Abstract

ABSTRACT Spiders (Araneae) are biological agents that are very potential in controlling insect pests in agricultural ecosystems. Pests are a cause of damage to plants, so pests that damage plants and can reduce production. Corn (Zea mays L) is one of the most important carbohydrateproducing food plants in the world, besides wheat and rice. The purpose of this study was to determine the type of spider in maize plantations in several villages in Minahasa Regency. This research was conducted in Sendangan Village, Sonder Subdistrict and Koyawas Village, West Langowan Subdistrict and Walewangko Village, West Langowan Subdistrict in Minahasa Regency. Materials and equipment used include 70% alcohol, mineral water plastic cups (240 ml), label paper, microscopes, Styrofoam food containers, skewers sticks, plastic ice cream bowls, stationery and corn planting areas. Pitfall traps are installed in the garden area, sampling is carried out after being installed for 2 days x 24 hours, spider sampling is carried out 3 times with an interval of one week per robbery per sampling. The results showed that (1) the type of spider that is in the planting of corn in several villages in Minahasa Regency has a very diverse species, the highest in Koyawas Village, then Walewangko Village, and the lowest in Sendangan Village and (2) The variety of cultivation methods and the circumstances surrounding maize play a role in determining the diversity of spider species. It is necessary to educate natural enemies on farmers so that farmers can reduce the use of chemicals that can threaten and kill natural enemies in the planting area. Keywords: spider, pest, corn

Abstract

ABSTRACT Awareness of health impacts through fruit consumption, demanded fruit yields to be always available, on the one hand the suitability of a plant requires different geographical conditions, this causes not all regions in Indonesia to produce various kinds of fruit. In land use planning, information of land potential is needed first, for specific use. This study aims to assess the actual and potential land suitability of mango (Mangifera indica),rambutan (Nephelium lappaceum), durian (Durio zibethinus), and passion fruit (Passiflora edulis) as well as to recommend suitable fruit plants to be cultivated in the study area. This research occurred in the plan area of agrotourism development PT. Bhineka Manca Wisata in Paputungan Village, West Likupang District, North Minahasa. Soil analysis was tested at the Soil Conservation Laboratory and Soil Fertility Laboratory, Department of Soil Science Faculty of Agriculture Sam Ratulangi University. The results showed the land with mixed forest land cover, has an actual land suitability class to mango, rambutan, durian, and passion fruit are marginally suitable. Whereas in the area of land covered by the bamboo forest, the actual suitability of the mango and passion fruit are marginally suitable, to rambutan and durian are moderately suitable. On land covered by shrubs, the actual land suitability class of mango, rambutan, durian, and passion fruit are marginally suitable. Keyword : Land suitability, fruits, agrotourism, West Likupang

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

Abstract

Abstract Drying a thin layer of cassava slices to the thickness of the slices is done using the Experimental Dryer. Drying is carried out at a temperature of 60 ̊C, observations are carried out every 15 minutes for the first 2 hours then every 1 hour until reaching equilibrium water content. The purpose of this study was to determine the drying characteristics of cassava slices and to determine the equation model between water content to time, drying rate to time, drying rate to water content, and analyze temperature changes in each sample in the dryer during the drying process. This research was conducted at the Post Harvest Laboratory of Agricultural Engineering, Faculty of Agriculture, Sam Ratulangi University, Manado. The research method uses experimental methods, observations and calculations are plotted in a graph and analyzed descriptively. Drying is done until the equilibrium water content. The tools used in the drying process are thermocouples, ovens, desiccators, analytical scale, digital scale. The material used cassava slices with 2 thicknesses are 3 and 6 mm. The results showed that during the drying process there were differences in temperature at 2 thicknesses. Mathematical model of the relationship of water content to time at a thickness of 3 mm is found in sample 2 with a moisture content reaching 1.6% WB after drying process for 7-8 hours with an exponential equation y = 28,602e-0,44x and R² = 0,8256 while at a thickness of 6 mm in sample 1 it reached 2% WB after drying for 11 - 12 hours with the exponential equation y = 41,161e-0.327x and R² = 0.8957. The drying rate model with at 3 mm thickness is with y = 52.336e-0.729x and R2 = 0.9613 and at 6 mm thickness the drying rate model with time is y = 31.845e-0.677x and R2 = 0.9826 while the model drying rate of water content at a thickness of 6 mm with y = 0.3119e0.0992x and R² = 0.7597. Keywords: Cassava Bulbs, Characteristics, Drying and thin film models.

Abstract

ABSTRACT The purpose of this study was to analyze the level of visitor satisfaction based on perceptions in the Mangowo Park Bahowo ecotourism area (MPB). The availability of information about the level of visitor satisfaction with the ecotourism area is expected to be an evaluation material for the manager in preparing the Mangrove Park Bahowo ecotourism development plan. This research was conducted in August-September 2019 in Bahowo, Tongkaina Village, Manado City. This research was conducted through a survey by filling out a questionnaire through interviews with 30 respondents. The data obtained were analyzed using the Likert Scale method. Based on the results of the study, the researchers concluded that MPB's natural beauty received the highest perception rating, which affected the level of visitor satisfaction giving the highest score on MPB view quality. The lowest level of visitor satisfaction for a variety of attractions, is related to the low visitor perceptions of ecotourism facilities and their arrangement.
