Abstract

Automation system waterwheel for farmed shrimp respiration have realized using dissolved oxygen sensors (DO). The DO sensor used to detect the levels of dissolved oxygen in the water. Digital data output sensor DO is connected to the computer via the arduino uno, furthermore the output data are recorded and displayed on the LCD monitor and a television series. Automation system using relay with a range of dissolved oxygen levels <4,00 mg/L for the condition of the windmills ON and >5,50 mg/L for the condition of the windmills OFF.

Abstract

Telah direalisasikan sitem elektrolit berbasis air laut dengan penambahan variasi Alumina. Penelitian ini bertujuan untuk mengetahui alumina terhadap karakteristik tegangan dan arus yang dihasilkan. Variasi alumina yang digunakan yaitu sebanyak 2 gram dan 4 gram. Proses pengujian dilakukan menggunakan 40 buah sel elektrolit dengan sepasang Zn dalam tiap selnya. Waktu pengujian dilakukan selama 48 jam dengan pergantian elektrolit sebanyak 2 kali untuk tiap variasi alumina. Hasil pengujian relatif sama yaitu menghasilkan tegangan sebesar 26,9 volt elektroda Cu-dan arus sebesar 2,5 mA untuk tiap variasi alumina, sehingga diketahui bahwa alumina yang di berikan tidak memberikan perubahan yang signifikan terhadap hasil tegangan, dan arus.

Abstract

The measuring instrument of rainfall with weightscale system using phptotransistor NPN type, designed for measuring the value of rainfall wich fell down with using LED light. The instrument designed using data processor Arduino Uno, timer DS1307, and micro SD The testing instrument was do in BMKG Bandara Radin Inten II South of Lampung. The analog data has results by phototransistor will be processed by Arduino Uno and the results data of rianfall  which  saved in the micro secure digital and  displayed by the Liuquid Crystal Dislay (LCD) with delay 1 second. The control system instrument using a valve solenoid with volume reference 500 ml. The instrument resolution has results was equal 0,19 mm and the instrument capable to read the minimum of vilume change up to 2 ml. Avarage of error from measuring instrument was equal to 5,7 %.

Abstract

The electrical characteristics of river  water, brackish water, swamp water, spring water, and rain water can be determined by using electrodes. The electrode pairs of this research are Cu-Zn and C-Zn electrode.  The electrical characteristics measurement of river water, brackish water, swamp water, spring water, and rain water are connected with a 1,2watt LED load and without load. The electrolyte cell consisted of 20 cell, which were arranged in series with a volume of ±200 ml per cell. The maximum current (I) which were produced by Cu-Zn electrode using brackish water is 1,58 mA;  river water is 0,8 mA; swamp water is 0,57 mA;spring water is 0,21 mA; and rain water is 0,01 mA. Meanwhile The maximum current (I) which were produced by C-Zn electrode using brackish water is 1,54 mA;  river water is 0,01 mA; swamp water is 0,8 mA;spring water is 0,26 mA; and rain water is 0,09 mA. The type of water that has the best electrical characteristic are brackish water with light intensity of 1192 lux and river water with light intensity of 121 lux.

Abstract

It has been designed and realized a rain meter type weighing bucket, this device by raining volume grader type weighing bucket, utilizing timbangan's principle with spiral spring. potentiometer that is strung up on spiral spring axis have output as changed as interference which its point in proportion to length increase of system. Raining volume to be gotten by weighs rainwater mass with permanence water type mass as big as 1 kg / liter therefore water mass point already been weighed one par with appreciative volumed rainwater. Measurement and count result already been measured and is read on mikrokontroler will thru feature LCD 16x2 and is kept on micro sd .  Data that is taken as big as 20 kb in the period of 1 downloading hours. Quick its slowing inlay on penampung's container regarded by rain Intensity. gotten by measurement deviation (Deviation default) as big as 0,4 until 0,44 liters. With raining average that is taken up to 1 hour is 0.5 liter or one par with 0.5 kg water mass.

Abstract

Penelitian dan publikasi ilmiah guru merupakan bagian dari penilaian kompetensi guru. Sehingga pembinaan dan bimbingan terhadap guru untuk dapat melakukan penelitian dan pubikasi ilmiah sangat diperlukan. Karena secara umum semua guru memiliki kemampuan untuk melakukan penelitian dan publikasi ilmiah. Tujuan kegiatan adalah memberikan pengetahuan kepada guru dalam melakukan penelitian, baik penelitian tindakan kelas (PTK) maupun penelitian konten bidang ilmu dilanjutkan dengan publikasi ilmiah hasil penelitiannya. Metode pelaksanaan kegiatan meliputi: tes awal, pemaparan materi (ceramah dilengkapi dengan praktek yang diikuti peserta), dan tes akhir. Pelaksanaan kegiatan dilakukan selama satu hari, bertempat di SMPN 1 Metro. Kegiatan diikuti oleh oleh 28 orang, terdiri atas guru SMP negeri dan swasta Kota Metro. Hasil tes awal menggambarkan pengetahuan guru terhadap penelitian dan publikasi ilmiah masih rendah, yaitu nilai terendah 11, tertinggi 30, dan rata-rata 29. Sedangkan hasil tes akhir diperoleh nilai terendah 39, tertinggi 67, dan rata-rata 52. Hasil tes akhir menunjukkan peningkatan pemahaman guru yang ditunjukkan melalui peningkatan nilai tes akhir yaitu nilai terendah meningkat 167%, nilai tertinggi meningkat 71 %, dan rata-rata meningkat 81 %..
