Published: June 2021

Realizaremos uma breve análise teórica sobre o mundo do trabalho e a sua relação com as políticas capitalistas neoliberais que vêm tomando conta da nossa sociedade nas últimas décadas e que possuem fortes impactos na educação. Objetivamos entender o modo como essas relações afetam o campo educacional e a forma como a precarização e a desvalorização docente estão a favor do capitalismo. Discorreremos sobre os principais significados do trabalho e o modo como o sistema capitalista se apropria dele. Será possível criarmos um elo com o campo educacional brasileiro, que será discutido a partir da instauração da Base Nacional Comum Curricular (BNCC) que está a serviço da etapa neoliberal do capitalismo, algo comprovado a partir da utilização de expressões e ideias que são próprias do mundo empresarial, algo que não nos surpreende, visto que, principalmente a partir da década de 1990, os currículos implantados em nosso país foram elaborados com o intuito de atender aos anseios do Banco Mundial e de outros órgãos internacionais. Ao final, concluímos que o trabalho docente e o campo educacional estão, infelizmente, sendo forçados a se curvar perante o capitalismo, e para que possamos contornar tal situação, precisamos redefinir a nossa identidade enquanto professores.
Types of Love Between People: A Modern Perspective Using A Descriptive Assessment of Survey Research
Authors: Clingan Phillip D.
Published: June 2021

Love is the strong affection a person has towards the other person. Love can be between people of different gender, age, colour, social status, religion, or nationality. True love knows no boundaries, and that is why there exist different types of love. Most of the different types of love are derived from ancient Greek. The purpose of the study is to show why different people will have a different kind of love and why each of the love is important to the parties involved. The love between two people can take different forms, and two parties cannot have all the ten types of love discussed. The ten types of love discussed include love for parents, love for friends, agape love, love for animals, intimate love, selfish love, and unenduring love for friends, love for close friends, obsessive love towards people, and child love. Each of the love is unique in its way and is beneficial to both parties involved. The greatest of these types of love is agape love. A good example of agape love was portrayed in the life of Jesus in the Bible. He loved the human race unconditionally and gave all to save them from humanity. Also, child love and parent love are important types of love because they enhance strong bonds between parents and their children. Animal love can be obsessive because it will make a person become too close to animals in caring for them. However, it’s an important type of love because it creates a good relationship between human beings and animals. Animals tend to feel protected in the presence of human beings.
Modern Dönemde Ulema-Aydın Paradoksunun Oluşumu ve Etkileri

Makalenin temel fikirlerinden birisi, kendine has özgür ve değişime açık yapısıyla, diğer kültürlerdeki eşdeğerlerinden farkını ortaya koyan ulemanın, Osmanlı Devleti’nin başarısında büyük rolü olduğu öngörüsüdür. Devletin yüksek eğitim kurumları olan medreselerde eğitim faaliyetlerini yürüten bu ulema (ilmiye teşkilatı); ilmi birikimi, hayatı anlamlandırma çabaları, evrensel bakış açıları ile topluma yön verebilecek seviyedeydi. Makalede ele alınan temel problem, 18. ve 19. asırlara gelince ulemada görülen hızlı prestij düşüşünün manipüle edilip edilmediğini ortaya koymaktır. Makalenin önemsediği diğer bir mesele, 1839 Tanzimat Fermanı’nın ilanından sonra daha çok Batı kültürünün etkisi ile ulemanın karşısında konuşlanan aydınlardır. Bu aydınlar kısa sürede ulemanın Osmanlı Devleti’ndeki yerini almaya başlamış ve Batı kültürünün bir nevi temsilcileri pozisyonuna gelmişlerdir. Bu yeni reformistlerin, İslâm dünyasında Müslümanlığı muhafaza ederken Batılılaşmayı amaçlamaları yeni bir ikilem oluşturmuştur. Makalenin amacı, ortaya çıkan bu paradoksu tarihsel zemininde incelemek, toplum üzerinde nasıl bir etki ve algı oluşturduğunu ortaya çıkarmaktır. Araştırmada “tarihî araştırma yöntemi” kullanılmıştır. Bu yöntemle araştırmanın konusunu oluşturan dönem eleştirel bir gözle incelenip, doğru bir şekilde tahlil edilmeye gayret edilmiştir.

