Abstract

Fires that occur in a building often cause damage to its structural elements. This study aims to determine the compressive strength of coconut fiber concrete after burning with concrete quality design fc' 20 MPa. This research was conducted by simulating the condition of burning concrete through a cylindrical medium measuring 5 cm x 5 cm with a total of 39 samples. The test was carried out at the age of 28 days by placing the sample into the drum and then burning it with a temperature variation of 200°C and 300°C. The sample burning durations were 30 minutes, 60 minutes, and 90 minutes. Samples that reach the specified temperature are then cooled by pouring and without pouring. Compressive strength test results for a temperature of 200oC with watering treatment, duration of 30 minutes 14.33 Mpa, duration of 60 minutes 10 MPa, and duration of 90 minutes 8.42 MPa. For the treatment without watering with a duration of 30 minutes 15.65 Mpa, 60 minutes 13.15 MPa, and 90 minutes 11.23 Mpa. Compressive strength at 300oC for watering treatment, 30 minutes 11.08 MPa, 60 minutes 8.71 MPa, and 90 minutes 5.31 MPa. Whereas for conditions without watering with the same temperature, the duration was 30 minutes 13.44 MPa, 60 minutes 12.26 MPa, and 90 minutes 8.71 MPa. As a comparison, the compressive strength of coco fiber concrete without burning is 20.39 Mpa. From the data above, it can be concluded that the longer the combustion process takes place, the strength of the coco fiber concrete will decrease by an average of more than 20%. According to PBI 1971 Chapter 4.8 Paragraph 1 states the concrete strength requirement is equivalent to 80% of the required compressive strength value.

Abstract

The refurbishment of the Pasir Putih Beach entryway was executed to augment the destination's allure and improve the visiting experience. This project employed a Participatory Action Research (PAR) methodology, engaging local communities, government entities, and stakeholders in the planning, execution, and assessment phases. The activities encompassed problem identification, design planning, validation, implementation, and evaluation. The redevelopment outcomes embody local character via traditional ornamental features, creative illumination, and ancillary amenities such informational displays and seating arrangements. The engagement of local communities enhanced their sense of ownership and generated economic prospects during and subsequent to the rehabilitation. The evaluation results indicated a rise in visitor numbers and satisfaction with the renovation efforts. This program enhanced the aesthetic, functional, and sustainable design of Pasir Putih Beach, solidifying its status as a premier destination in Kolaka Utara. This exercise illustrates that a participative approach can facilitate sustainable tourist development

Abstract

Peningkatan aktivitas operasional kapal penyeberangan dan kendaraan bermotor di Pelabuhan Kolaka, yang merupakan hub transportasi penting di Sulawesi Tenggara, berkontribusi secara signifikan terhadap emisi gas buang, yang berdampak pada kualitas udara dan kesehatan masyarakat. Penelitian ini mengestimasi beban emisi dari aktivitas kapal penyeberangan serta bongkar muat kendaraan bermotor di Pelabuhan Kolaka pada tahun 2023. Estimasi dilakukan melalui pengumpulan data primer dan sekunder, yang mencakup karakteristik kapal, konsumsi bahan bakar, dan aktivitas kendaraan, serta penerapan faktor emisi untuk menghitung beban emisi. Polutan utama yang diamati meliputi nitrogen oksida (NOx), karbon monoksida (CO), partikel halus (PM10), sulfur oksida (SOx), dan senyawa organik volatil non-metana (NMVOC).   Hasil penelitian menunjukkan bahwa aktivitas kapal mendominasi emisi, dengan NOx sebagai kontributor tertinggi sebesar 224,78 ton/tahun, diikuti oleh CO (39,91 ton/tahun) dan PM10 (21,56 ton/tahun). Emisi NMVOC dan SOx masing-masing tercatat sebesar 14,03 ton/tahun dan 5,38 ton/tahun. Sementara itu, aktivitas kendaraan bermotor selama proses bongkar muat menambah emisi dalam jumlah yang lebih kecil, terutama CO (509,88 kg/tahun) dan NOx (183,72 kg/tahun).
