Abstract

A special-purpose forest area (KHDTK) is the forest area which the purposes are for teaching and research activities. One of the research conducted in KHDTK Wanagama was examining the planting of superior Teak from breeding (jati Mega). The growth of clonal teak data can also be assessed for its carbon stock. Hence, the purpose of this research was to determine the potential of biomass and carbon stock in the Jati Mega stands at KHDTK Wanagama, Yogyakarta. The research was carried out using a non-destructive method which used the allometric equation Bt = 0.0149(D2.H)1.0855. Carbon value was calculated as 50% of the total biomass. The results showed that after 17 years of planting Jati Mega, the stand density was 665 trees/ha, carbon storage was 59.98 Mg C/ha, and carbon uptake was 220.11 Mg/ha (CO2-eq). The total value of biomass, carbon stock, and carbon dioxide removal by Jati Mega stands at KHDTK Wanagama was in the medium category. The advantage of this research is for understanding the environmental services of jati Mega as a forest carbon stock. Information on forest carbon stock can be used as basic data for forest management as climate change mitigation.Keywords: superior teak, climate change mitigation, carbon accounting, environmental services

Abstract

Kabesak (Acacia leucophloea) and angsana (Pterocarpus Indicus) are native plant species of Timor Island, which can be used for various purposes such as wood for construction and furniture. Efforts to cultivate these seeds need to be understood, especially by trying to use the technique of soaking seeds and watering using liquid organic fertilizer (POC) banana pseudo-stem. This study aims to determine the effect of POC banana pseudo-stem on the germination and growth of kabesak and angsana seedlings. This research is an experimentalresearch, with a completely randomized design method. There are 4 treatments of POC banana pseudo-stem concentration (25%, 50%, 75%, and 100%) and control (POC 0%). Observations of this study were carried out on germination, seedling height and number of leaves of kabesak and angsana seedlings. Data were analyzed using analysis of variance (Anova) and continued with Duncan Multiple Range Test (DMRT). The result showed that applying POC banana pseudo-stem affected germination and seedling height of kabesak, as well as germination, seedling height and the number of leaves of angsana. The growth parameter that was not affected by organic fertilizer watering was the number of leaves on the kabesak seedling. Treatment with 100% banana pseudo-stem fermented concentration was the most optimal in increasing germination, seedling height, and number of leaves of kabesak and angsana seedlings.Keywords: germination, liquid organic fertilizer, number of leaves, seedling height

Abstract

Forest degradation leads to forest fragmentation and changes in land cover on a landscape. These changes vary considerably between landscapes. This research aims to determine the effect of land cover on the diversities and potential carbon storage. Parameters measured on 6 types of land cover including: old plantations, young plantations, old shrubs, bamboo, plantation forests, and secondary forests. The size of the plot was 1 hectare consisted of 16 observation sub-plots for the measurement of saplings, poles, and trees. Diversity parameters were measured such as species and density, also ecological indices such as diversity, dominance, and evenness of the species. The allometric model was used in predicting the biomass of each land cover. The results showed that secondary forests had considerable diversity of species at the level of poles and trees, while old plantations were arranged by the most diverse poles. This condition was indicated by a diversity index of more than 2.5 for all regeneration levels.  Young and old plantation had a diversity index approaching secondary forest for poles so that forest management has been able to improve the species composition resembling their natural conditions.  Based on the potential for carbon/biomass storage, old plantations and secondary forests had a potential of 200 tons/ha or close to carbon storage of 100 tons/ha. The results of diversity analysis showed the potential of carbon storage were affected by land cover for trees and total (P value <0.00). Average carbon storage at old plantation and secondary forest were not different with results of Duncan’s test. Based on the parameter measurements, proper forest management will be able to increase and/or maintain the species diversity and carbon storage in certain landscapes.

Abstract

This study aims to mapping the business models of rattan woven craft venturess in Gohong Village, Kahayan Hilir District, Pulang Pisau Regency, Central Kalimantan. This research is a qualitative research with a case study technique. The analytical method used is the Business Model Canvas (BMC) approach with 9 (nine) block elements. The research results showed that the customers of the rattan business were segmented markets which were divided into three groups, including demographic, geographic and psychographic. The propositions of value that given were the quality, and variety of types and motifs of the products. Additionally, marketing channels were carried out both directly and indirectly by using several market players. The customer relationship developed in the form of personal assistance; meanwhile, revenue streams were derived from the product’s sales. Key resources consist of physical assets, group-owned capital, and trained human resources. The mainactivities in the rattan weaving craft business consisted of rattan cultivation, processing of raw rattan for ready-to-weave, weaving of the rattan, and selling of the products. The key partnerships included manufacturers of raw materials , sewing equipment shops, and synthetic leather shops. Finally, the cost structure included several costs for suppliying raw materials, transportation, communications and production equipment. The positive business model elements include broad market segments, quality products and trained human resources that must be maintained and developed. The negative business model elements such as limited capital and raw materials must be resolved.

Abstract

This study examines natural regeneration of tropical peat swamp forest after fire. The study area is located in Merang Peat Swamp Forest (PSF) in Musi Banyuasin District. Merang PSF is situated over a large peat dome that stores huge amount of carbon. 23 sample plots were established in the area burned in 2015. The regeneration of understorey, seedlings, and saplings was recorded in each plot. Meanwhile, peat depth and its maturity were identified to determine the soil characteristic of study area. After 3 years of fire, the area already covers densely by understorey mainly pakis udang (Stenochlaena palustris), pakis tanah (Nephrolepis exaltata), and resam (Gleichenia linearis) with depth of root zone reach about 40 cm in some plots. The native peat swamp species showed minimal regeneration during third years after fire due to understorey covering and limited number of surviving trees. The natural regeneration of woody species was dominated by bangun-bangun (Melicope glabra) and sepongol (Evodia sambuciana) which were calculated about 371 saplings/ha and 200 saplings/ha respectively. Those all two species also founded in the seedlings stage. The peat depth varied from 0.32 m to 4.71 m with peat maturity is dominantly hemic in the subsurface. This regeneration information provides useful indications for restoration options, which could be done by assisted natural regeneration