Published: June 2021

Clean and healthy living behavior (PHBS) in schools is an activity to empower students, teachers and the community of the school environment to want to adopt a healthy lifestyle, thus creating a healthy school. School age children are a critical age, because at that age a child is vulnerable to health problems. Students in elementary schools are the right targets to be objects of counseling about clean and healthy living behaviors (PHBS) with the aim of increasing students' knowledge and understanding of clean and healthy living behaviors. The activity was carried out on January 7, 2020 at the 25 state elementary schools in Ternate City. The results of counseling were an increase in knowledge from the results of the pre-test 35.5% and the post-test 65.5% about PHBS from 27 students with 10 questions.

Published: June 2021

The aim of the work was to develop an informative method for laboratory monitoring of osteoresorbent action during systemic administration of glucocorticoids in patients with ulcerative colitis. The study included 54 patients with ulcerative colitis aged 18 to 44 years: 35 (64,8%) men and 19 (35,2%) women. In patients of the clinical group before and after the first, second, third courses of glucocorticosteroids, as well as during the formation of steroid dependence, the concentration of the osteoresorption marker cathepsin K was determined simultaneously in the blood serum and gingival fluid by enzyme immunoassay. The concentration of the osteomarker was compared with the parameters of the densitometric density of the lumbar vertebrae L1-L4 during X-ray examination. It was found that with the systemic use of glucocorticoids in patients with ulcerative colitis, the concentration of cathepsin K in the gingival fluid increased earlier than in the blood serum. It was found that with an increase in the concentration of cathepsin K in the gingival fluid of more than 2,6 pmol/l in conditions of systemic administration of glucocorticosteroids, the risk of osteoporosis increased with a diagnostic sensitivity of 81,8% and a specificity of 74,4% (p=0,0001).The diagnostic accuracy was 78,1%. With an increase in the concentration of cathepsin K in the gingival fluid above the differential separation level (2,6 pmol/l), the risk of developing osteoporosis increased 3,2 times (p= 0,0001). The study developed a methodological and informational algorithm has been developed for the non-invasive control of steroidal osteoporosis in patients with ulcerative colitis with systemic use of glucocorticoids by assessing the concentration of cathepsin K in the gingival fluid.

Tularemia is an especially dangerous infection caused by the gram-negative bacterium Francisella tularensis. It belongs to natural focal infections, and therefore is under continuous control by quarantine services. When carrying out their activities they use a whole range of diagnostic tools. The objective of this research is to develop an enzyme immunoassay based on highly specific monoclonal antibodies and immunomagnetic particles for monitoring the tularemia pathogen. To produce hybridomas mice were immunized with cells of the vaccine strain F. tularensis subsp. holarctica 15 NIIEG. After cell fusion hybridomas were selected by a solid-phase enzyme immunoassay (ELISA) using lipopolysaccharide (LPS) of the tularemia microbe. As a result, two hybridomas, 1C2 and 3F5, were produced. MABs of the hybridomas were obtained by using BALB / c mice. The MABs were purified by sepharose A affinity chromatography and used for conjugation with magnetic particles, and for biotinylation followed by matching a pair for ELISA. The pair of IMPs and MABs 3F5 as well as biotinylated FB11-x MABs was the best in detecting tularemia cells. The use of this MAB pair in ELISA allowed the identification of 105 microbial cells/ml in a 4 ml sample and 5×103 microbial cells/ml in a 45ml sample. Interaction with F. tularensis subsp. novicida Utah112 cells was absent.

Overactive JAK pathway signaling is a hallmark of immune diseases and critically affects on inflammation and coagulation. A number of mutations in the JAK2 gene act as driving forces of myeloproliferative neoplasms (MPN), the pathogenesis of certain variants of acute leukemia, a number of solid malignancies and cardiovascular diseases. Assays for quantifying JAK2 mRNA in circulating blood cells can be used as a marker associated with the activity of this enzyme. Development of an original method for detecting JAK2 mRNA in venous blood and assessment of the possible diagnostic value in chronic oncohematological diseases. The development of an RT-PCR method for determining the expression of the JAK2 gene mRNA in venous blood samples was carried out in accordance with the MIQE requirements. Primers and TaqMan probes were designed using the Primer3 program, taking into account the possibility of excluding subsequent DNase treatment. The stability of the investigated mRNA was assessed in vacutainers with different anticoagulants and depending on the storage time of the samples. The study of the expression of JAK2 mRNA in blood leukocytes of 41 patients with B-CLL, 16 patients with CML, 12 patients with multiple myeloma and 39 donors using the developed “real-time” PCR method. The study revealed a decrease in the level of JAK2 mRNA in venous blood samples in patients with primary CLL, but not with CML or with multiple myeloma. The level of the marker in the majority of patients with CLL after the start of therapy returned to the range typical for healthy people. It has been shown that the values of the relative expression of JAK2 mRNA are most stable in the range of 2 - 7 hours after taking blood in a vacutainer with EDTA. An original RT-PCR method was developed for the quantitative determination of JAK2 mRNA in venous blood samples, which meets the requirements of the MIQE system. Determination of JAK2 mRNA can be useful for clarifying the pathogenesis features of certain diseases involving impaired Janus kinase activity and can become a promising marker for prognosis and assessment of the effectiveness of therapy.

