Odonata is a group of insects that have medium to large in size and attractive color. These insects play an essential role as biological controllers and environmental bioindicators. This study aims to identify the types of dragonflies and damselfishes that found around Mahaka River, Hasanuddin University Teaching Forest. This research was held in October 2018. Observation and retrieval of dragonfly and damselfly data were carried out using the line transect and plot method. The samples were taken from 3 (three) zones with the distance between zones is 15 meters. The results showed that there were 12 types of dragonflies and damselflies from 3 familia found, namely Libellulidae (8 species), Chlorocyphidae (1 species), and Coenagrionidae (3 species). The highest number of dragonflies and damselfly is founded zone I and sequently found in zone II and zone III. The most frequency of appearance is found in the morning observations, and sequently found in the afternoon and evening observations.
This study aims to describe the implications of socio-economic change caused by tourism development and to explore the relationship between society and tourism from a sociological perspective. By using a qualitative approach with a case study research design, this study analyses data that was obtained through observation, documentation, and interviews. The participants involved were the local community living in Keciput village, the Keciput village staff members, the Tanjung Kelayang Beach tourism manager, and the Belitung Regency tourism office staff members. The study found that the tourism development of Keciput village had caused changes in the social and economic life of the local communities. In terms of social life, the emergence of tourism development had caused interactions to decrease. Previously, when the interactions among the people were still very intense, the economy of the community was also on the rise. However, ever since the tourism development took place, it has changed the people’s type of livelihood: where previously they had worked as fishermen, they are now working as transport services fishermen. The economic value of tourist activities is also classified into a higher category because the yield from the marine sources is very dependent on the season.
The propolis produced by honeybees as it is used a material for cosmetic and health industry fiberglass-constructed has high economy value. However, the effective methode for the propolis production has not been found. The objective of this research was to find out the effectiveness of four propolis traps variations on the propolis production of Apis mellifera honeybees. Materials used in this research were sixteen colony of Apis mellifera honeybees and propolis traps. The propolis production and the formed surface area on traps were collected from four trap treatments with four replications. The obtained data were analyzed by using Completely Random Design Analysis and Tukey Test. The most effective of propolis traps was that made of fiberglasses with hole direction same as frame direction (the average production of 2.03 g). The largest of propolis surface area was produced by propolis trap with hole direction same as frame direction (28.29 cm2). No corellation between the large of propolis survace (cm2) and propolis production (g) was observed. Keywords: honeybees, propolis traps, propolis production.
This study was intend to know and to identify bee forage in bee bread from honeybee in Teaching forest Hasanuddin University. Study method used in this study was survey method and identification of plant species were done in Plantation Industry Laboratory. There were 2 stage of the study i.e. collecting sample of bee bread from 4 species of honeybee (Apis cerana, Apis mellifera, Apis dorsata and Trigona sp) and identification of pollen in Plantation Industry Laboratory. Study results indicate that there were 20 pollen species i.e. banana (Musa paradisiaca), papaya (Carica papaya), Mango (Mangifera indica) puteri malu (Mimosa pudica), eggplant (Solanum tovarum), sangitan (Sambucus javanica), water apple (Syzgium aqueum), candlenut (Aleurites moluccana), jatropha (Jatropha curcas), euphorbia (Ephorbia milii), guava (Psidium guajava), Acacia (Acacia mangium), sugar palm (Arenga pinnata), nusa indah (Mussaenda pubescens), chili (Capsicum annum), puspa (Schima wallichii), coconut (Cocos nucifera), corn (Zea mays), jackfruit (Artocarpus heterophyllus), and Piperaceae. The highesr bee bread from 4 species of honeybee pollen was sugarpalm (Arenga pinnata) with percentage 15,08%. The lowest bee bread was guava (Psidium guajava) with percentage 0,09%. The most pollen collecting was Trigona sp with 10 plant species.
This study aims to determine the effectiveness of a portable honey thickener machine on several qualities of Trigona incisa bee honey. The research was conducted in Tamalanrea, Makassar City, South Sulawesi, and the process of testing the quality of honey was carried out at the Makassar Health Laboratory Center and PT. SUCOFINDO Makassar. The data analysis used is quantitative by calculating each of the observed variables, then the data obtained from each variable is compared with the SNI Standard 01-3545:2013. The variables observed in this study were Hydroxymethylfurfural (HMF), water content, reducing sugars (glucose and fructose), Sucrose, Acidity (ml NaOH 1 N/kg), water insoluble solids, and ash content. The results showed that the portable honey thickener machine was very effective in improving the quality of Trigona incisa honey after being added to the portable honey thickener machine when compared to SNI 2018, but when compared with the SNI 01-3545-2013 standard, some of the honey quality variables did not meet the standards. Honey quality standards are water content, reducing sugars (Glucose and Fructose), acidity, insoluble solids in water, and ash content, while those that meet SNI Standard 01-3545-2013 are reducing sugars Glucose and Sucrose.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
