Every year, more than 50 million metric tons of apples are produced, and apple pomace is frequently discarded as waste in the food industry. Apple pomace, a byproduct of apple juice and cider production, is used as a sustainable raw material to make valuable products such as nutraceuticals and pectin. Apple pomace contains a substantial amount of antioxidant compounds, which have been related to several health advantages. Therefore, valuable components extracted from this byproduct may be used in the food and pharmaceutical industries. The common and new technologies to obtain valuable products from apple pomace which has come from production of apple juice or cider. Especially, emphasis of new and green technique is very important and will contribute the literature. Therefore, this review discussed apple processing, pectin as a bioactive compound, the extraction methods, current applications of apple pomace byproducts, and future studies on its potential uses in food.

Indonesian government is accelerating the development of national housing through its stateowned company, in which all planning designs have been already established including urban design and urban revitalization. But unfortunately the detailed engineering of installation building, especially roof insulation building has not gotten much attention yet. Main contractor was paid for the project but the insulation should be an extra work to be paid due to its status as variant order. So, any kind of insulation types are pleased to be proposed. This paper proposed Material and Cost-Based methods that was studied by comparing three proposed materials from physics and economic point of view with its theory and simulation data whereas computer simulation also conducted. Evidently, insulation has an important role to be installed due to gaining solar heat reduction from solar exposure through the rooftop based on indoor thermal condition and energy of cooling utilities. Besides, those methods presented the simplified decision for company to select a beneficial material to be installed.

Southeast Asia is expecting rapid growth in energy and vehicle demand. Variable renewable energy such as solar and wind have high potential in the region. ASEAN aims to increase the renewable energy share in power capacity to 35% 2025. The increase in renewable energy share can drive a shift in the current energy management system. The adoption of electric vehicles can bridge the link between the energy and vehicle sectors towards a green transformation. Electric vehicles that are powered by electricity from renewable sources creates demand by consuming energy from the grid, but it can also serve as battery storage that can discharge energy back to the grid if needed. It is known that the intermittent nature and high penetration of variable renewable energy can lead to power instability. However, microgrids can be designed and incorporated with electric vehicles and variable renewable energy deployments to enhance the reliability and stability of the power system. The engagement with key stakeholders related to the deployment of the platform for the use of these three technologies is crucial to gain better insight on the market status, including the current and future price and penetration trends, and deployment opportunities and barriers. A focus group discussion involving related stakeholders on the aspects of policies and targets, technology readiness, and implementation strategies, was thus conducted. The results showed that there have been concrete policies on the renewable energy installation targets among the countries. Electric vehicles penetration is also an existing priority with different countries having varying targets for the electric vehicle fleets and charging stations. However, for microgrids, it was found that there is less information on their deployment and application. As such, more detailed technical and economic assessment following its potential connection to current grid with other features including variable renewable energy and electric vehicles, as well as the available smart features in optimising power scheduling, should be carried out.

This study aims to examine differences in the management of innovation in the MABATUTER education program (Management of Integrated Reading and Writing Applications) for studentsmanagement conditions carried out by schools conventionally and digitally.The research method used was a qualitative before-after experiment, namelycompare the assessment of parents of students related to program managementMA-BATUTER education carried out conventionally with the after conditionimplementing digital applications developed independently byby PAUD TAAMASA Sumbawa. The research data were obtained from 10 sampling peopleparents of students using a score-based assessment instrument on the aspectread, write, and retell. To determine the effectiveness of different testsusing non-parametric statistics through Wilcoxon test, gain score test. Resultt-test research and gain score of MA-BATUTER education program with applicationdigital is proven to be effective in improving students' ability to understand the content of the storyand can retell the information received in order to trainintelligence sensors of children from an early age.

Factors affecting the safety and health of the work environmentprocessing of rice and maize at PT XYZ Sumbawa Branch, West Nusa Tenggara accordinglywith Permennaker No.5 of 2018 are noise, vibration, lighting, temperature andhumidity, wind speed and water. Occupational health and safety is aresponsibility of all workers. A very healthy, nurturing and safe working climatesupport the increase in labor productivity as a human resource. Aimfrom this research is how the K3 program on the activities of PT. XYZ BranchSumbawa, how to work climate factors such as noise, vibration, temperature andhumidity, wind speed, water and lighting referred to in PermenakerNo.5 of 2018 in the work activities of employees and workers at PT. XYZ SumbawaWest Nusa Tenggara, and whether the K3 working climate is in accordance with Permenaker No.5 of 2018has been implemented by PT. XYZ Sumbawa Branch. The research method usedin this research is experimental quantitative. The object of this research is workersPT. XYZ Sumbawa, West Nusa Tenggara. This research data comes from the placeprocessing of corn and grain at PT. XYZ Sumbawa, West Nusa Tenggara. DataThis research is the result data from the vibration test using a vibration meter, testnoise using a sound level tool, using a temperature and humidity metergun and humadity thermometer tool, lighting test using anemometer, testwater using a PH meter and TDS, wind speed test using an air flow toolanemometer. The research data were analyzed descriptively and quantitatively based on the dataquantitative. The results of this study indicate the factors that influence the work climateare noise, vibration, temperature and humidity, wind speed, water and lightingas referred to in Permenaker No.5 of 2018 has no effect onwork activities of employees and workers at PT. XYZ Sumbawa, West Nusa Tenggara.Meanwhile, the work climate of K3 according to Permenaker No.5 of 2018 is not allimplemented by PT. XYZ Sumbawa Branch because there are several working climatesdoes not comply with government standards namely noise (89.5-99.6 dBA) vibration (5.2-5.5 m / s2), and temperature (27oc) and humidity (50-62%) workspace while appropriatewith Permenaker No. 5 of 2018 are lighting, wind speed, and water.

Rechargeable battery plays an important role to support the implementation of clean and renewable energy. In this aspect, post Li-ion battery, such as Zn-ion battery is receiving great attention due to its low cost and enviromentally friendly. Therefore, studies of electrode materials for Zn-ion battery are of paramount importance. In this contribution, we present theoretical investigation to explore the potential use of tunnel-type manganese dioxide for zinc storage material. Our calculation suggests the stability of the material for Zn-ion battery application.
