Muhamammad Amin, Salman Bintang, A. Sutopo
This study aims to find the attributes of soft skills both generic and specific that are relevant to be integrated in the lecture program in the Electrical Engineering Education. The soft skills attribute found is expected to be a supplement in lecture activities in order to produce graduates who have simultaneous competence between knowledge, attitudes, and skills. The data collection methods were carried out by: (1) identifying the types of attributes of soft skills based on local culture, which originated from 6 pillar of unimed character education, as well as attributes derived from the results of international studies; (2) conduct studies and groupings of all attributes that are generic and specific; (3) identify the characteristics of the course, especially those relating to the objectives and plans of lecture activities; (4) conduct a study of the relevance between the objectives and activities of lectures with attributes that can be integrated. The results show that there are 73 attributes that are generic and 56 that are specifically relevant to be mapped, distributed, and trained in each subject. Soft skills that will be trained in the first year are distributed in 22 courses, in the second year 22 courses, and in the third year are distributed in 18 courses.

Synthesis of A and X Zeolites from Non Magnetic Ash of Rice Husks Through the Hydrothermal Process in the Alkaline Bases Condition 碱基条件下以稻壳非磁性灰为原料水热法合成A、X型沸石
I. Jahro, A. Nugraha, N. Nurfajriani
In the general, rice mills produce rice, husks and brand around 72, 20 and 8 % respectively. The burning of rice husks produce ash around 18 %. Ash of rice husks contain silica which is zeolite-forming mineral around 88%. The purification ash of rice husks was conducted through a magnetic separation process using a bar magnet in water. Magnetic separation process produce 92.36 % non magnetic ash of rice husks and 5.64% impurities magnetic. The synthesis of zeolite from non magnetic ash of rice husks through hydrothermal process in an alkaline condition. It was carried out by starting process of forming sodium silicate and aluminate compounds through the reaction of non magnetic ash of rice husks with Al2O3 and NaOH in water accompanied by stirring at 600 rpm in the room temperature for 10 hours. Then the results of reaction was refluxed at 70C for 3 hours so that a mixture of gel was produced. After being stored for 12 hours or more at room temperature, the mixture of gel was refluxed again at 100C for 7 hoursuntil A-zeolite was produced. However, the production of X-zeolite which the mixture of gel was refluxed at 120C for 8 hours. The results of FT-IR and XRD charaterization showed that the A-zeolite has infrared absorption bands in the wave number region of 426.26, 603.24, 1000 cm-1 and diffraction peaks at 2 angles of 12.42, 17.65, 21.63, 28.70 and 33.51 degrees. Whereas the X-zeolite showed infrared absorption bands in the wave number regions of 440.70, 606.44, 745.14, 1007.88 cm-1 and diffraction peaks at 2 angles of 12.34, 17.51, 21.53, 27.90, 28.50 and 33.22 degrees.
一般来说,碾米厂生产的大米、稻壳和品牌分别约占72%、20%和8%。稻壳燃烧产生18%左右的灰烬。稻壳灰分中含有二氧化硅,二氧化硅是沸石形成矿物,约占88%。利用条形磁铁在水中对稻壳灰分进行了提纯。磁选过程产生的稻壳非磁性灰占92.36%,磁性杂质占5.64%。以稻壳无磁性灰为原料,在碱性条件下水热法合成沸石。采用稻壳非磁性灰与Al2O3和NaOH在水中反应生成水玻璃和铝酸钠化合物的起始工艺,并在室温下以600转/分搅拌10小时。然后将反应结果在70℃回流3小时,制成凝胶混合物。在室温下保存12小时以上后,再次在100℃下回流7小时,直至生成a型沸石。而x -沸石的生产,凝胶混合物在120℃回流8小时。FT-IR和XRD表征结果表明,a型沸石在426.26、603.24和1000 cm-1的波数区有红外吸收带,在12.42、17.65、21.63、28.70和33.51度的2个角度处有衍射峰。而x -沸石则在440.70、606.44、745.14、1007.88 cm-1的波数区和12.34、17.51、21.53、27.90、28.50和33.22度的2个角度处显示出红外吸收峰。

