Abstract

Kelompok peduli pesisir memiliki peranan penting dalam rehabilitasi dan perlindungan hutan mangrove, khususnya berkaitan dengan upaya menumbuhkan aspek kelembagaannya. Studi ini bertujuan menganalisis kinerja kelembagaan, peran stakeholders, dan hak pemilikan hutan yang mungkin diwujudkan setelah rehabilitasi mangrove dianggap berhasil, serta untuk mendeskripsikan beberapa dimensi pentingnya sebagai model pengelolaan hutan mangrove. Penelitian dilakukan pada bulan September 2021 hingga Agustus 2022 di Kelurahan Setapuk Besar- Kota Singkawang, Kalimantan Barat, melalui suatu metode campuran: kuantitatif-kualitatif. Data kuantitatif dikumpulkan dari 78 responden warga komunitas pesisir dengan cara wawancara terstruktur, sedangkan data kualitatif diperoleh melalui wawancara mendalam terhadap informan kunci. Analisis data kuantitatif mengenai kinerja kelembagaan diukur dari proporsi warga yang mengetahui terhadap aturan utama perlindungan hutan mangrove, sedangkan secara kualitatif dilihat dari partisipasi anggota kelompok dalam rutinitas kegiatan rehabilitasi dan konservasinya. Hasil penelitian menunjukkan bahwa sistem kelembagaan telah berfungsi dengan baik, buktinya sekitar 90 persen warga pesisir mengetahui aturan perlindungan hutan mangrove di komunitasnya. Selain itu partisipasi anggota kelompok dalam aksi rehabilitasi atau konservasi melalui inisiatif kelompok merupakan faktor kunci keberhasilan. Dimensi penting dalam menjaga keberlanjutan konservasi mangrove di sekitar kota pesisir adalah melalui pemeliharaan kelembagaan lokal dan penumbuhan ekowisata. Tittle: Analysis of the Success of Mangrove Forest Management: A Case Study on Rehabilitation and Conservation by the Coastal Care CommunityCoastal care groups have an essential role in rehabilitating and protecting mangrove forests, particularly concerning efforts to grow their institutional aspects. This study aims to analyse the institutional performance, stakeholder roles, and forest property rights that may be  realized after the success of mangrove rehabilitations, and to describe some of its essential dimensions as a model for mangrove forest management. This study was conducted in September 2021 until August 2022 in Setapuk Besar-Singkawang city, West Kalimantan, through a mixed methods: quantitative-qualitative. Quantitative data were collected from 78 respondents of the coastal communities using structured interviews, while qualitative data was gotten through in-depth interviews with the key informants. Quantitative data analysis, concerning the institutional performance is measured by the proportion of residents who know the main rules for protecting mangrove forests, while qualitatively it is seen from the participation of group members’ in their routine rehabilitation and conservation activities. The results showed that the institutional system has functioned well, as evidenced is around 90 percent of the coasta residents knowing precisely the rules for protecting the mangrove forest in their community. Besides, the group members’ participation in rehabilitation or conservation actions through group initiatives is the key to success. An important dimension in maintaining the sustainability of mangrove conservation around coastal cities is through the maintenance of local institutions and the growth of ecotourism.

Abstract

This research aims to compare the methods of bulk density measurements in peat soils. The methods are ring sample, peat auger, and syringe. The research was conducted in peat soils in Pontianak City. The research was carried out from June to December 2023. Peat samples were the surface peat (0-10 cm). The samples were collected from five plots, and five replications. On average, the value of bulk density measured by the ring sample was 0.27 g cm-3, which is significantly different from bulk density values measured by the peat auger and syringe: 0.11 g cm-3 and 0.09 g cm-3, respectively. Bulk densities of peat auger and syringe are statistically indifferent. Soil compaction during sampling causes the ring sample's high bulk density value. Accordingly, carbon stock calculation based on ring sample bulk density is significantly higher than carbon stocks calculated by bulk densities of auger and syringe. The bulk density measurement with a peat auger took longer because a water displacement approach must measure the sample volume. Collecting bulk-density samples with a syringe is the easiest and fastest. The volume of the syringe sample is only 10 cm3, and the sample can be taken until the mineral substratum. The number of sample collected by syringe can be significantly increased at 5 cm sampling interval, or equals to 10 sub-samples per 50 cm peat core. Pearson linear correlations of these three methods are sufficiently strong.

