TL;DR: The Duncan multi-rage test result showed that the higher values for all measured parameters were obtained at the dosage of 27.5 mg kg -1 of feed, and it was concluded that the optimum dosage of papain enzyme for keureling fish was 27.
Abstract: The objective of present study was to determine the optimum level of papain in the diet of keureling fish ( Tor tambra ). The complete random design was utilized in this study. Six levels of papain dosage were tested in triplicates, i.e. 0 (control); 17.5 mg kg -1 , 20.0 mg kg -1 , 22.5 mg kg -1 , 25.0 mg kg -1 and 27.5 mg kg -1 of feed. The experimental fish were fed the experimental diet two times a day at 8 AM and 5 PM at feeding level of 5% body weight for 90 days. The Anova test result showed that papain enzyme gave a significant effect on the weight gain, daily growth rate, specific growth rate, survival rate, feed conversion ratio and feed efficiency (P<0.05). The Duncan multi-rage test result showed that the higher values for all measured parameters were obtained at the dosage of 27.5 mg kg -1 . Therefore, it is concluded that the optimum dosage of papain enzyme for keureling fish was 27.5 mg kg -1 of feed. How to Cite Muchlisin, Z. A., Afrido, F., Murda, T., Fadli, N., Muhammadar, A.

TL;DR: In this article, a qualitative method with ethnobotanical approach was applied in this study, which revealed that 9 kinds of the traditional rituals that have been predominantly undertaken by the Baduy community in the management of swidden farming system.
Abstract: On the basis of recent studies in many places of developing countries it has been revealed that the practices of conservation of biodiversity has strongly determined by traditional ecological knowledge, and beliefs or cosmos. The aim of the study namely to elucidate; (1) some traditional rituals in the swidden management system of the Baduy community; (2) various plants that have been used for performing some rituals in the swidden management system of the Baduy community; and (3) some functions of various plants that have been used in the rituals of the swidden management system of the Baduy community. A qualitative method with ethnobotanical approach was applied in this study. The result of study shows that 9 kinds of the traditional rituals that have been predominantly undertaken by the Baduy community in the management of swidden farming system. At least 50 plant species representing 28 families have been used for those performing traditional rituals. The main function of plants in the rituals is considered as the symbolic meaning and rational function. The result of study has been considered very important that the traditional ecological knowledge and beliefs must be considered to conserve biological diversity.

TL;DR: In this article, a quasi experimental study was conducted at two grade ten classes at a state high school in Bandung, Indonesia, where data were collected using a questionnaire called Constructivist Learning Environment Survey (CLES) before and after the laboratory activities.
Abstract: Laboratory activities and constructivism are two notions that have been playing significant roles in science education. Despite common beliefs about the importance of laboratory activities, reviews reported inconsistent results about the effectiveness of laboratory activities. Since laboratory activities can be expensive and take more time, there is an effort to introduce virtual laboratory activities. This study aims at exploring the learning environment created by a virtual laboratory and a real laboratory. A quasi experimental study was conducted at two grade ten classes at a state high school in Bandung, Indonesia. Data were collected using a questionnaire called Constructivist Learning Environment Survey (CLES) before and after the laboratory activities. The results show that both types of laboratories can create constructivist learning environments. Each type of laboratory activity, however, may be stronger in improving certain aspects compared to the other. While a virtual laboratory is stronger in improving critical voice and personal relevance, real laboratory activities promote aspects of personal relevance, uncertainty and student negotiation. This study suggests that instead of setting one type of laboratory against the other, lessons and follow up studies should focus on how to combine both types of laboratories to support better learning.

TL;DR: It can be concluded that supplementation of turmeric powder improve the chemical quality of Japanese quail eggs (Coturnix japonica), so it is good for the development of quail embryos as well as for consumption.
Abstract: The experiment was conducted to determine the effect of turmeric powder supplementation to the age of sexual maturity, physical, and chemical quality of the first Japanese quail’s (Coturnix japonica) egg. Forty five quails were assigned into a completely randomized design with three treatments (levels of turmeric powder, i.e., 0; 54; and 108 mg/quail/day) and each treatment used 15 quails. Turmeric powder supplementation was conducted before sexual maturity. Feed and drinking water provided ad libitum. Observed egg is an egg that was first produced. Parameters measured were the age of sexual maturity, feed intake, body weight, physical qualities which include: weight of egg, long axis, short axis, weight and thickness of shell, yolk index, Haugh unit, egg shell index. Whereas the observed chemical quality were cholesterol, HDL, LDL, protein, vitamin B12, vitamin A in eggs and egg shell calcium levels. The results showed that administration of turmeric powder can accelerate the age of maturity, increasing the levels of protein, HDL, vitamin A and B12 in eggs, decreasing the cholesterol and LDL content in eggs, but did not affect feed intake, physical quality of eggs and egg shell calcium levels. Based on the results of this study, it can be concluded that supplementation of turmeric powder improve the chemical quality of Japanese quail eggs (Coturnix japonica), so it is good for the development of quail embryos as well as for consumption.

TL;DR: In this article, the authors provided significant ethnobotanical information on medicinal plants in Karangwangi Village of Cianjur District, West Java, Indonesia, where they aimed to identify plants collected for medical purposes by local people as well as to document the local names, uses, preparation, and location of these plants.
Abstract: The knowledge and usage of plant as medicinal remedy by current generation are not as extensive as previous; therefore, many rural communities with restricted modern medical access still rely on traditional medicine. This paper provides significant ethnobotanical information on medicinal plants in Karangwangi Village of Cianjur District, West Java Indonesia. This study aimed to identify plants collected for medical purposes by the local people as well as to document the local names, uses, preparation, and location of these plants. Ethno botanical data was recorded by opting people participation and key informant approach involving semi-structured interviews, group discussions and filling of questionnaires. The results showed a total of 114 medicinal plants belonging to 50 families were identified. Zingiberaceae was the most-frequently cited (nine species), followed by Asteraceae, Euphorbiaceae, and Fabaceae (seven species each). The most-used plant parts were leaves (51.8%), followed by stems (22.9%) and the most common preparations were decoction, poultice and squeezed. Most of the plants were obtained from the house-yard and total of 30 medicinal uses were recorded. The ethnobotanical result documented in this study showed that this area is rich in medicinal plants and these plants are still commonly used for medicinal purposes among the people in their daily lives. Ethnobotanical heritage should be preserved, however, there is a gradual loss of traditional knowledge about these plants in new generation. Further, the findings can be used as baseline information for further scientific investigation for analyzing phytochemical, pharmaceutical and other biological activities for future drug discovery.
