Implementation of Competency-based Language Teaching in Speaking Skills Instruction
Authors: Derseh Gebisa Ayana
Published: December 2023

Competency-Based Language Teaching (CBLT) improves quality of learning and students’ result when implemented properly. Consequently, it is implemented at primary schools’ language instruction. This study aimed to investigate the implementation of Competency-Based Language Teaching in English speaking skills instruction. The study adopted a mixed methods approach and descriptive survey design. A simple random sampling technique was used to select 97 Grade Four English teacher respondents. Data were collected using a questionnaire, observation, and interviews. While the qualitative data were analyzed verbatim, the quantitative data were analyzed with descriptive and inferential statistics. The result showed that fewer activities useful for competency development in speaking skills were used; learners were provided insufficient activities leading to mastery of competency, teachers’ use of multiple ways of teaching speaking in the CBLT context was limited and implementation of the CBLT varies among districts. The study recommends that teachers give students chances to practice speaking skills using sufficient activities leading to competency, and are required to use multiple ways of teaching speaking to meet mastery of competency.

Logarithmic coefficients for a class of analytic functions defined by subordination
Authors: Nistor-Șerban A. , Raducanu D.
Published: December 2023

In this paper we consider a class of functions Mα(φ) defined by subordination, consisting of functions f ∈ A satisfying the condition (1 −α) zf′(z)/ f(z) + α (1 + zf′′(z)/ f′(z) )≺ φ(z), z ∈ U. In the study of univalent functions, estimates on the Taylor coefficients are usually given. Another significant problem deals with the estimates of logarithmic coefficients. For the class S of univalent functions no sharp bounds for the modulus of the individual logarithmic coefficients are known if n ≥ 3. For different subclasses of S the results are not better and in most cases only th e first three initial coefficients of log f(z)/z are considered. For the class Mα(φ) we obtain upper bounds for the logarithmic coefficients γn, n ∈ {1, 2, 3} and also for Γn, n ∈ {1, 2, 3}, the logarithmic coefficients of the inverse of Mα(φ). Connections with previous known results are pointed out.

Authors: Al-Lami Narjis A.R. , Al-joofy Ikbal K.
Published: December 2023

Background: Chronic gastritis (CG) is histopathological entity characterized by chronic inflammation of the stomach that mostly caused by Helicobacter pylori, development ofinflammation in gastric mucosa result in release of pro- and anti- inflammatory cytokines .This study aimed to shed light on the role of cytokines (IFN-γ, IL-8, IL-4, IL-10, and GM-CSF) in thedevelopment and prognosis of CG among Iraqi patients.Patients and methods: 100 Iraqi patients with CG (61 male and 39 female) with age range (10-79) year, were involved in this stady while attending Specialist Hospital of Disease of Liver and Gastrointestinal System at Baghdad Medical City from Nov. 2007 to Apr. 2008. Patients divided according to histological diagnosis into three groups : 66 with active CG, 21 with Superficial CG and 13 with Inactive CG . All Patients were investigated for infection with H. pylori by histological \examination and for quantitative estimation of serum anti H. pylori (IgG) by Enzyme Linked Immunosorbent Assay (ELISA), and Amplified Sensitivity Immuno Assay (EASIA) technique to measure the level of cytokines (IFN-γ, IL-8, IL-4, IL-10, and GM-CSF) for both patients and healthy control groups.Results: Incidence of H. pylori is (66٪) among all patients, highly significant increased (p<0.01) in serum level of anti H. pylori in patient groups: Active CG, Superficial CG and Inactive CGrespectively and significant increased (p<0.01) trend of IFN-γ, IL-8, IL-4, IL-10, and GM-CSF in all patient groups as compared with healthy control.Conclusions: High frequency of H. pylori in patient reflect the important role of H. pylori in etiopathogenesis of CG. Increased serum level of cytokines (IFN-γ, IL-8, IL-4, IL-10, and GM-CSF)propaply play crucial role in driving inflammatory process and promoting gastric mucosa destruction in CG, regulation of these cytokines is consider as an important therapeutic goal.

