Pertumbuhan jumlah kendaraan bermotor di Indonesia setiap tahunnya selalu meningkat. Konsekuensi dari pertumbuhan jumlah kendaraan bermotor tersebut adalah meningkatnya produksi ban kendaraan bermotor yang mengakibatkan menumpuknya limbah ban bekas. Salah satu inovasi untuk mengurangi limbah karet ban bekas adalah dengan memanfaatkannya dalam campuran aspal. Penelitian dilakukan untuk mengetahui perubahan indeks kekuatan sisa pada campuran Asphalt Concrete – Wearing Coarse (AC-WC), merupakan lapis perkerasan yang terletak paling atas yang berfungsi sebagai lapisan keausan dengan penambahan limbah karet ban bekas (crumb rubber) yang memenuhi Spesifikasi Bina Marga. Hasil penelitian menunjukkan bahwa penambahan limbah ban karet berpengaruh terhadap karakteristik marshall yaitu nilai berat jenis, berat jenis, Voids Filled With Asphalt (VFA), dan stabilitas tertinggi berada pada taraf 1%, sedangkan nilai Voids in Mix (VIM), Void in Mineral Agregate (VMA), dan flow tertinggi. berada pada level 9%. Dari uji index of retaining strength menunjukkan bahwa air berpengaruh terhadap keawetan campuran AC-WC, dibuktikan dengan nilai tertinggi pada lama perendaman selama 24 jam dengan konsentrasi 1% yang semakin menurun dengan bertambahnya lama waktu. dari perendaman. Penambahan limbah karet ban bekas (crumb rubber) ke dalam campuran AC-WC telah memenuhi Spesifikasi Bina Marga pada uji karakteristik Marshall, namun perubahan indeks kekuatan retensi hanya pada lama perendaman 24 jam, sedangkan untuk jangka waktu lain tidak sesuai dengan Spesifikasi Bina Marga. The growth of the number of motorized vehicles in Indonesia every year always increases. The consequence of the growth in the number of motorized vehicles is the increasing production of motorized vehicle tires which results in the accumulation of used tire waste. One of the innovations to reduce the waste of used tire rubber is to use it in asphalt mixtures. The study was conducted to determine the change in the index of retained strength in the Asphalt Concrete – Wearing Coarse (AC-WC), is the top layer of pavement which functions as the wear layer, mixture with the addition of waste rubber from used tires (crumb rubber) meeting the Bina Marga Specifications. The results showed that the addition of waste rubber tires affected the marshall characteristics, namely, the highest specific gravity, density, Voids Filled With Asphalt (VFA), and stability values were at a level of 1%, while the highest values of Voids in Mix (VIM), Void in Mineral Agregate (VMA), and flow were at a level of 9%. From the index of retained strength test, it shows that water affects the durability of the AC-WC mixture, as evidenced by the highest value at the duration of immersion for 24 hours with a concentration of 1%, which de-creases with increasing duration of immersion. The addition of used tire rubber waste (crumb rubber) to the AC-WC mixture has met the Bina Marga Specifications on the Marshall characteristics test, but the change in the index of retained strength was only for a 24-hour immersion duration, while for other durations were not according the Bina Marga Specifications.

“…Paving blocks or concrete bricks are building material products made from a mixture of water, aggregate and portland cement with additives that do not reduce quality (Standar Nasional Indonesia: Paving Block, 1996). Paving blocks are used as an alternative road surface covering such as sidewalks in cities, paving roads in housing complexes or residential areas, beautifying parks, yards and hardening parking areas, office areas, factories, parks and school yards (Fathurrahmaniah et al, 2022;Halim & Sepriyanna, 2022;Martina et al, 2019;Oktaviastuti & Leliana, 2020;Setiawan et al, 2021). Based on its classification, paving blocks have several qualities with their respective applications.…”

Candlenut is a superior commodity with great opportunities. Processing of candlenut seeds produces candlenut shells which are hard with a calorific value of 4164 cal/g so can be used as fuel. Processing candlenut shells as fuel produces waste of ash and not been utilized optimally. In this research, candlenut shell ash was used as a new alternative in making paving blocks, namely to substitute sand by 13%, 18% and 25% by weight of sand. The method used to analyze the chemical content of candlenut shell ash through XRF testing and compressive strength testing with a Compression Testing Machine after 28 days of curing time. Based on the results of the XRF test, hazelnut shell ash has a CaO content of 93.3%, where CaO is the main ingredient for making cement. In addition, the results of the average compressive strength of paving blocks at 13% substitution of candlenut shell ash produced a compressive strength of 5.89 Mpa, 18% substitution of candlenut shell ash of 8.72 Mpa, and 25% substitution of candlenut shell ash of 11.07 Mpa. The results of the compressive strength of paving blocks with the substitution of hazelnut shell ash produced standard standard paving block strength of D quality.
