The continuous development of artificial aggregates aims to address the limitations of natural aggregates. The increase in ceramic waste can have a negative impact on the environment. It is hoped that research using ceramic waste as an alternative aggregate can overcome the limitations of natural aggregates while reducing environmental pollution. This research focuses on assessing the volumetric and mechanical characteristics of Laston AC-BC mixtures, replacing natural fine aggregate with ceramic waste. Additionally, to determine the percentage of ceramic fine aggregates that meets the performance of the laston AC-BC mixture. Utilizing ceramic waste, 60/70 pen asphalt with 6% KAO, coarse aggregate, fine aggregate, and fly ash, the ceramic pieces are processed to meet standard particle sizes. The laston AC-BC mixture was designed with varying ceramic fine aggregate proportions of 0%, 25%, 50%, 75%, and 100%. Results indicate that ceramic fine aggregate effectively replaces natural fine aggregate up to a maximum of 55.45%, impacting VMA and VIM positively. Conversely, the voids filled with asphalt decrease as the percentage of ceramic fine aggregates used increases. The VIM value still meets Bina Marga requirements up to 55.45% use and the VFB value up to 60.6% ceramic fine aggregate. The Laston AC-BC mixture using fine ceramic aggregate can reduce the stability and flow value, although it still meets Bina Marga requirements but potentially reducing load-bearing capacity. ABSTRAK Pembuatan agregat buatan ataupun memanfaatkan bahan lain sebagai pengganti atau substitusi agregat alam terus berkembang untuk pemenuhan kebutuhan agregat atas keterbatasan sumber daya alam. Limbah keramik selama ini hanya dimanfaatkan sebagai timbunan, jika dibiarkan dan tidak dimanfaatkan kembali akan berakibat mengotori lingkungan. Pemanfaatan limbah keramik sebagai agregat alternatif diharapkan dapat mengatasi masalah tersebut. Penelitian ini bertujuan untuk mengetahui karakteristik volumetrik dan mekanis campuran laston AC-BC dengan mengganti agregat halus alam dengan agregat halus keramik. Selain itu juga untuk mengetahui prosentase limbah keramik sebagai agregat halus yang memenuhi kinerja campuran beraspal AC-BC. Bahan terdiri dari limbah keramik, aspal pen 60/70 dengan KAO 6%, agregat (kasar, halus dan filler abu batu). Potongan keramik terlebih dahulu dipecahkan dan dihaluskan hingga memenuhi standar diameter butir agregat halus. Campuran laston AC-BC dirancang menggunakan lima variasi agregat halus keramik yaitu 0, 25, 50,75 dan 100%. Hasil analisis diperoleh bahwa agregat halus keramik bisa menggantikan agregat halus alam sampai prosentase maksimum 55,45%. Semakin banyak agregat halus keramik yang digunakan dapat meningkatkan rongga antar agregat dan rongga dalam campuran laston AC-BC. Sebaliknya rongga yang terisi oleh aspal mengalami penurunan seiring meningkatnya prosentase agregat halus keramik yang dipakai. Nilai VIM yang masih memenuhi persyaratan Bina Marga sampai penggunaan 55,45% dan nilai VFB sampai 60,6% agregat halus keramik. Selain itu Campuran laston AC-BC yang menggunakan agregat halus keramik dapat menurunkan nilai stabilitas dan flow campuran, walaupun masih memenuhi persyaratan Bina Marga tapi nilai tersebut cenderung membuat kemampuan campuran menahan beban semakin rendah berkurang.