Published: December 2023

Background: Green tea Camellia sinensis is non fermented tea. The tea is an infusion of flavorful leaves that has been consumed for centuries as a beverage and is valued for its medicinal properties. Over the last few decades green tea has been subjected to many scientific and medical studies to determine the extent of its long-purported health benefits, with some evidence suggesting regular green tea drinkers may have lower chances of heart disease and developing certain types of cancer. Green tea has also been claimed useful for weight loss management.Methods: Three doses of the hot water extract were used (19.2, 38.4 and 57.6 mg/kg) to investigate micronucleus formation and phagocytic index. Mice were divided into two groups. Group one; control and group two; mice were administered with three doses of the green tea extract orally as a single dose (0.1 ml) per day for 7 days. Then the mice were sacrificed in day 8 for immunological and cytogenetic assessments.Results: Results revealed that the first and third doses of green tea hot water extract were significantly effective in enhancing the values of phagocytic index and reducing micronucleusformation.Conclusions: Hot water may be a good solvent to extract active component from Camellia sinensis especially catechin, polyphenols, polysaccharides, flavonoids and vitamins. The high dose of hot water extracts of Camellia sinensis showed an excellent enhancing effects on the function of immune system of mice, moreover, reduction in micronucleus formation was recorded at such dose.
Finite-element simulation of residual stresses induced by laser shock peening in TC4 samples structurally similar to a turbine blade
Authors: Kostina Anastasiia , Zhelnin Maxim , Swaroop Sathya , Vedernikova Alena , Bartolomei Mariia
Published: December 2023

This study is devoted to the investigation of residual stresses distribution (RSD) in a TC4 sample treated with laser shock peening. The study placed special emphasis on analyzing the RSD at the part of the samples structurally similar to a turbine blade, which is more frequently subjected to damage during service according to the aircraft statistics. Results of simulation showed that low power density of 1.11 GWt/cm2 could not induce compressive residual stress on the surface of a treated object. Furthermore, increasing the overlapping of laser spots does not improve the situation and still fail to induce surface compressive residual stress at a laser intensity of 1.11 GWt/cm2. The compressive stresses occur only with the rise in power density. Reducing the spot size from 3 mm to 1 mm for the power density of 10 GWt/cm2 results in a 20% increase in the magnitude of compressive residual stress in the area of interest. Moreover, applying 35% overlapping further enhances this value. In addition to increasing the magnitude of residual stress, this approach also leads to a more homogeneous RSD of the treated material.
Effect of Granular Waste Compact Disc on Bond Strength between Steel Bars and Surrounding Concrete
Authors: Mawlood Barzan , Khaleel Sanaa , Mohammad Ahmed
Published: December 2023

In recent decades, researchers have tried to use waste materials as a partial or complete replacement of the gravel ingredients of concrete to reduce environmental impact. One of these materials is electronic waste. The problem of this disposal material, particularly outdated CDs and DVDs, has turned out to be serious. In this study, 36 pull-out cylindrical shape test specimens were used to conduct an ASTM C234-91A-compliant pull-out test to measure the bonding behavior and strength between three sizes of steel bars and concrete with different embedded lengths, including waste disc shreds (CD and DVD) as a partial substitute for fine aggregate. Four groups of modified concrete specimens with different percentages of disc shreds as partial replacements for sand were prepared. The ratio of cement:sand+disc:coarse aggregate:water was 1:2:2.5:0.4. The disc shreds were utilized to substitute partially for fine aggregate in four different weight percentages: 0%, 4%, 8%, and 12%; nevertheless, the cement-to-sand ratio was consistently 2. Results demonstrated that the bond strength is considerably influenced by the bar diameter and the disc shreds (CDs and DVDs) used as a partial replacement for fine aggregate. The bond strength behavior of the modified concrete with disc fibers is comparable with that of traditional concrete. The ACI-318 Code for the bond strength of ordinary Portland cement concrete was modified to calculate the bond strength of this new kind of disc concrete.

