The physiological stage of mango maturity at harvest affects fruit quality at the time it is commercialized. The objective assessment of the mango maturity stage at harvest remains a challenge because of the multiple interactions between the visual aspect, the physicochemical composition, and the morphology of the fruit. This study aims to quantify the optimal harvest date to guarantee the maturity and quality of mango cv. ‘Kent’. In this study, which took place in Korhogo in northern Côte d’Ivoire, the maturity stage and the quality of fruits were measured on 240 Kent mangoes harvested at four different harvest dates (90, 95, 100, and 105 days after flowering). A morphological, physical, and chemical characterization (length, width, mass, soluble sugar content, dry matter, skin appearance, and mass loss) was carried out at each date on 30 fruits at harvest and 30 fruits after ripening at room temperature. The number of days necessary for ripening was quantified. The results showed that the optimal harvest date is 100 days after flowering for Kent mangoes in Côte d’Ivoire. Mangoes harvested at this date developed better organoleptic characteristics (less wrinkled skin, lower mass losses, and a shorter ripening time). Assessment of the harvest date, guaranteeing better ripening of the fruit, is of utmost importance for organizing harvests in the mango sectors in West Africa, and especially in Côte d’Ivoire.

Nowadays food industries were concentrating on substituting the use of synthetic natural “green” antioxidants. Therefore, the present study focused on lipid oxidations in dried salmon (Salmo salar) with and without natural antioxidants (garlic powder, cinnamon) during different storage conditions, and a comparison was made with a synthetic antioxidant Butylated hydroxytoluene (BHT). Minced salmon fillet mass was divided into four equal parts and each part was treated with natural antioxidant under study except the control. Each of these four parts was dried in two different ways, half portion oven-dried and the other half portion freeze-dried. After 24 weeks, these samples were tested for peroxide value (PV), Thiobarbituric acid reactive substances (TBARS), total carbonyl content/water-soluble protein. According to the peroxide value (PV) results, it was noticed that the BHT was found to be the most effective antioxidant, followed by garlic and cinnamon for oven-dried salmon. Cinnamon was found to be more efficient than garlic in minimizing PV formation in freeze-dried salmon. In general, the initial study showed that freeze-drying was more efficient than oven drying. On the other hand, total carbonyl content for oven-dried salmon treated with cinnamon, garlic, and BHT, was found to be similar to the untreated salmon. Freeze-dried antioxidant treated salmon was generally found to possess more carbonyl content over time compared to the oven dried treated salmon.

Published: April 2021

Sigorta, insanoğlunun kendini güvende hissetme güdüsüyle doğmuştur. Yarınların ne tür tehlikeler getireceğini kestiremeyen bireyler ve işletmeler, oluşacak bu risklere karşı kendilerini emniyete almak istemektedirler. Sigortacılık sistemi sayesinde gerçekleşmesi muhtemel ekonomik kayıplar asgari düzeyde tutulmaktadır. Ancak geliştirilen bu sigortacılığın temeli faizli bir model üzerine kurulmuştur. Bu model garar (belirsizlik), riba (faiz), gabar (kumar), risk transferi, toplanan primlerinden faizli yatırım araçlarında değerlendirilmesi üzerine inşa edildiği için İslâm hukuku açısından kabul görmemektedir. İslâm dünyasının ihtiyacına binaen farklı bir sisteme ihtiyaç duyulmuş ve alternatif bir model olarak faizden uzak, İslami usul ve prensiplere uygun bir şekilde geliştirilen alternatif sigortacılık sistemi olan katılım sigortacılığı geliştirilmiştir. Katılım sigortacılığı, İslami finans enstrümanlarından birisi olup İslam’ın temel prensiplerine uygun, tarafların risk paylaşımını esas alan, yardımlaşma ve dayanışmaya dayanan bir sigorta sistemidir.
Son yıllarda gerek dünyada gerekse ülkemizde ciddi büyüme ivmesi yakalayan İslami finans uygulamaları ve ürünlerinden katılım sigortacılığı, gün geçtikçe daha çok önem kazanmaktadır. Bu öneme binaen katılım sigortacılığa sektöründe faaliyet gösteren şirket sayısı artmış ve sektörün büyüme ivmesi hız kazanmıştır. Çalışmada; katılım sigortacılığı uygulamaları hakkında genel bilgiler verilerek katılım sigortacılığının Türkiye’deki gelişim durumu ele alınmıştır. Böylece Türkiye’de faaliyet gösteren katılım sigortacılığının mevcut durumuna ve gelişimine yönelik teorik bir çerçeve çizilmiştir.

