This study aimed to use multigamma irradiation techniques (nuclear) to improve indigenous purple corn to produce better generation types that can withstand drought, harsh climates, pests and diseases, and high yields. Observation, sampling, irradiation, careful selection, purification, and interpretation...

Lake Toba is the largest volcanic lake in Southeast Asia that has a multi-sectoral role, both for the benefit of local communities and for national and even international interests. Lake Toba as a tourist destination where in 2020 the Toba Regency Central Statistics Agency recorded the number of passenger...

This study investigates the influence of Cobalt in magnetorheological elastomer (Co-MRE) on which the magnetic effect could be applied in soft optical electronics such as wearable and flexible sensors. Polydimethylsiloxane (PDMS) was used as a medium, and Co was used as a filler to construct isotropic...

WMO states that temperature is an important parameter in life and defines temperature as a physical quantity that characterizes the average random motion of molecules in a physical body. The accuracy of temperature measurement on a thermometer is influenced by the selection of the right and accurate...

Silat village is a village upstream of the Kapuas River, which is the longest river in Indonesia. One of the tributaries of the Kapuas River is the Silat River. The history of population distribution on the island of Kalimantan, especially West Kalimantan is through water transportation, this condition...

Practical activities can help teachers deliver material because students are directly involved and observing. In addition, practical activities also help students understand concepts. This research aims to make teaching aids to understand the concept of light propagation on fibre optic cables in schools....

This research was conducted in the Seropan underground river in the Gunung Sewu karst, Gunung Kidul Regency. This study aimed to identify some of the flood hydrograph properties of the Seropan underground river to characterize the karst aquifer. A water level data logger is installed to detect underground...

The increase in energy demand and reduced energy reserve, other alternative energy sources that are more environmentally friendly are needed, one of which is solar cells. Among several types of solar cells, Dye Sensitized Solar Cell is a type of solar cell that can produce electricity more efficiently....

DSSC is a permanent alternative energy device in the form of environmentally friendly photoelectrochemical as a renewable energy source. So, the Efficiency of DSSC is still varied and relatively low. Therefore, in this study, a study was conducted on the effect of the composition of rGO/TiO2 as a photoanode...

That publicity to extremely Low Frequency (ELF) magnetic fields can save and suppress the increase and proliferation of pathogenic microorganisms, which have a vital role in the process of meal spoilage. This has a look at pursuits to have a look at the “Resilience of broiler meat thru exposure to extremely...

Although art scholars are primarily concerned with instruction, one of literature’s fundamental purposes, it may also be appropriate for non-art scholars, such as geological scientists. Geology lessons can be taught using literature, such as cave exploration. An alternate strategy for bringing people...

Applying a favorite semi-efficient method, the influences of a typical silane coupling agent, named aminopropyltriethoxy Silane (APTES), on morphology, hardness, and tensile strength behaviors of the natural rubber/silica composite were examined. As a natural-based rubber, the natural rubber (NR) was...

In the application of a semi-efficient method for the rubber compounding and vulcanization, the study on the effects of oleamide addition, as a rubber additive, on the strength and reinforcement behaviors of styrene butadiene rubber (SBR)-silica compound was carried out. The oleamide was synthesized...

Photosupercapacitor (PSC) is integrated harvesting (DSSC) and storing energy (supercapacitor) simultaneously. The increase in DSSC performance is studied through an effect of TiO2 film immersion duration on the N719 dye, which has not been investigated so far. Furthermore, the effect of stacking configuration...

Supercapacitors are gaining much attention as electrochemical energy storage for their fast charging rates, high power density, good cycle performance, quicker charge-discharge, longer device life, and abundant materials. According to the storage mechanism, supercapacitors are divided into 3 types; EDLC...
