Abstract

This study employs the Okada Method to analyze the horizontal seismic deformation of the Palu earthquake on September 28, 2018, with a magnitude of 7.5 Mw. Data from InaCORS stations (WATP, CPRE, CPAL, TOBP, and CMLI) strategically positioned near the earthquake epicenter were processed using Gfortran software, and deformation was mapped using GMT software. The analysis focuses on the 100 Days of Year (DOY) period from August 6 to November 28, 2018. Results indicate that during the co-seismic phase (DOY 272), InaCORS stations experienced deformations ranging from 477.130 mm to 7.7852 mm. The magnitude of deformation varied based on station proximity to the epicenter, with the largest displacement observed at TOBP and the smallest at CPRE. Station movements were divergent, with northern stations shifting northward and southern stations moving southward. Subsurface slip reached 1449.23 mm, affecting an area measuring 145 km by 76 km at a depth of 8 km, dip of 65˚, strike of 351˚, and rake of -46˚. These findings contribute valuable insights into the seismic impact on the Earth's crust, aiding seismic hazard assessments in the region

Abstract

Amaranth is a plant that has calcium oxalate content in leaves. One of the roles calcium oxalate in plants is to increase drought tolerance. In addition, amaranth leaves also have anomocytic stomata. Stomata plant leaves are known to be formed genetically and not affected morphoanatomically under drought stress conditions, except density and conductance. Therefore, the research aimed to find out how the response of calcium oxalate levels and stomata of amaranth leaves (Amaranthus tricolor var. Red Giti) under drought stress. The research method used was a randomized block design (RBD) with two treatments, which are watering every day (WD) and watering at 50% wilting (SD) by observing stomatal density (stomata/mm2) and calcium oxalate content (%). Data were analyzed statistically with independent T-test and chi-square. The results showed that stomatal density and calcium oxalate content were affected by drought stress with a significantly decreased response. This indicates that the amaranth plant may become a plant that is resistant to drought stress by decreasing stomatal density and calcium oxalate levels.

Abstract

The potato plant (Solanum tuberosum L.) is a perennial crop that contains high amounts of carbohydrates, minerals, and vitamins in its tubers, making it a carbohydrate-rich alternative food to rice or corn. One of the diseases that often appear on potato plants is potato rot caused by pathogenic molds. This study aims to isolate and characterize pathogenic fungi that cause blight on potato tubers based on Koch's Postulates. Potato pathogenic molds were isolated from potato tubers that had been rotted, then the molds were grown on PDA and purified twice. The purified isolates were then inoculated onto 30 healthy potato tubers and incubated for 7 days. Healthy potato tubers experienced the same symptoms as potato tuber rot. The isolated pathogenic fungi were then characterized so that the pathogenic fungi of Phytophthora infestans were obtained. In this study, Koch's Postulate method was successfully applied to isolate and characterize the pathogenic fungi that cause potato tuber rot. The pathogenic fungi caused a potato tuber rot disease incidence value of 100% with a disease severity value of 60.7%. The two factors that determine the disease incidence and disease severity values are internal factors (genes and traits of the pathogen) and external factors (environment).
