Abstract

Di Indonesia pohon ulin (Eusideroxylon swageri Teijsm. et Binnend.) secara alami hanya terdapat di Sumatera dan Kalimantan. Sampai saat ini penebangan pohon ulin secara tidak terkendali masih saja berlangsung, yang apabila dibiarkan akan mengakibatkan kepunahan, di lain pihak masih banyak hal yang perlu dikaji dan diteliti. Penelitian ini ditujukan untuk mendapatkan informasi tentang aspek keragaman morfologi, ekologi, pohon induk, dan konservasi ulin di Kalimantan. Hasil penelitian menunjukkan bahwa ulin memiliki keragaman morfologi yang sangat tinggi, baik berdasarkan sifat-sifat vegetatif maupun sifat generatif (terutama pada bentuk dan ukuran buah atau biji). Dari aspek ekologi, ulin tumbuh baik pada hutan tropis basah, pada tanah-tanah yang tidak tergenang air hingga pada ketinggian 500(-625) m dpl, pada daerah datar dekat sungai dan anak-anak sungai, daerah bergelombang hingga punggung bukit. Dari segi tanah, tempat tumbuh tersebut umumnya berpasir dengan pH dan unsur kimia makro (N,P,K) yang rendah. Potensi ulin sebagai pohon induk di alam tergolong rendah, yakni berkisar antara 22,11% hingga 32,30% dari populasi yang ada. Dalam hubungannya dengan konservasi, upaya yang bersifat in-situ maupun ex-situ sudah dilakukan, namun pengawasan dan pengamanan terhadap kawasan-kawasan konservasi yang bersifat in-situ harus lebih ditingkatkan.

Abstract

ABSTRAK Penelitian ini bertujuan untuk memperoleh informasi tentang beberapa aspek ekologi pohon nyamplung (Calophyllum inophyllum L.). Penelitian dilakukan di hutan pantai Tanah Merah, Taman Hutan Rakyat Bukit Soeharto, Kalimantan Timur pada bulan Juni 2009. Pembuatan petak-petak cuplikan ditetapkan secara sengaja (purposive sampling) yang masing-masing berukuran 20 x 20 m, dengan luas keseluruhan 0,44 ha. Hasil penelitian menunjukkan bahwa pada tegakan ini, selain pada tingkat pohon (INP= 90,11% ), nyamplung juga mendominasi pada tingkat tiang (INP= 140,06%) dan semai (INP= 85,85%). Sedangkan pada tingkat pancang didominasi oleh Dillenia suffruticosa (Griff.) Martelli (INP= 135,98%). Pohon nyam-plung memiliki asosiasi terkuat dengan Pouteria obovata (R. Brown) Baehni, hal ini ditunjukkan  dengan nilai indeks Ochiai, Dice, dan Jaccard yang mendekati satu. Berkaitan dengan kondisi lingkungan fisik, suhu udara pada tegakan nyamplung berkisar 25,4-31,70C, kelembaban udara 75-97% dan curah hujan rata-rata 2.000-2.500 mm/tahun, sedangkan komposisi tanahnya sebagian besar didominasi oleh tekstur pasir dengan pH 6,1-7,3.

Abstract

This research was aimed to analyze sustainability of mangrove forestmanagement at Sidodadi village. Sustainability analysis was conducted by themethod of multidimensional scaling (MDS) approach with Rap-Simaforesttechniques (rapid appraisal index sustainable for the Sidodadi mangrove forest).The result of study showed that multidimensions management sustainability wasin moderate sustainable status or it sustainability index was 55,63%. Meanwhile,that ecological and economics dimension has low sustainable status. Both socialand legal-institutional dimensions have moderate sustainable status. The resultsof leverage analysis indicated that 15 out of 33 indicators were categorized assensitivity indicators affected sustainability of mangrove management at Sidodadivillage. These sensitive indicators should be involved in increasing sustainabilityindex in the future.

Abstract

   Some small islands in Balikpapan Bay consist of dry land which may have different vegetation structure and composition. Our study was the first to uncover vegetation conditions and soil proper-ties of dry land on small islands in Balikpapan Bay, which has never been conducted before. The research was carried out on Kalawasan and Karantina islands. Information on vegetation was obtained by applying a line transect method. Data on soil properties were col-lected by setting up 3 sampling plots in each transect of vegetation. Parameters used for analysing vegetation including relative densi-ty, relative frequency, relative dominance, Shannon-Wiener diversi-ty index, evenness index, and similarity index. Meanwhile, data on soils were analysed descriptively. Trees on Kalawasan island were comprised of 241 individuals belonging to 21 species. There were 61 individuals (22 species) of trees on Karantina island. The diver-sity index of trees on Kalawasan and Karantina island was 2.55 and 2.72, respectively. The tree evenness index was 0.84 on Kalawasan island and 0.88 on Karantina island. The index of similarity for trees between the two islands was 0.21. Furthermore, the soil character-istics on Kalawasan and Karantina islands showed similarities. In general, soil in Kalawasan and Karantina islands could be catego-rised as marginal soil which was common in East Kalimantan. Con-sidering the rapid loss of tropical forests in the mainland of Kali-mantan indicates that the small islands of Balikpapan Bay play an important role in future biodiversity conservation in East Kalimantan.

Abstract

Bryophytes are a major component of the ecosystem in Indonesia. Due to their sensitiveness, the abundance and diversity of bryophytes in an ecosystem are influenced by environmental conditions. This study aimed to determine the diversity of bryophytes based on ecological parameters in the village of Blumah Kecaman Plantungan, Kendal Regency which is directly adjacent to the Mount Prau protected forest, Central Java. The data collection method used was the exploratory method and the descriptive exploratory method with survey techniques. Observation was carried out by exploring an area of  3 kilometers, every 1 km distance. An observation station was made consisting of station 1 Jiwan hamlet, station 2 Garung, and station 3 at Cengkek and Gondan springs. The specimens were identified based on taxonomic literature. Each species was collected as a specimen for further identification in the laboratory. Abiotic environment parameters such as temperature, humidity, altitude, light intensity, pH and slope were observed. The results showed that Blumah village still has high plant diversity, especially bryophytes. The more humid, the higher the place, the lower the temperature and light intensity, the more species diversity. Based on the identification results, 21 species were recorded, which includes 15 species of mosses, 4 species of liverworts, and 2 species of hornworts. The index value of bryophyte species diversity was in the medium category, and the index value of species richness and species dominance were at low levels.
