Pandam Gadang has tropical forests which become the habitat of Rafflesia (Rafflesia arnoldii) which grows as a parasite of Tetrastigma (Vitaceae). Study on R. arnoldii is needed since its population continuously decrease as a result of habitat destruction of its host. The aim of the study was to determine habitat conditions, vegetation structure, and characteristic of the host species of Rafflesia; to identify environmental factors, and determine the Rafflesia habitat suitability in Pandam Gadang Koto Tinggi Village, West Sumatra. Analysis of vegetation in the habitat where Rafflesia grows using a circular plot. The number of individuals Rafflesia found was recorded and completed with observations of its morphology. Micro-climate measurements were carried out together with data collection in the field. Flower morphological analysis was descriptively presented. Environmental parameters were-processed with Canoco software 4.56 using Canonical Correspondence Analysis. Habitat suitability was analyzed using Maximum Entropy. The 17 Rafflesia individuals found on Pandam Gadang were R. arnoldii, known as "Cendawan Biriang", living parasitically on Tetrastigma leucostaphylum. The results of analysis of vegetation in the Rafflesia habitat showed that there were 250 individual plants consisting of 42 species and 21 genera. Seedlings most dominant was Lauraceae, belt were dominated by Moraceae, Meliaceae, and Euphorbiaceae. Trees were dominated by Euphorbiaceae, Moraceae, and Meliaceae. Existence and survival of R. arnoldii depended on soil pH 7-7.8, environmental humidity 83-91.8 % and distance from the nearest river 3-27.8 m.

Rambutan (Nepelium lappaceum) is one of tropical fruit plant that poses high morphological character, both cultivated or wild plants. The exploration of Nephellium in Riau Province had indicated 3 variations of wild Nephellium (Mone, Tunyiang dan Rambutan Hutan). The aim of this study was to examined the phytochemical contents of fruit from three wild Nephellium from Riau Province. Samples used in this study were three fruit parts (pericarp, aril and seed). Phytocemical tests were conducted qualitatively for alkaloid, terpenoid, steroid, flavonoid, saponin and tannin. The result showed that each fruit part had different phytochemical contents. Alkaloid was only found in aril of all wild Nephellium (Mone, Tunyiang dan Rambutan Hutan). Terpenoid and saponin were found in all fruit parts, while saponin was absent in all fruit parts from three wild Nephellium. ditemukan pada semua bagian buah dari ketiga buah rambutan liar. The result of this study provides additional information of phytochemical content of wild N. lappaceum.

Meliponiculture emerged at Tanjung Sari, a village in Kepulauan Meranti Regency, Riau Province, in 2016 and has been growing thereafter. According to our observations there were at least three main obstacles faced by colony owners at this village, i.e. colony loss, low honey production, and marketing-related issues. We attempted to address these issues through a participatory program involving colony owners of the village. Colony loss had been mainly caused by swarming and mortality and was believed to have been triggered by inappropriate conditions of the maintenance (such as too much exposure to the sun and rain as well as unrepelled diturbances by other animals. Such conditions had also been associated with low honey production. Therefore we encouraged villagers to improve the conditions by providing supporter and roof for their colonies. In regard with marketing issues, we encouraged villagers to establish a honey cooperative under BUMDES, which should regulate honey price, absorb the produced honey, and also handle its marketing to outer counterparts. In addition, the cooperative should facilitate communications between members and information disemination, and mediate negotiation with potential buyers. The benefits gained by participants were: (1) the improvement of technical knowledge of colony maintenance; (2) the improvement of colony maintenance quality that would reduce risk of colony loss; and (3) the establishment of a cooperative that would be a body that would facilitate the necessities previously mentioned. The present paper describes the processes and results in details.
