Abstract

ABSTRACTAVIFAUNA POTENCY FOR DEVELOPING BIRDWACTHING ECOTOURISM IN THE VILLAGE OF ECOTOURISM BAHOIThe research aimed to study diversity, distribution, and avifauna potency for birdwacthing ecotourism in the mangrove vegetation of Bahoi village, west of Likupang, North Minahasa. The research was conducted from June to September 2015. The purposive method was used to collect data. Observations were made at 36 points determined based on bird preferences. From that observations it was found 47 bird spesies, belonging to 25 families. Among all the species, 65.9% is categorized as resident, 23.4% as endemik of Sulawesi, and 10.6% as migratory. Based on the government regulation (PP No. 7, 1999), there are 12 protected birds spesies within the resident and Sulawesian endemic species. The value of diversity in this mangrove was 3.24 or higher than Shannon-Wiener criteria. Index of eveness was 0.84 or higher than Magguran criteria. Based on all the values obtained, two birdwatching lines for ecotourism were proposed.Keywords: avifauna, bird diversity, ecotourism, birdwacthing.

Abstract

ABSTRACTThis research is aimed to study the phenology of angsana trees in the urban areas of Manado city. Sam Ratulangi street is divided into five observing segments with relatively the same number of trees at about 129-131 at each segment giving a total of 651 trees. The phenology observed at each tree including leaf, flower, and fruit phenomenon. The diameter of each tree are measured. Trees were then greuped into five categories:<10, 10-<20, 20-<30, 30-<40 and ≥40 cm. The results shows that angsana trees in Sam Ratulangi street had diameter of about 3.4-50.5 cm.The highest accumulation at trees was at last fourth categories ranging at 132-185 trunks. The phenology of leaves which dominate the entire segments on Sam Ratulangi street are green leaves at 89.9%of the 651 trees.The shoot phenology was performed by 11-20 trees (1.7-3.1%) and the flowering phenomena were found in 17-20 trees (2.6-3.8%). The flowering phenomena was mostly found at segment 1 (zero point) and becoming less and less toward the upper segments (Citraland intersection). The fruiting phenology shows and an opposite trend. The new flowering phenology are found on trees in three categories at medium diameters (10-40 cm) while the phenology of fruiting are found on trees with large diameters (>20 cm).

Abstract

Abstract Land cover type is a factor that needs to be taken into account in an effort to rehabilitate a watershed as it can affect planting activities, resulting in varying use of working time.  Nevertheless, technical instructions applied to reforestation are still general. Therefore there is a need for a standard working time in reforestation (planting) as a guideline in determining policies in planting activities. This research was conducted in Bantik Village, Bolaang Timur District, Bolaang Mongondow Regency during one month. to analyze the work performance of planting on several types of land cover. The study used repetitive timing for data collection method which is then analyzed and furtherly tested with ANOVA. The results showed that land cover has a significant effect on work performance, the work performance of planting on young shrub land cover has the highest achievement of 16 seeds per hour followed by an old shrub of 15 seeds per hour and bush of 12 seeds per hour. Keywords: Work performance, plantation, land cover

AbstractThis research aims to study the structure and composition of forest tree vegetation in the protected forests of Mount Mahawu and Mount Masarang. Line Method was used to study the changes in tree distribution based on the topography and elevation. Plots measuring 20 x 20 m2 are made following topographic lines (mountain slopes). The results show that the structure and composition of the dominant trees in the Mahawu Protection Forest are different from that of the Masarang Protection Forest. The dominant species in the Mahawu Protection Forest are Diospyros celebica, followed by Ficus septica and Anthocephalus chinensis; while in the Masarang Protected Forest Artocarpus sp. followed by Ficus septica and Lansium sp.Keywords: forest tree structure, forest tree composition, Mount Mahawu, Mount Masarang, protected forest

Abstract

ABSTRACT Tahuna is located on Sangihe Island which has a wealth of unique species of birds. Along the coast of Tahuna Bay there are three types of land cover namely the built area, coastal forest and mangrove forest, the difference in the existence of this area is followed by variations in the diversity of bird species, because found different types of birds from each type of habitat that made the observation point. The study was conducted at six locations using the point count method. This study aims to compare the diversity of bird species and communities in the built area, coastal forests and mangrove forests in Tahuna Bay. Data obtained from observations in the field will be analyzed with simple descriptive statistics and then displayed in tables and figures. Data analysis was performed to obtain species richness, diversity indexes, community similarities, and abundance and population. Data analysis was performed to evaluate species richness and density, biodiversity index, and community similarity. The results showed that in Tahuna Bay there were 27 species of birds from 15 families with the highest species richness in the Mangrove area which was low in human activity (15 species, 10 families) and the lowest wealth in the built area that was utilized for shops (5 species, 5 families) . The bird with the highest density in the Bay of Tahuan area is the Erasia Church Bird (Passer montanus) (K = 7.67 D / ha). Teluk Tahuna has a moderate species diversity index (H '= 2.28) with an evenness index from each observation point (E = 0.69). Natural areas (coastal forests and mangroves) have the highest community similarity value of (IS = 73%). Compared to the built area, which has the lowest community similarity value of (IS = 25%).

Abstract

ABSTRACT POTENTIAL OF BIRDWATCHING ECOWISATA IN KETAMA ADVENTURE PARK MINAHASA This research aims to study bird diversity and the effects of vegetation cover said dicersity, as well as perception of Touliang Oki villagers about Birdwatching Ecotourism in Ketama Adventure Park, Minahasa. The study was conducted in August to September 2019 in Ketama Adventure Park and Touliang Oki Village, Tondano District, Minahasa Regency. Observation were made using a point count method for bird diversity and vegetation cover, and rapid assessment and interviews for community perceptions. A total of 13 points were observed spread over 4 land cover types. This study found 48 bird species from 22 families. Shannon-Wiener Indeks calculation for diversity scores resulted in a value of 2.58, which falls into the medium category. Vegetation and habitat types were compared to each other to obtain similarity indices. This resulted in 6 pairwise comparisons, were 5 pairs had a high similarty index (> 50 %) while 1 pair had a low similarity indeks (< 50 %). Based on interviews Touliang Oki Villangers supports the existence of Birdwatching Ecotourism activities in Ketama Adventure Park as an economic driver. Keywords : Ecotourism, Birdwatching, Ketama Adventure Park.

Abstract

ABSTRACT Increasing population growth has resulted in the development of cities as centers of activity demanded to accommodate community needs. The physical development of cities is often inseparable from changing the natural landscape and spatial planning resulting in a decrease in carrying capacity and environmental services. Land limitations and spatial planning are increasingly becoming important steps to improve environmental quality, one of its efforts is by building green open spaces. Based on the results of previous studies, this study aims to determine the possibility of increasing the need for an area of green open space in the city of Manado in 2020. The results showed that the need for Green Open Space (RTH) in the city of Manado experienced an increase in 2020 to 9,364.82 ha. Keywords: green open space, oxygen demand, Manado City
