Effect of Combination of Poultry Manure and Rice Husk Biochar on Soil Fertility and Rice Plants
Get PDFRice plants occupy a strategic position as a staple food producer for the people of Indonesia. Faced with limited suboptimal soil fertility, especially low levels of nutrients and soil pH, the use of organic fertilizers combined with local ameliorants is one solution to increase soil fertility. The purpose of this study was to obtain a combination of chicken or quail manure with rice husk biochar, which can reduce the use of inorganic fertilizers (urea, SP-36, and KCl). This study used a completely randomized design (CRD) consisting of 7 treatments (A, B, C, D, E, F, and G) which was a combination of 100% to 25% inorganic fertilizer of the recommendations, chicken manure or bird manure quail 5 tons/ha, and rice husk biochar 5 tons/ha. The parameters observed were plant height, total chlorophyll, seed dry weight, soil pH, soil NPK content, and Al-dd content. Observational data were analyzed with the F test at the 5% level then further tests were carried out using the Honest Significant Difference (HSD) test. The results showed that the treatments had a very significant effect, namely C, D, and E treatments resulted in a decrease in Al-dd, and an increase in K and had a significant effect on rice plant height. It was concluded that a combination of 5 tons/ha of chicken manure or quail manure with 5 tons/ha of biochar could increase soil fertility and rice plant height during the vegetative period and could substitute inorganic fertilizers up to 50% of the recommended dose

East Kalimantan is one of the provinces in Indonesia, and the Indonesian government does expect it to be the new nation's capital. This research is descriptive analysis research. This research aims to determine students' level of climate literacy in aspects of basic knowledge, attitudes, and behavior. The survey does conduct on 240 students of grade 12th students from eight different schools in East Kalimantan, Indonesia. The sampling technique is stratified random sampling. The research instrument used was a questionnaire divided into three aspects: basic knowledge, attitudes, and behavior. In the basic knowledge aspect, the questionnaire consists of 15 questions with a Guttman scale (true-false). Each questionnaire consists of 10 statements with a Likert scale in attitude and behavior. The results showed that students' level of climate literacy in the basic knowledge aspect was only in the sufficient category, and the attitude and behavior aspects were in the high category. Although, in general, the level of student climate literacy in the aspects of attitude and behavior is in the high category, there are still some students classified at the low level. We conclude that students' climate literacy still needs to be improved in terms of basic knowledge and aspects of attitude and behavior to prevent the future negative impacts of climate change
