Risk Analysis of Equipment Loss During Marine Survey Operation by Integrating Fault Tree to Bayesian Network
Get PDFThe process of deploying and towing the survey equipment for several marine survey activities is essential since it visualises the seabed and improves data accuracy. Since the equipment is deployed to an underwater level, the risk arises with the deployment. These risks include potential contact with submerged objects and the seabed, which can result in the loss of equipment and have detrimental environmental consequences. This study aims to analyse the risk-associated factors related to the loss of survey equipment using Fault Tree Analysis (FTA) and Bayesian Network (BN). The constructed FTA was converted into BN to find the relationship between Basic events and simulate the probability of updating Basic events. The sensitivity analysis results of the BN model indicate that "Procedure Failure" is the Basic contributor to the loss of survey equipment. The findings from this study will have practical implications for stakeholders, enabling them to enhance the safety of marine survey activities, particularly by mitigating the occurrence of equipment loss during operational procedures
Cellulose Aerogel with Zinc Oxide for Wound Dressing Application
Get PDFThis research aim is to determine the performance of coconut fiber-based cellulose aerogel impregnated with zinc oxide for wound dressing applications. Cellulose is an alternative material in aerogel synthesis. Cellulose aerogel is the latest third generation in aerogel research which has attracted much attention due to its good prospects, especially in terms of environmental friendliness and price effectiveness. The synthesis of cellulose aerogel begins with the cellulose purification stage through delignification and bleaching, followed by the addition of NaOH-urea solution, freeze drying and the final stage is impregnation with zinc oxide. Zinc oxide (ZnO) has nontoxic, safe and biocompatible properties and functions as an antibacterial agent. The cellulose/ZnO aerogel formed was subjected to performance tests including analysis of porosity, water absorption capacity, water vapor permeability and antibacterial tests. Based on research that has been carried out, it was found that coconut fiber-based cellulose aerogel impregnated with ZnO has a good potential as a wound dressing application. The porosity of the resulting cellulose aerogel can reach above 90% with high water absorption capacity and has a water vapor permeability which increases with increasing cellulose concentration. Antibacterial tests show that the cellulose/ZnO aerogel has good antimicrobial characteristics
Design and build a pond temperature control system and automatic feed for tilapia in aquaponics
Get PDFExpansion of land causes the population and food needs to be unbalanced. One way to overcome this problem is aquaponic cultivation. Aquaponics is a modern practical farming system that integrates plant cultivation systems with the cultivation of aquatic animals. One of the success factors of aquaponics is temperature and automatic feeding of pond water. To get the right temperature for fish, temperature control can be done using the DS18B20 temperature sensor. When the fish pond temperature drops below 28°C, the heater will automatically turn on to raise the pond temperature, and when the pond temperature rises above 32°C, the peltier will light up and start lowering the fish pond temperature. Automatic feeding uses the Real Time Clock (RTC) module as a timer and a servo motor as the opening valve for the fish feed container. The results of this research obtained the relative growth rate (RGR) ratio of fish before and after the control system was installed was 7.14% and 11.2%, respectively. The feed conversion ratio (FCR) values of fish before and after the control system was installed were 12.50% and 21.07%, respectively. The plant growth rate before and after the control system was installed were 22.9% and 33.71%, respectively
Comparison of Three Embankment Reinforcement on Soft Soil, A Case Study of Calang – Simpang Peut Road Section
Get PDFOne of the road damages caused by problematic soil is found on the Calang - Simpang Peut Road Section. Soil testing data shows that soft soil exists at a depth of zero meters, up to five meters. The damage is being repaired using a Modified Cakar Ayam (CAM) system. The CAM system is built on a road embankment. Using the CAM on the top of the road embankment has a settlement problem that will cause non-uniform settlement. This study reviews three alternatives that have been proven effective and efficient in fixing road embankment failures on problematic soils. These alternatives are geosynthetic reinforcement, geosynthetic reinforcement with prefabricated vertical drain (PVD), and encapsulated stone columns. This research will analyze the three alternatives based on their efficiency and effectiveness in treating the damage. The results of the calculation analysis show that the geosynthetic-reinforced embankment is the most effective alternative design. The alternative can also reduce the execution time by 42% and cost by 43% compared to the CAM system. However, a subgrade improvement alternative with encapsulated stone columns increases the execution time by 20% and cost by 25% compared to the CAM system, and using a PVD alternative is not recommended to repair the road embankment on this road section

Strategi Pengembangan Community Based Tourism Berdasarkan Peran Stakeholder Masyarakat (Studi Kasus: Kawasan Wisata Peneleh Kota Surabaya)
Get PDFKelurahan Peneleh, yang terletak di pusat Kota Surabaya, mempunyai daya tarik wisata berupa peninggalan sejarah. Dinamika perkembangan pariwisata telah terjadi di kampung ini yang ditunjukkan melalui peningkatan jumlah kunjungan wisatawan secara bertahap setelah mengalami penurunan signifikan akibat pandemi Covid-19. Dalam mendukung pengelolaan pariwisata oleh warga Peneleh, telah terdapat Kelompok Sadar Wisata (Pokdarwis) yang menjadi modal utama perwujudan Community Based Tourism (CBT). CBT merupakan pariwisata yang melibatkan partisipasi aktif dan keterlibatan masyarakat lokal dalam pengembangan kegiatan pariwisata. Permasalahan ditemukan masih lemahnya keberadaan Pokdarwis serta rendahnya partisipasi warga lokal dimana dapat mengancam eksistensi Peneleh kedepannya. Dalam menjaga eksistensinya, ketahanan masyarakat sebagai pelaku industri pariwisata dibutuhkan untuk beradaptasi, pulih, dan bertahan dari dinamika pariwisata yang terjadi seperti pandemi dan modernisasi perkotaan. Adapun, masyarakat sebagai stakeholder yang berperan dalam pengembangan pariwisata, memiliki pengaruh dan kepentingannya masing-masing. Guna mendukung pariwisata berkelanjutan, perlu mengetahui kondisi keduanya (ketahanan serta peran masyarakat) sebagai dasar dalam merumuskan strategi pengembangan CBT. Tujuan dari penelitian ini adalah untuk memformulasikan strategi peningkatan ketahanan masyarakat ketika menghadapi situasi unpredictable yang mengancam eksistensi Peneleh sesuai dengan peran stakeholder masyarakat dalam pengembangan pariwisata. Data penelitian diperoleh melalui studi literatur, observasi non partisipan, dan wawancara mendalam kepada responden masyarakat melalui teknik snowballing dan purposive sampling. Data yang diperoleh dianalisis menggunakan teknik skoring statistik dan content analysis. Pokdarwis merupakan stakeholder yang paling berkepentingan dan berpengaruh serta berperan sebagai konseptor, regulator, fasilitator, implementer, koordinator, dan akselerator. Ketahanan ekonomi paling rendah, begitu juga dengan ketahanan sosial dan kelembagaan yang ketiganya di bawah rata-rata ketahanan keseluruhan. Dengan demikian, perumusan strategi difokuskan untuk meningkatkan ketiga aspek tersebut, yakni terkait dengan: pembentukan komunitas bisnis, pembangunan balai kreatif dan koperasi pariwisata, pengadaan lokakarya kreatif, serta pengaturan monitoring dan evaluasi partisipatif
