Construct the Validity of STEM and Project-based Critical Thinking Skills Test Instruments Using the Rasch Model
Abstract. Students' critical thinking skills are very important abilities in the 21st century. To measure critical thinking skills, a valid and reliable instrument is needed. This article uses the Rasch model to construct an instrument for critical thinking skills on number pattern material whose learning uses STEM PjBL. The development method uses the analysis, design, development, implementation, and evaluation (ADDIE) stages. Data processing uses the Rasch model assisted by the Winstep program. The instrument was tested on 33 public junior high school students in Semarang. The research results include validity, namely the validity test by experts with an average percentage of 92.4% in the very valid category, the quality of the questions in the instrument reliability aspect is good, and the average critical thinking ability of students who use STEM-based and Project Based instruments Learning was 61.46, higher than other classes at 49.79. The critical thinking test instrument is based on STEM and the project needs to be further developed on other materials

Developing a Test of Mathematical Literacy based on STEM-PjBL using ADDIE Model
Mathematical literacy is one of the eminent skills in the learning process in the 21st century. However, the mathematical skills of Junior High School students in Indonesia need some improvement. This study aims to develop a test of mathematical literacy based on the integration of Science, Technology, Engineering, and Mathematics (STEM) and Project-based Learning (PjBL). The study involved research and development using the Analysis, Design, Development, Implementation and Evaluation model (ADDIE). The results showed that the developed mathematical literacy test based on STEM-PjBL is valid and practical to be implemented by the expert validator. Moreover, the construct validity through implementation in the classroom obtained the result that the instrument is valid and reliable. This instrument is expected to be disseminated to the wider population to accustom the students to the problem embedded in project-based learning and STEM activities.

Pengaruh Fortifikasi Zat Besi terhadap Sifat Kimia dan Sensori Biskuit Ubi Kayu yang Disuplementasi Tepung Ikan-Tempe
The prevalence of anemia in pregnant women in Indonesia in 2013 was still high at 37.1%. The impact of anemia on long-term pregnant women causes a decrease in the quality of human resources. Therefore, it is necessary to provide foods with high iron content and which are easily absorbed. Cassava biscuits that have been enriched with Tempe fish flour and fortified Fe are expected to be an alternative to anemia control and pregnant women PEM through a "food-based" approach. The study aims to produce cassava biscuits supplemented with Tempe fish flour and fortified Fe, so that it contains high protein and Fe and has good sensory properties. The experimental design used in the study was Randomized Block Design with 2 factors: type of fortification (F); FeSO4 (F1); NaFeEDTA (F2), and concentration of fortification (K), i.e. 0 ppm (K1); 30 ppm (K2); 45 ppm (K3); 60 ppm (K4); and 75 ppm (K5). The variables observed included water content, Fe content, free fatty acid levels, and peroxide numbers. While sensory properties are texture, fishy smell, metallic taste, and level of preference. The results showed that fortification with 45 ppm FeSO4 was the best treatment that produced biscuits with the best sensory properties. The biscuits have the characteristics of 6.01±0.54% moisture content, 43.69±0.34 ppm db Fe content, 1.17±0.02% free fat acid content, and 9.66±0.76meq O2 / kg peroxide rate. The sensor characteristics are rather crisp texture, less noticeable fishy aroma, less noticeable metal flavor, and rather preferred taste
BERTAHAN DI LINGKARAN DAMPAK ERUPSI MERAPI: KEHIDUPAN SOSIAL-EKONOMI MASYARAKAT PEDESAAN DI KECAMATAN TURI, PAKEM DAN CANGKRINGAN, 1960an-2010
Mount Merapi is the most active volcano on the island of Java, it is very
interesting to be an object of research from different disciplines, one of which is
historical science. Mount Merapi is not only resulting disaster but also giving
benefit for society of around it. The research in this essay is using a historical
perspective in time span 1960 � 2010 and it is placing mount Merapi as natural
phenomena that affect the socio-economic life of society in Turi, Pakem, and
Cangkringan.
This researchis using historical method with five stages: topic selection,
search and collection of resources for both documents and interviews, verification
or criticism of sources that include internal criticism and external criticism to test
the validity and accuracy of the source, interpretation: interpretation and
compilation of facts that are still scattered in chronological order, and the last is
writing in descriptive narrative. The observations is focused on the danger level of
volcanic activity and agricultural production statistics to see the impact of the
volcanic activity of Merapi.
The results of this research is that the volcanic activity of Merapi during
period 1960-2010 brought a significant impact on the socio-economic life of
society. That change can be seen with the growing awareness of education, it also
arises because the increasing economic status of the people, especially those who
have farms Salak in district Turi.The volcanic soil is suitable for crop land Salak,
so the majority of people in the district Turi are planting Salak. Turi became a
major supplier of salak needs in Sleman. Moreover, social change also looked
after the eruption that is the uniformity of status among members of society. They
have a house at the same price and vehicles that are not much different. They
uniformly have a home at the same price and also vehicles that are not much
different. It is resultingnot difference between the upper class, middle and bottom.
Furthermore, in the economic sector, volcanic material is causing changes in the
husbandry: from shepherd changes to cage. Moreover volcanic material also
creates new economic resource for the community. It can be seen, there aremini
museum in former their house which buried vulcanic materials.

PENGARUH KONSENTRASI STPP DAN LAMA PERENDAMAN TERHADAP KARAKTERISTIK PATI KIMPUL TERMODIFIKASI IKATAN SILANG
Kimpul is one type of tubers that is high in carbohydrate content so it can
be used as a source of starch. Natural starch generally still has several
disadvantages. One of method that can be done to overcome these
weaknesses is by modifying cross-linked starch. The objectives of this
study are: 1) to know the effect of STPP concentration on chemical and
physical characteristics of modified kimpul starch; 2) to know the effect of
soaking time on chemical and physical characteristics of modified kimpul
starch; 3) to determine the best combination treatment between STPP
concentration and soaking time on the chemical and physical
characteristics of modified kimpul starches. This is an experimental
research with Randomized Block Design. The factors studied were the
concentration of sodium trypolyphosphate (1, 2 and 3%) and soaking time
(60 and 90 minutes). The variables tested were moisture content, starch
content, amylose content and calcium oxalate content, brightness, swelling
power, sollubility and its amylographic properties. The results showed
that both STPP concentration factors and soaking time affected the
modified chemical and physical characteristics of kimpul starch
crosslinking methods. The chemical and physical characteristics of crossbonded modified kimpul starch increased with STPP concentration and
soaking time used. Modified kimpul starch using 3% STPP concentration
and 90 minutes soaking time had moisture content, starch content, amylose
content, calcium oxalate content, brightness and high swelling power. The
best modified kimpul starch is modified kimpul starch using 2% STPP
concentration and 60 minutes soaking time. It has a water content of
7,88%, starch content of 63,13%, amylose content of 17,28%, oxalate
content of 15,84 ppm, swelling power 15,79 g/g, sollubility 11,55%,
brightness of 44.13, initial gelatinization temperature of 78,75oC, peak
viscosity of 5152.5 cP, hot paste viscosity of 2310,4 cP, breakdown
viscosity of 2815 cP, setback viscosity of 1563 cP and cold paste viscosity
of 3873,5 c
