Pandemi COVID-19 (Corona Virus Disease) telah memberikan dampak luas terhadap berbagai sektor kehidupan masyarakat, tidak terkecuali dalam sektor ekonomi. Salah satu pelaku ekonomi terdampak akibat adanya pandemi adalah Kelompok Petani Wanita Jahe (KPWJ) Kota Malang. Produk hilir yang dihasilkan KPJW adalah sirup rempah JaEnak yang memiliki nilai penjualan yang rendah, yakni kurang dari 100 pak/bulan, padahal Sirup JaeNak berpotensi meningkatkan imunitas tubuh di masa pandemik. Telah dilaksanakan upaya peningkatan pemasaran dengan memberikan pelatihan Branding Awarness dengan sumber dana PKM Universitas Negeri Malang. Metode peningkatan pemasaran dilaksakan dengan memberikan pelatihan digital marketing sebagai bagian dari Branding Awarness untuk memperbaiki pola pemasaran tradisional. Peserta pelatihan adalah anggota PKJW dan pertisipan PKJW. Metode evaluasi hasil pelatihan dilaksanakan dengan analisis deskriptif atas hasil kuisioner kepada peserta pelatihan. Hasil kusisioner menunjukkan bahwa peserta siap menerapkan hasil pelatihan. Pelatihan digital marketing ini menghasilkan media sosial pemasaran bagi PKJW yakni IG https://instagram.com/kampungbejo_malang?igshid=YmMyMTA2M2Y=. Telah dihasilkan kesadaran legalitas produk dalam bentuk terbitnya PIRT dan evolusi nama produk sirup menjadi wejangan sebagai bentuk branding developing. The COVID-19 (Corona Virus Disease) pandemic has broadly impacted various sectors of people's lives, including the economic sector. One of the economic actors affected is the Women Ginger Farmer Group (KPWJ) in Malang City. KPJW produced JaEnak spice syrup with a low sales value of fewer than 100 packs/month, even though JaeNak syrup can potentially increase body immunity during a pandemic. The efforts to improve marketing could be by providing Branding Awareness training with funds from the State University of Malang (UM) Community Service. The marketing improvement method is carried out by providing digital marketing training as a part of Branding Awareness to improve traditional marketing patterns. The training participants were PKJW members and others. We evaluated the training results by using descriptive analysis of some questionnaires. As a result, the participants were ready to apply for this Digital Marketing training. This training has some outcomes: social media marketing for PKJW, namely IG https://instagram.com/kampungbejo_malang?igshid=YmMyMTA2M2Y=. As the representation of awareness of branding, we also achieved the legality of the product in the form of the publication of PIRT and the evolution of the name of the syrup product.

Correlational reasoning is a crucial skill for students in their daily lives. Correlational reasoning, therefore, should be taught in formal schools. However, a study about the improvement of correlational reasoning in instruction is still rarely disclosed. This study aims to explore the change in students' correlational reasoning through STEM-based phenomenon learning. This study used a mixed-method approach involving 25 high school students in Malang, Indonesia. The result of this study showed that correlational reasoning could be taught in a classroom setting. Students' correlational reasoning was improved after experiencing STEM-based phenomenon learning. The dominance is that students are still at level 2 - students show answers but are not related to each other, and level 3 - student explanations are only appropriate for one relationship. The study also showed that the most significant obstacles of students when they applied correlational reasoning was the failure to involve the whole variables related to a phenomenon. For further research, it is recommended to implement STEM-based phenomenon learning for longer durations.

In this paper, we report the utilization of Morus alba L. leaves extraction in the preparation of SiO2/ZnFe2O4 nanocomposites. Preparation of the extinction SiO2/ZnFe2O4 nanocomposites based on Morus alba L. leaves was successfully carried out using coprecipitation and sol-gel methods. The SiO2/ZnFe2O4 nanocomposites were characterized using XRD, FTIR, and SEM-EDX. Based on the characterization carried out, structurally, the sample had two phases under its precursor, namely the crystalline phase for ZnFe2O4 and the amorphous phase for SiO2. The SiO2/ZnFe2O4 nanocomposites had a particle size of approximately 6.4 nm. Referring to FTIR spectra analysis, the precursors of nanocomposite constituents were detected based on their characteristic stretching band. The M-O stretching band representing the bond between Zn-O and Fe-O was discovered in the 471 cm−1 regions. Furthermore, stretching bands that represent the presence of SiO2 were in the area of 801 and 1083 cm-1, which represent Si-O-Si bonds, and in the region of 954 cm−1, which was a Si-OH stretching band. Finally, there were two characteristic stretching bands possessed by Morus alba L. namely, terpenoids (= N-H) and alkaloids (-N-H) in the areas of 1635 and 1396 cm−1, respectively. Based on a morphological characterization review, information was obtained that formed a particle cluster, which is a combination of primary and secondary particles with an average particle size of 38.1 nm. The elemental content characterization via EDX confirmed that all precursor elements were detected originating from matrix and filler.