Published: December 2023

In several industrial applications, plastic, composites and ceramics replace a number of metallic structures such as copper, aluminum and steel. Most recently installed piping water and gas systems in the world are made of thermoplastic due to its advantages, for example, low cost, ease of fabrication and corrosion resistance. In this work, the chosen material is chlorinated polyvinyl chloride (CPVC); the best one used to transport cold and hot water beside simplicity of installation. Notwithstanding, the pipes in service are submitted to different loads, related to environmental, thermal and mechanical effects which procure to mechanisms of degradation. The aim of this article is to assess the effect of the defect on CPVC pipes, through a study of the defect criticality in the form of semi-elliptical, then the ability to predict defected pipes residual life. Therefore unexpected and sudden failure caused by pipes accelerated damage. Therefore, we performed burst tests on both pre-damaged CPVC pipes and virgin ones. To lead our work in this paper, interested in the damage modeling and the failure analysis of CPVC pipes, we adapted the model of unified theory static damage, originally developed in fatigue. We used burst pressure tests to identify the limits of three damage progression phases and, in turn, to calculate the critical life fraction at which these flaws become harmful. Furthermore, we identify the critical depth for the studied defect. These results and techniques enable industrialist s to anticipate this structures service life under these conditions after that set up a robust system of maintenance to ensure a reliable and safe functioning of the structure.

Authors: Mahmoud Ahmed , Nasser Moaz , Mostafa Tarek , Khater Ahmed
Published: December 2023

There are a few kinds of research about box section Reinforced Concrete (RC) beams under the effect of combined shear and torsional stresses. In the present research, the concept of adding external strengthening, in the transverse direction, is adopted. The paper focuses on using Glass Fiber Reinforced Polymer GFRP ropes as near-surface mount stirrups. Nine box-section concrete specimens were decanted and tested. Three variables are adopted, (1) GFRP stirrups diameter, (2) GFRP stirrups inclination, and (3) GFRP stirrups spacing. The experimental results showed considerable enhancement in the shear capacity of the strengthened beams by 8 to 56% depending on the effectiveness of the studied parameters. Ductility and toughness were improved when more intensive strengthening schemes were adopted. The shear capacity of all tested beams based on Egyptian code ECP 208–2019 is calculated and compared with that from American code ACI 440–2019 and Canadian code CSA-A23.3-04. The shear capacity from both Egyptian and American codes compared with experimental loads. The analytical results are conservative in some cases and unconservative in others while the analytical results in general are conservative. The Canadian code CSA-A23.3-04 is unconservative compared to the experimental results for the range of the studied parameters and specimens.

