Abstrak
Gas O2 dalam reaksi antara Na2SO3 dan O2 mempunyai kecenderungan untuk cepat naik meninggalkan cairan sehingga konversi reaksi yang diperoleh rendah. Untuk itu perlu diupayakan menghambat laju O2 segar agar tinggal lebih lama dalam cairan. Adanya penambahan padatan CaCO3 dalam reaksi ini diharapkan dapat menghambat laju O2 dalam cairan sehingga dapat meningkatkan konversi reaksi.
Percobaan dilakukan dalam kolom terbuka berbentuk silinder sebagai reaktor. Kolom diisi dengan Na2SO3 yang sudah dilarutkan dalam air dan CaCO3 dengan jumlah tertentu dan divariasikan. Gas O2 dengan laju alir 1 liter/menit dan tekanan 1,01 atm, digelembungkan melalui dasar kolom. Metode percobaan yang digunakan adalah tidak tunak, yaitu dengan mengamati perubahan konsentrasi Na2SO3 dalam kolom. Percobaan dihentikan pada waktu yang telah ditentukan.
Hasil percobaan ini menunjukkan bahwa semakin besar jumlah padatan CaCO3 yang ditambahkan, maka konversi reaksi antara Na2SO3 dan O2 semakin besar. Konversi yang diperoleh dari percobaan ini untuk kisaran penambahan CaCO3 dan Na2SO3 adalah 0 – 20 gram serta 10 – 40 gram adalah 3,3047 – 47,7632 %
THE EFFECT OF USING THINK ALOUD PAIR PROBLEM SOLVING (TAPPS) ON THE EIGHTH GRADE STUDENTS’ READING COMPREHENSION ACHIEVEMENT AT SMP ISLAM GUMUKMAS JEMBER
No full textReading is one of the crucial and essential aspects in learning a language.
However, based on the preliminary study conducted by doing an interview with Mrs.
U, the English teacher of the eighth grade at SMP Islam Gumukmas Jember, on 14
July 2014, she admitted that the students were still lack of concentration and had
difficulty in comprehending the text. There are many techniques that can be applied
in teaching reading comprehension. One of the techniques that can be applied in
teaching reading comprehension is Think Aloud Pair Problem Solving (TAPPS).
TAPPS is a cooperative learning technique that encourages problem-solving skills by
verbalizing one’s thoughts to a listener. TAPPS is believed to have many benefits in
reading comprehension. Therefore, the researcher was interested in investigating
whether or not there is an effect of using TAPPS strategy on the eighth grade
students’ reading comprehension achievement at SMP Islam Gumukmas Jember.
The population of this research was all groups of the eighth grade students’ of
SMP Islam Gumukmas Jember in the 2014/2015 academic year; they were VIII A,
VIII B, VIII C, and VIII D. The research respondents were determined by cluster
random sampling by lottery. Based on the result of homogeneity test, VIII B was
chosen as the experimental group and VIII C as the control group. The treatment was
given to the experimental group, that was, teaching reading by using TAPPS
technique, while the control group was taught reading using lecturing and Question-
Answer technique.
The primary data of this research were collected from the students’ scores of
reading comprehension test (post-test). The primary data were analyzed statistically by using t-test formula through SPSS (Statistical Package for the Social Sciences)
program. Based on the output of Independent sample t-test, the value of significant
column was 0.043 which was lower than 0.05. Thus, conclusion could be drawn that
there was a statistically significant mean difference between the experimental and
control groups. It means that the null hypothesis (H0) formulated: “there is no
significant effect of using Think Aloud Pair Problem Solving (TAPPS) technique on
reading comprehension achievement of the eighth grade students of SMP Islam
Gumukmas Jember” was rejected. On the other hand, the formulated hypothesis (Ha):
“there is a significant effect of using Think Aloud Pair Problem Solving (TAPPS)
technique on reading comprehension achievement of the eighth grade students of
SMP Islam Gumukmas Jember” was accepted
There were some difficulties that the researcher faced when conducting the
research. Some students were shy to think aloud because the researcher tried to pair
the students randomly. Thus, the students were unable to think aloud effectively.
