Abstract

Indonesia has a tropical climate is rich in flora diversity. Many medicinal plants, including the Kepel (Stelechocarpus burahol), are herbal medicines. Kepel Fruit (Stelechocarpus burahol) contains secondary metabolites of alkaloids, flavonoids, polyphenols, saponins, triterpenoids and quinones. Some of these compounds have anti-fertility properties. Antifertility compounds are compounds that can prevent fertility by interfering with several normal reproductive mechanisms, both in men and women. This study aims to analyze the effectiveness of Kepel fruit extract on the growth and development of secondary spermatocytes in mice (Mouse muscle). This research uses true experiments and Posttest-Only Control with a quantitative approach. The samples used for this research design, both experimental and controlled, were taken randomly. Testing the significance of the treatment effect uses parametric statistics, namely the One-Way ANOVA test at a significance level of 5% (α = 0.05). Then, if there are differences, continue with the LSD further test (Least Significant Difference) at a significance level of 5% (α = 0.05). This research design used a Randomized Block Design (RAK) with a total sample of 32 mice (Mouse muscle) with 8 repetitions and 3 treatment groups. The growth and development of secondary spermatocytes in mice are determined by counting the number of secondary spermatocytes in the seminiferous tubules of mouse testicular incisions. The results of the one-way Anova test show that the calculated F is 6.41, and the value is sig. (P.Value) of 0.002, these results suggest  P.Value (0.002) < the α value (0.05), which means that the number of secondary spermatocytes is significantly different in each group so that this study can conclude that the administration of Kepel fruit extract (Stelechocarpus burahol) can significantly reduce the number of growth and development of mouse secondary spermatocytes (Mouse muscle ).

Abstract

Beetles exhibit unique shapes and color variations and play important ecological roles in the environment. Suranadi Nature Tourism Park (TWA Suranadi), a nature-based tourism area, has the potential presence of beautiful beetles. This study aims to examine the diversity of beautiful beetles in TWA Suranadi to support its tourism appeal. Sampling was conducted in May 2024 by surveying predetermined paths. The beetles collected were identified using identification books, relevant articles, and taxonomic name verification through websites. Thirteen species were identified, belonging to six families (Cerambycidae; Chrysomelidae, Erotylidae, Eucnemidae, Hydrophilidae, Scarabaeidae). The Chrysomelidae and Scarabaeidae families were species-rich and exhibited diverse shapes and colors. Beetles found along the forest edge path showed greater diversity (H’=2.3842) compared to the other two paths, namely the water path (H’=2.2893) and the middle path (H’=1.9804). The diversity (H’) of beautiful beetles in TWA Suranadi was 2.3532.

Abstract

Sumbawa society is rich in culture, especially in traditional medicine. People use materials from the surrounding environment, including plants and animals, as active ingredients for medicine. Newborn babies and toddlers are susceptible to blockage of the respiratory tract with mucus. In babies, it is usually caused by an imperfect suction process, while in toddlers, it is caused by bacteria or viruses. The Samawa people use a mixture of cuttlefish (Sepia sp.) and eucalyptus oil as a medicine that effectively removes mucus from the body. The active ingredient in cuttlefish has an unpleasant odour and cannot be stored for long. When they need cuttlefish, people must look for them in markets or traders on the coast. Of course, this takes time to use. The ointment production innovation has many advantages, including practicality, no fishy smell, ease of obtaining, and ease of storage for the long term. Using the natural active ingredient lemongrass, essential oil adds aromatherapy and provides warmth to the chests of babies and toddlers. Natural active and gel-based ingredients are safe to use without side effects. The ointment was tested for active ingredient content using GCMS and organoleptic tests for gel stability, spreadability (homogeneity), pH, and skin irritation. Based on the description above, it can be concluded that the ointment product is made from an anti-skin irritation gel base, pH 7, and gel spreadability of 5.5 cm. The active substance comes from cuttlefish Sepia sp. by inhibiting the COX-2 enzyme and reducing the production of prostaglandin E2 (PGE2), an essential inflammatory mediator in the pathogenesis of asthma and bronchitis. The simple production process means that the price of the ointment is within people's purchasing power.

