PERSEPSI PERNIKAHAN PADA PEREMPUAN DEWASA MUDA SEBAGAI IMPLIKASI DARI FENOMENA FATHERLESS
Authors: Aulia Adis Prita , Santoso Meilanny Budiarti , Apsari Nurliana Cipta
Published: February 2025

Fatherless-ketiadaan ayah, merupakan sebuah fenomena ketidakhadiran sosok ayah yang berperan dalam pengasuhan anak, baik secara fisik maupun secara psikologis. Perempuan dewasa muda adalah ia yang berada pada rentang usia 20 - 30 tahun yang dalam perkembangan psikososialnya memiliki kecenderungan untuk membangun intimacy, khususnya dengan lawan jenis. Ketidakhadiran peran ayah dapat berpengaruh signifikan terhadap perkembangan sosial dan emosional anak perempuan yang kemudian memengaruhi persepsi mereka terhadap hubungan romantis dengan lawan jenis saat dewasa, salah satunya pernikahan. Tujuan penulisan artikel ini adalah untuk menggambarkan persepsi pernikahan pada perempuan dewasa muda sebagai implikasi dari fenomena fatherless. Penelitian ini dilakukan menggunakan metode kualitatif deskriptif dengan wawancara mendalam pada beberapa informan. Hasil penelitian menunjukkan bahwa persepsi terkait pernikahan pada perempuan dewasa muda cenderung negatif sebagai akibat dari fenomena fatherless. Sebagian perempuan yang mengalami fatherless cenderung mengasosiasikan pernikahan dengan konflik, ketidakstabilan, dan ketidakharmonisan, yang akhirnya memengaruhi keputusan mereka untuk menunda pernikahan atau menghindarinya. Ketidakharmonisan dalam pernikahan orang tua informan mengakibatkan terciptanya pandangan yang sangat selektif dalam memilih pasangan, serta cenderung memilih untuk tidak menikah jika tidak menemukan pasangan yang dianggap sesuai dengan harapan.  Fatherlessness is a phenomenon of the absence of a father figure who plays a role in raising children, both physically and psychologically. Young adult women are those who are in the age range of 20 - 30 years who, in their psychosocial development, tend to build intimacy, especially with the opposite sex. The absence of a father's role can have a significant effect on girls' social and emotional development, which then affects their perception of romantic relationships with the opposite sex as adults, one of which is marriage. This article aims to describe the perception of marriage in young adult women as an implication of the fatherless phenomenon. This research used a descriptive qualitative method with in-depth interviews with several informants. The study results show that the perception related to marriage in young adult women tends to be negative due to the fatherless phenomenon. Some women who experience fatherlessness tend to associate marriage with conflict, instability, and disharmony, which ultimately influences their decision to postpone marriage or avoid it. Disharmony in the marriage of informants' parents results in a very selective view in choosing a partner and tends to choose not to get married if they do not find a partner who is considered to be under expectations.

