Published: July 2023

Quasi-experimental research or quasi-experimental research is an innovation from true experimenters, including difficult research in the fields of education and social. Although this research is difficult to do, many researchers are also interested in using a quasi-experimental design in conducting research, especially in the field of mathematics. The high interest of researchers in this study is due to the fact that quasi-experimental research is most suitable to be applied in research in the field of mathematics education which is the subject of instructional research by educators and students. Quasi-experiments are used to make it easier to control due to non-functioning due to the control group as an external variable that also has an effect. The study conducted in this study used a literature review, broadly speaking, research data collection was based on observations of related research journal articles that had been carried out by other researchers before. Quasi-experimental studies as a research vehicle that aims to examine the application of quantitative research in testing students' problem-solving abilities. Researchers need more accurate methods to be applied, theoretical studies and analysis results can be concluded that quasi-experimental research can be used as an alternative to problem solving in problem-based mathematics learning. Based on the analysis of the researcher's interest, it can be seen that in fact the researcher uses a test instrument to see the effect of solving students' mathematical problems by applying the random sampling technique.

Published: July 2023

Bitter seed (Andrographis paniculata (Burm. f.) Wall. ex Nees) is a medicinal species used in phyto pharmacy and known as ‘the king of bitterness’. Bitter seeds contain andrographolide,
a diterpenoid lactone which is widely used in Indian medicine for snake bites and for the treatment of hepatitis. The research was conducted at the Seed Management Unit experimental field of the Indonesian Spice and Medicinal Plants Research Institute (IMACRI) and at the Seed Quality Testing Laboratory of IPB University, Indonesia, from January until May 2021. The objectives of the study is to determine the best germination test and effective breaking dormancy techniques to increase the germination percentage of bitter seeds. The study was arranged in a completely randomized design with two-factors. The first factor was seed treatments, i.e., control/untreated, chemical scarification with 5% H2SO4 for 10 minutes, and 5% H2SO4 followed by a 100 ppm GA3 soaking treatment. The second factor conducted was germination test methods according to International Seed Testing Association, i.e., germinating the seeds on the top of paper and in pleated paper. Our study demonstrated that seed treatment with H2SO4 can break seed dormancy and speed up seed germination. Bitter seed germination on the pleated paper was higher than with the top-of-paper method. Bitter seed germination with the top-of-paper method was at 65 DAS and the final germination was at 80 days after sowing (DAS), and the final germination was 55.2%. With the pleated paper method, the seeds germinated at 30 DAS and the final germination was at 70 DAS, and the final the germination of 59.2%.

TEUNGKU MUHAMMAD HASBI ASH-SHIDDIEQY'S CONCEPT OF MARRIAGE: A Maqasidi Approach to Polygamy and Interfaith Marriage Verses in Tafsir An-Nuur
Authors: Ibrahim Muhammad Syahrial Razali 
Published: July 2023

