Abstract

The aim of this research is to provide information on the development of research results regarding technology in reducing greenhouse gas emissions in lowland rice cultivation in Indonesia. The method used is a narrative review with a limit of taking articles from 2003 – 2023. The results of the literature review of the articles obtained were grouped into five categories of technology types, namely low emission varieties, land processing, soil fertility management, irrigation management, use of greenhouse gas reducing bacteria. The information obtained in each category is still limited and does not yet describe integrated cultivation technology in reducing greenhouse gases. From this research, it is recommended that research development related to low greenhouse gas varieties, land processing, recommendations for organic and inorganic fertilization, irrigation and the use of greenhouse gas reducing bacteria still need to be carried out in order to achieve the target of reducing greenhouse gas emissions in Indonesia.

Abstract

Inulin is a type of prebiotic that has been studied to be useful in increasing the growth of several fish species. This research was carried out to evaluate the effect of inulin supplementation on the abundance of lactic acid bacteria in the intestine, growth performance and feed utilization including weight growth, specific growth rate, and feed conversion ratio of tilapia (Oreochromis niloticus) fingerlings. Ten tilapia fish with an average weight of 4.41 ± 0.52 g were reared in plastic tanks with a volume of 30 L for 30 days. During rearing, tilapia are given commercial feed with inulin supplementation as a treatment, namely: 0.0; 1.5; 3.0 and 6.0 g/kg feed, three times a day ad satiation. The data obtained in this study was tested statistically using the one-way ANOVA test and Tukey's advanced test. The results of the study showed that the inulin supplementation treatment of 1.5 g/kg feed provided the highest abundance of lactic acid bacteria at the end of the study, the highest weight growth, specific growth rate and lowest feed conversion ratio (P<0.05) compared to other treatments. The highest total gut bacteria of tilapia fry at the end of the study was shown at a treatment dose of 3.0 g inulin/kg feed. Based on this, inulin at a dose of 1.5 g/kg feed can be used as a prebiotic for tilapia seeds to support their growth and feed utilization.

Abstract

This research aims to determine the effect of types of soil processing and potassium dosage on the growth and yield of sweet corn plants in ultisol subsoil soil. The experiment used a Split Plot Design with 3 replications. The main plot is a type of land cultivation consisting of 3 levels, namely: no tillage, minimum tillage, maximum tillage. As a subplot, the dose of potassium fertilizer consists of 4 levels, namely: without fertilizer (control), dose 75 kg/ha, dose 150 kg/ha, and dose 225 kg/ha. The research data was analyzed using Diversity Analysis to find out whether the treatment had a real effect or an insignificant effect. If the results of the analysis have a real or very real effect, then continue with the Duncant's Multiple Range Test (DMRT) at the 5% level.This research concluded that: maximum tillage had a significant effect on plant height at 8 wap, number of leaves in the flowering phase, and ear circumference, and was very significant on leaf width, weight of husked cobs per plant, and weight of husked cobs per sweet corn plant planted in ultisol sub soil. The dose of potassium fertilizer of 225 kg/ha had a real and very significant effect on the variables of plant height at 4 wap, 6 wap, 8 wap, weight of cobs with husks and weight of cobs without husks. gave plant heights of 4 wap, 6 wap, 8 wap, highest cob weight with husks and cob weight without husks in sweet corn planted in Ultisol subsoil soil. The interaction of the type of soil processing and potassium dose influences the weight of cobs with husks per plant and the weight of cobs without husks per plant. The maximum type of tillage and a potassium dosage of 225 kg/ha provide the highest weight of husk-free cobs per plant and the highest weight of husk-free cobs per plant.
