Introduction: It is known that palm oil mills produce decanter solid as a byproduct in the form of organic solid waste. To test the opportunity to use decanter solid as a growing medium for oil palm seedlings, a study was conducted to evaluate, nutrient content, pH, and aggregate stability in media with different ratios of soil and decanter solid. Method: The design used in this study was a completely randomized design (CRD) consisting of 6 levels of treatment, namely A1 (1000 g soil + 0 g decanter solid), A2 (900 g soil + 100 g decanter solid), A3 (800 g soil + 200 g decanter solid), A4 (700 g soil + 300 g decanter solid), A5 (600 g soil + 400 g decanter solid), and A6 (500 g soil + 500 g decanter solid), and each the experimental unit was repeated 4 times. Result: The results showed that the addition of a decanter solid to Ultisol soil affected the pH value, macro and micro nutrient content and also improved soil aggregation. Conclusion: The best composition in increasing pH value, improving soil aggregation and increasing nutrient content is by mixing 40% decanter solid and 60% soil with an incubation time of 45 days.

Pangasius catfish rearing ponds and swamp waters are types of stagnant waters (lentic) that are commonly found in the South Sumatra region. Cyanobacter is a group of phytoplankton that plays an important role in the management of aquatic area, but it is not widely known which species is the most dominant in swamp waters. This study aims to determine the types of cyanobacter that are abundant in the swamps and Pangasius catfish cultivation ponds in Ogan Olir, South Sumatra. This research has been carried out by cyanobacter isolation from the swamp water and the pond, isolate liquid cultivation, DNA isolation, 16S rRNA gene amplification and DNA amplicon sequencing. The sequencing results were analyzed using BLAST (Basic local alignment search tool-nucleotide) and MEGA 6 with the help of NCBI gene bank data to obtain a phylogenetic tree for predicting the identity of the cyanobacter isolates. Based on the morphological characters, it is suspected that the pond isolates are similar to Synechoccocus and swamp isolates similar to Microcystis genera. The amplification of cyanobacter DNA using the PCR method with the universal 16S rRNA 63F (Forward) and 1387 R (Reverse) resulted 1302-1307 base pairs. Analysis using BLAST showed that the cyanobacter isolates from ponds have 91% similar to Uncultured Synechoccocus sp. from Australia, while the swamp isolates have 86% similar to Microcystis sp. from China. Key words : Cyanobacteria, Microcystis, PCR, Phylogenetic, Synechococcus

Batik is a world heritage from Indonesia which is a characteristic of Indonesian culture. On October 2, 2009 batik has been awarded as a cultural heritage from UNESCO. Indonesia has 5.849 batik patterns from Aceh to Papua. The ability to recognize batik cloth patterns is certainly quite difficult and only owned by certain people who have expertise. One way to identify batik patterns is by using a pattern recognition classification method based on quantitative measurements of the main features or characteristics of an object. Deep Learning is one solution to detect batik patterns automatically. One of deep learning methods that can classify patterns of batik patterns is Convolutional Neural Network (CNN). CNN is able to group and detect objects in the image automatically by accepting input data with a size of m×n. CNN uses image input through a convolution layer and be processed according to the specified filter. Each layer produces a pattern from several parts of the image that facilitates the classification process. This study uses the CNN method and obtains the average value of 96% accuracy, 96,78% precision, 96,74% recall, and 96,74%.

In this era of technology and information proliferating, programming skills are needed. Technology affects every area of life from industry, business, communication, transportation, health, and others. Everyone has the same opportunity to learn and master technology thus programming language courses are needed to provide education, innovation, and improvement of skills and abilities in the field of programming and data science to the public. Until now, programming language courses still use the conventional system, where everything is done manually, from class registration, class scheduling, teaching and learning process, and payment processing which results in many archives that must be stored for administrative purposes and require a relatively large amount of time for customers to come to the course location. Therefore, an information technology-based system is needed to fix the weaknesses of the old system. In this study, an Android-based programming language course application is designed to facilitate customers and course owners in teaching and learning activities and transactions. The design in this study uses the waterfall method, which consists of five stages, needs analysis, design, code, testing, and maintenance. The results obtained from testing applications using questionnaires on programming language course applications are 80% stated by course customers, where the application is easy to use, faster, and more practical in registering. In conclusion, this designed application can make it easier for customers to carry out teaching and learning activities and transact quickly and practically.

Lotus is a wild plant in wetlands that have not been widely used but has great potential to be developed as compost tea. Therefore, this research aims to evaluate the content of compost tea made from wild lotus found in wetlands, which has not been sufficiently used but has great potential to be developed as compost tea. It was conducted by testing several methods and compositions of compost immersion, namely A1, A2, A3, and A4 at Aeration 1:5, Aeration 1:10, Non-aeration 1:5, and Non-aeration 1:10, respectively. The results show that the pH value increased until day 8 of immersion and then decreased on days 9 and 10, with a range of 8.0-8.44, in the recommended range. Furthermore, the total dissolved solids in the 1:5 water ratio were lower than the 1:10 of compost and water. The content of nutrients (C-organic, N-total, and P-available), bacteria population, actinomycetes, fungi, and humic acid concentration were higher in aeration treatments for both 1:5 and 1:10 compost and water ratios. In addition, humic acid functional groups in compost tea for all treatments were detected, including OH-phenolic, C=C, C=C, COOH, CH3, secondary amides, and tertiary amides with different wavelengths. Based on these results, it can be concluded that aeration treatment provides better results for the observed variables than non-aeration. Keywords: Compost tea, humid acid, liquid organic fertilizer, lotus, nutrient content.