Published: April 2021

This study investigates entropy generation due to the unsteady boundary layer flow of an Oldroyd-B nanofluid past a Riga plate. The velocity, temperature and concentration fields are obtained and the flow equations solved numerically using the spectral collocation method with overlapping grids. The local entropy generation distribution is obtained by solving the entropy generation equation numerically. Sensitivity and convergence analysis is performed to demonstrate the accuracy and convergence of the numerical method. The effect of principal flow parameters on entropy generation is investigated and it is established that entropy generation is directly proportional to the width of the Riga plate, Brinkman number, Prantl number and the Brownian motion parameter. It is further shown that the entropy generation is inversely proportional to the Eckert number and Deborah number in relaxation time. The range of parameter values were obtained from the reported literature. The current study may have applications of physics, including in the design of both cooling and heating devices.
A SYSTEMATIC GRAPHICAL METHOD FOR SYNTHESIS OF HEAT EXCHANGER NETWORKS

Published: April 2021

Heat exchanger networks (HENs) play a significant role in the energy conservation of any process industry. The HENs are used to maximize heat recovery by exchanging heat between hot and cold process streams. Therefore, the optimum design of HENs is extremely important to reach the maximum efficiency of energy systems. Many graphical methods have been developed during the last four decades for synthesizing of heat exchanger networks (HENs). However, most of these methods have only been evaluated for retrofitting design of HENs. In the grassroots design situation, these methods are often complicated and tedious. This paper introduces a new and simple graphical approach for HEN grassroots design. The new approach based on a single graph called Supply-Target Diagram (ST-D). The ST-D is formulated by plotting supply temperatures versus target temperatures of streams. Streams matching can easily be applied in the ST-D and splitting of streams is clearly visualized and evaluated. A case study is used to illustrate the application of the new graphical method for grassroots design of HENs.
PARAMETRIC EFFECTS ON THE PERFORMANCE OF AN INDUSTRIAL COOLING TOWER
Authors: BAMİMORE O. T. , ENİBE S.o. , ADEDEJİ Paul. A.
Published: April 2021

Sensible and latent heat rejection from heat engines is of high necessity for system efficiency and continuous
production. The cooling tower is one of the major heat-exchanging systems used for cooling industrial heat systems
by intimately mixing hot water with cooling air. Optimal operating conditions and parameters of the system are highly
essential for its effectiveness and efficiency. This study used the Poppe model to evaluate selected thermodynamic
relations of a rectangular counter-flow industrial cooling tower of a steel rolling mill using the system’s inlet and outlet
data as initial conditions. The effect of increasing the water temperature on the air moisture content, Merkel number,
and specific enthalpy was studied across the fills of the cooling tower. Air moisture content, Merkel number and
specific enthalpy of the system increase with increasing water temperature. However, while other variables reach a
stationary point at half the nodal segments, the specific enthalpy increases across the fills in the system. It was
concluded that the use of nano particles with high heat removal rate could increase the efficiency of the system. Also,
an increase in the quantity of the makeup water of a force draft system is recommended towards increasing the system
efficiency.
Numerical Simulations of a PV Module with Phase Change Material (PV-PCM) under Variable Weather Conditions
Authors: Aneli Stefano , Arena Roberta , Gagliano Antonio
Published: April 2021

