Abstract

Ethanol consumption of the world for a variety of uses has increased very significantly in recent years. Therefore it is necessary to alternate sources of raw materials to manufacture bioethanol and bioethanol production can be increased. Nypa sap is one of potential materials to be processed into bioethanol. This research was conducted the pilot scale fermentation of nypa sap, using Tween 80 and ergosterol as suplement to obtain high concentration of bioethanol as well as prevent osmosis in cells. This work is aimed to study of bioethanol pilot scale production from nypa sap, to determine effect of fermentation time to bioethanol and to obtain maximum conditions on the process. And to determine effect of Tween 80 and ergosterol. Fermentation was conducted in 70 L fermentor having variations of fermentation time such as 24; 36; 48; 60; 72; 84 and 96 hours respectively, variations addition of Tween 80 of 250; 375; and 500 ml respectively, and ergosterol of 25; 37,5; and 50 gr. Stirring speed of 200 rpm and temperature of fermentation at room temperature (25 - 300C). Ethanol concentration was analyzed by using Gas Chromatography. Tween 80 and ergosterol effect on the activity of Saccharomyces cerevisiae in converting nypa sap into bioethanol. The process of fermentation maximum conditions indicated in the addition of Tween 80 [375 ml] and ergosterol [37,5 g] at the time of 84 hours having the initial sugar concentration of 258,641 mg/ml. Concentration bioethanol obtained in this condition at 16,602% (v/v) or 131.040 mg/ml.Keywords: Bioethanol, Ergosterol, Nypa sap, saccharomyces cerevisiae, Tween 80

This study focused on women as victims of toxic relationships, with semi-structured interviews with two female participants who experienced toxic relationships. Aiming to find out the description of the experiences of women victims of toxic relationships, with the uniqueness of each participant, then be analyzed using Interpretative Phenomenological Analysis. The results found five main themes: toxic behavior; motivation to maintain relationships; the impact of a toxic relationship; self- awareness; hope. The unique theme that emerged in the participants was a complex form of violence in the second participant which was influenced by the duration of the relationship including physical, psychological, economic violence and other things. The findings in this study can be a lesson especially for people who are dating to be more aware of the health of the relationship that is being undertaken.

Abstract

Deviant and negative behavior that we often encounter in children aged 2, 3 to 5 years is also called aggressive behavior. This attitude tends to cause harm to others if this behavior has shown an attitude of hurting or physically attacking. Internal and external factors can be the cause of a child behaving aggressively. Therefore, aggressive behavior can be reduced using certain techniques or methods, one of which is the fading technique. The purpose of this study was to reduce aggressive behavior in early childhood using the fading technique. The research design used in this study was Single Subject Design (SSD) or research with a single subject. The data collection technique used in this study used the observation technique with behavioral tally recording. In the study, 10 intervention sessions were carried out for 7 days with the results of a low aggressiveness categorization with a total score of 54 in the range of 52.5 <X ≤ 67.5. So it can be concluded that there is effectiveness in implementing the fading technique in an effort to minimize aggressive behavior.
