The 2nd International Symposium On Applied Chemistry 2016 (ISAC 2016)

http://situs.opi.lipi.go.id/isac2016/

INTRODUCTION

After the last October in Bandung.
After a warm kinship that had been accompanied all over 250 participants from seven different countries in first symposium.
This year, International Symposium on Applied Chemistry (ISAC) 2016 is back with the same spirit.
ISAC 2016 will be held on 3-5 October 2016 at Indonesia Convention Exhibition (ICE), BSD City, Indonesia, by carrying the theme, “Chemistry for Better Life”.
This is the 2nd international scientific conference organized by Indonesian Chemical Society (HKI) and supported by Indonesian Institute of Sciences (LIPI).

ISAC 2016 will facilitates sharing of ideas and recent research experiences and its application in chemical related fields, as well as to promote international cooperation among participants. Researcher, lecturer, student, industrial practitioner and government agency members are welcomed to participate in this event as paper presenter participant or only enjoying the kinship among colleagues asnon paper presenter participant.

Perhitungan Ketidakpastian Pembuatan Standar Kalibrasi

Tujuan

Standar kalibrasi dipersiapkan dari logam kemurnian tinggi (cadmium) dengan konsentrasi 1000 mg/L

Prosedur pengukuran

Permukaan logam kemurnian tinggi dibersihkan untuk menghilangkan beberapa kontaminasi oksida logam. Setelah itu logam ditimbang dan kemudian dilarutkan dengan asam nitrat dalam labu ukur.

Perhitungan Ketidakpastian Titrasi Asam/Basa

Tujuan

Larutan HCl distandarisasi menggunakan larutan NaOH yang diketahui konsentrasinya.

Prosedur pengukuran

Larutan HCl dititrasi menggunakan larutan NaOH yang telah distandarisasi menggunakan KHP, untuk menentukan konsentrasinya.

Perhitungan Ketidakpastian Standarisasi Larutan NaOH

Tujuan

Larutan NaOH distandarisasi menggunakan standar KHP

Prosedur pengukuran

KHP dikeringkan dan ditimbang. Persiapkan larutan NaOH yang akan distandarisasi. KHP dilarutkan dan kemudian dititrasi menggunakan larutan NaOH
