Abstract

Myristica fragrans Houtt. is a spice plant that is used as a spice in the kitchen, food preservatives, beverages, perfumes, cosmetics and soaps. The large use of nutmeg plants results in high industrial demand for nutmeg but the availability of nutmeg is minimal because generative propagation using seeds is still constrained because the structure of the seed coat is hard so that germination takes up to 8 weeks. Dormancy breaking can be done with chemical compounds such as the use of KN03 (potassium nitrate). This study aims to determine the effect of soaking time of nutmeg using KN03 solution and determine the efficient time of soaking nutmeg using KN03 solution on germination. This study used a completely randomized design (CRD) which consisted of 5 levels of immersion time, namely without immersion KN03, immersion 12 hours, 24 hours, 36 hours and 48 hours. Parameters observed were germination percentage and germination time. Data were analyzed using ANOVA at 5% level and DMRT follow-up test. The results showed that the duration of soaking nutmeg seeds using KN03 had a significant effect on the percentage of germination and germination time. The treatment of soaking nutmeg seeds with 2% KNO3 for 24 hours was an efficient treatment for nutmeg seed germination with a germination percentage of 88.3% and germination time of 23.7 days.

Abstract

The need for active and innovative learning models in the 21st century encourages teachers to use appropriate learning models to achieve learning objectives. PjBL is a learning model that organizes classes in a project. The purpose of this study was to re-analyze research on project-based learning models (PjBL) in biology learning. This study uses the method of meta-analysis by reviewing a number of research results related to the research theme. The samples taken from this study were 10 articles with national and international standards. Based on the results of the analysis, the overall average effect size is 0.936. This shows that overall the project-based learning model has a high effect, so that it can be used as an alternative learning model that is effectively applied in biology learning.

Abstract

One of the economic values of plants is that they can be used as medicine. Indonesian people since ancient times have used plants as traditional medicine. This knowledge has been passed down from generation to generation and there are differences between regions. This is due to differences in customs and experiences of people who use traditional medicine. Based on this, it is necessary to carry out an inventory or record of plants that act as medicines so that they can be properly documented. The purpose of this study was to obtain data on the types of plants used as traditional medicine by the local community. This research was conducted in West Pussui Village, Luwo District, Kab. Polewali Mandar, West Sulawesi. The method used is explorative which is descriptive qualitative in nature. The data collection technique used Participatory Rural Appraisal (PRA), through in-depth interviews covering the types of plants that can be used as medicine, their uses and how to mix the plants used. In addition to interviews, direct observation was also carried out to see the conditions at the research location. The technique of selecting respondents was done by snowball sampling. Data from interviews and observations were then presented in the form of pictures and tables and then analyzed using descriptive qualitative. The results showed that the people of the Mandar tribe used kirinyuh, guava, soursop, jatropha banana, cocoa duck, papaya, black turmeric, moringa, coconut, secang wood, bitter melon, meniran, lime, purslane and breadfruit as traditional medicine to treat various kinds of diseases. The part of the plant that is most widely used to treat diseases is the leaf with a percentage of 50%.

Abstract

Developments in the 21st century in the field of education seek students to be able to think critically and be aware of environmental conditions. Phrases Think global, act local are sentences related to awareness of environmental conditions. The real form of the phrase think globally (think globally) is to develop a product in the form of an encyclopedia that contains information about biology, while the real form of the phrase act locally (act locally) is in the form of research conducted. The encyclopedia is a comprehensive collection of information on the morphology of the myrtaceae family in the collection of kebun raya banua. The purpose of this study is related to describing practicality. Development research model to improve and enhance previous products. Research development using Tessmer's formative evaluation design. Individual test (one to one evaluation), and small group test (small group evaluation). The personality test subjects (one to one evaluation) were three students who had taken plant morphology courses related to content practicality data, the small group evaluation subjects were four students who had taken plant morphology courses related to practical expectations data.

Abstract

The rapid growth of Indonesia's population has resulted in increasing national energy needs which require alternative energy. Alternative energy that can be made is briquettes by producing biomass waste. The purpose of this study was to obtain the quality of charcoal briquettes from kolang forth skin waste using a mixture of starch and sago flour as an adhesive. In this study there were tests for water content, ash content, heat and density. The completely randomized design (CRD) method was used in this study, with 5 treatments and 3 replications. Obtained research results using kolang forth shell waste can be used to make charcoal briquettes. Average water content and ash content comply with SNI 1-6235-2000. The best water content value was found in treatment E (0% starch adhesive : 30% sago adhesive) which was 3.8%. The best ash content value was found in treatment A (30% starch adhesive: 0% sago adhesive) which was 5.87%. The calorific value did not meet SNI but met Japanese standards and the best treatment results were found in treatment C (15% starch adhesive: 15% sago flour) which was 5,470 cal/gr. Meanwhile, the density values ​​do not meet SNI but meet British standards for all treatments. The best density value was found in treatment A (starch adhesive 30: sago adhesive 0) which was 0.84%.

Abstract

This study aims to determine the effect of the group investigation cooperative learning model assisted by audio visual aids on the motivation and learning outcomes of class X SMAN 3 Pekanbaru. This research was conducted in class X of SMAN 3 Pekanbaru in the 2022/2023 Academic Year. The research design used was quasi-experimental, using the matching only pretest posttest control design. The research sample was class X students with 36 experimental and 36 control classes respectively taken by Simple Random Sampling. Data collection was carried out through pretest, posttest and observation sheets. Based on the research results obtained for the learning motivation questionnaire value in the control class was 2.48 with a percentage value of 62.10% in the medium category, while for the learning motivation questionnaire value in the experimental class given the treatment of cooperative learning model group investigation type of 2,97 with a percentage value of 74.47% in the high category. Based on these categories, there was an increase in learning motivation in the experimental class which was given treatment with the group investigation type cooperative learning model assisted by audio-visual aids. For the mean N-Gain in the control class 0.29 (low), while in the experimental class 0.52 (moderate). On the results of the N-Gain t-test the value of Sig. (2-tailed) Equal variances not assumed on the output of the Independent sample test value is 0.000 <0.05 then reject Ho which means that there is a significant difference between the N-Gain control class which is given treatment with conventional learning and the experimental class which is given treatment with cooperative learning model with the type of group investigation assisted by audio visual which shows an increase in learning outcomes. Thus learning using the cooperative learning model type group investigation assisted by audio visual aids in virus material affects the motivation and learning outcomes of class X SMAN 3 Pekanbaru in the 2022/2023 Academic Year.
