Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh penambahan abu sekam padi (ASP) dan fly ash (FA) terhadap berat jenis tanah Puru yang berasal dari Kelurahan Tua Tunu, Bangka Belitung. Tanah Puru merupakan jenis tanah laterit yang memiliki daya dukung rendah akibat sifatnya yang mudah menyerap air. Pengujian dilakukan di laboratorium dengan metode analisis ukuran butir dan uji berat jenis menggunakan piknometer, dengan variasi campuran ASP dan FA sebesar 5%, 10%, dan 15%, serta kombinasi keduanya. Hasil analisa ukuran butir menunjukkan bahwa tanah tergolong pasir bergradasi baik, dengan kandungan pasir >98% dan nilai Cu > 6 serta Cc antara 1–3. Pada uji berat jenis, penambahan ASP secara bertahap menurunkan nilai berat jenis tanah dari 2,665 (tanpa campuran) menjadi 2,446 pada kadar 15%. Sebaliknya, fly ash meningkatkan nilai berat jenis hingga 2,652 pada kadar 15%. Namun, ketika kedua bahan dicampur (FA 15% + ASP 5%), nilai berat jenis menurun menjadi 2,556. Hal ini menunjukkan bahwa ASP yang lebih ringan mampu menetralkan efek peningkatan berat jenis oleh FA. Penelitian ini menyimpulkan bahwa komposisi material tambahan mempengaruhi nilai berat jenis tanah dan dapat digunakan untuk mengatur kepadatan tanah sesuai kebutuhan rekayasa.

Abstract

Soil conditions are a critical factor influencing the feasibility and success of construction projects, especially for infrastructure that interacts directly with the ground, such as foundations and slopes. Geotechnical issues like excessive settlement and shallow translational landslides often occur due to insufficient understanding of soil characteristics. Soils with high clay content or low density are prone to volume changes and water saturation, which can threaten structural stability. This study aims to examine soil characteristics at the research site by integrating field tests (Cone Penetration Test/CPT) and laboratory tests to evaluate soil bearing capacity and slope instability potential. The methods included CPT at seven points and laboratory tests on seven soil samples to analyze physical and mechanical properties, such as grain distribution, Atterberg limits, and shear strength parameters. CPT results showed a dominance of silty sand with very loose to loose density in the upper layer (0–2 meters) and medium to dense density in deeper layers (>6 meters). Laboratory tests identified variations in soil classification, including silty sand (SM), silt (ML), and high-plasticity clay (CH), with low cohesion (6–10 kPa) and internal friction angle (4.85°–8.38°). Data integration revealed a high landslide risk in the upper layer due to water saturation, necessitating mitigation strategies such as deep foundations and effective drainage systems. This research provides significant contributions to safe and sustainable construction planning in areas with similar soil conditions.

Abstract

Soil compaction is a critical phase in construction projects, particularly those requiring long-term structural stability. The compaction process aims to increase soil density, enabling the soil to support structural loads without excessive settlement. This study was conducted to evaluate the effectiveness of soil compaction used as fill material in an industrial development project in Southeast Sulawesi. A quantitative approach was employed by combining laboratory testing using the standard Proctor method and field evaluation using the sand cone method. Soil samples were directly taken from the project site and tested in the laboratory to determine the maximum dry density (γdmax) and the optimum moisture content (wopt). Laboratory results indicated a γdmax of 1.69 gr/cm³ and a wopt of 28.80%. Subsequently, sand cone tests were performed at eight field locations after the compaction process was completed. The results showed that the field degree of compaction ranged from 77.8% to 90.4%, which is below the minimum technical standard of 95%. This discrepancy is attributed to excessive moisture content and a lack of control in field execution. The study highlights the importance of synchronizing laboratory data with field implementation. The findings provide valuable recommendations on moisture control, appropriate equipment selection, and operator training to improve soil compaction quality in future construction projects.

Abstract

Fondasi Tower crane merupakan elemen struktural penting dalam proyek konstruksi yang harus mampu menahan beban dinamis dan statis yang terjadi selama operasional. Penelitian ini bertujuan untuk menganalisis desain awal fondasi Tower crane dan mengidentifikasi kebutuhan revisi berdasarkan hasil investigasi tanah yang lebih mendalam. Metode yang digunakan meliputi perhitungan daya dukung tiang pancang dengan metode Bahan, Skempton, dan Meyerhoff serta evaluasi stabilitas pilecap menggunakan analisis tegangan geser dan lentur. Hasil penelitian menunjukkan bahwa desain awal fondasi tidak memenuhi persyaratan daya dukung akibat kesalahan asumsi kondisi tanah, sehingga revisi dilakukan dengan menambah jumlah tiang pancang dan menyesuaikan dimensi pilecap. Revisi desain ini berhasil meningkatkan daya dukung fondasi hingga mencapai kestabilan yang memenuhi standar keamanan konstruksi sesuai dengan SNI 2847:2013.

Abstract

Air transportation has an important role in supporting regional economic growth, especially for areas with tourism and trade potential such as Singkawang City. This study analyzes the contribution of improving connectivity and developing flight routes at Singkawang International Airport to local economic growth. Using qualitative descriptive research methods, data is collected through literature studies, documentation, and secondary data from official sources. The results of the study show that this airport has the potential to serve domestic and international routes, and is an important factor in strengthening the trade and tourism sector. However, challenges such as low flight frequencies, lack of airline incentives, and lack of intermodal integration remain major obstacles. Recommended strategies include on-demand route development, integration with local leading sectors, partnerships between stakeholders, and the use of spatial data for route planning. This study confirms that planned and adaptive air connectivity can be a significant driver in realizing regional economic development in an inclusive and sustainable manner.
