This study explores first-year undergraduate students’ argumentation essays using argument diagramming structure. A corpus-driven data of 394 argumentative essays were gathered from both Indonesian and Thai universities. A content analysis was employed to examine the dataset of the students’ argumentative essays. After gathering primary information from the body parts of their essays, we subcategorized their argumentations into claims and premises in a compliant reading. To ensure data trustworthiness, this study employed triangulation by source and method. The findings show that the most prominent type of argument diagramming was a basic argument, followed by convergent and divergent arguments. Regardless of how the argument diagramming was written, the study found that the students still lacked mastery in structuring their logic when building up the case to be extended to claims and premises. This study suggests a need to revisit pedagogical instructions, in which there should be a provision not only on the basic knowledge of argument structures but also on the skills to recognize the quality of a good argument cognitively. This additional practice will provide important insights to recognize the representational strengths and weaknesses of the students’ argumentative writing proficiency to achieve a better performance in the content of their essays.

Kajoran Sub-district is a horticultural production center that supplies horticultural commodities for Central Java Province, especially Magelang. However, plant viral diseases of Kajoran have not been studied. This paper aimed to identify plant viral diseases in this horticultural production center. Some samples were taken: three potatoes (Solanum tuberosum) and three shallots (Allium cepa var. aggregatum), then tested respectively with RT-PCR, using two pairs of universal primers to detect Potyvirus and Carlavirus. The result showed two potato samples were infected by Potyvirus (potato virus Y/PVY) and three shallot samples by Carlavirus (shallot latent virus/SLV). GenBank accession no. OR180052 to OR180056 were assigned to the obtained partial sequences of the five isolates. The phylogenetic analysis makes the two new PVY Indonesian isolates in strain N group thus confirmed the presence of the first PVYN in Indonesia. The constructed SLV phylogenetic tree clusters the new three isolates with eight shallot isolates in a group and separated it from isolates from other plant species. The tested PVY isolates shared 95.2 to 100% nucleotide identities among them, while 78.9 to 98.5% identities were estimated among compared SLV isolates. This study expands our understanding of the genetic variation of PVY and SLV in Indonesia, potentially leading us to find the perfect management for the viruses.

This study aimed to explain the concept of character education contained in the book of Hikam and its relevance to Indonesia's national character education program. This research had been library research that used the content analysis technique. The data collection technique used the documentation technique. The findings in this study were that the concept of character education in the book of Hikam had been religious character education which refers to the character of Uluhiyyah (divinity), namely, humans must orient all their life activities to God by spreading goodness wherever they are. The closer and more obedient a person is to his God, the more character and noble that person will be. This religious education is an exercise (riyadhah) and sincerity (mujahadah) that is planned and systematic and carried out by an educator to form a pious personality in a student physically and spiritually. The concept of religious character refers to faith, honesty, piety, sincerity, and patience. Religious character educates a human being to become a person of character and responsibility. The character education values in the book of Hikam strengthen Indonesia's national character education program. In Sheikh Ibn Atha'illah's view, the character education strategy is divided into two stages: planting and spreading. Religious education is very relevant to the national character education strategy, namely intervention (instilling character in students) and habituation (instilling character through the environment). Studi ini bertujuan menjelaskan konsep pendidikan karakter yang ada dalam kitab Sufi Hikam serta relevansinya terhadap program nasional pendidikan karakter yang ada di Indonesia. Penelitian ini adalah library research yang mengunakan teknik content analisa. Teknik pengumpulan data yang digunakan adalah teknik dokumentasi. Temuan dalam penelitian ini adalah konsep pendidikan karakter yang ada pada kitab sufi Hikam adalah pendidikan karakter religious yang mengacu pada karakter Uluhiyyah (ketuhanan), yakni manusia harus mengorientasikan segala aktivitas kehidupanya kepada tuhan dengan menyebarkan kebaikan dimana saja berada. Semakin dekat dan taat seseorang kepada tuhanya maka orang tersebut akan semakin berkarakter dan berakhlak mulia. Pendidikan religius ini merupakan suatu latihan (riyadhah) dan kesungguhan (mujahadah) yang terencana dan sistematis, serta dilakukan oleh seorang pendidik untuk membentuk kepribadian yang shaleh pada seorang anak didik baik dari segi jasmani maupun rohaninya. Konsep karakter religius ini mengacu pada nilai-nilai keimanan, kejujuran, ketakwaan, keikhlasan dan kesabaran. Kitab Hikam mendidik seorang manusia menjadi pribadi yang berkarakter dan bertangung jawab. Nilai-nilai pendidikan karakter pada kitab Hikam menguatkan program nasional pendidikan karakter di Indonesia. Strategi pendidikan karakter dalam pandangan Syeikh Ibnu Atha’illah dibagi dalam dua tahap, yaitu proses penanaman dan penyebaran. Hal ini sangat relevan dengan strategi pendidikan karakter nasional, yaitu intervensi (penanaman karakter pada diri peserta didik), dan habituasi (penanaman karakter melalui lingkungan).

