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.

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.

Optimization of Mangrove Ecosystem Management in Kawasan Bungkutoko, Southeast Sulawesi as Ecotourism Area Agus Salim; Risma Illa Maulany; Ngakan Putu Oka

This study aims to determine (1) Assessment of Bungkutoko Ecotourism Conditions; and (2) Supporting factors for optimizing management, and (3) strategies for optimizing management. This research will be carried out for three months from September to December 2018 in the Bungkutoko mangrove tracking ecotourism area, Kendari City, Southeast Sulawesi (Figure 1). Identification of unknown mangrove species will be carried out at the Laboratory of Conservation of forest resources and ecotourism, Faculty of Forestry, Hasanuddin University. The results of the study: (1) Biophysical potential of mangrove ecotourism in Bungkutoko, namely 8 species of mangrove plants consisting of Avicennia lanata, Rhizophora stylosa, Bruguiera gymnorrhiza, Rhizophora apiculata, Sonneratia alba, Xylocarpus granatum, Xylocarpus stylosa, Bruguiera gymnorrhiza, Rhizophora apiculata, Sonneratia alba, Xylocarpus granatum, Xylocarpus stylosa, Bruguiera gymnorrhiza, Rhizophora apiculata, Sonneratia alba, Xylocarpus granatum, Xylocarpus moluccensis, L faustis and L faecus, and Lizar. from birds and reptiles. (2) Condition of mangrove ecotourism practices in Bungkutoko Not optimal, both in terms of education, conservation and welfare. (3) The ecotourism development strategy in Bungkutoko is in quadrant II (S-T strategy). The strategies formulated in quadrant II include: increasing the availability of educational facilities, increasing efforts to preserve the environment of mangrove forests, empowering local communities, increasing Human Resources, and working with the Kendari city government and the private sector to add infrastructure.

Hubungan Vegetasi Mangrove Terhadap Kelimpahan Makrozoobenthos di Pantai Pangkajene Ambeng Ambeng; Hazairin Zubair; Putu Oka Ngakan; Adi Tonggiroh

Mangrove ecosystem is a habitat of various fauna, especially macrozoobenthos. The changing vegetation of the mangrove ecosystem will influence the abundance of macrozoobenthos. This study was conducted in April-August 2019 and aims to analyze the dominance and density relations of mangrove vegetation against the abundance of Macrozoobenthos on the Pagkajene coast. The research location is conducted on three stations, each station is divided into two sampling areas, and on each sampling area is placed six sampling points. Data collection of mangrove vegetation is used with a multilevel plot method and Macrozoobenthos using a plot 50x50 cm. correlation the dominance and density of mangrove vegetation towards the abundance of macrozoobenthos used linear regression analysis. The results of the study gained that the mangrove vegetation dominancy positively affects to the abundance of macrozoobenthos but insignificant. Meanwhile, the density of mangrove vegetation significantly negatively affects to the abundance of macrozoobenthos.

Analisis Mikrohabitat Eboni (Diospyros celebica Bakh.) pada Kawasan Hutan Tombolo Resort Balocci Taman Nasional Bantimurung Bulusaraung Provinsi Sulawesi Selatan Puspa Sari; Risma Illa Maulany; Ngakan Putu Oka

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).
