Abstract

Red Jabon (Anthocephalus macrophyllus (Roxb.) Havil.) is one of the fast growing species that became priority to be developed in South Halmahera Regency, North Maluku Province. Currently the red jabon has become “Local Superior Crops” in North Maluku. One of IUPHHK in South Halmahera which develops red jabon is PT. Telagabakti Persada. The purpose of this study was to determine the best growth of red jabon seedling on urea fertilizer application. The study was conducted at PT. Telagabakti Persada, South Halmahera. The treatments of urea fertilizer were 0 g,  0.25 g, 0.50 g, 0.75 g, and 1 g. The results showed that the urea 0.25 g  fertilizer treatment resulted in the best growth of red jabon seedlings.Key words: Red Jabon, Nursery, Growth of seedling, Urea

Abstract

One of the community who have hereditary uses traditional medicine in the form of herbs is the Indari village community, West Bacan District, South Halmahera Regency, North Maluku. Until now, there has been no study regarding the types and parts of plants used for traditional medicine in Indari Village. The purpose of this research was to describe the types of plants and their parts that were commonly used as traditional medicine by Indari villagers. The data was clloected by means of an explorative survey, namely interviews and direct observations in the field. Interviews were aimed at custom leader, sandos/healers, as well as people who used or were familiar with medicinal plants. The results showed that there were 18 types of plants used by the Indari community as traditional medicine. These types namely Mengkudu (Morinda citrifolia), Jarak merah (Jatropha gossypifolia L), Kapas (Gossypium hirsitum), Gandarusa (Justicia gendarussa), Awar–awar (Ficus septica), Ketapang (Terminalia catappa), Waru (Hibiscus tiliaceus), Sirsak (Annona muricata), Kembang pukul empat (Mirabilis jalapa), Mahkota dewa (Phaleria macrocarpa), Kelapa (Cocos nucifera), Tapak kuda (Ipomoea pescaprae), Kedondong (Spondias dulcis P.), Langsat (Lansium domescitum), Mangga (Mangifera indica), Turi (Sesbania grandiflora), Mayana (Coleus artopurpureus), dan Kumis kucing (Orthosiphon aristatus). Plant organs were used are leaves, fruit, roots, bark, stems and leaves. Plant organs that are often used were the leaves.

Abstract

The development of nutmeg (Myristica fragrans Houtt) community forests needs to be supported by high-quality seed procurement, both physical, physiological, and genetic quality. Physically it can be done by morphological analysis in the form of length, diameter, and weight of seeds. Meanwhile, to determine the physiological quality, one of which is by observing germination. This research aimed to identify the morphology of seeds and germination of nutmeg (M. fragrans Houtt.) from different seed sources in the development of nutmeg community forests in Bacan, South Halmahera. The results showed that the morphology of nutmeg seeds in the shape, color, and skin surface variables at the three locations (Amasing, Papaloang, and Babang) obtained the same results, namely oval, brownish-black and shiny. Whereas in seed length, nutmeg from Papaloang has a longer seed size than seeds from Amasing and Babang. In the germination parameter values, seeds from Papaloang were found to have the highest value, namely the percentage of germination (K = 35%), peak value (PV = 0.56), average daily germination (MDG = 0.56), germination value (NK = 0.31 ).

Abstract

Non-timber forest product commodities in Gunung Silanu Village are cashew, turmeric, candlenut, coffee, cocoa, ginger, and galangal. Among these commodities, cashew and turmeric are the most developed commodities. However, this study is focused on the cashew (Anacardium occidantale). Cashew seed processing in Gunung Silanu Village only reaches into the drying stage, even though there was a peeling tool available. This condition makes farmers market their cashew seeds directly. There is a problem that frequently encountered in marketing cashew seeds, namely the unconstant price of cashew seeds. This certainly affects farmers' income. Therefore, a study related to marketing channels for cashew nuts in the village of Gunung Silanu to see the price level at each marketing institution is needed. The purposes of this study were to determine marketing channels, analyze marketing margins, and marketing efficiency levels of cashew nuts (Anacardium occidentale) was a non-timber forest product at community forestry in Gunung Silanu Village. The results showed that there were two marketing channels. The first marketing channels were from farmers to large traders in the village of Gunung Silanu then to large traders in Jeneponto Regency. The second marketing channels were from farmers to small traders and large traders in Gunung Silanu Village then to large traders in Jeneponto Regency. The marketing margin of the big traders in the first channel is 15.6% with an efficiency level of 0.48%, while in the second channel is 13.4% and 11.3% for small traders and big traders respectively, so the total marketing margin is 23.3 % with an efficiency level of 0.48%. The most efficient channel is a channel with small costs, large margins, and a short marketing channel which is the first channel.
