Abstract

The implementation of the multisensory learning approach offers an alternative method to enhance students' writing skills and overall learning outcomes in the Indonesian language subject. After conducting observations, it was discovered that the third-grade students at SDIT As-Salafiyah had low learning outcomes and writing skills in the Indonesian language subject for the 2021/2022 academic year. The inadequate understanding of suggested sentences by students and suboptimal learning management by the teacher were identified as the main causes for these low outcomes. This study employed Classroom Action Research (CAR), which comprised four components: Planning, Action, Observation, and Reflection. In the first cycle, student learning outcomes reached 52.38%, and in the second cycle, it increased to 85.71%, indicating that the mastery of learning outcomes had achieved the expected classical completeness of 80%. In terms of writing skills, the first cycle yielded a score of 1280 with a percentage of 60.95%, indicating a moderate level of proficiency. However, in the second cycle, the score rose to 1900 with a percentage of 90.48%, indicating a high level of proficiency. The teacher's activity observation sheet during the implementation of the multisensory learning approach showed a 62% rating in the first cycle, which improved to 86% in the second cycle, indicating a very good performance. Therefore, it can be concluded that the application of the multisensory learning model effectively enhances students' learning outcomes and writing skills.

Abstract

This research was conducted using the classroom action research (CAR) method. The progress in learning and storytelling skills is still below the Minimum Completeness Criteria and success indicators. The study included 142 students from SDN 2 Tanjungsari, ranging from grade I to grade VI. 36 sixth-grade students were part of the sample, with an equal number of males and females. The researcher collected data using tests and observations. The research instruments were observation sheets and test sheets. The analysis techniques used were qualitative and quantitative analysis. The results of this study showed that the students' learning outcomes in cycle I had a mastery level of 27.78%. In cycle II, there was an improvement in student learning outcomes with a mastery level of 52.78%. In cycle III, the mastery level reached 83.33%. This indicates that the students' learning outcomes had met the applied mastery criteria of 80%. The study also observed students' learning activities. In cycle I, the students' activities scored 19 with a percentage of 1.58%, which was still categorized as poor. In cycle II, there was an improvement in students' learning activities with a score of 27 and a percentage of 2.25%, categorized as moderate. In cycle III, students' learning activities had a score of 41 with a percentage of 3.42%, which was categorized as good. Research using Problem-Based Learning can enhance learning outcomes and student engagement in Social Studies for fourth-grade students at SDN 2 Tanjungsari in Indramayu District.

Abstract

This research aims to determine the characteristics of deterjen with the surfactant Methyl Ester sulfonate (MES), the addition of Garam and ecoenzyme additives. The research was carried out by reacting MES surfactant with Garam in concentrations of 0%, 5%, 10%, 20%, 30% and 40% of the weight of MES. Ecoenzyme is added to the reactor when the temperature of the washing soap has reached 300C. The reaction was carried out in 6 reactors and the parameters observed were pH, color, aroma, viscosity and density. The research results showed that the reactor H4 with a Garam concentration of 20% of the MES weight showed results that were close to the quality of soap referred to by the government (SNI). AbstrakPenelitian ini bertujuan untuk mengetahui karakteristik deterjen dengan surfaktan Methil Ester sulfonat (MES), penambahan Garam dan aditif ecoenzim. Penelitian dilakukan dengan mereaksikan surfaktan MES dengan Garam dalam konsentrasi 0%, 5%, 10%, 20%, 30%, dan 40% dari berat MES. Ecoenzim ditambahkan ke dalam reaktor ketika suhu deterjen sudah mencapai 300C. Reaksi dilakukan dalam 6 reaktor dan parameter yang diamati adalah pH, warna, aroma, viskositas, dan densitas. Hasil penelitian menunjukkan bahwa pada reaktor H4 dengan konsentrasi Garam 20% dari berat MES menunjukkan hasil yang mendekati kualitas deterjen yang dirujuk oleh pemerintah (SNI).

Abstract

Penelitian ini bertujuan untuk mengetahui pembentukan mamaenzim (scoby) dari fermentasi aerobik pengolahan limbah kulit buah dengan variasi penambahan gula.  Komposisi bioreaktor mengikuti kaedah pembuatan ecoenzyme, gula : bahan organik : air = 1 : 3 : 10.  Variasi penambahan gula sebanyak 0%, 10%, 20%, dan 30%  dari komposisi ratio gula  ecoenzyme.  Fermentasi dilakukan dalam 5 buah bioreakor. Fermentasi dilakukan selama 20 hari dengan parameter yang diamati adalah pH, karakteristik selulosa, dan keadaan medium bioreaktor.  Hasil penelitian menunjukkan pH awal pada angka 5 dan pH akhir menunjukkan angka 4 pada minggu ke – 4.  Mamaenzyme (Scoby) yang dihasilkan pada T3 dengan penambahan gula 20% menunjukkan keadaan dengan warna bening, kekenyalan, dan ketebalan yang lebih merata dibanding dengan bioreaktor T1, T2, T4, dan T5 (tidak terbentuk mamaenzim).

Dengan model pembelajaran Contextual Teaching and Learning. Penelitian dilaksanakan dengan 3 siklus, dan di setiap siklusnya terdiri atas perencanaan, pelaksanaan, pengamatan, dan refleksi. Dengan indikator keberhasilan keberhasilannya adalah 80% dari 26 peserta didik yang harus tuntas. Dari hasil penelitian menunjukan bahwa melalui model pembelajaran Contextual Teaching and Learning (CTL) pada mata pelajaran IPA khususnya materi tentang ayo cintai lingkungan dapat meningkatkan hasil belajar peserta didik. Hal ini terbukti dengan adanya peningkatan pada hasil belajar yang dilakukan, dari pra siklus peserta didik yang telah mencapai indikator keberhasilan hanya sebanyak 15,23%, kemudian meningkat pada siklus I menjadi 46,15%, pada siklus II naik menjadi dan 73,08%, Kemudian pada siklus III mencapai  88,46% peserta didik yang telah mencapai indikator keberhasilan.
