Abstract

Abstract This study aimed to identify the state of physical and chemical properties of the soil on the Cloves plant in the village of Tincep and Kolongan Atas Subdistrict Sonder.  This study conducted using a survey method with their implementation as follows: the soil samples were taken at two locations is overgrown Cloves plant with good growth rates and less well, each location was taken four soil samples, two soil samples were taken at Cloves plant with good growth rates and another two soil samples were taken on Cloves plant with less well growth rates.  Soil sampling conducted by digging a minipit with size 50 x 50 x 50 cm were taken at the canopy boundary of Cloves plant and the soil samples were taken top layer (horizon A) and lower layers (horizon B) which is based on the effect of organic matter on the soil layer (A and B).  The parameters observed was physical properties of soil that is, texture, structure, and consistency; and chemical properties of soil that is, nitrogen total, phosphor available, potassium available, c-organic, and pH.  The results showed clove plants with good growth and less well the specified visually not affected by the state of chemical of soil, but is influenced by physical properties of soil, because on the Cloves plant which less well grow on the horizon B was found weathered material.  Keywords: Cloves, Physical and Chemical properties of soil, Growth, Weathered material

Abstract

ABSTRACT  The purpose of this research is to estimate the amount of carbon stored in the biomass of mangrove forests in Blongko Village, District Sinonsayang, South Minahasa regency.The study was conducted over two months, from July to September 2014. This research method used 15 sampling plots 20x20 m2 each. Data Analysis used allometric equations to obtain the biomass of each species. Carbon store was assumed to be 0.47 factors of total biomass. The result showed that total carbon store and biomass were 17914.59 Mg and 8419.86 Mg with an average of 409.5 Mg ha-1  and 192.5 Mg ha-1 respectively.  Keywords: Carbon store, Biomass, Mangrove, Blongko Village, South Minahasa Regency.

Abstract

ABSTRACT The purpose of this study is to evaluate tumpara’s population and compare its density in each production forest and protected forests at Mount Tamata Siau Island. This study was conducted for one month in March 2014 at 7 plots in each forest type. Tumpara’s density and frequency was performed using sampling method and analized using descriptive statistics. Sightings density and frequency between production forests and protected forests then compared. Area description uses Importance Value Index (IVI). Correlation and simple regression analysis is used to see the relationship between vegetation and tumpara’s sightings frequency. Total basal area of the plots and shrub cover is used to evaluate tumpara’s sightings frequency. The results showed that the protected forest has tumpara density of 3.29 individuals/ha and 0.86 groups/ha while production forests has tumpara density of 2.14 individuals/ha and 0.47 groups/ha. Discovery frequency of tumpara in protected forest is 1.64 (0.02 to 3.26) times/day and the production forest has discovery frequency of 1.07 (0.21 to 1.93) times/day. There is a relation between vegetation cover and tumpara’s presence. The more area shrub covers, the higher tumpara population will be. Tumpara is more commonly seen in habitats dominated by Pandanus sp. Tumpara couldn’t be found in Myrstica fragrans dominated habitats.Keywords: Density, Sightings Frequency, Habitat, Tarsius tumpara, Siau Island

Abstract

ABSTRACTParticularly, the objectives of this research are to analyze between non-timber forest product (NTFP) contribution and one of social economic aspect (education) of Bukaka household farmers community. This study is located at Bukaka village, Kotabunan District of Bolaang Mongondow Timur Regency, North Sulawesi. Technically, indepth interview was used quastionaries method to 52 respondents which are taken from April to June 2014. However, the outcome of this study shows that NTFP contributes to the household income 25,16 % (Rp. 13.552.654 annualy) including 41,67% species of flora and 58,33% of fauna speciesfrom 12 species in total which are used by household. In conclusion, contribution of NTFP is not influenced by education level.Keywords: Contributions NTFPs, Income, Socio-economic aspect, Bukaka Village.

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 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
