Abstract

This study investigated the effect of calcination temperature on the phase composition and crystal size of zinc oxide powders synthesised by the sol-gel method. Zn powder, HCl and NaOH were used as precursors in a multi-step process involving dissolution, titration, gel formation, leaching, drying and calcination at temperatures ranging from 300°C to 700°C for 2 hours. Rietveld analysis of X-ray diffraction (XRD) data using MAUD and Rietica software determined phase composition and crystal size. Initial analysis identified a single simonkolleite phase (Zn5(OH)8Cl2) prior to calcination, which disappeared at 500°C. Wurtzite (ZnO) appeared at 300°C, accompanied by secondary phases (NaCl and ZnCl2). The wurtzite content increased to 81.42 wt% at 700°C. Calcination temperature also influenced crystal size, which ranged from 27.34 nm to 110.61 nm for wurtzite at different temperatures. The results highlight the dynamic changes in phase composition and crystal size with different calcination temperatures, providing valuable insights into tailoring zinc oxide properties for various applications.

Abstract

The flight information region adjustment agreement between Indonesia and Singapore, as the Realignment Flight Information Region Agreement, has been ratified by Presidential Regulation Number 109 of 2022 concerning Ratification of the Agreement between the Government of the Republic of Indonesia and the Government of the Republic of Singapore concerning the Adjustment of Boundaries between the Jakarta Flight Information Region and the Singapore Flight Information Region on September 5, 2022. The problem to be discussed is How are the regulations for ratification of boundary adjustments between Jakarta flight information regional and Singapore flight information regional based on laws and regulations in Indonesia? and What are the implications of ratifying the adjustment of the boundaries between Jakarta's regional flight information and Singapore's regional flight information with presidential regulation number 109 of 2022?. With the normative legal research method (normative legal research). The regulation of ratifying the adjustment of the boundaries between Jakarta's regional flight information and Singapore's regional flight information is regulated by Law Number 1 of 2009 concerning Aviation and its implementing regulations. This law also refers to the regulations of the International Civil Aviation Organization (ICAO), which is a global reference in the management of airspace and FIR as well as the Indonesia-Singapore Flight Information Region (FIR) Adjustment Agreement 2022. The implications of ratifying the adjustment of the boundaries between Jakarta's regional flight information and Singapore's regional flight information with presidential regulation number 109 of 2022 occur in the Implications in the political field, Implications in the Economic field and Implications in the field of national defense and security. The regulation of ratifying the adjustment of the boundaries between Jakarta's regional flight information and Singapore's regional flight information Indonesia must strengthen and maintain the FIR areas on maps A and B so that they are not managed again by Singapore. The implication of ratifying the adjustment of the boundaries between Jakarta's regional flight information and Singapore's regional flight information is that Indonesia must think about immediately regulating a Single Air Traffic Provider where all Indonesian airspace is regulated in one FIR (Flight Information Region). Keywords: presidential regulation, FIR, boundary adjustment

Abstract

The ZnO-TiO2 films were co-sensitized with single, double, and triple natural dyes, leading to distinct effects on the optical properties. ZnO (wurtzite) and TiO2 (anatase) were prepared from commercial powders and the XRD results revealed that the crystallite size is 158 and 443 nm, respectively. The UV absorbance of ZnO powder shows significant peaks at wavelengths of 255 and 345 nm, with a band gap energy of 3.07 eV. Meanwhile, TiO2 powder exhibits a maximum peak at 325 nm and possesses a band gap energy of 3.16 eV. The extraction of natural dyes (Moringa oleifera, Biancaea sappan, Matricaria chamomilla, Rosa, and Chrysanthemum) was carried out using a cost-effective and simple method involving immersion in ethanol for 2 × 24 h followed by filtration. FTIR test results show the presence of O–H, C–H, C=C, and C–O functional groups. The results of coating the ZnO-TiO2 film with natural dyes show that the UV spectrum peaks are higher than the visible light wavelength. Co-sensitization of double natural dyes demonstrated different effects on the ZnO-TiO2 film, i.e., achieved panchromatic absorption mainly in the UV wavelength spectrum.

