AbstractThe aims of this study is describe developed worksheet to practice science process skills oriented greenchemistry on acid base material. This worksheet was arranged based on the components of scienceprocess skills, mainly; doing observation, making hypotheses, planning research, classifying data, andmaking conclutions. The principles of green chemistry in this study were limited to 3 principles such asnumber 1 about waste prevention, number 7 about using of renewable feedstocks, and number 12 aboutconditioning for accident prevention. The design of this study is used a 4-D (define, design, develop anddesseminate), however, this study is only limited to develop and conduct a limited test of 12 students ofclass XI IPA SMA 14 Surabaya. The feasibility of worksheet discussed includes: 1) validity in terms ofcontent validity and construct validity, 2) practicality in terms of student activities and studentquestionnaire responses, and 3) effectivity in terms of science process skills tests (pretest and posttest).The results showed that the feasibility of worksheet in terms of content validity was said to be valid with apercentage of 80.36% and construct validity was said to be very valid with an overall average percentageof 83.89%. Practicality in terms of student activities and student responses obtained very practical resultswith a percentage of 90.28% and 95.49%. The effectiveness in terms of the results of the science processskills test got n-gain score ranging from 0.66-0.88 on the medium-high category so that the developmentof worksheet is feasible use in learning.Key words: Student Worksheet, Science Process Skills, Green Chemistry

Penelitian ini bertujuan untuk mendeskripsikan kelayakan LKPD berorientasi inkuiri terbimbing untuk meningkatkan kemampuan literasi sains pada materi faktor-faktor yang mempengaruhi laju reaksi. Metode penelitian pengembangan menggunakan model pengembangan perangkat yang disarankan oleh Thiagarajan yaitu model 4-D yang dibatasi hanya sampai tahap develop. Ukuran kelayakan ditinjau berdasarkan 3 aspek, yaitu: validitas, kepraktisan, dan keefektifan. Validitas ditinjau berdasarkan kriteria isi, penyajian, kebahasaan, dan kegrafikan. Kepraktisan diperoleh melalui respon dan aktivitas peserta didik selama pembelajaran menggunakan LKPD yang dikembangkan. Sedangkan keefektifan ditinjau melalui tes kemampuan literasi sains yang diujikan secara terbatas kepada peserta didik SMAN 1 Kebomas Gresik sebanyak 12 orang dengan pembelajaran menggunakan model inkuiri terbimbing. Analisis data menggunakan metode deskriptif kuantitatif. Hasil menunjukkan persentase validitas LKPD masing-masing kriteria mendapat skor diantara 80%-89,63% dan dinyatakan valid. LKPD yang dikembangkan mendapatkan respon yang positif dengan persentase sebesar 97,5% dan dinyatakan sangat praktis serta didukung aktivitas peserta didik yang sangat baik dengan persentase sebesar 98,62%. Hasil peningkatan kemampuan literasi sains tergambar dalam skor N-Gain yang diperoleh pada rentang 0,45– 1,00 dengan kategori sedang-tinggi, untuk N-Gain 3 domain yang terikat satu sama lain (konteks, pengetahuan, dan kompetensi) mendapat skor 0,77 dengan kategori tinggi, sedangkan domain sikap mendapat skor N-Gain sebesar 0,33 dengan kategori sedang, didukung dengan ketuntasan klasikal pada tes akhir memperoleh persentase sebesar 100%, sehingga LKPD dinyatakan efekif.

Abstract This study intends to describe the feasibility of student worksheet with guided inquiry-oriented to improve the ability of scientific literacy on factors that influence the reaction rate matter. The development research method uses the device development model suggested by Thiagarajan which is a 4- D model that is limited to the develop stage. Feasibility measure were reviewed based on 3 aspect, namely: validity, praticality, and effectiveness. Validity is reviewed based on content, presentation, linguistic, and graphic criteria. Praticallity is obtained trough the respones and activitiesof student during learning using the developed student worksheet. While effectiveness is reviewed trough test of scientific literacy skills that were tetsted limited to 12 students of Senior High School 1 Kebomas Gresik by using the guided inquiry model. Analysis of the data uses quantitative descriptive methods. The results show the percentage of student worksheet validity of each criterion scores between 80% -89.63% and declared valid. The developed student worksheet received a positive response with a percentage of 97.5% and was declared very practical and supported by very good student activity with a percentage of 98.62%. The results of increasing scientific literacy ability are illustrated in the N-Gain score obtained in the range of 0.45–1.00 in the medium-high category, for N-gain 3 domains that are bound to each other (context, knowledge, and competence) get a score of .,77 with a high category, while the attitude domain received an N-gain score of 0.33 in the medium category, supported by classical completeness in the final test, getting a percentage of 100%, so that the student worksheet was declared effective.

Telah dilakukan penelitian pengembangan bahan ajar mata kuliah Kimia Dasar dengan wawasan green chemistry. Kimia sebagai ilmu yang berdasarkan eksperimen, tidak lepas dari aktivitas laboratorium yang membutuhkan bahan kimia, yang biasanya didapatkan dari industri bahan kimia.  Sebenarnya kimia sangat dekat dengan kehidupan keseharian siswa. Oleh karena itu pembelajaran kimia dirancang dengan memanfaatkan produk alami disekitar siswa. Salah satunya dengan memanfaatkan beberapa jenis tanaman atau bunga berwarna yang ada disekitar kehidupan siswa sebagai indikator asam dan basa alami. Metode penelitian menggunakan rancangan penelitian pengembangan (R&D). Hasil penelitian menunjukkan bahwa pemanfaatan produk alami terbarukan  sebagai pendukung pembelajaran dapat memenuhi salah satu prinsip green chemistry yaitu "penggunaan bahan baku terbarukan". Dalam penelitian ini beberapa bunga berwarna diidentifikasi dan berpotensi dimanfaatkan sebagai indikator asam basa alami dalam pembelajaran kimia antara lain bunga pacar air dan Ruellia.  Dengan menggunakan bahan alami dapat menjaga keberlanjutan proses pembelajaran kimia tanpa tergantung bahan kimia buatan industri.Kata Kunci : green chemistry, pembelajaran kimia, indikator alami.

Recently the trend of words in the world is related to sustainable development such as "green" has become a new trend in everyday human life.  This study aimed to analyze and map the chemistry learning with green chemistry insight for undergraduate students of chemistry education program as an effort to conserve the environment as one of the Sustainable Development Goals (SDGs). The urgency of this study is to support the achievement of SDGs through education, especially the target number 12, responsible consumption and production and/or number 13, climate action. Data collection was used in exploratory method by combining primary and secondary exploratory framework. The primary method was focused on the observation qualitative or quantitative and the secondary on the literature research.  Data analysis were used qualitative and quantitative descriptive.  It can be concluded that; the efforts to preserve the environment through education can be pursued with green chemistry insight learning. The principles of green chemistry that can be implemented in chemistry learning on suitable material represent in some action such as; waste prevention, use the safe solvent, energy efficiency, and creating safe and secure conditions for learning both in the classroom and laboratory. Chemistry learning have the role to support SDGs through education by using some learning model/methods, such as discussion, concept map, or practical methods as well as Project Based Learning. So, the results of this study can be referred as an alternative learning that have contribution in SDGs achievement through education.
