Abstract

ABSTRACTCajuput oil is one of important non-timber forest product in Indonesia, which is resulted from processing of kayuputih ( Melaleuca cajuputi Subsp. cajuputi Powell) leaves. Perum Perhutani is now managing about 24,000 hectarsof kayu putih plantation in Java and 10 units of leaves processing mills with installed capacity of 53,760 tonnes peryear. However, these mill were not optimally operation due to low leaves kayu putih production. The objective of thisstudy were: (1) to develop kayu putih leaves production model, for one leaves harvesting rotation, and (2) to developkayu putih leaves production model for one biological rotation, to determine a silviculture rotation age of kayu putihstand. Subject to field condition, number of tree, stand density, and biomass by part of tree from36 temporary sampleplot (TSP) of Age Class II at BKPH Sukun were then measured to develop kayu putih leaves production model andfrom 24 TSP of all Age Class (Age Class I - VIII) at BKPH Sukun were measured to determine a biological rotationage. The result show that Morgan-Mercer-Flodin (MMF) equation was the best model representing kayu putih leavesproduction model, with option sprout age of 7 months. Polynomial equation was a model inrepresenting kayu putihleaves production model. Abiological rotation age was estimated around 25 years (with Age Class V).ABSTRAKKayu putih merupakan salah satu hasil hutan non kayu yang penting di Indonesia. Hutan tanaman kayu putih di Jawacukup besar, diperkirakan Perum Perhutani mengelola sekitar 24.000 ha areal produktif jenis ini dan memiliki 10Pabrik Pengolahan Minyak Kayu Putih (PMKP). Namun Pengelolaannya belum optimal karena sampai saat iniproduksi daun kayu putih masih jauh dari kapasitas terpasang pabrik, yaitu sebesar 53.760 ton daun kayu putih pertahun. Tujuan penelitian adalah: (1) mengetahui model produksi daun tanaman kayu putih dalam satu periodepemangkasan dan (2) mengetahui model produktivitas daun tanaman kayu putih dalam satu daur biologis. Hasilmodel yang diperoleh digunakan untuk menentukan saat daun dipanen dan saat tanaman kayu putih diganti dengantanaman baru. Metode pengambilan data dilakukan dengan survey, pengamatan langsung di lapangan denganpengukuran plot-plot ukur sementara (PUS). Plot ukur untuk pembuatan model dalam satu daur panen dibuatsebanyak 36 PUS dan 24 PUS untuk pembuatan model dalam satu daur biologis. Model produksi daun kayu putihterbaik dalam satu daur panen adalah Morgan-Mercer-Flodin model (MMF) dan pemangkasan optimum adalah padaumur tunas 7 bulan, dimana kurva laju pertumbuhan rata-rata bulanan maksimum berpotongan dengan kurvapertumbuhan bulan berjalan. Model produktivitas dalam satu daur silvikulktuyr adalah model polinomial. Daurbiologis atau saat tanaman diganti dengan tanaman baru diperkirakan pada umur 25 tahun (kelas umur V), dimanaproduk-tivitas setelah umur ini menurun.

Abstract

ABSTRAK Model-model pertumbuhan matriks transisi telah  disusun dari  data  hasil  pengukuran ulang petak ukur permanen yang dikumpulkan dari empat blok kawasan hutan bekas tebangan di Kalimantan Tengah. Pohon- pohon dalam setiap petak dikelompokkan ke dalam 13 kelas diameter dengan lebar kelas lima cm dari 10 sampai 72,5+ cm dan tiga kelompok jenis: komersial Dipterocarpaceae, komersial Non-Dipterocarpaceae, dan non-komersial. Di dalam model pertumbuhan matriks ini, jumlah pohon dalam tegakan dan jumlah pohon pada setiap kelas diameter dari suatu kelompok jenis dimodelkan sebagai fungsi dari waktu. Model- model yang tersusun terdiri atas tiga komponen, yaitu model alih tumbuh, tambah tumbuh, dan kematian. Hasil pendugaan model menunjukkan bahwa alih tumbuh suatu jenis dipengaruhi secara positif oleh jumlah pohon jenis yang bersangkutan dan secara negatif oleh luas bidang dasar tegakannya. Peluang transisi (tambah tumbuh) dan kematian pohon suatu jenis dipengaruhi oleh luas bidang dasar tegakan dan diameter pohon. Dugaan jumlah pohon pada setiap kelas diameter kemudian diuji dengan data aktual. Hasil pengujian dengan data aktual menunjukkan bahwa dugaan struktur tegakan (distribusi diameter) dalam enam tahun tidak berbias.

