Abstract

Abstract This research aims to acknowledge soil fertility of land for the development of Hebras (Gerbera jamensonii) decorative plant in Lansot district, of South Tomohon also to support Tomohon government programs for City of tourism and City of flowers. Soil fertility observed to soil physics to wit texture and soil permeabilities and soil chemical properties is pH, Organic Materials, nitrogen, phosphor, and potassium (K). The study was carried out during September to November 2019 in two places that are Lansot District, of South Tomohon to take the samples and Soil Science Laboratory Faculty of Agriculture, Sam Ratulangi University Manado to analysis the samples. The method used in this study is survey method by took the samples using Land use maps and the data are discussed descriptive. The final result by this research are showing that the soil in Lansot District of South Tomohon has silt loam texture and it has moderate permeability. Soil pH has a slightly sour criteria for range 6,19 – 6,35. Low and high levels of organic materials, N content is available medium, medium P and K is available in sufficient soil. The conclusion of this research it is known that soil fertility of the land for the development of Hebras (Gerbera jamensonii) houseplant in Lansot District of South Tomohon are suitable because the nutrients are readily available in soil. The development of the decorative plant will also support the City’s Government program of Tomohon as the City of tourism and the City of flowers.

Abstract

SUMMARY The purpose of this study was to determine the suitability of land for maize in parts of the Sea and Warembungan villages of Pineleng Distriet. The research method used was a survey method soil. Sampling is done based on land units. Land units are arranged based on land use, Slope and soil type. The results showed that the limiting factor is rainfall needs to be improved irrigation and soil conservation capacity, namely the making of drainage so that the actual land suitability after N will trun into a potential land suitability for class S2 and S3.

Abstract

ABSTRAC This study aims to determine the development of Abaka bananas (Musa textilis Nee) on Karakelang Island. The results of this study are expected to provide information, for Farmers in the Development of Abaca banana cultivation, on Karakelang Island. in addition, it can support the overall development of Abaca banana cultivation in Talaud Islands Regency. This research was conducted for three months, from December 2018 to March 2019, the location of sampling in Karekelang Island in three districts, namely: Essang District, Essang Selatan District, and Beo Utara District and in each subdistrict each was selected four Village. In each village there are ten Abaka respondents / farmers. This research was conducted by survey using a questionnaire with direct interviews to farmers. The results of the study show that Abaca (rotte) is an endemic Talaud plant which is very suitable for the climate and soil on the karakelang island, with the cultivation system of farmers still traditionally, There is no excessive treatment for Abaca bananas. Farmers intercropping with coconut and durian plants. Excellence Karakelang Island has five regional superior varieties. Planting distance applied by farmers varies greatly, namely 4m x 4m, 4.5m x 4.5m, 5m x 5m while others are still dependent on coconut and Durian as the main crop. Abaca on Karakelang Island can be cultivated at altitudes below 300 m asl which are found in the three research location Districts. Keyword: Potential, Abaka Banana, Development, Karakelang

Abstract

ABSTRACT Beanshave been known as a complementary source of protein with whole grains, such as rice and wheat. As the age of agricultural commodities grows there are serious problems that have been found, namely pests of diseases in agricultural crops. Disease pest attacks not only during growing process, but also after harvest. One of the warehouse pests that cause damage to the food commodity that is stored is Corcyra cephalonica. The aim of this research is to know the development of C.cephalonica population of Beans. The study was conducted at the Plant Pest and Disease Laboratory from March to July 2017. The observations were made after the eggs hatched and become imago. It has been counted every day of the population from C.cephalonica until it finished which is about 11 days of observation. The results showed that the red bean flour medium had the lowest average imago C. cephalonica population which is 7.28 individuals followed by green bean flour medium that was 8.36 individuals on average. Then on soybean flour media that is 9.52 individuals and on the highest peanut flour media is 9.8 individuals. Keywords : Beans, C. cephalonica

Abstract

ABSTRACT The research objective is to study the effect of Trichoderma sp mushroom dosage variations on the increase in seed germination of peanut plants was carried out at the Green House, Faculty of Agriculture, Unsrat. for 3 months, starting in June - August 2019. This study uses a completely randomized design method (CRD), with 6 treatments in a ratio of 1: 0, 1: 1, 1: 2, 1: 3, 1: 4, and 1: 5 The results of the analysis of varying doses of Trichoderma sp on peanut seeds showed a difference to the germination of peanut seeds compared with seeds that did not use trichoderma sp. This can be influenced by several factors that inhibit germination, namely internal factors including hormones, seed size, maturity, and dormancy. Seeds that are harvested before physiological maturity do not have high viability because they do not have sufficient food reserves and imperfect embryo formation. Key words:Trichoderma, peanuts

Abstract

ABSTRACT Tahuna is located on Sangihe Island which has a wealth of unique species of birds. Along the coast of Tahuna Bay there are three types of land cover namely the built area, coastal forest and mangrove forest, the difference in the existence of this area is followed by variations in the diversity of bird species, because found different types of birds from each type of habitat that made the observation point. The study was conducted at six locations using the point count method. This study aims to compare the diversity of bird species and communities in the built area, coastal forests and mangrove forests in Tahuna Bay. Data obtained from observations in the field will be analyzed with simple descriptive statistics and then displayed in tables and figures. Data analysis was performed to obtain species richness, diversity indexes, community similarities, and abundance and population. Data analysis was performed to evaluate species richness and density, biodiversity index, and community similarity. The results showed that in Tahuna Bay there were 27 species of birds from 15 families with the highest species richness in the Mangrove area which was low in human activity (15 species, 10 families) and the lowest wealth in the built area that was utilized for shops (5 species, 5 families) . The bird with the highest density in the Bay of Tahuan area is the Erasia Church Bird (Passer montanus) (K = 7.67 D / ha). Teluk Tahuna has a moderate species diversity index (H '= 2.28) with an evenness index from each observation point (E = 0.69). Natural areas (coastal forests and mangroves) have the highest community similarity value of (IS = 73%). Compared to the built area, which has the lowest community similarity value of (IS = 25%).

Abstract This study aims to determine the amount of red ginger juice concentration on the manufacture of coconut candy based on sensory tests. This study used a Completely Randomized Design (CRD) 4 treatment with 3 replications namely, A (4% red ginger juice), B (8% red ginger juice), C (12% red ginger juice), D (16% red ginger juice). Then a quantitative test for water content, ash content, and reducing sugar content is carried out, this is done for the most preferred sample. Based on organoleptic testing, the level of preference for taste, color, aroma, and texture of ginger coconut candy is accepted by panelists with neutral to like criteria. The most preferred ginger coconut candy is one made with a 4% red ginger juice concentration. Then a further test is done, namely 4.90% water content, 2.06% ash content and 7.24% reducing sugar content. Keywords: Coconut Candy, Red Ginger Juice, Palm Sugar
