One method for enhancing the natural state of the soil is soil stabilization. Spent bleaching earth (SBE) is the solid waste left over after palm oil is refined for use in oleochemical industry processes. When the field test value exceeds 3% and the laboratory test value exceeds 6%, the soil strength is deemed favorable. The test results indicate that as the curing time increased, the natural soil's California Bearing Ratio (CBR) value increased as well. After 0 days of curing, the natural soil's CBR value was 11.91%; after 4 days, it rose to 12.59%; and after 7 days, it reached 13.99%. Furthermore, the soil that underwent a 4-day soak had a CBR value of 4.01%. Concurrently, the CBR value increased with increasing curing time in the mixed soil CBR test, which had a composition of 10% cement and 22.5% SBE. The mixed soil's CBR value at 0 days of curing was 12.66%. Nevertheless, the CBR value increased significantly to 22.64% after 4 days of curing. Furthermore, the CBR value increased to 27.11% after 7 days of curing. The mixed soil's CBR value was 23.52% over the course of the four-day soaking period. We can conclude that the natural soil and the mixed soil exhibit their highest CBR values following a 7-day curing period. This suggests that the CBR value is influenced by the curing time. In both soil types, a higher CBR value was noted with longer curing times.

[IN] Gedung Kuliah Terpadu (GKT) 1 Politeknik Negeri Bengkalis direncanakan 3 lantai dengan bentuk asimetris dan berfungsi sebagai gedung administrasi dan laboratorium, dengan kondisi wilayah Bengkalis yang berpotensi gempa sangat kecil. Berdasarkan hal tersebut, pada GKT 1 dilakukan evaluasi pada struktur kolom dengan asumsi bahwa di daerah Bengkalis terjadi peningkatan percepatan tanah puncak atau (Peak Ground Acceleration, PGA) menurut SNI 1726-2019. Tujuan penelitian ini untuk mengetahui apakah keandalan struktur kolom yang direncanakan stabil dari pengaruh nilai tekuk dalam menahan beban aksial maksimum yang bekerja, akibat peningkatan percepatan tanah puncak atau (Peak Ground Acceleration, PGA). Metode yang digunakan adalah metode probabilitas distribusi normal (Gaussian), yang dapat menentukan keandalan struktur kolom dalam menahan beban kerja maksimum akibat peningkatan percepatan tanah puncak atau (Peak Ground Acceleration, PGA) yang dilakukan pada GKT 1. Dengan struktur kolom yang ditinjau yaitu C27, yang merupakan kolom kritis dengan beban aksial paling maksimum (Pmaks) yang diterima. Hasil evaluasi pada kolom kritis C27, beban aksial maksimum 109,044 ton menghasilkan nilai tekuk sebesar 95,0488 mˉ² dengan keandalan 99,8% berdasarkan kondisi eksisting dilapangan, sedangkan untuk beban aksial maksimum 155,040 ton setelah diasumsikan terjadinya percepatan tanah puncak (Peak Ground Acceleration, PGA) berdasarkan SNI 1726-2019 menghasilkan nilai tekuk 97,5715 mˉ² dengan keandalan sebesar 91,9 %. [EN] Gedung Kuliah Terpadu (GKT) 1 Politeknik Negeri Bengkalis is designed as a three-story building with an asymmetrical shape, functioning as an administrative and laboratory facility. Considering that Bengkalis is located in an area with very low earthquake potential, an evaluation was conducted on the column structure by assuming an increase in Peak Ground Acceleration (PGA) based on SNI 1726-2019. This study aims to determine whether the reliability of the designed column structure remains stable in resisting maximum axial loads when subjected to increased soil acceleration. The method applied in this research is the normal distribution probability (Gaussian) method, which is used to assess the reliability of the column structure in withstanding maximum loads resulting from the assumed increase in PGA. The structural analysis focuses on column C27, identified as the critical column due to receiving the highest axial load (Pmax). The evaluation results show that for column C27, the maximum axial load of 109.044 tons produces a bending value of 95.0488 mˉ² with a reliability of 99.8% under existing field conditions. However, when the maximum axial load increases to 155.040 tons—based on the assumed peak ground acceleration according to SNI 1726-2019—the bending value rises to 97.5715 mˉ², and the reliability decreases to 91.9%. These findings indicate that an increase in PGA significantly affects the reliability of the column structure, although it remains within the safe category.

The background to the research that will be carried out is that the large amount of standing water on the road pavement in each rainy season results in disturbances to motorists' comfort. This is due to impermeable road pavement and poor drainage along the road. Porous asphalt can increase rainwater absorption, thereby reducing puddles on the road surface. Porous asphalt is a new breakthrough in the world of road pavement to reduce the appearance of puddles of water when it rains. Porous asphalt is also designed to have high porosity so that water can flow through side channels and a waterproof base layer to prevent water from seeping into the subbase layer and road body so as to minimize puddles of water on the road surface which often occur after rain and disrupt the smooth flow of traffic. cross. Advances in road pavement technology have encouraged researchers to conduct research using palm shell ash (fly ash) as a filler in porous asphalt mixtures. The use of palm shell ash is expected to increase the stability value and have large cavities so that water can pass through the road surface, as well as to reduce palm oil waste in Indonesia. The objectives of this research are 1. To find out the optimum asphalt content value in porous asphalt mixtures, 2. To know the results of using palm shell ash at 0%, 1% and 2% as a filler for porous asphalt mixtures in flexible road pavement. The research method is Marshall and Permeability Testing. The tests that will be carried out on a laboratory scale use an AC-WC hot mix asphalt system with guidance, namely the basics of asphalt concrete road construction. The research results showed that by adding palm shell ash as a filler in making AC-WC type porous asphalt, it showed that the stability value was higher, while the permeability value was lower, meaning that the addition of palm shell ash to the porous asphalt mixture did not have a significant effect because it was smaller. air voids in the mixture. The addition of palm shell ash to the porous asphalt mixture increases the stability value which can increase the ability of road construction to accept loads, but the pavement layer is not permeable and water flows over the surface more slowly.

