Date A point or period of time associated with an event in the lifecycle of the resource 2013-02-27 Description An account of the resource Hybrid PV-Grid menggabungkan dua sumber energi listrik yaitu grid (PLN) dan PV (Photovoltaics). Tegangan dari sumber PV sebesar 48 volt dc dinaikan dan diubah ke tegangan ac 280 volt dengan menggunakan konverter. Sedangkan sumber dari grid dijadikan sebagaiinfinite bus. Konverter terdiri dari konverter dc ke dc jenis forward konverter full-bridge dan inverter jenis SPWM. Sinyal SPWM dihasilkan dengan metode pembanding, frekuensi switching 50kHz, sedangkan sinyal PWM untuk konverter dc ke dc dan sistem kontroler menggunakan mikrokontroler PIC 16F877. Keluaran inverter terhubung ke busbar ac menghasilkan gelombang sinusoidal dengan frekuensi 50Hz dan arus maksimum 1,33A, sedangkan tegangannya mengikuti tegangan grid. Bila beban menyerap arus melebihi dari 1,33A maka kekurangannya akan disuplai dari grid.

Layout 1-stage pipeline consists of 3 units : op-amp, switch capacitor, precision comparator with latch. Pipeline ADC works gradually and requires synchronization of digital output 8 stage by using a unit delay circuit (D-FF). Pipeline ADC requires pulse rate (clock) generator to support its work. Units OP-AMP transconductance CMOS components designed with the correct specification ADC applications with capacitive loads, with a large input impedance and minimize noise. The precision comparator has Vos (offset voltage) approximately equal to 0V. The capacitor switch designs use NMOS switch as a switch for the sampling and multiplying. In the sampling phase and multiplying processes, the ADC requires a clock pulse with a non-intersect mode (lapping). The width of non-overlapping period was adjusted to the time of constance in the sampling process and multiplying. The total number of each pulse period equal to 12.5 ns or equal to the frequency of 80MHz. In the 1-stage layout an additional correction capacitor was required to correct residual voltage. The total area of the layout 1-stage pipeline ADC is 1-bit 200 μm x 98μm.

The research towards increasing palm oil quality has received a great priority in compliance with high attentions for consumers to health and economic value of vegetable oil. The objective of experiment is to obtain specific primer and generate partial fragment gene having a role of increment in beta carotene biosynthesis of oil palm. Application of biomolecular technique in plant genetic engineering is believed to be able to accelerate the genetic gain. An effort to manipulate of carotene composition is basically modification in its biosynthetic enzymatic pathway. The approach primer designing PRIMER3 software was able to generate couple of primer Beta-F and Beta-R and produce fragment  of lycopene β-cyclase (578 bp). Success in construction of complete functional gene will be a base of creating oil palm varieties with improved palm oil quality in future.

Kecepatan angin yang tidak stabil mengakibatkan tegangan yang dihasilkan oleh generator tidak stabil sehingga berpengaruh terhadap umur baterai. Dalam pengisian baterai, hal yang mendasar adalah bagaimana mengatur proses pengisian baterai sesuai dengan karakteristik pengisian baterai, sedangkan karakteristik baterai adalah non-linier, sehingga dibutuhkan rangkaian yang dapat mengontrol proses pengisian dengan baik. Pada penelitian ini menggunakan dua buah baterai 12 V/ 7,2 Ah. Rangkaian kendali akan mengatur switching antara pengisian dan pemakaian energi baterai. Switching akan bekerja berdasarkan besar tegangan pada baterai. Pada saat baterai penuh, besar tegangan pada baterai sebesar 12,5 V sedangkan pada saat baterai kosong tegangan baterai sebesar 10,5 V. Keseluruhan fungsi ini tertanam pada sebuah mikrokontroler ATmega32.

The wind speed which is not stable can cause a voltage resulted by an unstable generator so that it influences on the battery age. In charging a battery, the basic principle was that how the battery charging was regulated as the characteristics of battery charging. Meanwhile, the characteristic battery was non linear, so that circuit was needed in order to control a good process of charging. The research used two batteries of 12 V/ 7,2 Ah. The circuit control would organize the switching between charging and discharging a battery energy. The switching would work based on the voltage on the battery power. When the battery was full, the voltage of battery was for 12,5 V while the battery was empty, the voltage was for 10,5 V. The whole of this function was run on the microcontroller ATmega32.Key words: Wind Power Plant, Renewable Energy, Electric Power, IC Regulator LM7815, ATmega32 Identifier An unambiguous reference to the resource within a given context http://etd.unsyiah.ac.id//index.php?p=show_detail&id=6692 Title A name given to the resource DESAIN RANGKAIAN KENDALI PENGISIAN DAN PEMAKAIAN ENERGI BATERAI PADA PEMBANGKIT LISTRIK TENAGA BAYU (PLTB) BERBASIS MIKROKONTROLER ATMEGA32 Dublin Core The Dublin Core metadata element set is common to all Omeka records, including items, files, and collections.

Namun sistem ini memiliki kekurangan, salah satunya pada jam sibuk kendaraan harus menunggu lama disalah satu jalur. Sehingga diperlukan suatu sistem kontrol traffic light yang dapat memprioritaskan jalur yang lebih padat kendaraan Kontrol traffic light adaptif bekerja dengan mendeteksi jumlah antrian kendaraan pada sebuah jalur. Sistem ini bekerja dengan sensor yang mendeteksi panjang antrian kendaraan. Terdapat tiga sensor yang akan mendeteksi panjang antrian kendaraan pada setiap jalur. Jika antrian kendaraan mencapai sensor pertama maka waktu yang diberikan pada lampu hijau adalah 5 detik lebih lama dari waktu normal pada jalur tersebut. Jika antrian kendaraan mencapai sensor kedua maka waktu yang diberikan pada lampu hijau adalah 10 detik lebih lama dari waktu normal dan jika antrian kedaraan telah mencapai sensor ketiga sistem akan memberikan waktu nyala lampu hijau sangat lama yaitu 15 detik lebih lama dari waktu normal. Pada sistem kontrol traffic light adaptif ini terdapat dua buah sensor kemacetan yang diletakkan pada pertengahan jalur simpang empat yang akan menghidupkan seluruh lampu merah jika terjadi hal tidak terduga seperti mati lampu.
