Abstract

Sub watershed of Mowewe has been considered as important regions in South East Sulawesi because it takes a great responsibility as a water supplier in Konaweha watershed. Konaweha watershed is a source of irrigation and domestic water for Kolaka Regency, Konawe Regency, South Konawe Regency and Kendari Municipality which have been recently in a critical condition. For this reason, it should be well managed. This study was implemented with the aim of establishing model of land use in Mowewe sub watershed that can preserve the land and water resources. The method employs a system analysis with simulation technique by using the Universal Soil Loss Equation (USLE) model based on Geographical Information Systems (GIS). The result of the research revealed that the predicting soil erosion is 68,58 ton/ha/year, more than the Tolerable Soil Loss (TSL) value of 21,52 ton/ha/year. Therefore, restructuring of land use pattern should be done to improve the condition of the area to achieve a sustainability. Keywords : Watershed, land use, soil erosion, GIS

Abstract

Sub watershed of Latoma has to be considered as an area of the important regions in South East Sulawesi, because it takes a great responsibility as a water supplier in Konaweha watershed. Konaweha watershed is a source of irrigation and domestic water for Kolaka Regency, Konawe Regency, South Konawe Regency and Kendari Municipality which has been recently in a critical condition. For this reason, it should be well managed. This study was implemented with the aim of establishing model of land use in Latoma sub watershed that can preserve the land and water resources. The method employs a system analysis with simulation technique by using the Run-off Curve Number (CN) model based on Geographical Information Systems (GIS). The result of the research revealed that the run-off curve number is 70,34. It showed that maximum potential water retention or infiltration rate is 107,10 mm. Restructuring of land use pattern should be done to improve the condition of the area to achieve a sustainability objectives. Keywords : Watershed, land use, run-off curve number (CN), GIS

Mamahit JME, Manueke J, Pakasi SE.  2020.  Infasive pests fall army worm spodoptera frugiperda  (J.E. Smith) on maize in minahasa district. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-8 Tahun 2020, Palembang  20 Oktober 2020. pp. xx.  Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).The  fall army worm  Spodoptera frugiperda (J.E. Smith) (Lepidoptera: Noctuidae) is an invasive pest attacking maize plants in various regions in Indonesia. This pest is a very damaging pest of maize that originates from America and entered Indonesia on  2019  in the Sumatra region. The fall army worm  attack was reported in 13 provinces in Indonesia, including North Sulawesi. This study aims to observe the presence of fall army worm  in several maize plantations in  the maize production centers area, namely in Minahasa Regency, North Sulawesi Province, and to determine the intencity and damage of attack caused by S. frugiperda  on maize  plants. This study used a survey method with purposive sampling, to determine the location of maize plantations that were attacked by S. frugiperda. Furthermore, in the field, the symptoms of attack were observed and the incidence of attacks was calculated based on the presence or absence of attack symptoms, and calculated the level intensity of S. frugiperda pest attack. The results showed that S. frugiperda has distributed  in several maize plantations in Minahasa Regency, namely: in Langowan Utara, Langowan Timur, Langowan Barat, Langowan Selatan, Tompaso, Kakas and Remboken, with the intensity of attacks level  from low until severe. The attack percentage of  S. frugiperda from  30% to 70%.

Abstract

ABSTRACT Food Agriculture Land is a limited amount of natural resources, the increasing need for land resources by humans has given its own pattern of land use patterns in an area. Research conducted in the study area is to identify potential land for sustainable food agriculture, using the field survey method with land unit approach and land characteristics for maize (Zea mays L.) and cassava (Manihot) namely rainfall and slope. The results showed the total area of Mapanget Subdistrict was 5414.6 hectares, based on the results of the analysis showed the potential land for corn crops suitable (S1) 3886.75 hectares with a percentage of 71.76 of the total land area in Mapanget District, Land Quite Appropriate (S2) 470.56 hectares with a percentage of 8.75 of the area of land in Mapanget District, marginal land (S3) of 35.59 hectares with a percentage of 0.62 of Mapanget District area. Cassava Plants with marginal suitable land (S3) 4392.9 hectares with a percentage of 81.13 of the area of land in Mapanget District. Keywords: Availability of Sustainable Food Land, Land Area
