This study aimed to examine the implementation of the School Literacy Movement (SLM) by observing its impacts toward the scientific literacy, characters, and HOTS of Grade VII Junior High School (JHS) students in Pekanbaru within the context of K-13. The survey was conducted with 45 natural science teachers on the basis that they have integrated K-13 into their teaching and learning. The data of SLM implementation was obtained from the teacher by means of questionnaires and observation which was conducted in science classes in three JHS in pollution and global warming topics. The results showed that 49.13% of activities were successfully implemented by SLM. The results showed that students’ scientific literacy in the three schools were 69.5%, 76.3%, and 75.2%. Meanwhile, the character values have reached 80.6%, 76.4%, 72.9%, and students’ HOTS values were 73.0%, 72.5%, and 73.3%. Based on the survey, it can be concluded that although the school has pioneered SLM, the strengthening of scientific literacy, characters, and HOTS has not been executed by all teachers who implement K-13 due to various obstacles need new policies to assess the execution of the SLM program by the local education department.
This paper describes the role of the insect, which is essential for human survival, but still people are not familiar with widely even some people consider insects no meaning or viewed from the downside. Diversity of epiphytes and insects in the canopy of palm oil plantations in North Sumatra assessed by field observations at five locations, namely, Bukit Sentang, Padang Mandarsyah, Ajamu, Sijambu-jambu, and Aek Pancur. Data were analyzed using qualitative and quantitative. Based on the results obtained by analysis of the biological diversity of insects that affect the quality and quantity of farm products. In natural ecosystems, generally there has been a stable population of pests and their natural enemies so that the presence of insect pests in cropping is no longer harmful. Thereby, the conditions need to be developed so as to reduce the use of pesticides to control pests in field crops, especially in export-oriented and has high economic value.

The 2013 curriculum requires teachers to integrate higher-order thinking skills. One of them is creative thinking. Mind map integration in Problem Based Learning (PBL) is thought to be able to assist students in improving creative thinking. This study aims to determine the effect of increasing creative thinking through the integration of mind maps in PBL on eighth grade students of SMPN 25 Pekanbaru. This type of research is quasi-experimental. The research population was class VIII SMPN 25 Pekanbaru. The research sample consisted of class VIII.1 as the experimental class and class VIII.2 as the control class. Data in the form of pretest and posttest. N-gain analysis was conducted to see the increase in student scores and MANOVA was used to examine the effect of mind maps in PBL on students creative thinking abilities. The average value of creative thinking is better in the experimental class which is 78.08 in the digestive system material with N-gain relatively close to high, namely 0.68 while in the control class only 54.88 is sufficient category. The MANOVA test also shows that there is an effect of mind maps in PBL on the creative thinking ability of class VIII SMPN 25 Pekanbaru with a significance value of 0.000 <0.05. This shows that the application of mind map integration to PBL is able to improve the creative thinking skills of SMP Negeri 25 Pekanbaru students.
The research was conducted to investigate the substitution effect of dietary salted marine by-catches and fish viscera meal mixtures for conventional fishmeal on physicochemical and sensory quality of Indonesian river catfish. Four experimental diets containing 34% crude protein and 3.20 kcal g−1 digestible energy were formulated. A control diet (FM) contains 54% fishmeal and no salted marine bycatch - fish viscera mixture (SMBFVM). In the other diets, the fishmeal was reduced and proportionally replaced with SMBFVM, 50% (SMBFVM-50), 75% (SMBFVM-75) and 100% (SMBFVM-100). A commercial diet (CD) containing 32 % crude protein and 2,94 kcal g−1 digestible energy was used as the reference. Feeding trial was performed with 1500 fish (4.79±0.38 g in weight) which was distributed in 2x2x1.5 m triplicate net cages, and the fish was fed the experimental diets at satiation twice daily at 07:00 AM and 05:00 PM for 8 weeks. There was no substitution effect of fishmeal by SMBFVM on the survival rate of the fish (P>0.05). Substitution of fishmeal by SMBFVM in the diet up to 75% (SMBFVM-75) increased weight gain, specific growth rate, food efficiency ratio, protein efficiency ratio and protein retention (p<0,05) better than control diet; and complete substitution of fishmeal with SMBFVM (SMBFVM-100) gave similar growth performance to control diet (P>0.05). Total replacement of fishmeal with SMBFVM in the diets also gave comparable body fish proximate and amino acid profile to control diet. Compared to CD, fish fed SMBFVM diets had similar growth performance, body proximate, and amino acid profile. The SMBFVM, therefore, could completely replace conventional fishmeal in the diet for Indonesian river catfish without negative effects on fish growth, body proximate, and amino acid profile.
Plants are the main medicinal source that exists around the world, due to the content of bioactive compounds such as flavonoids, alkaloids, saponins, polyphenols, tannins, terpenoids, and essential oils. These bioactive compounds have antimicrobial activity. The purpose of this study was to analyze the antibacterial activity of a combination extracts of Sumatran wild mango (M. sumatrana, and M. foetida var. Batu), R. tuberosa L. and Leucobryum sp. against bacteria that cause gangrene wounds in diabetics. Preparation of plant extraction is carried out by the method of maceration using 70% alcohol. Testing of antibacterial activity using the disc paper method 6 mm in diameter at an extract concentration of 10% with seven treatments (P1-P7). The test results obtained the largest inhibitory zone diameter against Staphyococcus aureus ATCC 6538 and S. epidermidis ATCC 12228 both shown in combination II extracts at P7 treatment (2:3:1 ratio), 9.04±1.42 mm and 8.85±0.21 mm, respectively. The results of the inhibitory zone resulting from the combination extract test included criteria of resistance to Staphylococcus. In the positive control, the diameter of the chloramphenicol inhibition zone against S. aureus belongs to the sensitive category, but to S. epidermidis it belongs to the resistant category. Combination of methanol extract from wild mango, R. tuberosa L and Leucobryum sp. has the opportunity as the candidate for natural-based antibiotics to replace synthetic antibiotics.
