HUBUNGAN KECEPATAN BERJALAN DENGAN KESEIMBANGAN BERDIRI PADA LANJUT USIA DIPANTI WREDHA DHARMA BHAKTI SURAKARTA

Lanjut usia adalah orang yang sistem-sistem biologisnya mengalami perubahan- perubahan struktur dan fungsi dikarenakan usianya yang sudah lanjut. Permasalahan kesehatan lansia wanita lebih kompleks daripada lansia pria. Hal ini disebabkan lansia wanita mempunyai siklus hidup yang lebih rumit. Sebelum memasuki lansia, wanita terlebih dahulu memasuki masa yang disebut menopause dan setahun kemudian memasuki masa yang disebut pasca menopause. Tujuan dari penelitian ini adalah untuk mengetahui hubungan kecepatan berjalan, keseimbangan berdiri satu tungkai pada para lanjut usia di panti. Sampel penelitian ada 48 orang. Penelitian ini merupakan penelitian survei cross sectional. Data yang sudah diperoleh diuji dengan statistik parametrik dengan uji korelasi product-moment. Hasil penelitian diperoleh bahwa terdapat hubungan yang signifikan antara kecepatan berjalan dengan keseimbangan berdiri pada lanjut usia. Hal ini disebabkan nilai Pearson sebesar 0,657 dengan p-value sebesar 0,000, sehingga menunjukkan Ho ditolak (p < 0,05). Demi sempurnanya penelitian, disarankan adanya penelitian lanjutan dengan metode penelitian dan variabel yang berbeda

The Critical Thinking Abilities in Learning Using Elementary Algebra E-Books: A Case Study at Public Universities in Indonesia

The learning Algebra courses are often taught using coventional textbooks. However, the reality of the learning outcomes has not been able to absorb the material to the maximum extent possible, and this is because the textbooks is limited in number so that students only record some of what is taught by the Lecturer. At the same time, electronic books are available free of charge in several world libraries. The purpose of this study is to determine the ability to think critically mathematically through the use of Elementary Algebra electronic books. The study of the method are used a Quasi Experiment with a nonrandomized Pre-test Post-test Control Group Design research design. The study population was all students who took Elementary Algebra in the Department of Mathematics Education, Malikussaleh University, in the Even Semester 2018/2019 academic year. Sample for the study was students of class A1 as an Experiment group using E-books for Teaching, and Class A2 as a Control group with lectures using conventional textbooks. The results showed that the mathematical critical thinking ability of students taught using Electronic books was better than the mathematical critical thinking ability of students who were taught using conventional textbooks. Thus the use of elementary algebra electronic books (E-books) can improve students' mathematical critical thinking skills in learning Algebra

Perempuan Banjar: Kajian Awal Tentang Sejarah Gender Abad XVIII – XX

Selama ini konsep gender perempuan Banjar masih kabur. Hal ini disebabkan oleh tidak adanya penelitian tentang konsep gender dalam budaya Banjar secara historis. Penelitian ini bertujuan untuk memahami kondisi sosial masyarakat Banjar yang membentuk konsep gender abad XVIII-XX dan mendiskripsikan konsep gender perempuan Banjar secara kronologis dalam kurun abad XVIII-XX pula. Penelitian ini menggunakan metode sejarah; heuristik, kritik, interpretasi dan historiografi. Penelitian ini menemukan fakta sosial dalam masyarakat Banjar senantiasa selalu berubah tergantung pada kondisi politik dan ekonomi yang terjadi. Walau demikian, konsep gender perempuan Banjar seakan tidak berubah. Perempuan diberi ruang dan peluang yang luas untuk berperan dalam sektor publik-produktif, tentu dengan tidak melupakan tugas keperempuanannya di rumah tangga sebagai ibu dan isteri. Hal ini menunjukkan bahwa perubahan sosial tidak dapat mengubah konsep gender perempuan Banjar

The Analysis of Students’ Understanding of Electricity Fundamental Concepts

The aim of this research was to analyze students’ understanding of electricity fundamental concepts. The research of subjects are 86 students in physics department of UNG who are taking lectures of Fundamental Physics I in 2021/2022 academic year. Data analysis was conducted based on combination of multiple-choice test results Certainty of Response Index scores. The results show the students' understanding of electricity fundamental concepts which includes sub topics: conduction and induction, relation of electrostatic force and distance, electrostatic force resultant, electric field and electric potential, relation of voltage and electric current in conductor, series and parallel circuit, and placement of ammeter and voltmeter in electrical circuits, are still weak by most students, even many students who choose the false answer but are very sure of the answer. The research recommended further research to examine more intensely and more factually about the causes of student failure in solving fundamental problems of electricity, for example using Predict-Observe-Explain model or structured clinical interviews

