Abstract

:  This study aims to determine the quality of compost of a mixture of Oyster Mushroom Baglog waste and Cow Manure, using Promi (Promoting Microbes), MA-11 (Microba Alfaafa-11), and BPF (Phosphate Solubilizing Bacteria) decomposers. The experiment was arranged in a Completely Randomized Design (CRD), consisting of 4 ( Four) treatments: P0 = Baglog Oyster Mushrooms and Manure with a ratio = 1:2 without decomposers, P1 = Baglog Oyster Mushrooms and Manure with a ratio = 1:2 plus Promi, P2 =Baglog Oyster Mushrooms and manure with a ratio = 1:2 plus MA 11, P3=Baglog Oyster Mushrooms and Manure with a ratio of = 1:2 plus (BPF). Each treatment was repeated three times to obtain 12 experimental units. Parameters measured were: texture, pH, C-organic, N-total, C/N Ratio, Temperature (Temperature), Compost Color, and Compost Odor. The results showed that of the three decomposers used in this study, Promi was better at decomposing compose for two months. Promi is faster in changing the color of the compost to black, faster in reducing the temperature of the compost, has a pH of 6.81, and has the lowest organic C content and total N content of 0.94%. Of the three decomposers used in this study, Promi is better and faster for producing compost from a mixture of baglog and cow manure than the other treatments.

Abstract

Changes in land cover that occur from year to year continue to increase. Human activity, especially in the utilization of natural resources, especially forests for various purposes, resulted in an increase in open land as well as critical land. As a result, the upstream watershed area which originally had an important role for the hydrological cycle, gradually decreased its function and ability as a catchment area. The purpose of this writing is to find out the status of land cover in the main watershed of the Lombok island on the class of land cover that applies universally, and examine its potential as a cause of drought on the island of Lombok. This research was conducted using the descriptive method, through the following stages, namely (i) secondary data collection, (ii) data analysis and (iii) data interpretation. This research was conducted from March 2023 to June 2023. The research area covers the island of Lombok. The four main watersheds (DAS), namely Dodokan, Menange, Pustik and Jelateng. Data 12 Land cover, namely Evergreen/Deciduous needieleaf, Evergreen broadeaf tress, Deciduous brodeaf tres, Mixed/other tresses, Shurbs, Herbaceous vegetation, Cultivated and manged vegetation, Regularly flooded vegetation, Urban/built-up, Snow/ice, Barren, Open water downloaded from the wibe site earthenv.org.

Abstract

This study aims to determine the value of the physical and chemical properties of the soil association hapludands-eutrudepts on ex-mined pumice land and non-mined land. This research was conducted in the District of Montong Gading and the Physics Laboratory and Soil Chemistry Laboratory, Faculty of Agriculture, University of Mataram in July 2022. The method used in this study was a descriptive method with survey techniques in the field accompanied by soil sampling supported by soil analysis in the laboratory and data collection. secondary data are land use maps and administrative maps. Parameters of soil physical observation are soil texture and porosity. Parameters observed in soil chemistry were pH (Electrometric Method), total-N (Kjedahl Method), available-P (Bray II Method) and K-exchanged (pH 7 Extractor). The results showed that the soil at the study site had a sandy loam and loamy sand texture and had relatively the same porosity level. The research soil has a slightly acidic pH except for the non-mined service which has a neutral pH, nitrogen content of the research soil had low nitrogen content on non-mined land and very low on ex-mined land, phosphor content The research soil has a very high phosphor content except for ex-mining plantations which have high phosphor and potassium content of Pelitian soil has moderate potassium content except for ex-mining settlements which have high potassium.
