PENGARUH GARAM TERHADAP PARAMETER VAN’T HOFF PADA PERSAMAAN KENAIKAN TITIK DIDIH
No full textIn the equation to determine the boiling point rise , Van\u27t Hoff parameter is used. However the parameters can only be used for dilute solutions. For this reason, it is necessary to do experiment to determine but for concentrated dilution. A mathematical : k = a.exp (b.m) is used to find the parameter. One hundred mililiter distilled water is added into beaker, then NaCl is also added to form NaCl solution of 0,25 molal. was added to water to form a 0.25 molal Na Solution is heated until boil and the boiling temperature n recorded. The experiment are conducted for different molality and type pf salt. The experimen shows that boiling point are influenced by strong/weak acid and strong/weak base. Each type of salt produce parameter different. The value of constante a is 0,853 to 3,707 and constante b is -0.16 to -0.42 with errata average above 10%
Perancangan dan Realisasi Audiometri Nada Murni
Full text linkTelah dibuat perangkat Audiometri Nada Murni dengan range frekuensi 250 Hz, 500 Hz sampai 8000 Hz (interval. 1000 Hz) dan range intensitas dari 30 dB sampai dengan 80 dB (interval 5 dB).
Alat ini terdiri dari Muliivibrator sebagai petnbangkit frekuensi, amplifier sebagai penguat frekuenSi dan loud speaker.
Alat ini telah dapat digunakan untuk mengukur ambang pendengaran dan sepuluh °rang sebagai sampel. Dengan nilai ambang pendengaran 30 dB. It has been made an audiometric device. The pure tone with frequency range of 250 Hz to 8000 Hz and intensity range of 30 to 80 dB ( 5 dB interval ).
This device consists of a multivibrator as the frequency generator, an amplifier as the voltage amplifier and a loudspeaker as the sound transducer.
This device has been capable to be utilized to measure the hearing threshold 30 dB of 10 persons as the samples
PENGEMBANGAN SITU GADOG, KELURAHAN CISALAK PASAR, KECAMATAN CIMANGGIS, KODYA DEPOK DAN SITU PENGARENGAN KELURAHAN CISALAK, KECAMATAN SUKMAJAYA, KOTA DEPOK
Full text linkKegiatan Pengabdian kepada Masyarakatini adalah suatu kerjasama antara UKI
dan Kodam V Jaya, berdasarkan permintaan dari KODAM V Jaya. Kegiatan ini juga
dilatarbelakangi oleh tugas KODAM V Jaya membenahi Situ-Situ didalam dan
sekitar Jakarta. Berdasarkan informasi dari Bapak Kolonel. Inf.Jacky, Asisten
Territorial KODAM V Jaya, KODAM V Jaya selalu mengajak Universitas dalam
pengembangan sosial daerah-daerah yang mereka benahi. Dalam hal ini KODAM V
Jaya memperbaiki Situ dan wilayah sekitarnya berdasarkan rencana dari Dinas
Pengairan,yang berada dibawah Dirjen PUPR, Kementerian Pekerjaan Umum.
Untuk itu KODAM V Jaya mengajak UKI dalam bentuk kegiatan Pengabdian kepada
Masyarakat (PkM)