Published: December 2023

Bu çalışmada, XVII. yüzyıl klasik Türk edebiyatı şairlerinden Pehlevân-zâde nâmıyla anılan Bekâyî ve şiirleri konu edilmektedir. Türkçe kaleme alınan şair biyografileri konulu eserler arasında Bekâyî’nin biyografisinin madde başı esasıyla yer aldığı tek kaynak, XVII. yüzyılda yazılan şuara tezkirelerinden Tezkire-i Rızâ’dır. Buna rağmen Bekâyî’nin, biyografisinin söz konusu tezkirenin eski harflerle yapılan baskısında, yurtiçi kütüphanelerdeki yazmalarının ise tümünde bulunmayışından dolayı gözden kaçmış bir şair olduğu anlaşılmaktadır. Şiirlerini günümüze ulaştıran ve tespitine olanak sağlayan yazmanın tek nüshası, Selimiye Yazma Eser Kütüphanesi’nde, Ahmed Bâdî koleksiyonu içerisinde 2208 numarayla kayıtlıdır. Değişik yerlerine düşülen kayıtlardan XVIII. yüzyılda derlendiği öğrenilen yazma içerisinde Bekâyî’nin şiirlerinden başka Figânî, Şeyhülislâm Yahyâ ve Sâbit’in Dîvân’larından seçilmiş şiirler bulunmaktadır. İçeriği yönüyle yazma, adı geçen şairlerin şiirlerinin bütününü ihtiva eden yapıda olmayıp daha çok bu şairlerin Dîvân’larından yapılmış bir şiir seçkisi görünümü arz etmektedir. Bekâyî’nin şiirlerinin sonunda yer verilen itmam kaydında Dîvân ifadesi bulunan yazmada, değişik nazım şekilleriyle kaleme alınan 31 parça şiiri kayıtlıdır. Diğer taraftan mevcut şiirler, Bekâyî’nin biyografisinin bazı yönlerinin aydınlatılmasına da kaynaklık eder. Şairin kendi şiirlerinde rastlanan söz konusu ayrıntılar, biyografisinin yegâne kaynağı olan Tezkire-i Rızâ ile birçok açıdan mutabıktır. Bekâyî’nin mevcut şiirleri arasında özellikle perestişnâme başlığını taşıyan iki manzumesi; manzum mektup, şehir methiyesi, şairnâme ve kâtipler hakkında yazılmış hiciv gibi farklı türden özellikleri bünyesinde barındıran şiirler olması yönünden dikkat çekmekte ve Türk edebiyatında kaleme alınmış bu türden manzumelerin bilinmeyen örnekleri arasında yer almaktadır. Çalışmada öncelikle Bekâyî’nin şiirlerini günümüze ulaştıran yazma hakkında bilgi verilmiş, Tezkire-i Rızâ ve mevcut şiirlerine yansıyan bilgilerden hareketle biyografisi ve edebî kişiliğine dair dikkat çeken ayrıntılar ortaya konulmaya çalışılmış ve şiirlerinin çeviriyazılı metni sunulmuştur. Böylelikle Türk edebiyatı tarihinde adı gölgede kalmış bir şair ve onun daha önce herhangi bir incelemeye konu edilmeyen belli miktarda şiirinin gün yüzüne çıkarılmasının amaçlandığı makalenin, Bekâyî ve şiirleri hakkında yapılacak başka çalışmalar için temel teşkil etmesi hedeflenmektedir.
Development of a Hybrid Technological Scheme for the Treatment of Anaerobically Fermented Sludge (Digestat) of Wastewater of the Food Industry
Authors: Shevchenko Andrii , Miasoiedov Oleksii , Shevchenko Tamara
Published: December 2023

The issue of dewatering and disposal of sewage sludge is one of the most urgent due to the acute shortage of land resources, the negative ecological burden on water resources, soils and the atmosphere of these sludges in case of their accumulation without proper treatment. Anaerobic stabilization of food production wastewater sludge is one of the most widespread methods of processing this type of sludge due to the possibility of obtaining an important energy resource – biogas. The sludge obtained after anaerobic stabilization in methane tanks is called digestate, and it also needs treatment and further disposal. Digestate can be used as a fertilizer if sanitary and hygienic requirements are met. The development of a technological scheme for processing wastewater digestate is a complex issue that does not have one correct solution. A hybrid technological process for processing wastewater digestate of the food industry is proposed on the basis of experimental studies. Experimental studies include dewatering anaerobically stabilized sludge on a multi-disc dehydrator using dilution of the sludge itself due to its significant viscosity, addition of coagulant and flocculant. Cake with a moisture content of about 65–80% can be transported and used as fertilizer for agriculture. The separated filtrate from the digestate according to the technological scheme is proposed to be purified on two stages of membranes. The efficiency of cleaning the liquid fraction of the digestate on a two-stage membrane installation according to two variants showed the following results: variant 1 (VSEP + RO) – 95%, variant 2 (ZI + RO1 + RO2) – 94%. The VSEP system uses a hermetic RO membrane, so a two-pass membrane process (VSEP+RO) is suitable to achieve the end goal (permeate obtained can be reused), while a ZI membrane requires a three-pass membrane process to achieve the same goal. The achieved parameters make it possible to use the obtained permeate for the production needs of the enterprise or in the technological scheme of the digestate processing itself for dilution of the sediment or for the preparation of reagent solutions. The resulting products (cake and concentrates after membranes) can be used as fertilizers.