The electrical efficiency of photovoltaic (PV) modules can be improved through the cooling of the PV. Among the passive cooling strategy, one of the most promising concerns the use of phase change materials (PCMs) to decrease the operative temperature of a PV panel. This paper investigates the performances of a conventional PV panel in which two organic PCMs are added (PV-PCM) to reduce the temperature rise of PV cells and consequently to increase the electrical performances. With this aim, unsteady numerical simulations have been carried with Ansys Fluent software using a two-dimensional simplified geometry for the PV modules with the PCM is incorporated (PV-PCM), as well as for the benchmark PV module. The numerical simulations have allowed evaluating the PV cell temperatures, the power production, as well the PCM thermal behavior. As regards this latter aspect the dynamic analysis has evidenced the need to extend the time of simulation at least for two days in such way to take into account of the degree of solidification achieved during the night by the PCM materials. PCM with low melting temperature cannot complete solidifying during the night and so the heat stored during the day will be lesser than the theoretical one. The results of this study pointed out that the PV-PCM units allow achieving higher performances in comparison with a conventional PV module, especially during the hottest months. An increase in the peak power of 10% and of 3.5% of the energy produced all year round is attained.

The article discusses current issues related to the development of an information optical Smart technology for distance learning of Honeywell's distributed Experion PKS control system for the oil and gas industry. About 70 % of industrial accidents are caused by the human factor through the fault of operators. The work of operators consists in monitoring and managing high-tech proc-esses through mnemonic scheme circuits and is characterized by increased tension in the visual apparatus, as well as general fatigue and loss of concentration. The innovative personalized tech-nology of distance learning takes into account the peculiarities of students' vision by adjusting the color supply of educational material and the dynamic presentation of information depending on the person's psychotype and is based on the use of cognitive, optical, multi-agent technologies, as well as ontological and immuno-network approaches. The development of cognitive mnemonic schemes is carried out taking into account these features, which allows one to reduce the load on the visual apparatus and increase the effectiveness of teaching practical skills when working with mnemonic schemes. An artificial immune systems approach is used to predict and evaluate the learning process and promptly adjust the knowledge obtaining process. A modified algorithm for the functioning of a distance learning system based on the use of optimization algorithms for arti-ficial intelligence and an algorithm for immuno-network modeling has been developed. General principles of creating mimic diagrams and existing Honeywell mnemonic schemes are considered. An example of the implementation of the proposed remote technology is presented and results of the simulation of cognitive mnemonic scheme for various categories of students with special needs are discussed.

Published: April 2021

During COVID-19, many collaborative research teams and community partners pivoted to undertake their work in a virtual way. In this discussion, we capture the mechanics, logic, and situations under which virtual methods became relevant to applied interdisciplinary work. Using a shared voice, we chart the nuances of training and research through the redesign, the reimagining of research protocols, and the nuanced cultural gaps that exist between virtual connection and in-person visiting with community partners, Métis Knowledge Keepers, and experts. Through referencing our reflexive archive of experiences, emails, fieldnotes, and meeting minutes, we address how our attempt to simulate virtual informed consent has consequently provided insights into the value of co-creation and the importance of honouring visiting as a Métis method in virtual environments.

Published: April 2021

O papel da mulher é fundamental para revelar novas territorialidades em uma região rural complexa social e ambientalmente como o Pantanal, onde a produção do espaço inicialmente aconteceu a partir da pecuária de corte, a qual, no final do século passado passou a ser compartilhado com a atividade turística. Nesse universo, a mulher pantaneira ocupa uma posição de destaque, mostrando-se integrada ao mundo do trabalho construído no país como um todo. Mesmo assim, em geral é pouco qualificada, mal remunerada e as atividades desenvolvidas representam a extensão do trabalho doméstico. Entretanto, é através do trabalho que o empoderamento ocorre, seja pela valorização da renda no âmbito familiar, ou pela afirmação identitária. Esse artigo discute os meandros do viver pantaneiro a partir da mulher, e tem como objetivo central é analisar o papel da mulher na produção do espaço turístico pantaneiro. O recorte espacial da pesquisa é a comunidade ribeirinha do Passo da Lontra, sub-região do Pantanal do Abobral, município de Corumbá (MS). A metodologia contou com revisão bibliográfica e trabalho de campo, com entrevistas estruturadas e semiestruturadas, analisadas à luz da geografia.Palavras-chave: Pantanal; Mulheres; Turismo; Trabalho.
Patrimônio, Cidade e o Papel do Desenho Urbano
Authors: Capestro Antonio
Published: April 2021

