Isopulegol is a highly volatile compound. One method for preserving highly volatile compounds is electrospinning. One of the factors that influence electrospinning stability is matrix composition. In this study, isopulegol-PVA nanofiber with a variety of matrix compositions is made by electrospinning techniques to determine the effect of matrix composition on the characteristics of nanofiber and the comparison of isopulegol peak area on the best nanofiber. Making solutions according to predetermined composition. The solution was electrospinning by setting a 10 mL syringe which has a metal needle with 0.6 mm inner diameter. Electrospinning parameters are adjusted, such as the voltage is 18 kV and the distance of the needle tip to the collector is 10 cm. The results of nanofiber were analyzed using FTIR-ATR and SEM. Based on the research, the composition of PVA-maltodextrin-isopulegol (1:1) nanofiber is better than PVA-maltodextrin-isopulegol (1:2) nanofiber. The composition of PVA- β -cyclodextrin-isopulegol (1:2) nanofiber produces better fiber than PVA- β-cyclodextrin-isopulegol(1:1) nanofiber. The diameter of the resulting PVA nanofiber is 92,891 nm; PVA-maltodextrin-isopulegol (1:1) nanofiber is 94.02 nm; and the PVA- β -cyclodextrin-isopulegol (1:2) nanofiber is 100,242 nm. The results of the comparison of isopulegol peak area from the best isopulegol nanofiber (PVA- β -cyclodextrin-isopulegol (1:2)) are unstable

Banana tree fiber is a natural fiber that has been widely applied to various needs, for example to a mixture of fabrication composite material, carbon film, and so on. To get a strong composite material, special treatment is required by add another material like nanofiller silica carboxyl (SiO2-COOH), then combined with various types of resin, so that the fiber-based composite material has stronger characteristics than fiber carbon, fiberglass, and another high strength material. The purpose of this study was to determine the effect of resin type and nanofiller concentration on the mechanical properties of composites. In this research, a composite resin with banana tree fiber was reinforced with the addition of nanofillers with the variations used namely the type of resin and the concentration of the nanofiller. The best variation in nanofiller concentration is the variation with a concentration of 0.05% w/v in the type of vinyl ester resin. Scanning Electron Microscopy (SEM) shows that nanofiller morphology has been evenly distributed inside the resin matrix. While the tensile strength test using the Ultimate Tensile Machine (UTM) tensile strength test tool Chun Yen 10 kN obtained a tensile strength value of 89.57 MPa and an elongation value of about 1.20%.

Indonesia has the potential for natural fiber wealth which is very abundant and varied therefore it is a very interesting opportunity in the development of polymer composites using natural fiber from a banana tree. To get a composite material that has strong mechanical properties, that is by adding other materials such as nanofiller (Al2O3, SiO2, and TiO2) combined with vinyl ester resin and banana tree fiber using the hand lay-up method to produce a composite that has stronger mechanical properties than fiberglass. In this research vinyl ester composite synthesis reinforced with banana tree fiber with the addition of nanofiller which aims to determine how the effect of nanofiller type and nanofiller concentration on the mechanical properties of composite and how the bonding strength of composites through SEM analysis. The results showed that for the Al2O3 nanofiller, the highest tensile strength was with a fraction of 5% with a value of 74,81 MPa with an elongation of 1,07%, for SiO2 nanofiller the highest tensile strength was with a fraction of 0,05% with a value of 89,57 MPawith an elongation of 1,20%, and for TiO2 nanofiller the highest tensile strength was with a fraction 0f 1% with a value of 75,33 MPawith an elongation of 1,05%. The results of SEM analysis show a fairly good matrix bond.

As the sea possesses rich variations of resources, it also imposes threats to the security and defense interests of a nation. Oil and gas exploration is one of the most important economic activities in the sea. In Indonesia, hundreds of offshore oil and gas platforms comprise thirty percent of the total oil and gas production. This signifies the importance of their establishment to the economy. However, their potentials do not stop there. As Indonesia is comprised of a very vast water area, the surveillance system still needs improvement. The article proposes to combine these interests into manifesting a simple surveillance system in offshore oil and gas platforms to improve defense and security systems, both for maritime routes in general and also the installations. The proposal prioritizes installations that are no longer operating, shifting their functions for other beneficial means. This is supported by the current law and regulations of the sea, both at the international and national levels. The international law of the sea implies that surveillance and data collection is allowed within the jurisdictional and territorial waters, whereas national levels allow functional shifting and defense system improvement in installations as long as it is coordinated with relevant ministries.

Water as the main necessity of life should be fulfilled in quantity, quality, affordability, and continuously. However, there are many people still do not get proper clean water, especially in rural and suburban areas. The PAMSIMAS program is one of the mainstay programs of the Government that provides clean water and sanitation for rural and suburban communities through a community-based approach. The strength of developing drinking water and rural sanitation is very dependent on the social capital of community and local government. The PAMSIMAS program provides great support to encourage the realization of the sustainability of the water supply and sanitation system so that the community and village government can be focus in the PAMSIMAS approach in their village policies and to be able to maintain the sustainability of the PAMSIMAS program management.

This article discusses culture and social issues in the community related to herbal medicine used for health communication and community empowerment in Bandar Lampung. Additionally, herbal medicine plays a significant role in empowering families from the dependence of conventional medicine and developing traditional medicine. A good health level of community is an asset of Indonesia's human development that is independent, healthy, and strong. Using the qualitative research approach, the data source consisted of interviews, deep observations, and documentation. The results are herbal medicine 1) empowers the community for better family finance, 2) empowers people to get a job, 3) creates a new paradigm, making herbal medicine the first treatment choice when one is sick, instead of conventional medicine (medics). This study's findings describe the culture of the Indonesian people who are accustomed to drinking herbal medicine. Therefore, traditional herbal medicine needs to be empowered as a unique Indonesian culture, as it is possible to combine herbal and conventional medicines. This research contributes to policymakers to make herbal treatment models holistically, to support Program Indonesia Sehat (Indonesian General Health Program).

This article is a theoretical review for describing multimodal literacy in elementary school learning. The exposure in this article is based on the application of multimodal literation. This paper relates to the pedagogic aspect of the implementation of multimodal literacy learning in the view of constructivism. Learning aims to prepare students for the era of the 4.0 Industrial Revolution. The idea of Literation has now changed because at this time it relates to digital content. Thus, multimodal literacy needs to be examined to explain the role of multimodal literacy in elementary school learning
