Published: July 2023

Genetic variation is needed for developing new superior varieties in plant breeding. Genetic variation of chili plants could be increased by inducing mutation with gamma rays irradiation. The aim of this study was to determine radiosensitivity of two local varieties of chili pepper by calculating the lethal dose values at LD20 and LD50. Chili pepper (Capsicum frutescens L.) seeds of local varieties origin from Tulungagung and Ponorogo were irradiated with cobalt-60 gamma rays at doses of: 0; 100; 200; 300; 400; 500; 600; 700; 800; 900; 1000 Gray (Gy); each as many as 50 seeds per dose of radiation. The irradiated chili seeds were grown in small polybags containing 1:1 mixture of soil and compost. Germination parameters of chili seeds was observed 30 days after planting (DAT) to determine lethal dose of 20 (LD20) and lethal dose of 50 (LD50). The results showed that increasing doses of gamma rays caused greater damage to chili seeds therefore the seeds were not able to germinate. Local Tulungagung Variety had LD20 and LD50 of 147.62 Gy and 409.52 Gy; and the Local Ponorogo variety had LD20 and LD50 of 90.3 Gray and 453.7 Gray. Local Tulungagung Variety was more sensitive to gamma rays than Local Ponorogo Variety. LD20 and LD50 can be used to get a lot of genetic variation and obtaining the positive mutants.

Many watersheds in Manokwari are classified as flood-prone areas with a frequency of more than 1 flood per year. Limited rain stations and climate stations make it difficult to the zoning of flood-prone areas. This study aims to utilize remote sensing data and hydrodynamic models to zone flood-prone areas in watersheds (DAS). The research was conducted in the Wosi Watershed - Manokwari Regency - West Papua Province. The data used in this research is DEMNAS topographic data, Climate Hazards Group Infrared Precipitation with Stations (CHIRPS) data acquired 1996 – 2020, Sentinel 2 imagery acquired 21 September 2020, and river maps. The peak flow in the Wosi watershed was analyzed using rational methods and flood hazard zoning was analyzed using HEC-RAS. The research showed that the Wosi River was not able to accommodate the peak flow at various return periods, consequently, the Wosi River had the potential for flooding every year. The results of this study are relevant to actual events, therefore remote sensing data and hydrodynamic models can be used to analyze peak flow and flood hazard zoning.Keywords: Climate Hazards Group Infrared Precipitation with Stations, DEMNAS, HEC-RAS, Satellite Imagery, Sentinel 2.

ABSTRACTIn the 16th century, Kadaleman Kawasen became one of the government systems that was influenced by Mataram. The change of the kadaleman system into a village was influenced by colonial policies that spread its power to Priangan. This study aims is to describe the process of changing the Kadaleman Kawasen government system into a village named Kawasen Village and to describe the comparison of the two systems. The method is using the historical method with for steps. The first is heuristic, it means the source collection stage. The second is criticism, it means researching the source, criticism is divided into external critism and internal criticism. The third is interpretations, it means interpreting the source and the fourth is historiography, it means writing of history. Kadaleman Kawasen that had a district level position was abolished by the colonial government for some reason. Kadaleman Kawasen runs a government system under the reign of the Mataram Kingdom hegemony. The regent gains the position and power as a minor king who reigns in his territory with inherent privilages. While the Village Government systems was from changes in colonial policies that became their superiors. The form and structure of government is determined based on the customary law of each region.