Abstract

Channel bar has drawns public attention because the ownership of this channel bar is not yet defined. This research investigated the fluctuation of channel bar sizes between 1972 and 2022,, and addressed the potential of channel bar as a land bank. The research was conducted in Mempawah District, West Kalimantan Province. Landsat spatial data and aerial photographs of drone were used. A number of interviews were done to understand the potential of this channel bar as a land bank. Spatially and temporally, the channel bar in Mempawah District is fluctuated, with the current area of 646 ha. The dominant land cover of this channel bar is mangrove, which plays an important role in coastal abrasion prevention. Therefore, the use of channel bar as a land bank is potentially to protect mangrove, with fully participation of local communities. One of potential uses is to develop ecotourism, and designated a channel bar land bank for mangrove protection in the District spatial planning.

Abstract

Peat soils are formed from woody materials which generally contain a lot of lignocellulosic organic  compounds such as lignin which in the degradation process produces reactive carboxyl groups and  phenolic  compounds.  Degradation  of  phenolic  compounds  can  be  carried  out  enzymatically  by  phenol-  degrading bacteria. The purpose  of this study was to compare the number  of  bacterial colonies  degrading phenolic compounds in the acrotelic and catotelm layers in the upstream and downstream  locations of the peat swamp forest in Permata Village, Terentang District, Kubu Raya Regency. Soil  samples were taken in 2 plots (upstream and downstream from the canal blocking) at a distance of 500  meters using a peat drill. Each plot was then taken 3 drill points to form a triangular pattern with a  distance of 30 meters with a peat depth level (Acrotelm) 0-10 cm, 10-20 cm and peat depth (Catotelm)  300-310 cm, 310-320 cm. Bacterial colonies were counted using the Total Plate Count method on  Mineral Salt Medium and pure phenol selective media. Total phenolic compounds in peatlands were  tested using 10% Folin-Ciocalteu solution and 2% Na2CO3. The number of bacterial colonies at  locations  upstream  from  the  canal  blocking  in  the  acrotelmic  layer  is  0-10  cm  deep  (7,5x104  cfu/gr)  and  10-20 cm deep (8,8x104  cfu/g), while bacteria in the catotelm layer are 300-310 cm deep (2,1x104  cfu/gr)  and  a  depth  of  310-320  cm  (2,2x104  cfu/gr).  The  number  of  bacterial  colonies  downstream  from  the canal blocking in the acrotelm layer at a depth of 0-10 cm (2,3x104  cfu/gr) and at a depth of 10-20  cm (3,1x104  cfu/gr), while bacteria in the catotelm layer at a depth of 300-310 (1,7x104  cfu/g) and a  depth  of  310-320 cm  (1,6x104  cfu/g).

Abstract

The groundwater table (GWT) is widely recognized as a key factor influencing CO2 emissions in tropical peatlands. However, previous studies investigating this relationship have reported diverse results. This variability likely stems from the dynamic nature of field-based groundwater conditions. To address this, our study investigated the relationship between controlled GWT and CO2 emissions in a laboratory experiment using PVC columns filled with peat soil. GWT depths were adjusted to 20 cm, 30 cm, 40 cm, 50 cm, and 60 cm within a large container filled with peat pore water. CO2 emissions were measured using an Infra Red Gas Analyzer - Environmental Gas Monitoring-4 instrument, with a closed-chamber system. Our findings revealed significant differences in CO2 emissions between treatments, except for the transition from 20 cm to 30 cm GWT. Correlation analysis showed a positive correlation (R² = 0.25). Notably, CO2 emission factor values based on average yearly emission rates displayed a substantial increase with decreasing GWT, exhibiting a strong exponential relationship (R² = 0.99).

Abstract

Phenols play an important role in inhibiting the decomposition rate of peats. This research compares the total phenols, tannins, and colonies of phenol-degrading bacteria in natural and cultivated peatlands. The work was conducted from September to December 2023 on the peatlands in Pontianak, West Kalimantan. Samples of 60 cm3 were collected from the peat surface. The samples were taken from 4 types of peats, namely natural peats covered by ferns (A), cultivated peat with raised beds (B), cultivated peat with raised beds ameliorated with lime and beef manure (C), and cultivated peat with raised beds ameliorated with lime, beef manure, and Jadam fertilizer (D). The total phenols content was measured using the Folin-Ciocalteu 10% method using a UV-Vis spectrophotometer at a wavelength of 765 nm. The total tannins content was measured using the Folin-Denis method using a UV-Vis spectrophotometer at a wavelength of 740 nm. Total bacterial colonies were counted using the Total Plate Count method on selective Mineral Salt Medium (MSM) agar with the addition of phenol solution. The results showed that the average total phenols and tannins content values were generally low in the cultivated peats, particularly in the raised bed (B). The results indicate that the cultivated peat accelerates the activity of phenol-degrading bacteria. Keywords: Jadam fertilizer, phenols, phenol-degrading bacteria, peats, tannin

