Abstract

The development of electronic learning materials is very necessary for the midst of the COVID-19 pandemic which requires lecture activities to be carried out online. This was carried out to support physical distancing to break the chain of transmission of COVID-19. Currently, there are not many electronic learning materials available that lead to student-centered learning (SCL) and can be implemented amid the COVID- 19 pandemics. The purpose of this research is to develop an eLEMA (Electronic Learning Material) application, an Android-based electronic learning material with content or material that can be accessed online and offline, and with features that make it easier for users to operate. This research is a research development (Research and Development; R & D) to develop Android-based ELEMA-SCL Protozoa (Electronic Learning Material-Student Centered Learning) for Zoology courses. This development model consists of 3 phases of approach, namely: (1) Phase 1: Needs Assessment; (2) Phase 2: Design; and (3) Phase 3: Develop / Implement. The product developed in the form of an Android-based eLEMA application made using the MIT App Inventor is feasible to implement. The implementation results show: (1) the effectiveness of online and offline lectures with a gain value of 0.52 in the Medium category; (2) student response to the implementation of eLEMA is positive. Thus, the eLEMA application can be used for online and offline lectures during the COVID-19 pandemic.

Abstract

The resistance and survival ability of phytoremediator plants in a polluted environment is thought to be a form of genetic adaptation. This research aimed: (1) to identify the dominant plant species in ex-gold mining area; (2) to analyze the genetic profile of phytoremediator plants from ex-gold mining area; and (3) to compare the genetic profile of heavy metal phytoremediator plants from ex-gold mining area with the same plant species from non-mining area. The samples of this study were Cyperus sp., Lycopodium sp., and Melastoma sp. The research procedures carried out include sample collection, DNA isolation, DNA amplification with PCR, and DNA visualization with Electrophoresis. The results show that the dominant plant species of ex-gold mining area are Cyperus sp., Lycopodium sp., and Melastoma sp. The genetic profile analysis of dominant plant species of ex-gold mining area show that no DNA bands appeared from the target gene as the result of amplification using specific primers of Metallothionein gene. The result of RAPD analysis using OPA-04 universal primers show that at 500-750 bp there are differences in DNA bands that appeared between the samples. DNA bands that appeared in the genetic profile of phytoremediator plants is thought to be the representation of the gene that responsible for heavy metals tolerance.

