Abstract

Karakter kolaborasi dan kreatif dapat membantu siswa menjadi individu yang lebih baik. Terhambatnya kolaborasi siswa akan berdampak pada kreativitasnya, sehingga guru perlu mendorong dan memfasilitasi siswa untuk berkolaborasi, misalnya melalui pembelajaran berbasis proyek. Penelitian ini bertujuan untuk mendeskripsikan karakter kolaborasi dan kreatif yang dibentuk melalui pembelajaran berbasis proyek pada materi sistem koloid. Jenis penelitian ini adalah deskriptif kuantitatif dengan partisipan 162 siswa kelas X SMA Mujahidin Pontianak yang dipilih menggunakan teknik sampling jenuh. Pengumpulan data dilakukan melalui observasi dengan menggunakan instrumen lembar pengamatan karakter kolaborasi dan kreatif yang telah divalidasi oleh dua orang ahli di bidang pengembangan karakter. Hasil penelitian menunjukkan bahwa karakter kolaborasi siswa berada dalam kriteria sangat berkembang, sedangkan karakter kreatif berada dalam kriteria berkembang sesuai harapan. Nilai rata-rata persentase karakter kolaborasi seperti: berkontribusi pada diskusi kelompok (88,43%), bekerja secara efektif dalam kelompok (94,52%), dan berkomunikasi dalam kegiatan kelompok (83,13%) berada dalam kriteria sangat berkembang, sedangkan memiliki tanggung jawab untuk menyelesaikan tugas kelompok (78,24%) berada dalam kriteria berkembang sesuai harapan. Sementara nilai rata-rata persentase karakter kreatif seperti menghasilkan gagasan yang orisinal (74,13%) dan menghasilkan karya dan tindakan yang orisinal (74,79%) berada dalam kriteria berkembang sesuai harapan, sedangkan memiliki keluwesan berpikir dalam mencari alternatif solusi (55,02%) berada dalam kriteria mulai berkembang. Oleh karena itu, karakter kolaborasi dan kreatif dapat dibentuk melalui pembelajaran berbasis proyek pada materi sistem koloid. Perlu adanya penelitian lanjutan untuk menganalisis kendala yang dihadapi siswa dalam berkreativitas, meskipun telah menunjukkan kolaborasi yang sangat baik dalam kelompok.

Abstract

Rimpang jahe merah digunakan sebagai tumbuhan obat tradisional dan diketahui mengandung senyawa-senyawa berkhasiat. Dekade ini eksplorasi mikroorganisme yang bersimbiosis dengan tumbuhan obat mendapat perhatian besar guna mencari alternatif sumber senyawa berkhasiat obat. Penelitian ini bertujuan memperoleh informasi profil kimia ekstrak Penicillium simplicissimum, jamur endofit yang diisolasi dari rhizoma jahe merah, menentukan daya hambatnya terhadap bakteri Staphyloccocus aureus dan Escherichia coli, dan mengevaluasi aktivitas sitotoksiknya terhadap sel limfoma tikus L-5178Y, sel kanker payudara (T47D dan 4T1) dan sel kanker usus (WiDr). Skrining fitokimia melalui teknik KLT dan pereaksi spesifik memperlihatkan adanya golongan senyawa alkaloid, triterpenoid, dan sterol pada ekstrak. Analisa data high-performance liquid chromatography dengan detektor photodiode array (HPLC-PDA) yang dikombinasikan dengan data LC-ESI-MS serta perbandingan data literatur memberikan dugaan bahwa salah satu komponen senyawa utama adalah citreonigrin F, yang diisolasi sebelumnya dari P. citreonigrin. Evaluasi aktivitas antibakteri menunjukkan bahwa ekstrak P. simplicissimum tidak memiliki daya hambat terhadap pertumbuhan kedua bakteri uji. Akan tetapi, ekstrak P. simplicissimum memberikan penghambatan yang lemah terhadap sel limfoma tikus L-5178Y pada konsentrasi 10 μg/mL dan aktivitas sitotoksik yang moderat terhadap sel kanker payudara dan sel kanker usus dengan IC50 >100 μg/mL. Temuan ini menunjukkan bahwa jamur endofit P. simplicissimum yang diisolasi dari jahe merah ini memiliki potensi untuk dieksplorasi lebih lanjut guna memperoleh senyawa berkhasiat obat.  Profiling Analysis of HPLC-PDA Combined with LC-ESI-MS and Biological Activity of an Endophytic Fungi P. Simplicissimum Extract Isolated from Red Ginger Rhizome. Red ginger rhizome has been used traditionally as a medicinal plant, and its active principal constituents have been known. In the recent decade, the exploration of endophytes in medicinal plants received huge interest in finding new bioactive compound sources. This research aims to obtain the chemical profile of an endophytic fungi P. simplicissimum extract isolated from Red ginger rhizome. This study also further evaluates its antibacterial activity against Staphyloccocus aureus and Escherichia coli and its cytotoxicity against L-5178, 4T1, T47D, and WiDr cell lines. The phytochemical screening of the extract using the TLC technique and specific reagents shows the existence of alkaloids, triterpenoids, and sterol. The further analysis using high-performance liquid chromatography with photodiode array detector (HPLC-PDA) and LC-MS/MS data, as well as literature comparison, indicated that one of the major compounds was citreonigrin F, which isolated previously from P. citreonigrin. The evaluation of antibacterial activity showed that P. simplicissimum extract did not inhibit the growth of both bacteria tested. However, P. simplicissimum extract showed a weak inhibition against L-5178Y rat lymphoma cells at a concentration of 10 μg/mL and a moderate cytotoxic activity against breast cancer cells and colon cancer cells with IC50 >100 μg/mL. Nevertheless, this study showed that P. simplicissimum isolated from red ginger could be further explored for its bioactive compounds.