<p><strong>Abstract: </strong>The aim of this article is to elucidate modernist Islam position on the discourse of poligamy and interfaith marriage based on the work of Hasbi <span>ash-Shiddieqy</span>’s<strong><em> </em></strong><em>Tafsīr An-Nuur</em>. In response to the issues, he argues that the objectives of Shari`a are pivotal. The law on poligamy and interfaith marriage are both contextualised by the realisation of Shari'a objectives. Here, he views that both of poligamy and interfaith-marriage are forbidden for the first is incapable of actualisation domestic justice, while the second is against Shari'a maqashid; <em>hifdh al-dīn</em>/<strong> </strong>the protection of sound religious practices. By relying on descriptive analytic of Hasbi’s work on the tafsir, it is found that he views the domestic justice encrypted in al-Nisâ’ 3 and 129 is both physical needs and psychological actualisation, which are to some extent impossible to be achieved by poligamy. He furthers accordingly that interfaith marriage is prone to deteriorate Islamic principles and practices.</p><p><strong>Abstrak: </strong>Pernikahan adalah sunnatullah yang bertujuan mendapatkan ketenangan jiwa, membina keluarga dan menjaga keberlangsungan umat manusia atas nilai-nilai ketaatan kepada Allah. Atas dasar ini para ulama kemudian memberi batasan, bahkan melarang poligami dan nikah beda agama karena diyakini adanya <em>mafsadah</em> yang dapat mengganggu tercapainya tujuan pernikahan. Kajian ini ingin melihat pandangan Hasbi Ash-Shiddieqy melalui karyanya <em>Tafsir An-Nuur </em>terkait larangan poligami dan kebolehan menikahi perempuan non muslim, seperti perempuan Yahudi, Nasrani, Hindu, Budha dan lainnya. Dengan menggunakan metode deskriptif analitis interpretif, peneliti menyimpulkan bahwa Hasbi Ash-Shiddieqy melarang poligami karena anggapan ketidakmampuan seorang suami mengimplementasikan makna adil. Menurutnya, adil dalam surah al-Nisâ’ 3 dan 129 mencakup adil materi dan <em>ruhi</em>. Begitu juga halnya dengan larangan menikahi perempuan musyrikat, ia meyakini <em>mafsadat</em> yang akan muncul lebih besar, yaitu kemurtadan dan kekafiran. Namun ia membolehkan nikah <em>kitabiyat</em> secara mutlak. Masuk dalam kategori <em>kitabiyat</em> menurutnya perempuan Hindu, Budha dan sejenisnya.</p><p><strong>Keywords:</strong> interfaith marriage, poligamy, Hasbi Al-Shidiqy, and Modernist Islam</p>
АНТИЧНІ МОНЕТИ VI–I СТ. ДО Р. Х. НА ПОДІЛЛІ
Authors: Orlyk Vasyl 
Published: July 2023

Мета статті полягає у дослідженні та систематизації монетних знахідок на території Поділля та введення їх до наукового обігу. Теоретико-методологічні основи дослідження складає сукупність загальнонаукових та нумізматичних методів, які найперше визначаються наявною джерельною базою та оцінкою щодо її достовірності чи недостовірності. Наукова новизна. Протягом останніх десятирічь значно збільшилася кількість відомих знахідок античних монет на поселеннях VI–I ст. до Р. Х. у різних регіонах України, в тому числі й на Поділлі. Проте, узагальнююче комплексне дослідження знахідок монет VI–І ст. до Р. Х. з Поділля та прилеглих до нього територій відсутнє, що й обумовило звернення автора до заявленої теми та написання даної статті. Основні результати дослідження. Аналіз знайдених 118 античних монет VI–І ст. до Р. Х. на території Поділля дозволив виокремити 7 пунктів зосередження таких знахідок, зокрема 4 населені пункти, поблизу яких знайдено кілька одиничних монет, і 3 населені пункти, неподалік від яких виявлено одиничні монети та монетні скарби. Окрему категорію серед корпусу подільських монетних знахідок складають 12 «демонетизованих» монет (11,65 %), тобто таких, що оформлені як прикраси. Наявність корпусу знахідок античних монет VІ–І ст. до Р. Х. на території Поділля, у тому числі знахідок монетних скарбів, пунктів скупчення одиничних знахідок, особливо локацій з поєднанням скупчення таких знахідок і скарбів, а також наявність серед монетних знахідок «демонетизованих» монет, дала підстави для визначення ймовірності існування в цьому історичному регіоні України в досліджуваний період товарно-грошового господарства з використанням монет як платіжного засобу. Хоча зрозуміло, ці товарно-грошові відносини не були настільки розвинутими, як у грецьких колоніях Північного Причорномор‘я та в сусідніх фракійських племен. У статті на підставі аналізу нумізматичних джерел доведено, що Північно-чорноморська торгівля на теренах Поділля в VI–І ст. до Р. Х. була пов‘язана з Ольвією, особливо протягом IV–ІІІ ст. до Р. Х. А південно-західний вектор торгівельної діяльності населення Поділля в VI–І ст. до Р. Х. був пов‘язаний із фракійськими землями, звідки надходили не лише монети грецьких колоній Західного Причорномор‘я та фракійські монети, а й частково монети Македонії. Найбільше знахідок фракійських та македонських монет припадає на емісії IV–ІІІ ст. до Р. Х.