This research proposes to determine the effect of (1) customer satisfaction on brand image religiosity, (2) brand image religiosity on customer loyalty, (3) customer satisfaction on customer loyalty, and (4) customer satisfaction on customer loyalty towards brand image religiosity as an intervening variable. The research was conducted on 400 Bank Aceh Syariah (Sharia bank) customers using a questionnaire instrument. The research used a quantitative method using the SEM PLS model and analyzed by the Warp PLS analysis tool. The research results proved that (1) there was a direct effect of customer satisfaction on brand religiosity image of 0.866. (2) The direct effect of brand religiosity image on customer loyalty was 0.305. (3) The direct effect of customer satisfaction on customer loyalty was 0.845. (4) The indirect effect of customer satisfaction on customer loyalty was 0.315. Bank Aceh Syariah might focus on customer satisfaction, customer loyalty, and brand image religiosity; these three things have a relationship in marketing for the development of Islamic banking, the sustainability of Islamic banking, and the success of banking businesses in the future. In addition, those three things must be grounded on maqasyid sharia in the form of Ar-Rawaj; Al-Wudhuh, Al-Hifzu, Al-Sabtu, and Al-Adlu to avoid principles that are prohibited in religion. Penelitian ini bertujuan untuk mengetahui pengaruh (1) kepuasan nasabah terhadap religiusitas citra merek, (2) religiusitas citra merek terhadap loyalitas nasabah, (3) kepuasan nasabah terhadap loyalitas nasabah, dan (4) kepuasan nasabah terhadap loyalitas nasabah dengan religiusitas citra merek sebagai variabel intervening. Penelitian dilakukan terhadap 400 nasabah Bank Aceh Syariah dengan menggunakan instrumen kuesioner. Penelitian menggunakan metode kuantitatif dengan menggunakan model SEM PLS dan dianalisis dengan alat analisis Warp PLS. Hasil penelitian membuktikan bahwa (1) terdapat pengaruh langsung kepuasan nasabah terhadap citra religiusitas merek sebesar 0,866. (2) Pengaruh langsung citra religiusitas merek terhadap loyalitas nasabah sebesar 0,305. (3) Pengaruh langsung kepuasan pelanggan terhadap loyalitas pelanggan sebesar 0,845. (4) Pengaruh tidak langsung kepuasan nasabah terhadap loyalitas nasabah sebesar 0,315. Bank Aceh Syariah dapat memfokuskan diri pada kepuasan nasabah, loyalitas nasabah, dan brand image religiusitas, karena ketiga hal tersebut memiliki keterkaitan dalam pemasaran untuk pengembangan perbankan syariah, keberlangsungan perbankan syariah, dan keberhasilan bisnis perbankan di masa yang akan datang. Selain itu, ketiga hal tersebut harus dilandasi dengan maqasyid syariah berupa Ar-Rawaj; Al-Wudhuh, Al-Hifzu, Al-Sabtu, dan Al-Adlu agar terhindar dari prinsip-prinsip yang dilarang agama.

Environmental politics as part of social science has very broad aspects, one of which is the gender aspect. In fact, women can actively work in the public sector because it is important to balance gender roles between men and women. Cooperative decision making between men and women is a reflection of gender equality in forest resource management. This research analyzes the role of gender in decision making for forest resource management based on environmental politics in Pinang Jaya Village, Talang Mulya Village, and Cilimus Village around the Way Betung watershed. The data analysis used is descriptive quantitative. The research results show that gender roles in making decisions on forest resource management such as land preparation, seeding, planting, maintenance, harvesting and security activities are known to be dominated by husbands with an average percentage (77%), while women only dominate. in marketing activities with a percentage of (9%). The high role of men is caused by patriarchal cultural factors which still assume men have full access and good knowledge in managing forests. The correlation between job characteristics and decision making in forest resource management such as land preparation, seeding, planting, maintenance, harvesting, marketing and security is known to have a significant relationship. Meanwhile, there are still variables that are not correlated with the correlation between age, gender and education. Based on environmental political aspects, there is a need for intensive understanding and training regarding gender balance for site leaders because it has been proven that gender is correlated with the sustainability of natural resources.

The paper deals with monitoring the quality of a shaped part of a mould made from H13 tool steel using additive manufacturing. The shaped part of the mould is a key element in the casting of aluminium alloys by high pressure die casting (HPDC) technology and has a major influence on achieving the desired quality of the casting. This paper presents an evaluation methodology which includes the results of surface quality analysis and dimensional accuracy and stability of additively manufactured parts. These analyses were carried out from the production of the mould part to its application in the foundry operating conditions. The comprehensive analyses offer an overall view of the changes caused by individual technological operations. These operations are additive manufacturing, heat treatment, machining, and final coating before implementation into the operating conditions of the foundry. The paper also describes monitoring the quality of the mould part in regular cycles during the production of aluminium castings. This methodology and the results provide new insights in the field of engineering metallurgy.
Companion animal veterinary personnel have occupational risk for tularemia and One Health role for tularemia prevention in Kansas
Authors: KuKanich Kate S. , Mulcahy Ellyn R. , Petro Erin M.
Published: February 2025

OBJECTIVE

To learn the knowledge, attitudes, and practices of veterinarians and technicians in Kansas regarding the occupational risk of tularemia, personal protection, patient diagnosis and management, zoonotic risk communication, and public health reporting.

METHODS

Kansas veterinarians and technicians serving cats and dogs completed an online survey between June and September 2024.

