ANALISIS KETERAMPILAN PROSES SAINS MATERI KIMIA HIJAU MELALUI PROYEK BRIKET DAUN KARET

Abstract

Chemistry learning at the high school level is frequently dominated by the memorization of concepts and formulas, preventing students' Science Process Skills (SPS) from developing optimally. This study aims to analyze the SPS profile of 10th-grade students at SMA Negeri 3 Dusun Utara in Green Chemistry materials through a Deep Learning framework with a Project-Based Learning (PjBL) model involving a dry rubber leaf waste briquette project. The research method used is a qualitative descriptive method. The research subjects involved 12 tenth-grade students. Project activities were integrated through six PjBL syntaxes, aligned with five target SPS indicators from the national curriculum, and facilitated through structured worksheets on the Huma Betang Digital Class. Data were collected via SPS observation sheets, waste utilization questionnaires, interview guidelines for local planters, student response questionnaires, and documentation. The results revealed that the students' overall average SPS score reached 58.00% (Moderate category). In detail, the indicators for observing (score 3.50) and questioning/predicting (70.00%) achieved the High category. Conversely, competency declined in processing/analyzing data (50.00%; Moderate category) and reached its lowest point in evaluating/reflecting (40.00%; Low category) because formula memorization habits left students untrained in metacognitive thinking when encountering cracked or fragile briquette products. Meanwhile, the student response questionnaire demonstrated highly positive acceptance, yielding an overall average of 78.11% (Good criterion), with digital worksheet utilization achieving the highest score of 80.21%. This study concludes that the integration of PjBL and Deep Learning successfully transforms chemistry learning from mere theoretical transfer into a platform for contextual and meaningful science exploration. Future recommendations are directed toward enhancing problema solving based scaffolding interventions and downstreaming briquette technology with local planter communities to realize Green Chemistry principles sustainably.

ABSTRAK

Pembelajaran kimia di tingkat SMA sering kali didominasi oleh hafalan konsep dan rumus, sehingga mengakibatkan Keterampilan Proses Sains (KPS) siswa kurang berkembang secara optimal. Penelitian ini bertujuan untuk menganalisis profil KPS siswa kelas X SMA Negeri 3 Dusun Utara pada materi Kimia Hijau melalui kerangka Pembelajaran Mendalam (Deep Learning) dengan model Pembelajaran Berbasis Proyek (PjBL) berupa pembuatan briket dari limbah daun karet kering. Metode penelitian yang digunakan adalah metode deskriptif kualitatif. Subjek penelitian melibatkan 12 siswa kelas X. Aktivitas proyek diintegrasikan melalui enam sintaks PjBL, diselaraskan dengan lima indikator KPS target kurikulum nasional, dan difasilitasi melalui LKPD terstruktur pada Kelas Digital Huma Betang. Pengumpulan data dilakukan menggunakan lembar observasi KPS, angket pemanfaatan limbah, pedoman wawancara pekebun lokal, angket respons siswa, dan dokumentasi. Hasil penelitian menunjukkan rata-rata nilai KPS keseluruhan siswa sebesar 58,00% (kategori Sedang). Secara rinci, indikator mengamati (skor 3,50) serta mempertanyakan dan memprediksi (70,00%) berada pada kategori Tinggi. Namun, penurunan kompetensi terjadi pada indikator memproses/menganalisis data (50,00%; kategori Sedang) dan mengevaluasi/refleksi (40,00%; kategori Rendah) karena kebiasaan menghafal membuat siswa belum terbiasa berpikir metakognitif saat menghadapi kegagalan produk briket yang retak atau rapuh. Sementara itu, angket respons siswa menghasilkan rata-rata keseluruhan 78,11% (kriteria Baik), dengan pemanfaatan LKPD Digital menempati capaian tertinggi sebesar 80,21%. Penelitian ini menyimpulkan bahwa integrasi PjBL dan Deep Learning mampu mentransformasi pembelajaran kimia dari sekadar transfer teori menjadi wahana eksplorasi sains yang kontekstual dan bermakna. Rencana tindak lanjut diarahkan pada penguatan intervensi scaffolding berbasis problem solving serta perluasan hilirisasi teknologi briket bersama komunitas pekebun lokal guna mewujudkan prinsip Kimia Hijau secara berkelanjutan.
