Authors: Wijaksono S
Published: April 2024

One of the goals of Sustainable Development goals is sustainable cities and communities. Making cities sustainable means creating career and business opportunities, safe and affordable housing, and building resilient communities and economies. One of the goals of sustainable cities and communities (SDGs 11) is by 2030, ensure access for all to adequate, safe and affordable housing and basic services and upgrade slums. Because the level of housing needs in Jakarta is quite high with limited land available, housing prices soar, this is inversely proportional to the high level of poverty in Jakarta so that many people make illegal and slum settlements to overcome the lack of funds they have. One way to achieve this target is to apply bioclimatic architecture to realize sustainable buildings with affordable operational costs so that the housing built becomes affordable. One way to save energy is to use natural ventilation. This paper presents a study of the application of bioclimatic architecture that can provide good air circulation created using natural ventilation. Natural ventilation is the process of exchanging air inside the building through the help of open building elements. This research is motivated by the current development of cheap apartment architecture in Indonesia which does not support good natural ventilation, people are starting to build something that benefits the market and ignores the importance of good air circulation. Therefore, the promotion and application of natural ventilation as part of low-cost energy consumption and avoiding the sick building syndrome with good air circulation, especially after the corona virus pandemic, is an important issue. The research method used is descriptive quantitative method, in the form of research with a case study and simulation approach. The result achieved is that the building can optimize natural ventilation evenly through orientation, building shape, opening design, etc.

Published: April 2024

Currently, clean water and environmental issues are becoming a major concern because the source of these issues mostly comes from buildings, one of which is offices. Most buildings apply the energy saving concept, and there are still few that apply the water conservation concept, especially in Indonesia. The lack of references for office buildings that implement water conservation makes it difficult for Indonesian architects to implement this concept. Therefore, this study aims to compare buildings that apply water conservation by looking for data related to similar projects that are used as a reference in a project in Indonesia. In this study, a comparative study of projects in Indonesia was carried out with several projects abroad that implemented the water conservation concept. The projects were examined based on six aspects of applying the concept of water conservation, as well as the layout of reservoir, and comparison of the water tanks amount needs. The results of this study show that projects applying water conservation aspects in Indonesian outbuildings are more diverse compared to buildings in Indonesia, which causes the percentage of water conservation in Indonesian outbuildings to be much more optimal, the location of water storage in all projects is mostly in the basement, and the average amount of water storage is 2.5 to 4 times the water needs.

Authors: Fuadi Aditya , Wardana Ata Aditya
Published: April 2024

The usage of cans as processed food packaging may cause toxicity in the form of metal contamination that is dangerous for the human body. Although canned food products spread in Indonesia have met SNI standards, metal contamination can occur or increase if the handling process is carried out incorrectly. The handling process of canned food that does not follow the standards made by Codex CAC/RCP 60-2005 on temperature exposure, storage time, and physical condition of cans is a factor influencing Pb metal contamination of canned food. Therefore, this study aims to summarize the effect of temperature exposure, length of storage, and physical damage of cans on Pb content in canned food. PRISMA guidelines were used as the method to find suitable sources for this systematic review. Relevant studies that were used are retrieved from several databases such as Science Direct, EBSCOhost, Taylor & Francis, and Wiley Online. The keywords used to identify the relevant studies were “metal contamination”, “heavy metal contamination”, “metal toxicity”, and “canned food”. The initial search in databases yielded 73 articles. After the screening process based on the criteria of the article, only 11 articles were used in the final systematic review. The result showed that storage time is most commonly related to the cause of increased Pb content in canned food compared to temperature exposure and physical condition. Therefore, the market must ensure that the handling process of canned food is carried out following Codex CAC/RCP 60-2005 to reduce the chance of increased Pb content in canned food products.

