Abstract

This study aims to determine the suitability of using cocopeat as planting media at transplanting containers in the polytube of the cempaka seedlings growth. The method used in this research was implementing a trial use of cocopeat as transplanting media in the polytube and being compared to the growth of cempaka seedlings in polytubes and polybags containing topsoil. The parameters observed included percent survival (%), height (cm), and diameter (cm) of the plants. Through the t-test it was shown that the parameters of diameter, height, and percent survival of the cempaka seedlings using cocopeat as a transplanting media were significantly different than those using top soil as a transplanting media.

Abstract

Fulfillment the needs of Red Jabon (Anthocephalus macrophyllus (Roxb.) Havil) seeds on the other hand can create an unbalanced ecosystem. The availability of red Jabon seed was becoming a source of food for pests, then it causes an explosion of pests and pathogens. The disease that most often affect red Jabon seeds, both in the nursery and in the field was red leaf spot (antraknose). The initial step to control red leaf spot disease is the identification of causing. Identification method performed by observation of the symptoms in the field, followed by microscopic observation in a laboratory. Based on the identification result, it was known that the disease caused by the fungus Cercospora sp., Colletotrichum sp. and Pestalotia sp. The effect caused by those fungal pathogens was the disruption of the photosynthetic process that ultimately inhibits the growth of red Jabon seeds. The controls which have been done are arranged the watering intensity, isolated the infected seed,and applied the chemical fungicide.

Abstract

Red Jabon is priority species that projected to be developed in plantation forests of North Minahasa Regency. Red Jabon is can adapt well various environmental conditions. The natural habitat of the red Jabon in North Sulawesi region was known in North Bolaang Mongondow. This study aimed to compare the growth of red jabon at the age of 1 year in North Minahasa Regency and North Bolaang Mongondow. The experiment was conducted in two (2) locations i.e. in Talawaan Village (North Minahasa Regency) and Nunuka Village (North Bolaang Mongondow). Two independent samples t test was conducted to determine the differences in height and diameter growth parameters at two test sites.The results showed that there was no difference in the growth of red Jabon between North Minahasa and North Bolaang Mongondow. The average height and diameter of red Jabon in North Minahasa Regency is at 215.84 cm and 4.34 cm, while the same parameters of North Bolaang Mongondow amounted to 231.79 cm and 4.14 cm. The development efforts on the plantations of red Jabon North Minahasa Regency need to be improved because of the environmental conditions in this region is very suitable for the growth of red Jabon.
