Aktivitas penangkapan ikan oleh nelayan di Kabupaten Kebumen mengalami kendala utama terkait dengan kondisi oseanografis dan ketidakpastian musim penangkapan ikan. Saat tidak musim, sebagian nelayan memiliki mata pencaharian lain yaitu bertani, beternak, dan lainnya. Namun tidak semua nelayan memiliki kemampuan tersebut, banyak nelayan yang menggantungkan hidupnya hanya sebagai nelayan. Tujuan penelitian ini yaitu mengidentifikasi potensi wilayah sebagai alternatif kegiatan ekonomi bagi nelayan dan memberikan rekomendasi mata pencaharian alternatif yang tepat bagi nelayan di Kabupaten Kebumen, contoh kasus di Desa Jogosimo. Pengumpulan data peluang kegiatan ekonomi alternatif dilakukan melalui survei potensi wilayah dan studi pustaka. Hasil tersebut selanjutnya dilakukan focus group discussion (FGD) untuk mendapatkan masukan terkait dengan pandangan nelayan terhadap alternatif mata pencaharian tersebut. Analisis data dilakukan secara deskriptif berdasarkan hasil survei lapang dan FGD. Hasil identifikasi lapang dan studi pustaka diperoleh kegiatan ekonomi alternatif yang dapat dilakukan nelayan yaitu kegiatan penangkapan ikan di muara sungai dengan bubu, budidaya/pembesaran kepiting bakau, dan wisata sungai. Hasil FGD diperoleh masukan perlunya inovasi agar alat tangkap bubu tidak hilang saat arus sungai deras. Kondisi mangrove di Desa Jogosimo perlu dilakukan penanaman kembali agar populasinya lebih tinggi, sehingga budidaya ataupun pembesaran kepiting bakau dapat dilakukan. Rekomendasi yang dapat diberikan adalah perlunya mengembangkan wisata sungai melalui integrasi kegiatan penangkapan ikan, pemeliharaan dan pmbesaran kepiting bakau, serta wisata kuliner dan pemasaran produk lokal.

Authors: Abbas Mohammad Fadhil , Makkiyah Haider M. 
Published: May 2024

For projects such as airports and road paving, an appropriate foundation must be developed in Sabkha soil, which requires a trustworthy assessment of soil-bearing capacity. When heavy traffic is expected to result in substantial wheel loads throughout pavement construction and maintenance, the plate load test helps solve these issues with subgrade and sub-base layer design. This work aims to investigate and assess the geotechnical behavior regarding soil strata from one area in southern Iraq: Sabkha. Conversely, a comparison is made between subgrade response modulus and soil-bearing capacity determined by field plate load tests and traditional laboratory investigations. The data demonstrated that the values related to Ks in the consolidation test rose as a ratio of pre-consolidation pressure of 45% and dramatically dropped with an increase in applied stress that is vertically applied below pre-consolidation stress. Furthermore, PLT data demonstrated that when pressure was applied, the modulus of the subgrade reaction did not follow a regular pattern. At the beginning of the loaded stage, after the pre-consolidation stress, Ks values at testing points 2 and 3 were high. After that, Ks abruptly decreased, particularly when the applied pressure surpassed the pre-consolidation stress before being constant again. A detailed discussion is given on the effects of stress distribution and test conditions on the elasticity stress curve's shape and the subgrade reaction modulus.

Abstract
Superelastic NiTi (Nitinol) alloy is a smart material applied in the biomedical sector for devices, such as stents, implants and orthodontic wires. Nevertheless, after surgery, one of the major causes of failure, which requires the explantation of the device, is linked to bacterial infections. Therefore, development of antibacterial materials becomes an important task in the biomedical field. In this light, the present study investigates the integration of pseudoelasticity of Nitinol withan antibacterial response for realizing advanced implantable devices.

Abstract
Transcatheter heart valve replacement is a key advancement in the cardiovascular device industry and provides an alternative to open surgical procedures for patients that suffer from severe symptomatic stenosis and/or regurgitation. The functions and boundary conditions of the four heart valves are unique and must be considered separately. It is essential that the structural durability of these high-risk valve replacement implants is thoroughly assessed through testing and analysis. As such, ISO 5840 outlines a comprehensive device durability approach that incorporates worst-case boundary conditions, computational stress/strain analyses, and benchtop fatigue testing. The present study is focussed on 100,000,000-cycle fatigue testing of custom-designed “diamond-shaped” coupons of process-optimized high purity VAR/EBR Nitinol. Benchtop testing was coupled with finite element analysis (FEA) and microstructural characterization to provide an in-depth understanding of durability.

