Abstract

Peat is a wetland region in Indonesia with a very high water storage capacity. However, the amount of humic compounds obtained from the accumulation of organic substances in peat makes the water unable to be used for daily purposes. Peat water treatment with several methods has been carried out, such as coagulation, electrocoagulation, flocculation, and filtration. However, the result of clumping or filtering in such a way raises new environmental problems. One method which effective and efficient used in peat water treatment is photocatalytic. Several materials based-semiconductor was developed as a photocatalyst, another modification of photocatalyst is combining the adsorbent as a porous supporting photocatalyst which can improve its performance.

Abstract

This study aims to determined the level of flood vulnerability and most dominant factors that cause flood vulnerability in the Kahayan watershed, Gunung Mas District in Central Kalimantan. This study used a quantitative method by looking at the effect of each flood parameter to determine the level of flood vulnerability or vulnerable areas in the Kahayan watershed. The results are based on research carried out in the Kahayan watershed which has 4 levels of flood vulnerability classification: low vulnerability, medium vulnerability, high vulnerability, and very high vulnerability. The high level of flood vulnerability was the largest area with an area of ​​568.146 ha or 65,25% of the Kahayan watershed area of ​​Gunung Mas District as a whole, the medium vulnerability level was 185.634 ha (21,32%), very high vulnerability level was 61,716 ha (7,09 %), and low vulnerability was the area with the smallest area of ​​55.231 ha (6,34%) of the total area of ​​the Kahayan watershed in this district. The sub-districts with the highest area at a very high level of flood susceptibility were Tewah sub-district and Kurun sub-district. The most dominant factor that causes flood vulnerability in the Kahayan watershed area of Gunung Mas District was the slope that reaches 0-8% which was included in the flat category, with 3 land criteria, namely floodplain areas, river border areas, and basin areas.

Abstract

Dosis radiasi yang diberikan semakin besar kemungkinan terjadinya kerusakan jaringan sel. Untuk memastikan dosis radiasi tetap terjaga maka dilakukan uji kesesuaian untuk keselamatan radiasi, salah satu pengujian kesesuaian pesawat mobile X-Ray yaitu luas lapang kolimator dengan luas lapang berkas sinar-X. Sesuai Keputusan Menteri Kesehatan No. 1250/SK/XII/2009, bahwa gambaran pertengahan luas lapangan sinar-X harus berada diantara 2 % (maksimum) dari jarak fokus ke bidang film/ Focus Film Distance (FFD) terhadap pertengahan lapangan penyinaran berkas cahaya kolimator dalam perencanaan bayangan. Penelitian Pengujian kolimator dilakukan dengan menggunakan metode koin logam yang diletakkan di atas meja yang disediakan dengan penyinaran luas lapangan 15x15 dan 30x30 dengan FFD 100 cm. Penyinaran Ekspose dihasilkan citra yang dirancang untuk mengevaluasi luas lapang kolimator. Hasil pengujian luas lapang kolimator menunjukkan bahwa pada FFD 100 cm dengan luas lapangan 15x15 dan 30x30 diperoleh rata-rata sumbu X= 0.910 %, sumbu Y=0.910 % Nilai pergeseran yang terjadi masih dalam batas toleransi. Sebaiknya dilakukan pengujian secara berkala satu bulan sekali untuk menjamin mutu alat mobile X-Ray.

Abstract

The Natural Laboratory of Peat Swamp Forest Area known as the Center For International Co-operation in Management of Trofical Peatland (CIMTROP) University of Palangka Raya has been set as specific research area of tropical peat swamps since 1993 and has a 50.000 hectares total area. Natural Laboratory of Peat Swamp Forest Area – CIMTROP University of Palangka Raya is peat and sandy land and as a catchment water area, that is crucial to preserve and protect its ecosystem. This research used remote sensing and GIS technology for land cover monitoring utilize Sentinel-2 images. The purpose of this research was to determine (1) land cover changes in the Natural Laboratory/CIMTROP UPR in 2016 and 2021, (2) The rate of land cover change in the Natural Laboratory/CIMTROP UPR and (3) the causes of land cover change in the Natural Laboratory/CIMTROP UPR. Land cover analysis by interpreting Sentinel-2 images in 2016 and 2021 used Supervised Classification Technique. Based on results of the analysis, there were five land cover classes: forest, shurbs, brush, swamp grass and open land. The accuracy testing process performed uses a confusion matrix method to produce mapping accuracy values for each land cover class. Between 2016 to 2021, the change in forest class decreased from 31.809,40 hectares (67,37%) to 29.888,10 hectares (63,30%). Contrary to the shrub class, there was and increase of 1.762,30 hectares (3,73%) to 2.585,20 hectares (5,47%). The increase in shrub area was due to forest reforestation, degradation and deforestation from the forest and land fires which occurred in previors years.

Abstract

Cyanobacteria were formerly known as blue-green algae and are currently considered algae-like Gram-negative bacteria belonging to the bacterial kingdom. Lack of scientific information on the presence and distribution of cyanobacteria species in peat water habitats, particularly in Central Kalimantan, Indonesia, which has extensive peat waters. This study aims to conduct a preliminary exploration as an initial action for further research on the diversity and distribution of cyanobacteria species in peat water ecosystems. The results of the study reported that 5 species of cyanobacteria were found to be present in the peat water habitat in Palangka Raya, Central Kalimantan, Indonesia, belonging to the orders Chroococcales, Oscillatoriales, and Synechococcales. The cyanobacteria species found in this study include Microcystis sp., Chroococcus sp., Oscillatoria sp., Arthrospira sp., and Pseudanabaena sp. These findings indicate that further research needs to be carried out to explore, identify and isolate cyanobacteria from peat waters to obtain more detailed and clear data as a basis for optimizing the potential and benefits of cyanobacteria for sustainable life.

Abstract

Electrospun nanofiber is a nano-sized fiber that is formed using an electrospinning machine. The important parameters affecting the formation of electrospun nanofiber are: (1) the coating material, (2) process conditions (electrical, flow rate, and the distance between the syringe and the collector), and (3) environmental conditions (temperature and humidity). The experiment results showed that electrospinning optimum conditions are achieved at a flow rate of 5 ml/l, the electrical voltage of 6 kV, the distance between spinneret with the collector ranged from 8 to 10 cm, the ambient temperature of 25°C, and relative air humidity (RH) of 50%. Best concentration of PVA is 10-15%.

Abstract

Indonesia has the largest distribution of peatlands worldwide and is spread over Sumatra, Kalimantan, and Papua islands. Peatland is one of the land resources with a hydrological function and can store water in the form of peatwater. Peatwater is brownish-red due to high dissolved organic matter, especially in the form of humic acid and its derivatives, high organic matter content, low pH, and low cation content. Peatwater is classified as polluted water, unsuitable for consumption, and cannot be used directly as drinking, bathing, or washing water. The Mixed Matrix Membrane Fabrication method is expected to be used for peatwater purification by adding silica filler from rice husk ash. Rice husk has a high silica filler content of >90%. The higher the silica level, the better the material absorbs harmful chemical compounds in peatwater, one of which is humic acid.
