Ekstraksi dilakukan dengan cara maserasi menggunakan pelarut etanol, dilanjutkan dengan penambahan etanol 70% dan penambahan petroleum eter karena alkaloid tidak larut dalam petroleum eter dan dilanjutkan dengan ekstraksi cair-cair menggunakan kloroform. Setiap fraksi dilakukan pemantauan menggunakan kromatografi lapis tipis dengan fase diam silika gel GF254 dan fase gerak n-heksana - etil asetat (7 : 3). Fraksi kloroform dikromatografi kolom menggunakan fase diam silika gel 60 G dan fase gerak n-heksana - etil asetat (20 : 1), isolasi dilakukan dengan kromatografi lapis tipis preparatif, diperoleh empat isolat kemudian dilakukan uji kemurnian dengan KLT 2 dimensi dan 3 fase gerak yang berbeda. Identifikasi spektrofotometri ultraviolet isolat menunjukkan adanya puncak serapan pada panjang gelombang 265 nm dan 268 nm. Identifikasi spektrofotometri inframerah isolat menunjukkan adanya serapan pada bilangan gelombang (cm-1) 3434,01 (gugus O-H dan N-H), 2922,98 dan 2852,87(gugus C-H), 1110,02 (gugus C-O) dan 1741,78, 1701,91 dan 1459,18 (gugus C=C aromatik). Isolat kemudian diidentifikasi dengan menggunakan pereaksi Dragendorff menunjukkan warna jingga sehingga isolat diduga mengandung alkaloid. Alkaloid tersebut diasumsikan berupa alkaloid yang memiliki ikatan rangkap terkonjugasi dan atau senyawa aromatis. Kata Kunci: isolasi, identifikasi, Brucea javanica Merrill, alkaloid, chlorofor
Volunteer Problems in Guiding Special Needs Students in Following Lectures
No full textVoluntary presence is an effort to help students
with special needs in learning. In addition, mentoring activities
carried out by volunteers are certainly not an easy task.
Therefore, this study aims to examine various problems faced by
volunteers in terms of cooperation with lecturers, attitudes of
students with special needs, and voluntary readiness. This
research was conducted using a qualitative approach, with a
descriptive type of research. Respondents in this study were 5
volunteers in Universitas Lambung Mangkurat. Data collection
techniques used were questionnaires with open questions. Data
analysis was done through the process of data reduction, data
presentation, drawing conclusions and verification. The results
showed that: 1) in terms of cooperation with lecturers, the
problems are not all lecturers prepared lecturing materials, the
lecturers did not understand the different abilities of students
with special need (SSN), 2) in terms of SSN, the problems are
limited sign language skills and frequent changes, SSN does not
want to be accompanied. 3) in terms of voluntary readiness, there
is no determination of the number of volunteers accompanying
SSN deaf, SSN assistance needs have not been identified so
volunteers are confused, voluntary attachments with disability
services have not been accounted for, and there are no
restrictions on services that volunteers must do to SSN.
Keywords—volunteers, a student with special needs (SSN),

MENGEMBANGKAN MOTIVASI BELAJAR MATEMATIKA PESERTA DIDIK SMA DENGAN PENERAPAN MODEL PEMBELAJARAN THINK TALK WRITE (TTW)
No full textHasil observasi di kelas menunjukkan bahwa hanya sedikit peserta didik yang: menyimak penjelasan yang disampaikan oleh guru, berusaha keras untuk menyelesaikan tugas matematika, aktif bertanya dan berdiskusi ketika menemukan kesulitan, dan mengumpulkan tugas tepat waktu pada saat proses pembelajaran matematika. Hal ini mengindikasikan peserta didik masih belum memiliki motivasi yang tinggi dalam mengikuti pembelajaran matematika dan akibatnya hasil belajar juga kurang maksimal. Usaha yang dilakukan untuk mengembangkan motivasi peserta didik diantaranya dengan menggunakan model pembelajaran Think Talk Write (TTW). Penelitian bertujuan untuk mengembangkan motivasi dan peningkatan hasil belajar peserta didik menggunakan model pembelajaran Think Talk Write (TTW) pada materi polinomial. Penelitian ini dilaksanakan menggunakan metode Penelitian Tindakan Kelas (PTK) dalam dua siklus, masing-masing siklus terdiri dari tiga kali pertemuan. Subjek penelitian adalah peserta didik kelas XI IPA 3 SMA Negeri 1 Banjarmasin tahun pelajaran 2018-2019 dengan jumlah 33 orang. Objek penelitian adalah motivasi dan hasil belajar peserta didik. Pengumpulan data melalui angket dan lembar observasi motivasi belajar peserta didik, serta tes evaluasi. Hasil penelitian menunjukkan bahwa terjadi pengembangan motivasi dan peningkatan hasil belajar matematika peserta didik dalam pembelajaran Think Talk Write (TTW)