Мета статті полягає у доповненні та систематизації дрібних мідних монетних типів та їхніх різновидів емітованих у першій чверті-середині ІV ст. до Р. Х., і укладенні їхнього каталогу.
Стаття є результатом багаторічної праці автора над архівом штемпелів ольвійської міді першої половини IV ст. до Р. Х. з подальшим дослідженням із застосуванням сукупності нумізматичних методів, а саме: візуального аналізу, ідентіфікації та типологізації монет, порівняльного методу.
Наукова новизна полягає у поділі усього корпуса на чотири групи, які представлені максимальною кількістю типів і різновидів, 30 з яких раніше були неопублікованими. Дана робота складає один із сегментів ольвійської нумізматики. У кожній окремій публікації автор переслідує мету максимально опрацювати опубліковані матеріали та додати нові знахідки з їх подальшим осмисленням.
Вагомий внесок нумізматичного матеріалу, який мав місце у сфері нумізматичних досліджень протягом останніх 30 років, багато в чому змінив уявлення про монетну справу Ольвії в цілому. До пріоритетних аспектів нумізматичних досліджень належать архівація та введення до наукового обігу нового нумізматичного матеріалу з метою створення бази штемпелів. Як показують реалії, багато навіть добре вивчених періодів піддаються корекції та змінам.

Published: July 2023

IntroductionLassa fever constitutes a threat to the public health system in Nigeria with the reoccurring annual epidemics and its attendant risk communication intervention challenges.ObjectiveThis study examined the influence of public alarm (if any) on respondents' comprehension of risk communication messages about the most common host of the Lassa virus, modes of transmission, risk factors, and protective measures for Lassa fever. The risk communication model (mental noise hypothesis) served as the benchmark for measuring respondents' perceptions in the most endemic states in Nigeria.MethodThe study adopted a quantitative approach, using the survey method. Data for this study were collected from 653 respondents through a structured questionnaire. Respondents were selected through a multi-stage sampling technique. Frequency tables were used to profile the respondents' characteristics and key variables while regression coefficients were used to draw inferences.ResultsThe study found a high level of perceived public alarm among the respondents but maximum attention was paid to risk communication messages amid the high level of anxiety. Knowledge of the common Lassa virus-host, modes of transmission, risk factors, and risk reduction measures was adequate irrespective of the high level of perceived public alarm. Public alarm significantly influenced audience comprehension of the risk information about Lassa fever in Ebonyi and Ondo at r2 = 0.040 and 0.076, at p &lt; 0.05 but not in Edo state at r2 = 0.010, at p &gt; 0.05.ConclusionThe authors conclude that devoting adequate attention to outbreak communication messages amid a high level of anxiety could lead to improved knowledge of infectious diseases.