Abstract

Kawasan hutan maupun sungai-sungai di Kalimantan Tengah, telah terdampak akibat kegiatan penambangan emas skala kecil (ilegal) selama puluhan tahun. Para penambang menggunakan merkuri sebagai bahan kimia utama dalam prosesekstraksi emas, dan setiap tahun melepaskan tidak kurang dari 1.000ton bahan berbahaya ini ke lingkungan, baik udara maupun air. Pencemaran merkuri di lingkungan perairan, dapat dikurangi atau dihilangkan dengan menggunakan sekelompok mikroorganisme yang mampu untuk mereduksi merkuri yang disebut dengan bioremediasi. Metode bioremediasi lebih ekonomis, karena mikroorganisme memiliki kemampuan untuk mendegradasi kontaminan ke dalam bentuk yang tidak berbahaya. Bakteri dan alga yang hidup di perairan sekitar tambang emas diduga memiliki kemampuan resistensi terhadap kontaminan logam berat merkuri. Sampel bakteri dan alga yang diambil dari sekitar tambang diseleksi dengan perlakuan merkuri (Hg) untuk mengetahui potensinya sebagai bioremediator logam berat. Penelitian ini bertujuan untuk Eksplorasi dan Optimasi Mikroorganisme Potensial untuk Bioremediasi Merkuri dari Areal Tambang Emas di Sungai Kahayan. Pengambilan sampel dilakukan di 5 titik yang teridiri 3 titik di areal tambang (T1, T2, T3), 1 titik di hulu tambang (HU), dan 1 titik di hilir tambang (HI). Hasil penelitian menunjukkan: (1) mikroalga potensial bioremediasi merkuri dari areal tambang emas sungai Kahayan termasuk ke dalam genus Chlorella dan mampu bertahan dengan perlakuan konsentrasi Hg sampai 7 ppm; dan (2) bakteri potensial bioremediasi merkuri dari areal tambang emas sungai Kahayan mampu bertahan dengan perlakuan konsentrasi Hg sampai 13 ppm yang terdiri dari 3 isolat, yakni I1 (bakteri dari sampel air), I2 (bakteri dari sampel air), dan I3 (bakteri dari sampel sedimen). Ketiga isolat bakteri potensial termasuk ke dalam kelompok bakteri Gram Negatif. Isolat 1 dan isolat 3 merupakan spesies Pseudomonas sp. berdasarkan kemampuannya menghasilkan pigmen berwarna kuning pada media cair.ABSTRACTForest areas and rivers in Central Kalimantan have been affected by small-scale (illegal) gold mining activities for decades. Miners use mercury as the main chemical in the gold extraction process, and annually release no less than 1,000 tons of this hazardous material into the environment, both air and water. Mercury pollution in aquatic environments can be reduced or eliminated by using a group of microorganisms capable of reducing mercury known as bioremediation. The bioremediation method is more economical, because microorganisms have the ability to degrade contaminants into harmless forms. Bacteria and algae that live in the waters around the gold mine are thought to have the ability to resist mercury heavy metal contaminants. Bacteria and algae samples taken from around the mine were selected with mercury (Hg) treatment to determine their potential as a heavy metal bioremediator. This research aims to explore and optimize potential microorganisms for bioremediation of mercury from the gold mine area in the Kahayan River. Sampling was carried out at 5 points consisting of 3 points in the mine area (T1, T2, T3), 1 point upstream of the mine (HU), and 1 point downstream of the mine (HI). The results showed: (1) the potential microalgae bioremediation of mercury from the gold mining area of the Kahayan River was included in the Chlorella genus and was able to survive the treatment of Hg concentrations up to 7 ppm; and (2) potential mercury bioremediation bacteria from the gold mining area of the Kahayan River were able to survive with a treatment of up to 13 ppm Hg concentrations consisting of 3 isolates, namely I1 (bacteria from water samples), I2 (bacteria from water samples), and I3 (bacteria from sediment samples). The three potential bacterial isolates belong to the Gram negative bacteria group. Isolate 1 and isolate 3 are Pseudomonas sp. species based on their ability to produce yellow pigment in liquid media.

Abstract

Coelastrum Nägeli 1849 is a genus of microalgae belonging to the scenedesmaceae family and currently has 31 taxonomically accepted species. Coelastrum can be found in the freshwater environment, e.g., in ditches, ponds, lakes, and swamps forming small colonies called coenobia. As no data records the description of this genus from the peat water environment, it is necessary to conduct a morphological study, especially the Coelastrum cambricum species which is commonly found in peat waters. Water samples were collected from peat waters in a ditch at the Bukit Keminting Road (Palangka Raya) near the Fisheries Department, University of Palangka Raya. Morphological examination of Coelastrum cambricum was carried out microscopically directly on the collected water samples and then photographed for further identification. Coelastrum cambricum was identified from the water samples collected from peat water at the sampling site. The peat water has a brownish color and looks fairly clear like brewed tea that allows enough sunlight to penetrate it. C. cambricum forming a spherical coenobium consisting of 4-32 cells and appear green in color and it is observed that coenobium groups form larger colonies consisting of 4 to 24 coenobia. The diameter of coenobia ranges from 40-62?m. In this study also observed the distinctive morphological characteristics of C. cambricum where 6 cells were observed in the center of the coenobium forming a pentagonal pattern that looked the same in all specimens observed. This characteristic has the potential to be studied further as a key feature of Coelastrum species identification.
