soil texture is classified as sandy-loam and sandy-clay loam, 3). C-organic content is classified as low-very high, 4). The content of N-Total is classified as low-high. 5). P2O5 content is classified as very low-low, 6). K content is classified as low-very high, 7). Ca content is low-very high, and 8). Mg content is classified as low to high. Significant correlation tests of soil physical and chemical properties are found on several parameters such as C/N ratio, K, and Mg.

Abstract

Potato farming is a strategic horticultural commodity that plays a vital role in the local economy and food security. However, the sustainability of potato production systems faces various challenges, including climate variability, input inefficiency, and low adoption of cultivation technologies. This study aims to identify key factors influencing the sustainability of potato farming as a basis for designing Internet of Things (IoT)-based Smart Farming technology. The analysis was conducted using the Matrix of Impacts Croisés-Multiplication Appliquée à un Classement (MICMAC) method on 15 variables representing the reinforcing dimensions, human resources, markets, and the environment. Data were collected through surveys, in-depth interviews, and Focus Group Discussions (FGDs) with potato farmers in Simalungun Regency. The results of the Matrix of Direct Influence (MDI) analysis indicate that Market Expansion, Education Level, and Price are determinant variables with high influence and low dependency. Meanwhile, Technology, Experience or training certification, and Farmer Development are included in the category of key variables with high influence and dependency, thus becoming strategic factors in the development of Smart Farming. Based on the Matrix of Indirect Influence (MII), the variables Technology, Farmer Education, Price, Experience, and Market Expansion have a strong indirect influence on the system. This finding confirms that effective IoT technology design must consider the interacting technical and socio-economic factors in potato farming systems. This research provides a scientific basis for strengthening the digital transformation of agriculture and formulating more adaptive and sustainable innovation policies.

Abstract

The sustainability of palm oil agribusiness was a strategic issue that connected economic, social, and environmental aspects in its management. Plantation practices and the palm oil industry contributed significantly to national economic growth and farmer welfare, but in reality, this activity was often associated with deforestation, land degradation, and social conflict. The importance of integrating various aspects of sustainability with agribusiness as a system from farmer perceptions produced priority elements that needed to be prioritized. The purpose of this study was to analyze the determinants of sustainable palm oil agribusiness development. This study was designed using a quantitative method with a survey approach. The sampling technique used proportionate stratified random sampling with a total of 249 smallholder palm oil farmers as respondents. Data processing was carried out using the Partial Least Square (PLS) analysis tool approach. The results of the study showed that the evaluation of modeling findings highlighted a significant influence of farmer rationality on the performance of the agribusiness system and sustainable palm oil agribusiness, as well as a significant influence of the performance of the palm oil agribusiness system on sustainable palm oil agribusiness. Meanwhile, in reality, the test results showed that farmer characteristics did not have a significant influence on any variable. Furthermore, the level of sustainability of palm oil agribusiness was perceived by farmers as more important in order from the social, environmental, technological, and economic dimensions. There was a need for cooperation and support from various parties to achieve and improve the sustainability of palm oil agribusiness, both from the fulfillment of input, production, handling of results, marketing, and supporting services to ensure its sustainability.