Ratu Zaleha 1905-1906: Peran Gender dan Perlawanan Terhadap Penjajah

Abstrak: Penulisan sejarah Banjar selalu saja didominasi oleh tema dan tokoh laki-laki. Oleh karena itu, perlu diimbangi dengan penulisan sejarah dengan tema dan tokoh perempuan agar tercipta sejarah yang androginus. Salah satu tokoh yang layak untuk ditulis adalah Ratu Zaleha, karena perlu diketahui latar belakang konstruksi sosial seorang perempuan yang mempunyai karakter tangguh itu sebagai bahan renungan untuk membentuk perempuan tangguh yang mampu bersaing dengan laki-laki pada masa sekarang. Untuk mengetahui hal itu, maka perlu dilakukan penelitian sejarah dengan melakukan proses heuristik, kritik, interpretasi, dan historiografi serta dibantu dengan pendekatan sosiologi gender. Dari metode sejarah dan pendekatan sosiologi gender itu diketahui bahwa pada tahun 1905-1906, Ratu Zaleha selalu berada di garis depan medan pertempuran sejajar dengan laki-laki seperti Gusti Muhammad Seman, Gusti Muhammad Arsyad, dan Panglima Batur. Adapun sebab Gusti Zaleha mampu melakukan peran gender yang setangguh ini dikarenakan konstruksi sosial berupa bubuhan Pagustian yang selalu siaga perang sejak 1863. Kata Kunci: Ratu Zaleha, Peran Gender, Perang Banjar, Hulu Barito Abstract: The writing of Banjar history has always been dominated by male themes and figures. Therefore, it is necessary to balance it with the writing of history with female themes and figures in order to create an androgynous history. One figure worthy of being written is Ratu Zaleha, as her social construction as a tough woman provides a reflective material to form tough women who can compete with men in today's era. To understand this, historical research needs to be conducted by using heuristic, critical, interpretive, and historiographic processes with the assistance of a gender sociology approach. From the historical method and gender sociology approach, it is known that in 1905-1906, Ratu Zaleha was always at the forefront of the battlefield alongside men such as Gusti Muhammad Seman, Gusti Muhammad Arsyad, and Panglima Batur. The reason why Ratu Zaleha was able to perform such a strong gender role was due to the social construction in the form of bubuhan Pagustian  who have been ready for war since 1863. Keywords: Ratu Zaleha, Gender Role, Banjar War, Hulu Barit

Meminimalkan Miskonsepsi Pada Materi Rangkaian Listrik Dengan Pembelajaran Predict-observe-explain

: Minimizing Misconceptions on the Topic of Electric Circuits by Predict-Observe-Explain Learning. This pretest-posttest control group experiment was aimed to improve students\u27 understanding of the concept and to minimize their misconceptions on the topic of electric circuits. The subjects were se­lected using cluster random sampling from high school students in Gorontalo. The instruments used to collect the data included pretest, posttest and questionnaires. The data were analyzed using t-test. The students\u27 conception profiles were carried out using Certainty of Response Index (CRI) technique. The results show the significant difference in the posttest average and normalized gain average between the experimental and the control classes. The results are supported by the fact that misconceptions in the experimental class are smaller than those in the control class. The application of predict-observe-explain learning is effective to improve the understanding of the concept and minimize the misconceptions

The average increase in power and torque was 9.37% and 8.45%, respectively.  Keywords : Engine performance, water injection, Arduino Un

Role of Self-Efficacy Toward Students’ Achievement in Mathematical Multiple Representation Ability (MMRA)

Various studies showed that there are some points which affect students’ achievement; one of them is mathematics self-efficacy. Self-efficacy is feeling, trust, and confidence of affective behavior of students toward their ability. In learning process, the students find obstacles in solving their problem such as relating one representation to another representation. Previous studies indicated that students’ achievement of mathematical representation ability have obstacles because the students did not understand relationship between concepts, ideas, and materials to be represented. The other studies claimed that the higher students’ self-efficacy, the higher mathematical multiple representation ability (MMRA). It means that self-efficacy has positive correlation with mathematic ability. This article will discuss about role of mathematics self-efficacy toward ability achievement of mathematical multiple representation ability (MMRA) in solving mathematics problem in order to increase students’ achievement

Crystal Forming Rate and Distribution Changes of MCT Content in Palm Kernel Oil Fractionation Product

Palm kernel oil is considered a special oil since it contains medium chain tryglicerides (MCT), especially lauric acid that is easily digested and has a special character as cocoa butter substitutes (CBS). Palm kernel oil fractionation will produce a solid fraction (stearin) and a liquid fraction (olein) with specific characteristics (specialty fat) that the physico-chemical properties are highly dependent on the cooling treatment applied. In this research, 3 kinds of crystallization temperatures (18.0 oC, 19.0 oC, dan 20.0 oC) in various cooling rates and duration of the crystallization process, were examined for its effect on the crystal-forming rate of palm kernel oil and distribution changes of MCT content of fraction resulted. All tracks recorded during the cooling process had to be calculated to predict the crystal-forming rate in the crystallization process. In all cooling treatments, the amount of olein fraction produced decreased and the stearin fraction increased which was equal to the duration of the crystallization process. The setting of crystallization temperature at 18.0 oC produced a stearin forming rate higher than at temperatures of 19.0 and 20.0 oC. Forming rate of stearin (crystal) was contrary to the crystallization temperature and duration of the cooling period but not being affected by initial cooling temperature, initial cooling rate, duration of the cooling process to reach crystallization temperature, and average rate of oil cooling. Percentage of oil crystal-forming at 3 crystallization temperature equals to logarithmic of crystallization duration. The lower the crystallization temperature, the higher the rate of oil crystallization forming. As the increase of stearin produced during crystallization, MCT content was decreasing, but for olein, as the decreasing it during the crystallization period, the distribution of MCT content tends to increase
