Abstract

Robusta coffee is a coffee type found in South OKU Regency in Indonesia, and its storage process is highly susceptible to the growth of various fungal species, including fungi that produce Ochratoxin A (OTA). Therefore, this study aims to examine the fungal contamination contained in storage using polystyrene and gunny sacks for 20 and 30 days. Data were obtained from surveys, interviews, and samples from 30 farmers which stored coffee beans using polystyrene and gunny sacks in May-July 2020. The results showed that the moisture content was higher in storage using gunny sacks than in polystyrene sacks, at 16.94 ± 0.878 % and 15.99 ± 1.33%, respectively. Furthermore, 16 fungal species were present in gunny sack storage, while 14 fungal species were observed in polystyrene sacks. The percentage of OTA-producing fungi A.niger and A.ochraceus in the two stores yielded 100% and 63.3%, respectively

Abstract

Medicinal plants have been very important plants that are responsible in maintaining the health of millions of people in the world  since a very long time. Planting these crops must be carried out on a land that is suitable based on the results of a land suitability evaluation.  A framework to evaluate the land suitability for many land uses is initiated by Food and Agricultural Organization (FAO) in the late 1970’s. As the advent of smart phone nowadays becoming ubiquitous technology to solve problems in most settings, such as education, agriculture, medicine, psychology, and many others. This paper is to capitalize such advantage by converting the framework into a mobile app. This solution is hoped to help land users or planners to be more effective and efficient in evaluating their land. An algorithm is employed in the form the Rule Based System (RBS) in a way to construct the framework into bunch of rules that connect each other, resulting the conclusion of suitability. The rules itself are working on some variables, namely annual rainfall, altitude, drainage, soils’ type, pH, flood risk, fertility of the soils, soil solumn depth, etc. This study focuses on three medicinal crops only, which are candlenut, cardamom and onion to be evaluated. Data of agro climatic that were determining the suitability of the crops were developed into general and specific criteria for the plants. A usability model was studied from 40 respondents using the app. It is found that the usability of the app was in “very good” classification, with dimension scores, ranging from 3.79 and 4.22.

Abstract

The water crisis caused by floods and droughts has become an urgent problem in many regions worldwide. To address these challenges, the provision of empty spaces for rainwater harvesting has been a focus of attention as a potential solution to reduce the adverse impacts of these extreme phenomena. The objective of this study is to explore and propose effective strategies for optimizing the utilization of swamp lands for urban settlements in the Kertapati District of Palembang. The research methodology involves quantitative and qualitative analyses of hydrological data and land use on a property in Bukit Lama IB I, Palembang, South Sumatra, who has implemented the rainwater harvesting system. The hydrological data includes rainfall, roof catchment area, yard area, and rainwater accumulation rates. The results of the study show that the provision of empty spaces for rainwater harvesting can significantly reduce the risks of floods and droughts. When heavy rainfall occurs, this system can retain excess rainwater, thereby reducing surface runoff volume and slowing the flow towards rivers. Additionally, the harvested water can serve as a reserve to cope with drought during the dry season. The research also identifies several critical factors influencing the effectiveness of the rainwater harvesting system, including infrastructure design and surrounding land use. In this context, collaboration between the government, communities, and the private sector becomes crucial in implementing this system widely and sustainably. In conclusion, the provision of empty spaces for rainwater harvesting has proven to be an effective approach in reducing the risks of floods and droughts. Facing increasingly complex climate change, it is essential for communities, governments, and other stakeholders to adopt and implement this system as part of a comprehensive strategy to manage water resources sustainably and protect the environment.
