Mucuna bracteata is a Legume Cover Crop (LCC) which has many advantages compared to other LCC. The generative propagation of M. bracteata is very difficult because of the seed coat is hard and thick, so that it has a long dormancy period and low germination. Germination without seed treatment, the germination ability only 12% to 18.33%. The efforts are made to break the seed dormancy by soaking the seeds in the sulfuric acid (H2SO4) to remove the lignin layer in the seed coat. The present study objective was to determine the appropriate concentration of H2SO4 for breaking dormancy of M. bracteata seeds. This research was conducted at the Laboratory of the 3rd Campus Andalas University, Dharmasraya, in April to June 2019 using a Completely Randomized Design (CRD) consisted of 3 treatments with 4 replications. The seed treatments were some concentrations of H2SO4 namely 3%, 4%, and 5%. The observed variables were T50 break dormancy period, germination ability, abnormal germination, dead seed, first count test, index value, and maximum growth potential. The observation data were analyzed by an F test at a 5% level, followed by the Duncan’s New Multiple Range Test (DNMRT) at a level of 5%. The results showed that soaking of M. bracteata seeds in H2SO4 with a concentration of 3% was the best treatment, a T50 value of 8.75 days after planting with a germination capacity of 78.50%.

The limitations of paddy fields can be overcome by the use of dry land through the application of the Aerobic Rice system. To increase rice production, the application of organic fertilizer is used as organic material that can improve the characteristics of dry land to nutrients available to plants. This study aims to determine the dose of goat manure that can increase the growth and yield of rice plants through the application of Aerobic Rice technology so as to be able to overcome the problems faced by people in Rejang Lebong District on land productivity and rice productivity. This study used factorial Randomized Complete Design, namely varieties and doses of goat manure on the Aerobic Rice system which were repeated three times. The results showed that real interactions were shown in the nine characters growth and yield observed, namely plant height, number of leaves, number of tillers, flowering age, harvest age, panicle number, panicle length and number of pellets and number of pellets per clump. The difference in varieties is clearly indicated by the eight characters of growth and results observed, namely plant height, flowering age, harvest age, panicle length, number of pithy grains, weighted grain weight and number of pithy grains per clump. The application of goat manure doses also significantly affected twelve characters observed such as plant height, number of leaves, number of tillers, age of flowering, harvest age, number of panicles, panicle length, number of rice grains, weight of grains, number of grains per clump, grain weight per clump and weight of 100 grains.

Penentuan status kualitas air berdasarkanstandar National Sanitation Foundation Water Quality Index (NSF-WQI). Penelitian ini menggunakan metode deskriptif untuk menggambarkan objek yang diteliti dengan data atau variable dan gejala atau keadaan, tidak dimaksudkan untuk menguji hipotesis tertentu. Hasil yang diperoleh menunjukkan kualitas air muara sungai Lais berdasarkan Water Quality Indexs (WQI) adalah pada kisaran normal (medium) dengan nilai 60 (50-70 normal). Namun untuk peruntukannya berpedoman pada Peraturan Pemerintah Nomor 82 Tahun 2001 tentang Pengelolaan Kualitas Air dan Pengendalian Pencemaran Air, dimana kriteria memenuhi baku mutu air kelas empat. Sehingga untuk saat ini belum memungkinkan dimanfaatkan bagi kepentingan perikanan karena masih tingginya fosfat 3.32 mg/l dan Facel coliform 6,755.56 jml/100 ml. Namun perairan muara sungai Lais memiliki potensi untuk dikembangkan sebagai lokasi kegiatan perikanan dengan perbaikan, pengelolaan dan infrastuktur dengan memperhatikan dimensi lingkungan secara kontinu serta mengikutsertakan peran aktif masyarakat sekitar. Sehingga perairan muara sungai Lais dapat bermanfaat bagi kesejahteraan masyarakat sekitar dimasa sekarang dan akan datang.Kata kunci: Water Quality Index, Potensi Peruntukan, Muara Sungai Lais

Mycorrhizae and PGPR (Plant Growt Promoting Rhizobacteria) are widely published in scientific research can increase crop production by optimizing nutrient uptake, but studies rarely combine PGPR bacterial groups with mycorrhizae in one application on one plant. Mycorrhizal fungi can help plants absorb phosphorus and water absorption while PGPR can provide nitrogen for host plants. The general objective of this research is to find an effective combination of mycorrhizae, PGPR and Fertilizers. While the specific purpose of this study is to look for the influence of mycorrhizae, PGPR and fertilizer in increasing the production of black soybean plants. The results showed that mycorrhizal and PGPR treatment had not been able to increase nutrient uptake of nitrogen and phosphorus so that the parameters of increased production such as the number of pods, pod weight, seed weight and weight of 100 black soybean seeds were not significantly different. Mycorrhizal, PGPR and fertilizer treatments were not significantly different, treatment between mycorrhizal, PGPR and fertilizer negatively influenced each other, mycorrhiza experienced competition between fungi in the soil, as well as PGPR experienced competition with other microbials that were in the soil or competition between mycorrhizae and PGPR. An effective treatment in increasing the production of black soybean plants is mycorrhiza without PGPR and added 25% fertilizer.
