Abstract

George Simon Ohm (1789-1854) merumuskan hubungan antara kuat aruslistrik (I), hambatan (R) dan beda potensial (V) yang kemudian dikenal dengan hukum Ohm. Hubungan antara tegangan, arus dan hambatan dalam rangkaian dinyataan oleh V = I.R persamaan disamping adalah hokum ohm. Dalam penelitian ini menggunakan metode eksperimen sebagian percobaan pengujian teori hokum ohm. Pada bagian hasil penelitian yang diperoleh melalui hasil uji simulasi menggunakan software proteus. Dari hasil percobaan dan perhitungan diatas bahwa hasil yang di dapat keduanya sama. Dari pengukuran dapat dianalisa sesuai dengan hokum ohm yaitu besarnya arus listrik berbanding terbalik dengan resistansi. Diketahui ketika variable tegangan naik dengan resistansi konstan maka arus juga naik, sebaliknya jika tegangan konstan dan variable resistansi naik maka arus semakin turun.

Abstract - Facts in the field show that many function generator instruments are composed of analog components. Based on the size of its dimensions, this type of function generator has a large size so that it cannot be implemented on small-scale devices. To optimize electronic devices, it is necessary to implement a digital system. Based on this, this research intends to produce a digital to analog converter-based digital function generator using AT-Mega16, LCD2x16 and DAC0808 to determine the frequency and waveform that can be measured directly using an oscilloscope. The use of the C programming language by utilizing the VSM Studio and ProgISP software as commands for AT-Mega16. This research produces a function generator with a frequency range of 30.53 Hz - 20 Khz. The resulting waveforms include sine, checkerboard and ramp/ sawtooth. The function generator is 100% accurate at a frequency of 33 Hz – 200 Hz and the measurement difference appears at a frequency of more than 200 Hz and tends to increase up to a frequency of 20 Khz. In addition to the difference in frequency, there are also waveform defects at frequencies above 2 Khz. Placement of DAC-based function generator oscillation programming commands in sub programs can cause waveform defects. The waveform defect is assumed to be the lag time of the microcontroller when it will perform looping of approximately 12.9 μs. This can add to the difference in the resulting period. The use of commands and variable readings in microcontroller programming requires a time lag so that the difference between the input period and the resulting period is 140 μs, this can be seen in the experimental measurement period from 50 μs to 500 μs. Keywords — Function Generator, Digital to Analog Converter, Microcontroller Abstrak— Fakta di lapangan menunjukkan bahwa instrumen function generator banyak yang tersusun atas komponen analog. Berdasarkan ukuran dimensinya function generator tipe tersebut memiliki ukuran besar sehingga tidak dapat diimplementasikan pada perangkat skala kecil. Untuk mengoptimalkan divice elektronik dibutuhkan implementasi sistem digital. Berdasarkan hal tersebut penelitian ini bermaksud menghasilkan function generator digital berbasis digital to analog converter dengan memanfaatkan AT-Mega16, LCD2x16 dan DAC0808 untuk mengetahui frekuensi dan bentuk gelombang yang dapat diukur secara langsung dengan menggunakan oscilloscope. Penggunan bahasa pemrogaman C dengan memanfaatkan software VSM Studio dan ProgISP sebagai perintah untuk AT-Mega16. Penelitian ini menghasilkan function generator dengan range frekuensi 30,53 Hz - 20 KHz. Bentuk gelombang yang dihasilkan antara lain sinus, kotak-kotak dan ramp/ gigi gergaji. Function generator akurat 100% pada frekuensi 33 Hz – 200 Hz dan muncul selisih pengukuran pada frekuensi lebih dari 200Hz dan cenderung naik sampai pada frekuensi 20 KHz. Selain selisih frekuensi juga terdapat cacat bentuk gelombang pada frekuensi diatas 2 KHz. Penempatan perintah pemrograman osilasi function generator berbasis DAC pada sub progam dapat menyebabkan cacat bentuk gelombang. Cacat bentuk gelombang tersebut diasumsikan sebagai jeda waktu microcontroller ketika akan melakukan looping sebesar kurang lebih 12,9 μs. Hal tersebut dapat menambah selisih periode yang dihasilkan. Penggunaan perintah-perintah dan pembacaan variabel pada pemrograman microcontroller membutuhkan jeda waktu sehingga didapatkan selisih antara periode yang diinput dengan periode yang dihasilkan sebesar 140 μs hal tersebut terlihat pada percobaan pengukuran periode 50 μs sampai dengan periode 500 μs.

Abstract

De-Djawatan Tourism Destinations are known by various tourists both local and non-local with their natural beauty in the form of large and lush trees that are still beautiful or natural. De-Djawatan tourism does not yet have detailed information either manually or digitally related to the biological and general classification of plants in that location. As smartphone technology develops, the information needed to be very easy to obtain. QR Code is one method to obtain complete information. QR Code is a type of two-dimensional image that displays data in the form of text. This community partnership program aims to provide appropriate technology in the form of the QR code method in determining the identification of plants found in De-Djawatan tourist destinations. This aims to make it easier for tourists to find information on various plants both biologically and in general. The stages of program implementation start from the observation stage, media creation, and implementation. The results of this program using the QR Code can include the identity of the identification results of plants, such as division, order, family, genus and species of plants in the De-Djawatan location. In this QR Code method there are features such as Home, Collection, and Admin. Before the QR Code is created, the document data is encrypted and then used as a QR Code. The result of scanning the QR Code is in the form of a Uniform Resource Locator (URL) that points to the document data. When the URL is executed on the web browser, the system performs a description of the URL, then it is matched with the database, and then displayed to the web browser. The final result is a Document Validation application in the form of a QR Code which is used to convey plant identification information, such as division, order, family, genus and species of plants.

Abstract

Innovation is needed using alternative ingredients as natural larvacide instead of temefos. One of the plants that can be used for making natural larvacide is Moringa (Moringa oleifera) which contains alkaloids and flavonoids. This study aims to determine the effect of the type of solvent on Moringa (M. oleifera) extract on the mortality of Aedes aegypti larvae and determine the most effective solvent in extracting Moringa leaves as A. aegypti larvacide. This study uses a completely randomized design with 5 replications. Moringa leaf extract is obtained by maceration with aquades, ethanol, methanol, ethyl acetate, and n-hexane. Moringa leaf extracts were tested for phytochemistry and larvacidal power was tested for A. aegypti larvae. Mortality data were analyzed by ANOVA and Tukey tests. The results showed that the type of solvent in moringa leaf extract (M. oleifera) did not significantly influence the mortality of A. aegypti larvae and the most effective type of solvent for extraction of Moringa leaves were aquades and ethanol. Based on the research findings it can be concluded that the type of solvent in moringa leaf extract does not significantly influence the mortality of A. aegypti larvae. However, the most effective types of solvents for extraction of Moringa leaves are aquades and ethanol.