Most filler materials are natural products such as stone ash which is increasingly limited in quantity and has a high economic value. For this reason, it is necessary to innovate by using alternative replacement materials in the form of waste such as sawdust in an effort to obtain a more economical replacement material and the amount in the field is still large. The purpose of this study was to determine the effect of using wood cutting waste ash filler in AC-BC mixture. This research was conducted using the 2018 Bina Marga Specifications and using the Marshall Test method. The percentage of wood cutting waste ash used was 0%, 10%, 20%, 30%, and 40%. Based on the research results, the optimum asphalt content is 5.8%. The greater the mixture of wood cutting waste ash filler composition, the lower the VMA and VIM values, while the higher the VFA value. The VMA, VFA and Stability values still meet the requirements of the 2018 Bina Marga Specifications. VIM and flow values increased and decreased in each variation of kulim wood ash mixed. For the stability value in the 0% and 10% variations of the culim wood ash mixture, it increased from 1815.261 - 1863.761Kg, but in the 20% - 40% variation it decreased from 1551.979 - 1281.768Kg but still met the requirements of the 2018 Bina Marga General Specifications. The flow value in the 0% and 10% variations increased from 3.20 - 3.87mm, but the 20% - 40% variation also experienced an increase that exceeded the maximum limit of the 2018 Bina Marga Specifications from 4.03 - 4.70mm. In all of the kulim wood ash filler compositions used, only the 0% and 10% variations of kulim wood ash met the requirements of the 2018 Bina Marga General Specifications. Meanwhile, the maximum composition of the culim wood ash filler mixture was obtained in the 10% culim wood ash variation with a VMA value of 16.995%, VIM of 3.891%, VFA of 77.102%, Stability of 1863.761 Kg and Flow of 3.87 mm.

[IN] Penelitian ini bertujuan untuk menganalisis daya dukung tanah pada lokasi pembangunan masjid di Dusun I Pasir Rambah, Kecamatan Rokan IV Koto, Kabupaten Rokan Hulu, Provinsi Riau, dengan menggunakan metode Cone Penetration Test (CPT) atau uji sondir. Pengujian ini dilakukan untuk mengetahui karakteristik lapisan tanah serta menentukan jenis pondasi yang tepat dan aman digunakan. Lokasi Pembangunan masjid ini berada tidak jauh dari aliran sungai, sehingga diperkirakan memiliki muka air tanah yang cukup tinggi dan kondisi tanah jenuh air di lapisan atas. Berdasarkan pengamatan awal di lapangan, lapisan tanah bagian atas berupa lempung dengan kadar air tinggi, yang berpotensi menurunkan kestabilan pondasi apabila tidak dianalisis terlebih dahulu. Data diperoleh melalui pengukuran nilai perlawanan konus (qc) dan hambatan lekat (fs) pada dua titik pengujian hingga kedalaman 10 meter. Hasil analisis menunjukkan bahwa pada titik 1, nilai daya dukung tanah maksimum tercapai pada kedalaman sekitar 2,6–2,8 meter dengan kapasitas izin (Qa) sebesar 2,08 ton/pile untuk penampang tiang 20×20 cm dan 3,25 ton/pile untuk penampang tiang 25×25 cm. Sementara pada titik 2, daya dukung tanah meningkat hingga kedalaman 4,0 meter dengan nilai Qa maksimum sebesar 8,75 ton/pile (20×20 cm) dan 7,5 ton/pile (25×25 cm). Berdasarkan hasil tersebut, pondasi tiang pancang pendek direkomendasikan pada titik 1, sedangkan pondasi tiang dalam atau bored pile direkomendasikan pada titik 2 karena memiliki lapisan tanah keras dengan daya dukung lebih tinggi. Penelitian ini memberikan dasar teknis bagi perencanaan pondasi yang efisien dan aman untuk pembangunan masjid di wilayah tersebut. [EN] This study aims to analyze the soil bearing capacity at the mosque construction site located in Dusun I Pasir Rambah, Rokan IV Koto District, Rokan Hulu Regency, Riau Province, using the Cone Penetration Test (CPT) or sondir test method. The testing was carried out to identify subsurface soil characteristics and determine the most suitable and safe type of foundation. Data were obtained from the measurement of cone resistance (qc) and sleeve friction (fs) at two test points up to a depth of 10 meters. The results indicate that at point 1, the maximum soil bearing capacity occurs at a depth of about 2.6–2.8 meters with an allowable bearing capacity (Qa) of 2.08 ton/pile for a 20×20 cm pile section and 3.25 ton/pile for a 25×25 cm pile section. Meanwhile, at point 2, the soil bearing capacity increases up to a depth of 4.0 meters, reaching a maximum Qa value of 8.75 ton/pile (20×20 cm) and 7.5 ton/pile (25×25 cm). Based on these findings, short pile foundations are recommended at point 1, while deep pile or bored pile foundations are suggested at point 2 due to the presence of dense soil layers with higher bearing capacity. This study provides a technical basis for designing efficient and safe foundations for mosque construction in the study area.
