Abstract

This study aimed to 1) Analyze several Pseudomonas fluorescens group’s ability to induce resistance of chili plants to yellow curly virus infection. 2) Analyzing the ability of several Pseudomonas fluorescens groups to stimulate the growth of chili plants. The experimental design used a completely randomized design (CRD) with four levels of treatment, namely : control (untreated chili plants), SKM1 (chili plants treated with Pseudomonas fluorescens group SKM1), MP1 (chili plants treated with Pseudomonas fluorescein group MP1), and MM2 (chili plants treated with Pseudomonas fluorescens group MM2). Bacterial treatment was carried out by immersing chili seeds into a solution of the Pseudomonas fluorescens group with a concentration of 109 CFU/ml. Virus transmission in chili plants was carried out naturally in areas of high yellow curly disease epidemics. The results indicated that chili plants treated with Pseudomonas fluorescens groups SKM1, MM2, and MP1 had increased resistance to yellow curly virus infection and decreased percentage of attacks from yellow curly virus disease. Chili plants treated with Pseudomonas fluorescens group MM2 showed higher plant’s height and more branches than those treated with SKM1, MP1, and control. Chili plants treated with Pseudomonas fluorescens groups MM2 and MP1 have faster flowering time than those treated with SKM1 and control.

Abstract

Sebangau National Park, in Central Kalimantan Province, is a wetland conservation area. In 2015, forest and land fires resulted in 455 hectares being burned. The identification of hotspots in this study is based on the number and distribution of hotspots based on satellite imagery data from the Moderate Resolution Imaging Spectroradiometer (MODIS) in 2001–2020. This study identifies hotspots by looking at the influence of rainfall and ENSO (El Nino Southern Oscillation) conditions. The method used is the method of spatial and temporal analysis. The aim of this study was to determine the characteristics of the hotspot distribution pattern in Sebangau National Park, Central Kalimantan Province, both spatially and temporally. There is a similarity between the temporal and spatial characteristics of hotspots in the number of significant additions to the number of hotspots in August, September, and October. The influence of monsoonal rainfall types and climates such as ENSO (El Nino Southern Oscillation) greatly influences the occurrence of hotspot events in Sebangau National Park, Central Kalimantan Province. The distribution pattern of hotspots in Sebangau National Park, Central Kalimantan Province, peaked in October, and the worst addition to the number of hotspots occurred in 2015, when these conditions occurred during the dry season and when the ENSO index (El Nino Southern Oscillation) showed +2.6, where these conditions included strong El Nino categories.

Abstract

The Banjarbaru administrative status has changed from an Administrative City to a City, and in 2022 become the Provincial Capital. Population growth and infrastructure/building development due to these changes may affect environmental changes. A significant increase in air temperature against its normal due to environmental changes can trigger climate change. Urban Heat Island (UHI) is a phenomenon recognized by the higher temperature conditions in urban areas compared to surrounding areas. UHI identification is known by calculating the difference in Land Surface Temperature (LST) values using remote sensing (satellite data). An increase in the value of LST in an area can trigger the appearance of UHI and make the environment less comfortable. The LST value is also related to population, vegetation, residential areas, and built-up land. Thermal Humidity Index (THI) is an index used to determine comfort level based on temperature and humidity conditions. This study aims to analyze spatiotemporal changes in UHI phenomena in the Banjarbaru area during three administrative status periods (1998 - 2022) and its effect on the comfortable index. This study uses Landsat satellite data (consist Visible, Near Infrared, and Thermal Bands) and Relative Humidity (RH) from 2 weather stations in Banjarbaru. The result shows that the distribution of UHI in the Banjarbaru City area increases around industrial areas, settlements, government centers, and along arterial roads that are open land without trees. In general, the Banjarbaru area experienced an increase in the comfort index. Initial conditions belonging to the comfortable and less comfortable classes changed to become less comfortable to uncomfortable, especially in the North Banjarbaru sub-district and around Syamsudin Noor Airport ( Landasan Ulin sub-district).