O objetivo do presente artigo é apresentar a metodologia de ensino de filosofia proposta por Silvio Gallo, a oficina de conceitos. Essa metodologia se difere das outras porque realiza, a partir da pedagogia do conceito proposta por Deleuze, a rejeição de qualquer método que se pauteie unicamente na recognição. Para isso faremos uma breve análise a crítica de Silvio Gallo a partir dos moldes do ensino de filosofia nas escolas brasileiras. Após essa análise e diagnóstico, apresentaremos a ideia da filosofia como criação de conceitos e suas consequências para a relação entre o ensino e a aprendizagem, e o papel do professor na aula de filosofia. Em seguida, apresentaremos os quatro passos para a aula de filosofia proposto por Silvio Gallo. Por fim, concluiremos que tal proposta permite uma experiência filosófica que torna a filosofia um fim em si mesma e não apenas um meio para a prática cidadã.

Assessing the contribution of the ENSO and MJO to Australian dust activity based on satellite- and ground-based observations
Authors: Yu Yan , Ginoux Paul
Published: June 2021

Abstract. Despite Australian dust's critical role in the regional climate and
surrounding marine ecosystems, the controlling factors of the spatiotemporal
variations of Australian dust are not fully understood. Here we assess the
connections between observed spatiotemporal variations of Australian dust
with key modes of large-scale climate variability, namely the El
Niño–Southern Oscillation (ENSO) and Madden–Julian Oscillation
(MJO). Multiple dust observations from the Aerosol Robotic Network (AERONET),
weather stations, and satellite instruments, namely the Moderate Resolution
Imaging Spectroradiometer (MODIS) and Multi-angle Imaging SpectroRadiometer
(MISR), are examined. The assessed multiple dust observations consistently
identify the natural and agricultural dust hotspots in Australia, including
the Lake Eyre basin, Lake Torrens basin, Lake Frome basin, Simpson Desert,
Barwon–Darling basin, Riverina, Barkly Tableland, and the lee side of the Great
Dividing Range, as well as a country-wide, austral spring-to-summer peak in dust
activity. Our regression analysis of observed dust optical depth (DOD) upon an
ocean Niño index confirms previous model-based findings on the enhanced
dust activity in southern and eastern Australia during the subsequent austral
spring and summer dust season following the strengthening of austral
wintertime El Niño. Our analysis further indicates the modulation of the
ENSO–dust relationship with the MJO phases. During sequential MJO phases, the
dust-active center moves from west to east, associated with the eastward
propagation of MJO, with the maximum enhancement in dust activity at about 120,
130, and 140∘ E, corresponding to MJO phases 1–2, 3–4, and 5–6,
respectively. MJO phases 3–6 are favorable for enhanced ENSO modulation of
dust activity, especially the occurrence of extreme dust events, in
southeastern Australia, currently hypothesized to be attributed to the
interaction between MJO-induced anomalies in convection and wind and
ENSO-induced anomalies in soil moisture and vegetation.

