Vitrification is considered  as the most appropriate technology for HLW treatment.  However, it has constraints, those are processability, economic, and durability. The purposes of  this study are to examine the composition of materials using bottom ash  as an alternative glassfrits for vitrification, to assess waste glass durability of selected glassfrits and analyze the economic advantage of bottom ash utilization as glassfrits. This research was conducted with simulated High Level Waste. Glass–waste was melted at its melting point. Glasses  used in the study were borosilicate glass, bottom ash glass, and bottom ash glass added  B2O3.  Parameters  used  for  selected  glassfrits  are  melting  temperature,  leaching  ratecompressive strength and cost analysis. Selected glassfrits was analyzed using XRD and performed tests to determine the effect of pH on leaching rate. The results indicated that the addition of B2O3 in glass bottom ash reduced the melting temperature. This glass has a density of 2.78 g/cm3 , leaching rate of 6.99 x 10-7. Utilization of  bottom ash as a glassfrits can save 75, 34% of cost. The results of XRD analysis explained that the devitrification formed  a crystalline of Ca-Fe-Al-S-Si-O, Fe+2Fe2 O4+3, Ca-Mg-Fe-Ti-AlSiO. the influence of pH on the leaching rate showed that the highest leaching rate was at acidic condition Keywords: vitrification, chemical durability, mechanical durability, bottom ash

What and why transportation, climate change, and gender are connected?  What is the implication of transportation policy, program and plan (PPP) to gender equality and vice versa? This article aimed to construct it in the context of urban transportation in Semarang City where transportation contributes more than 50% of GHG emissions. This research investigated the relation of transportation, climate change, and gender by interviewing and exploring transportation users through a multistage random sampling. The respondents are divided into urban zones namely inner, suburb, and outskirt with a balanced number of men and women respondents in order to give equal information. The results showed three interesting findings. First, women and men have different travel patterns. Women’s preference for travelling implies more efficient energy consumption. Second, women have a higher dependency on public transport than men due to their limited transportation access (ownership and use). At the household level, men have a dominant role in determining transportation mode, type, and ownership of private vehicles. It influences the choice of transportation mode and the way women ride vehicle. Third, the differences of travel pattern and transportation between men and women implied to GHG emissions contribution. Participation of women in the design of transportation policy, program, and the plan will give a better impact on the transportation system and climate change as well as for women access to transportation.

Physical conditioning was considered as a strong foundation for developing techniques from different fields. The aims of this study was to determine the impact of physical conditioning in parenting students or athletes gymnastic basic skills. The study was a surveyed research. The study sampling was 82 students aged between 18-19 years from Sport sciences, exactly coaching sciences. Data collection methods used checks and measurements of bio motor and gymnastic fundamental skills. Data analysis using correlation and linear regression to predict the future competence. The results showed that: there was significant correlation between the physical conditioning items and gymnastics basics skills, but there is also strong significant linear regression (p: .032.05)  from physical conditioning with basic skill of Gymnastics. The standing balance (r = .728) and broad jump (r = .751) were found more influenced for gymnastic basic skills. There was a great significant different between the pre-test and posttest gymnastic basic skills means with p value .001. The high standard deviation between the items showed the different adaptation of the subjects according to the physical conditioning. In conclusion physical conditioning was found as parenting for developing the gymnastic basic skills.

Physical fitness was an activity or exercise that can accelerate regeneration when performing several exercises or training. This study aimed to examine the physical fitness characteristics of male and female junior wushu players, followed by determining physical performance differences between both groups. The analytical observational study method was implemented to conduct this study using a cross-sectional approach Fifty junior wushu players (male: n= 25, height= 147.78 ± 12.96 cm; female: n= 25, height= 147.78 ± 12.60 cm) participated in this study by conducting some physical fitness tests. The results showed significant differences in the indicators of 20-meters running with a P-value of 0.049, backbend with a P-value of 0.000, and vertical jump P-value of 0.021. Meanwhile, there was no significant difference between male and female wushu players in the T-test, push up, sit up, dan sit reach (P0,05). From the results, it can be said that male players have higher scores in terms of weight, height, speed, and power, while female players have higher scores in terms of flexibility. This study concluded that it can be taken into consideration to optimize training and testing procedures for junior wushu players.

This research examines the importance of coaching to make a breakthrough by providing guidance on an ongoing basis to teachers at SMA Negeri 70 Kebayoran Baru, South Jakarta, with the hope that later it will produce (output) teachers who are able to master how to prepare lesson plans properly and correctly. The results of the study show that continuous guidance can increase teacher motivation in compiling a complete lesson plan. The teacher shows seriousness in understanding and compiling lesson plans, especially after receiving guidance on the development/composition of lesson plans from researchers. This information the researchers obtained from the results of observations when conducting interviews and guidance on the development / preparation of lesson plans for teachers. Next is to show that continuous guidance can improve teacher competence in preparing lesson plans. This can be proven from the results of observations which show that there is an increase in teacher competence in preparing lesson plans from cycle to cycle. In the first cycle, the average value of lesson plan components was 69% and in the second cycle, 83%. So, there was an increase of 14% from cycle I.
