AbstrakPada campuran perkerasan aspal dibutuhkan bahan pengisi (filler) untuk mendukung kinerja konstruksi perkerasan jalan agar dapat menahan beban lalu lintas. Berbagai jenis filler telah banyak digunakan antara lain abu batu, semen portland dan lain-lain. Namun keterbatasan sumber daya alam mendorong upaya pemanfaatan bahan-bahan buangan dalam konstruksi perkerasan jalan. Pada penelitian ini, digunakan limbah kaca sebagai filler pada campuran perkerasan aspal. Penelitian ini bertujuan untuk mengetahui prosentase filler limbah kaca yang paling optimum dan pengaruhnya terhadap kinerja campuran. Kinerja tersebut diukur melalui pengujian stabilitas, flow, Marshall Quotient, rongga dalam campuran, rongga di antara mineral agregat, rongga terisi aspal, Marshall immersion, tegangan tarik tidak langsung dan Cantabro loss. Hasil penelitian menunjukkan bahwa penggunaan limbah kaca dengan proporsi 75% terhadap berat filler meningkatkan stabilitas dan kekakuan campuran sehingga lebih mampu untuk menerima pembebanan. Campuran dengan proporsi 75% filler limbah kaca menghasilkan nilai VIM dan VMA lebih kecil serta nilai VFB lebih besar yang mengindikasikan bahwa campuran memiliki daya ikat dan sifat saling mengunci yang kuat sehingga menghasilkan rongga lebih kecil serta selimut aspal lebih tebal. Berdasarkan hasil uji Marshall immersion dan Cantabro loss, campuran dengan proporsi tersebut lebih tahan terhadap rendaman air sehingga memiliki durabilitas lebih tinggi serta lebih tahan terhadap potensi disintegrasi. AbstractFiller is required in the asphalt concrete mixture to support the performance of pavement construction in order to withstand the traffic load. Various types of filler has been widely used, such as stone ash, portland cement and others. However, because of limitation of available natural resources, there has been a significant increase in the demand for using waste materials in pavement construction. In this study, waste glass was used as filler in asphalt concrete mixture. This study aims to determine the optimum percentage of waste glass filler and evaluate its effect on the performance of asphalt concrete mixtures. The performance was measured in term of stability, flow, Marshall Quotient, voids in mix, voids in the mineral aggregate, voids filled with bitumen, Marshall immersion, indirect tensile strength and Cantabro loss. The results showed that using the percentage of waste glass of 75% by weight of filler increased stability and stiffness so that the mixture became stronger to withstand the load. The mixtures with a proportion of 75% waste glass filler have smaller VIM and VMA values and a larger VFB. It is indicated that the mixtures have strong bonding and interlocking properties resulting in smaller voids and thicker asphalt binder film thickness. Based on the results test of Marshall immersion and Cantabro loss, the mixtures with stated proportion more resistant to water immersion, resulting in higher durability and greater resistance to potency of disintegration.

Asphalt modification by adding fiber powder of banana stem can be implemented to improve the performance of pure asphalt. Asphalt concrete binder course AC-BC is a flexible pavement layer that functions to distribute the load towards the foundation layer. So it really needs strength, durability and stability of the materials. For that, it is necessary to use asphalt modification with fiber powder of banana stem which is used as a binding material in AC-BC asphalt concrete mixture. The proper percentage of modified asphalt level will determine the optimum quality of an asphalt mixture. Asphalt concrete specimens were made in 3 (three) samples for each variation of asphalt level by 5%; 5.5%; 6%; 6.5%; and 7%. The asphalt optimum level in the mixture is carried out through volumetric investigation in the form of VMA, VIM, and VFB values and mechanical assessment in the form of stability, flow and Marshall Quetient. The results of data analysis found that the value of VIM, stability and MQ tend to decrease with increasing levels of modified asphalt. On the other hand the value of VMA, VFB and flow tend to rise with increasing levels of modified asphalt. However, from the five variations of asphalt levels obtained asphalt levels of 5% and 5.5% which meet all the specifications of AC-BC asphalt concrete specification. To determine the asphalt optimum level, the average of qualified asphalt level is taken. So that the asphalt concrete AC-BC will produce a better structural performance at 5.25% asphalt level with banana stem fiber powder on asphalt by 0.1%.

The performance of road pavement is strongly determined by material used in asphalt mixture. However, it is occasionally found that asphalt used in hot mix asphalt did not fulfill softening point requirement. On the other hand, the amounts of waste styrofoam and PVC are tend to increase and need a large space for its handling. Therefore, it is necessary to improve the quality of asphalt by using waste styrofoam and PVC. This article aims to review the performance of asphalt concrete using waste styrofoam and PVC as asphalt modifier based on the value of its penetration index. Styrofoam modified asphat was made by mixing asphalt penetration grade 60/70 with 0%, 2%, 4% and 6% waste styrofoam, meanwhile the percentages of waste PVC as asphalt modifier were 1%, 2%, 3% and 4%, respectively. The properties analyzed are Marshall stabiliy, flow, Marshall Quotient, Marshall immersion and retained strength index. From the analysis, it can be concluded that the use of waste styrofoam and PVC increase modified asphalt penetration index, and its penetration index significantly affect the properties of asphalt concrete

The "Sapu sae" waste cooperative is a joint effort of community groups in Jelantik Village to collect waste, especially plastic waste, to overcome the problem of plastic waste while improving the welfare of the residents. However, this cooperative is currently no longer operating due to various reasons. Difficulty in collecting waste due to residents' refusal, lack of administrative and financial management capabilities and unclear management of the cooperative are the main reasons why this cooperative is unable to survive. This activity aims to revive village waste management activities. This service activity uses a solution approach method for cooperative problems. The activities are carried out in several stages, including the revitalization of cooperatives, simple bookkeeping and finance training for administrators, waste management training for members, providing minimal assistance for cooperatives and closing with mentoring and evaluation. This activity has been carried out and received a warm welcome from the Jelantik Village community. The waste cooperative has been revived with new legal administrators who have been given bookkeeping training. Cooperative members were also given training in making handicrafts made from waste. Service activities also provide minimal means for carrying out cooperative activities in the form of garbage collection sacks, member savings books and cooperative administration book packages. This activity has been evaluated and shows positive developments with the return of the cooperative and increasing public awareness in waste management.