Abstract. Recent increases in boreal forest burned area, which have
been linked with climate warming, highlight the need to better understand
the composition of wildfire emissions and their atmospheric impacts. Here we
quantified emission factors for CO and CH4 from a massive regional fire
complex in interior Alaska during the summer of 2015 using continuous
high-resolution trace gas observations from the Carbon in Arctic Reservoirs
Vulnerability Experiment (CRV) tower in Fox, Alaska. Averaged over the 2015
fire season, the mean CO / CO2 emission ratio was 0.142 ± 0.051, and
the mean CO emission factor was 127 ± 40 g kg−1 dry biomass
burned. The CO / CO2 emission ratio was about 39 % higher than the mean
of previous estimates derived from aircraft sampling of wildfires from
boreal North America. The mean CH4 / CO2 emission ratio was 0.010 ± 0.004, and the CH4 emission factor was 5.3 ± 1.8 g kg−1 dry biomass burned, which are consistent with the mean of previous
reports. CO and CH4 emission ratios varied in synchrony, with higher
CH4 emission factors observed during periods with lower modified
combustion efficiency (MCE). By coupling a fire emissions inventory with an
atmospheric model, we identified at least 34 individual fires that
contributed to trace gas variations measured at the CRV tower, representing
a sample size that is nearly the same as the total number of boreal fires
measured in all previous field campaigns. The model also indicated that
typical mean transit times between trace gas emission within a fire
perimeter and tower measurement were 1–3 d, indicating that the time
series sampled combustion across day and night burning phases. The high CO
emission ratio estimates reported here provide evidence for a prominent role
of smoldering combustion and illustrate the importance of continuously
sampling fires across time-varying environmental conditions that are
representative of a fire season.
Evaluating cloud liquid detection using cloud radar Doppler spectra in a pre-trained artificial neural network against Cloudnet liquid detection

Published: June 2021

Abstract. Detection of liquid-containing cloud layers in thick mixed-phase clouds or multi-layer cloud situations from ground-basedremote sensing instruments still pose observational challenges yet improvements are crucial since the existence of multi-layerliquid layers in mixed-phase cloud situations inﬂuences cloud radiative effects, cloud life time, and precipitation formationprocesses. Hydrometeor target classiﬁcations such as Cloudnet that require a lidar signal for the classiﬁcation of liquid arelimited to the maximum height of lidar signal penetration and thus often lead to underestimations of liquid-containing cloudlayers. Here we evaluate the Cloudnet liquid detection against the approach of Luke et al. (2010) which extracts morphologicalfeatures in cloud-penetrating cloud radar Doppler spectra measurements in a artiﬁcial neural network (ANN) approach toclassify liquid beyond full lidar signal attenuation based on the simulation of the two lidar parameters particle backscattercoefﬁcient and particle depolarization ratio. We show that the ANN of Luke et al. (2010) which was trained in Arctic conditionscan successfully be applied to observations in the mid-latitudes obtained during the seven-week long ACCEPT ﬁeld experimentin Cabauw, the Netherlands, 2014. In a sensitivity study covering the whole duration of the ACCEPT campaign, different liquid-detectionthresholds for ANN-predicted lidar variables are applied and evaluated against the Cloudnet target classiﬁcation.Independent validation of the liquid mask from the standard Cloudnet target classiﬁcation against the ANN-based techniqueis realized by comparisons to observations of microwave radiometer liquid water path, ceilometer liquid-layer base altitude,and radiosonde relative humidity. Four conclusions were drawn from the investigation: First, it was found that the thresholdselection criteria of liquid-related lidar backscatter and depolarization alone control the liquid detection considerably. Second,nevertheless, all threshold values used in the ANN-framework were found to outperform the Cloudnet target classiﬁcation fordeep or multi-layer cloud situations where the lidar signal is fully attenuated within low liquid layers and the cloud reﬂectivityin higher cloud layers was sufﬁciently high to be detectable by the cloud radar. Third, in convective situations for whichlidar data is available and for which the imprint of cloud microphysics on the radar Doppler spectrum is decreased, Cloudnetoutperforms the ANN retrieval. Fourth, in high-level clouds both approaches (Cloudnet and the ANN technique), are limited.
Modelling long-term alluvial peatland dynamics in temperate river floodplains
Authors: Swinnen Ward , Broothaerts Nils , Verstraeten Gert
Published: June 2021

Abstract. Peat growth is a frequent phenomenon in European river valleys. The presence of peat in the floodplain stratigraphy makes them hotspots of carbon storage. The long-term dynamics of alluvial peatlands are complex due to interactions between the peat and the local river network, and as a result, alluvial peatland development in relation to both regional and local conditions is not well understood. In this study, a new modelling framework is presented to simulate long-term peatland development in river floodplains by coupling a river basin hydrology model (STREAM) with a local peat growth model (modified version of Digibog). The model is applied to two lowland rivers in northern Belgium, located in the European loess (Dijle river) and sand (Grote Nete river) belts. Parameter sensitivity analysis and scenario analysis are used to study the relative importance of internal processes and environmental conditions on peatland development. The simulation results demonstrate that the peat thickness is largely determined by the spacing and mobility of the local river channel(s) rather than by channel characteristics or peat properties. In contrast, changes in regional conditions such as climate and land cover across the upstream river basin showed to influence the river hydrograph, but have a limited effect on peat growth. These results demonstrate that alluvial peatland development is strongly determined by the geomorphic boundary conditions set by the river network and as such models must account for river channel dynamics to adequately simulate peatland development trajectories in valley environments.