A conservação e valorização do Patrimônio Urbano constitui um dos desafios mais significativos dos últimos cinquenta anos, assumindo uma considerável importância tanto no sentido da preservarção e salvaguarda de valores compartilhados como na valorização da herança do passado enquanto recurso. Junto ao binômio clássico - e já bastante debatido - do projeto do patrimônio, o artigo propõe outro enfoque: a importância do patrimônio do projeto, uma vez que aquilo que se considera como Patrimônio é produto de um processo dinâmico que transfigura as permanências do passado para renovar sua contribuição no futuro. Ao não intervir sobre o patrimônio, estamos contradizendo sua própria essência. O artigo apresenta uma abordagem teórica que alimenta e é alimentada pela prática, focando na noção de patrimônio do projeto tanto na dimensão da pesquisa acadêmica quanto no desenho urbano e na intervenção sobre/no espaço, buscando um equilíbrio entre a preservação e uma constante evolução de usos e fruições que não dependem apenas de seu contexto geográfico e social, mas de fluxos mundiais, como o do turismo. Palavras-chave: Patrimônio; Cidade; Desenho Urbano.
The Matter at Hand: A Practice-Theoretical Model of Digital Gaming
Authors: Jaćević Milan
Published: April 2021

Investigations into the nature of the activity of gaming have been made difficult by virtue of the plurality of possible forms this activity may take. In this paper, I address this problem by examining (digital) gaming under the heading of practice theory, in an attempt to shed more light on the practical aspects of ludic literacy. Building on the theoretical and conceptual frameworks of Pierre Bourdieu, I present a general model of digital gaming as a form of situated human practice, followed by details of a case study, conducted in order to test and adjust the initial version of the model. Though further research with a greater population of players is needed in order to expand the scope of the model, the findings of the study lend credence to its validity as a conceptual framework for delineating and framing different practices generated by digital game artefacts.

Teacher cognition: A powerful phenomenon developing and governing habits of teaching
Authors: ÖZTÜRK Mustafa
Published: April 2021

Teaching has a complex feature being both a cognitive activity as well as a social behavior; thus, it is highly crucial to monitor how teachers develop and govern their habits and behavioral tendencies in the classroom. Teachers’ mental government has been the focus of educational research for a long time, because it is known to drive their actions. Considering teacher cognition as a powerful asset to develop and govern the habits of teaching, this paper adopts a conceptual review approach and presents a comprehensive and integrated literature review on teacher cognition along with its historical basis, key components, conceptual domains, origins, and driving forces. Building upon the empirical and theoretical literature compiled over a four-decade period, the paper presents a tripartite model regarding the conceptual domains of teacher cognition. As it is influenced by contextual circumstances surrounding teachers’ personal and professional lives, the concept of teacher cognition is revisited with regard to three origins and three driving forces. In this regard, the paper reconsiders teacher cognition in terms of the ways it is constructed and the ways it is oriented to action, and finally concludes with implications for teacher education.

