Abstract

The aim of this research was to analyze the physical and chemical properties of rice bran with husk addition. The percentage of husk addition was 0%, 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90% and 100%. Husks were grounded and mixed with rice bran homogeneously. The mixture was analyzed for physical properties, proximate analysis and van Soest analysis. The variables in this study included visualization of husk addition in rice bran, specific gravity (SG), bulk density (BD), moisture content (MC), ash, crude protein (CP), ether extract (EE), crude fiber (CF), acid detergent fiber (ADF), cellulose and lignin. Data were presented descriptively and the correlation between each variable was conducted. The results showed that there were differences in visualization in each level of husk addition in rice bran. The addition of husks in rice bran increased the ash (Δ = 11.89), CF (Δ = 22.75), ADF (Δ = 47.23), cellulose (Δ = 24.04) and lignin (Δ = 7, 40). The decrease in SG, BD, MC, CP and EE in mixing rice bran and husk were Δ = 0.62; 62.85; 3.64; 5.73 and 9.21 respectively. The correlation between the physical properties and the chemical properties showed significant correlation (p<0.01). The addition of husks to rice bran affected the physical and chemical qualities. Key words: chemical evaluation, husk, physical evaluation, rice bran

Abstract

Pathogen Botryodiplodia sp. is a fungus that causes dieback and stems rot diseases that attack forestry plants. The control currently being used in the field is using chemical pesticides, which are harmful to the surrounding environment and the plant itself, so there is a need for another alternative, namely using citronella and patchouli essential oils. Essential oils of citronella and patchouli have active compounds that act as antifungals to inhibit the growth of the pathogenic fungus Botryodiplodia sp. This study aimed to analyze the effect of citronella and patchouli essential oils on inhibiting the growth of the pathogen Botryodiplodia sp. in vitro. The results showed that the 10% patchouli treatment had the highest PDA and PDB media inhibition value. The lowest inhibition value was found in the 1% citronella treatment. The level of concentration, type of oil, and active ingredients contained in the oil affect the increase in effectiveness in controlling the pathogen Botryodiplodia sp. Keywords: antifungal, Botryodiplodia sp., citronella, in vitro, patchouli

Abstract

In rural areas, farmers face a significant challenge due to the lack of access to chemical analysis for feed ingredients. Therefore, there is a need for a new approximate analysis model that is lightweight and easy to apply. This study aimed to address this issue by utilizing bulk and tapped density analysis to estimate the composition of rice bran samples collected from 30 rural rice mill factories across 3 districts in Indonesia. The study used a correlation formula between bulk density values and tapped density values to estimate the crude protein and crude fiber contents of the samples. The study's results revealed significant variations (p<0.05) in the quality of rice bran due to various factors. Crude protein content significantly differed (p<0.05) across districts, with Bogor and Bandung having the highest values and Cirebon the lowest. Tapped density measurements generally yielded higher crude protein content values. Similarly, there were variations (p<0.05) in crude fiber content across districts and locations, with Cirebon having the highest values and Bogor the lowest. Tapped density measurements generally resulted in higher crude fiber content values, but there were significant variations observed in different districts and locations. The rice bran from the Bogor region showed indications of being of higher quality, with higher crude protein and lower crude fiber content compared to the other two regions.

Abstract

Controlled/slow-release fertilizers (CSRF) continue to be developed because of the need to increase agricultural productivity and reduce the economic, social, and environmental impacts of conventional fertilizers leaching into nature. Additionally, the use of biodegradable polymers as CSRF materials continues to be a priority in CSRF development. Therefore, this review synthesizes the current research on lignin- and polysaccharide-based CSRFs and emphasize their compatibility and performance in agricultural applications. Lignin, an abundant and renewable biopolymer, was evaluated for its effectiveness as a slow-release agent in CSRF. Studies have demonstrated the potential of lignin to improve nutrient release profiles and environmental sustainability when used alone or in combination with other polymers. Polysaccharides, which are known for their biocompatibility and biodegradability, have also been explored. The incorporation of lignin into polysaccharide-based CSRFs has been highlighted, particularly in starch, cellulose, chitosan, and sodium alginate matrices. These composites offer improved mechanical properties, controlled nutrient release, and enhanced soil water retention. The challenges and future directions regarding lignin- and polysaccharide-based CSRF are also reviewed. These findings underscore the importance of developing sustainable fertilizer technologies to meet future food demands while mitigating environmental impacts. Keywords: controlled/slow-rele ase fertilizer, composite matrix, lignin, polysaccharide, urea