Abstract

Zn-doped magnesium titanate powders with different Zn compositions, x = 0 to 1, were synthesized using the dissolved metals mixing method. The roles of calcination temperature and dopant Zn composition on powder morphology, phase composition, crystallite size, crystalline cell volume, and local environment were investigated through scanning electron microscope (SEM) observation, Rietveld analysis of powder X-ray diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy and X-ray absorption spectroscopy (XAS) for Ti K-edge X-ray absorption near edge structures (XANES). We found that the geikielite solid solutions were formed during the pre-calcination at 400 °C for 1 h. Results show spherical particles (~1 µm) with minimal size variation across calcination temperatures (600–800 °C) and Zn compositions, though some agglomeration occurs. After calcination at 600 °C for 4 h, the crystalline cell volume of geikielite was proportional to the Zn composition, implying the formation of the solid solution in the range of Zn composition up to the level close to x = 1. This successful synthesis of the Zn-doped magnesium titanate nanocrystals at temperatures much lower than those required by the solid-state reaction method was thereby well demonstrated.

Abstract

Extraction and study of the optical properties of natural dyes from several plant parts such as leaves, flowers, tubers, and fruits have been carried out using a simple maceration method and UV-Vis absorption characterization. The samples were divided into several groups in this study, namely the flower group (Tagetes sp., Paeonia sp., Centaure sp., Chrysanthemum sp., Carthamus tinctorius, Gomphrena globosa, Myosotis sylvatica, Lavandula sp., Clitoria ternatea, Matricaria chamomilla, Hibiscus sabdariffa, and Rosa sp.); the leaf group (Mangifera indica, Moringa oleifera, Graptophyllum pictum, Spinacia oleracea, Citrus hystrix, and Terminalia sp.); and the tuber and fruit group (Solanum lycopersicum, Cucurbita moschata, Garcinia mangostana, Curcuma longa, Beta vulgaris, and Caessapina sp.).  The extract of natural dyes was successfully produced using a low-cost and simple extraction approach via dehydration, immersion for 2×24 hours in ethanol, and followed by filtration. The optical properties of the dyes in UV and visible light range were observed using a UV-Vis spectrophotometer in the wavelength of 400-700 nm. The absorption behaviour showed dominant peaks at different wavelengths for each group. Potentially, to do a combination of dyes (co-sensitization: using more than a dye with different absorption spectra to achieve a panchromatic response) to widen the wavelength absorption for dye-sensitized solar cell (DSSC) applications.

Abstract

A green physical setting would need green behavior and culture to sustain and function properly. Education is a key component to form a sustainable mindset and lifestyle for society, especially youth. As a university with a vision to be a resilient and healthy campus, Universitas Gadjah Mada has actively involved in providing education for sustainable development. The activities have commenced since 2016 through Integrated Smart and Green Building research group and involve participants from both internal and external audiences. Internal target audiences were primarily freshman UGM students and later extended to include primary and high school students. External audiences were the government and stakeholders from the commercial sector. The program was designed to increase awareness on sustainable development and encourage everyone to take part to achieve its goals. Students were educated on the importance of sustainable lifestyle and expected to practice green behavior in their daily life. For stakeholders, a focus group discussion was organized to start a conversation for the formulation of green building regulation. There were observable immediate changes in cognitive and behavorial domain toward sustainable lifestyle. Sustainable development is a long term vision and it needs participation from everyone. Higher education as a center of knowledge should actively provide society with education to achieve sustainable development.

Abstract

Water management is one of the most challenging aspects of campus management. With a large number on campus population and limited water resources, water management is essential for achieving a resilient and healthy campus. In this paper, we explain two targets in UGM water management: water efficiency and water conservation. Both objectives are significantly related; however, each goal has a different approach to the method for the design approach and strategies in the implementations. Water efficiency is included in building new buildings and retrofitting the existing ones. Meanwhile, water conservation is implemented to calculate potential alternative water resources in UGM, including water treatment, to produce freshwater as an additional water supply. We also explain how water management is implemented in UGM from the highest Directorate to the lowest units. Through our method and best practices in UGM, we hope our paper could be a reference for other universities who want to implement a water management program.
