Attitude and the Mediating Role in Online Food Delivery Continuance Intention
Get PDFBackground: The online food delivery (OFD) sector has grown rapidly in Indonesia, necessitating scholarly examination of consumer behavior beyond initial adoption to understand continuance patterns in technology-enabled consumption.
Purpose: This research aims to analyze the effects of food safety risk perception, social influence, price savings, and time savings on consumers\u27 continuance intention toward OFD services, with attitude as a mediating variable.
Method: A quantitative survey of 384 OFD users in Batam City, Indonesia, who had used the services three times in three months was conducted, and the data were analyzed using PLS-SEM.
Findings: Social influence, price savings, time savings, and food safety risk perception significantly affect attitude and continuance intention through the mediation of attitude. Food safety risk exhibits dual effects of direct negative and indirect positive effects through attitude.
Conclusions: Attitude serves as a critical mediator consistent with the Theory of Planned Behavior. OFD providers should strengthen food safety assurances, leverage social influence, emphasize efficiency benefits, and enhance positive attitudes to sustain consumer loyalty and long-term engagement.
Research implication: OFD service suppliers should strengthen consumer confidence by addressing food safety concerns, leveraging social influence, and emphasizing time and cost efficiency. Marketing and operations also improve positive consumer attitudes to support long-term engagement
Genetic Engineering of Potato (Solanum tuberosum L.) IPB CP2 Variety with OsGERLP Gene: Genetic Transformation of Potato (Solanum tuberosum L.) IPB CP2 Variety with OsGERLP Gene
No full textHigh dissolved aluminum (Al) content in acidic soil can inhibit root elongation, especially in plants sensitive to Al. The OsGERLP gene is known to be an Al tolerance gene in rice, but the role of this gene in other plants is not yet known. Introduction of the OsGERLP gene to potato cv. IPB CP2 mediated by Agrobacterium tumefaciens has been succesfully conducted. When using leaf explant, the transformation and regeneration efficiencies were 72.62 and 17.24%, respectively. However, transgene introduction using internode explant increased transformation and regeneration efficiencies to 71.3 and 87.65%, respectively. PCR-based transgene integration analysis showed that all transgenic clones contain the OsGERLP gene under the control of the 35ScaMV promoter, which was indicated by the formation of 1500 bp amplicons. Transgenic clones have been in vitro tested for Al stress using liquid MS medium with different pH and Al content. The result showed that all transgenic clones have higher tolerance to Al compared to non-transgenic plant. Morphological analysis showed that transgenic clones performed better in all parameters including plant height, total root length, number of roots, shoot and root fresh weight, shoot and root dry weight. The transgenic clones can potentially be developed as potato transgenic lines tolerant to Al toxicity.High dissolved aluminum (Al) content in acidic soil can inhibit root elongation, especially in plants sensitive to Al.

Physical Properties and Sensory Quality of Roasted Meltique Beef Injected with PalmOil
Get PDFMeltique beef was created by injecting vegetable oil emulsions into regular beef, but the high cost andoxidation susceptibility of canola oil limit its practicality. Palm oil, characterized by higher stabilityand local availability, was explored to improve physical properties and sensory qualities. The aim ofthis reserach was to analyze physical properties and sensory quality of roasted meltique beef injectedwith palm oil emulsion. Brahman cross sirloin cuts were injected with emulsions comprising oil, water,and soy protein isolate, prepared with different concentrations. The injected meats were grilled for 10minutes and assessed for pH, texture, cooking loss, and sensory attributes. Results showed that palm oilsignificantly enhanced texture and sensory properties, with palm oil at higher concentration being themost similar to Wagyu beef in marbling, tenderness, and flavor. The findings indicate that palm oil wasa cost-effective and stable alternative to canola oil for producing high-quality meltique beef, offering aviable solution for enhancing local beef products.Penelitian ini mengevaluasi penggunaan minyak sawit sebagai alternatif minyak kanola dalam produksi daging meltique, yaitu produk yang meniru marbling dan tekstur daging Wagyu. Daging meltique dibuat dengan menyuntikkan emulsi minyak nabati ke dalam daging sapi biasa. Namun, tingginya biaya dan kerentanan oksidasi minyak kanola membatasi penggunaannya. Minyak sawit yang lebih stabil dan mudah diperoleh secara lokal dieksplorasi untuk meningkatkan sifat fisik dan kualitas sensori. Potongan has luar sapi Brahman cross diinjeksi dengan emulsi yang mengandung minyak, air, dan isolat protein kedelai pada berbagai konsentrasi. Daging yang telah disuntik kemudian dipanggang selama 10 menit dan diuji untuk nilai pH, tekstur, susut masak, serta atribut sensori. Hasil menunjukkan bahwa minyak sawit secara signifikan meningkatkan tekstur dan kualitas sensori, dengan konsentrasi tertinggi menghasilkan karakteristik paling mirip dengan daging Wagyu dalam hal marbling, keempukan, dan cita rasa. Temuan ini menunjukkan bahwa minyak sawit merupakan alternatif yang lebih ekonomis dan stabil dibandingkan minyak kanola untuk menghasilkan daging meltique berkualitas tinggi, serta berpotensi meningkatkan nilai produk daging lokal