Abstract

Deep Learning is an educational approach that focuses on improving the quality of learning and students’ learning experiences. One of the learning strategies that integrates the Deep Learning approach is the use of technology, such as transforming printed student worksheets (LKPD) into electronic worksheets (E-LKPD). E-LKPDs not only contain direct-question tasks but can also be modified through gamification, which represents an integration of the Deep Learning approach. This study aimed to develop a feasible and effective Deep Learning-based E-LKPD to improve students’ learning outcomes in Science and Social Studies (IPAS). The research employed the ADDIE development model consisting of Analysis, Design, Development, Implementation, and Evaluation stages. The results indicated that all three E-LKPDs were highly feasible. E-LKPD 1 achieved feasibility scores of 92.9% (didactic aspect), 85% (construction aspect), and 80% (technical aspect). E-LKPD 2 obtained 91.4%, 85%, and 80%, respectively, while E-LKPD 3 achieved 90%, 84%, and 81.25%, respectively. The N-Gain test showed that all three E-LKPDs were moderately effective in improving students’ IPAS learning outcomes on the topic My Region, My Pride in Grade V of SDN 36 South Pontianak, with N-Gain scores of 62.8%, 62.3%, and 62.1%, respectively. Student responses were highly positive overall. The three E-LKPDs received very positive ratings in terms of appearance (84.5%–85.3%) and usefulness (85.8%–86.4%), while presentation aspects were rated positively (82.6%–83.8%). These findings suggest that Deep Learning-based E-LKPDs are feasible, effective, and well-received as learning media.

Abstract

Chemistry learning in secondary schools is still predominantly theoretical, limiting students' opportunities to connect scientific concepts with contextual and environment-based learning experiences. As a result, the use of the surrounding environment as a learning resource, as well as the development of creativity, environmental awareness, and twenty-first-century skills, has not been fully optimized. This community service program aimed to implement ecoprint training as an innovative approach to environment-based chemistry learning and to evaluate its impact on students' knowledge and skills, environmental awareness, creativity and critical thinking, green entrepreneurship, and collaborative learning. The program involved 171 tenth-grade students of SMAN 13 Pontianak and employed a hands-on training approach consisting of instructional sessions, ecoprint practice using locally available natural materials, reflective discussions, and post-activity evaluation using a five-point Likert-scale questionnaire. Data were analyzed using descriptive quantitative methods based on the mean scores of each evaluation aspect. The results indicated that all assessed aspects achieved good to very good categories, including knowledge and skills (3.75), environmental awareness (4.14), creativity and critical thinking (3.96), green entrepreneurship (3.91), and collaborative learning and partnership (4.04). In addition, the program produced dozens of naturally dyed ecoprint works collaboratively created by the participants as tangible outcomes of practice-based learning. These findings demonstrate that ecoprint training not only enhances students' understanding of chemistry concepts through experiential learning but also strengthens environmental literacy, creativity, collaboration, and awareness of sustainable entrepreneurship. This program offers an innovative environment-based chemistry learning approach that integrates scientific concepts, local natural resources, and sustainability values, providing a replicable model to support the implementation of Education for Sustainable Development (ESD) in schools.Pelatihan Ecoprint sebagai Inovasi Pembelajaran Kimia Berbasis Lingkungan bagi Siswa SMAN 13 PontianakABSTRAKPembelajaran kimia di sekolah menengah masih didominasi oleh pendekatan teoretis sehingga belum sepenuhnya menghubungkan konsep sains dengan pengalaman belajar yang kontekstual dan berbasis lingkungan. Kondisi ini menyebabkan pemanfaatan lingkungan sebagai sumber belajar serta pengembangan kreativitas, kepedulian lingkungan, dan keterampilan abad ke-21 belum optimal. Kegiatan Pengabdian kepada Masyarakat ini bertujuan mengimplementasikan pelatihan ecoprint sebagai pendekatan inovatif dalam pembelajaran kimia berbasis lingkungan serta mengevaluasi dampaknya terhadap pengetahuan dan keterampilan, kesadaran lingkungan, kreativitas dan berpikir kritis, green entrepreneurship, serta pembelajaran kolaboratif siswa. Kegiatan melibatkan 171 siswa kelas X SMAN 13 Pontianak melalui pendekatan hands-on training yang dipadukan dengan penyampaian materi, praktik pembuatan ecoprint menggunakan bahan alami lokal, diskusi reflektif, dan evaluasi menggunakan angket skala Likert lima tingkat. Data dianalisis secara deskriptif kuantitatif berdasarkan nilai rata-rata setiap aspek penilaian. Hasil menunjukkan bahwa seluruh aspek berada pada kategori baik hingga sangat baik, yaitu pengetahuan dan keterampilan (3,75), kesadaran lingkungan (4,14), kreativitas dan berpikir kritis (3,96), green entrepreneurship (3,91), serta kemitraan dan pembelajaran kolaboratif (4,04). Kegiatan juga menghasilkan puluhan karya ecoprint berbahan alami sebagai luaran pembelajaran berbasis praktik. Temuan ini menunjukkan bahwa ecoprint efektif sebagai pendekatan pembelajaran kimia berbasis lingkungan yang mengintegrasikan konsep sains, pemanfaatan sumber daya lokal, dan nilai keberlanjutan, serta berpotensi direplikasi untuk mendukung implementasi Education for Sustainable Development (ESD).Kata Kunci :Ecoprint; Pembelajaran Berbasis Lingkungan; Pendidikan Kimia; Pengabdian Masyarakat
