Abstract

The research about growth level and seed biomass of Rhizophora apiculata was conducted on September to November 2009 in Upang Delta area, Banyuasin Regency, Province of South Sumatera. The observation location was divided into 3 stations. The  growth level of Rhizophora apiculata seed was measured in each monitorings for three months after planting. Calculation and measured were done conducted consist of living percentage, seed growing, total of leaves and diameter of tree. Calculation biomass of Rhizophora apiculata seed was conducted by cutting seed then it was dried on the oven with temperature 105 oC for 24 hours. The living percentage of R. Apiculata was range between 46,67-73,33%. The increase height average of bud weas 0,45-0,74 cm. The average diameter of bud which have been planting for 3 months were 0,02-0,04 peaces. Biomass of R. apiculata feed lings 3 months were 21,622-33,729 gr.

Abstract

Penelitian dilakukan untuk mengetahui asosisasi jenis pada komunitas vegetasi di lahan tailing. Tailing adalah residu akhir batuan alami setelah mengalami proses mineralisasi dan berbentuk lumpur pasir. PT Freeport mengelola dan menempatkan tailing pada suatu kawasan lahan basah yang direkayasa khusus yaitu Modified Ajkwa Deposition Area (ModADA). Terdapat kawasan terpisah dalam ModADA yang tidak dipengaruhi tailing secara aktif dan relatif stabil, struktur tanah mulai berkembang dan dimanfaatkan sebagai area suksesi alami atau reklamasi disebut Tanggul Ganda. Metodologi yang digunakan adalah metode transek terdiri dari beberapa plot bujur sangkar. Parameter pengamatan adalah struktur dan komposisi vegetasi pada semua tingkat pertumbuhan (pohon, tiang, pancang, dan semai), serta kehadiran jenis pada setiap plot. Penghitungan Indeks Nilai Penting (INP) jenis dan nilai asosiasi dua jenis tumbuhan menggunakan uji Chi Square dan rumus Indeks Jacard. Hasil memperlihatkan jenis pionir Phragminthes karka dominan pada kawasan Tanggul Ganda, dan keanekaragaman jenis lebih tinggi pada area relatif kering. Nilai asosiasi untuk tingkat pohon tergolong tinggi ditemukan antara Campnosperma brevipetiolata dan Ficus benjamina, tingkat pancang ditemukan antara Neprolephis cardifolia dan Phylodendron sp. Berubahnya karakteristik biofisik lahan tailing berkaitan dengan meningkatnya kualitas tanah yang akan mempengaruhi asosiasi jenis dan keanekaragaman pada hutan suksesi.

Abstract

Research on the Morphological Diversity of Lansium domesticum Corr in South Sumatra aims to examine the morphological diversity of L. domesticum in South Sumatra. The research was conducted in April 2017 to June 2017. This research was conducted by means of exploration carried out in seven districts covering, East Ogan Komering Ulu District, South Ogan Komering Ulu District, Ogan Komering Ulu District, Musirawas District, Ogan Komering Ilir District, Muara Enim District and Musi Banyuasin District. Sampling was done using purposive sampling method. Observation of morphological diversity was done by characterization of morphology and analyzed by the descriptive method. The result of this research shows that in South Sumatera, there were two variants of L. domesticum namely L. domesticum variant duku and L. domesticum variant langsat. Morphological characters that distinguish between duku and langsat variants were found under canopy conditions, the presence of hair on top and bottom surfaces of leaves, fruit shape, fruit skin thickness, fruit taste, and the presence of sap on ripe fruit.

Abstract

Research on the diversity of rattan morphology has been conducted in three forest conservation areas in South Sumatra i.e. Bentayan Wildlife Reserve, Bukit Cogong and Gunung Raya Wildlife Reserve. This study aims to analyze the diversity of rattan morphology in three protected areas in South Sumatra. This research uses purposive sampling method by exploring the forest area. The results showed that in the Bentayan Wildlife Reserve area were found 3 species of 3 genera while in Bukit Cogong Protected Forest were found 9 species of 3 genera and in the Bentayan Wildlife Reserve area were found 5 species of 3 genera. The morphology of rattans species in the three regions have different shapes and colors of thorns on the stem, the top and the bottom surfaces of the leaves, the climbing organ and the growth nature. The same rattan species were being found in the same of two or three locations, having morphological differences in diameter and length of the stem.

Abstract

The southern Sumatera region experiences one rainy season and one dry season in a year associated with seasonal change in monsoonal winds. The peak of rainy season is occurring in November-December-January during the northwest monsoon season, while the dry season comes in June-July-August during the southeast monsoon season. This study is designed to evaluate possible influence of the coupled ocean-atmospheric modes in the tropical Indo-Pacific region, namely the El Niño-Southern Oscillation (ENSO) and the Indian Ocean Dipole (IOD) on the rainfall variability over the catchment area of the Music Basin, South Sumatera. The ENSO and IOD occurrences were reflected by the variability of sea surface temperature (SST) in the tropical Pacific and Indian Ocean, respectively. During El Niño and/or positive IOD episode, negative SST anomalies cover the eastern tropical Indian Ocean and western tropical Pacific including the Indonesian seas, leading to suppress convective activities that result in reduce precipitation over the maritime continent. The situation is reversed during La Niña and/or negative IOD event. The results revealed that the high topography area (e.g. Bukit Barisan) was shown to be instrumental to the pattern of rainfall variability. During the 2010 negative IOD co-occurring with La Niña event, the rainfall was significantly increase over the region. This excess rainfall was associated with warm SST anomaly over the eastern tropical Indian Ocean and the Indonesian seas. On the other hand, extreme drought event tends to occur during the 2015 positive IOD simultaneously with the occurrence of the El Niño events Investigation on the SST patterns revealed that cold SST anomalies covered the Indonesian seas during the peak phase of the 2015 positive IOD and El Niño event.

Abstract

Analisis struktur dan komposisi vegetasi area reklamasi kawasan pengendapan tailing PT. Freeport Indonesia (PT-FI) dapat menggambarkan keanekaragaman,kelimpahan dan dominansi jenis. Informasi ini dapat dijadikan acuan untuk memantaukeberhasilan reklamasi yang dilakukan PT-FI sehingga akan membantu dalammengambil kebijakan pengelolaan kawasan pengendapan tailing. Monitoring vegetasidilakukan melalui metode observasi lapangan pada dua area reklamasi, yaitu area Tanggul Barat Lama dan area Tanggul Barat Baru di wilayah Mod-ADA. Datavegetasi meliputi tingkat petumbuhan semai, pancang, tiang dan pohon diperolehmelalui metode transek berupa garis berpetak. Diagram profil vegetasi digambarkanmelalui transek 20 x 60 m. Selama periode penelitian bulan Mei s/d Juli 2009, untukarea Tanggul Barat Lama diperoleh spesies tingkat pohon, tiang, pancang, semai setatumbuhan bawah masing-masing sebanyak 5, 8, 24 dan 51 spesies, sedangkan untukarea Tanggul Barat Baru masing-masing diperoleh 3, 3, 13 dan 38 spesies. Diagramprofil vegetasi untuk area Tanggul Barat Lama terdiri dari 11 spesies sedangkan untukTanggul Barat Baru terdiri dari 6 spesies. Diagram profil pada kedua tanggul inididominasi oleh Casuarina equisetifolia L. Hasil yang diperoleh menunjukkan areareklamasi yang pada awalnya hanya ditanami beberapa jenis tumbuhan sepertiCasuarina equesetifolia L., ternyata dapat menyediakan habitat yang cukup baik bagiberagam jenis tumbuhan lain.
