Abstract

Infeksi Saluran Pernapasan Akut (ISPA) adalah penyakit pada saluran pernapasan atas dan bawah yang disebabkan oleh virus atau bakteri. Faktor penyebab utamanya meliputi polusi udara, sanitasi lingkungan yang buruk, serta kurangnya pengetahuan dan pola hidup tidak sehat. Penelitian ini bertujuan mengetahui tingkat pengetahuan dan sikap pasien terhadap ISPA dan pengobatannya, serta hubungannya di Klinik x Padang. Penelitian ini bersifat deskriptif analitik dengan teknik accidental sampling dan menggunakan kuesioner, dianalisis dengan uji chi-square. Hasil menunjukkan mayoritas pasien memiliki pengetahuan sangat baik (72,4%), diikuti baik (21,4%) dan kurang baik (6,1%). Sementara itu, sikap pasien sebagian besar tergolong baik (64,3%) dan sangat baik (35,7%). Namun, uji statistik menunjukkan tidak terdapat hubungan signifikan antara tingkat pengetahuan dan sikap terhadap ISPA. Persentase tertinggi ditemukan pada kategori pengetahuan sangat baik (48 responden/67,6%) dan sikap baik (48 responden/76,2%). Meskipun pengetahuan tinggi, hal ini tidak selalu diikuti oleh sikap yang sebanding. Faktor lain kemungkinan memengaruhi pembentukan sikap pasien terhadap ISPA dan pengobatannya.Abstract ditulis dalam bahasa Inggris dan bahasa Indonesia (kecuali artikel yang ditulis dalam bahasa Inggris) yang berisikan isu-isu pokok, tujuan penelitian, metode/pendekatan dan hasil penelitian..

Abstract

This study aims to analyze the influence of Word of Mouth (WOM) and Influencer Marketing on the purchasing decision of eyeglasses at Optik Jaya, Padang City. A quantitative approach was employed using a survey method involving 76 active customers as respondents. Data were analyzed using multiple linear regression to assess both simultaneous and partial effects of the independent variables. The findings indicate that both Word of Mouth and Influencer Marketing have a positive and significant effect on purchasing decisions. WOM contributes through interpersonal information credibility, while Influencer Marketing influences through the attractiveness and social power of public figures on social media. Together, these variables account for 37.4% of the variation in consumer purchasing decisions. These results provide practical implications for optical businesses in designing marketing strategies that integrate interpersonal and digital communication to enhance customer loyalty and sales volume.

Abstract

Penelitian ini bertujuan untuk membandingkan kinerja metode Weighted Aggregated Sum Product Assessment (WASPAS) dan metode VIsekriterijumsko KOmpromisno Rangiranje (VIKOR) dalam menentukan mobil Low Cost Green Car (LCGC) terbaik. Studi kasus dilakukan pada showroom mobil di Kota Padang dengan mempertimbangkan delapan kriteria penilaian, yaitu harga OTR, kapasitas mesin, konsumsi bahan bakar,tenaga max, torsi max, desain eksterior, desain interior dan akselarasi. Metode WASPAS digunakan untuk memperoleh peringkat kendaraan melalui kombinasi model penjumlahan dan perkalian terbobot, sedangkan metode VIKOR difokuskan pada kompromi solusi berdasarkan jarak terhadap alternatif ideal positif dan negatif. Pengujian akurasi dilakukan dengan menggunakan korelasi Rank Spearman untuk mengukur tingkat kesesuaian hasil peringkat masing-masing metode dengan preferensi konsumen aktual. Hasil penelitian menunjukkan bahwa metode VIKOR memiliki tingkat akurasi yang lebih tinggi dibandingkan metode WASPAS, dengan nilai koefisien korelasi Rank Spearman sebesar 0,9761 yang termasuk kategori sangat kuat. Temuan ini mengindikasikan bahwa metode VIKOR lebih efektif digunakan dalam sistem pendukung keputusan untuk pemilihan mobil LCGC yang sesuai dengan kebutuhan konsumen di showroom Kota Padang.

Abstract

This study aims to determine the influence of social media advertising language on sales improvement at Optik Jaya and Dian Optikal in Padang City. The background of this research is based on the phenomenon that many optical business owners have utilized social media as a promotional tool, but have not yet optimized the use of persuasive and emotional advertising language. This research uses a quantitative method with a survey approach. The sample consists of 100 respondents who are customers or social media followers of the two optical stores. Data were collected using a closed-ended questionnaire with a Likert scale and analyzed using simple linear regression. The results show that social media advertising language has a significant influence on sales improvement, with an R² value of 0.534. This means that 53.4% of the variation in sales increase is influenced by advertising language, while the remaining 46.6% is influenced by other factors. The findings indicate that using advertising language that is attractive, emotional, and culturally relevant can increase consumer interest and buying actions.

Abstract

Indonesia has a high level of noodle consumption, including fresh noodles, which are popular for their practicality and distinctive taste. Fresh noodle production presents a promising business opportunity for small-scale entrepreneurs but still faces challenges in managing production costs and setting appropriate selling prices. This study aims to analyze the Break Even Point (BEP) in fresh noodle production to determine the minimum production quantity required to avoid losses. The research was conducted in Kamang Sub-district, Agam Regency, West Sumatra, from September to December 2024 using a survey method through direct observation and structured interviews with a group of women farmers. The results showed that the total fixed costs amounted to Rp 25,353,000 per year, variable costs were Rp 7,175 per pack, and the selling price was Rp 10,000 per pack. The business break-even point is reached at the sale of 8,974 packs or equivalent to Rp 89,586,572 per year. These findings are expected to serve as a practical reference for small business owners in setting production targets, selling prices, and cost management strategies to maintain sustainable operations.

Abstract

Safety risk surveillance at nuclear facilities is an important element in ensuring the protection of workers, the public, and the environment from radiation hazards. The Nuclear Power Supervisory Institution manages large data related to nuclear safety risk surveillance. However, this very large and diverse volume of data causes difficulties in adequate processing and analysis, thus hampering the speed and accuracy of supervisory decision making. The main obstacle faced is data management that is still manual and less integrated so that the risk monitoring process becomes less efficient. Therefore, this research designs a website-based Decision Support System (DSS) with the Analytic Hierarchy Process (AHP) method to assist the decision-making process that is more objective, accurate, and based on risk priorities in nuclear safety. The results showed that the use of the AHP method in DSS was able to provide priority weights for risk criteria in an objective and structured manner. Consistency Ratio (CR) of 0.0066 shows a good level of assessment consistency. This system facilitates data visualization and presents safety risk inspection priority recommendations effectively through an interactive dashboard. The designed DSS is expected to improve the efficiency and effectiveness of nuclear safety risk monitoring at the Nuclear Power Supervisory Institution.