Anoplasti untuk atresia ani tipe III dengan fistula yang disertai komplikasi megakolon pada anak anjing
No full textCongenital anorectal malformations, including atresia ani, are uncommon conditions in small animals that cause gastrointestinal dysfunction. This case report describes the surgical management and outcomes of type III atresia ani in a juvenile dog. A one-month-old female mixed-breed puppy presented with severe tenesmus, progressive abdominal distension, and complete absence of normal faecal passage. Clinical examination identified an anal dimple lacking a functional opening, accompanied by a small ventral perineal fistula. Radiographic assessment confirmed type III atresia ani, characterised by a blind-ending rectal pouch located more than 1 cm cranial to the anal dimple and associated with marked megacolon. Surgical intervention was performed via anoplasty, combined with manual evacuation of the impacted faeces and temporary anal stenting using a 1-cc syringe port to maintain luminal patency. Postoperative management included broad-spectrum antibiotics, lactulose, analgesic therapy, and meticulous wound care. Although normal defaecation was restored, the patient developed tenesmus, incomplete evacuation, and faecal incontinence. These complications are associated with irreversible megacolon and anal sphincter dysfunction. Conservative therapy failed to achieve improvement, indicating the need for surgical intervention.Malformasi anorektal kongenital, termasuk atresia ani, adalah kondisi yang jarang terjadi pada hewan kecil yang menyebabkan disfungsi gastrointestinal. Laporan kasus ini menggambarkan penanganan bedah dan hasil atresia ani tipe III pada anjing muda. Seekor anak anjing betina ras campuran berusia satu bulan menunjukkan tenesmus parah, distensi abdomen progresif, dan tidak adanya pengeluaran feses normal sama sekali. Pemeriksaan klinis mengidentifikasi lesung anus yang tidak memiliki lubang fungsional, disertai dengan fistula perineal ventral kecil. Penilaian radiografi mengkonfirmasi atresia ani tipe III, yang ditandai dengan kantung rektal buntu yang terletak lebih dari 1 cm di bagian kranial lesung anus dan terkait dengan megakolon yang nyata. Intervensi bedah dilakukan melalui anoplasti, dikombinasikan dengan evakuasi manual feses yang tersumbat dan pemasangan stent anus sementara menggunakan port jarum suntik 1 cc untuk menjaga patensi lumen. Penanganan pascaoperasi meliputi antibiotik spektrum luas, laktulosa, terapi analgesik, dan perawatan luka yang teliti. Meskipun buang air besar normal telah pulih, pasien mengalami tenesmus, evakuasi tinja yang tidak tuntas, dan inkontinensia tinja. Komplikasi ini dikaitkan dengan megakolon ireversibel dan disfungsi sfingter anus. Terapi konservatif gagal memberikan perbaikan, menunjukkan perlunya intervensi bedah

AUTONOMY-SUPPORTIVE OR AUTONOMY-THWARTING: THE ROLE OF PARENTING PROFILE IN PREDICTING SELF-REGULATED LEARNING IN INDONESIAN UNIVERSITY STUDENTS: Autonomy-Supportive or Autonomy-Thwarting: Peran Profil Pengasuhan sebagai Prediktor Regulasi Diri dalam Belajar Mahasiswa Indonesia
No full textFor the past three decades, self-regulated learning (SRL) has been a key focus in educational psychology, with both parenting and teaching strategies playing crucial roles. This study aims to examine the role of Helicopter Parenting (HP) on Indonesian college students’ SRL.Sampling was conducted using a non-probability approach, specifically employing a convenience sampling technique. A survey method was used to measure the perceptions of 256 Indonesian college students regarding their parents’ parenting profiles using the Helicopter Parenting Instrument – Short Version (HPI-S) and their SRL using the Motivated Strategies for Learning Questionnaire (MSLQ). The results indicate that HP significantly contributes to the development of SRL among Indonesian college students. This finding contradicts most previous studies. However, further analysis suggests that a significant portion of SRL variability remains unexplained by HP and may be influenced by other factors. Culture emerges as a crucial factor deserving attention and is discussed as a key influence on the outcomes of this research
