Abstract

The stability of the soil structure is something that needs to be considered in development. Increasing soil structure improvement can be done through various efforts using added materials or compaction processes. This study aims to improve the clay soil on the kerot kediri road using paper waste. The research was conducted experimentally by making samples in the laboratory. The land used is from the Totok Kerot road, Kediri, which has damaged the road surface due to land loans. Waste paper was added at 0% 7.5%, 10%, 15%, and 20% of the weight of the test object. Waste paper is used with pulp after it is dried and pulverized to a certain gradation. The tests carried out include the Consistency Limit (Atterberg Limit) and Soil Compaction (Proctor) tests. The results showed that the addition of waste paper affects the original properties of the soil. The addition of paper moisture content decreases the Plastic Index value and increases the dry volume of the soil. The addition of waste paper content also increases the volume of dry soil water but decreases after reaching the optimum point, namely at 10% paper waste content and 9.96% water content with a dry volume weight value of 1.97gr/cm3. The greater the dry volume of soil, the dry density indicates that the soil is getting higher. So that by knowing these results, it can be used as a reference in the process of repairing and backfilling the soil on the Totok Kerot Kediri road.

Abstract

Concrete is a vital component of construction. One of them is lightweight concrete consisting of a mixture of coarse aggregate, fine aggregate, cement which is united by water in a predetermined ratio. Lightweight concrete is concrete which has a weight of less than 2000kg / m³, lightweight concrete usually uses aggregate or lightweight material so that the concrete produced also has a light specific gravity. Waste cigarette filler waste is a waste that is difficult to recycle. Cotton filter cigarette butts are cotton-based fibers that are lightweight, porous and easily absorb water. For the use of this waste as a substitute for overall coarse aggregate, research needs to be carried out, namely the amount of compressive strength produced by replacing coarse aggregate from cigarette butts waste, job mix used according to SNI K-125 by completely replacing coarse aggregate with cigarette butts waste, Job mix for 1m³ concrete consists of 276 kg of cement, 214 liters of water, 148.62 kg of cigarette butts, and 828 kg of sand. From the above research, the highest compressive strength at 28 days reached K-115.56, which means that the target for concrete paving has reached K-100. As for the absorption, value is quite high from consecutive tests for ¼ hours, 1 hour, 4 hours, and 24 hours produced an average value of 0.116 liters, 0.269 liters, 0.374 liters, 0.699 liters. The results of the study of concrete density with a coarse aggregate of cigarette butts waste reached an average of 1831.11 kg / m³, for the study the pore figures yielded an average value of 0.2854, then the results of the porosity values obtained an average of 0.222016.                                                 AbstrakBeton merupakan komponen vital pada suatu konstruksi. Salah satunya beton ringan yang terdiri dari campuran agregat kasar, agregat halus, semen yang dipersatukan oleh air dengan perbandingan yang telah ditentukan. Beton ringan adalah beton yang memiliki berat kurang dari 2000kg/m³, beton ringan biasanya menggunakan agregat atau bahan yang ringan sehingga beton yang di hasilkan juga memiliki berat jenis yang ringan. Limbah puntung rokok fillter adalah suatu limbah yang sulit untuk di daur ulang. Puntung rokok fillter berbahan dasar kapas yang merupakan serat yang memiliki sifat ringan, berpori, dan mudah menyerap air. Untuk penggunaan limbah ini sebagai pengganti agregat kasar secara menyeluruh perlu diadakan  penelitian yaitu besarnya kuat tekan yang di hasilkan dengan penggantian agregat kasar dari limbah puntung rokok tersebut, job mix yang digunakan sesuai SNI K-125 dengan mengganti sepenuhnya agregat kasar dengan limbah puntung rokok,,job mix untuk 1m³ beton terdiri dari semen 276 Kg, air 214 liter, puntung rokok 148,62 Kg, dan pasir sebanyak 828 Kg. Dari penelitian di atas diperoleh nilai kuat tekan pada umur beton 28 hari tertinggi mencapai K-115,56 yang berarti telah mencapai target untuk paving beton sebesar  K-100.

Hasil penelitian dari berat jenis beton dengan agregat kasar limbah puntung rokok mencapai rata-rata 1831,11 Kg/m³, untuk penelitian angka pori di hasilkan nilai rata-rata mencapai 0,2854, selanjutnya hasil nilai porositas diperoleh rata-rata mencapai 0,222016.
