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.

Sebagai bahan bangunan yang relatif masih baru, komposisi bahan penyusun bata non-bakar masih menjadi topik yang menarik untuk diteliti. Pada beberapa studi sebelumnya upaya mencari komposisi optimum campuran bata non bakar menggunakan metode eksperimen yang mengevaluasi pengaruh sebuah faktor dalam satu kali eksperimen atau yang dikenal dengan istilah single factor experiment. Kelemahan dari metode eksperimen ini adalah kesimpulan yang dihasilkan hanya terkait dengan satu faktor yang diamati itu saja. Sementara dalam kenyataannya, hasil dari sebuah proses tidak hanya dipengaruhi oleh satu faktor saja melainkan dipengaruhi oleh banyak faktor termasuk interaksinya. Studi ini dilakukan untuk mencari komposisi optimum bahan penyusun bata non bakar dengan menerapkan metode respon permukaan (Response Surface Method). Proses analisa data dilakukan dengan menggunakan software Minitab 17. Hasil penelitian menunjukan bahwa proporsi bahan yang menghasilkan kuat tekan paling optimal adalah semen (21,034%), pasir (28,9651%) dan tanah liat (50%), yang mampu menghasilkan bata non bakar dengan kuat tekan rata-rata sebesar 50.22 kg/cm2. Hasil penelitian ini juga merekomendasikan sebuah persamaan umum untuk memprediksi kuat tekan bata non bakar apabila menggunakan ketiga komposisi bahan tersebut, yaitu: y=-5,56x1+0,141x2+0,541x3+0,214x1 x2+0,0473x1 x_x-0,307x2 dengan x1, x2 dan x3 masing-masing adalah proporsi semen, pasir dan tanah liat.

When wood structures are exposed to high temperatures, they will decompose to provide a char layer and pyrolysis zone, an insulating material that inhibits further degradation. This experimental study aims to determine the char thickness and pyrolysis of solid wood exposed to fire for 30, 45, and 60 minutes. The post-fire shear strength has also been evaluated. The solid woods were locally from Nusa Tenggara Island, namely Jati Putih, Bajur, and Rajumas. According to the Indonesian National Standard of the heating curve for structures, the temperature growth was SNI-1741: 2008. Obtained The char layer's highest average thickness was within 60 minutes of combustion with the highest temperature of 1055oC. The char layer for Jati Putih, Bajur, and Rajumas are 2.12 mm, 7.89 mm, and 6.53 mm. Meanwhile, the pyrolysis layers are 8.78 mm, 9.13 mm, and 14.82 mm, respectively, for Jati Putih, Bajur, and Rajumas. Besides, the post-fire shear strength of all wood species shows an increase in shear strength in the core. Wood can still sustain the load during a fire because there is a char layer preventing the core section from immediately exposed to the fire.

Land acquisition for strategic infrastructure is conducted through the release of land rights with fair compensation in accordance with Law Number 2 of 2012. The Interconnection Pipeline Network Project of IPA Sepaku Semoi to IPA Sepaku encountered land acquisition challenges that delayed construction progress. The method employed systematic coordination of administrative and technical verification involving LMAN, BPN, and OIKN. Based on direct observation during the internship period from 8 January to 28 February 2026, the results indicate that although 7,040 meters of pipeline route were ready in December 2025, the length increased to 8,214 meters by February 2026 following document verification and compensation payments. Through intensive socialization and a dialogic approach, community acceptance improved significantly. This ensured smooth land release, a reliable clean water supply for local residents, and positive economic contributions to the Ibu Kota Nusantara development area.

The ever-evolving construction industry demands innovation in high-quality, economical, and efficient concrete materials. Self-Compacting Concrete (SCC) is one solution due to its self-compacting ability. However, extreme conditions often affect the setting and hardening time of concrete, requiring the use of additives in the form of accelerators to accelerate or retarders to slow down the setting time. This study aims to analyze and compare the compressive strength values of SCC concrete using accelerator and retarder additives through a destructive test method. This study was conducted at the Civil Engineering Laboratory of the University of Muhammadiyah Mataram. The test specimens used were concrete cylinders measuring 15 cm x 30 cm with a design compressive strength of f’c = 20 MPa and an additive dosage of 0.5%. Fresh concrete characteristics testing included slump flow, J-ring, and sieved stability index. The compressive strength testing of hardened concrete was carried out using a Compression Testing Machine (CTM) at the ages of 7, 14, 21, and 28 days. The test results showed that the material and fresh concrete had met all the eligibility criteria for SCC concrete, with a slump flow distribution value of 65 cm, J-ring 67 cm, and a sieve stability index of 17.52%. The use of accelerator additives proved to be the most effective in increasing early strength and producing the highest compressive strength of 24,84 MPa on the 28th day. The use of retarder produced a compressive strength below normal concrete at the age of 7 days (14.60 MPa compared to 15.56 MPa), but showed a better increase in strength at the age of 28 days. Overall, the choice of additive type must be adjusted to the needs, accelerator is effective in accelerating hardening, while retarder is more suitable for improving long-term workability.

Ring of Fire and at the intersection of three tectonic plates. Efforts are needed to minimize earthquake damage, one of which is the use of a base isolator system. This study aims to determine the effect of using High Damping Rubber Bearing (HDRB) with a diameter of 800 mm on the behavior of reinforced concrete structures in tall buildings under seismic loads. The research location is the 7-story Sapadia Hotel building in the city of Mataram. The research is conducted by analyzing a 3D model of the fixed base structure and the base isolator structure using numerical analysis. The results show an increase in the base displacement of the base isolator structure by 59% in the x-direction and 44% in the y-direction, while the inter-story displacement decreases by 36% in the x-direction and 69% in the y-direction. The use of base isolators can reduce the shear force by 35% in the x-direction and 15% in the y-direction. Based on the pushover analysis, the roof displacement values for the fixed base and base isolator structures are 0.159 m and 0.129 m respectively. These values can be used to determine the structural performance level according to ATC-40. The maximum drift value for the fixed base structure is 0.0055 m. For the base isolator structure, the maximum drift value is 0.0044 m, categorized as Immediate Occupancy (IO). This value can be used to determine the performance level of the structure based on ATC-40. The maximum drift value of the fixed base structure is 0.0055m. While in the base isolator structure, the maximum drift value is 0.0044 m which is included in Immediate Occupancy (IO). Thus, the use of base isolators in high-level buildings is able to reduce post-earthquake damage and the building is still safe to continue using.
