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

Abstract

ABSTRACTThe objectives of this study were to analyze the weight loss, texture and colorchanges of lettuce during cold storage and determine the packaging that can be usedto store lettuce with a longer shelf life. The results of this study, lettuce using LDPEand PP type packaging at a temperature of 8.14 oC gave the best results for 9 daysof storage. Lettuce stored at 8.14 oC using LDPE and PP packages gave the smallestpercentage weight loss results, namely 4.48% and 1.03%. The hardness valuepacked with LDPE plastic at the base is 5.51 N, the middle part is 1.18 N, and thehardness value packed with PP plastic at the base is 4.23 N, the middle is 1.32 N.The last day gave the results of the hardness value packed with LDPE plastic at thebase of 8.56 N, the middle part of 1.31 N and the type of PP plastic packaging whichhad a hardness value at the base of 8.81 N, the middle part of 1.87 N with a physicalappearance still fresh and hard and the color changes to yellowish green on theleaves. LDPE and PP plastic packaging gives good results which can be used forstorage of lettuce with a longer shelf life.Keywords: Lettuce, PVC and LDPE packaging, PP

Abstract

ABSTRACTMinimally processing of fresh carrots with vacuum packaging stored in lowtemperatures. The research objective is to assessing the quality of texture, change in weight,color, and moisture content and to determining the shelf life of minimally processed carrotsin vacuum packaging. Carrots were washed, then peeled, cut into pieces with a thickness of0.6 cm, after that rinse with water and chlorine. Then packaged according to treatment(vacuum and without vacuum) with a weight of 100 g each, after that it is stored in arefrigerator that has a temperature of 6 oC - 12 oC. The results showed that the initial watercontent of the sliced carrots day 0 has an average of 89.13%, after the 24 day for vacuumpackaging has an average of 91.13% and the packaging without vacuum has an average of90.87%. The average value of weight loss in vacuum packaging is 0.52%, and packagingwithout vacuum is 1.23%. Average value of texture on the vacuum package was 16.73 N, andthe final value of texture 12.96 N and the average texture value on the packaging withoutvacuum is 0: 17.29 N. After the 24th day is 14.85 N. Color changes on vacuum packs andwithout vacuum start on the 15th day until the 24th day from orange to orange yellow.Keywords: carrot, minimalyl processing, vacuum packaging, quality, low temperature.

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 The drying of the nutmeg using a tent-type solar dryer has been carried out in order to determine the drying characteristics of the nutmeg flesh and to determine the drying efficiency. The results showed that the drying process of the material to reach a moisture content of 12-14% took 19 hours with the average solar radiation intensity on days 1, 2, and 3 being 429.06 W/m2, 446.16 W/m2, and 560.13 W/m2. This intensity resulted in temperature changes for the material temperature and room temperature of the dryer on days 1, 2 and 3 which ranged from respectively (38.5 oC and 32.88 oC), (41.5 oC and 32.88 oC), and (43.5 oC and 32.46 oC). The average humidity of the air inside and outside the dryer on days 1, 2, and 3 are (80.62% and 83.19%), (76.34% and 79.50%), and (81.19% and 81.41%). The drying rate of the nutmeg flesh for days 1, 2, and 3 varied with an initial moisture content of 85.26% (bb). The results of the calculation of drying efficiency on day 1, 2, and 3 were 28.09%, 9.03% and 2.33%, respectively. Key words: Drying characteristics, radiation intensity, drying efficiency.

Abstract

ABSTRACT The handling of Kepok bananas within inter-island transportation in Biaro, SITARO Regency is still traditionaly, therefore Kepok bananas suffer mechanical damage such as bruises, scratches, and broken wounds. Good handling steps are needed in the transportation process so that the product can arrive in the hands of consumers in good quality conditions. This study aims to determine a good packaging that is able to withstand pressure and friction during the transportation of Kepok banana fruit from Biaro to Manado. Research using the Experimental Method with Descriptive Analysis. The packaging consisting of  plastic sacks, cardboard packaging and wooden box packaging. Kepok bananas are packaged according to available packaging and transported by ship from Biaro Harbor to the Ferry Port in Munte then by land transportation to Manado. The results showed that the highest mechanical damage during transportation was found in Kepok bananas packed with plastic sacks at 41.84%, followed by Kepok bananas packed with cardboard with a damage value of 36.56%. Meanwhile, the lowest level of mechanical damage was in bananas packed with wooden boxes at 32.59%. Keywords: Postharvest Handling, Transportation, Packaging

Abstract

ABSTRACT Wildlife is a form of natural wealth and biodiversity of natural resources. Habitat destruction and human activities, factors that influence the decline in wildlife populations, are evident in Mt. Ambang Nature Reserve. The purpose of this study was to determine the richness of species, level of encounter, and abundance of wild species by using camera traps in the Mt. Ambang Nature Reserve. Data analysis is based on species, the number of photos, the number of individuals and the number of active days of cameras. The results shows that there were 5 wildlife species i.e. Ailurops ursinus (Phalangeridae), Gallus gallus (Phasianidae), Macaca nigra (Cercopithecidae), Macrogalidia musschenbroekii (Viverridae), Sus celebensis (Suidae). The encounter rate (ER) is dominated by M. nigra (ER 0.70 photos/day) and followed by G. gallus, M. musschenbroekii, S. celebensis, A. ursinus (ER 0.10, 0.06, 0.03, 0.01 photos/day, consecutively). The wildlife species with the highest abudance is M. nigra (KR 63,4). It is followed by G. gallus, M. musschenbroekii, A. ursinus, and S. celebensis (KR 19.5%, 9.7%, 4.8%, 2.4%, consecutively). Keywords: wildlife, camera traps, level of encounter, abundance