Abstract

Pickled betung bamboo shoots (Dendrocalamus asper) are a traditionally fermented product and can potentially be a source of probiotics. Pickled bamboo shoots contain good microorganisms, namely LAB, which are bacteria that contribute to the food sector for natural fermentation. Fermentation of bamboo shoots produces antioxidant compounds at an optimum temperature range. The research aims to understand the optimum temperature for the amount of LAB and antioxidant activity in pickled betung bamboo shoots. This research is a laboratory experiment with 3 treatments, namely 100 grams of bamboo shoots fermented with pickled bamboo shoots at a temperature of 15℃ (K1), a temperature of 37℃ (K2), and a temperature of 40℃ (K3). The three treatments were incubated for 72 hours with 4 repetitions. The research stages included processing pickled bamboo shoots, isolating bacteria using the dilution series-pour plate method, and antioxidant testing using the DPPH method. The number of LAB is calculated using the Quebec Colony Counter. Data analysis used Anova and Duncan's test. The results obtained include that temperature influences the amount of BAL in pickled bamboo shoots with a value of p=0.016. The number of LAB at a temperature of 150C was 59.50, at a temperature of 37 129.74, and a temperature of 40 107.57. Temperature also affects antioxidant activity. The average values at temperatures of 15.37, 40℃ are 30.60%, 25.241%, and 16.8782% (% inhibition), 36.3655, 41.6775, 51.0757 (IC50). The optimum temperature for the number of BAL pickled bamboo shoots is 37°C, and the optimum temperature for the number of antioxidants is 15°C.

Abstract

Hepatitis B is transmitted through blood or body fluids contaminated with the virus from Hepatitis B sufferers (carriers). The factors that cause a person to contract Hepatitis B are sexual intercourse, blood contact, placental contact from the mother to the baby, and saliva. The incubation period for Hepatitis B Virus (HBV) ranges from 30 - 180 days with an average of 60 - 90 days. HBV can be detected 30 - 60 days after infection and persists for a certain period. Thus, the behaviour of infectious diseases can be observed and described using mathematical modelling. Mathematical modelling is a field of mathematics that represents and explains physical systems or problems that occur in the real world and are solved in mathematical statements. The mathematical model used to overcome uncertainty in variable values ​​is a stochastic model. These causal factors are not directly observed and form a Markov chain. The model that can be used for the uncertainty of an event is the Hidden Markov Model. The Hidden Markov Model (MHM) is a type of stochastic modelling that does not recognize the factors that trigger the problem being modelled. The Poisson Hidden Markov model is used to model Hepatitis B disease. Hepatitis B disease data is a series of observations that experience overdispersion and depend on the trigger of Hepatitis B disease, which is assumed not to be observed directly and forms a Markov chain. The aim to be achieved in this research is to model Hepatitis B disease at the Medan Haji Hospital using the Poisson Hidden Markov model and to find parameter estimates using the Expectation Maximization Algorithm. This type of research uses quantitative research methods. The conclusions that can be drawn based on the results and previous discussions are as follows: the method for determining the average number of patients in patient B can use the PHMM (Poisson Hidden Markov Model) method with the EiM (Expectation-Maximization Algorithm) algorithm, the best model for the number of Hepatitis B patients in Haji Hospital at this hospital is the model with three hidden cases with the parameter estimation value. The average number of Hepatitis B patients is 0.0324 in 1 month, and the average predicted results obtained by the hidden condition model 3 align with the original conditions in the previous months.

Abstract

Sanitation is an important health initiative that protects the cleanliness of the environment and its users. Basic sanitary facilities include clean water, wastewater treatment, drainage channels, and waste management. This research aims to provide an overview and information regarding the availability of basic sanitation facilities in a settlement. The research was conducted in Mataram District, West Nusa Tenggara. The research method used in this research is a descriptive qualitative method. The research focuses on identifying fundamental sanitation aspects, which include design and construction, waste management, wastewater management, and drainage systems. Direct observation, structured interviews, and in-depth interviews gathered data. According to the research findings, Mataram District's clean water supply comes from PDAM and drilled wells; waste management is not optimal because waste sorting and processing are not yet available, wastewater treatment is still done on-site in septic tanks in each house, and some wastewater comes from washing activities. While bathing drains into the gutter, the residents' yards have a gutter-based drainage system. The participation of all stakeholders, including the local administration and the local community, is necessary to optimize the sanitation system in Mataram District. The implementation of regulations and the provision of infrastructure are essential for the support of drainage and waste management systems. To preserve the cleanliness of wastewater channels, the community can take an active role in processing refuse, beginning at the household level and cleaning the gutters.