Published: May 2024

Abstract
The ancient art of origami enables to create 3D shapes from a flat sheet of paper. This concept can be applied to a planar matrix composed of interconnected tiles, which can be self-folded and unfolded using actuated SMA bridges. Origami-inspired self-folding structures offer several advantages, including rapid in-plane fabrication, reduced assembly time, and lightweight designs with high rigidity. Previous research has primarily concentrated on macro-sized demonstrators that have proven advanced functionality in a variety of fields, including robotics and aerospace. In this work, we extend this concept to the microscale by creating a network of self-folding microactuators that can be programmed and controlled through local Joule heating. Our previous concepts faced limitations for reversible latching of tiles in their position after actuation. This paper presents the design, fabrication, and characterization of an origami-inspired bistable microdevices that utilize antagonistic SMA microactuators for bi-directional self- folding and heatable magnetic SMA films for reversible magnetic micro-latching.
Molecular Dynamics Simulations of Microstructural Effects on Austenite-Martensite Interfaces in NiTi
Authors: Plummer Gabriel , Mendelev Mikhail I. , Lawson John W. 
Published: May 2024

Abstract
The formation and migration of austenite-martensite interfaces plays a key role in the reversible martensitic transformations of shape memory alloys (SMAs). How these interfaces interact with the SMA microstructure is a primary determining factor in important functional properties such as hysteresis and transformation span. Therefore, successful microstructural engineering of SMAs requires in-depth knowledge of interface behavior. The rapid nature of martensitic transformations makes experimental observations of moving interfaces challenging. Molecular dynamics (MD) simulation is a unique tool which can probe the atomic-scale details of austenite-martensite interfaces as they migrate and interact with different microstructural features. While MD simulations allow access to atomic-scale mechanisms, they are limited in time scale, typically to nanoseconds. This limitation creates problems when focusing on the entire transformation process in SMAs, specifically nucleation of new phases. To trigger nucleation on the nanosecond time scale, MD simulations must be performed so far from equilibrium that their relevance to experiment becomes questionable. Here, we demonstrate new MD simulation techniques to generate energetically preferred austenite-martensite interfaces in NiTi under near-equilibrium conditions. We then take advantage of this approach to probe interface behavior under conditions relevant to experiments. Our results demonstrate how austenite-martensite interfaces behave with dramatic differences in single crystals compared to more realistic microstructures containing features such as grain boundaries and precipitates. We identify trends in interface behavior which can be utilized to inform microstructural engineering approaches for SMAs.
Similar and Dissimilar Joining of Nitinol through Transient Liquid Phase Bonding
Authors: Cao Zhaoxi , Price Samuel Grant , McCue Ian 
Published: May 2024

Abstract
Nitinol, a near-equiatomic nickel-titanium alloy, is one of the most widely used shape memory alloys (SMAs) due to its excellent mechanical behavior, corrosion resistance, and large recoverable strain limit (~8%). For these reasons, nitinol has been fielded in many aerospace applications, including self-deploying actuators, folding aircraft wings, and rover tires. However, these applications require joining nitinol to support structures which are often a different alloy class. Traditional welding methods, when applied to nitinol, lead to the formation of brittle intermetallic phases, reduced strength within the joint region, and decreased functional performance (such as recoverable strain and heterogeneous transformation temperatures). Thus, dissimilar joining of nitinol remains a grand challenge in the ultimate use of these materials, and advances in joining technologies will greatly expand the potential applications of SMAs.

Published: May 2024

Abstract
For producers and end-users of high-performance Nitinol, a material that functionally depends on everything that is done to it, it is critical to keep pace documenting the connection between producer-evolved grades and critical subcomponent performance. In Nitinol, the latitude of the industrial standard material specification ASTM F2063 should be continuously plied, and performance outcomes weighed against end-use demands as an aid to relevant use recommendations and requirements development. The current standard specification for wrought NiTi requires maximum oxygen and carbon levels of 400 ppm and maximum observed contiguous particle- void-assembly (PVA) lengths not exceeding 39.0 microns measured in longitudinally mounted specimens. Performance variation across impurity- and PVA length-compliant nitinol grades, especially with respect to structural fatigue, is well documented where each new study gives a snapshot in time that depends on initial chemistry and PVA distributions, processing history, test coupon geometry, fatigue test boundary conditions, and other factors. This study is a small step toward keeping pace with the connection between nitinol grades and tubing performance.

Published: May 2024

Introduction: There is a high incidence of open fractures accounting 23% of all tibial fractures. The minimal soft tissue and precarious blood supply of the shaft of tibia make these fractures vulnerable to complications. The treatment should be decided through thoughtful analysis for personality of injuries and the status of the soft tissue. Intramedullary nailing allows stable fixation with minimal soft tissues dissection and preserve the soft tissue and allows early joint motion with higher rate of union. The purpose of our study was to find the outcome of open tibial fractures lower than Gustilo type IIIb, that were treated by unreamed solid interlocking intramedullary nails.
Methods: A descriptive cross-ectional study was conducted from December 2021 to June 2023 after taking approval from ethical committee. All 34 patients treated with solid interlocking intramedullary nail, without reaming for open tibial fracture during 18 months period were included in the study. Final follow up was done at one year and the outcome was assessed by Modified Ketenjian’s criteria.
Results: The mean time of union rate was 15.82±3.95 weeks. Complications were: superficial infections in 4 (11.76%) patients and deep infection in 1 (2.94%) patient. Using Modified Ketenjian's Criteria, 26 (76.47%) patients had an excellent result followed by good in 7 (20.59%), fair in 1 (2.94%) and there was no case with poor outcome.
Conclusions: Solid intramedullary interlocking nail is an effective treatment with minimal soft tissue dissection for open tibia fracture less than GA III B as it provides stable fixation with early mobilization and provides a high rate of union, less complication and early return to function.
