Authors. 2018. Genetic variability, heritability, correlation, and path analysis in tomato (Solanum lycopersicum) undershading condition. Biodiversitas 19: 1527-1531. Information on genetic variability, heritability and character association betweenquantitative characters with yield are crucial in crop improvement. Eighteen genotypes of tomato were evaluated to study thequantitative genetic of yield and various yield attributing character under shading condition at Pasir Kuda Station, Bogor AgricultureUniversity, West Java, Indonesia from August 2016 until January 2017. The result showed that plant height, dichotomous height, fruitweight, fruit length, fruit diameter, number of fruit per plant, and the fruit set had broad genetic variability and high heritability.Characters with broad genetic variability and high heritability can be used as sources in shading tolerance tomato improvement. Fruitweight and fruit number per plant had significant positive correlation coefficient and direct positive effect on fruit yield per plant. It is,therefore, recommended that

Indonesia has one of the fastest growing, injecting drugs user-driven, human immunodeficiency virus (HIV) epidemics in Asia. Coverage of needle and syringe programs (NSPs), opioid substitution therapy (OST), and antiretroviral treatment (ART) is increasing, but is still low, whereas professional training in addiction medicine is not yet established. Urgent development and scaling-up of professional capacity in comprehensive, evidence-based addiction medicine is needed. In this article the results of the first step is presented, being the training needs assessment (TNA) and the process of further developing a national evidence- and competence-based addiction medicine curriculum in Indonesia.

Environmental education is a cornerstone of many wildlife conservation programs, and measuring the impact of such education initiatives is imperative for evaluating their effectiveness in achieving conservation goals. For over 15 years, the Gunung Palung Orangutan Conservation Program (GPOCP) has been working to protect wild Bornean orangutans Pongo pygmaeus wurmbii living in and around Gunung Palung National Park in West Kalimantan, Indonesia. In 2015, we carried out a series of six Environmental Education Expeditions to communities in the remote districts surrounding the Park, engaging 1519 elementary (n = 770) and junior/senior high school (n = 749) students across 24 schools. Before and after engaging with our environmental education activities students were given surveys to assess their knowledge about and attitudes toward orangutans. We found that our educational activities led to 13.6-40.4% increases in student knowledge about orangutans and substantial shifts toward more positive attitudes about conservation, but that many students do not believe that they personally can make a difference. Empowerment may be a key need to link wildlife education to environmental action.

Objective: To determine the effectiveness effectivity of mouthwash from Aloe vera juice after scaling treatment on patient with gingivitis. Material and Methods: This was an experimental research using pretest and posttest design with control group. The number of samples of 30 people selected using sampling method quota sampling. Samples were divided into two groups: test (n = 15 skeletons with Aloe vera juice) and control (n = 15 just scaling). Gingival inflammation is measured using a gingival index according to Loe and Sillness on the first day before scaling treatment and 7th day after scaling. Data analysis was conducted using SPSS version 20. Independent-samples t-test and paired-samples t-test were used for data analysis. The statistical test performed has a significance level of 0.05 (p = 0.05) and confidence level of 95% (α = 0,05). Results: There was a significant decrease in the mean score of the gingival index in the control group (1.1 to 0.5) and the test group (1.2 to 0.4) significantly (p<0.05). Conclusion: The use of mouthwash from Aloe vera juice can decrease gingival inflammation, which can be seen from the gingival index score on all test subjects. The decrease in gingival index in the test group using the Aloe vera juice was greater than that of the control group, which was not given the mouthwash.

Background. Periodontitis can be treated by regenerating periodontal tissue using a bone graft. Several natural materials such as chitosan and minerals such as hydroxyapatite can be developed to increase periodontal tissue regeneration. Chitosan has a high potential in healing wounds. Hydroxyapatite has excellent properties such as biocompatibility, osteoconductive, osteoinductive, and osteogenesis, making it an ideal material for soft and hard tissue regeneration. Chitosan and hydroxyapatite can be obtained from the shells of crustaceans, such as crabs shells (Portunus pelagicus). Objective. To assess the effectiveness of the combination of chitosan gel and hydroxyapatite powder as a bone graft on periodontal tissue regeneration in experimental animals. Periodontal tissue regeneration was assessed by expressing inflammatory cytokine gene indicators IL-1 and BMP-2. Methods. Experimental laboratory research and clinical trials with posttest only control group design. Twenty-seven Wistar rats were divided into three groups. Then the femoral bone defect was made, the positive control group was given placebo gel, the positive control group was given BATAN hydroxyapatite, and the test group was given a combination of chitosan gel and hydroxyapatite crab shells. Wistar rats were sacrificed on days 7, 14, and 21, and the femur bone was then taken for immunohistochemical analysis to determine the levels of IL-1 and BMP-2. The Kolmogorov–Smirnov test, Levene test, and one-way ANOVA analyzed the data. Results. On days 7, 14, and 21, the expression levels of IL-1 and BMP2 were significantly different between the three groups. The group added with chitosan gel and crab shell HA showed a faster decrease in IL-1 expression than the control group. BMP-2 expression increased in the test group compared to the control group. Conclusion. The combination of chitosan gel and hydroxyapatite inhibited the production of proinflammatory cytokines and increased the production of BMP-2.
