Abstract

The purpose of this study was to calculate the amount of water required during the growth phases of the rice var. Permata and Serayu with soil layer thickness of 25 cm and 35 cm.This research was conducted in September - December 2019 in Rasi Village, Ratahan District, Southeast Minahasa Regency. The research was carried out experimentally and the observed data in the field were analyzed descriptively. This study consisted of two treatment factors, i.e. variety (Serayu and Permata) and the thickness of the cultivated soil (25 and 35 cm). The rice plants were planted in and in theiron boxes (60 X 60 cm) in the paddy fields. The total Evapotranspiration or water requirement for rice planted the iron boxeswere188 and 254 L, respectively, for soil depth of 25 and 35 cm in Serayu. For the Permata variety with a soil depth of 25 and 35 cm, the water requirement were175 and 231L, respectively.

Abstract

Watersheds have some important roles for life in the vicinity, such as storing rainwater and flowing it as a water source. Disturbances in watersheds can causes soil erosion, which also causes the loss of fertile soil layers and carries solids and chemicals that can harm agricultural and human activities. Erosion prediction can be done by using the RUSLE method. The purpose of this study is to determine the rate of erosion in the rehabilitation area of the Bantik’s watershed. The result of this study is to indicate that the erosion in the rehabilitation area of the Bantik’s watershed is dominate by very light erosion with the lowest value around 1.04 tons/ha/yr and the highest value around 81.02 tons/ha/yr. It is necessary to take conservation measures on the soil and slopes so that erosion does not exceed its natural limits.

Abstract

Birds are one of the forest's ecosystem components which able to help in the forest's natural regeneration, with one of the bird's natural habitats being urban forests. This study aims to analyze the diversity and describe the bird's species in the Urban Forest habitat of the Kuwil Village of North Minahasa Regency. Data collection used survey methods with plots in form of 2 rectangular line transects with a length of 2000 m each and 20 m wide. Data collection is done 5 times. Based on the research, there were 10 species of birds with a diversity index of bird species as 1.98 which was in the medium category. The species found were Halcyon chloris, Corvus enca, Pycnonotus aurigaster, Oriolus chinensis, Gerygone sulphurea, Galliralus torquatus, Phaenicophaeus calyorhynchus, Eudynamys melanorhyncus, Geopelia striata, and Ducula aenea.

Abstract

This PKM activity is aimed at Catholic Women in Airmadidi, North Minahasa Regency. In the initial survey, the target community expects knowledge and skills about making organic fertilizers. Because it coincided with the pandemic, the implementation of PKM activities was carried out through the zoom application with the delivery of material by resource persons about the benefits of using organic fertilizers and the potential of existing resources around/around the environment that can be used as a source of organic fertilizer. After that, through a video, they demonstrated how to make organic fertilizer by utilizing existing resources. This training on making organic fertilizers needs to be followed up with mentoring activities during manufacture to further refine and maximize the results of the activities. In addition to household waste, various other biological sources can also be tried as a source of organic fertilizer. The community needs to get higher motivation so that they want to continue to make and produce and utilize organic fertilizers by utilizing the biological resources that exist around them