Authors: YILMAZ Pelin
Published: April 2021

Masallar, duyguların ve düşüncelerin, dil aracılığıyla aktarıldığı sözlü anlatım türlerinden biridir. Masallarda, genellikle belirli sorunların çözümü ya da amaçların gerçekleştirilmesi için yolculuğa çıkan kahramanların maceraları anlatılır. Kırşehir sözlü kültürü içinde masallar önemli bir yer edinirler. Kırşehir’in sürekli göç alıp göç veren bir şehir olması, yöreden derlenen masalların içeriğine de yansır ve onların her bakımdan zenginleşmesinde etkin rol oynar.
Masalların hemen her konuda anlatılabilmesi, kolay üretilebilmesini ve zengin bir içeriğe sahip olmasını sağlar. Bu zenginliklerden biri de, masalların zengin dil içerikleridir. Bünyesinde taşıdıkları deyim ve atasözleri, halk deyişleri, yöresel kelimeler gibi dil özellikleriyle masallar, bir milletin zengin dil birikimini yansıtırlar.
Masalların ihtiva ettiği sözcükler, başlı başına bir araştırma ve inceleme konusu oluşturmaktadır. Halk masallarındaki kelimeler, halkın duygularını ve değerlerini yansıtırlar. Yansıtma işlemi ise genellikle bir kelimeye toplumca benimsenmiş olumlu ya da olumsuz anlamların eklenmesiyle yapılır. Bu çalışmada, Kırşehir’den derlenen Dev Anası adlı masaldaki kelimelerin uğradığı anlam değişmeleri, anlam iyileşmesi ve anlam kötüleşmesi bakımından incelenmiştir. İnceleme esnasında, masal metnindeki sözcüklerin, Türkçe Sözlük’teki birinci anlamı ile masal bağlamı içinde kazandığı yeni anlamı/anlamları karşılaştırılmıştır. Böylece masal anlatma geleneğinde anlam iyileşmesi ve kötüleşmesine uğrayan kelimeler tespit edilerek, irdelenmiş ve örnekleriyle açıklanmıştır.

Bir başka ifadeyle ebced hesabına tekabül eden sayıları esas alarak herhangi bir olayın tarihini bir veya birden çok kelime, mısra veya beyit hâlinde verecek şekilde harflerin her birinin sayı değerlerinin toplanması sonucunda meydana getirilen bir hesap sistemidir. Klasik Türk edebiyatı şairleri doğum, ölüm, evlenme, savaş, barış, sünnet, sakal bırakma, yangın, deprem, mansıb ve tayin durumları, zaferler, fetihler, mimarî yapıların tamiri veya inşası gibi hayatın her alanındaki konularda bu sanata başvurmuşlardır. Bu yönüyle tarih manzumeleri, Klasik Türk edebiyatına yöneltilen “halktan kopuk olma, gerçek hayattan tamamen soyutlanmış olma, sadece saray çevresinde gelişme imkânı bulma” iddialarının aksine gerçek hayattan izler taşımakta ve bahsettikleri konular bakımından yazıldığı dönemin sosyo-kültürel yapısını gözler önüne sermektedir.
Bu makalede, 19. yüzyıl şairlerinden olan ve genç yaşta hayatını kaybeden Recâî-zâde Ahmed Cevdet ve eserleri hakkında bilgi verilip Dîvânçe’sindeki tarih manzumelerinin transkripli metni hazırlanarak şekil ve muhteva yönünden incelemesi yapılmıştır.
Povos indígenas e as relações culturais, econômicas e políticas: reflexões sobre a interculturalidade crítica e a decolonialidade
Authors: Da Silva Matheus Moreira , Ribeiro José Pedro Machado , Nazareno Elias
Published: April 2021

Este artigo tem como objetivo problematizar e comparar interpretações e relatos voltados à interculturalidade crítica, decolonialidade e ecologia de saberes, os quais articulam elementos culturais, epistêmicos, materiais e simbólicos ligados ao papel das mudanças culturais e econômicas dos povos indígenas brasileiros, de diversas etnias, diante dos vários segmentos da sociedade nacional. Lançamos mão de olhares antropológicos, de abordagem hermenêutica, utilizando como opção política e metodológica a pedagogia decolonial, as reflexões próprias, estabelecendo debates significativos para identificar ideias e posturas (também políticas) sobre as imposições do Ocidente ante os povos indígenas. A proposta aqui estabelecida pretende reunir questões vinculadas aos sistemas políticos e comerciais das várias comunidades indígenas e os embates epistemológicos que constituem esses cenários, bem como analisar, em torno da interculturalidade, as mudanças históricas ocasionadas pelos vários segmentos da sociedade nacional.

