Abstract

ABSTRACK  This research presents land cover conversions on Mount Tumpa Forest Park within the 2007-2014 period; what was converted, where it happened, and how big those conversions were. The results shows that there are six classes of land cover, namely secondary forest, teak forest, buses, farm fields, mixed plantation, and coconut plantation. That there were a variety of conversions between classes in all observed villages : (1) secondary forest to coconut plantation, mixed plantation, bushes and fields (5.90%), (2) mixed plantation to bushes (0.23%), (3) coconut plantation to mixed plantation (0.61%), (4) fields to mixed plantation, bushes and secondary forest (4.74%). Even though some areas classified as bushes and farm fields were converted into secondary forests, the conversion of secondary forests to other classes (coconut plantation, mixed 2  plantation, bushes, and fields) is bigger in comparison, thus causing a decrease of the forest area by 1.03 ha.Or  175.13 to 174.10 ha between 2007-2014.   Keywords: Forest area decrease, land cover conversion, GIS

Abstract

ABSTRACTLand cover of KPHP Poigar constantly has been changing. Mapping and identification by Maximum Likelihood method was more accurate than another method. Purpose of this research is to analyze the capability Maximum Likelihood Classification to map and identify the type of land cover in KHPH Poigar area. This research was carried out in September – November 2015 and in four steps. The first step was Image Pre-processing such a Layer Stacking process. Second step consists of OIF (Optimum Index Factor) Calculation, Cropping, and Visual Image Interpretation. Third step was Ground check in KPHP Poigar area. Fourth step were Image Analyzing with Maximum Likelihood Classification method and Accuracy Test. The value of accurate test for Overall Accuracy (OA) was 85,04 percent and for Kappa Accuracy (KA) was 80,97 percent classified into Almost Perfect Agreement category. The result of land cover classification based on image analyzing with Maximum Likelihood Classification method in KHPH Poigar indicated that there are 5 types of land cover, they are forest (21597,21 ha), bareland (5799,69 ha), bush (5612,58 ha), farmland (5649,12 ha) and mixed farmland (2942,37 ha).Keywords : Maximum Likelihood, KPHP Poigar, Type of Land Cover, Accuracy

Abstract

ABSTRACT Comforts could be defined as psychological and physical comforts. Psychological comfort could be perchieved by safety, peace, and relaxant feeling that felt personaly and subjectively measurable. In the meanwhile, physical comfort could be measured objectively such as spatial, visual, auditorial, and thermal. Open spaces are public space that accessible either directly within limited or indirectly within undeterminate period of time. Open spaces could appear as roads, sidewalks, urban spaces such as townparks, forests, and other similar things. This manuscript discussed about thermal comfort that felt by human whose had activity on an urban green space (Ruang Terbuka Hijau or RTH) of The University of Sam Ratulangi. This research aimed to studying respondent perceptions on the point of thermal comfort on The University of Sam Ratulangi’s RTH. This research used purposive sampling to select the urban green spaces which frequently accesed, while respondents are randomly chosen. These following 11 RTH known to be accessed frequently, they are FMIPA, FAPERTA, FAPET, BANK BNI, FPIK, FATEK, FEB, FISIP, FH, FKM A, and FKM B. This research concluded the most comfortable RTH based on respondent perceptions is FKM B (100%); followed by FAPERTA (94.1%), FATEK (82.4%), FAPET (80%), FEB (69.2%), FPIK (65%), Bank BNI (63.6%), FH (53.8%), FMIPA (45.5%), FKM A (33.3%), dan di FISIP (26.3%).

Abstract

AbstractIncreased population indirectly resulted in the development of urban areas physically and tends to alter green open spaces into built areas to meet the needs and improve services to the population. As a result there is an increase in air temperature, decrease in ground water quality and urban air quality, and high noise level. The existence of urban green open space arrangement can overcome the development as well as to overcome the ecological impact of various disruption of human activities on the natural process in the City of Manado. Then to realize the ecological balance in the Manado city, there is need of green open space development approach that refers to the area and the need of oxygen. This study aims to calculate the area of green open space needed by Manado City based on oxygen supply function. Data analysis of green open space requirement based on area according to Law Number 26 Year 2007 and based on oxygen requirement using Gerakis formula (1974) modified by Wisesa (1998). The results show the green open spaces needed in Manado City area of 2953.45 ha. In meeting the needs of green open spaces Manado City based on the oxygen provider function then everyone is required to plant 3 trees, on an area of 25 m2.Keywords: green open space, oxygen demand, Manado City.

ABSTRACT Capacity Of Karombasan River Channels  The Karombasan watershed has an area of 270 ha and river length of 3.058 m. The main river, Karombasan River, floods almost every year, possibly because the river channel is not able to accommodate the volume of the flow and thus causing a number of houses on the riverbank to be flooded. This flooding event is very disturbing to the locals. The purpose of this research is to analyze the river in location that often flood. Sampling and observation points were determined through purposive sampling methods at the points of frequent flooding. River capacity was analyzed using the Manning equation. Analysis of current river capacity from points 1 to 5 is 10,82 m³/s, 7,85 m³/s, 12,19 m³/s, 11,03 m³/s, and 5,32 m³/s, respectively.  Keywords : Watershed, flood, river capacity.

Abstract

ABSRACT The purpose of this study was to analyze the structure and composition of trees in the permanent plots of the Pinosian Natural Forest, South Bolaang Mongondow Regency. This research will be carried out in September-October 2018. Data is collected using the transect method. There are 5 transects within 500 m, the five transects are permanent transects that have been made by management (PT. Kawanua Kahuripan Pantera). In each transect, there are 5 observation plots measuring 20x20 m2. The distance between observation plots in the transect is 100 m. Observations were made on each individual tree in the observation plot, namely: identification of species and diameter measurements for individual trees that have a diameter of ≥20 cm. There are 25 tree species from 20 families, species with the highest INP are Palaquium gutta (40.52%), Magnolia obovata (18.61%), Macaranga sp (15.56%), and Pometia pinnata (13.39%). The tree structure shows that the distribution of the highest diameter class is the diameter class ≥40-50 cm (26%) and ≥50-60 cm (25%). Keywords: structure and composition, natural forest, Pinosian

ABSTRACTNOISE ANALYSIS GREEN OPEN SPACE IN MANADO CITYThis study aims to analyze the noise leve in several green open spaces in the city of Manado.This research was conducted in march 2020 in three locations, namely the UNSRAT field, theKONI field, and Jln.Piere Tendean-Ahmad Yani,Manado city, North Sulawesi. This study uses apurposive sampling method in determining the sampling point by means of measurements usinga sound level meter (SLM) and the data is processed by surfer 11 software. The results of thenoise level research for UNSRAT Field 40-70 dB(A), KONI Field 47-79 dB(A), and Jln.PiereTendean-Ahmad Yani 50-95 dB(A). From the results of the analysis of existing noise levels, itshows that the location with the highest noise level is Jln.Piere Tendean-Ahmad Yani which areincluded in the green open space area which are included in the green open space area whichonly reaches 71 dB(A) and 79 dB(A) the highest.Keywords: Noise, Green open space, and Manado City.