Abstract. Atmospheric inversions are used to derive constraints on the net sources and sinks of CO2 and other stable atmospheric tracers from their observed concentrations. The resolution and accuracy that the fluxes can be estimated with depends, among other factors, on the quality and density of the observational coverage, on the precision and accuracy of the transport model used by the inversion to relate fluxes to observations, and on the adaptation of the statistical approach to the problem studied. In recent years, there has been an increasing demand from stakeholders for inversions at higher spatial resolution (country scale), in particular in the framework of the Paris agreement. This step up in resolution is in theory enabled by the growing availability of observations from surface in situ networks (such as ICOS in Europe) and from remote sensing products (OCO-2, GOSAT-2). The increase in the resolution of inversions is also a necessary step to provide efficient feedback to the bottom-up modeling community (vegetation models, fossil fuel emission inventories, etc.). However, it calls for new developments in the inverse models: diversification of the inversion approaches, shift from global to regional inversions, and improvement in the computational efficiency. In this context, we developed LUMIA, the Lund University Modular Inversion Algorithm. LUMIA is a Python library for inverse modeling built around the central idea of modularity: it aims to be a platform that enables users to construct and experiment with new inverse modeling setups while remaining easy to use and maintain. It is in particular designed to be transport-model-agnostic, which should facilitate isolating the transport model errors from those introduced by the inversion setup itself. We have constructed a first regional inversion setup using the LUMIA framework to conduct regional CO2 inversions in Europe using in situ data from surface and tall-tower observation sites. The inversions rely on a new offline coupling between the regional high-resolution FLEXPART Lagrangian particle dispersion model and the global coarse-resolution TM5 transport model. This test setup is intended both as a demonstration and as a reference for comparison with future LUMIA developments. The aims of this paper are to present the LUMIA framework (motivations for building it, development principles and future prospects) and to describe and test this first implementation of regional CO2 inversions in LUMIA.

Abstract. Ammonia is one of the most widespread foraminiferal genera
worldwide. Three phylotypes (Ammonia sp. T1, T2 and T6), commonly encountered in
the northeast Atlantic, are usually associated with the morphospecies
Ammonia tepida. The biogeographic distribution of these three types was previously
investigated in coastal environments around Great Britain based on genetic
assignations. A new method was recently developed to recognize these three
phylotypes based on morphological criteria (i.e. pore size and suture
elevation on spiral side), avoiding the need to use molecular analyses to
identify them. The results presented here allow us to validate the
consistency of the morphometric determination method but also to define more
precisely the pore size variability of each of the three phylotypes, which
is a main criterion for their recognition. Moreover, these results, combined
with earlier molecular and morphological data, enable us to refine the
biogeographic distribution previously established by genetic analyses alone.
The biogeographical distribution pattern presented here supports the
putatively invasive character of Ammonia sp. T6, by suggesting that this phylotype
is currently spreading out over large areas and is supplanting
autochthonous phylotypes (T1 and T2) along the coastlines of the British
Isles and northern France. In fact, only the southwest coast of England and Ireland and the northwest coast of France have not been colonized by
Ammonia sp. T6 yet. Our results also suggest that within the areas colonized by
phylotype T6, T2 may find refuges in the inner parts of estuaries. We
further suggest that the absence of Ammonia sp. T6 in the western part of the
English Channel may be explained by the general surface current circulation
pattern, which impedes further expansion. The high reliability of the
determination method of phylotypes T1, T2 and T6 based on morphology also
allows us to quickly generate large datasets for sub-recent and fossil material.
This new method will make it possible to gain an understanding of the
ecological differences between the three phylotypes and of the historical
changes in their distribution patterns (for example due to changing
anthropogenic factors). Finally, it will allow us to confirm or invalidate
the putative invasive character of phylotype T6.
Antarctic snow-covered sea ice topography derivation from TanDEM-X using polarimetric SAR interferometry