Hairy fig (Ficus hispida) fruits (HFF) are widely consumed as food and traditional medicine in several West Asian countries, both the unripe fruit (UHFF) and ripe fruit (RHFF). However, they are not commonly utilized in Indonesia. Acute oral toxicity studies reported No Observed adverse effect level (NOAEL). Further, a reproductive toxicity study found that UHFF boosted spermatogenesis and increased the quality and quantity of spermatozoa. Meanwhile, RHFF exhibited the opposite effects. To provide comprehensive information from the previous study, this research was conducted to evaluate the hemotoxicity of UHFF and RHFF about their impact on the male reproductive system. Nine Wistar rats were assigned into three groups: the first group received UHFF juice, the second group received RHFF juice, and the third group received distilled water as control. The volume of each treatment was 2 mL/individual/day for 77 days. On days 0, 28, and 77, blood samples were collected for routine hematological profile examination using a hematology analyzer (Sysmex®XP-100). Data were analyzed using a one-way ANOVA test and Duncan's test (α=0.05) to discover significant differences between groups and times. Results showed that consuming hairy fig fruit, especially the UHFF, had an unfavorable effect on erythrocytes resulting in hypochromic microcytic anemia. Still, there was no adverse effect on leukocytes and platelets. Anemia may have occurred due to the presence of hemotoxic compounds that interfere with the synthesis and binding of hemoglobin or because the hairy fig fruit filtrates were oxidized, thereby increasing the level of oxidative stress within the body, of which is a drop in hemoglobin levels.

Onchidiid slug or Onchidium typhae is a marine animal commonly found in West Kalimantan waters. This gastropod is commonly used as medicine and cosmetic by the locals. This research aims to assure the content and quality of O. typhae methanol extract by determining its secondary metabolites and heavy metal contamination. Phytochemical screening of alkaloid, steroid/ triterpenoid, flavonoid, tannin, and saponin are done using reagent tests. Chromatography profile was completed using silica gel G60 F254 plate and hexane: ethyl acetate: methanol as mobile phase. Heavy metal contamination analysis was performed using atomic absorption spectrophotometry to determine Hg, As, Cd, and Pb content. The phytochemical screening and chromatography profile of O. typhae methanol extract confirm the presence of alkaloids and steroids. Heavy metal analysis stated Hg, As, Cd, and Pb content in O. typhae are < 0,0008; < 0,001; < 0,001; and 0,05 ppm respectively. Since heavy metal levels are below the maximum contamination limit, it qualifies as a natural product ingredient.

Nowhere and everywhere: Navigating gendered urban spaces in Haruki Murakami’s After Dark Urban space has been one of the most underexplored elements analyzed in literary works. However, as urban space gradually emerges as a culturally influencing element, a casual perusal of any text that employs urban space might result in an oversimplified analysis. This study examines the urban space of After Dark (2004), authored by Japanese writer Haruki Murakami (b. 1949). Accounting for the ways urban space is interwoven with the socio-cultural context, this study establishes a spatial reading of Murakami’s After Dark through the description of the city. With a poststructuralist approach, this study discusses how urban space is utilized and how it serves as an important part of the text instead of a mere backdrop; it reinforces the possibilities of setting as a thematic approach to major issues such as self-identity and the marginalization of women. As it is concluded, the urban space the novel presents have succeeded to show that they form, to some extent, women’s behaviours both directly and indirectly. Hence, the setting may present the main theme further analysed. Keywords: urban space, spatiality, women, self-identity, marginalization Tak di sana dan di mana pun: Menavigasi ruang kota bergender pada novel After Dark karya Haruki Murakami Selama ini ruang urban masih menjadi unsur yang paling kurang digali dalam menganalisis karya sastra. Namun demikian, seiring dengan kenyataan bahwa ruang urban lambat-laun hadir sebagai unsur yang secara kultural berpengaruh, kajian kasual mengenai suatu teks yang memanfaatkan ruang urban mungkin justru menghasilkan analisis yang terlalu sederhana. Kajian ini menelisik ruang urban After Dark (2004), hasil karya pengarang Jepang, Haruki Murakami (lahir 1949). Dengan berpusat pada cara-cara ruang urban berjalin berkelindan dengan kontek sosio-budaya, kajian ini menghadirkan pembacaan ruang terhadap karya Murakami yang berjudul After Dark melalui deskripsi tentang kota yang digunakan sebagai latar. Dengan pendekatan pascastruktural, kajian ini membahas bagaimana ruang urban dimanfaatkan serta bagaimana hal tersebut menjadi bagian penting dari teks dan bukan hanya sekadar latar belakang; hal ini mendorong hadirnya kemungkinan latar sebagai subjek tematik untuk membahas isu-isu besar seperti identitas diri dan marjinalisasi perempuan. Sebagaimana yang diperoleh di kesimpulan, ruang urban yang ditampilkan dalam novel ini telah berhasil menunjukkan kemampuannya untuk membentuk perilaku tokoh-tokoh wanitanya baik secara langsung maupun tidak langsung. Dengan demikian, latar tempat dapat menunjukkan tema utama sebuah karya yang layak diteliti lebih lanjut. Kata kunci: ruang urban, spatialitas, perempuan, identitas-diri, marjinalisasi

