Abstract

Berbagai bahan alternatif diuji guna menghasilkan beton yang bermutu tinggi dengan material yang lebih ekonomis. Pada penelitian ini dilakukan pengujian dengan bahan alternatif ramah lingkungan menggunakan limbah plastik berjenis LDPE sebagai bahan tambah dalam campuran beton. Penelitian ini bertujuan untuk mengetahui karakteristik kuat tekan beton dengan bahan  tambah plastik tersebut. Dalam penelitian ini akan dibuat benda uji silinder dengan variasi komposisi penambahan limbah plastik LDPE 0%, 2,5%, dan 7,5% dari proporsi semen dengan jumlah sampel yang diuji sebanyak 9 buah Dari penelitian yang sudah dilakukan diperoleh hasil sebagai berikut, pada variasi 1 dengan penambahan 0% plastik memperoleh nilai kuat tekan tertingi 29,82 MPa, variasi kedua dengan penambahan limbah plastik 2,5% memperoleh hasil kuat tekan tertinggi 25,86 Mpa sedangkan untuk variasi 7,5% penambahan limbah plastik memperoleh hasil tertinggi 20,94 Mpa. Hal ini menunjukan bahwa semakin besar penambahan limbah plastik maka semakin menurun nilai kualitas beton nya. Dalam penelitian ini beton tidak memenuhi syarat karena kuat tekan rata-rata diperoleh kurang dari kuat tekan rencana.

Abstract

The lack of utilization of ceramic shard waste at the moment is very little to be utilized, these ceramic shards cause more and more waste, causing soil pollution, because this waste cannot be decomposed. Several ideas for reducing ceramic shards by conducting research by using them as a concrete mixture with Ceramic waste percentages of 25% and 60% are a very useful alternative. amounting to 20.72 MPA. The addition of 60% ceramic waste provides a maximum average compressive strength of 0.96 MPA. THIS CONCLUSION IS DUE TO FACTORS, INCLUDING THEIR ADVERTISEMENT. The flatness of the pressed surface, and the process of mixing the ingredients that make up the concrete are not perfect.

Abstract

The law on construction services has been in effect for seventeen years, but the world of construction services in Indonesia has not been very exciting, especially for construction workers for large-scale and high-tech projects. Indonesia's workforce is still considered not to have capability comparable with foreign construction workforce.To realize the success of quality buildings and able to function as planned, needed human resources of good quality as well.And the professional ability of the construction workforce is evidenced by the possession of a skill or skill certificate. As mandated by the Construction Services Act No. 18 of 1999 article 9. that any individual employed by a business entity as a construction planner or supervisor of a particular construction or energy in a construction business enterprise shall have a certificate of expertise.Based on the research factors that most affect the application of Construction Services Act of 1999 memnai certificate of competence of experts on the implementation of construction work.is a factor of human resources such as education experts, experience, training, age and ownership of certificates. Another factor is the method of implementation of work such as coordination and decision making, while the political factor is the regulation of rules and leadership factors, such as motivation and awards To know how far and how big the role of these construction service experts in achieving the success of construction work, so much in demand by both local and foreign workers, it is deemed necessary to research the role of experts in contributing to the success of a construction work.Therefore it is necessary to develop further research on the readiness of experts in terms of the fulfillment of the requirements and expertise, in order to obtain the predicate of professional engineers or professional engineers through certification of expertise held by professional associations that followed.

Abstract

Given the last few years there have been many large earthquakes that have occurred in Indonesia. For example, the Aceh earthquake in 2004, the Yogyakarta earthquake in 2006, the Padang and Bengkulu earthquake in 2007. The earthquake caused a lot of damage to building structures. After conducting an in-depth study on this matter, that the large earthquake that occurred turned out to be due to the acceleration of the bedrock which was greater than the acceleration of the bedrock that had been determined in the SNI 03-1726-2012 earthquake map. Based on these findings, the earthquake map SNI 03-1726-2012 was deemed no longer suitable to be applied as a guideline for earthquake resistant structure planning. Because a new earthquake regulation appeared and was enforced, this resulted in the need for revision or review of existing buildings to be reviewed using the latest regulations. With the existence of the latest regulations (RSNI 03-1726-2019), all buildings planned with the old regulations (SNI 03-1726-2012) need an evaluation of the calculation of the earthquake effect of the old buildings against the latest regulations. Therefore, after conducting research by comparing the structural behavior between the two regulations in the USM psychology faculty lecture building in the T building by comparing SNI 03-1726-2012 with SNI 03-1726-2019, the comparison results obtained in the column of longitudinal reinforcement requirements experienced an increase of 50% and the need for shear reinforcement has increased by 12.04%, while for the comparison of beams the need for longitudinal reinforcement has increased in field reinforcement by 25%, and the shear reinforcement has increased by 25%
