Abstract

STEM (Science, Technology, Education, and Mathematics) adalah salah satu pendekatan pembelajaran sains terintegrasi yang bermanfaat untuk melatihkan problem solving skills dan keterampilan abad 21, serta menjadi salah satu model pembelajaran inovatif yang disarankan untuk diterapkan di kelas sains. Permasalahannya adalah kurangnya pengetahuan dan keterampilan guru tentang STEM, sehingga hampir tidak ada yang menerapkannya. Oleh karena itu tujuan dari kegiatan pengabdian ini adalah memberikan wawasan pengetahuan dan keterampilan kepada guru bagaimana mendesain dan menerapkan STEM, terutama pada masa pandemi. Mitra pada kegiatan pengabdian ini adalah guru-guru Biologi yang tergabung dalam Musyawarah Guru Mata Pelajaran Biologi Karanganyar, Jawa Tengah dan guru-guru Biologi anggota Persatuan Pendidik Biologi Indonesia Folia (PPBIF) cabang Jawa Tengah (N=53). Kegiatan ini berupa workshop yang dilaksanakan sebanyak 5 pertemuan secara online dengan tema: Pengantar STEM, Problem-based Learning dan Project-based Learning, STEM@Home, Desain STEM, dan Evaluasi STEM. Hasil pendampingan menunjukkan adanya peningkatan pengetahuan dan keterampilan guru dalam menyusun Desain STEM dan rencana pembelajarannya. Persepsi guru tentang STEM juga meningkat terkait dengan aspek-aspek yang perlu diperhatikan dalam penerapan STEM@Home pada masa pandemi. Diperlukan implementasi STEM lebih lanjut di kelas pembelajaran jarak jauh untuk melihat keefektifan pendampingan

Abstract

Four endophytic bacteria have been isolated from banana kluthuk plants and banana ambon. Previous study showed that they produce Indole Acetic Acid (IAA). This study aimed to analyze the effect of endophytic bacterial inoculation on plant height and the number of rice root. For this reason, two endophytic bacteria of each klutuk banana and ambon banana plants were cultured and examined for growth rate using a 600 nm spectrophotometer. Isolate growth was calculated every two hours for 16 hours of bacterial growth in NB media. Bacterial inoculation experiments on rice plants were carried out with five replications. This inoculation begun with germination of rice seeds until the radicle was observed. Then germinated rice seedlings were soaked in a bacterial suspension for 1 hour at room temperature. The results showed the exponential phase of all isolates was observed at 6 hours with shaking. Inoculation using A22 and A51 isolates significantly increases plant height, number of leaves. While, A22 isolate significantly increased the number of roots compared to the uninoculated plants (control). It supports the potential of endophytic bacteria from banana kluthuk and ambon plants.

Abstract

Questionnaires are commonly utilized on educational research. However, studies on Differential Item Functioning (DIF) and calibration using Rasch Models are still limited. Therefore, a Self-regulated Learning questionnaire was developed which aims to determine the ability of students to regulate themselves to achieve learning goals. The instrument consists of twelve items. The involved participants were 300 students who enrolled in first-year to fourth-year. Data were analyzed using Racsh Model Analysis with Winsteps 4.5.2 software. As a result, there are four items that were not fit, so that, therefore should be eliminated or revised. The DIF analysis found that gender bias was unidentified, but long-study bias was detected for items number one and six. The reliability value of the item is categorized as very good (0.99), which indicates that the instrument has sufficient consistency/reliability. While, the function curve showed that the items on the self-regulated learning questionnaire produce optimal information in individuals with moderate (θ) ability. Overall, self-regulated learning questionnaires have to be revised then tested on different sample groups. In addition, longitudinal and cross-sectional research is necessary to determine the level of self-regulated learning of students more comprehensively.

Abstract

The bacteria found in the rhizosphere are called plant growth promoting rhizobacteria (PGPR), namely bacteria that can stimulate plant growth by producing growth hormones, one of which is the hormone indole acetic acid (IAA) which plays a role in regulating plant growth and development. Five isolates of rhizosphere bacteria were isolated on frangipani roots (P26, P31, P36, P37 and P38). Previous research showed that five bacterial isolates were capable of producing the hormone IAA. However, evidence of its potential as a PGPR has not been obtained. Therefore, the aim of this study was to test the effect of inoculation of rhizosphere bacteria on maize plants. The research method uses a quantitative experimental method, namely 15 repetitions for each treatment. Data collection was carried out 1 day after planting (HTS) until the 14th day. Data were analyzed using a 95% confidence student t-test or with a significance level of 5% (a=0.05). This inoculation begins with germinating maize seeds and observing the roots. The germinated maize seeds are then soaked in the bacterial suspension for one hour at room temperature. The results showed that inoculation with isolates P36, P37 and P38 significantly increased the height of maize plants, while isolate P37 significantly increased the number of leaves and root length of corn plants, isolate P38 could significantly increase the number of roots of corn plants.Thus, these results support the evidence that rhizosphere bacteria from frangipani have an effect on increasing the growth of maize plants

Abstract

Trend of Learning of XXI century  is full of skills, one of skills is social skill. In fact, learning by rote is the most applicated in junior high school in Indonesia. One example of junior high school happened in VIIIB class of UM laboratory  school. Module system has been applying there. It causes individual learning so that reduces the social interaction and social skill. One of the solutions for this problem is TGT-GI strategy, it is included to cooperation model of learning.  This research is conducted based on lesson study class action. Aim of the research is to improve student’s social skill by application of TGT-GI strategy in VIIIB Class of UM Laboratory Junior High School. The results of this research shows the average of student’s social skills was 19,34 % increased. In wich 32,44 in the I cycle and 38,71 in the II cycle. Based on this result, it was clocluded that TGT-GI strategy able to improve student’s social skills in VIIIB Class of UM Laboratory Junior High School.
