Abstract

[Computation and modeling] The current solar cell technology is a technology developed by a process that is cheaper and easier in manufacturing. The solar cells sensitized by a dye below abbreviated writing that the DSSC is often also called Grätzel cells or whether the writing in Indonesian to be Sel Surya Berbasis Pewarna Tersensitisasi (SSPT). DSSC is a potential candidate in as a third generation of solar cells (coming soon) because it does not require a material with a high degree of purity so that a low-cost production process. Dye used as a sensitizer can be either synthetic or natural. Metal-based organic dye complex ruthenium using synthetic (it is expensive), but it contains heavy metals that harm the environment. To reduce the cost of DSSC develops organic based on material sensitizer. DSSC using the same principles for the process of photosynthesis that behave as a chlorophyll dye that absorbs light and produces carrier.The effectiveness of DSSC is no doubt that reaching more than 10% but with using this expensive type which is ruthenium complex metal-based organic. It is necessary to study massive research, a material awareness survey that has good performance, environmental costs. In this study will be carried out using DSSC senduduk fruit dye (Melastoma malabathricum) manufacturing and oxide semiconductors are nano materials (nanocrystals) TiO2 anatase gradually the solvotermal techniques.

Transition electron in the QD be significant exceed thermal energy and cannot inducted by the fonon thermally while transition hole be simply inducted by the phonon acoustik thermal.Method of this research are concept and computation for accounting energy level. The concept which be used is DEK. The thickness well 𝐿𝑤 is small enough (10𝑛𝑚 or less), the set of level energy discret will be in the well and have hinges at the effective mass and the well thickness i.e 𝐸𝑛 rising with reduction 𝑚∗ or 𝐿𝑤. Maximum energy 𝐸1 = 3,77 × 104𝑒𝑉 at the thickness layer 𝐿𝑤 = 0,1𝑛𝑚. Maximum energy 𝐸2 = 1,51 × 105𝑒𝑉 at the 𝐿𝑤 = 0,1𝑛𝑚. ∆𝐸 is difference magnitude energy in the starting point 0,1𝑛𝑚 i.e 1,13 × 105𝑒𝑉 and in the last thickness QW i.e 10𝑛𝑚 is 1,13 × 101𝑒𝑉. Therefore transition electron in the QW be significantly exceed thermal energy and cannot inducted by the phonon thermal.

Abstract

ABSTRACT Determination of compounds and temperature modeling during heating of limestone have been carried out to obtain pure CaO from Papua limestone. . The purpose of this research is to determine the compounds, morphology and characteristics of each element and molecule present in limestone from Papua and to simply model the optimum temperature to obtain CaO. From the results of XRF testing, there is one main element that contains the most chemical elements in the limestone sample from black soil (sample 1) and perumnas three (sample 2), namely Ca (calcium) with weight percent 99.57 and 99.69. XRD results are also supported from characterization with EDS where the dominant elements of sample 1 are O, Ca and Mg in sample 2 dominant elements Ca, O and C. Then based on SEM analysis, the morphology of CaMg (CO3) 2, Ca (Co3) and MgCa ( Co3) resembles a cube but the particle size is uneven and irregular due to impurities. The temperature obtained based on the results of this calculation is 12800C.

Abstract

The Acai River functions as a primary channel located in the middle of Abepura City, which ends downstream at Yotefa Bay. The presence of various anthropogenic activities can provide a pollution burden to the environment, one of which is the decline in river water quality. This study aims to determine the water quality of the Acai River in Jayapura City. The study was conducted by collecting data through surveys and taking river water samples at six points. The parameters studied included temperature, water color, pH, TDS, DHL, BOD, and COD. The results of the study showed that the concentrations that exceeded the class II water quality standard limits, namely the BOD and COD concentrations at stations 1, 2, 3, 4, 5, and 6 exceeded the quality standard limits. Based on the Pollution Index value, at stations 1, 2, 3 the conditions were lightly polluted, while the conditions at stations 4, 5, 6 were classified as moderately polluted. It can be concluded that from upstream to downstream the water quality of the Acai River has increased in its water quality parameters
