Abstract

The use of natural extracts from plants mobilized onto solid media as acid-base and pH indicators is being attention of researchers. The mobilization of the ethanol extract of Syzigium oleana shoot leaves has been done and produces paper indicator that can be changed its colorin different pH. This study was designed to determine the effect of temperature on the adsorption of the ethanol extract of S. oleana shoot leavesonto filter paper. The ethanol extract of S. oleana shoot leaves was obtained by using maceration technique for 24 hours with material liquor ratio (MLR) of 1: 7. The adsorption ofethanol extract of S. oleana shoot leaves onto filter paper was carried out at different temperature, i.e. 27°C, 52°C and 81°C with MLR of 1: 100, filter paper weight of 0.2949 ± 0.0035 gram and solution volumeof 30 mL for 2 hours. The results showed that temperature effect on the adsorption of ethanol extract of S. oleana shoot leaves onto filter paper. The % adsorption of S. oleana shoot leaves onto filter paper increased with an increase in the temperature. Keywords : pucuk daun pucuk merah, Syzigium oleana, temperature, adsorption

Abstract

One effort that can be done to help teachers is to offer a variety of alternative learning as inspiration for teachers in teaching. As one of the learning theory, theory of Bruner could be one appropriate strategies used in improving student learning outcomes in learning the cone. To reveal the effectiveness of cone learning based on Bruner’s theory, this research uses a quantitative approach with this type of research is quasi experiment. The design of this research is the one-group pre-test-post-test design. The subject is a student of class IX Junior High School. Data collection is done with the test results of the study, observation and question form. The results showed that the activity of students to each category on each RPP is effective, the ability of teachers in managing cone learning based on Bruner’s theory is effective at RPP I achieved an average of 4.44 and on RPP II reaches an average of 4.50. Student response against cone learning based on Bruner’s theory is effective where > 80% of students gave a positive response. Student learning results indicates that 20 students (71.43%) completely studied, while the 8 students (28.57%) is not thoroughly studied. Thus it can be concluded that the mastery learning of classical learning was not met. Even so, there was a significant increase in the mastery learning in Bruner's theory with cone in classical i.e. amounting to 50%. For the students who hadn't learned i.e. 8 students (28.57%) will be given additional duties as well as remedial and homework to help students understand the material cone hadn't he learned.

Abstract

This paper aimed to reveal the readiness of Junior High Schools in Banda Aceh and Jombang to implement e-learning based on the teacher's perspective through six factors of e-learning readiness, including student readiness factors, teacher readiness, infrastructure readiness, school culture readiness, and face-to-face learning tendencies. Data was collected through an online questionnaire, involving 69 students from various junior high schools. The findings of this study showed that the readiness for implementing e-learning in Junior High Schools in Banda Aceh and Jombang was at a score of 3.5 and was in the ready category but still needed improvement. Six factors were the basis for determining the readiness to implement e-learning, four of which were in the ready category but required a slight improvement of student readiness factor, teacher readiness factor, school culture readiness, and management readiness. While, the other two factors were in the unready category including the infrastructure readiness factor and readiness for face-to-face learning tendencies. Keywords: e-learning, readiness, teachers’ perspective, junior high school

Abstract

Abstrak— Banda Aceh merupakan ibukota dari Provinsi Aceh yang memiliki sembilan kecamatan. Banda Aceh memiliki tingkat persebaran penduduk miskin yang tinggi di masing-masing kecamatannya. Jumlah penduduk miskin di Kota Banda Aceh mencapai 7,72% dari total penduduk 250.303 jiwa atau sekitar 19.300 jiwa. Jumlah penyebaran penduduk miskin disetiap kecamatan Kota Banda Aceh belum terpetakan dengan baik. Hal ini bisa menyulitkan pemerintah di dalam mengambil tindakan yang efektif di dalam mengurangi penyebaran penduduk miskin secara terfokus. Dibutuhkan sebuah sistem pemetaan berbasis sistem informasi geografis (SIG) untuk menggambarkan penyebaran penduduk miskin disetiap kecamatan Kota Banda Aceh. SIG ini dapat menggambarkan kecamatan yang memliliki tingkat penduduk miskin terendah sampai tertinggi menggunakan data dari Badan Pusat Statistik (BPS) Kota Banda Aceh. Perancangan SIG ini berjenis penelitian kualitatif menggunakan metode deskriptif. Aplikasi Quantum GIS digunakan sebagai pengolah dan pembuatan SIG pemetaan penyebaran penduduk miskin di Kota Banda Aceh. Hasil akhir perancangan SIG berbentuk webmap. Kata kunci: Penduduk Miskin, Webmap, Banda Aceh, Quantum GIS, Pemetaan
