  • BIOMIMETIC PHOTODIODE DEVICE WITH LARGE PHOTOCURRENT RESPONSE USING
           PHOTOSYNTHETIC PIGMENT-PROTEIN COMPLEXES

    • Authors: Damar Yoga Kusuma, Hariyadi Soetedjo
      Pages: 1 - 6
      Abstract: Efficient light to energy conversion was demonstrated in solid-state, lateral photodiodes device containing photosynthetic light-harvesting chlorophyll protein complexes as active materials. The device exhibits the highest reported photocurrent density response of 365 µA/cm2 when illuminated at 320 mW/cm2 radiation source power. The photocurrent response was stabled over 104 s of continuous cycles of dark and illumination states. The short rise and decay time of the photocurrent waveform within sub-second range indicates an effective photogeneration and charge extraction within the device. Optical bandgap extraction using absorption coefficient method reveals that the energy gap of the active materials ranges from 2.8 to 3.8 eV, correspond to the Photosystem I and Photosystem II of the photosynthetic pigment-protein complexes.

  • THERMOACOUSTIC REFRIGERATOR SYSTEM PERFORMANCE USING THE PVC (POLYVINYL
           CHLORIDE) STACK BY POWER INPUT VARIATION

    • Authors: Indah Kharismawati
      Pages: 7 - 13
      Abstract: The thermoacoustic refrigerator is an innovative alternative and did not use substances that had a negative impact on the environment such as freon, but using air as the working substance. The materials used the refrigerator were easily obtained and the construction components were simple so that made this refrigerator was cheap, easy to make and easy to maintain. Stack was used in the thermoacoustic refrigerator system used PVC (Polyvinyl chloride) which is parallel cylindrical shape and diameter (1.50 ± 0.05) mm and length of 8 cm. Variations of loudspeaker input power that used were 20 watt, 30 watt, 40 watt, 50 watt and 60 watt. Variations of the input power that used to determine the effect of loudspeaker input power to decreasing temperature in the operating of the thermoacoustic refrigerator system using  PVC stack. From the result, loudspeaker input power influenced on the decreasing temperature that was 6.0 °C for 20 watts, 6.7 °C for 30 watts, 7.2 °C for 40 watts, 8.0 °C for 50 watts and 9.0 °C for 60 watts. From these results indicated optimum decreasing temperature depended on the amount of loudspeaker power that was directly proportional to the decreasing temperature obtained.

  • APPLICATION OF CONTROLLED SOURCE AUDIO MAGNETOTELLURIC (CSAMT) AT
           GEOTHERMAL

    • Authors: Susilawati S.
      Pages: 14 - 19
      Abstract: CSAMT or Controlled Source Audio-Magnetotelluric is one of the Geophysics methods to determine the resistivity of rock under earth surface. CSAMT method utilizes artificial stream and injected into the ground, the frequency of artificial sources ranging from 0.1 Hz to 10 kHz, CSAMT data source effect correction is inverted. From the inversion results showed that there is a layer having resistivity values ranged between 2.5 Ω.m – 15 Ω.m, which is interpreted that the layer is clay.

  • Hypocenter determination of volcano-tectonic earthquake, Gede Volcano,
           January – November 2015 period

    • Authors: Aulia Kharisma Nugraha, Sukir Maryanto, Hetty Triastuty
      Pages: 20 - 26
      Abstract: Gede volcano is an active volcano in West Java, Indonesia.  Research about determination the volcano-tectonic earthquake source positions has given results. Research data used are volcano-tectonic earthquakes from January until November 2015.Characteristics of volcano-tectonic earthquakes obtained after the data was selected. They consist deep (VT-A) and shallow earthquake (VT-B and LF). Their frequency range each of them are VT-A between 5 - 15 Hz, VT-B between 3-5 Hz, and LF between 1-3 Hz. Gede volcano activity during this period was dominated by VT-B events. These evidenced by hypocenters are dominantly in shallow-depth earthquake source that between -2 - 2 km from mean sea level (MSL). Geiger’s Adaptive Damping (GAD) used for determining the hypocenter of volcano-tectonic (VT) events. In addition, the swarm of VT events was also obtained on 9 - 10 October 2105 with the emergence average 1 hour per event. From 100 events of volcano-tectonic, eleven of them including the earthquake swarm. These dominated by shallow earthquakes (VT-B and LF). Hypocenter distribution divided into four clusters. Cluster I located in the crater of Gede volcano dominated by VT-B earthquakes their depth range 2 km below MSL to 2 km above MSL.The seismic sources of cluster I dominant due to the release of fluid-gas in the conduit pipes. Cluster II located at the west of Gede volcano caused by Gede-Pangrango fault-line dominated by VT-A earthquakes with depths range 1.5 km below MSL to 700 m above MSL. Cluster III: located on the North of Gede volcano dominated by VT-A events there caused by graben fault area with those depths range 7.5 – 1.65 km below MSL. Cluster IV located in South West of Gede volcano contained by VT-A earthquake at 10 km below MSL and VT-B earthquakes this depth 2 km below MSL. Seismic sources in Cluster IV due to magma intrusion filled into fractures caused by a fault in the West of Gede volcano. Degassing become a seismic source that dominates all volcano-tectonic events from January to November 2015.Although there still are deep seismic sources that caused by the intrusion and magma filling into fractures due to faults extends from North to South occur in the West of Gede volcano.

  • PENGGUNAAN BATANG KANTILEVER KUNINGAN SEBAGAI PENGUKURAN MASSA DENGAN
           MENGGUNAKAN SENSOR STRAIN GAUGE

    • Authors: Hena Dian Ayu, Akhmad Jufriadi, Kurriawan Budi Pranata, Endarko E., Melania Suweni Muntini
      Pages: 27 - 35
      Abstract: Telah dilakukan penelitian penggunaan batang kantilever kuningan sebagai pengukuran massa menggunakan sensor strain gauge 120 ohm. Penelitian ini pada dasarnya memanfaatkan gejala defleksi dari permukaan batang.  Gejala defleksi ini terjadi  akibat massa yang diletakkan pada salah satu ujung batang. Massa sebagai pembeban dikalibrasi dengan alat ukur massa standart menggunakan neraca OHAUS merk PioneerTM tipe PA214. Defleksi yang terjadi dideteksi sebagai strain oleh transduser strain gauge yang terpasang  pada permukaan batang kantilever yang sudah dikonversi dalam bentuk sinyal tegangan melalui suatu rangkaian elektronis jembatan Wheatstone tipe quarter dan penguat diferensial menggunakan IC AD521JD. Didapatkan persamaan karakteristik prototipe alat ukur massa yang menyatakan hubungan antara tegangan keluaran penguat differensial terhadap penambahan massa 0,1 gram yang dinyatakan dalam persamaan y = 0,2014x + 0,4064. Adapun persamaan karakteristik tegangan keluaran penguat diferensial terhadap pengurangan massa 0,1 gram dinyatakan dalam persamaan y = 0,2378 x + 0,1174. Sementara persamaan yang digunakan dalam konversi ADC didalam mikrokontroller menggunakan m = 4.794V  – 1.801 (gram). Sedangkan nilai massa yang terukur ditampilkan dalam LCD 2 × 16 dalam satuan gram.
