Abstract

AbstractThe research aims to identify and describe the role of the agriculturalsector in the economy in Bitung City from 2010 to 2019 and its contribution tobasic sectors. The study was conducted for 3 months from June 2020 toSeptember 2020.The type of data used in this study is secondary data obtained from theCentral Statistics Agency (BPS) of Bitung City, namely in the form of GRDP ofBitung City and North Sulawesi Province for the period 2010 to 2019. Supportingdata is in the form of other secondary data relevant to this study, namely theresults -Research results, the data obtained were analyzed descriptively andpresented in tabular form.The results showed that the contribution of the agricultural sector to theGRDP of Bitung City in 2019 was 16.6 percent, although it has decreased since2010 by 17.8 percent, but the agricultural sector still ranks second after themanufacturing sector with a contribution of 32.84 percent in in 2019. The growthof the agricultural sector, although fluctuating, tends to increase from 6.33 percentin 2012 to 9.06 percent in 2019. The LQ value of the agricultural sector, eventhough it was less than one in 2019, was 0.85, but continues to increase comparedto last year. 2010 amounted to 0.75, and the agricultural sector, especially thecapture fisheries sub-sector, is the exporting sector to other districts / cities inNorth Sulawesi Province. Based on the results of this study, it can be concludedthat the agricultural sector has an important role in the economy of Bitung City,because this sector is not only an exporting sector, especially the capture fisheriessub-sector, but also as a provider of raw materials for the processing industry inBitung City.

Abstract

ABSTRACT This study aims to determine the effect of cow manure application on the growth of Pakcoy (Brassica rapa L.) on critical land in North Dumoga District, Bolaang Mongondow Regency. The study was conducted in a pot experiment with cow manure treatment consisting of 0 tons/ha as control, 15 tons/ha; 30 tons/ha; 45 tons/ha and Phonska 300 kg/ha. Number of plants per hole 2 plants. The incubation period for cow manure is 1 week. Research time for 2 months. The research method was an experiment with a completely randomized basic design (CRD) and 3 replications. The variables observed were plant height, number of leaves, and wet weight of pakcoy plants. Statistical testing for data that has been tabulated using Analysis of Diversity Fingerprint (Anova) and Analysis of the Least Significant Difference Test (BNT). The results of the study showed that the cow manure treatment had a significant effect on plant height, number of leaves and wet weight of pakcoy plants. The application of cow manure in the P3 treatment (45 tons/ha) gave the highest yield on plant height, number of leaves, and wet weight of pakcoy plants. Keywords : Cow Manure, Pakcoy, Critical Land

Abstract

Abstract This research aims to assess the value of soil erodibility in the Mount Masarang Protected Forest area Rurukan Village, Tomohon City. The research was conducted on 3 types of land cover, namely grasses/reeds land, agricultural land and secondary forests. For each type of land cover, 3 soil samples were taken. Soil sample points were determined purposively, the soil structure was observed and the soil permeability was measured using a permeameter with the constant water level method (Constant Head). Soil samples were analyzed in the laboratory to obtain data on soil texture and soil organic matter content, then K value was calculated according to the USLE method. The results showed that the highest soil erodibility was on agricultural land at 0.37 ton.jam.ft-tonf-1 .in-1 which is classified as a rather high class, while the lowest was on grass/reed land of 0.19 ton.jam.ft-tonf-1 .in-1 belongs to the low erodibility class. Factors causing high soil erodibility on agricultural land were a low clay content, higher silt and lower organic matter so that the soil is more easily eroded.Keywords: soil erodibility, protected forest, Mount Masarang.

Abstract

ABSTRAKRangrang ants are one of the non-timber forest product commodities from the fauna group. Weaverants have the benefit of regulating ecological functions as decomposers and help pollinate floweringplants. Economically, weaver ant eggs are used for bird feed. The research was carried out in theBatuputih Nature Park Forest, Bitung City, North Sulawesi Province, for one month in March 2019. Thisstudy aims to determine the type of host plant and the population of the number of weaver ant nests inBatuputih TWA. The method used is a systematic strip sampling by recording all trees that have nests andpurposively to determine the sample. The results of the study showed that there were 14 (fourteen) typesof weaver ant host plants, namely sempur (Dillenia indica L) 57, forest walnut (Canarium littorale BI) 48,titolang (Gastonia serratifolia Miq.) 40, noni (Morinda Citrifolia L.) 33, wood egg (Alstonia angustifoliaWall.ex A.

Abstract

ABSTRACTThis study aims to make an inventory of bird species in the KRMSP area, and analyze changesin the structure and composition of its bird species. This research was conducted in September 2020 atMegawati Soekarno Putri Botanical Garden, Ratatotok, Southeast Minahasa, North Sulawesi. Themethod used in this research was the IPA method (Indice Ponctuels d'Abondance) with priorityobservation points in the reclamation areas of years 2000, 2001, 2002, 2003/2004 and 2006/2007. Thisresearch covered a total of 15 observation points in 5 reclaimed areas. Results observed 896 birdindividuals, divided into 26 families and 44 species. Results were analyzed using the Shannon-Wienerdiversity index, resulting in a diversity value of 2.92. Comparative analysis of bird speciescomposition from 2008, 2009 and 2020 showed an increase on bird species and families as well as asignificant decrease in the number of individual birds observed. Comparison of Shannon-Wienerdiversity indices in years 2008, 2009 and 2020 show a moderate diversity value across all years. Thediversity index value in 2020 (2.92) is lower than in 2008 (2.94).Keywords: botanical garden, birds, comparative data.

Abstract

ABSTRACTThe purpose of this study is to analyze the irrigation network system of the PontakDam, North Bolaang Mongondow Regency based on geographic information systems. Themethod used in this research is the method of spatial analysis, namely a field survey by takingseveral measurements whose data is presented in the form of maps, tables and analyzeddescriptively. Information on the irrigation network of the Pontak dam has been presented ina spatial form in the form of a map of the irrigation network of the Pontak dam. The area ofPontak right irrigation network service is 131.63 Ha. If referring to the data from the PUPRService in the field of water resources, North Bolaang Mongondow Regency regarding thearea of rice fields in 2019 of 136.84 Ha, there is a difference in the area of rice fields of 5.21Ha. The index of the physical condition of the Pontak dam irrigation network is 93.44% witha weight of 42.05 infrastructure from a maximum value of 45.00, so routine maintenance isneeded.Keywords : Irrigation Network System, Geographic Information System

Abstract

ABSTRACTThe objectives of this study are 1). Calculate the flow rate of water. 2).Calculate the value of infiltration, percolation, evaporation and evapotranspiration.3). Make an irrigation design map for rice fields. This study uses direct datacollection methods in the field and uses secondary data. Collecting data directly inthe field and using secondary data. The results showed that based on secondarycalculation data, the water discharge value in December was 60.00 m3/second,January 97.5 m3/second and February 95.00 m3/second. Based on the data obtained,the average water loss due to infiltration is 9.64 cm/hour = 2.31 mm/day, percolationis 3.0 mm/hour = 71.9 mm/day and evaporation is 5.78 mm/day. To design anirrigation system, the effective water requirement for irrigating rice fields with anarea of approximately 50ha by reducing the initial water discharge with water lossdue to infiltration, percolation and evaporation by looking at the reference to existingdata, the results obtained are 37.88 m3/second to irrigate the land.Keywords: Irrigation, Map Design of Irrigation System