RESULTS

The survey was completed by 109 veterinarians and 19 technicians. Forty-three percent (47 of 109) of veterinarians reported diagnosing tularemia in cats and 13% (14 of 109) in dogs. Seven percent (8 of 109) of veterinarians reported having had tularemia. When performing procedures with a high risk of exposure, such as lancing abscesses in tularemia suspects, glove use was 100% but additional personal protective equipment was inconsistent, including eye protection (81 of 116 [70%]) and surgical face mask (69 of 116 [59%]). Antibody titer and PCR were common diagnostics, but 42% (26 of 62) of veterinarians reported never submitting a confirmatory test, with owner finances being the primary hurdle. Veterinarians and technicians have inconsistent knowledge about reporting regulations, but 91% (58 of 64) discuss tularemia’s public health risk with pet owners.

CONCLUSIONS

Veterinarians are not only diagnosing tularemia in their patients but also contracting the disease themselves. Education should be targeted toward diagnostics, protection, and reporting.

CLINICAL RELEVANCE

Veterinary personnel play an essential One Health role in the prevention and control of tularemia in Kansas through environmental tick and wildlife management, diagnosis and treatment of sick pets, and education about transmission and protection precautions for people. Designating tularemia as reportable in animals would allow determination of disease trends and more rapid public health follow-up.

Published: February 2025

Introdução: Na clínica médica de pequenos animais a Malasseziose é uma enfermidade encontrada rotineiramente, sendo até o momento, a espécie Malassezia pachydermatis o agente etiológico mais comum. A proliferação exagerada da Malassezia spp contribui para o aumento do prurido e está frequentemente associada a uma causa primária como as dermatopatias alérgicas, endocrinopatias, distúrbios de ceratinização ou em associação a antibioticoterapia prolongada. A dermatite atópica canina (DAC) é uma dermatose alérgica de pele, de caráter crônico, genético, de origem multifatorial, pririginosa o que resulta em lesões na pele. O objetivo do presente trabalho é relatar o caso de um cão da raça Shih tzu diagnosticado com malasseziose secundária a dermatite atópica canina.  Relato do caso: Cadela da raça Shih tzu, com 8 anos e 5 meses, pesando 7,3kg, proveniente do município de Friburgo com relato de prurido intenso, dermatite desde os dois anos de idade e otite de repetição. Através do histórico, anamnese, sinais clínicos, exames complementares e diagnóstico diferencial do prurido, concluiu-se que a cadela apresentava DAC induzida por alimento e alérgenos ambientais e malasseziose secudária. Discussão: A dermatite atópica canina se origina de forma multifatorial, podendo envolver fatores genéticos e ambientais, o que resulta em lesões cutâneas pruriginosas e inflamatórias. O tratamento multimodal normalmente perdura por toda a vida do animal e os resultados favoráveis se devem ao acompanhamento periódico do médico veterinário. Conclusão: A enfermidade é de grande importância na clínica médica de pequenos animais sendo necessário mais estudos sobre seu diagnóstico, já que é difícil de ser realizado por se confundir facilmente com outras dermatopatias.

Musculoskeletal pain (MSP) is highly prevalent and impacts productivity, leading to significant economic and social burdens. Combining non-steroidal anti-inflammatory drugs (NSAIDs) with Vitamin B supplements has shown promising results in reducing MSP more effectively than NSAIDs alone. This meta-analysis aimed to assess the efficacy and safety of NSAIDs with Vitamin B, paving the way for future studies on the potential of Vitamin B as an add-on therapy for various MSP conditions. The relevant records up to June 2024 were retrieved from PubMed, Scopus, Web of Science, and the Cochrane Library. Two independent reviewers extracted data from eligible studies, including baseline data and information about the safety and efficacy of mixture regimens compared to using NSAIDs alone. Around 2,326 records were collected from four databases, excluding 189 duplicates. After screening titles and abstracts, 15 records were assessed for eligibility, resulting in eight included articles. Of these, six provided sufficient data for analysis, which compared NSAIDs alone vs. NSAIDs + Vitamin B for musculoskeletal pain, osteoarthritis, back pain, and cervical sprains. NSAIDs + Vitamin B significantly reduced visual analogue scale (VAS) pain scores (MD: -0.85 [95%CI: -1.33, -0.36; P = 0.0007]). Adverse events were lower for NSAIDs + Vitamin B but not statistically significant (RR: 0.77 [95%CI: 0.51, 1.18; P = 0.23]). Combining NSAIDs with Vitamin B supplements showed promising benefits for musculoskeletal pain, offering more effective pain relief, earlier therapy termination, and improved functionality as compared to NSAIDs alone.

