Abstract

ABSTRACT  Coconut is an important plant for human life. The whole part of the coconut can be use start for not unlit the fruit. The production of coconut is very important for human along with the amount of production that reduced due to pest attack. Another factor that can inhibiti the growth of coconut is a pest attack.  This research is to know the attack of beetle pest O. rhinoceros on coconut plant in Mapanget, Talawaan sub district, Minahasa Utara regency which is two place is Mapanget an Lanbow garden, during three months start from october to december 2017.  This research is use survey method or by direct observation.  The result of this research show percentage of pest attack on Mapanget garden by O. rhinoceros in firsh and two second egual to 60,45% and 60,76% and at the third egual 61,17%.  Percentage of pest attack on Lanbow garden by O. rhinoceros in the firsh and second month egual to 18,38% and 19,15% and then at the third month 20,19%.  Keywords: Percentage, O. rhinoceros, Coconut

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. Results of research on percentage of Bactrocera sp. in the land of methyl eugenol from the first and second weeks of 21.53% and 20.78%, while in the third week, the percentage of attacks was 18.86% followed by the observation of the fourth and fifth weeks increased by 24.34% and 33.86%. While the land of farmers experienced a decrease in the percentage of attacks from the first week, the second was 16.19% and 15.78%, then followed in the third, fourth and fifth weeks, the percentage of attacks increased by 17.47%, 18.54% and 18.7% . Whereas on land that is left to attack Bactrocera sp. from the first week of 16.09%, the second week was 21.9%, and in the third and fourth weeks the attack rate increased by 25.38% and 26.52%, followed by the fifth week of the attack level which increased to 30.56%.  Keywords: Percentage, Bactrocera sp.

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

Abstract

Abstract Walnut are native to Indonesia, which grows in many parts of the east, such as North Sulawesi and Maluku. Walnut shell is one of the Agricultural solid waste that has not been used optimally. Walnut shells have a physical structure that is hard enough to allow it to be used as charcoal, the use of walnut shells is still very lacking, so it takes the process of processing walnut shells into a more useful product. The purpose of this study is to make walnut shell briquettes and analyse content, ash content, briquette fuel that meet the Indonesian National Standard (SNI). The research was carried out for six months in two places, namely the Engineering Laboratory of the Faculty of Agriculture, Sam Ratulangi University Manado and the Laboratory of the Industry and Trade Standardization Research Institute.this study uses a descriptive method with different amounts of flour treatment (50 grams, 100 grams, 150 grams) and aims to observe the effect of adhesive material (tapioca flour) on the results of research, walnut shell briquettes have met the Indonesian National Standard (SNI). Keywords : walnut shell, tapioca adhesive, bioarang briquette

Abstract

ABSTRACTBirds are one of the biological wealth possessed by Indonesia. The presence of feed, nesting sites and stops is a factor that influences bird species' wealth at the local level. Birds are found in almost every place and have an important position as one of Indonesia's animal wealth. Birds also have a close connection with human life since time immemorial. This study aims to inventory and analyze the diversity of bird species and their abundance around the eyes of Bron water, Warembungan Village, Minahasa Regency. The study was conducted from August to September 2016 around the eyes of Bron's water, Warembungan Village, Minahasa Regency. Data retrieval is done by the IPA-Count method. The results of observations were found 49 species of birds from 26 families, with the Shannon-Wiener index value 2.44 as an indication of the diversity of species of birds around the Bron spring. Keywords : Birds, Bird species diversity, Around the Bron spring

ABSTRACT  This research aims to study the characteristic of the growth components of purple cornF1resulted from open pollinated between Yellow Manadocornandpurplecorn. Research carried out invillages ofKalasey 2,Mandolangsub-district,Minahasa regency, Province of North Sulawesi during 4 months from June toSeptember 2017.This research was arranged to describe the growthand yield characteristics of purple corn. Seed source used as the treatmentsis:U1 = The seed of purple corn from the fries ear, U2 = The seed of purple corn from the second ear, U3 = The Seed of purple corn from the third ear, U4 = The seed coof purple corn from the fourth ear, U5 = The seed of purple corn from the fifth ear.The results showed that the components of highplant andheight of ear position  plant height the highest is obtained from treatment U5 in contrast to the components in the diameter of the stem to be obtained from the U2 treatment being handed out. The coefficiency of variance of the growth and yield components showed low (less than 25%).  Keywords : corn characterization, purple corn
