Authors: Sugihyono Sugihyono
Published: April 2023

This study aims to conduct a theological study to answer questions, including: why did Boaz want to marry Ruth? Isn't Boaz a wealthy man, famous and of good character? and was not Ruth a poor widow, a cursed Moabite woman (Deuteronomy 23:3)? What was the advantage of the Moabite female Ruth, over the Israelite woman? Are there any values that Boaz held as a prerequisite for him to determine a life partner? In Ruth chapters 2 and 3, it shows that Ruth received preferential treatment from Boaz while picking up barley in her field, Ruth also received a good reception from Boaz when at night she came to her threshing place.  This is what the author refers to in discussing and developing this research, especially finding the values that Boaz has to get a wife, as well as knowing the character that Boaz and Ruth have to be a husband and wife who are commensurate with God's will. Using a qualitative approach with a literature study method, through the source of books and literature that correlates with this research problem.  From this research it can be concluded that both Boaz and Ruth both had very commendable characters who eventually united them into a commensurate and blessed husband and wife of God. However, above all there was God's involvement and guidance that made the process of Ruth and Boaz's encounter perfect.

Authors: Ayun Qurrata , Khomsiyah
Published: April 2023

Kulit buah naga merah yang seringkali hanya dibuang sebagai sampah, ternyata memiliki banyak manfaat dengan kandungan antosianin yang tinggi. Antosianin merupakan kelompok pigmen yang berwarna merah sampai biru yang tersebar luas pada tanaman. Antosianin juga merupakan zat warna yang berperan memberikan warna merah, yang dapat berpotensi menjadi pewarna alami untuk pangan dan dapat juga dijadikan sebagai alternatif pengganti pewarna sintesis yang lebih aman bagi kesehatan (Citramukti, 2008). Warna dari senyawa antosianin tergantung pada gugus fungsi yang terikat dan pH yang dimilikinya. Kemampuan senyawa antosianin untuk berubah warna akibat perubahan pH menjadikanya sebagai salah satu indikator alami yang banyak digunakan dan dikembangkan (Woodward, 2009). Kestabilan warna senyawa antosianin dipengaruhi oleh pH atau tingkat keasaman, dan akan lebih stabil apabila dalan suasana asam atau pH yang rendah. Berdasarkan permasalahan diatas, peneliti ingin mengetahui kestabilan senyawa antosianin jika ditambahkan dengan buffer phosphate pada pH yang divariasikan, sehingga dapat diketahui bentuk pergeseran puncaknya ketika diukur menggunakan spektrofotometer UV-Vis. Pada penelitian kali ini ada beberapa optimasi yang dilakukan antara lain adalah pengaruh kestabilan warna senyawa antosianin dimana setelah penambahan larutan pH 1 dan pH 4,5, campuran didiamkan selama 0, 15, 30, 45 dan 60 menit, untuk selanjutnya diukur kadar antosianinnya mengunakan metode pH differensial. Yang kedua variasi pH buffer phosphate yang divariasikan dengan pH 3 – 12 dengan interval 1 terhadap pergeseran puncak, dimana pergeseran puncaknya dilihat dari hasil pengukuran absorbasi pada panjang gelombang 400-700 nm. Berdasarkan hasil penelitian, warna dari senyawa antosianin stabil pada menit ke 0 sampai menit ke 45, untuk menit selanjutnya kestabilan warnanya menurun yang ditandai dengan menurunnya nilai absorbansinya. Untuk pergeseran puncak diperoleh hasil pH yang paling baik adalah ketika ditambahkan buffer phosphate pH 3, karena pada kondisi tersebut struktur senyawa antosianin yang paling stabil ditunjukkan oleh kandungan senyawa antosianin paling tinggi daripada pada penambahan pH yang lainnya