The Improvement of Student Communication and Mathematical Disposition Ability Through Problem Based Learning Model at UNIMED FMIPA Students 以问题为基础的学习模式对联华FMIPA学生沟通及数学处理能力的提升
G. I. D. Purba, E. Surya
The active involvement of students in learning must be supported by providing special activities that are student-centered so that they can do "doing math" to find and build mathematics facilitated by lecturers. One aspect of "doing math" is to improve mathematical communication skills. The existence of communication skills will certainly bring students to a deep mathematical understanding of mathematical concepts.In addition to mathematical communication skills, an attitude that must be possessed by students is needed, including appreciating the beauty of mathematics, having high curiosity and learning mathematics. With such an attitude, students are expected to develop mathematical abilities, use mathematics to solve problems faced in their lives, and can develop mathematical dispositions.This research conducted on students of FMIPA with the aim of: (1) knowing students' mathematical communication skills taught by using problem based learning learning model and talking learning model; (2) knowing the differences in students' mathematical disposition abilities taught using Problem Based Learning model and talking learning model; (3) produce a mathematical learning device in the form of an appropriate LAS used to improve students' mathematical communication; (4) produce teaching materials in the form of textbooks with appropriate problem-based learning model used to improve students' mathematical communication
必须通过提供以学生为中心的特殊活动来支持学生积极参与学习,使他们能够在讲师的帮助下“做数学”来发现和建立数学。“做数学”的一个方面是提高数学沟通能力。沟通技巧的存在一定会使学生对数学概念有深刻的数学理解。除了数学沟通能力之外,学生还必须具备一种态度,包括欣赏数学之美,有高度的好奇心,学习数学。有了这样的态度,学生就能发展数学能力,用数学来解决生活中遇到的问题,并能发展数学性格。本研究以FMIPA学生为研究对象,旨在:(1)了解基于问题的学习模式和谈话式学习模式对学生数学沟通能力的影响;(2)了解问题型学习模式与谈话型学习模式在学生数学倾向能力方面的差异;(3)以适当的LAS形式制作数学学习工具,用于提高学生的数学交流;(4)以教材的形式制作教材,采用适当的问题学习模式,提高学生的数学交流能力

Experimental and Performance Assessment of Indonesian Biomass-Fired Based Stove with Internal Air Box using Coconut Shell 印尼椰壳内气箱生物质燃烧炉的试验与性能评价
J. Simanjuntak, E. Daryanto, B. Tambunan, Lisyanto Lisyanto, R. Silaban, A. Putranto
This paper presents an integrated performance evaluation of in-lab manufacturing own designed prototype biomass fired-stove used coconut shell as feedstock. Two different stoves in terms of air required for combustion supply mode;(1) external air box (EAB), (2) internal air box (IAB) mode were tested and assessed with respect to the following performance indicator such as water time to boil, specific fuel consumption, and thermal efficiency. The stoves tested were the forced draft modified rocket-stove types with a battery mini fan-assisted to induce draft to force the controlled air for combustion requirement into the stoves. Flame temperature wasrecorded and displayed using K-type thermocouple and thermometer indicator respectively. Specific calculated using the water boiling test (WBT 4.2.3) version protocol. Results showed that the internal air box (IAB) mode has higher thermal efficiency (38 %), specific fuel consumption (2.5 kg/h), and flame temperature (500 0C) than external air box (EAB) mode. However, the thermal output of the EAB (2.3 kW) was reached higher compare to IAB mode. The findings were used to improve the current biomass fired-stoves further that usually used for heating and cooking applications in rural communities.
本文介绍了以椰子壳为原料自行设计的生物质燃烧炉的综合性能评价。对两种不同的炉具(1)外风箱(EAB)、(2)内风箱(IAB)模式的燃烧供气所需空气进行了测试,并对水沸腾时间、比燃料消耗、热效率等性能指标进行了评估。测试的炉具是强制通风改进的火箭炉具类型,带有电池迷你风扇辅助诱导通风以迫使燃烧所需的受控空气进入炉具。用k型热电偶和温度计分别记录和显示火焰温度。具体计算采用水沸腾试验(WBT 4.2.3)版本协议。结果表明,内风箱(IAB)模式比外风箱(EAB)模式具有更高的热效率(38%)、比油耗(2.5 kg/h)和火焰温度(500℃)。然而,与IAB模式相比,EAB模式的热输出(2.3 kW)达到更高。研究结果用于进一步改进目前通常用于农村社区取暖和烹饪的生物质燃灶。

Two different stoves in terms of air required for combustion supply mode;(1) external air box (EAB), (2) internal air box (IAB) mode were tested and assessed with respect to the following performance indicator such as water time to boil, specific fuel consumption, and thermal efficiency. The stoves tested were the forced draft modified rocket-stove types with a battery mini fan-assisted to induce draft to force the controlled air for combustion requirement into the stoves. Flame temperature wasrecorded and displayed using K-type thermocouple and thermometer indicator respectively. Specific calculated using the water boiling test (WBT 4.2.3) version protocol. Results showed that the internal air box (IAB) mode has higher thermal efficiency (38 %), specific fuel consumption (2.5 kg/h), and flame temperature (500 0C) than external air box (EAB) mode. However, the thermal output of the EAB (2.3 kW) was reached higher compare to IAB mode.