Tahap perkembangan remaja pada siswa SMA/SMK membawa pengaruh pada pengelolaan emosi yang berdampak terhadap perilaku berlalu lintas. Untuk meningkatkan kesadaran serta mengurangi resiko kecelakaan berlalu lintas pada usia remaja, diperlukan pendidikan keselamatan berlalu lintas berupa kegiatan sosialisasi keselamatan berlalu lintas. Kegiatan sosialisasi dilaksanakan di SMKN 1 Mataram dengan kondisi lalu lintasnya yang cukup padat. Kegiatan sosialisasi diawali dengan pretest untuk mengetahui tingkat pengetahuan siswa terhadap keselamatan berlalu lintas. Kemudian pemaparan materi yang disampaikan oleh Ditlantas Kepolisian Daerah Nusa Tenggara Barat, Dinas Perhubungan Provinsi Nusa Tenggara Barat dan dosen/civitas akademik Jurusan Teknik Sipil Fakultas Teknik Universitas Mataram. Setelah itu, dilanjutkan dengan sesi tanya jawab dan kuis untuk menguji serta memperdalam pengetahuan siswa terhadap topik yang disampaikan dengan cara yang interaktif. Kegiatan sosialisasi ditutup dengan penyerahan simbolis alat keselamatan jalan kepada Kepala SMKN 1 Mataram untuk demontrasi nyata penggunaan alat keselamatan jalan di lingkungan SMKN 1 Mataram. Hasil kegiatan ini menunjukkan bahwa para siswa telah mendapatkan pemahaman mengenai keselamatan berlalu lintas di jalan.

Sustainable Development Goals (SDGs) in protecting marine and coastal ecosystems and reducing the risk of natural disasters can be achieved through mangrove planting activities at Cemara Beach. Mangroves are useful in maintaining ecosystem balance, protecting the coastline from abrasion and absorbing carbon dioxide which can reduce the impact of climate change. Mangrove planting activities involve local communities in the planting and maintenance process, and contribute to improving community welfare and environmentally-based economic development. Mangrove planting activities use seedlings aged 3 to 6 months. Mangrove planting is in a location with a water depth of 10 to 50 cm. The size of the mangrove seedlings planted is 15 to 30 cm. The type of mangrove planted at Cemara Beach is Rhizophora. Mangrove planting activities support SDGs 13, 14, dan 15 tentang climate action, life below water, and life on land.

In tropical countries such as Indonesia, high-temperature resistance of asphalt is required to avoid premature damage to road pavement construction. One of the methods to solve this problem is to prepare polymer-modified asphalt. This study aimed to examine the temperature change sensitivity of polymer-modified asphalt using the penetration index value. The polymers used were HDPE, LLDPE, PVC, and styrofoam. Based on the analysis, it was concluded that the conventional asphalt 60/70 used in this study did not satisfy the minimum softening point requirement of 48 °C. With the use of polymers, modified asphalt is produced with a higher hardness than unmodified asphalt. Compared to other polymers, LLDPE-modified asphalt has the lowest penetration index value and is the most sensitive to temperature changes, making it more susceptible to permanent deformation. At all the styrofoam concentrations used, the penetration index was negative, while a positive penetration index value was achieved with 3% and 4% PVC. In HDPE-modified asphalt, the use of polymers has a significant impact and produces the highest penetration index. This indicates that HDPE-modified asphalt is more resistant to temperature changes and exhibits better performance under various weather conditions In tropical countries such as Indonesia, high-temperature resistance of asphalt is required to avoid premature damage to road pavement construction.

Labanasem, Kabat, Banyuwangi Regency consists of 5 hamlets, namely West Krajan, East Krajan, Sukadi, Gotan, and Kawang. The majority of people in Labanasem work as farmers because they have a fairly large agricultural land sector. One of the problems experienced by craftsmen is that most craftsmen have not calculated and analyzed the feasibility of the products they produce. In addition, the group has not been touched by technology and advanced green economy material innovation, therefore with the problem of production costs, it is necessary to optimize production costs with environmentally friendly raw materials and develop more economical product innovations made from rice straw waste that can increase the added economic value of partners. Based on problems, the purpose of community service activities is to empower the Building Materials Craftsmen Group in utilizing rice straw waste for Interlock Concrete Straw Blocks material innovation in Labanasem, Banyuwangi and to analyze the feasibility of interlock concrete straw block material (BERATON). Based on the analysis results, it can be seen that the BERATON product was an innovative and profitable product, the profits obtained by partners in 2024 can reach Rp 39,229,720.00, in 2025 it reaches Rp 48,623,250.00 and in 2026 it reaches Rp 46,982,250.00. The R/C Ratio value was 4.6; the B/C ratio value was 3.6 and the IRR value was 89.34%
