Abstract

The characteristics of semi-flexible pavement (SFP) are strongly influenced by the proportion of cement mortar content filling the voids in the mixture. SFP behavior due to repeated traffic loads causes the pavement structure to experience stress and strain around the wheel axis, resulting in a rapid decline in performance with cracks and permanent defects. Evaluation of the properties of the mixture on the stress-strain parameters of the influence of additives and substitution of many SFP mixture-forming materials has been carried out. The purpose of this study was to determine the stress-strain models of SFP with the effect of waste tire rubber (WTR) additives in asphalt and Aceh natural zeolite substitution in cement mortar under uniaxial compressive load. The porous asphalt mixture is designed in accordance with the optimum asphalt content and open graded aggregate based on the specifications of Bina Marga Regulation 2010 and Australian Asphalt Pavement (AAPA) 2004. The composition of zeolite in SFP mixture can affect the stress behavior, where zeolite can inprove quality of the mortar cement so that it can slow down the development of the SFP mixture flatness and the maximum stress obtained is 17 MPa at 5% zeolite composition. The bilinear model of stress-strains was proposed the results show a good agreement with experimental results.

Abstract

Sukarara Village is known as one of the centers of pottery craftsmanship, renowned for its high artistic and cultural value. However, most pottery entrepreneurs in the village still rely on conventional marketing methods, which limits their market reach and is less effective in today's digital era. This community service activity aims to assist these entrepreneurs in developing marketing strategies through the introduction and use of social media as a means of promotion and market expansion. The methods used include outreach, hands-on training, and intensive mentoring on platforms such as Instagram, Facebook, and WhatsApp Business. The activities also cover the creation of engaging promotional content, social media account management, and a basic understanding of digital market analysis. The results show an increase in participants' understanding and skills in using social media to support product marketing. Several entrepreneurs have begun to independently create and manage their business social media accounts, as well as enhance online interaction with consumers. Another positive impact observed is the growing motivation among entrepreneurs to innovate and adapt to technological developments. This activity proves that social media-based marketing strategies are highly relevant and effective in driving the growth of local MSMEs, particularly in the handicraft sector. Going forward, continued mentoring is expected to ensure sustainability and optimal business development.

Abstract

Abstrak Ketahanan struktur perkerasan akibat timbulnya tegangan dan regangan menyebabkan retak awal saat terjadinya deformasi permanent sehingga kegagalan perkerasan akibat kelelahan umur tidak dihindarkan. Fenomena tersebut dapat dikurangi dengan perkerasan yang memiliki cukup kekakuan, kelenturan. Modifikasi material dilakukan untuk meningkatkan nilai kekakuan dan kelenturan campuran dengan menggunakan jenis campuran,gradasi, dan modifikasi aspal yang tepat sebagai usaha pengembangan campuran perkerasan beraspal. Tujuan dari penelitian ini  mempelajari tegangan dan regangan tarik campuran PSF  terhadap beban berulang dengan tambahan WTR dan menggunakan ziolit alam sebagai pengganti sebagian semen untuk mortar yang dinjeksi ke dalam rongga aspal porous. Desain campuran aspal berpori dimulai dengan penentuan proporsi aspal optimal dengan agregat bergradasi terbuka sebagaimana ditentukan dalam sepesifikasi (AAPA) 2004. Uji Marshall dilakukan untuk mengetahui spesifikasi yang disyaratkan dan dilanjutkan dengan uji specimen yang telah diinjeksi mortar semen dengan pengujian lentur metode pembebanan empat titik untuk evaluasi tegangan dan regangan tarik. Nilai tegangan dan regangan dinamis dianalisis pada setiap variasi ziolit dalam mortar semen. Substitusi ziolit alam pada semen mortar dapat mempengaruhi tegangan dan regangan dinamis campuran PSF, di mana semakin besar komposisi ziolit dalam semen mortar nilai tegangan dan regangan yang dihasilkan semakin tinggi. Kata kunci: perkerasan semi-fleksibel, ziolit alam, reologi aspal, tegangan dan regangan, beban dinamis  Abstract The resistance of the pavement structure due to the consequence of stress and strain causes the initial reset when the occurrence of permanent deformation so that pavement failure due to age is avoided. This phenomenon can be reduced by a pavement that has sufficient stiffness and flexibility. Material modification is carried out to increase the value of the stiffness and flexibility of the mixture by using the right type of mixture, gradation, and asphalt modification as an effort to develop an asphalt pavement mixture. The purpose of this study was to study the stress and tensile strain of the semi-flexible pavement (SFP) mixture against repeated loads with the addition of rubber tire waste (WTR) and to use natural zeolite as a part of cement for mortar injected into the porous asphalt cavity. The design of a porous asphalt mixture begins with the determination of the optimal proportion of asphalt with an open grade aggregate specified in the Asphalt Pavement Association Australia (AAPA) 2004.Marshall test is carried out to see the required specifications and test specimens that have been injected with cement with a four-point loading bending method test for stress evaluation and tensile strain. The values of dynamic stress and strain were analyzed for each variation of ziolite in cement mortar. Substitution of natural ziolite in cement mortar can affect the dynamic stress and strain of the PSF mixture, where the greater the ziolite composition in cement mortar, the higher the resulting stress and strain. Keywords: Pavement semi-flexible, natural zeolite, asphalt rheology, dynamic stress and strain