Improved Concecutive Modal Pushover (ICMP) method is proposed to improve the conventional Pushover in estimating earthquake demands on tall buildings. This method accounts for inelastic material properties and interaction between vibration modes. The incremental displacement at the building roof used in each stage of the pushover analysis is modified based on the displacement contribution of each mode. This study proposes an improved of the existing ICMP method by modifying the vibration mode variations in the pushover analysis. The performance of the modified ICMP method is verified against a wide variety of modes to determine the lateral forces of various building conditions. The results obtained from the modified ICMP method are compared with the results from Nonlinear Response History Analysis (NLHRA), and conventional pushover analysis, as well as the original ICMP method. The comparison shows that the results obtained from the modified ICMP method with mode variation of S1 (100% M), S2 (90% M1 + 10% M2), and S3 (80% M1 + 20% M3), are closer than the original ICMP using 100% participation of modes 1, 2, and 3. The modified ICMP yields an underestimate results against the original ICMP in the context of displacement response by not more than 30%

Soil is an important factor in construction. one of the important soil parameters is the unconfined compressive test strength where the unconfined compressive test strength value is the stress value at the maximum strength that can be supported by an object before experiencing damage caused by compressive forces. One of the factors that influences the strength value of the unconfined compression test is water. This research aims to find a decrease in the strength value of the free compression test caused by immersion. This research is based on standards from ASTM D698, ASTM D1557, SNI 1744, ASTM D2166, ASTM D2216, dan ASTM D4318. The highest compressive test strength values ​​for compaction are in dry conditions and modified compaction types. And it has a significant decrease in compressive test strength value after soaking. The lowest compressive test strength value is found in dry conditions and standard compaction after soaking. The higher the water content after passing the optimum water content, the soil experiences a large decrease in the unconfined compressive strength test value.

Soil compaction is one of the methods used to improve soil quality, such as increasing shear strength and load-bearing capacity, reducing compressibility and permeability of soil, and minimizing volume changes due to variations in moisture content. Soil compaction requires soil lift thickness according to standards, typically around 100-200 mm. If compaction is done with an inappropriate soil lift thickness, the effectiveness of the compaction may be compromised. Testing results show that compaction with a 20 cm layer of soil yields cohesive value of 0.7 kg/cm2 and shear angle values of a 23.2°, with a shear strength value of 72.57 kPa Compaction with a 40 cm layer of soil yields cohesive value of 0.36 kg/cm2 and shear angle values of 22.6°, with a shear strength value of 39.21 kPa. Comparing the results from these two different thicknesses shows that compaction at 40 cm results in significantly reduced values compared to the 20 cm thickness. Therefore, it is crucial to ensure proper thickness during field compaction to avoid compromising the structure being built.

Pemadatan tanah merupakan salah satu metode peningkatan kualitas tanah, seperti kenaikan kuat geser dan kapasitas menahan beban, pengurangan kompresibilitas dan permeabilitas tanah, dan mengurangi perubahan volume akibat perubahan kadar air. Pemadatan tanah memiliki ketebalan lapisan tanah yang sesuai standar yaitu sekitar 100-200 mm. Jika dilakukan pemadatan dengan ketebalan yang tidak sesuai maka hasil pemadatan menjadi kurang efektif. Hasil pengujian pemadatan dengan ketebalan lapisan tanah 20 cm menghasilkan nilai kohesi sebesar 0,7 kg/cm2 dan sudut geser sebesar 23,2°, dengan nilai kuat geser sebesar 72,57 kPa. Pemadatan dengan ketebalan lapisan tanah 40 cm mendapatkan nilai kohesi sebesar 0,36 kg/cm2 dan sudut geser dalam sebesar 22,6°, dengan nilai kuat geser sebesar 39,21 kPa. Dari hasil yang didapatkan dari 2 jenis ketebalan tanah yang berbeda dapat dilihat bahwa pemadatan pada 40 cm menghasilkan nilai yang cukup menurun dibanding ketebalan 20 cm. Sehingga pemadatan yang dilakukan pada ketebalan yang 40 cm kurang efektif, dan perlu diperhatikan pada saat pemadatan dilakukan di lapangan agar tidak membahayakan struktur yang dibangun.
STUDI ANALISIS DAYA DUKUNG FONDASI DANGKAL PADA LERENG GALIAN

