Abstract

One of the essential nutrients for plant growth is phosphate, but just 0.1-0.5% is available for plants to use. This problem can be solved by using chemical fertilizers, but for long run could damages environment. An alternative way for chemical fertilizers is using phosphate solubilizing fungi. Phosphate-solubilizing fungi can be isolated from soil or litter. This study aims to isolated fungi from litter’s forest of Aka Barayun, Lembah Harau, West Sumatra and determine it’s phosphate solubilizing potency. Medium for isolation was Potato Dextrose Agar (PDA) and medium for phosphate solubilizing activity test was solid Pikovskaya medium with source of bound phosphate Ca3(PO4)2. Thirteen fungi were isolated successfully from litter’s forest of Aka Barayun, Lembah Harau, West Sumatra, which are coded SR1-SR13. Based on macroscopic and microscopic morphology, it is known that two isolates belong to the genus Penicillium, two isolates belong to Trichoderma, one isolate of Verticillium, one isolate of Fusarium, two isolates of yeast and two isolates are not yet known. Results of the phosphate solubilizing test showed that only seven isolates were able to solubilize phosphate, they are isolates SR2, SR5, SR6, SR7, SR11, SR 12 and SR 13. Phosphate solubilization index is low and ranges from 0.1 to 0.4.

Abstract

Thermophilic bacteria are bacteria that are able to survive in high temperatures ranging from 45 – 80oC so that they have the potential to produce enzymes that are stable against heat. Thermophilic bacteria can be found in various places in nature that have potential hot springs. One of the potentials of thermophilic bacteria in producing enzymes is the xylanase enzyme. Xylanase is able to hydrolyze xylan (hemicellulose) into xylo-olisaccharides and xylose. In the industrial world, xylanase enzymes are used as paper whiteners, increase the volume of bread, as juice purification, and are used in the manufacture of detergents. This research is a type of descriptive research that aims to determine the specific activity of the xylanase enzyme and the levels of xylanase protein produced by thermophilic bacteria SSA (Sapan Sungai Aro) with bacterial isolates SSA3, SSA4, SSA5, SSA6, SSA7, SSA8, SSA13, SSA14 and SSA15. The results showed that the bacterial isolates SSA3, SSA4, SSA5; isolates SSA6, SSA7, and SSA8; and SSA13, SSA14 and SSA15 respectively had specific activity of the xylanase enzyme with an average value of 0.1614 Unit/mg; 0.1638 Unit/mg and 0.1473 Unit/mg. The final measurement results showed that the highest specific activity of the xylanase enzyme was in the consortium of thermophilic bacteria isolates SSA6, SSA7, and SSA8 with an average of 0.1638 Unit/mg.

Abstract

Rice has become food for most of the world's population. Indonesia is the third largest producer in the world. However, in fact rice production in Indonesia has decreased by 0.43% compared to 2020. One of the factors that can cause this decline is drought. Because rice is a semi-aquatic plant that grows normally in flooded conditions, it makes drought stress very threatening. Drought stress that occurs in plants causes plants to experience oxidative stress due to excessive accumulation of ROS. PEG is a compound that is widely used to provide drought conditions in plants. Previous research has classified several varieties of rice plants based on their level of resistance to drought. However, it is not yet known how the morphological response will be in different periods of drought stress and rewatering treatment. This research was conducted by giving treatment in the form of control (Yoshida nutrient culture solution) and drought stress (Yoshida + PEG-6000 20% solution) repeated 3 times. The observed parameters were RWC which were analyzed using standard errors and morphological images of roots and leaves. The results showed that the RWC obtained during the stress period from the third to the fifth day, Harum had the highest value according to its class as tolerant rice. After rewatering Rosna has a better recovery ability. In addition, root morphology shows differences in the form of root length, small root diameter, inhibition of adventive root growth. On the leaves include a decrease in leaf area, leaf curl up, and leaf yellowing.

Abstract

Tuberculosis (TB) is a global issue that is a priority in both Indonesia and Malaysia. Since being designated by WHO at 1993 as a global public health threat, Tuberculosis (TB) has become one of the top 10 leading causes of death worldwide. Recently, the number of Tuberculosis (TB) patients in Indonesia has increased, especially paediatric TB cases. In addition, Tuberculosis (TB) cases also increased in Malaysia. For the West Sumatra region, the highest number of TB patients is in Padang City. Since Tuberculosis (TB) is a disease that can affect anyone including children, the school environment as one of the places where children gather and interact has the opportunity to be a place for the spread of TB cases as well as having an important role in preventing TB transmission. However, in reality, the role of schools in early prevention efforts related to Tuberculosis (TB) disease in children, especially elementary school students, is still not optimal. In line with this, Tuberculosis (TB) disease is closely related to the human respiratory system which is one of the topics discussed in the human anatomy and physiology course in the MBKM activity between the Department of Biology FMIPA UNP and the Department of Biology UPSI. Therefore, it is necessary to make preventive efforts in the form of Tuberculosis prevention education. The results of community service are that several stages of community service activities have been carried out regarding Tuberculosis (TB) prevention education for elementary school students, namely the students involved are enthusiastic about the activities held, then pre-service biology teacher are also actively engaged in preparing and carrying out this activity and students' knowledge related to general knowledge, symptoms, their relationship with the respiratory system and prevention efforts are classified as good.

