Abstract

The increase in the number of road construction projects has led to an increase in the need for road pavement materials (aggregate and asphalt). Currently it takes about 1.6 million tonnes/year of asphalt, as well as aggregate. Seeing these conditions, it is necessary to anticipate the use of waste or natural resources that have not been utilized optimally. In this study, fly ash (PLTU waste) was used as aggregate and Asbuton (Buton Island rock asphalt) was used as a binder for the asphalt mixture. As an effort to save energy, the stirring system is cold. Based on the volumetric characteristics of the artificial coarse aggregate, it only meets the specifications for the VMA value, while the VIM and VFB values have not been met. The mechanical properties (stability and flow values) of the cold asphalt mixture on the replacement of natural aggregate with 25% artificial aggregate met the requirements, but did not meet the Marshall Quotien requirements

Abstract

Fulfillment of balanced nutrition at 1000 HPK is very important for children. Inadequate nutrition will have an impact on the growth and development of children. This is often referred to as stunting. Especially in the current era, the government gives responsibility to BKKBN in reducing the number of stunting at birth that occurs in Indonesia. The purpose of this study was to find out the methods of stunting counseling carried out by BKKBN for pregnant women in preventing babies with stunting. This research was conducted using a descriptive qualitative method. Respondents in this study were BKKBN extension workers in Tanjung Pura District. The research results obtained were counseling methods carried out by the BKKBN for pregnant women in preventing babies with stunting, namely using the discussion method. This method is effective in providing understanding to pregnant women about stunting and its prevention. However, prevention cannot be done only through counseling, it must be adjusted again to the conditions and situation of pregnant women.

Abstract

This research aims to evaluate students' sustainability awareness and engagement and to analyze students' perception of the ESD Project in Biology lessons at an Indonesian Senior High School. This study uses a Mixed Method research design combining quantitative and qualitative research methods. The participants were Year X students of a Senior High School in Jakarta in the 2022/2023 academic year. Survey, journal of reflection, semi-structured interview, observations, and documentation, were used to collect data. Finding: This research found that ESD Project in biology lessons develops Indonesian students' sustainability awareness and engagement. Students change their mindset from being unconscious to become more concerned with environmental issues. Several evidence of the consciousness in this research includes applying sustainability in the daily practice, doing real action by creating campaign videos. The awareness is also shown by their beliefs, values, and judgments in their reflective journal, including developing environmental literacy, changing into pro-environment, and positive attitude to protect the environment. Secondly, PjBL learning model in Biology lessons is meaningful for students by stimulating their cognitive and behavioral engagement. The most popular activity of the ESD Project is creating the design of clothes from waste. The implementation of ESD Projects has some challenges such as time consuming, and low self-regulation among Indonesian high school students. Implications for research, practice, and policy are discussed.

Abstract

Purple yam tuber is known to contain a lot of bioactive components useful for human health. This study was conducted to utilize the tuber in form of purple yam flour for crackers processing and to understand the effect of purple yam flour concentration on the characteristics of crackers.  A completely randomized design was applied using several concentrations of purple yam flour (0, 10%, 20%, 30%, 40%, and 50%) and 3 replications. The concentration of purple yam flour affects volume expansion, color values (L*, a*, and b*) and anthocyanin content of the crackers, but did not affect its water content and texture. The higher concentration of purple yam flour decreased volume expansion, L*, b*, and overall acceptance of the crackers, but increased the anthocyanin content and a* values.  This research proposes that 30% purple yam flour shall be applied to partly substitute wheat flour in crackers processing.  At this concentration, crackers were accepted by the panelist (like it slightly) and has hardness value 287.2 gF, L* 70.35, a* 11.12, b* 20.18, 2.5% water, and anthocyanin content 179.6 mg cyanidin3-glucoside equivalent/g.
