Abstract

This study aims to analyze the relationship of compressive strength of concrete with iron powder mixture from lathe waste by 10% and alum variation by 0%, 5%, 10%, 15%, 20% and 25%. The method of this study is to compare the compressive strength of normal concrete with the compressive strength of concrete variations of iron powder and alum. The percentage of iron powder of 10% and the percentage of alum of 0% experienced a decrease in the compressive strength value against normal concrete by 8.7%, which used an iron lathe of 10% and alum of 5% experienced a drastic decrease against the compressive strength of normal concrete by 30.4%. It can be concluded that 10% iron lathe impersonation as a substitution of fine aggregates and variations of alum of 0%, 5%, 10%, 15%, 20% and 25% as substitutions of coarse aggregates lead to a decrease in the compressive strength value of concrete

Abstract

Early childhood education at the kindergarten (TK) level is an important foundation for children's cognitive, social, and emotional development. The availability of adequate facilities and infrastructure and educational learning media greatly influence the quality of early childhood learning. This community service activity aims to support the improvement of the quality of education at TK Cempaka II through three main focuses, namely the provision of batik dip learning media as a means of artistic expression and cultural introduction; the provision of educational play tools such as puzzles and letter blocks for children's cognitive stimulation; and renovation of damaged school floorboards to create a safe and comfortable learning environment. The results of the activity showed an increase in children's participation and enthusiasm in learning activities, an increase in community understanding of the importance of educational facilities (from 47% to 53%), and the creation of a more appropriate learning space. This activity proves that simple but targeted interventions/focuses can have a real impact on supporting the quality education process for early childhood.

Abstract

This study aims to: (1) identify the need for developing pop-up scrapbook learning media to improve the basic literacy skills of children aged 5–6 years; (2) describe the design of pop-up scrapbook learning media for improving basic literacy skills of children aged 5–6 years; (3) examine the validity and practicality of pop-up scrapbook learning media; and (4) determine the effectiveness of pop-up scrapbook learning media in improving the basic literacy skills of children aged 5–6 years. The research employed a Research and Development (R&D) method using the ADDIE development model, which consists of analysis, design, development, implementation, and evaluation stages. Data were collected through interviews, observations, and questionnaires. The results show that: (1) the initial analysis indicates that children’s basic literacy skills are still relatively low, and teachers strongly support the development of innovative learning media to improve literacy skills among children aged 5–6 years; (2) the design of the pop-up scrapbook learning media was developed through several stages, including needs analysis, media production, preparation of a media user guide, teacher response questionnaires, and observation sheets for assessing children’s basic literacy skills; (3) the validation results from expert validators indicate that the pop-up scrapbook learning media is categorized as very valid and suitable for classroom implementation, while the practicality assessment by the Class B1 teacher places the media in the very practical category; and (4) the effectiveness test based on pre-test and post-test results demonstrates a significant improvement in children’s basic literacy skills after the implementation of the pop-up scrapbook learning media. Therefore, the developed media is considered highly effective for use in classroom learning to enhance the basic literacy skills of children aged 5–6 years.

Abstract

Seiring dengan kemajuan zaman, teknologi di bidang konstruksi bangunan juga mengalami perkembangan pesat, termasuk teknologi beton, hampir pada setiap aspek kehidupan manusia selalu terkait dengan beton. Pemakaian bahan tambah sudah banyak dilakukan dalam proses campuran beton. Berdasarkan hal tersebut, maka penelitian ini bertujuan untuk mengetahui peningkatan kuat tekan optimal beton dengan bahan tambah serbuk arang briket dan larutan gula pasir pada umur 28 hari. Pada penelitian ini menggunakan persentase variasi serbuk arang briket 12,%, 15%, 17,%, 20%, 22,% dan bahan tambah larutan gula pasir 0,20% dari berat semen. Tinjauan analisis penelitian ini adalah kuat tekan, dengan benda uji silinder beton berdiameter 15 cm dan tinggi 30 cm. Metode perencanaan campuran beton menggunakan metode SNI. Kuat tekan optimal beton terdapat pada variasi serbuk arang briket 17% dan larutan gula pasir 0,20%, yaitu sebesar 31,84 MPa atau meningkat 50,84% dari beton normal. Adapun Penambahan gula pasir pada campuran beton dengan dilarutkan pada air yang digunakan sebagai bahan tambahan sehingga larutnya lebih merata dibandingkan dengan mencampur langsung pada semen ataupun kerikil. Berdasarkan penelitian didapatkan kesimpulan hasil pengujian Vicat aparatus waktu ikatan awal semen adalah penambahan larutan gula pasir 0,20% memundurkan ikatan awal hingga 24 jam.

Abstract

Permasalahan mengenai sampah plastik di Indonesia merupakan isu klasik yang masih menjadi tantangan yang sulit diatasi. Kebiasaan penggunaan plastik oleh masyarakat, terutama kantong plastik, masih umum dan seringkali berujung pada akumulasi limbah di lingkungan sekitar. Sampah plastik tersebut memiliki potensi untuk menyebabkan masalah banjir apabila menumpuk di dalam saluran drainase. Penelitian ini bertujuan untuk memanfaatkan sampah kantong plastik sebagai salah satu bahan campuran beton pada saluran drainase pracetak. Sampah plastik ini digunakan sebagai substitusi agregat kasar dalam campuran beton dengan variasi persentase mulai dari 10% hingga 50% dari jumlah agregat kasar konvensional. Target kualitas beton yang diharapkan adalah mencapai kelas mutu beton II, dengan kuat tekan antara 16 hingga 24 MPa. Dalam penelitian ini akan menganalisis penerapan konsep ekonomi sirkular dalam memanfaatkan sampah plastik. Melalui penelitian ini, diharapkan memberikan nilai ekonomis bagi sampah plastik dan dapat dijadikan sebagai bahan alternatif dalam campuran beton. Konsep ini sejalan dengan program jangka menengah pemerintah Republik Indonesia (RPJMN) yang bertujuan untuk mengembangkan pembangunan berkelanjutan dengan emisi karbon rendah.