Abstract. Single-pass interferometric synthetic aperture radar (InSAR) enables the possibility for sea ice topographic retrieval despite the inherent dynamics of sea ice. InSAR digital elevation models (DEM) are measuring the radar scattering centre height. The height bias induced by the penetration of electromagnetic waves into snow and ice leads to inaccuracies of the InSAR DEM, especially for multi-year sea ice with snow 5 cover. In this study, an elevation difference between the satellite-measured InSAR DEM and the airborne-measured optical DEM is observed from a coordinated campaign over the western Weddell Sea in Antarctica. The objective is to correct the penetration bias and generate a precise sea ice topographic map from the single-pass InSAR data. With the potential of retrieving sea ice geophysical information by the polarimetric-interferometry (Pol-InSAR) technique, a two-layer plus volume model is proposed to represent the sea ice vertical structure and its scattering mechanisms. Furthermore, a simplified version of the model is derived, to allow its inversion with limited a priori knowledge, which is then applied to a topographic retrieval scheme. The model-retrieved performance is validated with the optical DEM of the sea ice topography, showing an excellent performance with root-mean-square error as low as 0.22 m. The experiments are performed across four polarizations: HH, VV, Pauli-1 (HH+VV), and Pauli-2 (HH-VV), indicating the polarization-independent volume scattering property of the sea ice in the investigated co-polarized data.
Some effects of flow expansion on the aerodynamics of horizontal-axis wind turbines
Authors: Wood David , Limacher Eric
Published: June 2021

Abstract. Upwind of an energy-extracting horizontal-axis wind turbine, the flow expands as it approaches the rotor, and the expansion continues in the vorticity-bearing wake behind the rotor. The upwind expansion has long been known to influence the axial momentum equation through the axial component of the pressure, although the extent of the influence has not been quantified. Starting with the impulse analysis of Limacher & Wood (2020), but making no further use of impulse techniques, we demonstrate that the expansion redistributes momentum from the external flow to the wake and derive its exact expression when the rotor is circumferentially uniform. This expression, which depends on the radial velocity and the axial induction factor, is added to the thrust equation containing the pressure on the back of the disk. Removing the pressure to obtain a practically useful equation shows the axial induction in the far-wake is twice the value at the rotor only at high tip speed ratio and only if the relationship between vortex pitch and axial induction in non-expanding flow carries over to the expanding case. At high tip speed ratio, we assume that the expanding wake approaches the "Joukowsky'' model of a hub vortex on the axis of rotation and tip vortices originating from each blade. The additional assumption that the helical tip vortices have constant pitch, allows a semi-analytic treatment of their effect on the rotor flow. Expansion modifies the relation between the pitch and induced axial velocity so that the far-wake area and induction are significantly less than twice the values at the rotor. There is a moderate decrease – about 6 % – in the power production and a similar size error occurs in the familiar axial momentum equation involving the axial velocity.

Indonesia merupakan salah satu negara kepulauan yang terdiri dari beberapa pulau besar dan beribu-ribu pulau kecil. Menurut data terbaru, total sebanyak 17.504 pulau ada di perairan Indonesia dengan 6.000 di antaranya merupakan pulau berpenghuni. Pulau-pulau kecil dengan criteria luas yang kurang dari 2.000 m2 tidak memiliki sumber air bersih yang cukup atau bahkan tidak ada sama sekali. Banyak solusi yang sudah dikembangkan terkait krisis air bersih ini salah satunya menyediakan alat penyulingan air laut menjadi air bersih atau biasa disebut sistem desalinasi oleh pemerintah setempat. Namun itu tidak berjalan efektif dikarenakan biaya perawatan alat tersebut cukup mahal dan iuran yang dibebankan pada masyarakat untuk biaya perawatan tidak sebanding dengan pendapatan penduduk sekitar. Pada penelitian ini dirancang suatu transportasi air yang mampu mendistribusikan mesin atau sistem desalinasi portabel beserta kebutuhan logistik lainnya dari pulau ke pulau. Dikarenakan tidak semua pulau memiliki dermaga dan fasilitas bongkar muat yang memadai, maka peneliti berinisiatif untuk merancang sebuah Kapal Amphibi berjenis Hovercraft untuk mempermudah proses distribusi hingga bongkar muat di daratan. Proses perancangan dilakukan menggunakan metode sister ship dengan mempertimbangkan ukuran benda yang akan diangkut sehingga ditentukan Panjang = 13,2 m, Lebar = 6,7 m, material Aluminium, dengan total berat = 19 ton, Kecepatan = 50 knot, dan desain mengacu pada Hovercraft tipe pengangkut. Berdasarkan data-data tersebut didapatkan kapasitas total daya angkat sebesar 1909,44 HP dan daya dorong sebesar 695, 61 HP.
