Abstract

Tembelekan (Lantana camara L.) is an upright or semi-climbing shrub with a distinctive odor which is native to tropical and sub-tropical regions. This plant has many variations. The purpose of this study was to determine the morphological diversity of tembelekan using field observation methods in Buton, Central Buton, and South Buton Districts. The characterization process was carried out at the Integrated Laboratory of the Muhammadiyah University of Buton. The results of the observations were analyzed qualitatively by comparing the characters between individuals. The results showed that there were two groups of tembelekan in the Buton Islands, namely the orange and pink flowering groups. The orange flowering group has ovate leaf shape, coarse-hairy leaf surface, acute leaf apice, acuminate leaf base, serrate leaf margin, longer leaf size than the pink group, sepal is almost identical in size, orange flower group has fewer corolla than pink flower group. While the pink flowering group has deltoid leaf shape, coarse-hairy leaf surface, acuminate leaf tip, acuminate leaf base, serrated leaf margin, different sepal sizes and magenta flower color. It can be concluded that the two groups of tembelekan have differences in leaf shape, leaf tip, leaf length, sepal size, number and color of the corolla.

Abstract

Medaka fish (Oryzias javanicus) originating from Segara Anakan, Cilacap Regency has the potential as a bio-indicator of brackish water. The study of the physiological character of this species has not been done before, so that there needs to be basic information for domestication. The purpose of this study was to determine changes in protease, amylase and lipase digestive activity of medaka fish from Segara Anakan at different body sizes and salinity. The study was conducted by survey method. A sample of 567 medaka fish taken from three locations with different salinities (10 ± 1, 15 ± 1 and 20 ± 1 ppt) at the time of sampling, were used in this study. Medaka fish is grouped into three different sizes, namely (1) 0.063±0.01g (small), (2) 0.153±0.03 g (medium), and (3) 0.287±0.03 g (large). Measurements of enzyme activity were carried out by spectrophotometric methods. The results showed that body size and salinity were significantly different (P<0.05) on protease, amylase and lipase digestive activity of medaka fish. Large medaka fish shows higher digestive enzyme activity compared to the small body size in each salinity. However, amylase and lipase show same activity between different body sizes at 15±1 ppt. The higher the salinity, the lower the activity of protease, amylase and lipase. However, the salinity of 10±1-20±1 ppt shows the same amylase activity (small and medium size) and lipase (small size). Conclusion from the results of this study is the protease, amylase and lipase digestive activity of medaka fish that originating from Segara Anakan, Cilacap has been increased with increasing body size and decreasing environmental salinity. The results of this study are expected to contribute to the enrichment of fish biology, especially medaka fish.

Abstract

The anthracnose caused by the Colletotrichum acutatum Simmonds fungus is one of the limiting factors for the production of red chilli. The occurrence of anthracnose determined by the success of pathogenesis by C. acutatum. Also, red chilli which is resistant to anthracnose has a higher ascorbic acid content than vulnerable red chili. This paper presents scientific information about the ability to grow three C.acutatum isolates (Kulonprogo, Temanggung, and Pandeglang) on a culture medium given ascorbic acid. The three C. acutatum isolates have high pathogenicity. The results showed that administration of ascorbic acid in the culture medium only affected the dry weight of mycelium and did not affect the diameter length of the colony of C. acutatum.

Abstract

The Invasive Aliens Species (IAS) has become an ecologically distinctive threat to the conservation area which is a biodiversity sanctuary, the Baturraden Botanical Garden (KRB). This research aims to know the IAS that can affect the biodiversity of vegetation in KRB. The KRB is divided into 10 plots, and then observes the existing IAS vegetation along with environmental factors such as temperature, humidity, soil pH and canopy cover. Introductory process information and conservation strategic recommendations are obtained through literature studies and interviews with resource persons. The data then analyzed using the Importance Value Index (INP), the Shannon-Winner Diversity Index, the individual spatial distribution pattern of a species at each growth rate is calculated based on the Morishita Index. The results showed that the IAS introduction process began in 1952 through the utilization of Protected Forest (HL) and Limited Production Forest (HPT) in KRB; The vegetation community structure in the KRB is dominated by spikes (saplings), seedlings, trees and poles. There were 13 IAS species consisting of 9 families; Seedling and saplings Calliandra houstoniana var. calothyrsus (Meissner) Barneby and Agathis dammara (Lamb).
