Abstract

Cratoxylum formosum (Jack) Benth. & Hook.f. ex Dyer is one of the plant species that have the potential to be developed into an antibacterial and antioxidant essential oil product. This study was conducted to determine the value of organoleptic tests and the consumers' willingness to pay (WTP) for the three variants of Cratoxylum formosum essential oil products. For the parameters of colour, hedonic test values and score tests showed good results; panellists did not mind the pure and mixed Cratoxylum formosum essential oil colours. However, for fragrance parameters, the hedonic test showed a dislike score. Most panellists disliked the strong "scent of leaves" of pure C. formosum oil. The score test showed satisfactory values, the panellists accept the fragrance of Cratoxylum formosum essential oil, but it is necessary to add a more preferred scent mixture to reduce the strong original fragrance of the oil. The cost of production of Cratoxylum essential oil is Rp.7,259.23 (USD 0.48)/mL or Rp.72,592.30 (USD 4.84) for every 10 mL. Based on the cost ofproduction, the appropriate selling value for every 10 mL of Cratoxylum essential oil is a minimum of USD 4.84.

Abstract

Kancilan Flores (Pachycephala nudigula nudigula) is an iconic bird of Kelimutu National Park. The bird has a unique characteristic with the ability to make a wide variety of song. The local people call this bird 'Garugiwa' and also 'burung arwah' or 'spirit bird' because it is small and hard to spot but has a loud chirp. Some literature mentions this bird with different scientific names. This study aimed to identify this bird to rectify this misnaming scientifically and to observes Kancilan Flores behavior, habitat, and population. Kancilan Flores is an attractive fauna for tourists. Therefore, this study also recommended potential birdwatching locations for Kancilan Flores. This study used a transect line and direct observation methods. The results showed that the estimated population size of Kancilan Flores in the Kelimutu National Park was 1,667 individuals with a population size range of 1,245–2,089 individuals. The population density of Kancilan Flores was estimated at 0.53 individuals per hectare. The Kancilan Flores is most commonly found at an altitude of 1,500–1,600 m a.s.l. Recommended areas as bird watching locations for Kancilan Flores, namely the Edelweiss Garden, Perekonde, the lower Arboretum, and the Kancilan Flores middle Arboretum. Therefore, it is necessary to protect the population of Kancilan Flores by strictly prohibiting hunting and destruction of their habitat.

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.
