Abstract

This paper describes the ebony (Diospyros celebica Bakh.)site characteristics in Amaro Forest,Barru District, South Sulawesi including its secondary succession to create a favourable conditions for stand establishment. Association analysis shows that a wide variety of lowland species have been identified grows together with the ebony.Physical characteristics rather than chemical fertility of soils show a great value in supporting ebony stand growth.Poor stand with low natural regeneration of these remaining fragmented forests suggest the need to apply enrichment planting and improvement cutting to increase their productivity.

Abstract

Pohon eboni (Diospyros celebica) pada hutan alam telah mengalami tekanan eksploitasi yang intensif karena kayunya memiliki nilai ekonomi yang sangat tinggi. Keadaan ini mengakibatkan popuiasi jenis pohon endemik Sulawesi ini menjadi sangat berkurang, sampai pada tingkat yang mengkhawatirkan kelestariannya. Oleh karena itu, D.celebica telah ditetapkan sebagai tumbuhan yang tergolong vulnerable species dan sebagian besar habitat tempat hidupnya ditetapkan sebagai suaka alam atau kawasan yang dilindungi khusus untuk melestarikannya. Pendekatan pelestarian eboni secara in-siiu seperti yang diuraikan di atas belumlah memadai untuk dapat dengan cepat memulihkan popuiasi dan potensi eboni.Selain itu, pendekatan pelestarian sebagaimana tersebut di atas tidak memberikan peluang bagi pemanfaatan kayu eboni pada saat popuiasi dan potensinya telah memungkinkan untuk dimanfaatkan. Untuk mengatasi hal tersebut, perlu dipikirkan beberapa pendekatan pelestarian lainnya, di antaranya adalah pelestarian secara ex-situ.Pendekatan pelestarian secara ex-situ dapat diarahkan pada upaya pengelolaan dan pemanfaatan eboni secara lestari. Namun untuk mengarah pada pendekatan pelestarian secara ex-situ diperlukan telaahan mengenai preferensi ekologis dan karakteristik fisik maupun fisiologis yang terkait dengan bentuk-bentuk pengembangannya. Telaahan mengenai kemungkinan pengembangan beberapa bentuk tanaman D. celebica sebagai upaya pelestarian secara ex-situ dipaparkan.

Abstract

This study aims to design a conservation campsite that comfortable and attractive, which is also as a place of education for the conservation of natural resources and their ecosystems. This research was conducted at the Field Laboratory of Forest Resources Conservation and Ecotourism Unhas Educational Forest. Field data collection of altititude was done by using a systemic sampling method on 358 sample points, with the distance between each sample point was 10 m. Data was processed by Digital Elevetaion Model (DEM). The results are then used to create a map of the slopes and contours. The location of tents and other camp facilities, set based on the direction of the view that shows open views, elevation position with height difference based on the height of the tent, the shape of the tent (dom and platoon), distance between tents, slope classes, other campground facilities, such as toilets, public kitchens , cultural stage, as well as activities in conservation camps such as games, campfires, and others. The results showed that conservation camps at the Field Laboratory of Forest Resources Conservation and Ecotourism,  were divided into four camp blocks. Block I accommodates eight  tents that placed in the three rows, eight tents in block II in two rows, and 23 tents in block III in a position of four rows. For block IV prepared for tent tents, with a capacity of four tents in a two-row position. The campground facilities are in the form of cultural stage, resting area, musallah, management house and public kitchen, toilet, gazebo, and sports field. The design of field learning related to conservation involves three themes, namely (a) the introduction of biological natural resources and their ecosystems, (b) the introduction of ecology, and (c) conservation area management.Key words: Field Design, Campground, Conservation Education.

