Identification and Decomposition of Five Dominant Wild Plants From Acid Swampland in South Sumatra

There were five emergence plants in swampland such as Polygonum barbatum, Neptunia prostrata, Phragmites karka, Ludwigia adscendens and Phragmites communis, which might be used for compost source, all the plants were easily adapted and grew very well on acid soil.  These plants were choosen because of abudancy and size. All plants were identified, collected, chopped and weighted then put in a 50 liters plastic drum for decomposting during 12 weeks. Composts temperature were monitored every week, nutrients content (N, P, K, Ca, Mg, Na) and compost chemical properties (C-organic, C.E.C., C/N ratio) were analysed every two weeks. Results showed that each compost from different plant varied in nutrients content and chemical properties.  Compost made of Neptunia prostata Lam. contained highest nutrients than others, it’s nutrients were N (4%), P (1675 mg kg-1), K (5.6 %), Ca (0.32 %), Mg (0.32 %) and Na (0.12 %) and the lowest nutrients content showed by compost of Phragmites karka Retz. in which N (2.4 %), P (1160 mg kg-1), K (2.62 %), Ca (0.04 %), Mg (0.07 %), and Na (0.03 %).  It seem broadleaf plants tended to have higher nutrients content than grasses or graminae. Neptunia prostrata compost had a high N content due to it’s leguminosae plant. Al and Fe were low in all composts, therefore all plants were recommended for organic nutrient sources.

Peningkatan Kualitas Citra Digital Menggunakan Metode Super Resolusi Pada Domain Spasial

Citra merupakan salah satu komponen dari multimedia yang memegang peranan penting karena mengandung informasi dalam bentuk visual. Tetapi tidak semua citra dapat menampilkan informasi secara jelas dan detail seperti halnya citra resolusi rendah. Citra resolusi rendah memiliki kepadatan piksel yang rendah. Untuk itudiperlukan peningkatan kualitas citra menggunakan metode super resolusi agar dihasilkan citra resolusi tinggi dari citra resolusi rendah. Penelitian ini menggunakan teknik super resolusi yang melalui tiga tahapan umum yaitu registrasi, interpolasi (bilinear dan bikubik), dan rekonstruksi (smoothing dan denoising). Teknik ini diterapkan pada domain spasial menggunakan citra grayscale resolusi rendah. Teknik super resolusi ini diaplikasikan pada citra satu framedan citra multiframe. Hasil Mean Opinion Score (MOS)menunjukkan bahwa citra multiframe yang melalui prosesregistrasi menghasilkan citra resolusi tinggi yang lebih baikdibandingkan dengan citra satu frame tanpa proses registrasi

The Influence of Phosphate Fertilizer and Plant Growth Regulators on the Growth and Yield of Ratoon Rice (Oryza Sativa L.) Grown on Swampland

This research aimed to study the influence of phosphate fertilizer and plant growth regulator applications on the growth and yield of ratoon rice grown on swampland. The research was conducted in September 2016 to January 2017 at the greenhouse of Department of Soil Science, Faculty of Agriculture, Sriwijaya University. Soil characteristics were analyzed in the Laboratory of Chemistry, Biology and Soil Fertility, Department of Soil Science, Faculty of Agriculture, Sriwijaya University. The experiment was arranged in a factorial Completely Randomized Design. The first factor was the phospate fertilizer dosages, i.e. 150 kg ha-1 (P1), 200 kg ha-1 (P2), 250 kg ha-1 (P3). The second factor was the plant growth regulator treatments, consisting of control (Z0), Cytokinin 20 ppm (Z1), Gibberellin 60 ppm (Z3). The results showed that the application of P fertilizer did not affect the yield and growth of ratoon rice. However, the application of Plant Growth Regulators resulted in a significant effect on the growth and yield of ratoon rice. The application of Plant Growth Regulator of Gibberellin with the dosage of 60 ppm was able to increase the percentage of filled grains (84.93%), decrease the percentage of empty grains (15.07%), increase the weight of 100 grains (3.63 g) and increase the dry weight of milled grains (7.80 Mg ha-1). It is suggested that the treatment resulted in better plant growth and yield obtained in the current study might be recommended for ratoon cultivation in swampland

A systematic review of clay shale research development for slope construction

The issue of stability controlling cutting slopes is particularly important in clay-shale slopes, a typical expanding sedimentary layer with poor engineering geological conditions and mechanical characteristics. Therefore, research on the causes of failure and remedies for clay-shale cutting slopes is required to serve as an overview for handling and preserving clay-shale slopes in identical conditions. However, the trusted information about the need for further related clay shale research and clay shale in slope stability has yet to be specifically presented. This review study summarizes the published research for clay shale beginning in 1980, presents a bibliometric analysis to examine the published research based on year and country, and provides various study trends in cluster diagram using the VOSviewer program. The analysis also summarized some key goals, effective methodology, and significant findings from the most recent studies to extract information from them that would benefit future research. In conclusion, the results show the need for developing research to fill the knowledge gap regarding clay shale, landslide, and clay mineralogy. In addition, the clay shale slope analysis has revealed the need for additional research into dynamic force and its deformation