The optical study illustrates Lawsone dye - Zinc Oxide (Ld-ZnO) composite to utilize in energy conversion application. The FTIR spectra demonstrates the presence of Zn-O, C-O, C=O and hydroxyl groups are evident from near 500, 1633 and around 3250 cm−1 respectively. The UV-Visible spectra reveal maximum absorbance around narrow and broad peak at 368 nm for Lawsone dye (Ld) and Ld-ZnO composite respectively. The lawsone dye has better emission property that causes recombination of charge carriers reduces the performance of Dye Sensitized Solar Cells (DSSCs). The DSSCs based on lawsone dye (Ld) and Ld-ZnO based material exhibits PCE of 0.12% and 0.17% respectively. This optical study suggests natural extraction of lawsone dye from henna leaves with suitable semi-conducting material was promising candidate to improve performance of DSSCs.

Amine modified nano-graphite (NH2-NG) has been produced from nanographite (NG) powder via liquor ammonia (NH3) aqueous solution by microwave, ultrasonic methods. The surface modified NG have been characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and Fourier-transform infrared spectroscopy (FTIR) techniques which clearly demonstrate that synthesis of NH2-NG was successful. The crystalline characteristics of amine modified nanographite powder have been studied through XRD technique. The morphology structure of synthesized surface modified nanoparticles has been determined by SEM analysis. FTIR spectra confirmed the existence of amine groups on the surface of produced nano-graphite powder. NH2-NG pellet was prepared to analyse its dielectric properties as a function of thickness (1, 2, 3, 5 and 7 mm), frequency (range 10−2-105 Hz) and temperature (25, 50, 75 and 100 °C). As a function of frequency, the dielectric loss tangent and permittivity each exhibit a distinct relaxation peak that grows up to a thickness of 5 mm then decreasing. Because nanoparticles are capacitive, the capacitance values of NG and NH2-NG increase with thicknesses up to 5 mm and drop with frequency. The drop in dielectric permittivity of NG and NH2-NG pellets after 5 mm may be caused by an increase in resistivity. Positive temperature coefficient (PTC) of increased conductance is confirmed by the continuous increase in electrical conductivity of NG and NH2-NG with temperature. The degree of temperature has a significant impact on the dielectric loss tangent, dielectric permittivity, and electrical conductivity of NG, and NH2-NG.

This article evaluates the effect of mixing strategy on thermo-electrical resistance of ethylene vinyl acetate (EVA), low-density polyethylene (LDPE) and fumed silica nanoparticles (FSN) based composite encapsulating materials. The nanocomposites were synthesized by solution compounding method with various sequence of ingredients addition. The quantity of ingredients is same for all nanocomposites where the ratio of EVA, LDPE and FSN addition is 10:1:0.11. The structural morphology of the samples prepared by different mixing sequence was studied under Transmission Electron Microscopy (TEM). DC volume resistivity (VR) were evaluated at 25 °C, 50 °C and 75 °C for all the compositions to check the insulation behaviour at extreme service temperature as VR is an assessing parameter for photovoltaic (PV) encapsulating materials. For obvious reason, the magnitude of VR decreases with increasing temperature. Activation energy (Ea
) was estimated from Arrhenius equation and the value evaluated was very much dependent on the ingredients mixing strategy. Good electrical resistance with desired activation energy were obtained for the nanocomposites; prepared with a particular mixing strategy where percolation threshold achieved. Finally, the TEM structure and insulation property relationship has been addressed against the experimental findings.

In the present study, an Alternating Current (AC) response of Vanadium pentoxide (V2O5) doped Polyaniline (PANI) composite was studied. Pure PANI was synthesised by the In-situ polymerisation method. The PANI/Vanadium Pentoxide (PVO) composite was prepared by physical mixing of chemically synthesised PANI with dopant in a vibration mill. The structure and morphology of the samples were characterised by XRD and SEM studies. The Alternating Current response parameters of PANI, V2O5 and PVO composites were studied in the frequency scale of 40Hz to 110MHz at room temperature. The change in the AC conductivity of the composite as compared to PANI and V2O5 was observed and discussed based on the electron-hole exchange mechanism.