Abstract

Heart rot on Acacia mangium Willd. forest stand is critical especially for mechanical or construction wood based purposes. Failure on understanding the nature and the way it get established into the tree stem may cause high economic consequences.Anticipating such a worse condition, studies on cull factor in relation to age was initiated. Eventually the study is aimed at healthy cutting cycles of the clear and purposely stand establishment. The study had been carried out at BKPH Parung Panjang, KPH Bogor. Following the cull factor measurement technique combined with the pathological rotation estimation procedures, it was found that the healthy volume was 0.0623 m and the cull factor was 31.25 %.The figures were at the age of nine years. Therefore, the pathological rotation cycle for the A. mangium stand in the area could be fitted at eight years, as being adopted so far.This is true, when the plantation is established for the production of wood, provided that the tending operation is optimal. Applying the United States Department of Agriculture (USDA) Forest Health Monitoring (FHM) indices, the general performance of the A. mangium forest stand in Parung Panjang is found to be in healthy criteria. The damage indices for all stand ages investigated varied from 2.77 (lowest) to 5.16 (highest) as compared to the 21.18 value, the possible highest FHM tree index.

Abstract

Merbau [Intsia bijuga (Colebr.) O. Kuntze] is one of valuable timber tree in south-east Asia which has been known having ectomycorrhizae (EcM) though being ignored. Identification of the ectomycorrizae is prime important for being basis of further studies. This study investigated the EcM fungi associated with Merbau by using both sporocarp morphology and EcM morphotypes. Morphological characters of sporocarps and basidiocarps of the fungi and EcM morphotypes obtained from seedlings and trees from natural and plantation stands of merbau, as well as from nurseries were compared to the description of those resulted from baiting method. Only one species of ectomycorrhizal fungus was found associated with merbau [Intsia bijuga (Colebr.) Kuntze] which has not been described yet. The fungus formed mycorrhizae with monopodial pinnate branching. The fungus was identified belonging to the genus of Scleroderma. The fungus was more common to occur beneath merbau seedlings than trees. The sporocarps may be yielded under greenhouse condition and could be cultured in MMN agar media, thus it facilitates to the production of inoculums used for further studies.

Abstract

At a landscape level, forest transitions have complex spatial heterogeneity characteristics, thus the causes, driving force, typology and specific profile characteristics need to be considered for managing and mitigating forest transition. This paper describes how the diversity of forest transition characteristics was grouped and how the characteristic of group was identified. Typology classes within water catchment areas in Riau, North Sumatera and West Sumatera Provinces, Indonesia were investigated by considering social, economic and biophysical aspects. The main study objective was to develop a forest transition typology at a landscape level. The model typology was derived from a clustering method with the Standardized Euclidean Distance. The study found that the most significant factor which successfully differentiated the typology of forest transition into two typologies was the population growth having approximately 92% of overall accuracy. The first typology (typology 1) could be categorized as rapid forest transition, while the typology 2 was categorized as slow forest transition. The study suggested that the management and mitigation of the impacts of the forest transition should be conducted by considering the landscape typology as a function of the profiles for each typology.

Abstract

Following the enactment of Law Number 23 of 2014 on the Regional Government, which superseded Law Number 22 of 1999 and Law Number 32 of 2004, now the local government has no longer holds an authority to manage state forest areas, except “grand forest park” (Taman Hutan Raya) located in their respective administrative areas. The management of production forests and protected forests (located at state forest areas) is the authority and responsibility of the provincial government, while the management of conservation forests is the authority of the central government. The success of forest management and management program activities is determined, among others, by government and local government policies and their implementation at the site level. By considering ntthe complexity of forest management, the context of decentralization, and available resources as well as constrained authority, this study aims to identify the level of importance, priorities, and main roles of district governments in forest management by applying the analytic network process (ANP) method. This study suggests that the district government could play a significant role in building social capital, which serves as a first step in developing collaborative forest management by promoting the optimization of multipurpose forests to preserve forests.

Abstract

In natural resource management, it is necessary to group regions based on the similarity of their spatial and non-spatial characteristics, to efficiency and effectiveness Therefore, this study describes the re-grouping of the twelve island clusters established by the provincial government of Maluku into more homogeneous classes. The re-grouping was carried out based on the biophysical conditions of the regions, therefore, it could be used as the basis for determining the forest management units. The results showed that the twelve designated island clusters could be simplified to eight more homogeneous island clusters with 86.4% accuracy and 82.2 validation. It also showed that there were thirteen significant changes in the grouping of clusters of the island, including the horticultural crop area (Bf) and horticultural crop production (E). Moreover, when the island cluster is reclassified into 5 classes, the grouping would be more accurate, with 94.9% accuracy and 92.4% validation. This study concludes that there are two dominant factors in the classification of the island cluster in Maluku province namely, biophysical and social.
