Abstract

Mangrove is a unique ecosystem that has complex biotic and abiotic components. Soil and water microorganisms have function as decomposer in mangrove forest ecosystem.  This paper studies the soil and water microorganisms diversity, their potential, function in ecosystem and their role as environmental parameters in mangrove area of Teluk Kelumpang, Selat Laut and Selat Sebuku Natural Reserve (Kelautku Natural Reserve).  Data of soil and water microorganisms were recorded from soil and water samplings then analyzed in the laboratory.  Results show that benthos in Selat Sebuku figure the highest diversity index.  Anadara granosa  is one of the common benthos found in Selat Sebuku.  In contrary the phytoplankton in Selat Sebuku is the lowest value compared to the other two locations, due to the settlements in the locations and it was suspected that Selat Sebuku has a relatively larger wave exposure than the two other locations.  In addition, input of organic matters from the settlements in Teluk Kelumpang and Selat Laut is also effected  by the growth of  phytoplankton.  Cyanophyta found in Teluk Kelumpang and Selat Laut was genera of Oscillatoria that showed high tolerance genera to  the environment conditions.

Abstract

 ABSTRAK Tujuan penelitian ini adalah untuk memperoleh data dan informasi tentang besarnya pengaruh pembebasan jenis Acacia nilotica (L.)Willd.ex Del di Taman Nasional Baluran terhadap komposisi jenis tumbuhan penyusun savana dan kualitas dari savana yang ada. Metode yang digunakan adalah metode analisis vegetasi dengan  ukuran  petak  minimum  ditentukan  menggunakan  kurva  spesies  area.  Hasil  penelitian  ini menunjukkan bahwa komposisi jenis penyusun antara savana terbebas dari invasi dan savana terinvasi A. nilotica adalah berbeda. Komposisi jenis pada savana terbebas dari invasi terdiri dari 38 jenis terdiri dari jenis rumput, semak belukar, dan permudaan alam jenis pohon. Komposisi jenis penyusun savana yang terinvasi adalah 13 jenis terdiri dari 2 jenis rumput dan 11 jenis bukan rumput. Nilai indeks kesamaan komunitas adalah 38,38% sehingga kedua komunitas ini  berbeda. Indeks dominansi pada savana  yang terinvasi lebih tinggi daripada savana yang terehabilitasi, tetapi nilai indeks keragaman tertinggi pada savana yang terbebas dari invasi sebesar 1,216 sehingga pada komunitas ini lebih mantap dibandingkan dengan savana yang terinvasi jenis A. nilotica. Potensi biomassa pada areal savana terbebas dari invasi A. nilotica berkisar antara 1.067,5 kg/ha –  2.756,25 kg/ha lebih besar dari savana  yang terinvasi dengan potensi biomassanya antara 422,5 kg/ha– 1.000 kg/ha.

Abstract

Mangrove is a unique ecosystem that has complex biotic and abiotic components. Soil and water microorganisms have function as decomposer in mangrove forest ecosystem. This paper studies the soil and water microorganisms' diversity, their potential, function in ecosystem and their role as environmental parameters in mangrove area of Teluk Kelumpang, Selat Laut and Selat Sebuku Natural Reserve (Kelautku Natural Reserve). Data of soil and water microorganisms were recorded from soil and water samplings then analyzed in the laboratory. Results show that benthos in Selat Sebuku figure the highest diversity index. Anadara granosa is one of the common benthos found in Selat Sebuku. In contrary the phytoplankton in Selat Sebuku is the lowest value compared to the other two locations, due to the settlements in the locations and it was suspected that Selat Sebuku has a relatively larger wave exposure than the two other locations. In addition, input of organic matters from the settlements in Teluk Kelumpang and Selat Laut is also effected by the growth of phytoplankton. Cyanophyta found in Teluk Kelumpang and Selat Laut was genera of Oscillatoria that showed high tolerance genera to the environment conditions.

Abstract

Rehabilitation efforts were conducted in 2018 and 2020 to restore, maintain, and enhance forest and land functions following the 2015 fire on forest area with special purpose (KHDTK) Tumbang Nusa, Central Kalimantan. This study aims to determine the characteristics of stand structure, quantitative ecological values, aboveground biomass values, and preliminary projections of rehabilitation plant valuation in post-fire peat forest ecosystems. Study area was conducted in two rehabilitation blocks in 5 and 7 years old after rehabilitation. Vegetation analysis employed a nested sampling method, utilizing a plot size of 60 x 60 m, with Block I contain three plots (27 subplots) and Block II containing eight plots (72 subplots). Vegetation inventory and four carbon pool measurements were carried out on the understorey, seedlings, saplings, poles, and trees. The stand density value in Block I is 379 stems ha–1 with a basal area of 21.18 m2 ha–1 , while in Block II it is 503 stems ha–1 and 11.27 m2 ha–1 . The stands have good ecological value and stable vegetation, with a medium-scale species diversity level (H' = 1.53–2.80), a low-scale species dominance level (D = 0.10–0.42), commonly a high species richness value (R = 3.07–6.01), and medium to high species evenness values. The composition of rehabilitation plants are similar, but Block I has a higher proportional basal area of 3.72%. The projection of aboveground carbon biomass is 70.7 ton ha–1 and 77.7 ton ha–1 , respectively. As a preliminary study, the effectiveness of the rehabilitation valuation approach can be assessed by the productivity and quantitative ecology.
