Abstract

Dalam pembuatan sabit dan pisau digunakan material plat baja dan plat besi dengan proses plat baja dimasukan pada sela-sela lipatan plat besi kemudian material ditempa dan quenching. Tahapan quenching terdapat pengolesan air garam yang berperan penting dalam menentukan sifat material sabit. Tujuan dari penelitian ini adalah mencari persentase campuran air garam yang sesuai dengan kebutuhan sifat peralatan tani. Analisis pengolesan air garam menggunakan tiga perbandingan campuran sebesar 10%, 25% dan 40%. Penelitian dilakukan dengan menggunakan uji tarik, uji kekerasan brinell dan foto makro. Secara berurutan dari masing-masing percobaan didapatkan hasil yaitu: dari uji kekerasan diperoleh nilaisebesar 81,5 HRB, 96,5 HRB dan 101,3 HRB, dari uji tarik dan foto makro diperoleh sifat material adalah sifat ulet, sifat keras disertai ulet dan sifat getas. Campuran air garam paling baik sebesar 25% karena memiliki nilai kekerasan tinggi sebesar 96.5 HRB dan memiliki sifat yang keras dan masih memiliki sifat ulet. Kata kunci : alat pertanian, quenching, sifat material.

Abstract

Albumin is used to treat hypoalbumimenia in various diseases. The utilization of albumin raw materials from donor blood that has exceeded the time limit of use could be advantages, which are reducing dependence on imported albumin and could reduce the cost of processing waste blood. The purity and resulting of albumin can be influenced by various parameters including; temperature, pH and ethanol concentration. In this research, the optimization process is conduct using the Simplex Lattice Design method in order to obtain an optimal composition variation of 7 (seven) parameters variation composition to obtain albumin with a high concentration. Albumin is separated by ethanol fractionation method through differences in protein solubility in plasma. Based on Anova test, the 7 (seven) composition variations of the parameters showed significant differences with p = 0.0282 (<0.05) and F test > F table. The evaluation results show that the composition of the 5th composition formula shows the optimal albumin response with temperature parameters -10oC, pH 4.8 and ethanol concentration of 40%. The albumin content obtained with the composition is 53.59 ug. Keywords: Albumin, temperature, pH, ethanol and Simplex Lattice Design

Abstract : Increased Student Class IPS Learning Outcomes Through School Playing Role Assisted Methods School Cafeteria. The purpose of this study is to improve the learning outcomes of IPS as well as describe the steps of role learning model with school canteen media in improving the learning outcomes of IPS students grade 3 SDN 02 Genengadal Purwodadi. Subjects of this study amounted to 16 students consisting of 9 male students and 7 female students. Technique of data collecting using test and observation. The data obtained will be analyzed by giving exposure to detail the average increase of learning outcomes from the cognitive, affective and psychomotor aspects of the students to find out the difference in the value of learning outcomes between cycles. The results obtained in this research that is the increase of learning outcomes IPS grade 3 students SDN 02 Genengadal Purwodadi through the implementation of learning model role play with school canteen media. Step by step model of role play with school canteen media can improve student learning result because in student learning divided into 2 group, then teacher ask student in group to discuss and study play role script, after that teacher invite student to school cafeteria to play role And dialogue according to a given script. Keywords : Learning Outcomes, Role Playing Models With School                    Canteen Media Abstrak : Peningkatan Hasil Belajar IPS Siswa Kelas 4 Melalui Metode Bermain Peran Berbantuan Media Kantin Sekolah. Tujuan penelitian ini adalah untuk meningkatkan hasil belajar IPS serta mendeskripsikan langkah-langkah model pembelajaran bermain peran dengan media kantin sekolah dalam meningkatkan hasil belajar IPS siswa kelas 3 SDN 02 Genengadal Purwodadi. Subyek penelitian ini berjumlah 16 siswa yang terdiri dari 9 siswa laki-laki dan 7 siswa perempuan. Teknik pengumulan data menggunakan tes dan observasi. Data yang didapat akan dianalisis dengan cara memberikan paparan detail kenaikan rata-rata hasil belajar dari ranah kognitif, afektif dan psikomotorik siswa untuk mengetahui selisih peningkatan nilai hasil belajar antar siklus. Hasil yang didapatkan dalam penelitian ini yakni terjadinya peningkatan hasil belajar IPS siswa kelas 3 SDN 02 Genengadal Purwodadi melalui implementasi model pembelajaran bermain peran dengan media kantin sekolah. Langkah-langkah model pembelajaran bermain peran dengan media kantin sekolah dapat meningkatkan hasil belajar siswa karena dalam pembelajaran siswa dibagi menjadi 2 kelompok, kemudian guru meminta siswa dalam kelompok untuk berdiskusi dan mempelajari naskah bermain peran, setelah itu guru mengajak siswa ke kantin sekolah untuk bermain peran dan berdialog sesuai dengan naskah yang telah diberikan. Kata Kunci : Hasil Belajar, Model Pembelajaran Bermain Peran Dengan                     Media Kantin Sekolah

Abstract

The Quran is a guide to life, a source of inner peace for humans. In modern life, characterized by stress, anxiety, and a loss of spiritual direction, the values ​​of the Quran offer a genuine solution. This article examines the concept of peace from a Quranic perspective using a thematic interpretation (maudhu'i) approach. Analysis of several verses shows that peace (as-sakinah and ath-thuma'ninah) is achieved through faith, dhikrullah (remembrance of Allah), tawakkul (trust in God), and a balance between worldly and afterlife aspects. This study utilizes classical and contemporary sources of interpretation, such as those by Ibn Kathir, Quraish Shihab, and M. Yunan Yusuf. The results indicate that the stronger a person's spiritual connection with the Quran, the greater the peace they experience.
