Research on active learning that emphasises question formulation activities has received less attention. This study was conducted to address the said gap identified in the literature by testing the thinking empowerment by questioning (TEQ) strategy on the level of conceptual understanding (CK) and critical thinking (CT) of students in Biology subjects. We used a pre-test-post-test non-equivalent control group design with a sample of junior high school students (n = 176). Participants were divided into three groups, namely (1) the TEQ group, 61 students; (2) PS (problem-solving) group, 60 students; and (3) the CS (conventional strategy) group, 55 students. We also considered the effect of school type (public and religious) on student performance in each treatment group and identified a potential correlation between CK and CT. Statistical results showed that TEQ had a more effective and significant effect on students' CK and CT than in the two control groups. However, we identified no difference between students in public and religious schools in each treatment group. In addition, this study also found a strong correlation between CK and CT through the implementation of TEQ. Finally, TEQ is an effective active learning strategy that promotes students' critical thinking in science content and is equally effective when administered to public and religious schools.

Tempe chips is one snack that is popular with all groups. During this time the process of slicing tempe chips is still using the conventional method using a hand knife. This resulted in the ineffectiveness of the process of slicing the tempe stem which is the basic ingredient of tempe chips with a relatively long duration of ± 30 slices/minute. Besides that, ± 10% -15% slices have varied thicknesses and are relatively thick (3mm), which causes crispy tempe chips. Due to constraints in the process of cutting tempeh, SMEs can only produce 10kg / day and cannot meet market needs that reach twice the current SME production. In addition, because the cutting process is done manually, it requires a large amount of power, a long time, not hygienic and prone to work accidents. To overcome the problems of partners, the partner SMEs will be assisted through the design of tempe chip slicing machines. The method of carrying out this activity is designing, manufacturing, assembly, testing of machines, handover of machines, training in operation and maintenance of machines, and periodic monitoring. Based on the results of implementation in the SME tempe chips manufacturer, the tempe chip slicing machine really helped solve the problem of the tempe chips SME producer. This can be seen from the practicality of the slicing process which requires a relatively fast time of 60 slices / minute so that employees are not easily exhausted. It also improves the quality of tempe chips, where uniform thickness of tempe chips is 2mm and is more hygienic because the machine material is made of foodgrade stainless steel standards. Some of these advantages have an impact on production capacity that has doubled from 10kg / day to 20 kg / day.

This study was intended to display the role of eco-school program (Adiwiyata) towards environtmental literacy (EL) of high school students by analyzing, (a) EL of students in Adiwiyata and non-Adiwiyata high schools, and (b) EL of students in Grade X and XI, Adiwiya and non-Adiwiyata high schools in Malang-East Java, Indonesia. The survey involved 275 students. The respondents were from four state high school i.e. SMAN 1, SMAN 3, SMAN 4, and SMAN 7. Data were taken via MSELS questionnaire that was modified and filled online. Aspects of EL include ecological knowledge, environmental affect, cognitive skills, and behavior. The results of multivariate analysis showed that the level of students’ EL was significantly influenced by school type and grade. However, the interaction both of them had no significant effect on their EL. Univariate results on school type factor informed that significant differences occured in all aspects of EL, where the lower identified level of students in Adiwiyata schools compared to Non-Adiwiyata was only in the environmental affect. On the other hand, the significant influence of grade level only occurred in cognitive skills aspect. Broadly speaking, all data analyzes concluded that the application of the Adiwiyata program was able to bring a positive impact on the level of students’ EL. There was also a tendency that the higher the student's grade, the better their EL level.

Oleh karena itu, diperlukan alat yang dapat menyiram kecambah secara otomatis untuk menjaga suhu akurat pada suhu 30 C. Jadi, pada proyek akhir ini dibuat sebuah sistem penyiram tauge otomatis menggunakan mikrokontroler arduino uno sebagai pengendali motor pada saat penyiraman tauge. Selain itu, sumber energi matahari (Fotovoltaik) dan angin (Turbin angin) digunakan sebagi produksi listrik dari sumber energi alternatif pada sistem penyiram tauge. Namun, perubahan cuaca yang tidak menentu membuat turbin angin skalakecil yang terhubung ke jaringan dan sistem fotovoltaik tidak diragukan lagi akan mempengaruhi masalah kualitas daya. Dalam artikel ini pengukuran daya yang dihasilkan oleh sistem tenaga hybrid (tenaga angin dan tenaga matahri) untuk menentukan sejauh mana error yang dihasilkan antara perhitungan dengan hasil pengukuran. Variable pengukurannya adalah tegangan, arus, intensitas cahaya, dan kecepatan angin. Pengujian sistem tenaga hybrid yaitu tenaga matahari (fotovoltaik) mampu menghasilkan total daya rata-rata 18.19 watt dengan nilai error 7.1 %, sedangkan pada tenaga angin (turbin angin) mampu menghasilkan total tegangan rata-rata 32,5 V dengan arus 0,216A dan nilai error 37,8 pada percepatan angin rata-rata 3 meter/sekon.

This research is quantitative survey research that aims to identify the level of scientific reasoning ability of Biology prospective teachers, as well as to determine the effect of the semester on scientific reasoning abilities. A total of 80 Biology prospective teachers were involved in this study, consisting of 18 (semester 2), 29 (semester 4), and 33 (semester 6). LCSTR is an instrument used to measure scientific reasoning ability. The data were analyzed descriptively to classify the level of scientific reasoning ability, while to determine the effect of the semester on scientific reasoning ability, it was analyzed univariately using SPSS 22 at a significance level of 5%. The results of this study indicate that the scientific reasoning ability of Biology prospective teachers is dominated by concrete and transitional reasoning, and semesters have no effect on scientific reasoning abilities. These results also indicate that Biology prospective teachers have the same level of scientific reasoning ability. Furthermore, these results can be concluded that the scientific reasoning ability of Biology prospective teacher students has a low level, which is at the initial level (concrete reasoning). Then for the further work, it is described a little at the conclusion of this article.