BackgroundLittle research has been assessed atherosclerotic risk factors at various stages of calcific aortic valve disease. This study sought to determine risk factors of patients with aortic valve sclerosis (AVS) and mild to moderate aortic stenosis (AS).MethodsThe study included 1,007 patients diagnosed with AVS or mild to moderate AS according to echocardiographic criteria. Patients were identified as a rapid progression group if the annualized difference in peak aortic jet velocity (Vmax) between two echocardiographic examinations was &gt;0.08 m/s/yr in AVS and &gt;0.3 m/s/yr in AS, respectively. We used multivariable logistic regression analyses to assess the factors associated with rapid disease progression or progression to severe AS.ResultsAmong 526 AVS patients, higher LDL-C level (odds ratio [OR] 1.22/per 25 mg/dl higher LDL-C, 95% confidence interval [CI] 1.05–1.43) was significantly associated with rapid disease progression. Compared to patients with LDL-C level &lt;70 mg/dl, the adjusted OR for rapid progression were 1.32, 2.15, and 2.98 for those with LDL-C level of 70–95 mg/dl, 95–120 mg/dl, and ≥120 mg/dl, respectively. Among 481 mild to moderate AS patients, the baseline Vmax (OR 1.79/per 0.5 m/s higher Vmax, 95% CI 1.18–2.70) was associated with rapid progression. Compared to patients with Vmax 2.0–2.5 m/s, the adjusted OR for rapid progression were 2.47, 2.78, and 3.49 for those with Vmax of 2.5–3.0 m/s, 3.0–3.5 m/s, and 3.5–4.0 m/s, respectively. LDL-C and baseline Vmax values were independently associated with progression to severe AS.ConclusionAtherosclerotic risk factors such as LDL-C were significantly associated with the rapid progression in AVS and baseline Vmax was important in the stage of mild to moderate AS.

Published: July 2023

IntroductionThe transition from primary to secondary school is a period that can affect students negatively, with regular drops in academic achievement observed. Training students’ self-regulated learning skills might help prevent some of the negative outcomes associated with the transition. We investigate Talent Talk and Talent Lesson interventions, which aim to improve students’ metacognitive and affective self-regulation through enhancement of personal significance and strengthening of task-analysis skills.MethodThe present study researched whether Talents Talks and Talent Lessons can be used to improve students’ self-regulated learning skills, motivation, and self-efficacy. We employed a quasi-experimental 2 × 2 design comparing four groups (total N = 233), who received either Talent Talks or Talent Lessons, both, or neither. Students were tested at three separate moments on absolute monitoring accuracy and self-report measures of self-regulated learning, motivation, and self-efficacy, with the interventions being implemented between the first and second moment.ResultsThere were no significant differences between conditions at any of the test moments.DiscussionAs such, there is at present no evidence suggesting that Talent Talks and Talent Lessons positively influence self-regulation, self-efficacy, and motivation. Effectiveness of the intervention might be increased if Talent Talks and Talent Lessons are adapted, so that students’ reflections about talents are tailored to self-regulation of specific tasks.

IntroductionAlthough Ethiopia has implemented the Option B+ program over the past 7 years, loss to follow-up among HIV-positive women remains a major problem for antiretroviral therapy (ART) treatment. This study was conducted to investigate the number of women who dropped out of follow-up after the Option B+ program.MethodsA retrospective follow-up study was conducted among 403 pregnant and lactating women between June 2013 and December 2019 at health facilities in Northwest Ethiopia. The Cox proportional hazards regression model was used to identify predictors of loss to follow-up. The results were reported as hazard ratios with 95% confidence intervals (CIs) at a significance level of p = 0.05.ResultsThe overall incidence rate of loss to follow-up was 9.4 per 1,000 person-months of observation (95% CI: 7.40–11.90). According to the multivariable Cox regression, rural residency [adjusted hazard ratio (AHR): 2.30; 95% CI: 1.08–4.88], being a Muslim religion follower (AHR: 2.44; 95% CI: 1.23–4.81), having no baseline viral load measurement (AHR: 4.21; 95% CI: 2.23–7.96), being on ART before enrolment (AHR: 0.30; 95% CI: 0.15–0.62), having drug side effects (AHR:1.82; 95% CI: 1.01–3.33), same-day ART initiation (AHR: 3.23; 95% CI: 1.53–6.84), and having suboptimal adherence level (AHR: 3.96; 95% CI: 2.18–7.19) were significant predictors of loss to follow-up.ConclusionThe incidence of loss to follow-up is lower as compared to evidence from most African countries but slightly higher than the WHO target. It is better to strengthen and expand viral load measurements for all women and to pay attention to women residing in rural areas with fair or poor adherence levels.
