Abstract

Composting liquid organic fertilizer, composting efficiency may be gauged using the variation in material volume with headspace. The purpose of this study is to ascertain how the ratio of materials to headspace affects the rate of composting and the quality of the POC that results, as well as to identify the ratio of materials to headspace that yields the best POC quality in accordance with the minimal technical POC requirements based here on Decision of the Minister of Agriculture of the Republic of Indonesia No. 261/KPTS/SR.310/M/4/2019. Composting uses an anaerobic system and the materials used are fruit and vegetable waste. The method used is a one-factor Completely Randomized Design.The factor used is the ratio of material and headspace, namely 1:5, 2:4, 3:3, 4:2, and 5:1. The five treatment were repeated 3 times to obtain 15 experimental units. The research parameters include the initial content of the material, total microbial bioactivator, temperature, pH, material height shrinkage, nitrogen, phosphorus, potassium, and C-organic content, C/N ratio, organic matter, EC, and total POC bacteria. Data obtained from observations were analyzed by ANOVA test and continued with Duncan's test. In general, the quality of the POC produced complies with the minimum technical requirements with POC temperature 29,3°C-29,8°C, POC pH 5,3-6,3, nitrogen content 2,01%-2,15%, phosphorus 2,02%-2,09%, potassium 2,03%-2,08%, C-organic 2,39%-3,69%, and total POC bacteria 5,31×107-3,12×109cfu/ml. The ratio of materials and headspace affect the rate of composting and the quality of the resulting POC. Treatment P2 (2:4) is the best treatment based on results of data analysis and parameters used.

Abstract

Cow urine has the potential to become biourin. This study aims to determine the effect of the type of diffuser on the quality of biourin, as well as to determine the best type of diffuser during the fermentation process. This study used a completely randomized design consisting of 5 treatments and 3 replications. Each treatment contained 10 liters of urine, 2% nitrifying bacteria, and 2% molasses. The treatment was carried out without aeration, treatment using aeration without a diffuser, treatment using a fine bubble diffuser, treatment using a coarse bubble diffuser, and treatment using an aerated stone diffuser. This fermentation was carried out for 20 days with measurements every 5 days. Parameters observed were temperature, pH, TDS, EC, C-Organic, N-Total, and C/N Ratio during the fermentation process. The results of the study showed that the use of several types of diffusers had a significant effect on the process of fermenting cow urine. The fermentation process without using a diffuser showed that as the fermentation time increased, the pH value decreased from 7.72 to 7.54. On the 20th day of bio-urine fermentation, the highest Biochemical Oxygen Demand value was shown by the treatment using a fine bubble diffuser with a value of 9.2 mg/l. Of the five urine fermentation treatments, only fermentation with a diffuser met standard No.70/Permentan/SR.140/10/2011. Treatment with a type of fine bubble diffuser is the best treatment.

Abstract

Blast disease is a disease that attacks the leaves of rice plants. Blast disease attacks can affect chlorophyll and the health of rice plants. Leaf chlorophyll can be estimated using a SPAD chlorophyll meter to obtain the SPAD value. The vegetation index v alue has a strong relationship with chlorophyll. This study aims to obtain the relationship between SPAD value and Vegetation Index value in rice plants affected by blast disease using multispectral imagery and determine the level of correlation between SP AD value and Vegetation Index value in rice plants affected by blast disease using multispectral imagery. SPAD value sampling was carried out on 3 rice field plots, each plot was taken 5 points diagonally, and each point was taken 9 rice paddy clumps. Next , multispectral image acquisition using the DJI Phantom 4 Drone with multispectral cameras at altitudes of 15 m, 30 m, and 45 m. The image is then mosaiced using Agisoft Metashape, then normalized with Photoshop. Next, the vegetation index analysis of NDVI , CI G , and SAVI using QGIS 3.16, followed by regression analysis between the SPAD value and the vegetation index value. The results of the analysis showed that the three vegetation indices at various altitudes produced a linear relationship and the degree of correlation ranged from strong to very strong. Strong correlation rate on NDVI 45 m (65.4%), SAVI 45 m (63.1%), and very strong correlation on NDVI index 15 m (94.2%), 30 m (79.5%), CI G 15 m (80.5%), 30 m (84.8%), 45 m (82.5%), and SAVI 15 m (80.5%), 30 m (78%). It can be concluded that the NDVI vegetation index with a height of 15 m provides the strongest correlation value