Cardiovascular disease is the main cause of death worldwide and in Indonesia. Public awareness and acceptance of preventative cardiovascular care are crucial for reducing illness-related morbidity and mortality. As a result, community service is essential for the primary prevention of cardiovascular disease. Between April and July 2019, this community service was undertaken in Ngangkrik Hamlet, Sleman Regency, Yogyakarta Special Region (DIY). Ngangkrik locals participated in this program in three categories: Bapak Bijak (Wise Dads), Ibu Cerdas (Smart Moms), and Pemuda Bijak (Wise Youngsters). Five stages comprised this program: planning, informing, preparation, implementation, and oversight. Lectures/courses, discussions, practice, and roleplaying were used to implement the materials. To examine participants' knowledge, the pretest and posttest approach was utilized. The program raised participants' knowledge and understanding about the prevention and treatment of cardiovascular disease across all categories.

Patients with an autoimmune disease could be at higher risk of a poor outcome when contracting COVID-19 infection due to aberrant immune responses and use of immunosuppressant therapies for chronic autoimmune treatment. Here, we conducted a retrospective study to identify the factors related to severity, hospitalization, and mortality among patients with autoimmune diseases. We found 165 cases of patients with pre-existing autoimmune diseases who had contracted COVID-19 between March 2020 and September 2022. Data on demographical characteristics; autoimmune diagnosis and treatment; COVID-19 vaccination status; and time, severity, and outcome of COVID-19 infection were collected. Most of the subjects were female (93.3%) and autoimmune diagnoses included systemic lupus erythematosus (54.5%), Sjogren’s syndrome (33.5%), antiphospholipid syndrome (23%), vasculitis (5.5%), autoimmune thyroid disease (3.6%), rheumatoid arthritis (3.03%), and inflammatory bowel disease (3.03%) among other autoimmune diseases. There were four COVID-19-related deaths in this study. Factors associated with moderate to severe COVID-19 infection in patients with autoimmune diseases included not being vaccinated against COVID-19, taking a steroid of ≥10 mg prednisone-equivalent per day, and having a cardiovascular disease. Taking a steroid of ≥10 mg prednisone-equivalent per day was also associated with hospitalization in the event of COVID-19 infection, while cardiovascular diseases also showed a significant correlation to mortality in patients with autoimmune diseases who had been hospitalized with COVID-19 infection.

This study aims to investigate the effect of profitability and effective tax rate on capital structure with accounting conservatism as a moderating variable. The population are companies listing on Indonesia Stock Exchange in the last 5 years after the global crisis in 2008 that is 2014-2016 with 115 companies. The research sample was selected using purposive sampling technique. Based on the criteria, there are 67 samples with 201 units of analysis. Data were analyzed using moderate regression with SPSS 21. The results indicated that profitability has a negative effect on the capital structure. In contrast, effective tax rate has a positive effect on the capital structure. Accounting conservatism is a kind of pseudo-moderation that has a positive influence on the capital structure. However, as a moderating variable accounting conservatism is only able to moderate the effect of effective tax rate on capital structure. The results indicated that accounting conservatism significantly weakens the effect of effective tax rates on the capital structure. Based on the results, it can be concluded that the capital structure is influenced by profitability, effective tax rate, accounting conservatism, and the effect of effective tax rate on capital structure moderated by accounting conservatism.

Onchidiid slug (Onchidium typhae) is a nudibranch that coastal communities in West Kalimantan have widely used as wounds. The study aims to characterize the West Kalimantan water O. typhae as antibacterial and antifungal. The study of O. typhae was carried out in several stages: preparation and optimization, extraction by Quinn method, characterization and identification of bioactive compounds, and antibacterial and antifungal assay using microdilution method. The result of the proximate test showed that O. typhae powder contains high protein, namely 67.68%. Phytochemical screening results from methanol, ethyl acetate, and chloroform extracts contain alkaloids and amino acids. Methanol, chloroform, and ethyl acetate extract 1% of O. typhae showed inhibitory activity against S. aureus, E. coli, and C. albicans. The most significant inhibition value was indicated by chloroform extract 1%, where the inhibition value against S. aureus, E. coli, and C. albicans was 82±0.01%; 85.8±0.01%; 85±0.01%, respectively.

In structural designing, commonly the brickwall is only considered as a gravity load acting on the beam. On the other words, the wall in the building structure is assumed as a non-structural component. In this paper, the structural performance of a three-story building with masonry and without masonry due to seismic loads will be analyzed using pushover analysis by using the ATC 40 standard. The modeling of the building uses SeismoStruct software and assumed that the building is located in the earthquake ground acceleration region in Padang, West Sumatra. Based on the results of the analysis, the performance level of the three-story building with masonry is different compared to the building without masonry. The building with masonry as a structural component shows a better performance than without. This explains that the presence of masonry can contribute to the strength of the structure in receiving lateral loads such as earthquakes.