Authors: R. Gomes Ana Maria , Corrêa C´élia Nunes , Miranda Shirley Aparecida de
Published: April 2021

Neste artigo, analisamos processos recentes de produção de materiais escritos entre os Xakriabá e os Pataxoop (MG), cujos produtos assumiram diferentes formatos, buscando trazer aspectos centrais que delineiam as características do conteúdo e da forma final do produto editorial. Ambos são povos indígenas que têm o português como língua materna. O caso dos Pataxoop ilustra uma reelaboração original da escrita em associação com outras formas expressivas, como o canto e o desenho. O caso dos Xakriabá revela o uso da escrita inserido em processo de elaboração sobre a história de luta, com um procedimento de autoria coletiva negociada no qual a memória ingressa num exercício cruzado de sentido acadêmico e político e com repercussões epistemológicas.

Las comunidades virtuales del quichua ecuatoriano: revalorizando la lengua en un espacio apropiado
Authors: Garcés Velásquez Luis Fernando
Published: April 2021

Las lenguas indígenas de América tienen una larga historia de subalternización que se mantiene hasta el día de hoy. Por esta razón, las Naciones Unidas declararon el 2019 como el Año Internacional de las Lenguas Indígenas, como un esfuerzo de revertir el proceso de pérdida de la diversidad lingüística del planeta. El quichua ecuatoriano es una lengua con presencia en varios países de la región. En Ecuador es la lengua indígena con mayor número de hablantes; sin embargo, hay evidencias de encontrarse en dramática situación de retroceso en cuanto a la trasmisión intergeneracional. En el contexto actual, los jóvenes quichua hablantes se apropian de recursos tecnológicos para la construcción de comunidades virtuales de defensa y difusión de la lengua y cultura quichua. En esta comunicación, se presenta una investigación de carácter exploratorio de dos comunidades virtuales en el Facebook: Kichwa Mashikuna y Kichwa Hatari NY. A partir de este acercamiento, se postula la necesidad de pensar la supervivencia lingüística de cara a la posibilidad de adaptación al contexto urbano y tecnológico. Y en este sentido, los jóvenes quichuas apuestan a “atravesar la modernidad”, antes que rodearla o negarla.

Published: April 2021

Objetivo: o objetivo deste estudo é estimar a prevalência de transmissão vertical da toxoplasmose baseado nos anticorpos IgG e IgM em uma população selecionada de crianças que nasceram em risco de toxoplasmose congênita. Metodologia: foi realizado um estudo observacional e transversal a partir da análise dos prontuários de crianças nascidas de uma gestação com risco de transmissão vertical (TV) de toxoplasmose que foram acompanhadas em um ambulatório público de infectologia pediátrica do Ceará em 2018. O risco de transmissão vertical de toxoplasmose foi confirmado se IgM do recém-nascido estava positivo. Resultado: das 51 crianças, cinco (9,80%) apresentaram confirmação sorológica de TV para toxoplasmose. Os testes sorológicos apresentaram valores mais elevados no grupo de TV. Estas crianças com transmissão vertical confirmada não apresentaram a tríade clássica e nasceram saudáveis em 60% dos casos. Conclusão: observou-se com este estudo que para cada caso confirmado, no pós-parto, de transmissão vertical de toxoplasmose, outros nove casos falso-positivos foram notificados, seguidos e investigados durante um ano. Recomenda-se, portanto, que melhores abordagens sorológicas maternas sejam implementadas durante o pré‑natal.

Approximate guaranteed estimates for matrices in linear regression problems with a small parameter
Authors: Nakonechnyi Oleksandr , Kudin Grygoriy , Zinko Petro , Zinko Taras
Published: April 2021

The problem of finding linear unbiased estimates of the
linear operator of unknown matrices — components of the observations vector, is investigated. It is assumed that the observation vector additively depends on a random vector with zero expected value, and the unknown correlation matrix belongs to a known bounded set. For the introduced class of linear estimates, necessary and sufficient conditions for the existence of solutions of operator equations that determine the unknown parameters of the vector estimate, are proved. The form of the guaranteed mean square error of the estimate is introduced on the sets of constraints of the problem parameters. The influence on the linear unbiased estimate of small perturbations of known rectangular matrices, which are the composites of the observations vector components, is also investigated. The analytical form is given through the parameters of the perturbed set of singularities for the introduced special operators that depend on a small parameter, which determine the corresponding operator equations, as well as their approximate solutions, in the first approximation of the small parameter method. A test example of solving the problem of finding a linear unbiased estimate under the condition of perturbation of both linearly independent and linearly dependent known observation matrices is presented.