Authors: Yuan-Ko Huang
Published: April 2023

With the rapid advancements in mobile devices and wireless network technologies, the Internet of Things (IoT) has become more powerful and popular than ever. The aim of IoT is to efficiently control various types of objects through wireless communications. This paper aims to design an IoT-based smart lighting system that reduces development costs and saves power consumption. Unlike public open spaces, the focus of this paper is on ship cabin spaces. As ship cabins have unique properties, such as requiring gas-based power generation and preferring a wireless environment, designing a smart cabin lighting system is crucial and has significant commercial value. The smart cabin lighting system is designed with four features. Firstly, it can automatically control the lighting devices around people using position-sensitive devices. Secondly, it enables setting on/off and adjusting the luminance for lighting devices through Touch Keypads. Thirdly, the system can be controlled using an app to turn on/off and adjust the luminance of lighting devices. Lastly, the lighting devices equipped with sensors collect specific data on cloud servers for analysis. The underlying communication protocol used to interconnect the smart lighting devices, sensors, and Touch Keypads is Zigbee. The smart cabin lighting system can be applied to marine lighting, thus improving the commercial value of enterprises related to marine lighting.

Introduction: HPV is a family of double-stranded DNA viruses that infect the mucous epithelium. Most of these infections regress without consequences; however, the high-risk HPV viral strains can determine a tumor transformation of the epithelium, giving rise to tumor forms such
as cervical cancer. The analysis mostly applied to define abnormalities of the membranes is the PAP test and the treatment is reconciled, in most cases through prevention. Alongside the standard protocol, we have determined that a blend of essential oils has an effect in determining the negativization
of HPV. Materials and Methods: We made use of the BDORT technique in order to determine the specific percentages of each component of the prepared oil blend. To confirm this, two advanced Molecular Docking software have been applied (Swiss Dock and 1-Click Docking). The mixture of oils
was subsequently applied, in the form of vaginal capsules, on a group of HPV (+) positive patients, who were tested for the presence of a virus, before and after treatment, by RT-PCR, Colposcopy, and BDORT to evaluate the state of epithelium before and after the assumption of oil vaginal capsules.
Results: The mixture of oils has produced the negativization of HPV, determined by BDORT and confirmed by RT-PCR, in the treated patients. Discussion: We have determined that the blend of essential oils, prepared here, influenced the negativization of the virus, in all the patients
treated. Conclusions: The operative efficacy of these oils in the negativization of HPV has been demonstrated.

In the era of the Covid-19 pandemic, service activities to the community were limited by government regulations, which affected employee performance in fulfilling the wishes of the community in document processing. This study aims to explain the relationship between the variables of responsiveness, responsibility, and accountability for community satisfaction during the Covid-19 pandemic. The descriptive quantitative research method, with data analysis used, is Pearson correlation and distribution of questionnaires to 20 respondents who came to the Babakan urban village office in Tangerang City. The results of the study showed that the correlation value of the responsiveness variable to community satisfaction was 0.181 with a significance of 0.446 > 0.05, it was stated that the responsiveness variable did not exist a relationship between responsiveness with the level of community satisfaction. While the Pearson correlation variable of responsibility for community satisfaction is 0.586 with a significance of 0.015 ≤ 0.05 has a significant relationship between the variable of responsibility and community satisfaction, and the variable of accountability for community satisfaction of 0.575 with a significant 0.008 ≤ sig. 0.05 has a significant relationship between accountability variables and community satisfaction. So the implementation of services for the community in any condition still pays attention to the policies or rules of public service administration that prioritize the values and norms that apply in the community.
Politikointia koulussa – vai koululla?
Authors: Puustinen Mikko , Rantala Jukka
Published: April 2023

