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).

Abstract

Understanding the agronomic characteristics of sweetpotato grown in wetland is critical to optimise cultivation and maximise yield. By studying factors such as plant morphology and yield, as well as environmental conditions, is important to identify varieties and cultivation practices that are most suitable for specific agroecological zones. This research aims to study the agronomic characters of nagara sweet potato in South Kalimantan's wetlands and identify abiotic factors that support its growth. A total of 15 sweet potato accessions were randomly sampled in sweet potato cultivation hotspot areas in July 2024. Hierarchical cluster analysis was conducted to see the similarity of the accessions found. The results showed that the agronomic characters of sweet potato accessions differed from the registered variety (Ubi Nagara KB-1), especially in characteristics type & number of leaf lobes, shape and number of tubers. Sweet potato yield was also found to be lower (14 t ha-1) compared to Ubi Nagara KB-1 (20 t ha-1). Abiotic data were found to be favourable for sweet potato agronomy, except for pH. The accessions found are still recommended to be developed in lebak swamp land, due to their adaptability and potential which is still higher than sweet potato in general (in dry land). Genetic testing is needed to prove that morphological differences are caused by different varieties (genetic) or decreased environmental conditions. ABSTRAK Karakteristik agronomi ubi jalar yang ditanam di lahan basah sangat penting dipelajari untuk mengoptimalkan budidaya dan memaksimalkan hasil panen. Pemahaman faktor-faktor seperti morfologi dan hasil tanaman, serta kondisi lingkungan, penting untuk mengidentifikasi varietas dan praktik budidaya yang paling sesuai untuk zona agroekologi tertentu. Penelitian ini bertujuan mempelajari karakter agronomi ubi nagara di lahan rawa lebak Kalimantan Selatan dan mengidentifikasi faktor abiotik yang mendukung pertumbuhannya. Sebanyak 15 aksesi ubi jalar diambil secara acak di area sentra budidaya ubi pada Juli 2024. Analisis kluster hierarki dilakukan untuk melihat kekerabatan aksesi yang ditemukan. Hasil penelitian menunjukkan bahwa karakter agronomi aksesi ubi jalar berbeda dengan varietas yang terdaftar (Ubi Nagara KB-1), terutama pada ciri tipe, jumlah cuping daun, bentuk dan jumlah umbi. Hasil ubi jalar juga ditemukan lebih rendah (14 t ha-1) dibandingkan dengan Ubi Nagara KB-1 (20 t ha-1). Data abiotik ditemukan mendukung agronomi ubi jalar, kecuali pH. Aksesi yang ditemukan masih direkomendasikan untuk dikembangkan di lahan rawa lebak, karena adaptabilitas dan potensinya yang masih lebih tinggi dibanding ubi jalar secara umum (di lahan kering). Uji genetik diperlukan untuk membuktikan perbedaan morfologi disebabkan oleh varietas berbeda (genetik) atau penurunan kondisi lingkungan.

Abstract

The Urea and SP-36 dosages in this study mean to discover how it affects sorghum growth in Ultisol soil, using a factorial randomized block design with two components employed in the investigation. The first consideration is the urea dose (u), which consists of four treatment levels.:  = 100 kg ,  = 150 kg ,  = 200 kg , and   = 250 kg . The second factor is the SP-36 dose consisting of 3 levels: = 100 kg , = 150 kg , and  = 200 kg . The observations include plant height (cm), leaf area per plant ( ), shoot dry weight (g), root dry weight (g), final vegetative shoot-root ratio, and final generative shoot-root ratio. The results indicate that the interaction of Urea and SP-36 did not significantly affect all variables.  However, the single factor of Urea significantly affected the final vegetative shoot-root ratio, while SP-36 significantly affected the plant height at 63 days after sowing.
