Abstract. Zahra U, Kartika Y, Batubara I, Darusman LK, Maddu A. 2016. Short Communication: Screening the potency of . Zingiberaceae is a family of plant with antioxidant, anticancer, and antiaging activities. The use of the leaves part of this family has never been explored. Therefore, the aim of this research is to evaluate the antioxidant and antiaging activities of some Zingiberaceae's leaves. The species of Zingiberaceae used in this study are Alpinia galanga (L), Curcuma aeruginosa Roxb, Curcuma longa L, Curcuma zedoaria, Curcuma xanthorrhiza Roxb, Boesenbergia rotunda (L.), Elettaria cardamomum, Zingiber zerumbet, Zingiber officinale Roscoe, and Zingiber purpureum Roscoe. Leaves were extracted with 2 different solvents sequentially: ethyl acetate and methanol. Total phenolic and flavonoid contents of the extracts were determined spectrophotometrically. Antioxidant activities were tested by using DPPH (2,2-diphenyl-1-picrylhydrazyl ) and ABTS (2,2'-azino-bis-3-ethylbenzothiazolin-6-sulfonic acid), whilst antiaging activity was tested by using antiglycation method. The results showed that the flavonoid content of the extracts were in the range of 0.83-25.17 g QE/100 g extract with total phenolic content ranging from 9.80-91.71 GAE mg/100 mg extract. The methanol extract of Curcuma xanthorrhiza displayed the highest antioxidant capacity in the DDPH (IC 50 282.35 mg/mL) and TEAC (10.08%) assays, followed by the ethyl acetate extract of C. longa, ethyl acetic extract of C. xanthorrhiza and methanol extract of Z. officinale, while the most active antiglycation is the methanol extract of Z. officinale (IC 50 203.85 mg/L).

Losing both parents due to divorce or death is a traumatic incident that produces a source of stress in life. This will be bad for the person's life since it might create a sense of loneliness, a grave need for affection, and financial problems. Individuals need an ability to overcome problems called resilience. Resilience is a capacity to respond soundly and productively when facing misery or traumatic events. Subjects in this study experienced trauma from parental divorce and death of both parents. When both parents were still alive, the subject never received attention from his father since he had remarried while his mother was forced to work abroad to fulfill their financial needs. The subject was raised by his grandparents with a strong upbringing pattern and lacked the support for achievement. However, the subject managed to grow to be an independent adult and survive the difficult conditions suffered while still managed to be whatever he wants without harming others. The purpose of this study is to investigate the resilience dynamics of a child experiencing parental divorce and death. This research uses phenomenology approach. Subject in this study consisted of one person based on typical case sampling. The typical cases discussed here are divorce and death of both parents. Data is collected using semi-structured interview method and then analysed using thematic analysis.

In accommodating coffee seed production, coffee cherry as the main ingredient was collected from personal farms. Nonetheless, as the company's external condition grows, this strategy is no longer appropriate to keep PT Golden Malabar Indonesia growing and developing in current condition in which the consumption rate of coffee has increased and lifestyle has shifted. The main purpose of this research was to formulate strategy development of Arabica coffee processing business. The analysis tools utilized to examine the company's internal and external conditions included the matrices of Internal Factor Evaluation (IFE), External Factor Evaluation (EFE), and Internal-External (IE). The analysis tool used to determine the appropriate strategy for the company was Quantitative Strategic Planning Matrix (QSPM). The total score of IFE matrix of PT Golden Malabar Indonesia was 3.0507 indicating its strong internal position. The total score of EFE matrix of PT Golden Malabar Indonesia was 2.0160 indicating the lack of response to the opportunities and threats outside the company. The position of IE matrix of PT Golden Malabar Indonesia is in region IV in which the company is growing and developing its Arabica coffee processing industry and it is significantly appropriate to conduct integrating strategy. The first priority strategy is in accordance with QSPM analysis i.e. PT Golden Malabar Indonesia is encouraged to perform backward integration by building connection with coffee cherry distribution partners/agents.

The quality of lesson plans are one of the factor determining success of the learning process in schools. One element of the 2013 curriculum transformation is 21st century skills, namely higher order thinking skills integration in mathematics learning. Basically, to get HOTS thoroughly mastered by the teacher, this later must be trained systematically starting from the planning stage. At the planning stage, the teacher is required to prepare a Learning Implementation Plan (RPP). This study aims to determine the results of analysis of class VIII mathematics lesson plans based on HOTS, and find out what obstacles experienced by mathematics teachers in the preparation of HOTS-based RPP. These problems were investigated through field studies conducted at junior high school (SMP) Negeri 1 Sukoharjo using the qualitative research approach that is survey research method. This study involved 2 grade VIII mathematics teachers. Data were obtained through various data collection techniques, including observation, structured and unstructured interviews, and documentation. Data were analyzed by phenomenology approach and descriptive analysis. Then the data are tested for validated through data triangulation. From the results of the analysis, there were 2 (two) answers to the problem statement. First, RPP is not fully based on HOTS, it could be seen in the selection of verbs in the preparation of indicators still at lower levels of order thinking skills. Secondly, the obstacles encountered by teachers in the preparation of lesson plans included the fact that HOTS-based 2013 curriculum training was only felt by some mathematics teachers, the distribution of books was too late, teachers felt that the understanding of HOTS was insufficient. They stated that compiling HOTS-based 2013 curriculum plans was not easy for them, the school only gives a syllabus. Through this research, it is hoped that all mathematics teachers in general and mathematics teachers at Sukoharjo Middle School 1 in particular can learn from the results of this HOTS-based lesson plan. So that in the future, teachers will be increasingly encouraged to improve their quality and improve the quality of education in Indonesia.
