Vitrification is consideredÂ as the most appropriate technology for HLW treatment.Â However, it has constraints, those are processability, economic, and durability. The purposes ofÂ this study are to examine the composition of materials using bottom ashÂ 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. Glassâ€“waste was melted at its melting point. GlassesÂ used in the study were borosilicate glass, bottom ash glass, and bottom ash glass addedÂ B2O3.Â ParametersÂ usedÂ forÂ selectedÂ glassfritsÂ areÂ meltingÂ temperature,Â leachingÂ 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 ofÂ bottom ash as a glassfrits can save 75, 34% of cost. The results of XRD analysis explained that the devitrification formedÂ 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.

Data tes bakat diperoleh dari 7 item tes yang terdiri dari tes antropometri meliputi: tinggi badan dan berat badan dan tes fisik meliputi: kelentukan, kekuatan, kelincahan, kecepatan, dan power sehingga satuan skor yang diperoleh bermacam-macam, untuk mengatasi hal tersebut, data kemudian dirubah dalam bentuk t-skor sehingga diperoleh data dengan satuan yang sama. Data t skor lalu diambil rerata kemudian data dikategorikan menjadi 5 kategori sesuai dengan rumus norma aturan yang berlaku. Teknik pengumpulan data yang digunakan adalah tes dan pengukuran, meliputi: tes antropometri dan tes biomotor. Teknik analisis data yang digunakan adalah persentase. Hasil dari penelitian ini adalah mayoritas subjek penelitian cukup berbakat pada cabang olahraga wushu dengan prosentase sebasar 64,81%. Talent identification of wushu in Yogyakarta AbstractTalent identification is an important component in achieving athlete achievement.

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.
