Aktivitas Antibakteri Kombinasi Ekstrak Etanol Daun Sirih Merah (Piper crocatum Ruiz and Pav) Dan Kloramfenikol Terhadap Bakteri Salmonella typhi, Shigella dysenteriae, Dan Staphylococcus aureus Beserta Bioautografinya

Tanaman sirih merah telah diketahui dapat mengobati berbagai jenis penyakit dan dipercaya dapat digunakan sebagai antibakteri. Kloramfenikol merupakan antibiotik bakteriostatik berspektrum luas yang aktif terhadap mikroorganisme aerobik dan anaerobik, bakteri Gram positif maupun negatif. Tujuan dari penelitian ini adalah untuk mengetahui efek kombinasi ekstrak etanol daun sirih merah dan kloramfenikol terhadap bakteri Salmonella typhi, Shigella dysenteriae, dan Staphylococcus aureus. Uji aktivitas antibakteri menggunakan metode difusi (Kirby Bauer) dengan menentukan diameter zona hambat. Konsentrasi ekstrak etanol daun sirih merah yang digunakan 70% dan kloramfenikol 4% untuk bakteri Staphylococcus aureus dan Salmonella typhi serta 1% untuk Shigella dysenteriae dengan pelarut DMSO 100%. Kombinasi ekstrak etanol daun sirih merah : kloramfenikol dibuat tiga perbandingan volume yaitu: (25%:75%), (50%:50%), dan (75%:25%) dengan volume total 20 μL per disk. Hasil penelitian menunjukkan diameter zona hambat berturut-turut pada bakteri Staphylococcus aureus dengan perbandingan volume (25%:75%), (50%:50%), dan (75%:25%) sebesar 10 mm, 11 mm, dan 12 mm pada Salmonella typhi 10,3 mm, 12 mm, dan 14 mm pada Shigella dysenteriae 9,3 mm, 10,3 mm, dan 12 mm. Hasil analisis dengan anova didapatkan p-value statistik uji F pada Staphylococcus aureus 0,272 > 0,05 tidak signifikan sedangkan pada bakteri Salmonella typhi dan Shigella dysenteriae adalah 0,016 dan 0,001 < 0,05 terdapat perbedaan yang signifikan. Berdasarkan hasil identifikasi senyawa menggunakan kromatografi lapis tipis (KLT) dan uji bioautografi diketahui senyawa yang memiliki aktivitas antibakteri dari ekstrak etanol daun sirih merah adalah fenolik, terpenoid, dan alkaloid pada Staphylococcus aureus dan Shigella dysenteriae, serta senyawa terpenoid dan alkaloid pada Salmonella typhi

APLIKASI MK AT89C51 UNTUK PENDETEKSIAN KADAR LIMBAH MERUGIKAN INDUSTRI PENGEPAKAN UDANG

Tujuan pengembangan adalah merancang pendeteksi kadar STPP limbah industripengepakaan udang. Instrumentasi sistem menggunakan sistem fotometri memanfaatkansinar UV yang ditembakkan ke sampel limbah pada kuvet untuk mendeteksi kadar STPP.Logikanya semakin besar sinar UV yang diserap oleh STPP maka semakin besar kadarSTPP-nya. Sinyal cahaya dilewatkan pada cairan STPP dan diterima oleh photodiodaselanjutnya diubah menjadi sinyal listrik. Perubahan sinyal cahaya menjadi listrikdigunakan sebagai input OP-Amp yang berfungsi sebagai pengkondisi sinyal input ADC.Selanjutnya ADC akan mengubah tegangan input menjadi data digital 8 bit. Data yangdiinputkan ke MK akan diolah dengan program MCS-51 dan ditampilkan ke display sevensegment dan merupakan hasil pen-deteksian kadar STPP dalam persen. Hasil pendeteksianmempunyai keandalan ± 80%

Klasifikasi Jenis Biji Kopi dengan Menggunakan Metode Gray Level Co-occurrence Matrix (GLCM)

Kopi merupakan salah satu tanaman perkebunan yang menjadi sumber penghasilan rakyat dan juga dapat menjadi sumber peningkat devisa negara melalui ekspor biji kopi mentah maupun olahan dari biji kopi. Kopi dapat dibedakan berdasarkan jenisnya yaitu Kopi Robusta dan Kopi Arabika. Setiap varietas kopi memiliki harga yang berbeda-beda tergantung dari jenis varietasnya. Tidak semua petani, dan pemilik coffee shop mampu mengenali varietas kopi dengan hanya melihat green bean dan roasting. Hal tersebut dapat diatasi dengan pemodelan yang dapat mengidentifikasi varietas Kopi Robusta dan Arabika agar dapat digunakan sebagai second opinion untuk mengidentifikasi varietas kopi robusta dan arabika. Salah satu metode yang dapat digunakan adalah metode pencitraan. Tujuan dari penelitian ini adalah untuk mengetahui akurasi mengklasifikasikan jenis biji kopi dengan menggunakan metode Gray Level Co-occurrence Matrix (GLCM). Pada penelitian ini bahan utama yang digunakan adalah biji kopi jenis Robusta Tanggul dan Raung, serta Arabika Ijen dan Bali yang telah di sangrai. tingkat kematangan sangrai biji kopi yang digunakan pada penelitian ini adalah coklat muda (light roast) untuk jenis Arabika dan medium roast untuk jenis robusta. Hasil yang diperoleh dari akurasi klasifikasi jenis biji kopi dengan menggunakan metode GLCM sebesar 99% untuk klasifikasi tipe kernel atau powder, 93% untuk klasifikasi jenis Robusta atau Arabika, dan 56% untuk klasifikasi daerah asal yaitu (Tanggul, Raung, Ijen, dan Bali) dengan citra data uji sebanyak 80 citra
