Abstract

Mahasiswa dan dosen Program Studi Teknik Sipil Institut Teknologi Sumatera (ITERA) melaksanakan kegiatan pengabdian kepada masyarakat bertema "Cahaya Interaktif" di SD Sekolah Alam Lampung. Kegiatan ini bertujuan untuk meningkatkan pemahaman siswa sekolah dasar terhadap konsep dasar cahaya dan sifat-sifatnya melalui pendekatan pembelajaran yang menyenangkan, interaktif, dan partisipatif. Metode pelaksanaan meliputi penyampaian materi melalui presentasi interaktif, praktik langsung menggunakan alat peraga Kotak Cahaya, serta simulasi digital berbasis web untuk memperkuat pemahaman visual siswa. Guna mendorong keterlibatan aktif, siswa diberikan sistem poin dan hadiah sebagai bentuk apresiasi terhadap partisipasi mereka. Sebagai bentuk keberlanjutan program, alat peraga Kotak Cahaya dihibahkan kepada pihak sekolah untuk mendukung proses pembelajaran sains di masa mendatang. Hasil kegiatan menunjukkan peningkatan signifikan dalam pemahaman siswa terhadap konsep cahaya, yang tercermin dari partisipasi aktif lebih dari 90% siswa dalam eksperimen dan diskusi. Pemanfaatan media peraga dan pendekatan interaktif berbasis teknologi terbukti mampu menciptakan suasana belajar yang menyenangkan, kolaboratif, dan bermakna bagi siswa sekolah dasar.

Abstract

The background of this study is based on the increasing problem of plastic waste in Indonesia, which has a negative impact on the environment. This study aims to evaluate the utilization of Low-Density Polyethylene (LDPE) polymer waste as a substitute for fine aggregate and rice husk ash as a substitute for cement in making Paving blocks using conventional methods. This study will look at the effect of material substitution on compressive strength and water absorption. The experimental process involves shredding LDPE polymer waste, making Paving block mixtures, and testing mechanical properties. The results showed that the addition of LPDE to the paving block mixture would cause a decrease in strength of 0.8632 MPa for every 1% LDPE used. If added with 10% use of rice husk ash, then every 1% use of LDPE will cause a decrease of 0.6425 MPa. For water absorption, there was an increase of 0.11% for every 1% LDPE mixing and 0.23% for every 1% LDPE mixture with 10% rice husk ash. The price obtained from the variation of LDPE usage of 5%, 10%, 15%, 20% plus 10% rice husk ash is cheaper than the price of using standard materials according to the basic price of the Lampung region in 2022. The price difference is 36%, 33%, 29%, 26% respectively. The use of LDPE waste and rice husk ash in the manufacture of paving blocks not only reduces the amount of plastic waste but also has the potential to make a significant contribution to the development of a more sustainable construction industry and supports efforts to reduce plastic waste in Indonesia. Abstrak Latar belakang penelitian ini didasari oleh permasalahan sampah plastik yang semakin meningkat di Indonesia, yang berdampak negatif terhadap lingkungan. Penelitian ini bertujuan untuk mengevaluasi pemanfaatan limbah polimer jenis Low-Density Polyethylene (LDPE) sebagai subtitusi agregat halus dan abu sekam padi sebagai subtitusi semen dalam pembuatan paving block menggunakan metode konvensional. Penelitian ini akan melihat pengaruh dari subtitusi material terhadap nilai kuat tekan dan penyerapan air. Proses eksperimen melibatkan pencacahan limbah polimer LDPE, pembuatan campuran paving block, dan pengujian sifat mekanis. Hasil penelitian menunjukkan bahwa penambahan LPDE pada campuran paving block akan menyebabkan penurunan kekuatan sebesar 0,8632 MPa setiap penggunaan 1% LDPE. Jika ditambahkan dengan 10% penggunaan abu sekam padi maka setiap penggunaan 1% LDPE akan menyebabkan penurunan 0,6425 MPa. Untuk daya serap air , terjadi kenaikan sebesar 0,11% untuk setiap 1% pencampuran LDPE dan 0,23% untuk setiap 1% campuran LDPE dengan 10% abu sekam padi. Harga yang didapatkan dari variasi penggunaan LDPE 5%, 10%, 15%, 20% ditambah dengan Abu sekam padi 10% lebih murah dari harga penggunaan material standar sesuai dengan basic price wilayah Lampung Tahun 2022. Selisih harganya masing - masing adalah 36%, 33%, 29%, 26%. Pemanfaatan limbah LDPE dan abu sekam padi dalam pembuatan Paving block tidak hanya mengurangi jumlah limbah plastik tetapi juga berpotensi memberikan kontribusi signifikan terhadap pengembangan industri konstruksi yang lebih berkelanjutan dan mendukung upaya pengurangan limbah plastik di Indonesia.

Abstract

One type of load that needs to be taken into account in foundation planning is the lateral load. Lateral load is a force that acts perpendicular to the pile, so it has the potential to cause shifting if the pile does not have sufficient capacity to withstand it. The type of foundation used in this analysis is a bored pile foundation with a diameter of 0.8 m and a pile length of 24 m. The results of the interpretation calculations to obtain the value of the ultimate lateral bearing capacity based on the lateral load test data show differences in the values of each method used. The interpretation calculations that have been carried out obtained the ultimate lateral bearing capacity with the Davisson method of 23,800 tons, with the Chin method obtained a result of 26,455 tons, and the Decourt method of 25,894 tons.

Abstract

The Student Dormitory is a gathering place for most new students at ITERA. For disaster mitigation, it is necessary to conduct geophysical and geotechnical surveys. Geophysical and geotechnical surveys are conducted to describe the subsurface lithology. The purpose of this study is to identify the subsurface of the Dormitory building so that it can be determined which buildings have the potential for geological hazards. The methods used are geomagnetic, geoelectric and geotechnical methods. The results obtained are that High and low magnetic anomalies are related to the thickness of the lithology. This is also justified by the results of geoelectric using resistivity cross-sections. The thickness of this lithology is related to the level of building security. TB4 has the highest security based on magnetic and geoelectric data. Meanwhile, TB1 has the lowest security based on subsurface conditions.

Abstract

The construction of a structure on soft soil has the potential for structural failure. This phenomenon occurs because the low bearing capacity of soft soil is accompanied by high compressibility, resulting in large settlements and low stability. This problem needs to be solved by soil improvement. In the Indrapura–Kisaran STA 112 + 500 Toll Road Construction Project, soil will be filled more than the ground's bearing capacity. Therefore, a soil improvement method using a Controlled Modulus Column (CMC) is necessary. The analysis method used in this study uses analytical methods and the finite element method (FEM). The analysis was performed by comparing the bearing capacity and settlement in conditions without improvement (preloading) and with improvement using CMC. The installation of CMC with a spacing of 1 meter, a diameter of 0.42 meters, an LTP thickness of 1 meter, and a concrete quality of 16.41 MPa showed an increase in soil bearing capacity of 30%. The rise in ground bearing capacity also affected soil compressibility, resulting in a reduction of up to 68% in soil settlement. Therefore, installing CMC on soft soil effectively increases bearing capacity and reduces settlement. Ground stability is improved, with the safety factor rising to 2.11.
