This article aims to examine the flow of post-positivism philosophy in science learning in Indonesia as one of the challenges in achieving the competence of students' spiritual attitudes. The positivism paradigm holds that true knowledge must come or be based on experience, and that human reason is a requirement to consider whether experience is right or wrong according to the rules of logic and mathematical calculations, so that aspects of metaphysics that are not based on real experience are considered unclear and meaningless. The emergence of post-positivism is expected to provide a more meaningful understanding of scientific truth by shifting the concept of noumenon to phenomenon. The results show that: 1) The post-positivism paradigm is a school that wants to improve the weaknesses of positivism, which only relies on the ability to directly observe the object being observed, 2) In the learning process, core competencies for the attitude domain are not taught, but are integrated and developed. when learning aspects of knowledge and skills are carried out, 3) The practice of education in Indonesia, especially science learning, places spiritual attitude competence as a competence that is set aside which has an impact on the violation of spiritual values by students, 4) The current condition of education in Indonesia cannot be separated from the dominant influence of post-positivism which suppresses the portion for aspects that are metaphysical, including spiritual aspects.

Animal manure and water hyacinth become waste if not used. One of its uses is as raw material for biogas. The purpose of this study was to determine the effect of the type of manure on the formation of biogas from water hyacinth as seen from: 1) the rate of biogas formation, 2) the temperature of the slurry, 3) the pH of the slurry, and 4) the weight of the biogas produced. Research with Completely Randomized Design (CRD) consisted of five treatments (P); P1: cow dung + water hyacinth + water, P2: buffalo dung + water hyacinth + water, P3: goat dung + water hyacinth + water, P4: horse dung + water hyacinth + water, and P5: broiler chicken dung + water hyacinth + water . Each treatment was repeated 4 times to obtain 20 experimental units. The composition of the raw material mixture consists of 8 kg of water hyacinth chopped 2 cm + 3 kg of livestock manure + 2 liters of water. Parameters observed were: rate of gas formation, slurry pH, slurry temperature, and weight of biogas produced. The research was conducted at the Biology Education Laboratory, Faculty of Teacher Training and Education, Kapuas Sintang University. Data were analyzed by ANOVA at 5% significance level using SPSS 16.0 and BNT test if there was a significant difference between treatments. The results showed that the type of manure only had a significant effect on the weight of biogas formed, but had no significant effect on the rate of biogas formation, slurry pH, and slurry temperature. Thus the five types of manure can be used as a starter in the manufacture of biogas made from water hyacinth.

The teacher is a party that has great responsibility in achieving learning goals. One of the competencies that must be possessed by teachers is pedagogical competence. This research was conducted with the aim of uncovering the problems of teacher pedagogical competence in learning, as well as alternative solutions that can be done to overcome these problems. The method used in this research is literature analysis. The literature is a scientific article that discusses the problems of teacher pedagogical competence. The results of the study show that the problem of teacher pedagogic competence is the lack of the teacher's ability to plan, implement and evaluate the learning that is carried out. Planning, implementation and evaluation are related to all aspects of learning, be it objectives, materials, methods or evaluation. Alternative solutions that can be implemented are increasing teacher awareness of the importance of self-motivation, maximizing the function of the LPTK (Educational Personnel Providing Institution) in preparing competent teacher candidates and maximizing the function of teacher competency development programs.

This study aims to find out how the Index Card Match learning method influences the motivation and cognitive learning outcomes of students at SMP Negeri 4 Jonggat, Central Lombok Regency. Learning by using the Index Card Match learning method is expected to have students highly motivated in learning to obtain high learning outcomes as well. Through this application it can also make it easier for teachers to improve ways of thinking and increase student involvement in the teaching and learning process. The type of research used in this research is a quasi-experimental (quasi-experimental), this design has a control group, but it does not fully function to control the variables that affect the implementation of the experiment. The experimental class received treatment using the Index Card Match learning method, while the control class used the conventional method. To obtain the necessary data, this study used the t-test analysis technique. From the results of the study, based on the results of the hypothesis testing of the experimental class and the control class using the t-test, the tcount was 0.13 and the ttable was 2.12. This means that the tcount value is smaller than the ttable value or 0.13 <2.12. This shows that Ha is rejected and H0 is accepted, so there is an influence of the Index Card Match learning method on students' motivation and cognitive learning outcomes.