Artikkelissa analysoidaan, millaista kuvaa opetuksen poliittisuudesta rakennetaan verkkokeskusteluissa ja millaisia merkityksiä kouluun ja opettajiin liitetään. Aineistona ovat kouluopetusta käsitelleet verkkokeskustelut, jotka käynnistyivät tammikuussa 2021 Helsingin Sanomien ja Yleisradion uutisoitua Perussuomalaisen Nuorison aloitteesta ilmiantaa puolueellisia opettajia. Menetelmällisesti artikkelissa hyödynnetään retorista analyysia, retoris-performatiivista diskurssiteoriaa ja toiseuttavan verkkokeskustelun teoriaa. Osa aineiston keskustelijoista esitti koulun puolueelliseksi ja kyseenalaisti opettajien luotettavuuden. Toiset puolustivat opettajien ammattitaitoa. Yleisesti ottaen puheenvuoroista kuvastuu keskustelijoiden epätietoisuus siitä, miten koulun arvoperusta määritetään. Monissa kommenteissa pyrittiin toiseuttamaan opettajia kuvaamalla heidät eliitin edustajiksi. Verkkokeskustelussa esiintyvät kouluun kohdistetut syytökset poliittisen vastustajan tavoitteiden ajamisesta ovat ominaisia populististen ryhmien käyttämälle puhetavalle. Tulokset johtavat pohtimaan tarvetta käydä avoimempaa keskustelua koulun arvoperustan määrittelystä ja median kykyä asiantuntevaan koulu-uutisointiin.

Politiikan toimijoiden viestintä sosiaalisen median alustoilla on tärkeä osa vaalikampanjaa. Puolueen puheenjohtajan merkitys erityisesti eduskuntavaalikampanjassa on kiistaton, mutta toistaiseksi on vasta vähän tutkittu, millä tavalla he näkyvät ja millainen rooli heillä on puolueensa viestinnässä sosiaalisen median alustoilla. Tutkimus käsittelee puolueiden ja niiden puheenjohtajien kampanjaviestintää Suomen eduskuntavaalien 2019 yhteydessä henkilöitymisen näkökulmasta kolmella suurimmalla sosiaalisen median alustalla: Facebookissa, Twitterissä ja Instagramissa. Tavoitteena on tutkia, miten henkilöityminen ilmenee eri toimijoiden julkaisuissa. Tulosten mukaan sisällöt ovat vahvasti asiapitoisia. Ne ovat myös henkilökeskeisiä, mutta henkilökohtaista sisältöä julkaistaan niukasti. Lähtökohtaisesti sosiaalinen media ei vaikuta lisäävän yksityiselämän tuomista julkisuuteen, sillä suurelta osin henkilökohtainen sisältö on perinteisessä mediassa jo aikaisemmin jaettuja sisältöjä. Puheenjohtajilla on merkittävä viestinnällinen rooli sekä itsestään että puolueesta ja puolueen muista ehdokkaista viestivänä edustajana. Myös eri alustojen välillä havaitaan eroja. Twitter nousee vahvasti asiapitoisten sisältöjen alustaksi, kun taas Facebookissa ilmenee eniten henkilökohtaista sisältöä. Instagramin käyttö sen sijaan jää vielä varsin vähäiseksi vuoden 2019 kampanjassa.

Demotivating Factors in English Language Learning as Perceived by Newly Hired English Language Teachers
Authors: Quines Zaldy Maglay
Published: April 2023

Many researches claimed that motivation is a great factor in the teaching-learning-process. On the other hand, only few researches investigated the impact of demotivation in learning. There are many factors that demotivate learners and affect English language classes. This study aimed to investigate the perceived topmost factors that cause demotivation in English language learning. The data for this study were collected by means of a questionnaire about factors that demotivate learners. Newly hired English teachers from ELPYI- JTI, Royal Commission for Jubail and Yanbu responded to the questionnaire. They were chosen as respondents because they can literally connect to the younger generation. The collected data were analyzed by arranging the rating and ranking given for each factor. The analysis of the gathered data revealed a number of results. First, “Students’ Behavior” and “Teacher’s Behavior” are rated and ranked as the leading demotivating factors in English language learning. Second, “Poor Teaching Style” and “Poor Learning Style” are categorized as the topmost demotivating factors related to teachers and students. Third, “convenience” of the classroom is also perceived as a high factor of demotivation. Last, “Course/Lesson”, and “Course Requirements” are classified as the least demotivating factors that affect learning the English language.