With regard to that condition, the researcher let the students chose their own partners.
Some students were also unmotivated to do the task given by the researcher and were
very noisy. The researcher then created a competitive atmosphere by giving rewards
to the best pairs who scored the best among the other students. For the noisy students,
the researcher asked them to control their voice.
Based on the result of this research, it was concluded that there was a
significant effect of using TAPPS Technique on reading comprehension achievement
of the eighth grade students at SMP Islam Gumukmas Jember in the 2014/2015
academic year. Knowing the significant effect of using TAPPS technique, it is
suggested to the English teachers, students, and other researchers to have a good use
of TAPPS technique
Analisis Pengaruh Beban Lalu Lintas Terhadap Tingkat Kerusakan Jalan Soenandar Priyo Sudarmo, Kecamatan Prambon, Kabupaten Sidoarjo
Full text linkSoenandar Priyo Sudarmo Road often experiences significant stress due to
high traffic volume and load, particularly from heavy vehicles used for various
industrial activities in Prambon District. Additionally, during the survey, various types
of damage were identified, such as pothole, alligator cracking, and raveling. Based on
this, the author conducted a study to analyze the impact of traffic load on the level of
damage to Soenandar Priyo Sudarmo Road. The primary data used included road
damage data, riding quality, and traffic counting, while the secondary data included
road geometric data and Average Daily Traffic. This study used the Indrasurya and
Dirgolaksono (1990) method to analyze road damage, as this method is an adaptation
of various previous road damage evaluation methods, taking into account road
conditions in Indonesia The effect of traffic load on road damage was analyzed using
exponential regression to identify the non-linear relationship between the independent
variable and the dependent variable. The analysis results showed that the types of road
damage found were quite diverse, including potholes, raveling, alligator cracking,
distortion, transverse and longitudinal cracks, rutting, patching, and edge
deterioration. Based on the analysis per segment, the average damage value per
segment ranged from 18.85% to 45.16%, with riding quality in the RQ 1 to RQ 3
categories. Regression showed that heavy vehicles, particularly ESAL 1.2–22 trailers,
had the most significant impact on road damage with an R² value of 0.905. This study
indicates that traffic load, particularly from heavy vehicles, significantly contributes
to road damage. Based on these results, recommended road maintenance is
categorized into light, moderate, and no maintenance, depending on the condition of
each segment
Konflik Batin Tokoh Utama dalam Novel Alisya Karya Muhammad Makhdlori Kajian Psikologi Sastra
Full text linkWibowo, Bayu Priyo. 2017, "The Inner Conflict of the Primary Figure in Alisya's Novel The work of Muhammad Makhdlori is a literary psychology study". Thesis, Indonesian Literature Study Program, Undergraduate Program, Faculty of Humanities, Diponegoro University, Semarang.
Novel Alisya The work of Muhammad Makhdlori recounts the inner conflict of the main character Alisya against herself and her environment. This novel discusses the reality of human life is closely related to the problems of life that affects the development of psychology. The purpose of this study is to describe the intrinsic elements that exist in Alisya's novel and reveal the personality of Alisya as the main character. The author uses a fictional structure to describe the element of the novel builder (figure and characterization, plot, and background). The author also uses the theory of literary psychology that focuses on psychoanalysis Sigmund Freud to examine the personality of the main character through the structure of personality id, ego and superego.
The result of structural analysis of Alisya's novel contains eleven figures consisting of one main character and ten additional characters; The plot of Alisya's novel is an advanced path; The setting contained in this novel is the setting of time, place, and social.
The result of the analysis of personality structure in outline of Alisya figure has no balance between Id, Ego and Superego. Alisya's id and ego are so prominent that she is incapable of controlling her attitude and behavior. Although initially the more dominant Alisya character shows the aspect id and ego, but superego aspects of the morality of her personality can make Alisya back to the right way.