Published: December 2023

The paper analyzes the problems of the reagent method of wastewater treatment of machine–building enterprises, and the advantages of the magnetic sorption method in comparison with the reagent method are presented. The magnetosorption method, based on the treatment of a liquid with particles of a ferromagnetic material with the aim of sorption on their surface of substances to be extracted, has proven itself well not only in the purification of wastewater from impurities of heavy metals, but also from petroleum products, surfactants, radioisotopes, and suspended substances. The efficiency of water purification processes depends on the properties of the sorbent particles, such as dispersion, sorption capacity and magnetic properties of the particles. The paper presents the results on the dispersion of particles. Changes in the dispersion of synthetic magnetite particles obtained under various conditions, such as storage time, temperature, pH, K=[Fe2+]:[Fe3+] ratio, salt content, and nature of the precipitant, were studied. It is shown that with an increase in storage time, the number of small particles less than 10 μm decreases, and the number of large particles increases due to recrystallization processes. It has been determined that at 20 ℃ without the influence of a magnetic field, a suspension with a maximum content of particles with a diameter of 10 μm is formed, at a temperature of 40 –  70 ℃ particles with a size of 8 –  10 μm prevail in the suspension, and with an increase in the pH of the solution, the number of small particles in the suspension increases. Conversely, with an increase in salt content, the particle size increases with a decrease in the fraction of small particles by almost half. It is noted that at K = 0.8; 2.0, the largest number of particles (about 60 %) with a size of 10 μm are formed in the solution. It is shown that the maximum number of particles larger than 20 μm is formed using NaOH.
To the method of distribution drainage pipelines calculation with sloping groundwater level
Authors: Kravchuk Andriy , Kravchuk Oleksandr , Chabaniuk Roman , Kravchuk Olga
Published: December 2023

A methodology for assessing the influence of the error value, which is included in the calculations of distribution pressure drainage pipelines in the case of a groundwater surface slope, is proposed in the paper. It is based on the previously obtained solutions of the system of differential equations describing the liquid movement with variable flow rate in distribution pressure drainage pipelines that operate at the horizontal level of the groundwater surface. The analysis is presented in dimensionless form. The influence of the groundwater level slope on the calculation results is estimated using the value of the relative flow variation in the initial section of the distribution pipeline and the generalized parameter of the distribution drain A, which takes into account its design and filtration characteristics. The obtained calculation formulas are quite simple and easy to use. The proposed method allows to determine the limits within which simplified dependencies for the calculation of drainage pipelines can be used, which are recommended for use at the horizontal groundwater level on the land reclamation site. At the same time, the error introduced into the calculations as a result of the adopted simplification is immediately determined. Corresponding graphs are presented in the paper to illustrate the obtained dependencies.
Determination of active concentrations and velocities of phases in airlift three-phase flows
Authors: Kril Stepan , Skorokhod Iryna , Fadeichev Volodymyr , Orlova Lyudmyla
Published: December 2023

A one-dimensional ascending steady flow of a mixture of air, water, and solids in a vertical lift lift pipe is considered. As a physical model, this three-phase flow is represented as the compatible movement of the pulp (a mixture of liquid and solid particles) and compressed air in the form of shells. It is assumed that the lifting of solid material is carried out by liquid plugs that move in the intervals between the air shells. The purpose of the work is to determine the actual concentrations and velocities of the phases as one of the important hydrodynamic characteristics of the flow. The method of statistical averaging of these characteristics is used, similar to the theoretical-probabilistic method of averaging in the theory of turbulence, the basis of which is the transition from consideration of a single flow to consideration of a statistical set of similar flows carried out under almost identical conditions. The actual phase concentrations in any given live current section are considered in terms of the unconditional probability of one or another phase passing through the section. To determine the true velocities of the phases, hydraulic continuity equations are used, containing probability-averaged hydrodynamic quantities and describing each phase individually as some continuum in the statistical sense. In this case, the true velocity of a phase in any given live section is defined as the statistical average of the velocity, provided that this phase clearly intersects the section. The expressions obtained for the real concentrations and velocities of the phases form the theoretical basis for the construction of a hydraulic mathematical model of the three-phase flow with respect to the problem of airlift calculation.