Abstract

The Bulusaraung Mountain is a lowland forest and is one of the main ecosystems owned by Bantimurung Bulusaraung National Park. Therefore, this study aims to determine the species composition and vegetation structure of lowland forests in the complex of Bulusaraung Mountain. The research was conducted from April to May 2018. Data collection was carried out using a 20 × 20 meter plot placed on the Balleanging, Tokaddaro  and Tompobulu track lines based on altitude (550 m asl, 650 m asl, and 750 m asl). The result of this study show that there are 44  species were found on tree class, 65 species on  pole class,  40 species on  sapling class and  25 species on seedling class. The species composition in the study area was dominated Palaquium obovatum, Persea rimosa, Arthrophyllum diversifolium, Cryptocarya laevigata, and Engelhardia serrata, while Psychotria leptothyrsa, Antidesma bunius, Maesa ramentacea, Ficus sandpaper, Baccaurea javanica, Symplocos maliliency, Callicarpa pentandra, and Saurauia tristyla is a type of tree that differentiates at each altitude. The structure of the forest canopy layer at an altitude of 550 m above sea level consists of three canopy layers, while at an altitude of 650 and 750 m above sea level consisting only of two canopy layers. The cover of forest canopy in all sampling locations was reached 75-90%.

Abstract

ABSTRACT The contribution of non-timber forest products (NTFP) to local livelihood has been studied in Pampli hamlet Luwu Utara district South Sulawesi. This study was conducted using Participatory Rural Appraisal (PRA) Method from early September to late November 2005. Study results indicated that, although the hamlet community owned rice field and occupied hectares of farming land, their income was generated mostly from collecting NTFP. Rattan is the main species among the NTFP from where almost all of the households earn cash. A rattan collector could earn more than Rp. 1,000,000 of cash within 16 days in the forest. Wild honey, resin, and gaharu were other kinds of NTFP that are also collected by hamlet community for earning cash. Fresh water shrimp and fishes collected from the Patikala river served the major portion of protein needed by the hamlet community, while some plant species collected from the forest were used for medicines and vegetable as well. Fuelwood collected from the forest was the only source of energy for the hamlet community. Since NTFP could fill their need for cash and other living-requirements anytime they want, there was a tendency that the hamlet community did not plant their farming land intensively using crops or fruit trees.

Studi ini telah diselenggarakan menggunakan Metode Participatory Ruaral Appraisal (PRA), dari awal September sampai November 2005. Hasil studi menunjukkan bahwa, walaupun masyarakat dusun Pampli memiliki sawah dan mengerjakan lahan kering, pendapatan mereka sebagian besar dihasilkan dari mengumpulkan hasil hutan non kayu (NTFP). Rotan adalah jenis yang utama diantara NTFP dari mana hampir semua rumah tangga mendapat uang tunai. Suatu rotan dikumpulkan bisa mendapat lebih dari Rp. 1,000,000 uang tunai di dalam 16 hari di dalam hutan. Madu liar, Damar, dan Gaharu adalah jenis lain NTFP adalah juga dikumpulkan oleh masyarakat dusun Pamli for mendapat uang tunai. Udang Air tawar dan Ikan dikumpulkan dari sungai Patikala memenuhi sebagian besar kebutuhan masyarakat, sedangkan beberapa jenis tanaman dikumpulkan dari hutan telah digunakan untuk obat dan sayuran juga. Minyak kayu dikumpulkan dari hutan adalah satu-satunya sumber energi untuk masyarakat dusun Pampli. Kata Kunci: Hasil Hutan Bukan kayu, PRA, Rotan, Madu Liar, Resin

Abstract

The study aimed to analyze the pattern of ebony distribution (Diospyros celebica Bakh) and the relationship of microhabitat factors with variable density and dominance. This research was conducted in the Tombolo Resort Balocci Forest Area of Bantimurung Bulusaraung National Park in South Sulawesi Province. Data collection is carried out in a plot measuring 100 m x 100 m divided into 100 subplots measuring 10m x 10m, covering the individual number of trees and the area of the base field on each research sub-plot. Microhabitat factors include pH, marbles, soil depth, header closure, and the proportion of sub-plot surfaces covered in outcropping stones. The results showed that (1) the pattern of ebony distribution at the location of this study is clustered, (2) the correlation value of pH and density shows a negative and insignificant relationship (p>0.05), the correlation of marbles with density shows a positive and significant value (p<0.05), the closing correlation of the header, the depth of the soil with a positive but insignificant density (p> 0.05), while the correlation of the proportion of sub-plot surfaces covered in outcrops and densities showed a negative but significant relationship (p<0.05), (3) the correlation value of pH with negative and insignificant dominance (p>0.05), the correlation of the proportion of outcrop stones with negative and significant dominance (p<0.05), the correlation of heading closure, marbles with positive and significant dominance (p<00.05), soil depth correlation and positive but non-significant dominance (p> 0.05).
