Abstract

Tujuan penelitian ini untuk menganalisis kesulitan mahasiswa dalam mengembangkan RPP dan menganalisis hubungan nilai RPP yang diperoleh mahasiswa dengan kesulitan mahasiswa dalam mengembangkan RPP. Jenis penelitian ini adalah penelitian deskriptif dengan menggunakan pendekatan kualitatif. Subjek penelitian sebanyak 50 mahasiswa. Teknik pengumpulan data dilakukan dengan menggunakan angket. Hasil penelitian menunjukkan bahwa persentase rata-rata kesulitan mahasiswa dalam mengembangkan RPP sebesar 76,48% dengan kategori sedang. Terdapat 8 komponen RPP yang memiliki tingkat kesulitan sedang, yaitu  Indikator Pencapaian Kompetensi, materi ajar, alokasi waktu pada langkah-langkah pembelajaran, kegiatan pendahuluan, kegiatan inti, teknik penilaian hasil belajar, instrumen penilaian pengetahuan (kognitif), dan instrumen penilaian keterampilan (psikomotorik). Adapun komponen RPP yang memiliki tingkat kesulitan tinggi yaitu komponen metode pembelajaran. Hasil uji statistik korelasi product moment diperoleh nilai r sebesar 0,89, sedangkannilai thitung 13,54 sedangkan nilai ttabel pada taraf signifikan 0,05 adalah 2,01, menunjukan bahwa thitung> ttabel maka Ha diterima dan Ho ditolak artinya terdapat hubungan yang signifikan antara kesulitan yang dialami mahasiswa dalam mengembangkan RPP dengan nilai RPP yang diperoleh.

Abstract

This research has isolated one type of halophilic bacterial strain from the salt pond of Kajhu Village with the code KJ-AB2. This bacterium grew optimally at 10% (w/v) NaCl so it was classified as moderate halophilic bacteria. Several types of halophilic bacteria are known to produce biosurfactants. Biosurfactants are surface active agents that are widely used in several pharmaceutical, food dan petroleum industries. The production of biosurfactants is strongly influenced by the type of carbon source used for bacterial growth. Olive oil, palm oil, sunflower oil, glucose dan glycerol are types of carbon sources used to see their effect in producing biosurfactants. This isolate growed well on the five carbon sources with an average OD600 2.001±0.293 at 72 hours of fermentation. Biosurfactant production was measured by oil spreading test (OST) every 24 hours until 120 hours of fermentation. The highest OST value was obtained when KJ-AB2 isolate was grown on biosurfactant production media using olive oil, sunflower oil dan palm oil with an average OST value of 5.6±0.6 cm, 4.7±0.6 cm, dan 4.6±0.7 cm, respectively.

Abstract

To further improve achievement of the given learning objectives, chemistry learning requires instructional materials that encourage active engagement of students. The goal of this research was to create student worksheets based on Peer Led Team Learning (PLTL) on colloid material, to establish the validity of student worksheets based on PLTL on colloid material, and assess teacher and student responses to worksheets. PLTL based students on colloid material that has been developed. This research approach is known as research and development (R&D), and it is carried out utilizing the 4D model (define, design, develop, and disseminate). Purposive sampling was used for the sample technique. The study was carried out at four schools: MAN 3, SMAN 5, SMAN 12, and SMAN 15 Adidarma Banda Aceh. Validating the practicality of student worksheets and questionnaire responses from teachers and students were used to obtain data. This study obtained the following results: (1) validation of the feasibility of student worksheets by expert validators of 92.3% and based on the chemistry teacher's assessment of 86.5% in the very good or valid category; (2) results of the teacher's responses to the students' worksheets obtained a percentage of 88.1% in the very good category; and (3) results of the students'responses to the students' worksheets obtained a percentage of 79.9% in the good category. Based on the findings, it is possible to infer that the student worksheet based on PLTL on colloid material is appropriate for use as teaching material on colloid material.
