Abstract
In the roadmap of Indonesian Bureaucratic Reformation Agendas, one of the goals to be realized in 2025 is the professionalism of the Public Service Apparatus (PSA). The millennium generation of PSA (Gen Y) is expected to play bigger and better role in the realization of the goal than its parents, the baby boomer generation. Accordingly, the first is challenged to boost their capacities and qualities as fast as possible in spite of the limited budget available for their development. This will be possible if the Gen Y is capable of doing Self-Directed Learning (SDL). In regards to that, this paper discusses the Gen Y perspective of their ability in carrying out of SDL. It aims to identify both challenges and resolution to be faced by both the Government Institutions responsible for training and educating PSA in Indonesia and their parent organization. The discussion is based on a survey conducted on the millennial generation of Indonesian Public Service working in several central and local governments.

Abstract
One form of development activities carried out by humans is the exploitation of natural materials energy. Often the activity of exploiting natural material energy is only oriented to human interests, but ignores aspects of sovereignty (autonomy) of nature and the future of members of the local community of exploitation place. This paper shows field observations and literature reviews on the practice of energy exploitation of natural materials in Eastern Indonesia, which lacks attention to the dimensions of the balance of nature and the interests of local communities. Eastern Indonesia has not prospered because it is still struggling to obtain their sovereignty in the exploitation of natural materials in their own land. Often social conflicts arise due to the exploitation of material energy carried out. The research method uses interpretative analysis and philosophical reflection to get meaning. Research found a theoretical model that is useful for overcoming the problem of exploitation that occurs. Those humans must transform themselves into ecological human beings so that they can bring practical benefits to the good of nature and East Indonesia local people towards the vision of sustainable development.

Abstract
ABSTRACT Purple sweet potato (Ipomoea batatas L) contains many acylated anthocyanins which are beneficial for human health. Purple sweet potato roots are easily damaged due to the high water and nutrient content. To extend the shelf life of purple sweet potatoes can be done by a drying process. The drying process can affect the color and amount of anthocyanin. The purpose of this study was to analyze the effect of blanching on color and the amount of anthocyanin of dried slice purple sweet potato. The blanching method studied was steam blanching with a temperature of 70oC-80 oC and blanch with boiling water 90 oC – 98 oC for 2 minutes. To measure the amount of anthocyanin by the pH difference method and measure color using the chromameter tool. The results showed that the steam blanching technique produced a higher color and amount of anthocyanin of dried chips purple sweet potato compared to blanching boiling water. This is because Anthocyanin dissolves in water. The conclusion is to get the color and the relatively high amount of anthocyanin in dried pieces of purple sweet potato can be done by steam blanching.

This study uses a qualitative approach with ethnographic methods. The research subjects consisted of 6 (six) young jockeys aged 5-10 years and 7 (seven) horse owners. Data is collected through observation, interviews, and documentation. Findings: Horse racing is a traditional game of the Dompu-Indonesian community that serves as a means of transforming gross motor skills in early childhood aged 5-10 years. The results of this study indicate that the transformation of gross motor skills for children through traditional horse racing games takes place through four stages, namely watching, motivating, trying, and practicing. The transformation of gross motor skills is carried out with the guidance of friends and adults. The place for transformation of gross motor skills starts in the river when bathing horses, then exercises regularly in the fields, on the seafront, and in the arena of the official racetrack. Previous research shows that horse riding can be a way to help develop physical motor skills of children, especially children with autism and down syndrome. Horses can be an intervention and therapy tool for children with special needs. While the traditional tradition of horse racing in Dompu can be a place of conservation of local culture, namely preserving culture to continue to live as a cultural heritage and regional identity. This study informs that the development of gross motor skills of children can be carried out since 5 years old children through traditional horse racing games. Riding a horse assisted by adults can help cure autistic children and down syndrome. This research can also be a reference for early childhood education practitioners to create a special school for children who have a hobby of riding horses.

Abstract
The urban air environment that has been polluted by vehicle and industrial exhaust emissions pollutants causes dry and irritated skin. Cinnamon essential oil containing cinnamaldehyde (60.72%), eugenol (17.62%) and coumarin (13.39%) functions as an antibacterial and can treat skin due to polluted air environment. Cinnamon essential oil can be used as a cream and soap ingredient. Soap and cream products can be used for skin care. Cinnamon trees are widely planted in the Subang area of West Java. This study aims to determine community empowerment in the Subang area in developing the processing of essential oils. The research was conducted by surveying the training sites of the Subang community in developing plantations of cinnamon trees and processing them by steam distillation, so that essential oils were obtained. Samples were taken purposively as many as 30 people. The results of the study show that a. through steam distillation, cinnamon essential oil is obtained, b. cinnamon tree waste such as leaves can be processed distillation into essential oils, c. Local people can practice processing essential oils as a result of training, and d. The community can develop the business of processing cinnamon essential oil independently, so that it can be used to add value to family income.
