Abstract

ABSTRACTRice crops (Oryza sativa L.) is a crops that produce rice which is used as staple food of about 90% of Indonesia's population consumes rice. Pest is any organism that can interfere with the growth and development of plants so that the plants become damaged, stunted growth, and or death. Bedbug soil pest (Scotinophara coartata F.) is one of major pests that attacks rice crops and spread on planting rice in Sulawesi, Sumatra, Kalimantan and Java. This research aims to find out pest population S. coarctata in rice plants by plant age in some villages in the sub-district of North Dumoga, regency of Bolaang Mongondow. The research took place in sub-district of North Dumoga, regency of Bolaang Mongondow, which was in three villages, that is North Dondomon, South Mopuya and South Mopuya I, and the execution time was from October to Desember 2014. This research uses survey method with direct observation technique. Each village was taken three observation plot, and determined of five sub observation plot to be observed. The materials and tools used were rice crops planting, meter, plastic rope, bamboo poles, scissors, cameras and stationery. The research result shows that the population of soil bedbug (S. coartata F.) on the rice crops in sub-district of North Dumoga based on the age of the plant, the highest pest population was found in the age 42 hst is 4,15 tails, then in the age 28 hst is 2,81 tails and the lowest in the age 14 hst is 1,35 tails, and based on the location, the highest in the village of South Mopuya ie 3,07 tail, followed by the village of North Dondomon is, 2.67 tails and lowest in the village of South Mopuya I is 2,56 tail.Keyword: rice plants, soil bedbug, population

Abstract

ABSTRACT Sausage is a food that is popular and well known in all walks of life. Sausage is food made from finely chopped meat and spices given, entered into an elliptical wrapper in the form of animal gut or artificial wrapping with or without cooking, with or without smoked. Excipients commonly used in processed meat products are carbohydrates / starches. This study aims to fine the organoleptic characteristic  of sausages catfish mixed by sagoo baruk starch and purple sweet potato flour and preferred by the panelists. This study uses a completely randomized design with sago baruk starch treatment and purple sweet potato flour. The results showed that avarege values of sausage catfish using sago baruk starch and purple sweet potato flour for taste is 3,67 (like), tekstur 3,72 (like), colour 3,56 (like), and smell 3,66 (like), are liked by panelist    Keywords: sausage, catfish, sago starch baruk, purple sweet potato flour

ABSTRACTThis research was carried out from December 2012 to February 2013 at Mantehage Island. This research was aimed to describe the structure and composition mangrove vegetation at Mantehage Island. Mangrove ekosistem at Mantehage Island divided into seven segments according to the characteristic of the island. The methods used are plot sampling on systematic line. The results showed that mangrove in Mantehage concist of eleven species: Avicennia officinalis, Bruguiera gymnorrhiza, Bruguiera parviflora, Ceriops tagal, Excoecaria agallocha, Lumitzera littorea, Rhizophora apiculata, Rhizophora mucronata, Scyphiphora hydrophylla, Sonneratia alba, and Xylocarpus moluccensis. The highest importance value for tree were Bruguiera gymnorrhiza (97.33%), and Rhizophora apiculata (89.59%), for pole were Rhizophora apiculata (123.50%), and Rhizophora mucronata (70.59%), for sapling was Rhizophora apiculata (80.40%), and for seedling were Rhizophora apiculata (56.98%) and Bruguiera gymnorrhiza, (52.52%). At trees stratum, the segment D and E possessed higher species composition than other segments. The highest of frequency of occurance for trees were Bruguiera gymnorrhiza and Rhizophora apiculata.Key Words: Structure, Composition, Mangrove

Abstract

ABSTRACTThe study aims to determine the type and predators of insect populations in lowlandrice ecosystems in the district Tombatu Southeast Minahasa regency. The experimentwas conducted on the rice in the village Tombatu, District Tombatu, SoutheastMinahasa Regency. The research carried out by the survey on rice crops in the districtTombatu Southeast Minahasa District, the Village Tombatu One, Tombatu Two, andThree Tombatu. Sampling was carried out with a diagonal slice method thatestablishes five sub-plot that is on the corner and the middle of the sampling sites.Sampling was performed using insect nets swung over rice plant as much as ten timesthe double swing. Insects are netted immediately put into "killing bottle" thencollected in 70% alcohol to be identified. Identify the type of insect predatorsconducted using the facilities of Entomology and Pest Plant Laboratory, Faculty ofAgriculture UNSRAT. The research found seven insect predators with an averagepopulation Menochilus sp. (5.18 tail) Paederus sp., (3.34 tail), Agriocnemis spp. (2,24tail), Conocepalus sp. (1.10 tail), Ophionea sp. (0.68 tail), Sphecidae (0.52 tails), andLibelulla sp. 0.27 tails). On average the highest predator insect populations found inthe village Tombatu Two (4.55 tail), then the Village Tombatu One (1.07 tail) and thevillage of Three 0.91 Tombatu tail). The higher the age of the plant the morepredatory insect populations.

Each district is determined three sampling sites. Research using survey method in 4 districts, namely: (1) District of Salibabu, (2) District of Kalongan, (3) District of Lirung, and (4) District of Moronge. Each district is determined three sampling sites.Sampling method diagonal slices so that at each sample location consists of 5 sub-location. Searches conducted around the egg sample rod with a diameter of 0.5 meters and divide the four sectors/regions observations in the Northern, Eastern, Southern and Western.

ABSTRACT  The study aims to determine the effect of the concentration of spores of the fungus Beauveria bassiana against Aphis sp insect mortality in the laboratory. implementation of the research carried out for three months from July to September 2014. Research using the method Completely Randomized Design (CRD) with four treatments, using B. bassiana spores concentration of 104, 105, 106 and control. Plants used was pepper plants. Each plant with different spore concentrations, in use ten tail pest Aphis sp. Observations on doing every day for one week, with a look at the mortality of each treatment. The results showed that the test insect mortality was highest at day 4 observation with treatment reaches 106 (80%) at follow treatment 105 (52.5%) and treatment of 104 (0%). Observation day 5 mortality in the test insect reaches 106 treatment (20%), then treatment of 105 (32.5%), and treatment of 104 (10%). The results showed that the test insect mortality was highest at day 4 observation with treatment reaches 106 (80%) at follow treatment 105 (52.5%) and treatment of 104 (0%). Observation day 5 mortality in the test insect reaches 106 treatment (20%), then treatment of 105 (32.5%), and treatment of 104 (10%). Observation day 6 the highest mortality of test insects found in treatment reaches 104 (90%), treatment of 105 (15%), and treatment of 106 (0%).

Abstract

ABSTRACTThis research aims to study the incidence of disease in lowland rice tungro held in the District of West Tomohon, and lasted for 5 months from the month of November 2014 until March 2015. This study uses a survey or field observation purposive sampling with the object of research fields rice farmers in West Tomohon sub district, which is in the Village Taratara and Village Woloan. Each village was taken three plots groves and each plot was made sliced diagonally with five subplots with the size of each subplot that is 2 m x 2 m. At each subplot obtained 56 family of plants that was four weeks with a spacing of 15 cm x 20 cm x 40 cm (Legowo row 1: 3) of crop land, observations were made four times at intervals of one week. The results showed that characterizes the disease tungro rice paddy in the district of West Tomohon is infected plants tungro disease suffered stunted plant growth (dwarf), the color of the leaves turn yellow to yellow orange accompanied with brown spots on the leaves. Tungro disease incidence in rice crops in West Tomohon sub district amounted to 22:43%. Tungro disease vector Populations in West Tomohon sub district is 7.6 tail.Key words: Incidence, Disease Tungro, Rice