Published: February 2025

This study aims to analyze the bearing capacity of shallow foundations on excavation slopes using computer programs with numerical analysis methods and manual calculations using the Meyerhof method to calculate bearing capacity. Numerical analysis methods are used to model the complex interactions between shallow foundations and the surrounding soil, allowing for the simulation of various field conditions and soil parameters to provide an accurate depiction of the behavior of shallow foundations. The numerical analysis results indicate that the steeper the slope, the lower the bearing capacity of the foundation due to the reduced stability of the supporting soil. Conversely, if the distance of the foundation from the slope increases, the bearing capacity increases as the influence of the slope on the foundation's stability diminishes. Manual calculation results, compared with those obtained using computer programs, show that both methods yield similar results, indicating that manual methods can still be reliable for initial estimations. The conclusion of this study emphasizes the importance of considering slope factors and the distance of the foundation from the slope in the planning and design of shallow foundations in excavation slope areas to ensure adequate stability and bearing capacity for building construction.
Abstrak
Penelitian ini bertujuan untuk menganalisis daya dukung fondasi dangkal pada lereng galian menggunakan program komputer dengan metode analisis numerik dan perhitungan manual menggunakan metode meyerhof untuk menghitung daya dukung. Metode analisis numerik digunakan untuk memodelkan interaksi kompleks antara fondasi dangkal dan tanah di sekitarnya, memungkinkan simulasi berbagai kondisi lapangan dan parameter tanah sehingga memberikan gambaran akurat mengenai perilaku fondasi dangkal. Hasil analisis numerik menunjukkan bahwa semakin curam kemiringan lereng, daya dukung fondasi semakin kecil karena penurunan stabilitas tanah yang mendukung fondasi. Sebaliknya, jika jarak fondasi dari lereng semakin jauh, daya dukungnya semakin besar karena pengaruh lereng terhadap stabilitas fondasi berkurang. Hasil perhitungan manual sebagai perbandingan dengan hasil perhitungan menggunakan program komputer menunjukkan bahwa kedua metode tersebut tidak jauh berbeda, menunjukkan bahwa metode manual masih dapat diandalkan untuk estimasi awal. Kesimpulan penelitian ini menekankan pentingnya mempertimbangkan faktor lereng dan jarak fondasi dari lereng dalam perencanaan dan desain fondasi dangkal di area lereng galian untuk memastikan kestabilan dan daya dukung yang memadai bagi konstruksi bangunan.

Representasi Aksara Siddham sebagai Dewa-Dewi Buddha Pelindung dalam Zodiak Jepang
Authors: Anugrahani Safila , Purnomo Antonius R. Pujo
Published: February 2025

Aksara Siddham, sistem penulisan tertua yang berasal dari India dan digunakan dalam Buddhisme untuk mewakili suara-suara sakral, berfungsi sebagai representasi dewa-dewi pelindung dalam zodiak Jepang. Dengan menerapkan teori representasi dari Stuart Hall (1997), yang mengemukakan ide bahasa sebagai media kreasi makna dalam budaya, artikel ini bertujuan menjelaskan bagaimana aksara Siddham diadaptasi oleh masyarakat Jepang untuk mempertahankan tradisi nenek moyang mereka dalam aspek spiritual terutama dalam sistem kalender zodiak mereka. Studi ini menggunakan pendekatan deskriptif kualitatif menurut Abdussamad (2021) dengan metode studi pustaka untuk menganalisis hubungan simbolik antara aksara Siddham dan dewa-dewi Buddha. Hasil dari sajian tabel dan data peneliti membuktikan bahwa aksara Siddham, selain sebagai alat komunikasi religius, berfungsi sebagai simbol budaya yang mengakar kuat dalam masyarakat Jepang yang berfungsi menghubungkan tiap individu dengan dewa pelindung spiritual Buddhisme sesuai dengan tahun kelahirannya. Hal ini menyoroti pentingnya aksara Siddham dalam memperkuat identitas religius Jepang melalui simbolisme dan makna budaya.

