Abstract

Sustainable agriculture is not only limited to eliminating the use of agricultural inputs in the form of inorganic substances but in the form of utilizing local natural resources. The use of vermicompost and refugia plants is an alternative in organic farming. The purpose of this study was to determine the use of vermicomposts and refugia plants as inputs for organic farming in lowland rice. The study was carried out on a paddy pond in the village of Kuluran, Kali Tengah, Lamongan. The study used a randomized block design with treatment giving 20 tons ha-1 kascing and refugia plants on (P0) without chemical fertilizers, (P1) with the addition of 562.5 kg ha-1 NPK, (P2) adding 375.0 kg ha-1 NPK, (P3) addition of 187.5 kg ha-1 of NPK and (P4) addition of 750.0 kg ha-1 of NPK. All treatments were repeated 3 times. The results showed that the application of vermicompost treatment of 20 tons ha-1 and refugia plants without organic fertilizer gave the highest yield at the final plant height (118.61, cm) and the production of wet rice (13.28 tons ha-1).

Abstract

With the large need for organic fertilizer in fulfilling agricultural cultivation, vermicompost is a fast and appropriate way to utilize local natural resources in meeting the needs of organic biological agents. This study aims to determine the effect of giving organic fertilizer kascing with biological dimensions and chemical fertilizers (Urea, KCl, KNO3 Merah, and Phonska) with indicators of shallot plants. The study was conducted using a randomized block design, with the treatment of giving biological fertilizer with a dose of 30 tons/ha combined with chemical fertilizer with a dose (Urea 200 tons/ha; KCl 200 tons/ha; red KNO3 200 tons/ha, and Phonska 200 tons / ha Ha). The treatments P0 (without chemical fertilizer), P1 (25% of the dose of chemical fertilizer), P2 (50% of the dose of chemical fertilizer), P3 (75% of the dose of chemical fertilizer) and P4 (100% of the dose of chemical fertilizer). The results showed the availability of P-soil and C-organic soil after treatment were not significantly different. Observation of plant height also shows unreal results. While the number of tubers and production results obtained P2 gives the highest yield and is significantly different from other treatments.

Abstract

This area is a mangrove forest with a natural and high plant density. The existence of mangrove forest tourism activities allows human intervention in mangrove habitat, which will have an impact on carbon storage in the soil. This research aims to determine the carbon stock in the soil in the mangrove area of Wonorejo, Surabaya. The study was conducted by surveying the land by dividing the mangrove forest land into 4 zones based on a perpendicular coastline. Environmental observations include the number of plants and the physical and chemical characteristics of the soil. The results showed that the mangroves of the Avecennia family dominated the near-shore zone and the mangroves of the Rhizophora family dominated zones 3 and 4. The growth diversity of mangroves tended to be low in each plant family, while in each zone the diversity of mangroves was at moderate levels. In soil characteristics, the texture tends to be dusty and dusty clay, with high pH, EC and Redox values. The results of the measurement of carbon stocks in the mangrove forest area ranged from 1.04 to 1.45 Mg Ha-1.

Abstract

Forests are a store of carbon stocks, carbon is transferred from the atmosphere into the plant body through the process of photosynthesis. The occurrence of land conversion and land cover changes can cause the loss of carbon stocks, causing global warming. This study aims to identify changes in carbon stocks (C) due to land use change, as well as carbon emissions caused by the use of industrial forest land, dry land, and horticultural land in Bontang City, the part of East Borneo. Carbon stock in land consists of several components, namely soil carbon, top plant carbon, bottom plant carbon, litter carbon, and necromass carbon. The measurement results show that the largest carbon stock value is found in industrial forest land type 2 with a value of 158.54ton/ha. Carbon emissions occurred in the period 2009 to 2016 on forest land that was turned into type 1 industrial forest land, moor, and horticulture. The carbon emission that occurs is 34.09kton.