Untuk meningkatkan keawetan lapis perkerasan jalan, dikembangkan aspal modifikasi polimer antara lain dengan limbah styrofoam dan limbah PVC yang memiliki nilai viskositas lebih tinggi dari aspal konvensional. Keawetan perkerasan jalan sangat ditentukan oleh sifat volumetrik campuran yang merupakan persyaratan agar lapis perkerasan jalan dapat berfungsi sesuai dengan umur yang telah direncanakan. Tulisan ini bertujuan untuk mengkaji hubungan antara viskositas aspal modifikasi limbah styrofoam dan limbah PVC dengan sifat volumetrik campuran laston. Sifat volumetrik campuran laston yang dikaji adalah rongga di antara mineral agregat (VMA), rongga dalam campuran (VIM), rongga terselimuti aspal (VFB) dan berat jenis (bulk specific gravity). Untuk membuat aspal modifikasi, aspal penetrasi 60/70 dicampur dengan limbah styrofoam sebesar 0%, 2%, 4% dan 6% sedangkan limbah PVC digunakan sebesar 1%, 2%, 3% dan 4% terhadap berat aspal modifikasi tersebut. Berdasarkan analisa yang dilakukan disimpulkan bahwa penggunaan limbah styrofoam dan limbah PVC meningkatkan nilai viskositas aspal modifikasi. Peningkatan viskositas aspal modifikasi limbah styrofoam dan limbah PVC memperbesar nilai VMA dan VIM serta memperkecil nilai VFB dan berat jenis (bulk specific gravity). Secara umum viskositas aspal modifikasi limbah styrofoam dan limbah PVC berpengaruh sangat signifikan terhadap sifat volumetrik campuran laston.

Pada konstruksi perkerasan jalan, agregat mempunyai proporsi yang sangat besar yaitu sekitar 90% terhadap berat campuran beraspal. Agregat harus memenuhi kriteria sesuai dengan persyaratan yang telah ditentukan karena kinerja konstruksi perkerasan jalan sangat tergantung dari karakteristik agregat yang digunakan. Tujuan dari tulisan ini adalah untuk menelaah hubungan antara karakteristik agregat terhadap nilai indirect tensile strength pada lapis aspal beton (laston). Agregat kasar yang digunakan dibedakan berdasarkan nilai aggregate impact value (AIV) serta variasi proporsi bentuk kubus dan pipih. Kajian karakteristik agregat tersebut meliputi berat jenis bulk, berat jenis kering permukaan jenuh, berat jenis semu, berat jenis efektif, penyerapan air dan tingkat kekerasan agregat. Berdasarkan analisa yang dilakukan dapat disimpulkan bahwa peningkatan nilai berat jenis bulk, berat jenis kering permukaan jenuh, berat jenisÂ semu dan berat jenis efektif berdampak pada peningkatan nilai indirect tensile strength. Pada penyerapan air dengan rentang 1.80-3.11%, kemampuan campuran untuk menahan beban tarik semakin rendah seiring dengan semakin besarnya penyerapan air tersebut. Pada seluruh jenis dan komposisi agregat yang diujikan, semakin rendah tingkat keausan agregat menghasilkan nilai indirect tensile strength yang semakin tinggi. Secara umum karakteristik agregat berpengaruh kuat terhadap nilai indirect tensile strength.

Agregat yang digunakan sebagai bahan perkerasan jalan harus memenuhi persyaratan tertentu agar dapat memikul beban lalu lintas selama umur yang telah direncanakan. Salah satu karakteristik agregat yang menentukan mutu campuran perkerasan adalah gradasi atau distribusi ukuran partikel agregat tersebut. Gradasi yang digunakan dalam campuran perkerasan merujuk pada spesifikasi yang telah ditetapkan Direktorat Jenderal Bina Marga. Tulisan ini ingin mengkaji perbedaan gradasi agregat dan pengaruhnya terhadap sifat-sifat volumetrik campuran. Berdasarkan distribusi ukuran partikel agregat, dianalisa hubungan antara ketebalan selimut aspal dengan sifat-sifat volumetrik yaitu rongga dalam campuran (VIM), rongga di antara mineral agregat (VMA), rongga terselimuti aspal (VFB) dan tingkat kepadatan (density). Dari analisa yang dilakukan, disimpulkan bahwa distribusi ukuran partikel agregat sangat menentukan luas permukaan agregat yang diselimuti aspal. Gradasi agregat yang lebih kasar menghasilkan nilai VMA dan VFB yang lebih kecil dan nilai VIM yang lebih besar. Kepadatan campuran mengalami peningkatan dengan bertambahnya ketebalan selimut aspal. Pada semua parameter yang dianalisa, distribusi ukuran partikel agregat berpengaruh secara signifikan.
