Abstract

Energy surya yang merupakan salah satu sumber energy terbarukan yang dapat dijadikan sebagai alternatif yang fleksibel digunakan untuk penyediaan listrik di Indonesia. Daerah Lampung memiliki potensi energi surya rata-rata 4,43 kWh/m2/hari dengan variasi bulanan sekitar 7 persen. Lampung juga dinyatakan cocok untuk aplikasi teknologi energi surya fotovoltaik karena memiliki karakteristik komponen radiasi langsung yang lebih dominan daripada komponen radiasi baurnya. Institut Teknologi Sumatra (ITERA) dalam perkembangannya sangat membutuhkan peningkatan pasokan energi listrik setiap tahunnya. Sehingga perlu lirikan akan energi lain sebagai dukungan dalam mewujudkan forest kampus dan pemenuhan energi. Untuk mengetahui potensi energy surya di lingkungan ITERA, maka dilakukanlah study awal energy surya yang dapat diproduksi. Tujuannya adalah agar didapat informasi potensi yang real untuk perkiraan pengembangan energy surya di lingkungan Institut. Pengukuran potensi ini menggunakan rangkaian panel surya yang disambung ke beban Resistor dan lampu yang diatur maksimum. Kemudian dihitung nilai Daya yang didapat dari pengukuran arus dan tegangannya. Dari hasil pengukuran diperoleh bahwa intensitas sinar matahari tinggi terjadi pada pukul 09.00-15.00 dengan daya luaran mencapai 109W.

Abstract

Infrastructure development is one of the important and vital aspect in order to accelerating the process of regional development. Infrastructure is also give an impact in improving the economy, accessibility, community development and the quality of human life. But, infrastructure development can’t be done simultaneously. Kabupaten Lampung Barat was designated by government as disadvantaged areas because of the lack on providing the infrastructure. Therefore, by using the analytical hierarchy process (AHP) this study is trying to find out the most important factor that affect the infrastructure development and the order of priority development of the five infrastructure in Kabupaten Lampung Barat, the infrastructure is: Roads, Drainage, Waste, Waste Water, and transportation. The AHP method revealed that the funding factor with the weight values 0,361, is the most important indicator that affect the infrastructure development in the study area. While, for the infrastructure, the AHP method revealed that roads infrastructure with weight values 0, 42, is the infrastructure which should be prioritized. Based on these result, the priority development of infrastructure in Kabupaten Lampung Barat is the provision of road infrastructure by increasing the capacity of the road and other road several indicators such as mobility and safety aspects

Abstract

Management of feedlot manure is becoming a larger responsibility as more regulations are imposed to protect water, both surface and groundwater, from manure contamination. Instead of using the manure for compost, feedlot owners can capture methane from the decomposing manure (and turn that into electricity or heat), or use the waste to produce liquid fuel. Biogas may also be called renewable natural gas because biogas can be used as a fuel source to produce electricity and heat like natural gas.This research converting energy generated from the measurement of total waste theoretically to be convert to electricity generated from the waste. Within the number of 19,398 total cows in Jati Agung Sub District husbandry has the potential to produce electric energy of 149,365.376 kwh per day or 15,836.79 mwh per year. The conversion from waste to electricity will reduce the number of total emission of 64,086.7464 tCO2 per year.

Abstract

Crisis period of Raung Volcano, located in East of Java, Indonesia, was started in November 2014. The seismicity of Raung Volcano was dominated by volcanic tremor. Volcanic tremor can be related with internal process of a volcano and can be a fruitful tool to understand the physical process inside the volcano. The intensity of tremor event in early crisis period is low but increases quickly then followed by the continuous tremor in the next month, December 2014. The dominant frequency of Raung volcano has range 1 ± 0,2 Hz. We suggest that there are two resonators exciting tremor signal based on the number of peaks in Raung’s tremor spectrum.

Abstract

Kami melakukan kajian teoretis mengenai reaksi hidrogenasi metoksida (H3CO) menjadi metanol (CH3OH) pada katalis klaster Pd6Ni secara teoretis menggunakan perhitungan berbasis teori fungsional kerapatan (DFT). Reaksi ini merupakan salah satu reaksi pembatas laju pada proses konversi gas karbon dioksida (CO2) menjadi metanol. Hasil perhitungan kami menunjukkan bahwa reaksi hidrogenasi metoksida pada katalis klaster Pd6Ni memiliki energi aktivasi yang lebih baik dibandingkan dengan energi aktivasi pada katalis konvensional berbasis permukaan Cu. Hal ini disebabkan karena klaster Pd6Ni mampu menstabilkan adsorpsi molekul metanol dengan baik dan memiliki energi adsorpsi *H yang relatif lemah.

Abstract

Phaleria (Phaleria macrocarpa Boerl.) contains flavonoids with antioxidants to prevent free radical that can cause cancer. This study aimed to determine the effect of drying temperature in spray dryer on the physical properties and antioxidant activity of the tablet from mahkota dewa fruit extract. Extraction process was performed by percolation technique with ethanol 70%. Extracts were made into powder using a spray dryer with a variation of drying temperature. The tablets were produced by direct compression method then the physical properties of powder, tablets physical properties and antioxidant activity were tested. Based on the results, the tablet with drying temperature of 70°C produced 6.9 ± 0.52 kg hardness, 7.38 ± 0.21 minutes disintegration time and 6.80 ± 2.85 %EDA. Tablet with drying temperature of 90°C produced 7.55 ± 0.35 kg hardness, 7.37 ± 0.11 minutes disintegration time, and 3.68 ± 0.73 %EDA. Tablet with drying temperature of 110°C produced 8.33 ± 0.21 kg hardness, 8.49 ± 0.08 minutes disintegration time, and 1.84 ± 0.87 %EDA. The results of this research showed that the increasingly of spray dryer temperature effect on the higher of tablet hardness and disintegration time, also decrease the anti oxcidant activity (p < 0.05).

Abstract

One of the problems on current road infrastructure development in Indonesia is the difficulty of getting road data information, for example is data for supporting sustainable road infrastructure development. Moreover, some of road authority did not realize that data is important element in the cycle process of road infrastructure development. Inaccurate road data will decrease the quality of road budgeting and programming, on the other hand it will affect the period service of road itself. The good road data could support sustainable road by providing the road value such as historical, current condition, and prediction. Indonesian Road Data Center Operations (IRODCO) is a concept of integrated road database storage. Collaborate data from Indonesian road authority (Ministry of Public Work and Housing, Ministry of Transportation, National Police and Local Government) can be stored, processed and managed to be a value- added information. IRODCO will provide various information, completely, easily and quickly for supporting the sustainable development of road infrastructure. This paper will explain the background of IRODCO concept, type of road database, the architecture, and how this concept will be implementing in Indonesia next, particularly for supporting the sustainable road infrastructure development.