Published: April 2023

This paper focuses on the determination of both the presence and concentration of phthalate esters in three tributaries of Asa River in Kwara State, Nigeria.Water samples were collected at different points from each of the three tributaries (Unity, Osere and Yidi streams) and a total number of 18 samples were collected and the concentration of the prevailing phthalates was determined using GC-MS. Seven different phthalates were found present in the samples and they are: DMP, BBP, DEHP, DNOP, DEP, DBP, and DNHP. The concentration of DMP in the 18 samples ranged from 0.114 -0.525 μg/L, BBP (0.266-0.697 μg/L), DEHP (0.086- 0.198 μg/L), DNOP (0.062- 0.456 μg/L), DEP (0.162- 0.679 μg/L), DBP (0.168- 0.399 μg/L), and DNHP (0.010-0.064 μg/L). The total phthalate concentration in the three tributaries was lower than the USEPA limit of 3 μg/L for fishes and aquatic lives except for Unity stream where the total was 3.018 μg/L. This study was carried out during the rainy season and the result obtained here could be used as a reference for a further study during dry season to compare the impact of seasonal variation on the distribution and concentration of phthalate esters in the selected tributaries.

In developing countries such as Pakistan, atmospheric pollution has become a disaster. This study's objective was to observe and evaluate the air quality in the 15-million-person combined population of the twin cities of Rawalpindi and Islamabad in Pakistan. The quantities of particulate pollution, as well as CO2, were measured in five different cities. There are now far too many types and sources of pollution from numerous air pollutants. However, due to an absence of management skills for air pollution, the world is currently facing diminishing air quality. The ecosystem, public health, and quality of life are all seriously threatened by air pollution, according to facts from multiple governmental organizations and foreign organizations. Through the Pakistan Environmental Protection Program, the Pakistani government has implemented important strides toward air quality management, including the establishment of few active monitoring stations. However, there are currently no standards for environmental protection. This paper examines the standards for air pollutants from observational studies. Five main air pollutants—NO2, SO2, CO, O3, and PM2—were taken into consideration. Our findings show that under the baseline scenario, Existing air pollution in Pakistan management efforts are inadequate to achieve the nation's air quality criteria. By 2050, the percentage of deaths caused by PM2.5 will be 24% lower nationwide because of the implementation of sustainable development policies. Innovative standard precautions can improve Pakistan's air quality and public health, but when associated with foreign long-term new developments, they can also lower greenhouse gas emissions (implementing SDG 13's indicator on climate action) and save about a quarter of GDP (0.32% of GDP) on costs associated with emission control by 2050. It seems to have a substantial co-benefit in terms of cost (economic), health (social), and air pollution (environmental), suggesting that Pakistani public policy should consider a co-control at a low cost of greenhouse gases and air pollution in the future.

Published: April 2023

Community leaders are not focused on the literacy skills of the people they lead. It can be construed that the higher the rate of a community’s illiteracy, the more difficult it is for the community to develop. A look at Kenya shows that well equipped libraries for various constituencies is abysmal. Libraries can accelerate knowledge acquisition by the public through distance education. The study uses analytic methodology to critique lack of public libraries in Kenya. Analysis of community illiteracy rate reveals that the problem can better be addressed by community members playing the part of activists. Since activism is allowed in Kenya Constitution 2010, it becomes the only recourse to impel members of parliament and county assemblies to accelerate the setting up libraries in their areas of their jurisdiction and in this regard, activism is vital for social change. This study recommends more research to be carried out in Kenya on the need for and setting up more libraries for the citizens.

Authors: Larrea Simball Leopoldo Javier , Tutiven Abad Tanya Cecilia
Published: April 2023

All human beings have the right to life; however, when it comes to the unborn child or nasciturus, the controversy about whether it is the subject of this right is heightened, especially when the debate takes place in the preamble of the discussion of laws that approve or criminalize abortion. Consequently, the present study aims to analyze the positions of different authors in relation to the right to life of the unborn child from the analysis of human rights. In order to fulfill this purpose, a theoretical research was carried out, based on the review of scientific articles and documents related to the subject, and the use of inductive, analytical and synthetic methods. As a result, it was determined that the condition of the nasciturus as a person cannot be denied, therefore, its right to life must be guaranteed from conception according to the contents of the Universal Declaration of Human Rights.