Tingkat prevalensi kejadian stunting di seluruh dunia pada tahun 2020 mencapai 22% atau 149,2 juta jiwa. Data dari Studi Status Gizi Indonesia (SSGI) yang dilakukan oleh Kementerian Kesehatan (Kemenkes) melaporkan bahwa pada tahun 2021, prevalensi kasus stunting di Indonesia sebesar 24,4%. Tujuan penelitian ini yaitu untuk mengkaji kaitan antara penggunaan pestisida terhadap risiko kejadian stunting. Dengan menggunakan metode Literature Review, dilakukan analisis teradap berbagai penelitian terdahulu yang membahas terkait pestisida terhadap faktor risiko sutunting. Penelusuran dilakukan pada beberapa database yaitu, Google Scholar, Scopus, Pubmed, serta Science Direct. Kemudian dilakukan penyeleksian menggunakan alur PRISMA. Berdasarkan hasil dari pemilahan artikel jurnal, terdapat  2284 artikel yang ditemukan berdasarkan pencarian menggunakan kata kunci “paparan pestisida dan stunting” pada artikel nasional dan “pesticide exposure and stunting” pada artikel internasional. Sehingga berdasarkan pencarian menggunakan metode PRISMA ditemukan sejumlah 10 artikel jurnal penelitian yang membahas stunting akibat paparan pestisida secara mendalam. Dikarenakan pestisida memiliki kandungan Thyroid Disrupting Chemical yang dapat mengganggu hormon tiroid khususnya pada ibu dengan usia produktif. Kemudian didukung oleh berbagai faktor lainnya yang mempengaruhi stunting yang disebabkan oleh paparan pestisida. Oleh karena itu, dapat disimpulkan adanya suatu hubungan yang signifikan antara pestisida terhadap faktor risiko stunting.

Published: December 2023

Banyaknya limbah ikan berupa air cucian ikan yang digunakan oleh masyarakat mengakibatkan pembuangan limbah ikan semakin hari semakin meningkat. Pembuangan limbah ikan ke lingkungan secara langsung tanpa adanya pengolahan tidak hanya akan menimbulkan bau busuk yang sangat menyengat tetapi juga dapat mengganggu lingkungan. Penelitian ini bertujuan untuk mengetahui pemanfaatan limbah ikan menjadi POC dengan penambahan kulit buah nanas dan air cucian beras. Jenis penelitian yang digunakan dalam penelitian ini adalah eksperimen semu (Quasi Eksperimental) dengan melakukan uji coba pada limbah ikan dengan penambahan kulit buah nanas dan air cucian beras. Hasil penelitian pada pembuatan POC limbah ikan, POC limbah ikan dengan penambahan kulit buah nanas dan air cucian beras selama 21 hari ialah pada kualitas fisik bau amis (tidak memenuhi syarat) dan warna kuning kecoklatan (memenuhi syarat) sedangkan kualitas kimia pada POC limbah ikan dengan penambahan kulit buah nanas hasil nilai NPK (N+P2O5+K2O) = 0,35%, pada POC limbah ikan dengan penambahan air cucian beras hasil nilai NPK (N+P2O5+K2O) = 0,28%, dan POC limbah ikan hasil nilai NPK (N+P2O5+K2O) = 0,55% dinyatakan rendah atau tidak memenuhi standar dan pH memenuhi standar. Kesimpulan dalam penelitian ini ialah limbah ikan dengan penambahan kulit buah nanas dan air cucian beras dapat digunakan sebagai POC. Diharapkan agar peneliti selanjutnya memvariasikan waktu dekomposisi agar menjadi bahan ukur dalam proses jadinya POC dan memilih bahan organik yang mengandung nilai NPK yang tinggi.