Published: April 2021

This paper is dedicated to solving the problem of identifying and refining optimization indicators of operational efficiency and
updating of electronic systems of aircraft, which is a pertinent metrological task. An analysis of possible options for building a system of technical operation and updating of electronic systems of aircraft was conducted. The concept of the basic variant of construction of such a system is formulated. By means of defining classification features the basic variants of construction of a system of the technical operation and updating are selected. The notion of secondary and competing types of the basic variant of construction of such a system is defined. For this purpose, classification features have been introduced that characterize the properties of products of electronic systems: the place of updating the product, the place of fixing the product failure and the availability of means of operational control in the organization of maintenance.
Cellular automata models with complex valued transition functions
Authors: Makarenko Alexander
Published: April 2021

The new class of mathematical models for computation theory is considered — namely cellular automata (CA) with branching
complex-valued transition functions. The key point is possible multivaluedness of cell’s states with such transition functions. Different cases with complex-value transition functions had been considered. Dynamics CA on one branch and on different isolated branches are described. Also the case of transitions of states between branches is proposed. The case of continuous-valued CA and their finite-valued approximations are discussed. The problem of approximation of multivalued CA is stated.

Published: April 2021

Kebutuhan akan kapal Mini LNG (small LNG carrier) di Indonesia semakin meningkat seiring dengan meningkatnya kebutuhan pasokan LNG dari LNG field ke pulau-pulau di Indonesia bagian timur. Distribusi LNG ke pulau-pulau di Indonesia bagian timur kurang efektif bila menggunakan kapal LNG yang berukuran besar karena tidak adanya infrastruktur pipa gas untuk menyalurkan LNG dari terminal LNG di pelabuhan ke pengguna. Dengan kapal mini LNG maka pendistibusian LNG bisa menggunakan tangki-tangki LNG kecil yang nantinya akan dibawa oleh kendaraan darat setelah kapal bersandar di pelabuhan. Untuk mendesain sebuah kapal mini LNG diperlukan berbagai macam perhitungan yang tepat agar nantinya kapal yang dibangun akan memiliki performa yang baik dan efisien. Salah satunya yang harus dihitung adalah tahanan kapal dan EHP serta BHP untuk memprediksi daya mesin yang akan dipasang. Pada paper ini kajian difokuskan pada perhitungan tahanan kapal dan EHP serta BHP menggunakan metode simulasi numerik. Hasil dari paper ini untuk tahanan kapal desain 1 sebesar 101.01 kN dan untuk desain 2 sebesar 267.06 kN. Pada desain 1 untuk EHP sebesar 519.93 kW dan BHP sebesar 611.68 kW, sedangkan untuk desain 2 EHP sebesar 1373.87 kW dan BHP sebesar 1616.33 kW.

Proses uji kebocoran pada valve (katup) pada kapal merupakan tahapan yang penting dilakukan dan telah diatur oleh Biro Klasifikasi Indonesia (BKI) sebagai Klas yang mengacu pada The International Association of Classification Societies (IACS). Pipa dan alat fitting harus diuji pada tekanan hidrostatik tidak kurang dari 1,5 kali tekanan nominal. Padapenelitian ini, 4 buah gate valve yang diuji memiliki tekanan nominal dari pabrikan sebesar 10 bar, sehingga harus diuji hingga tekanan 15 bar. Katup telah diuji satu per satu dengan metode Hydrostatic Pressure Test yaitu menggunakan Test Pump. Dari hasil pengujian ditemukan kebocoran pada salah satu valve yaitu pada bagian disc. Rekomendasi yangdiberikan oleh pihak BKI untuk kebocoran tersebut adalah diperbaiki dengan cara menutupi kebocoran menggunakan bahan yang disarankan dari pabrikan pembuatan gate valve tersebut yaitu menggunakan lem besi tipe epoxy.
