“…Sustainable local forest management in addition to local knowledge, needed to be taken into business account costs and with more definitive analysis to ensure that forest functions were maintained (Muliadi et al 2017). The cost components required to cultivate forests include the initial costs for land preparation until harvest (Florian 2014). The income component was obtained from the sale of fruit, sap, timber, and firewood.…”

Winarni B, Lahjie AM, Simarangkir B.D.A.S., Yusuf S, Ruslim Y. 2018. Forest gardens management under traditional ecological knowledge in West Kalimantan, Indonesia. Biodiversitas 19: 77-84. Local wisdom of Dayak Kodatn people in West Kalimantan in forest management shows that human and nature are in one beneficial ecological unity known as Traditional Ecological Knowledge (TEK). Former cultivation forest areas are managed in various ways, including planting forest trees, fruit-producing plants, and rubber trees until they transform into the forest garden. This research used three models, monoculture rubber cultivation (Model 1), combined rubber and camphor cultivation (Model 2), and combined rubber and durian cultivation (Model 3). This research intended to: (i) analyze the production of rubber latex and durian fruit; (ii) analyze the growth increment of camphor and durian trees; (iii) analyze the financial feasibility of rubber tree plantation, combined rubber and camphor tree plantation, and combined rubber and durian trees plantation; (iv) formulate the model of rubber cultivation. This research also used measurement methods other than field measurement, which were tree diameter and height, rubber latex and durian fruit weight, and questionnaire interviews. The maximum productions of rubber latex from three models were achieved at the age of 17 years, while maximum production of durian fruits was achieved at the age of 55 years. The maximum growth increment of camphor and durian trees were achieved at the age of 40 years. Based on NPV analysis and IRR, those three models were worthy of being cultivated. Financially, the combined rubber and durian cultivation (Model 3) was the most profitable, followed by monoculture rubber cultivation (Model 1), and lastly the combined rubber and camphor cultivation (Model 2).

Financial analysis of dipterocarp log production and rubber production in the forest and land rehabilitation program of Sekolaq Muliaq, West Kutai District, Indonesia

Lahjie AM, Lepong A, Simarangkir BDAS, Kristiningrum R, Ruslim Y. 2018. Financial analysis of dipterocarp log production and rubber production in the forest and land rehabilitation program of Sekolaq Muliaq, West Kutai District, Indonesia. Biodiversitas 19: 707-716. The Dayak community of East Kalimantan in the last decade has begun to develop production systems that integrate forest timber tree species into plantation commodity enterprises. They have become aware that the natural forest species of their surroundings such as Meranti (Shorea sp.) and Kapur (Dryobalanops aromatica) are often easier to exploit economically, and represent potentially cheaper investments, than are introduced plantation crops such as rubber (Hevea brasiliensis). This is because the price of rubber latex has decreased over the years and has ceased to give a financial return commensurate with the investment required to develop rubber as a monocrop. The research described in this paper aimed to evaluate the viability of a dipterocarp forest/rubber plantation system cultivated by people in the West Kutai District of East Kalimantan. The viability of the system was evaluated by (i) measuring its production of dipterocarp logs and natural rubber; (ii) determining the diameter distribution of its dipterocarp trees and (iii) assessing the financial feasibility of the dipterocarp/rubber system using the theories of increment production and basal area applied to the determination of Pay Back Period, Net Present Value (NPV), Net Benefit Cost (B/C) ratio and Internal Rate of Return (IRR). The research areas on which the evaluation was performed consisted of (1) a mixed population of Shorea spp. (Meranti) and rubber (Hevea brasiliensis) and (2) a mixed population of Dryobalanops aromatica (Kapur) and rubber. The growth analysis of Shorea spp. combined with rubber as well as D. aromatica combined with rubber at the planting distance of 5m x 5m showed that the maximum cycle was reached at the age of 40 years. Whereas the rubber trees in monoculture cultivation reached their maximum cycle at the age of 17 years. The optimum increment of MAI and CAI of Shorea spp. combined with rubber reached 3.61 m3 ha-1 year-1 and 3.62 m3 ha-1 year-1 respectively. The maximum increment of MAI and CAI of Dryobalanops aromatica combined with rubber reached 3.09 m3 ha-1 year-1 and 3 m3 ha-1 year-1 respectively.

“…According to Florian (2014), the cost for the forest cultivation was including the starting cost for preparing the field up to the cost of harvesting. Activities done in the tengkawang cultivation consisted of planning, field preparation, supplying seeds, planting, stitching, maintenance, and harvesting.…”

Abstract. Winarni B, Lahjie AM, Simarangkir B.D.A.S, Yusuf S, Ruslim Y.2017. Tengkawang cultivation model in community forest using agroforestry systems in West Kalimantan,. Tengkawang is the flora mascot of West Kalimantan and has long been supporting the life of people around the forest. Its fruit can be processed into fat which traded as 'green butter', 'borneo tallow', or 'tengkawang oil', which used as cocoa butter substitutes and the material for manufacturing lipstick, candle and drugs. Its wood was used as raw material for sawmill and plywood industries. Today, tengkawang tree existence is endangered and has been replaced with rubber plantations. The purposes of this research were to: (i) analyze the maximum growth increment of tengkawang; (ii) analyze the maximum production of tengkawang fruits and latex; (iii) analyze the financial feasibility of tengkawang cultivation and tengkawang combined with rubber; and (iv)formulate tengkawang cultivation model. The research used a descriptive method in survey form and interview technique by using questionnaire. The research result showed that the maximum growth increment of tengkawang which cultivated in monoculture (model 1) and tengkawang combined with rubber (model 2) were achieved at the age of 40 years. The maximum production of tengkawang fruit in model 1 and model 2 were achieved at the age of 64 years, while the maximum production of latex (model 2) was achieved at the age of 17 years. The cultivation of tengkawang by model 1 produced IRR of 12.3% and model 2 produced IRR of 12.9%. Financially, both cultivation models of tengkawang were feasible to be cultivated. Financially, tengkawang cultivation by using rubber in an agroforestry system was more profitable than tengkawang cultivation in monoculture.
