Abstract

This paper identifies the plant species used traditionally by Karo people in North Sumatra, to cure diabetes, analyses the cultural significance index of those plants for the Karo, and clarifies phytochemical contents of the plants. Data were collected using survey method from selected respondents (n=54) based on their knowledge and practices in utilising medicinal plants to cure diabetic disease. Index of Cultural Significance (ICS) of plants was determined using the method proposed by Turner. Results showed that twelve woody plant species have been used to cure diabetes: loning leave (Psychotria sp.), kacihe leave (Prunus accuminta Hook), umbrella tree leave (Maesopsis eminii Engl), mutamba leave (Guazuma ulmifolia Lamk), cepcepan leave (Villebrunea subescens Blume), pirdot/cepcepan lembu leave (Saurauia vulcani Korth), raru bark (Cotylelobium melanoxylo), breadfruit leave (Artocarpus altilis), salam leave (Syzygium polyanthum Wight), mahogany seed (Swietenia mahagoni (L.) Jacq), cinnamon bark (Cinnamomum burmani), and yellow bamboo rod (Bambusa vulgaris Schrad). Five of those plants: loning, umbrella tree, mutamba, raru and salam have the highest cultural significance level. These five plants are highly needed in large quatities by the Karo people, so their availability in the forest should be securely conserved and protected. The plants used contained alkaloids, flavonoids, phenolics and terpenoids which can help to lower blood sugar level.

Abstract

Batak Toba community who live in the surrounding forests utilise forest-fruits that grow around their settlement. This research aims to describe the important value of the forest fruits using the Local Users Value Index (LUVI) assessment as most of the fruits have not yet been traded. The research was conducted in Simardangiang and Sitoluama Villages in North Tapanuli Regency, 2015. Data collection was done by interviewing 65 respondents selected purposively based on gender and age classification. The results showed that there were 29 species of forest fruits utilised by the community. They were categorised into four utilisation types: fresh fruit, flavouring fruit, processed fruit, and medicines. In Simardangiang Village, the five most important fruits were kapundung or menteng (Baccaurea racemose) (0.56), hopong (Macaranga lowii) (0.52), sotul, santol or sentul (Sandoricum koetjape) (0.48), harimonting or kemunting (Rhodomyrtus tomentosa) (0.47), and habo or kabau (Archidendron bubalinum) (0.42). Meanwhile, in Sitoluama Village, the five most important fruits were kapundung (Baccaurea racemosa) (0.50), hopong (Macaranga lowii) (0.41), sihim or rotan manau (Calamus manan) (0.32), handis or gamboge (Garcinia xanthochymus) (0.32), and mobe (Artocarpus dadah) (0.19). The numbers in parentheses are the important value based on LUVI. The forest fruits that have domestication potency are kapundung (Baccaurea racemose), hopong (Macaranga Iowii), sihim (Calamus manan), handis (Garcinia xanthochymus), mobe (Artocarpus dadah), harimonting (Rhodomyrtus tomentosa), sotul (Sandorium koetjape) and habo (Archidendron bubalinum).

Abstract

Sustainable peatland management must consider the social, economic, and environmental conditions of surrounding communities. Balancing these three pillars is essential for preserving the peatland's functions, which support the lives of various organisms dependent on the ecosystem. This research focuses on the behaviours of communities around peatlands in the Block C Peatland Management Unit (PMU) in Pulang Pisau Regency, Central Kalimantan. It investigates the social and economic variables influencing environmental behaviour in peatland management and utilization. Employing two methods-Participatory Rural Appraisal (PRA) and survey – this research aims to collect comprehensive data. Data processing is conducted by using tabulation and statistical inference. The PRA includes tools like village historical timelines, transects, seasonal calendars, and livelihood preferences, while the survey uses semi-structured interviews to assess individuals’ characteristics, perceptions, and participation in peatland management. The study reveals that villages encounter several challenges, including insufficient agricultural support, susceptibility to flooding, restricted access to clean water, and poorly functioning irrigation systems. Climate change has disrupted the dry season, resulting in lower rubber sap production. The limited availability of land for rice farming and a decreasing interest in forestry products are also significant concerns. The communities must shift their agricultural practice to adapt to climate change. While most respondents acknowledge the ecological importance of peatlands, greater involvement in their management is still needed. This underscores the need to enhance community capacity for peatland restoration and conservation. In conclusion, the findings stress the importance of incorporating social factors into peatland preservation efforts to foster environmental sustainability.
