Abstract

Land susceptibility to degradation is characterized by the loss of topsoil due to erosion which is considered as a threat to agricultural productivity. Information about land sensitivity to erosion is crucial in determining the appropriate soil and water conservation techniques to avoid land degradation. This study, which was located in the Gandul Sub-Watershed, aims to analyze the level of land sensitivity to erosion in highland agricultural areas. Data analysis was carried out spatially using land system and land-cover maps. Soil and water conservation efforts were determined based on the land function and sensitivity. The land sensitivity to erosion in the Gandul Sub-watershed was categorized into 3 levels which were moderate (3.9%), high (95%), and very high (0.8%). There were various directions for Gandul Sub-Watershed management by considering the level of sensitivity of the land and the function of the area. Creating a ridge is one of the soils and water conservation practices that has been implemented for a long time by local communities as a soil erosion prevention. Keywords: agriculture, erosion, Gandul, sensitivity

Abstract

Selection parameter in coffee breeding for leaf rust (Hemeleia vastatrix) resistance is very important. Breeders used leaf-rust severity and leaf-rust incidence as parameters of direct selection. However, scientific proof is not yet available whether leaf morphology can be used as a parameter of indirect selection. The objective of this research was to seek the possibility of leaf morphology parameter and its ratio to be used as selection criteria through analyses of genotypic and phenotypic correlations of parameter of rust disease and parameter of leaf morphology and its ratio. The result revealed that genotypes showed significant variations in leaf-rust severity (5.21–25.84%), leaf morphology, and leaf-morphology ratio. Leaf length to leaf width ratio, leaf length to leaf area ratio, and leaf width to leaf weight ratio were not affected by the environment. Leaf-rust severity performed highly significant positive genotypic and phenotypic correlations the ratio of with leaf length to leaf area. For selection criteria, leaf-rust severity could be better used rather than leaf-rust incidence and branch-rust incidence. The ratio of leaf length to leaf area could also be used as an indirect selection criterion because the ratio showed a highly significant genotypic correlation with leaf-rust severity (rGab = 0.254**). However, the ratio of leaf length to leaf area is even better chosen for selection criteria rather than leaf-rust severity because the ratio was not affected by the environment. Keywords: fungus, Hemeleia vastatrix, indirect selection

Abstract

Efforts to increase production potential can be carried out by extensification in a less productive saline land. Salinity is a major problem in the growth of most plants. Azolla is a plant that is sensitive to salinity, but if it is applied well, it can grow optimally at high salinity levels. The purpose of this study is to obtain an azolla application technique that is effective in increasing the adaptation of rice plants to NaCl saline soil conditions. The experimental design used was Randomized Block Design (RBD) with 2 factors and 3 replications. The first factor was the azolla application technique consisted of 3 levels: fresh azolla composted, fresh azolla immersed, and fresh azolla as a ground cover. The second factor was the levels of NaCl salt stress consisted of 4 levels: control DHL 0, 2, 4, and 8 dS m-1. The adaptation ability of rice plants based on variable plants height growth rate, number of tillers, strove dry weight, root dry weight, stomata density, leaf chlorophyll (SPAD), age of flowering, number of paddy grain, and harvest index. The results showed how to test content up to 2 dS m-1 which increased rice growth especially the application of azolla composted. Increasing stress to 4 and 8 dS m-1showed bad effects on vegetative, physiology, and yields of rice components. The stronger of salt stress the higher all plants growth variables except the age of flowering that actually showed the acceleration of flowering. Application of composted azolla can increase the root dry weight and azolla as a ground cover can increase the numbers of paddy grains. Keywords: azolla, NaCl, rice, stress

Abstract

Application of fungicides to control rice diseases potentially have adverse effect on non target organisms including endophytic fungi. Unfortunately, information of fungicide effect on endophytic fungi on rice is still limited. The purpose of this research was to study the diversity and abundance of endophytic fungi on rice plant because of application of synthetic fungicides. There were two treatments in this study: non systemic fungicide (mankozeb) and systemic fungicide (difenoconazole) which were compared to control (without fungicide). Isolation of endophytic fungi and application of fungicides were conducted every week started at aged of 3 to 10 weeks after planting. Variables observed were total segment of rice colonized by endophytic fungi, colonization frequency of endophytic fungi, continued by identification and analysis of the diversity of endophytic fungi. This study showed that there was an increase in colonization of endophytic fungi with an increase of plant ages. The diversity of endophytic fungi was higher in stems than in leaves with the value of H' is 0.00-1.35 and 0.00-0.98 respectively. The most common types of endophytic fungi appear in each isolation of rice segments were Acremonium, Curvularia, Fusarium, Helminthosporium, Nigrospora, Penicillium, and Mucor. Both fungicides do not significantly affect the percentage of colonization and diversity of endophytic fungi. At the beginning of planting (4-6 MST) there was a decrease in the percentage of endophytic fungal colonization in the stem. From the percentage of colonization of each genus of fungi, Nigrospora and Fusarium decreased significantly with difenoconazole on the stem during the vegetative phase. Keywords: colonization, community, difenoconazole, diversity, mancozeb

Abstract

As Black Soldier Fly farming has become an emerging trend in Indonesia there is a new opportunity to take advantage from the waste generated from the activity. One of them is the exuviae, which is resulted from the emergence of the fly and it has a high chitin content. Chitin from BSF exuviae have low Cristalinity Indexes. Hence, it shows a promising potential to be processed to produce a new biopolimer. Therefore, converting chitin from BSF exuviae into chitosan using deacetylation process was studied. The researched variables were temperature and the duration of the process, which were studied at 50, 60, 70, and 80°C for 12 hours and 8, 10, 12, and 14 hours at 60°C, respectively. Chitosan produced in the temperature of 60, 70, and 80°C has met the standard quality, and the best duration of deacetylation process was 8 hours. The solubility test in acetic acid (2%) showed that chitosan solubility was increased with the increase of temperature, while it decreased as the duration of the process becomes longer. Moreover, the degree of deacetylation showed that chitosan was produced with the best quality in 80°C of temperature (75.98%) and 8 hours of deacetylation process (71.12%). Keywords: chitosan, degrees of deacetylation, exuviae of black soldier fly