Abstract

The carbon storage in mangrove forest plays a crucial role in climate change mitigation. Sungai kupah village is an ecotourism village engaged in mangrove forest tourism restoration. Therefore, the government"™s program to preserve mangrove forst aligns with the conservation efforts undertaken by tourism enthusiasts. Hence, a study is needed on carbon stock reserves at several locations in the Sungai kupah mangrove forest. This research utilized non-destructive sampling method and applied available allometric equations. Data collection involved measuring the diameter of breast height of trees within 10 x 10 meter sample plots with a 5 meter plot interval. The research results indicated an average carbon stock production in above ground biomass of 167.05 tons/ha along the entire path. The highest carbon content was found in path three at 96.46 tons/ha, followed by path two at 72.29 tons/ha, and the smallest in path one at 12.94 tons/ha. Based on the growth rate, the highest stored carbon value for trees is found on line 3, with a value of 83.21 tons/ha, while for seedlings on line 3, it is 13.25 tons/ha. The dominant vegetation species in each zone are Sonneratia caseolaris in line I, and Avicennia lanata in both line II and line III. Therefore, the vegetation density in each zone is related to the biomass value obtained and the carbon stock. Keywords: allometric, biomass, carbon, mangroves, mitigation.

Abstract

Provinsi Kalimantan Barat memiliki lahan gambut seluas 1,55 juta ha. Lahan gambut merupakan lahan marjinal yang digunakan untuk budidaya pertanian. Tingkat kesuburan lahan gambut rendah dengan kandungan senyawa organik seperti lignin, selulosa, hemiselulosa, dan tanin. Penelitian ini bertujuan untuk membandingkan konsentrasi senyawa tanin pada lahan gambut yang digunakan untuk budidaya pertanian hortikultura dan semak belukar. Penelitian dilaksanakan dari bulan Mei sampai Juli 2024. Sampel diambil dari 3 plot masing-masing lahan dengan jumlah 4 titik pengambilan. Pengukuran kandungan total tanin dilakukan menggunakan metode Folin-Denis dengan Spektrofotometer Uv-Vis pada panjang gelombang 740 nm. Hasil uji T taraf 5% menunjukkan bahwa konsentrasi senyawa tanin pada lahan budidaya dan lahan semak belukar berbeda tidak nyata. Hal ini diperkirakan karena kedua lahan sama-sama terindikasi telah terdekomposisi. Kesimpulan sementara penelitian bahwa konsentrasi senyawa tanin pada lahan budidaya sayuran dan semak belukar tidak berbeda signifikan.

Abstract

Peat forests are sub-optimal lands for agricultur, but most of them have been converted to agricultural uses. This study aimed to map changes in peatland use in Kedamin Darat Village, Kapuas Hulu District, West Kalimantan Province, and to examined the properties of peat in different land uses, namely forest, shrubs, and oil palm.. The study was conducted using Landsat 8 imagery from 2013, 2017 and 2021 to map land use changesin this village. Peat properties measured were bulk density, porosity, soil moisture, ash content and total organic carbon. The area of peat forest in 2013 was 2 488 ha, and decreased to 2 271 ha in 2021. The increase in area between 2013 and 2021 was shrubs, settlements and oil palm plantations. Bulk density and porosity in secondary peat  forest did not differ significantly from shrubs but differed significantly from oil palm plantations. Moisture content in oil palm plantations and shrubs was not significantly different from secondary peat forests but moistures in oil palm plantations soils were significantly different from shrubs. C-organic content was very high, and were idifferent in the three land uses. The utilization of peatlands by the community causes a change in the area of each land use from year to year followed by a decrease in peat function. Keywords: peat criteria, land kedamin, mapping, land use, peat soil properties INTISARIHutan gambut termasuk lahan sub-optimal untuk budidaya pertanian, namun sebagian besar telah dialih fungsikan menjadi beberapa penggunaan lain.
