Studi Identifikasi Pengelolaan Air Limbah Domestik Di Kecamatan Mijen, Gunungpati, Gajahmungkur Dan Semarang Selatan Kota Semarang

Sanitation refers to the hygienic and proper management, collection, disposal or reuse of human excreta (feces and urine) and community liquid wastes to safeguard the health of individuals and communities. Sanitation have three primary objectives:Improving health conditions, promoting dignity of living or enhanced quality of life, and protecting the environment. The combined positive effects of these conditions lead to wider economic benefit. One of sanitation component is domestic wastewater which is in fact haven't use the proper management . Proper management can be decided by assessing current situation (sourced by primary and secondary data), gap analysis based on three aspects which is institutional aspects, technical aspects, financing aspects, legal aspects and community participation. This study identification focused on determining domestic wastewater processing system based on population density, the area physical condition, the source of water used, and the ability to finance. Whereas scope area of this identification study is Mijen, Gunungpati, Gajahmungkur and South Semarang at Semarang city. Mijen and Gunungpati has similarity at population density which is less than 150 people per ha and the area physical condition such as high permeability, ground water depth >50 meters, dominated by 2-15% slope, and also from the financial side that range income level 1,5-3 million rupiah is still suitable for septic tank as it's technology an on site system as its alternative system. In the other side, Gajahmungkur and South Semarang also has similarity at water used sourced which is 72% and 75% respondent use PDAM as primary source and generally has middle class of permeability. Both of this sub district also has population density more than 150 people per ha and the area dominated by 2-15% slope range which is all of those factor suitable for sewerage conventional as its technology.This study help the reader to make informed about the proper prossesing system of each study area and furthermore to achieve sanitation primary objectives

Transition of D- Level Quantum Systems Through Quantum Channels with Correlated Noise

Entanglement and entanglement-assisted are useful resources to enhance the mutual information of the Pauli channels, when the noise on consecutive uses of the channel has some partial correlations. In this Paper, we study quantum-communication channels in $d$-dimensional systems and derive the mutual information of the quantum channels for maximally entangled states and product states coding with correlated noise. Then, we compare fidelity between these states. Our results show that there exists a certain fidelity memory threshold which depends on the dimension of the Hilbert space $(d)$ and the properties of noisy channels. We calculate the classical capacity of a particular correlated noisy channel and show that in order to achieve Holevo limit, we must use $d$ particles with $d$ degrees of freedom. Our results show that entanglement is a useful means to enhance the mutual information. We choose a special non-maximally entangled state and show that in the quasi-classical depolarizing and quantum depolarizing channels, maximum classical capacity in the higher memory channels is given by the maximally entangled state. Hence, our results show that for high error channels in every degree of memory, maximally entangled states have better mutual information.Comment: 15 pages, 5 figures, PHYSICAL REVIEW A 75, 042301 (2007

The potential of black ant (Dolichoderus sp.) as a biological control agents of the coconut leaf beetle (Brontispa longissima)

The study of coconut leaf beetle infestation, Brontispa longissima on palms and the effectiveness of biological agents as a method of control have been carried out in the laboratory. The study involves the effectiveness of potential black ants as biological agents in controlling beetle populations. The results of laboratory studies on the ability of black ant predation on the B. longissima found that the percentage of mean beetle are eaten by the group that has the number 100 black ants were higher and significantly different (P <0.05) as compared to group numbers 5, 20, 50 and 75 black ants. In addition, black ants also tend to attack and devour the B. longissima larvae and pupa stage compared to adult’s beetle via laboratory studies. It can be concluded that the B. longissima beetle has a great potential for causing considerable damage to the coconut tree which could affect coconut palm industry in Malaysia. However, the usage of biological agents as a control method had shown promising results in order to control the beetle infestation in coconut palm areas

GO-Fe3O4 nanocomposite from coconut shell: synthesis and characterization

Synthesis and characterization of graphene oxide nanocomposite from coconut shell GO-Fe3O4 has been done. Graphene oxide can be prepared using Hummer's method and Subsequently, the synthesis of GO-Fe3O4 nanocomposite was carried out by ultrasound assisted co-precipitation of iron (II) and (III) chlorides in the presence of GO. The formation of GO and graphene-Fe3O4 nanocomposite was confirmed by X-ray diffraction (XRD), Fourier transform-infrared (FTIR), SEM and Raman spectroscopy. The characteristics of GO-Fe3O4 as a result of synthesis from coconut shell analyzed using XRD showed that GO characteristics peak in accordance with the characteristics of GO-Fe3O4 in (JCPDS No. 88-0315). Analysis using FTIR was seen in 3421 cm -1 (O-H stretching), 1631 cm -1 (C = C aromatic), and 565 cm -1 (Fe-O). Analysis using SEM seen in the presence of Fe, O and C in the EDX analysis confirmed the formation of GO-Fe3O4 nanocomposite. Analysis using Raman spectroscopy showed that peaks of Fe3O4 were at wavelengths of 396 cm -1 because sp 3 carbon was bound to Fe3O4 so that the peak band D was not present in GO-Fe3O4 spectroscopy

Self-Assembly of Supramolecular Triblock Copolymer Complexes

Four different poly(tert-butoxystyrene)-b-polystyrene-b-poly(4-vinylpyridine) (PtBOS-b-PS-b-P4VP) linear triblock copolymers, with the P4VP weight fraction varying from 0.08 to 0.39, were synthesized via sequential anionic polymerization. The values of the unknown interaction parameters between styrene and tert-butoxystyrene and between tert-butoxystyrene and 4-vinylpyridine were determined from random copolymer blend miscibility studies and found to satisfy 0.031<χS,tBOS<0.034 and 0.39<χ4VP,tBOS<0.43, the latter being slightly larger than the known 0.30<χS,4VP≤0.35 value range. All triblock copolymers synthesized adopted a P4VP/PS core/shell cylindrical self-assembled morphology. From these four triblock copolymers supramolecular complexes were prepared by hydrogen bonding a stoichiometric amount of pentadecylphenol (PDP) to the P4VP blocks. Three of these complexes formed a triple lamellar ordered state with additional short length scale ordering inside the P4VP(PDP) layers. The self-assembled state of the supramolecular complex based on the triblock copolymer with the largest fraction of P4VP consisted of alternating layers of PtBOS and P4VP(PDP) layers with PS cylinders inside the latter layers. The difference in morphology between the triblock copolymers and the supramolecular complexes is due to two effects: (i) a change in effective composition and, (ii) a reduction in interfacial tension between the PS and P4VP containing domains. The small angle X-ray scattering patterns of the supramolecules systems are very temperature sensitive. A striking feature is the disappearance of the first order scattering peak of the triple lamellar state in certain temperature intervals, while the higher order peaks (including the third order) remain. This is argued to be due to the thermal sensitivity of the hydrogen bonding and thus directly related to the very nature of these systems.
