Abstract

The traditional sea-picking ceremony is a ritual carried out by the community as a form of gratitude for the abundance of sustenance provided by God, as well as for asking the safety of fishermen. Besides aiming for blessings and safety, the traditional sea picking ceremony also has an important role as a means of communication for fishermen and maintaining harmony among religious communities, therefore this traditional sea picking ceremony must be held once every year. The purpose of this study was to observe the nature and processing of plants and animals at sea picking ceremony and to find out the Use Value (UV) of plants, animals and the natural environment used. Sampling of informants was done by Purposive Sampling and Snowball Sampling; data obtained using semistructured interviews with open ended question types. The results showed there were 66 species from 37 plant families and 3 species from two animal families. While the Use Value (UV) analysis indicates that there were 12 plant species and one animal species that have a high Use Value (UV) which is 1, it shows that the species is most widely used in traditional sea picking ceremonies. Generally, it needs more efforts for further conservation.

Abstract

Chitinolytic bacteria are bacteria that have chitinolytic activity, which is able to hydrolysis the composition of chitin which composes many fungal cell walls. Chitinolytic bacteria are currently more widely used because of their ability as a biological control agent to the pathogenic fungi especially in horticultural and plantation crops. This research was conducted with the aim of obtaining isolates of chitinolytic bacteria that were able to inhibit the growth of plant pathogenic fungi in Vitro on chitin agar media. Fusarium oxysporum, Sclerotium rolfsii, and Rhizoctonia solanii are used in the inhibition test of chitinolytic bacteria. Bacteria were isolated and screened from the soil of Bukit Dua Belas National Park and Oil Palm Plantations in Jambi using 0.3% chitin agar media. The results showed that two of 10 bacterial isolates were able to produce inhibition zones to the growth of hyphae of pathogenic fungi on potato dextrose agar (PDA) media. TB04-13 isolate was able to produce the largest inhibition in F. oxysporum and R. solanii about 42% and 42.05% respectively, while TB04-15 isolate produced the biggest inhibition in S. Rolfsii ranged to 25.50%. Based on the chitinolytic index (CI) values, isolates TB04-13 and TB04-15 produced CI values ​​of 1.60 and 0.63, respectively. The morphological characteristics and Gram staining of both TB04-13 and TB04-15 chitinolytic isolates are included in rod-shaped and Gram-positive bacteria. Both of these isolates can be used as antifungal-producing candidates for plant pathogenic fungi in Indonesia.

Abstract

Slender walking catfish (Clarias nieuhofii) is a consumption fish that has a fairly high economical value. Local market prices can reach IRD 50.000-70.000/kg. People love this fish because of the delicious taste of the meat, which very different from the aquaculture catfish. Until now the production relies only on natural catches and there have been no cultivation efforts. But in recent years these out catfish are increasingly difficult to find in nature. The conversion of land into plantation areas caused the loss of the fish's original habitat. Based on community information, the habitat of this fish is found in Pasir Putih Village, Silangkitang District, Labuhan Batu Selatan Regency, and Bandar Tinggi Village, Bilah Hulu District, Labuhanbatu Regency, Indonesia. Differences in habitat conditions are known to affect fish growth patterns, including C. nieuhofii. This research aims to determine the pattern of the growth of the slender walking catfish in these different habitat conditions. Exploratory methods were used in this research and observation stations were determined through purposive sampling. Fish sampling was done using a fishing rod. The samples of fish captured were measured by the total length and weight. The results of the research show that the pattern of fish growth in Pasir Putih Village is negative allometric (W = 0.6944, b = 0.2463 and R2 = 0.9468) and in Bandar Tinggi Village shows negative allometric (W = 10.207, b = - 129.56, and R2 = 0.9711).

Abstract

In 21st century learning, critical thinking skills are the main choice that must be mastered by students. This study aims to determine the effectiveness of local wisdom-based science teaching materials in improving junior high school students’ critical thinking skills. Most science teachers still apply teacher-centered learning, so students tend to be passive. This type of research is quasi-experimental with a pretest-posttest control group design. The study was conducted in the even semester of the 2019/2020 school year. The subjects of the research were grade VII students. Data collection techniques and instruments in the form of tests that include indicators of critical thinking skills. Data analysis used homogeneity test, Kolmogorov Smirnov normality test, independent sample t-test, and n-gain score. The results of the independent sample t-test are sig. (2-tailed) = 0,000<sig. α = 0.05. Students’ critical thinking skills in the experimental class were higher (N-gain score = 39.09%) than in the control class (N-gain score = 12.03%). Based on the study results, it can be concluded that there is a significant influence on the application of local wisdom-based teaching materials in improving the critical thinking skills of middle school students in the moderate category.

Abstract

Research on indirect organogenesis of cucumber apple (Cucumis sp.) was conducted from March to May 2020. This study aims to find the best combination between Benzyl Amino Purine (BAP) and Naphthalene Acetic Acid (NAA) on the growth of cucumber apple (Cucumis) sp.) on Gamborg media (B5) by organogenesis. The callus used came fromcucumber seeds explants with a concentration of NAA 2,0 mg/l + BAP 0,2 mg/l using Murashige and Skoog media. The research method used is an experimental method with nonparametric statistics with 24 treatments repeated three times and analyzed descriptively using the Kruskal Wallis test. The results showed that the best treatment of cucumber apple shoots was the combination of NAA and BAP, namely the B4N2 treatment (2,5 ppm BAP + 0,20 ppm NAA) with shoot height (0,45 cm). At a single concentration, a concentration of 1 ppm BAP was able to provide a faster effect on shoot formation time, namely at 24 days after initiation (hsi) and the best response to shooting height (0,5cm).
