Abstract

The development of Semarang city requires the availability of water for daily use and industry in line with population growth. Uncontrolled use of water will damage the groundwater system. The purpose of this study was to determine the zone of the decrease of water level to obtain information about area that utilizes excess water. The method used is a micro-gravity vertical gradient between times. Gravity measurements were done at 124 points spread evenly between May and October 2013. The results showed that there was a decrease in ground water level in the Industries area Kaligawe, Tanah Mas, and Tlogosori which was identified with the vertical gradient anomaly of micro gravity between the times from May to October 2013. The regions which have high negative changes in ground water level (1.2-1.4 m / year) were the monitoring wells Madukoro 2, LIK Kaligawe and PT Aquaria which are the industrial areas. Exploitation of ground water in industrial areas is relatively high compared to the other regions.Perkembangan kota Semarang yang menuntut ketersediaan air untuk keperluan sehari-hari dan industri seiring dengan pertambahan jumlah penduduk. Pemanfaatan air yang tidak terkendali akan menyebabkan sistem  air tanah rusak. Tujuan penelitian ini adalah menentukan zona penurunan muka air tanah untuk memperoleh informasi daerah yang memanfaatkan air secara berlebihan. Metode yang digunakan adalah gradien vertikal gaya berat mikro antar waktu. Pengukuran gaya berat di lakukan di 124 titik yang tersebar merata pada periode Mei dan Oktober 2013. Hasil peneltian menunjukkan telah terjadi penurunan muka air tanah di lingkungan Industri Kecil Kaligawe, perumahan Tanah Mas, Perumahan Tlogosori yang ditandai dengan anomali gradien vertikal gaya berat mikro antar waktu Mei-Oktober 2013. Wilayah yang memiliki perubahan muka air tanah negative tinggi (1,2-1,4 m/tahun), berada di sekitar sumur pantau Madukoro 2, LIK Kaligawe dan PT Aquaria dimana tutupan lahan di sekitar sumur pantau tersebut merupakan kawasan industri. Eksploitasi air tanah pada kawasan industri relatif tinggi jika dibandingkan dengan kawasan lainnya.

Abstract

Research on utilization of rind extracts of red dragon fruit (hylocereus costaricensis) as sensitizer for dye sensitized solar cell (DSSC) has been conducted by reviewing influence of the concentration against the DSSC efficiency. Characterization on optical absorption at various concentrations and identification of functional groups, each using an UV-Vis spectrometer and Fourier transform infra red (FTIR), have done to the dye in the form of the extracts. The dye characterization result on optical absorption at various concentration shows that the optical absorption at range of wavelength 320-760 nm has the peak of absorbance tend to increase with increasing the concentration. Therefore the dye is capable to role as a sunlight absorber. Meanwhile, infra red absorption spectrum obtained from FTIR results indicate the presence of functional groups O-H, C=O, C=C, C-O, and C-H aromatic. Results of current-voltage characterization of DSSC show an increase in maximum power and efficiency with increasing concentration.Penelitian mengenai pemanfaatan ekstrak kulit buah naga merah (hylocereus costaricensis) sebagai penyensitif pada dye sensitized solar cell (DSSC) telah dilakukan dengan meninjau pengaruh konsentrasi ekstrak terhadap efisiensi DSSC. Terhadap dye berupa ekstrak kulit H. Costaricencis dilakukan pengujian serapan optik pada berbagai konsentrasi dan identifikasi gugus fungsi, masing-masing menggunakan spektrometer UV-Vis dan fourier transform infra red (FTIR). Hasil pengujian dye pada konsentrasi 100 %, 50 %, 33,33 %, 25%, dan 20% menunjukan serapan optik yang terjadi pada panjang gelombang 320-760 nm, memiliki puncak yang cenderung semakin tinggi seiring dengan peningkatan konsentrasi. Dye yang berasal dari ekstrak kulit H. Costaricensis ini mampu berperan sebagai sunlight absorber. Sementara itu, spektrum serapan infra red yang diperoleh dari hasil FTIR mengindikasikan adanya gugus fungsi O-H, C=O, C=C, C-O, dan C-H aromatik. Hasil karakterisasi arus-tegangan dari DSSC menunjukkan adanya peningkatan nilai daya maksimum dan efisiensi seiring peningkatan konsentrasi.
