Abstract

Cajuput (Melaleuca cajuputi Powell) plants are essential oil-producing plants that have ecological and economic benefits. The ideal pruning life is one way to optimize the productivity of cajuput stands. This study aims to analyze the productivity of cajuput stands at various age levels in Telawa Forest Management Unit by considering shoots, stem diameter, shoot diameter, biomass, and land suitability analysis. Data was collected by making three temporary survey plots by simple random sampling at 5, 9, 13, 17, and 21-year-old stands. The results showed that cajuput stands experienced increased productivity, as seen in stem diameter, shoot diameter, and biomass. In addition, the higher the stand density, light intensity, and humidity positively affect the total biomass, with an increase in the life of the stand. Based on the study’s results, the best cajuput productivity occurred at 17-year-old stands, with an average biomass of 1,031.43 kg/ha and an allometric equation of 18.40 kg. The decrease in cajuput productivity occurred at 21-year-old stands, 40% compared to the 17-year-old stands, and the 21-year-old stands have the lowest land index value. Despite the decline in productivity, the main effects still need to be studied over a more extended period. Keywords: biomass, cajuput, optimal lifespan, productivity

Abstract

Sustainable forest management is expected to significantly contribute to preventing climate change and supporting the achievement of the Forestry and Other Land Use (FOLU) Net Sink 2030. This study aims to determine the potential for biomass storage and carbon and economic valuation in the Arboretum of Forest Area with Special Purpose (KHDTK) Aek Nauli, North Sumatra, Indonesia. This study used systematic sampling with random start as an inventory method. The estimation of above-ground carbon uptake used general allometric equations and benefit transfer methods for the economic value of carbon. This study found 62 species of woody plants with 5 species classified as endangered according to the International Union for Conservation of Nature (IUCN) Red List of Threatened Species, namely Agathis dammara, Dryobalanops aromatica, Tectona grandis, Pinus merkusii and Saurauia bracteosa. There are 734 individuals of woody plants, including 84% in the tree phase and 16% in the pole phase, with dominant species in both phases, namely Pinus merkusii and Schima wallichii. Potential biomass and carbon stocks in the pole phase were 4.76 tons/ha and 2.24 tons/ha, respectively, while in the tree phase were 338.69 tons/ha and 159.19 tons/ha. The total estimated carbon sequestration reached 592.42 tons.CO2e/ha. Carbon stocks’ total potential economic value is IDR 2,578,832,243 (USD 164,100). Therefore, the Arboretum of KHDTK Aek Nauli is considered to have the potential to support the achievement of the FOLU Net Sink 2030 target. It is expected that the potential economic value of carbon can be converted into real value and optimized through a carbon trading scheme to offset greenhouse gas emissions and support the sustainable management of KHDTK Aek Nauli. Keywords: benefit transfer, biomass, carbon trade, climate change mitigation, economic potential

Abstract

Forest harvesting activities are forest management activity which aims to increase forest value, obtain forest products needed by the community, and provide employment opportunities for communities around the forest. One of the forest products in Java Island that is widely used because of its advantages is teak wood (Tectona grandis L.f.). One of the KPHs that produces teak wood is KPH Telawa Perum Perhutani. The implementation of Reduced Impact Logging (RIL) techniques is expected to increase productivity and obtain optimal results, as well as realizing sustainable forest management. This research aims to calculate the productivity and costs required for felling and bucking activities. Sampling was carried out using a purposive sampling method with the criteria of teak stands in the same age class at RPH Ngaren, BKPH Kedungcumleng, KPH Telawa. Data was obtained by measuring 36 samples of homogeneous teak stands in age class V and the same diameter class. Measuring working time uses the cumulative method. The research results show that the effective productivity of cutting and dividing stems in the Ngaren RPH is 1.80 m3/hour. The results of the regression analysis show that volume and effective time have a significant influence on felling and felling productivity. Volume is directly proportional to productivity while working time is inversely proportional to productivity. Cost analysis includes fixed and variable costs to obtain IDR 34,120.08/m3 results.

Abstract

Forest Farmer Group (KTH) is a platform which facilitates the establishment of enterprises by communities residing near forests. The KTH Harapan Makmur, situated in Gempolan Village, Karanganyar Regency, Central Java, has the capacity to harness both human resources and natural resources. Nevertheless, when it comes to organizational development, it lies short of being ideal. Therefore, it is imperative to offer support linked to enhancing institutional capacity. The objective of this action is to enhance community awareness of growing organizations. A community service event took place in July 2023, attended by representatives from the Gempolan Village Government, forestry extension workers, a community service team from Universitas Sebelas Maret, and members of the KTH Harapan Makmur. The activity was implemented through the organization of a Focus Group Discussion (FGD) primarily aimed at facilitating the compilation of the AD/ART. Attending participants were requested to complete a questionnaire. The activity findings indicate that roughly 40.9% of KTH Harapan Makmur members are employed as farmers, earning a monthly income ranging from less than 1 million rupiah to 3 million rupiah. Following the session, participants' understanding of KTH exhibited a percentage gain in comparison to their level of knowledge before the activity. Thus far, the primary obstacle has been the procurement of capital sources, which remain restricted. Engagement in diverse activities is expected to create possibilities for collaboration and capital acquisition to ensure the long-term viability of KTH's business.

Abstract

Social Forestry is part of community empowerment, aimed at communities living in and around forests. Banyurip Village is one of the inclave villages in the Perum Perhutani KPH Surakarta teak production forest area with a high poverty rate. The Banyurip Village community has joined the Banyurip Lestari Forest Village Community Institution (LMDH Banyurip Lestari). However, LMDH Banyurip Lestari has not yet been able to play an optimal role as expected. Therefore, so cooperation between various parties is needed as an effort to empower the community, especially women, by increasing the capacity of business institutions and/or entrepreneurship through the formation of Social Forestry Business Groups (KUPS) managed by woman. Activities carried out include technical guidance on the formation of KUPS, assistance in the preparation of AD/ART and preparation of group administration. The KUPS formed is called KUPS Kembang Pilang. KUPS Kembang Pilang is led by a chairman who is assisted by a secretary, treasurer, institutional management section, area management section, and business management section. When it was founded, KUPS Kembang Pilang consisted of 26 women domiciled in Banyurip Village. In the present community services program, the articles of association (AD/ART) of KUPS Kembang Pilang was composed. KUPS Kembang Pilang members known their rights and obligations to conduct sustainable forest management towards an economically independent village.