Published: February 2025

This quasi-experimental study assessed the effectiveness of the Montessori method on early literacy skills among Group B students at TK Bahtera Bukit Zaitun and compared outcomes with conventional teaching methods. The sample consisted of 28 students aged 5–6, divided into experimental and control groups. The Montessori apparatus included large movable alphabets, sandpaper letters, and reading boxes, with the study conducted from April to June 2024. Pretests and post-tests measured alphabet knowledge, phonemic awareness, and grapheme-phoneme correspondence. Results showed significant improvement in the experimental group, with median scores increasing from 2.5 to 3.8 and mode from 1.4 to 3.8. The Mann-Whitney U test yielded a p-value of .003, and the gain score analysis showed a p-value of 0.001 with a biserial rank coefficient of .7, confirming the Montessori method's effectiveness. It is recommended that kindergarten teachers incorporate phoneme-based approaches in literacy instruction, as these methods proved particularly helpful for students struggling with alphabet memorization.
Evaluating objectivity in reflective writing assessments: A comparative study of Niemi’s and Moon’s approaches
Authors: Gangwani Nonita , Khaliq Farah , Singh Satendra
Published: February 2025

Objectives:

Reflective writing is a key component of competency-based medical education, promoting critical thinking, professionalism and the integration of knowledge into clinical practice. However, assessing reflective writing remains inherently subjective. This study aimed to evaluate student reflections from two MBBS batches using two different assessment approaches and to determine if there were differences in grading between the two methods.

Materials and Methods:

We conducted a retrospective audit of reflections from MBBS students in the 2021 and 2022 batches, focusing on their perspectives regarding the doctor-patient relationship, a crucial part of the ethics module. Following an instructional session on Rolfe’s model of reflection, conducted 1 week after the attitude, ethics and communication session, reflections were graded using Niemi’s and Moon’s approaches. Reflections categorised as ‘diffuse’ by Niemi and those receiving grades E or F by Moon were considered below standard.

Results:

In the 2021 batch (n = 156), 16.02% of reflections were categorised as ‘diffuse’ according to Niemi, with 55.76% receiving grades A and B, and 10.24% receiving grades E and F by Moon. In the 2022 batch (n = 146), 11.64% were classified as ‘diffuse’, 53.41% received grades A and B, and 4.78% received grades E and F. Analysis revealed significant overlap in grades using Moon’s approach. No statistically significant difference was found between the assessments of the two batches using Niemi’s approach, suggesting greater reliability of this method.

Conclusion:

Our study supports the use of Niemi’s approach for a more objective evaluation of reflections. The findings highlight the need for refining assessment criteria and minimising interrater variability to ensure more accurate and equitable evaluations.
Electroencephalographic power spectrum and intersubject correlation on acoustic stimulation with modes of Indian music: A randomised controlled trial
Authors: Kunikullaya U Kirthana , Sasidharan Arun , Muradi Vijayadas , Kunnavil Radhika , Goturu Jaisri , Murthy N. S.
Published: February 2025

Objectives:

There is variation in the level of engagement among individuals during any sensory experience, including listening to music. This current randomised controlled triple-blind study employed Indian music to understand electroencephalogram (EEG) based inter-brain synchronisation.

Materials and Methods:

Four groups (three music interventions: mode or raga Miyan ki Todi, Malkauns and Puriya and one control group) were compared, with 35 participants in each group. EEG power spectrums before intervention (BI), during intervention (DI) and after intervention (AI) acoustic were analysed for correlated components (C1, C2 and C3), and scores of Inter-subject correlation (ISC).

Results:

Left frontal gamma power increased with raga Malkauns DI. Raga Miyan ki Todi showed a frontal increase in beta1 power, and raga Puriya showed a decrease in right frontoparietal delta power AI. The raga Malkauns and Miyan ki Todi groups showed decreased C1 (globally distributed low-frequency activity) and increased C2 (posteriorly dominant alpha-beta1 activity) power. Raga Puriya showed a weak decrease in C1 and ISC scores and a marginal drop in C3 (peripherally dominant broad-band activity) AI.

Conclusion:

The findings demonstrate specific mode-dependent correlated EEG components that persist after the listening period. The short-term effects were postulated due to default-mode network activity and autobiographical memory. Overall, this study adds to our understanding of the effects of Indian music on the brain.
