The present study was an attempt to investigate the effect of Problem-Based Learning (PBL), Predict, Observe, Explain (POE), and the combination of both (PBLPOE) on students' critical thinking skills and scientific attitudes in Biology. A pretest-posttest nonequivalent control group design was employed in this study and 132 tenth-grade students from Bengkulu, Indonesia was involved. This study was carried out from February to June 2018. An essay test was administered to assess the participants' critical thinking skills, and a checklist and an interview guideline were used to observe the students' scientific attitudes. The results of the ANCOVA analysis showed that PBL, POE, and PBLPOE had an effect on the students' critical thinking skills and scientific attitudes in Biology with p-value<0.005. The results of the LSD test indicated that PBLPOE was not significantly different from PBL, but differed considerably from POE and conventional in improving students' critical thinking. Also, LSD test on the students' scientific attitudes showed that PBLPOE differed significantly from PBL, POE, and conventional in enhancing students' scientific attitudes. The highest post-test score was observed in the PBLPOE classroom. Therefore, PBLPOE can be used to improve students' performance in Biology.

This study aimed to investigate the potential effects of problem-based learning (PBL), predict observe explain (POE), and PBLPOE on students' problem-solving skills and self-efficacy in Biology. This research is based on various facts that problem-solving skills and selfefficacy of Indonesian students in biology subjects are still low.Research Methods: This quasi-experiment employed a pretest-posttest non-equivalent control group design. One hundred and thirty-two (132) tenth graders (aged 15 to 17) from Bengkulu, Indonesia, participated in this study. The participants were homogenous concerning academic abilities. Data were collected using an essay test and observation sheets.

This study aimed to investigate the correlation between critical thinking skills and academic achievement in Biology through the implementation of problem-based learning-predict observe explain (PBLPOE) learning model. The study was conducted from February to June 2018 in the even academic year of 2017/2018. A correlational design was employed in this study. The participants consisted of tenth graders from Public Senior High School (SMAN) Number 5 in Bengkulu, Indonesia. The students’ critical thinking skills and academic achievement were measured using essay tests. The result of the regression analysis showed that there was a significant correlation between students’ critical thinking skills and academic achievement in biology, where Y=7.383 + 0.500x. The regression equation suggests that students’ academic achievement may improve as the students’ critical thinking increases. Therefore, it is advisable for the educator to promote critical thinking skills in the classroom in order to improve students’ academic achievement by, for example, implementing PBLPOE learning model.

Self-efficacy is the student's belief in the ability to perform necessary tasks or actions to achieve a particular outcome. Self-efficacy can influence students' feelings, ways of thinking, motivations, academic achievements, and social behaviors. The higher self-efficacy that students have, the higher the achievement and ability students may get. The purpose of this research was to know the self-efficacy of State Senior High School students in Bengkulu City, Indonesia toward Biology Lesson. Measurement of self-efficacy refers to 3 aspects, namely magnitude, strength, and generality. The method used was survey method. The samples of this research were 160 students of class X of academic year 2017/2018 taken from Public High School (SMAN) 1, Public High School (SMAN) 2, Public High School (SMAN) 4, Public High School (SMAN) 5 and Public High School (SMAN) 6. The results of the study showed that the average self-efficacy of students are 58.60 on magnitude aspect with the medium category, 56.85 in strength aspect with the medium category, and 48.70 in generality aspect with the low category. Based on the results of this study, it is necessary to improve the learning process especially by using models of learning that can improve students' self-efficacy in Biology Lessons.

Creative thinking is used to solve problems that cannot be solved using conventional methods. Creative thinking refers to the ability to produce new and different concepts, solutions, or ideas (Sternberg, 2003). The thought process underlying creative answers is based on the person's skills, knowledge, understanding, motivation and emotions (Ferrari et al., 2009). In psychological research, creative thinking is usually defined as a process that leads to new, original, useful, and effective products. A creative mind is characterized by its flexibility that encourages someone to imagine innovative answers to a question (Runco & Jaeger, 2012).

Salah satu upaya yang dapat dilakukan masyarakat dalam menghadapi kondisi pandemi Covid-19 yaitu hendaknya lebih terampil dalam memanfaatkan sumber daya yang ada. Adapun tujuan dilakukan pengabdian kepada masyarakat yaitu untuk memberikan pelatihan Budikdamber sebagai ketahanan pangan keluarga masyarakat di Kota Bengkulu. Kegiatan dilakukan di Perumahan Puri Mas dengan kondisi pekarangan yang sangat terbatas, sehingga menjadikan kegiatan pelatihan ini tepat sasaran. Meskipun dengan lahan pekarangan yang terbatas dan sempit, namun dengan adanya hasil dari Budikdamber dapat membantu masyarakat dalam memenuhi kebutuhan pangan sehari-hari, bahkan jika dimaksimalkan dapat dipasarkan. Adapun metode yang digunakan dalam kegiatan pengabdian ini yaitu sosialisasi atau penyuluhan yang diawali dengan analisis situasi, pelatihan dan praktik, dan evaluasi dengan didampingi oleh tim dosen. Selanjutnya kegiatan dilanjutkan dengan memantau hasil uji coba. Adapun hasil kegiatan menunjukkan bahwa kegiatan Budikdamber memberi pengetahuan dan keterampilan baru bagi masyarakat yang dapat diaplikasikan langsung secara mandiri dan biaya murah.

Salah satu cara yang dapat dilakukan oleh masyarakat dalam menghadapi dampak penurunan ekonomi dan adanya kebijakan yang mengharuskan merumahkan sebagian besar pekerja selama masa pandemi yaitu membuat usaha sampingan sebagai solusi yang dapat dilakukan untuk menopang perekonomian. Hal ini juga dirasakan oleh masyarakat Kota Bengkulu, yang mana untuk memulai usaha tersebut diperlukan suatu keterampilan, kreatifitas dan inovasi dalam membuat produk yang bernilai jual tinggi, bermanfaat dan dapat memenuhi kebutuhan pangan masyarakat selama masa pandemi, misalnya dalam pembuatan Nata de Coco. Namun, fakta menunjukkan bahwa pengetahuan dan keterampilan yang dimiliki masyarat kota Bengkulu dalam membuat Nata de Coco masih sangat kurang. Oleh sebab itu, tujuan dilaksanakan pengabdian masyarakat ini yaitu untuk memberikan pengetahuan dan meningkatkan keterampilan masyarakat dalam membuat produk Nata de Coco. Adapun kegiatan ini dilakukan melalui metode ceramah (penyuluhan), pelatihan (praktik) dan diskusi tanya jawab. Sebagai hasil pengabdian dan masyarakat ini, meningkatnya pengetahuan dan keterampilan masyarakat kota Bengkulu terkait bahan yang diperlukan, prosedur pembuatan dan hal-hal yang perlu menjadi perhatian dalam membuat Nata de Coco. Selain itu masyarakat menjadi lebih kreatif dalam mengemas produk yang akan siap dipasarkan.