Abstract

Student achievement is an indicator of learning success that indicates the extent to which a student has acquired the skills and knowledge set forth by their educational program. Understanding students' learning styles plays a significant role in determining learning success. One of the efforts to optimize student achievement is facilitating learning activities that align with students' learning styles. Students are no longer preoccupied with understanding their learning styles but are focused on deepening the material. This study aims to describe the learning style profiles of students, and students and lecturers in the learning process can follow up on the results. This study uses a survey research method with a questionnaire instrument containing 54 statements. A learning styles questionnaire prepared based on the opinion of De Poter & Hernacki is used as a data collection tool. Learning styles are identified as visual learning style, auditorial learning style, and kinesthetic learning style. The questionnaire was distributed to students in semesters 2, 4, 6, and 8, totaling 51 students. The data analysis technique used is a descriptive analysis of the questionnaire results. The questionnaire results show that 36% of students have visual and kinesthetic learning styles, 14% have auditory, and 14% are inconsistent. This inconsistency may suggest a balanced learning style, where students do not rely heavily on one learning mode but rather integrate multiple styles depending on the context. Therefore, the Science Education Study Program lecturers should implement a learning model that can facilitate visual and kinesthetic styles, even though the subjects taught are theoretical. Incorporating a variety of teaching methods, such as visual aids, hands-on activities, and auditory discussions, can accommodate the diverse learning preferences of students, leading to a more inclusive and effective learning environment.

Abstract

Indonesia is one of the countries with a very high level of biodiversity. West Kalimantan is one of the provinces with the highest level of biodiversity in Indonesia. One form of biodiversity found in West Kalimantan's forests is bintangur (Calophyllum spp.). The very high diversity of bintangur species is fascinating to be utilized as a source of learning biology, especially in the material of biodiversity and their interactions and roles. This study aimed to analyze the potential of bintangur diversity in West Kalimantan as a biology learning resource on the material of biodiversity and their interactions and roles in senior high school. This research uses the qualitative method. This research consists of two stages. The first stage is a literature review to find information related to bintangur species in West Kalimantan. In contrast, the second stage is an analysis of learning resource requirements based on the results of the literature review that has been carried out. The results of the literature review stage show that there are 27 species of bintangur in West Kalimantan, as well as their classification, main characteristics, habitats, and values to the environment and other organisms. The literature review stage results are then continued to the learning resources analysis. Six requirements must be met for learning resources: clarity of the potential availability of objects and problems raised, suitability for learning objectives, clarity of targets and their designation, clarity of information disclosed, clarity of exploration guidelines, and clarity of the results to be achieved. The analysis of learning resource requirements that have been carried out shows that the diversity of bintangur species in West Kalimantan meets the requirements of learning resources so that it can be utilized as a biology learning resource on the material of biodiversity and their interactions and roles in senior high school.

Abstract

Creative thinking is a habit of sharp thinking with intuition, moving the imagination, revealing new possibilities, uncovering unique ideas, and inspiring unexpected ideas. Based on fluency, flexibility, and originality, this research aims to describe students' creative thinking abilities regarding energy material in class VII life systems at SMP Negeri 1 Tapa. This research type is descriptive qualitative research. The instrument used is a 10-number essay test whose validity has been tested. The sample used in this research was 30 students. The results of research on creative thinking abilities on energy materials in living systems are in the fluency aspect of 55.83% in the enough creative category, the flexibility aspect of 67.5% in the creative category, and the originality aspect of 52.5% in the enough creative category. This shows that the low ability to think creatively is due to students' need to understand the creative thinking ability test and students' unfamiliarity with creative thinking. Students are expected to be able to practice working on questions that can hone creative thinking skills and can use the results of this research as a reference for further research related to creative thinking skills.

Abstract

Earthworms are a group of animals that live in soil and have a segmented body, bilaterally symmetrical, and covered by a transparent cuticle, which protects from physical and chemical disturbances. One of the factors that influences the growth of earthworms is the availability of food substances in the media where they live. Research on the analysis of the increase in the number and total weight of earthworms (Lumbricus rubellus) due to the provision of fruit waste in feed has been carried out in 2023. This research aims to analyse the increase in the number and total weight of earthworms due to the application of fruit waste to the media where earthworms live. Research data was analysed using variance analysis. In this study, the results were obtained: (1) fruit waste pulp (papaya and banana) added to feed had a significant effect on increasing the number of earthworms, (2) fruit waste pulp added to the feed can increase the total weight of earthworms, (3) Giving 2 liters of fruit waste to the feed results in a higher number and total weight of earthworms than other levels of fruit waste pulp.
