Abstract

A complete solar eclipse is a rare event, and we know very little about how other species, including our closest living relatives the primates, react to these events. We observed orangutans on the island of Borneo, Indonesia during a rare astronomical event of a total solar eclipse. Captive orangutans in Nyarumenteng rehabilitation center, Central Kalimantan were observed to document their reaction to this unexpected environmental event. Based on this study that was conducted in 2016, the dramatical behavior demonstrated in the time of the total solar eclipse, and the general response differed between before and after the event. During the total solar eclipse, flanged males tended to increase their social behavior compared to the unflanged males. These findings indicate that the total solar eclipse resulted in an environmental stressor for these captive orangutans.

Abstract

The role of the community in the use of medicinal plants is very important to encourage the development of natural resources in the surrounding environment and improve the degree of public health. Medicinal plants that have been widely researched and are often used by the people of Indonesia since a long time ago, can be an alternative treatment or support conventional treatment therapies. The purpose of this study was to determine changes in society in relation to the use of medicinal plants, document the diversity of medicinal plants and how to use medicinal plants by the community, and obtain a list of plant species based on the use value of disease categories. Data collection is done by open interviews, participatory observation, focus group discussions (FGD). Data were analyzed descriptively to describe the changes that occurred in the community before and after the existence of medicinal plants, inventorying the composition of medicinal plant species and how to use them. Quantitative analysis is done by calculating the Local User's Value Index (LUVI). The changes that occur are people using medicinal plants for cultivation, curing diseases and maintaining health. There are 44 plant species from 40 genera and 26 plant tribes used to cure 46 diseases. Asteraceae is a plant species with the highest number of species that are used as medicinal ingredients. Based on the calculation of the value of LUVI, Dayak onions are medicinal plants that have the highest score, which is 6%. Then followed by bay leaves 4.65% and sidaguri 4.55%. Ten common diseases that occur in the community are diarrhea, gout, cholesterol, high blood pressure, gastritis, rheumatism, asthma migraine, stroke, fever. Utilization of medicinal plants carried out by the community that is, by making processed products such as instant simplicia powder, dried simplicia, herbal medicine and tea bags. There is a change in the use of medicinal plants from previously not using medicinal plants and currently using medicinal plants to cure a disease and maintain health. The change occurred because of the existence of the non-governmental organization Aliksa as a facilitator and local leader who managed and assisted the cultivation and utilization program of medicinal plants. Common diseases that occur in the people of Hurip Jaya village are diarrhea, gout, cholesterol, high blood pressure, gastritis, rheumatism, asthma migraine, stroke, fever. Utilization of medicinal plants used as processed products such as instant simplicia powder, dried simplicia, herbal medicine and tea bags.

Abstract

Plants contain compounds that can be considered as antimicrobials. The community of Turi Putih Village have used plants that have medicinal properties to treat certain diseases, especially those caused by bacteria. For this reason, it is necessary to conduct research on the use of medicinal plants and antibacterial tests from plants originating from Turi Putih Village. The purpose of this study was to determine the diversity of medicinal plants, plant parts used, preparation and use of medicinal plants by the local community, as well as the antibacterial potential of medicinal plants that have High score of Use Value (UV) and Fidelity Level (FL) ​​to treat those diseases. Data was collected by using semi-structural interviews and respondents were chosen by purposive sampling. To analyze the data, we adopted qualitative and quantitative ethnobotanical technique. Qualitative, namely descriptive methods to make an inventory of the composition of medicinal plants and preparation and use by the community, and quantitative to see the most commonly used and most preferred species ethnomedicinal plant species for treating certain ailments. . Based on interviews with respondents, the community uses 44 species of medicinal plants, 40 genus that belong to 26 plant families to treat 19 diseases caused by bacteria. Based on UV and FL scores, mint leaves (Mentha piperita) and kencur leaves (Kaempferia galanga) had the highest scores. The results showed that mint leaves and kencur leaves have antibacterial activity by forming an inhibition zone against Staphylococcus aureus and Escherichia coli. In this study, extract from leaf of K. galanga appeared to be more potent than that of leaf of M. piperita, and produced consistent level of inhibition of bacterial growth. Since it was revealed that the leaves extract of Kaempferia galanga has the ability to inhibit the growth of Staphylococcus aureus – food – poisoning organism, hence, it would be interesting to investigate the potentially of this plant for possible application in foods to promote safety.

Abstract

Kaliage Besar Island is one of the islands in Seribu Islands National Park, DKI Jakarta. Located in the Management Section of Kelapa Island Region I National Park. The island with the allotment of the use rights of the private island which is used as a public tourist and resort. Kaliage Besar Island still has the potential for highly productive coral reef resources. Currently, the coral reefs of Kaliage Besar Island has suffered damage caused by anthropogenic activities and natural factors. This research used Underwater Photo Transect/UPT method were analyzed using CPCe 4.1. software (Coral Point Count with Excel extension). Data collection was carried out at one research point with a depth of 3 m and a transect length of 20 m with 3 data collection times (10 m intervals between transects). The measurement physico-chemical parameters results was shown that water quality in Kaliage Besar Island was still within tolerance limits for coral life. The percentage of live coral cover was in a bad category with a low value 6,46%. Composition of hard coral genusis consists of 6 family, 7 genus, and 119 individuals. The most dominant genus is Porites with submassive and massive growth form. The index value of diversity shows a low category (0,42). The dominance index value showed a high category (0,84). Uniformity and mortality index value showed a low category (0,22 and 0,28).

Abstract

Local chicken has an important role as a source of animal protein producing eggs and meat. Local chicken has the advantage of being able to adapt to hot weather and be more resistant to disease. However, there are still weaknesses, namely relatively slow growth and relatively low egg production. Therefore, one way to overcome these weaknesses is by holding selection and crossing. Local chickens used for crossing in this study were sentul, kampung and kedu chicken. In connection with the growth of chickens that are slow and low in productivity of local chickens, it is necessary to examine the factors that influence growth and productivity. The hormones that have an effect on growth are GH (Growth Hormone), so that the characteristics of the gene of growth in local chickens from the cross can be known.The purpose of this study was to detect the characteristics of the Growth Hormone gene in local chickens resulting from Three Breed Crosses . The research material used in this study was forty local chickens produced by cross-sentul, kampung and kedu chicken. To find out GH gene polymorphism is by PCR-RFLP with cutting enzyme EcoRV.The results of the GH gene study in sentul, kampung and keducrossed chickens are polymorphic and are in the Hardy-Weinberg equilibrium state. Kampung chicken cross population was polymorphic for GH|EcoRV loci and the GG genotype was predominant in this population. G allele frequency in kampung,kedu and sentul chicken cross population is higher than the A allele. The highest genetic diversity was observed at kampung,kedu and sentul chicken cross and the heterozygosity value was lowcategory.