Dengue Haemoragic Fever (DHF) selain menimbulkan masalah kesehatan masyarakat, tapi juga menjadi beban ekonomi yang cukup tinggi.  Jumlah kasus semakin meningkat dan penyebarannya semakin luas terutama di wilayah yang kondisi suhu dan kelembaban udara memungkinkan vektor Aedes spp hidup.Menghadapi persoalan tersebut,salah satu solusi yang dapat dikembangkan  adalah memberdayakan masyarakat melalui gerakan 1R1J. Tujuan dari penelitian ini adalah untuk mengetahui perbedaan ABJ DBD antara sebelum dan sesudah penggerakan masyarakat di desa Gheoghoma Kecamatan Ende Utara Kabupaten Ende. Metoda penelitian: jenis penelitian kuantitatif, rancangan satu kelompok yang sama diberikan dua perlakuan berbeda yaitu pre-intervensi-post. Penelitian tersebar di tiga dusun di desa Gheoghoma selama Pebruari-April2023. Populasi penelitian ialah 200 rumah tangga (RT) dan memilih 150 RT sebagai sampel yang diperoleh dengan metoda probabilitas, teknik simpel random sampling, dan memenuhi krteria inklusi.Data dikumpulkan melalui pengamatan jentik lalu dicatat pada format yang tersedia. Pengolahan data diawali dengan proses editing, coding, tabulasi, cek data akhir, lalu mengitung ABJ. Selanjutnya dilakukan uji normalitas dan dilanjutkan denganuji Wilcoxon. Hasil:ABJ sebelum intervensi adalah35,33%,dan setelah intervensi adalah84,7% (meningkat 49,37%).Setelah dilakukan uji normalitas diinterpretasikan data berdistribusi tidak normal dengan nilai asymp. Sig. (2-tailed) adalah 0.000, lebih kecil dari α 0,05. Kesimpulan: pemberdayaan masyarakat melalui gerakan 1R1J dapat meningkatkan ABJ DBD di desa Gheoghoma Kecamatan Ende Utara. Saran: para Jumantik rumah terlatih menjadi role model sambil mengajak keluarga lain dalam gerakan 1R1J sehingga perlu mendapat dukungan baik dari stake holder di desa maupun sector teknis yaitu Dinas Kesehatan dan Puskesmas.Selain itu perlu penelitian dengan mengembangkan ide dan inovasi baru

Published: December 2023

Salah satu pengendalian vektor nyamuk adalah menggunakan perangkap, yakni perangkap telur (ovitrap) yang akan diisi atraktan sebagai zat yang digunakan untuk menarik nyamuk betina untuk bertelur. Salah satu bahan yang dapat digunakan sebagai atraktan adalah kotoran sapi dan kotoran ayam yang dicampur dengan air.Tujuan dari penelitian ini adalah untuk mengetahui preferensi oviposisi nyamuk Aedes aegypti terhadap variasi atraktan (air kotoran sapi dan air kotoran ayam). Adapun jenis penelitian yang digunakan adalah eksperimen dengan 3 kali replikasi serta variasi atraktan yakni campuran air dengan kotoran sapi dan air dengan kotoran ayam dengan konsentrasi kotoran masing-masing 3% kemudian dilakukan pengamatan selama 7 hari setiap replikasi. Hasil penelitian menunjukkan rata-rata jumlah telur yang terperangkap berbeda-beda pada setiap media. Pada media air kotoran sapi sebesar 145,6, pada media air kotoran ayam sebesar 55 serta pada media kontrol sebesar 25,6. Hasil uji statistik menunjukkan nilai p value pada air kotoran sapi yakni sebesar 0,013 < 0,05 sedangkan nilai p value pada air kotoran ayam yakni sebesar 0,570 > 0,05 Kesimpulan pada penelitian ini yakni adanya perbedaan preferensi oviposisi nyamuk Aedes aegypti secara signifikan pada air kotoran sapi. Sedangkan pada air kotoran ayam terdapat perbedaan preferensi oviposisi nyamuk Aedes aegypti namun tidak secara signifikan. Media air kotoran sapi merupakan media yang menjadi preferensi utama bagi nyamuk Aedes aegypti untuk melakukan oviposisi jika dibandingkan dengan media air kotoran ayam. Disarankan untuk melakukan penetasan telur secara total dan penambahan variasi atraktan serta bagi masyarakat untuk memperhatikan kebersihan lingkungan guna menghindari perindukan nyamuk.
