The sol-gel method offers several advantages over other techniques for synthesizing nanocomposites, including simplicity, cost-effectiveness, and low processing temperatures. In this study, a silica-supported CaO nanocomposite was synthesized using eggshells as the calcium source and rice husk ash as the silica support via the sol-gel method. The green silica-supported CaO nanocomposite was characterized using various techniques, including BET surface area and porosity analysis, FTIR for functional groups identification, XRD for crystallinity and crystallite size determination, SEM and TEM for surface morphology examination, as well as TGA for thermal stability assessment. The XRD and the FTIR analysis clearly demonstrated the successful synthesis of the silica-supported CaO nanocomposite. The silica-supported CaO composite had a crystalline structure combination of 55.45 % silica and 20.46 % CaO, as well as exhibited the stretching vibrations of Si-O-Si, Ca-O, Si-O-Ca, and Si-O functional groups and a bending vibration of Si-O functional group. The SEM and the TEM images revealed that the composite particles were irregularly shaped and evenly distributed compared to green-silica (G-silica) and green-CaO (G-CaO). The particle size of the composite was distributed in the range of 0.1-100 nm, with a more uniform distribution compared to G-silica (dominant in the range of 80.1-100 nm) and G-CaO (dominant in the range of 0.1-20 nm). TGA results showed that the thermal stability of the silica-supported CaO composite was enhanced by silica support compared to G-CaO. These findings demonstrate that CaO derived from eggshells and silica from rice husk ash are promising materials for the fabrication of multifunctional silica-supported CaO nanocomposite.

Technological progress demands the development of materials that have special characteristics such as high strength, stiffness, light weight, and good thermal conductivity at a low price. The development of hybrid metal matrix composites is the most important field in advanced materials science engineering. This research determines about aluminum matrix composites (AMC) reinforced with alumina (Al2O3), Silicon carbide whisker (SiCw), and magnesium (Mg) addition. The matrix is made of 90 % pure aluminum powder, and commercially available reinforcing materials include Al2O3, SiCw, and Mg. Objectives include variation of reinforcement fraction and matrix, sintering holding temperature and time. The selection of the sample making process using powder technology followed by the sintering process at different temperatures namely 350, 450 and 550 °C with variations in holding time of 1, 2 and 3 hours. The purpose of this study was to determine the effect of variations in the fraction of reinforcement and sintering treatment on the properties of wear resistance, hardness and thermal conductivity of aluminum matrix composites. The results showed that the composition ratio of reinforcement to aluminum in sintering treatment significantly affected the mechanical properties. The wear resistance of the material shows excellent performance, namely wear resistance of 0.000065 gr/s, hardness of 45.234 VHN and thermal conductivity of 184.855 Watt/m °C, at a reinforcement composition combination of 10 % Al2O3, 10 % SiCw and 20 % Mg and a sintering temperature of 550 °C. This indicates that the Aluminum matrix composite reinforced with Al2O3/(SiCw/Mg) is able to support the friction load due to its low wear rate, good hardness, and good thermal conductivity. This material is very suitable to be used as tribology material, brake element, especially brake drum. [ABSTRACT FROM AUTHOR]

The inheritance system in Balinese customary inheritance law is known as the kapurusa system. This kapurusa system is patrilineal and is inspired by Hinduism. The issuance of the Decree of Pasamuhan Agung MUDP Bali Province in 2010 was an initial milestone in the change in the mindset of granting inheritance rights to girls and boys who married nyentana or married out with their wives. Therefore, it is necessary to research the dynamics of inheritance according to Balinese customary inheritance law and its relationship with Hindu law regarding inheritance. Using empirical-normative legal research methods, the findings in this research are the development of a shift in thinking that only sons have the right to inherit the gunakaya or wealth of their parents, which has begun to be seen from the existence of financial gifts or bequests which were previously not done by many people. Parents to their daughters or sons who are getting married is illegal, but now it is common practice. The connection between Hindu law and Balinese customary inheritance law in the field of inheritance can be seen from adopting the kapurusa or patrilineal system in Hindu law. However, it still allows daughters to be the principal heirs by being confirmed as Santana jeg or elevated to equal status with sons. [ABSTRACT FROM AUTHOR]

Meta-figurative is a physical aesthetic discourse that reaches beyond the physical beauty of ideal bodies (skeletal construction, muscles, and skins). The interpretation approaches used new criticism, according to Culler (2001), that goal to identify what the works repress or illuminate by concealing and portraying society and social attitudes. Meta-figurative encompasses exploration pertaining to the interchangeable position and condition between tensions and pleasures of bodies in the social space. Fifteen Indonesian contemporary artists are: Mangu Putra, Entang Wiharso, Chusin Setiadikara, Agus Suwage, FX Harsono, Ivan Sagito, Heri Dono, Ronald Manulang, Nyoman Masriadi, Nyoman Erawan, Putu Sutawijaya, Laksmi Sitaresmi, Made Djirna, Ugo Untoro, and Bob Sick Yuditha have been conducting creative efforts and questioning about matters of the bodies' position in the public space, conducting current interpretation through personal artistic and aesthetical language. There are five representation tendencies of meta-figurative paintings thematically, artistic images, and visual meanings: marginalized bodies, fictionalized bodies, bodies of expression, autobiographical bodies, and beyond famous portraits. Indonesian contemporary artists have made figurative subjects in their paintings to make statements, selfreflections, and moral voices of their country's socio-political conditions, which are educational values of Indonesian Contemporary Paintings in social meaning. Poverty, corruption, and antidemocracy practices still part of Indonesian daily realities are area protests for contemporary artists. [ABSTRACT FROM AUTHOR]

Drama Gong is a traditional Balinese performance art that enjoyed popularity. However, since the 1990s, the advent of television and the internet has led to a decline in the prominence of Drama Gong. Therefore, there is a pressing need to revitalize and innovate this traditional art form. One such effort by Balinese artists involves the creation of a digital adaptation known as 'Drama Keraton Cilinaya.' This qualitative descriptive research aims to explore the development model of Drama Gong in the digital era. The research data were collected through a comprehensive document analysis, which included the examination of seven episodes of 'Drama Keraton Cilinaya,' as well as direct observations and interviews with the creators. The findings revealed that 'Drama Keraton Cilinaya' has undergone significant internal and external innovations. Internally, the artists emphasized the importance of having an open mindset to embrace global changes, packaged stories for enhanced appeal and comprehension, incorporated contemporary dialogue, employed multiple languages, engaged younger talents, enhanced makeup and costume artistry, introduced digital music, and improved stage layouts. External innovations involve collaborations with artists beyond the Drama Gong tradition, utilizing digital technology in production, and distributing the performances through TV media and YouTube channels to broaden their audience reach. It is anticipated that the findings of this research will serve as a valuable digital packaging model, not only for Drama Gong but also for the development of other traditional Balinese performing arts, ensuring their sustainability in the digital era.
