Abstract

AbstractTondano River is an outlet of Tondano Lake played important roles in the life society of North Sulawesi Province. More increase the population growth, more increase the needed of people to that river, so that more increase the problems, such as sedimentation process occurred as the waste/erosion discharge existed at the Tondano estuary. The problemis the processes of sediment discharge could be used as media for planting and the water hyacinth as compost. The objective of this research was to know the responses of given the water hyacinth compost on the sediments of Tondano Watershed with indicator of corn crop (Zea mays sp.) on the field. Methods were used Randomized Block Design, consisted of some treatments, i.e.: ST0 as control, ST1 – compost of 10 t/ha, ST2 – compost of 20 t/ha, ST3 – compost of 30 t/ha, in three groups as for 12 experimental plots. Results showed that, given the water hyacinth compost on the sediments of Tondano River gave the significant effect for corn growth, that is, the treatment of 30 t/ha.  Keywords: sediment, water hyacinth, compost, TondanoWater shed.

Abstract

ABSTRACT  The watersheds is an ecosystem and the main elements of this ecosystem are natural resources (land, water and vegetation) and human resources that utilize natural resources. Regarding with the relationship between watershed and irrigation as one component in the water resources management, watersheds determine the availability of irrigation water when the watershed ecosystem is disrupted. In this condition, the water supply for irrigation decreased and therefore the agricultural productivity reduced. The area of the Lelema Watershed is 3,095 ha with a main river as long as 12,787 m that ends in the main river of Nimanga. The irrigated area of the Popontolen village is geographically located in the irrigation area  of Popontolen Village that is located at 1o15'47 "- 1o16'40" LU and 124o36'20 "- 124o38'00" BT. The area of Popontolen irrigation is 121.20 ha and consisted of primary, secondary and tertiary channels. In conclusion, the carrying channel in the irrigation area of the Popontolen Village is 7,468 meters and the length of primary and secondary carrier channels are 213 and 3,131 m, respectively.  Keywords: Lelema Watershed, Technical Irrigation, Geographic Information System.

Abstract

ABSTRACT  Curly chili (Capsicum annum L.) is one of the many horticultural commodities needed in daily life so that its needs continue to increase along with population growth and technological progress. One of the main pest species that attacks fruits and vegetables in Indonesia is Bactrocera sp. Methyl eugenol is reported sp to be able to control fruit flies in mango, guava, starfruit, melon, jackfruit, guava, tomato, red pepper and bitter melon. The aim of this study was to determine the level of fruit damage by Bactrocera sp. Fruit flies. in the use of methyl eugenol in curly chili plants in Tomohon City, especially in the villages of Kinilow, Kakaskasen, and Matani. The duration of the study lasted for three (months), namely from February to April 2018. This research was carried out by survey method or by direct observation at the research location.

Abstract

ABSTRACT Soil insects are insects whose part or whole life is in the soil.  Soil insects are used as indicators to determine the stability of an ecosystem, so this study aims to see the effect of the diversity of soil types on forest strata.  The Mahawu mountain protected forest is located in Tomohon, North Sulawesi Provinc.  Forests with altitude of 800 m to 1372 m above sea level, with forest area of 40.44 hectares.  The diversity of soil types of insects in protected forests of mahawu mountain is included in the medium category (1> H <3).  The highest number of insect populations was found in the two-storey forest floor of Family Dermaptera = 34 heads, one-strata forest of Gryllidae Family amounted to 26 heads, and three-strata forest of Cerambycidae family amounted to 15 heads. Keywords : Soil insects.

Abstract

ABSTRACT This study aims to study the effect of paclobutrazol on the growth and production of tomato plants. The research was conducted at the Experimental Garden of the Pandu Agricultural Technology Assessment Center in Talawaan Bantik Village, Wori District, North Minahasa Regency. Starting from September 2017 and ending in January 2018. This study used a randomized block design consisting of 6 levels of paclobutazol concentrations of 0 ppm, 75 ppm, 100 ppm, 125 ppm, 150 ppm, 175 ppm. Variables were observed for plant height, time / time of flowering (days after seeding), number of crop collections, and fruit weight. The use of paclobutrazol in tomato plants has a significant influence on plant height at flowering and number of leaves. The administration of paclobutrazol with a concentration of 125 ppm gave the greatest emphasis which produced the lowest plant height of 47.75 cm.  The use of paclobutrazol in tomato plants can delay the flowering process compared to without using paclobutrazol. The effect of paclobutrazol on flowering is a secondary influence, while the primary effect is suppression of vegetative growth. Keywords: Application of Paclobutrazol in Tomato Plants
