Abstract

This research aim to settled high concentrated surfactants using calcium hydroxide. Using a jar test, the concentration of surfactants were measured. The batch test was started using a low concentration of surfactants at low pH. The results showed that calcium hydroxide was able to remove 95.16 % of surfactants. Which proved good performance of the chemical agent. This indicated that the chemical can be used to treat detergent rich content water or other effluent rich in surfactant content.

Abstract

Tarakan adalah kota penghasil minyak yang telah dikenal sejak 1896. Derrick didefinisikan sebagai fasilitas pengeboran minyak bumi. Prototipe derrick dimodelkan dengan elemen rangka 3D dalam SAP2000. Tiga standar telah digunakan seperti AISC- ASD 1983; AISC-LRFD 1993; dan AISC 2010. Kombinasi beban angin (W) dan gempa (E) telah dibandingkan. Analisis tekuk tunggal dan keseluruhan telah dipertimbangkan. Hasil penelitian menunjukkan bahwa struktur derick memenuhi persyaratan stabilitas dan kekuatan. Pengaruh kombinasi beban angin (W) pada struktur derek lebih signifikan (9,45%) daripada beban gempa (E). Beban tekan aksial terbesar maksimum 9,37 kN pada elemen kaki (legs). Kegagalan tekuk tidak terjadi pada struktur derrick. Beban kritis (Pcr) tercatat 700,45 kN (Euler), 693,41 kN (tunggal), dan 219,67 kN (struktur).  Kata Kunci: tekuk, on shore, kapasitas, angin, rig

Abstract

Kenaikan muka air laut (Sea Level Rise, SLR) merupakan salah satu dampak signifikan perubahan iklim yang beriimplikasi langsung pada keberlanjutan infrastruktur pesisir. Penelitian ini bertujuan memprediksi kenaikan muka air laut di Kota Tarakan periode 2025-2100 dengan menggunakan data historis 1994-2024 dari Copernicus Climate Change Service yang diolah menggunakan perangkat lunak ODV (Ocean Data View). Analisis dilakukan menggunakan distribusi probabilitas Gumbel dan Weibull yang menghasilkan persamaan prediksi berbasis input tahun, sehingga memudahkan perencana infrastruktur pesisir untuk menentukan elevasi desain tanpa melakukan perhitungan ulang. Hasil menunjukkan bahwa model Gumbel memberikan estimasi yang lebih tinggi (kondisi terburuk) dibandingkan model Weibull (kondisi terbaik), keduanya memiliki koefisien determinasi tinggi (R2 ≥ 0,94). Proyeksi hingga tahun 2100 mempertimbangkan kenaikan muka air laut maksimum mencapai 2,44 m (Gumbel) dan 2,40 m (Weibull). Temuan ini menjadi acuan teknis dalam perencanaan bangunan pelindung pantai seperti revetment, detached breakwater, dan groin, serta dalam penyesuaian desain dermaga dan sistem drainase pesisir. Kontribusi utama penelitian ini adalah penyediaan persamaan prediksi SLR yang dapat langsung diintegrasikan ke perencanaan teknik sipil, khususnya pada wilayah pesisir tropis yang rentan terhadap perubahan iklim.

Abstract

Costal abrasion in Tarakan City requires a protection system that is not only structurally effective but also economically feasible and implementable through community-based approaches. This study aims to design a modular revetment structure using recycled tires filled with concrete and compacted sand based on a design-based analytical approach. Wave transformation analysis at a depth of -0.52 meters indicates significant wave heights ranging from 1.19 to 1.70 meters, which serve as the primary basis for stability calculations using the Hudson formula with a conservative stability coefficient 1.25. The results show that a single concrete-filled tire unit weighs approximately 285 kg, and five units are required to form the primary armor layer with a height of 1.20 meters. To achieve the design crest elevation of +1.95 meters relative to HHWL, additional secondary protection layers and a toe protection system made of quarry stones were incorporated, resulting in a total structural height of 2.40 meters. Sensitivity analysis indicates that variations in significant wave height strongly influence the required weight of armor, whereas changes in material density produce more moderate effects. Compared with conventional stone revetments, the modular tire system offers greater flexibility, ease of installation without heavy equipment, and supports circular-economy principles through the reuse of waste tires. The implementation plan adopts a participatory appriach by engaging local fishermen and coastal communities in material collection, assembly, and maintenance activities. This study provides a sustainable, low-cost, and adaptive alternative for coastal protection that can be replicated in other shoreline areas with similar environment conditions.