Abstract

Indonesia has local varieties of citrus that are no less than imported citrus, especially in terms of fruit freshness. However, people are more interested in the color of citrus peel so people prefer imported citrus to local citrus, especially in Sumatera. Therefore, it is necessary to carry out efforts to conserve and improve the characteristics of these citrus to improve their quality through plant breeding. This study aims to optimize DNA isolation methods for citrus fruit samples with Chelex-TE and to determine the genetic profile of local Sumatera citrus and imported citrus using the genotyping RAPD. The samples used were several local citrus in Sumatera (Citrus Siam Mountain Omeh, Citrus Madu, Citrus Keprok Maga, Citrus Keprok Brastepu and Citrus Pasaman) and imported Citrus (Citrus Sunkist, Citrus Clemengold, Citrus Murkot and Citrus Wokam). DNA was isolated using the 10% Chelex-TE method which was optimized for several parameters such as grain size, fruit skin and leaves. RAPD was performed using 10 RAPD primers. The results showed that the optimum 10% Chelex Chelex-TE isolation method was a sample size of 1 grain. The amplification of local Sumatran citrus and imported citrus using 10 single primers produced polymorphic bands. The value of jaccard's similarity indicates that the five samples of Sumatera local variety of citrus and imported citrus have high genetic variation.

Abstract

Tempe is a typical Indonesian food that comes from fermenting soybeans with the fungus Rhizopus sp. Tempe is known to have good nutritional value because of the content contained in soybeans themselves and other microorganisms that appear as a result of the tempe fermentation process. The fermentation process increases the activity of bacteria in tempe which are beneficial for digestion, one of which is lactic acid bacteria. This research aims to see the differences morphological forms  and genomic of lactic acid bacteria produced by tempe wrapped in banana leaves and tempe wrapped in plastic. The differences in fermentation that occurred in tempe wrapped in banana leaves and those wrapped in plastic resulted in differences in lactic acid bacteria type. Based on the isolation of bacteria on Mann de Rogosa Sharpe Agar medium, 15 isolates of lactic acid bacteria were produced, with general morphological forms of bacilli and coccus. Then, genomic identification was carried out using the PCR. The phylogenetic tree built based on the 16S rRNA gene sequence can show the relationship between LAB diversity at the species level, but cannot differentiate LAB from the strain level.

Abstract

Cassava is one of the most important food commodities besides rice and corn. Carvita 25 is a somaclonal variation that was induced from Adira IV cassava variety. Our study aimed to analyze the genetic differences of Carvita 25 compared to Adira IV by using SSR markers. Two cassava varieties, Carvita 25 and Adira IV, were used as plant materials and eleven SSRY primers were used to amplifythe fragments of cassava DNA. The results showed that SSRY 151 primer produced the highest polymorphic band (85.71%) where 6 out of 7 alels were polymoprphics with the length size from 120 to 600 bp. Of the total 56 of polymorphic bands, 26 alels were previously present in Adira IV but then it can not be found in Carvita 25, while 30 other bands were new fragments that were previously not present in Adira IV but then were present in Carvita 25. These genetic differencesof both Adira IV and Carvita 25 were also strengthened by the Jacard similarity value. The Jaccard similarity between Carvita 25 and Adira IV were 0.40-0.50, while the similarity between plants of Carvita 25 were 0.79-0.87, and in plants of Adira IV were 0.98- 1.These values showed thewide genetic difference between Adira IV and a somaclonal variation of Carvita 25.Keywords: cassava, Carvita 25, polymorphic, somaclonal variation, SSR Marker.

Abstract

Catalase (CAT) is an antioxidant enzyme that plays an important role in plant growht and defense against abiotic stress, one of which is rice (Oryza sativa). When plants are under abiotic stress conditions, the CAT gene will be regulated and expressed as a form of defense response to stress. To determine the expression of this CAT gene, optimal primers and annealing temperatures are needed to spesifically amplify the CAT gene. This study aims to design primers and determine the optimal annealing temperatures to amplify the CAT gene. Primers are designed using the tools pick primer, primer BLAST and geneious prime. Primers are designed in silico and must meet the ideal primer criteria because they will be used in vitro. Optimization of the annealing temperature was carried out using a PCR temperature gradient. The results of this study obtained a pair of primers, namely forward primer 5’-ATAAGTAGGGCGGTGTGTGG-3’ with a primer length of 20 bp, and reverse primer 5’-GCGAGTTGTTGTTGTTCCATAC-3’ with a primer length 22 bp. This primer pair produces a 185 bp amplicon in the Oryza sativa CAT gene. The optimum annealing temperature for this primer pair is 60ºC.
