Abstract

This experiment aims to: (1) to study of the effect of guano walet fertilizer and Ratu Biogen foliar fertilizeras well as their interaction on the growth and yield of tomato plants; and (2) to find proper dosage of guano walet fertilizer and proper concentration of Ratu Biogen foliar fertilizer for better growth and yield of tomato plants.The research carried out from May 2014 to July 2014, in the Village Melak Ulu RT.20 Subdistrict Melak, West Kutai. It applied Completely Randomized Design with factorial experiment 4 x 4 and five replications.  The first factor is the dosage of the guano walet fertilizer (G) consists of 4 levels, namely: no fertilizer application guano walet (g0), 10 Mg ha ̵ ¹, or 100 g of polybag ̵ ¹ (g1), 15 Mg ha ̵ ¹ or 150 g polibag ̵ ¹ (g2), 20 Mg ha ̵ ¹ or 200 g polybag ̵ ¹   (g3). The second factor is the concentration of Ratu Biogen (B) consists of 4 levels: without POC Ratu Biogen (b0), 1 ml 1 ̵ ¹ water (b1), 2 ml 1 ̵ ¹ water (b2), 3 ml 1 ̵ ¹  water (b3).Result of the research revealed that : (1) application of guano walet fertilizer affect very significantly on plant height at 14, 28, 42 days after planting, the number of fruits per plant, and weight of fruit per plant, but the effect is not significant on the days of plant flowered and days of plant harvest.  The best production is attained by the 200 g polybag-1 fertilizer guano walet (g3), namely 282,50 plant-1, In reverse, the least production is attained by without fertilizer guano walet (g0), namely 227,25 g plant ̵ ¹; (2) application of Ratu Biogen foliar fertilizer after significantly to very significantly on the plant height at 14 days after planting  and the number of fruits per plant, but the effect is no significant on the plant height at 28 and 42 days after planting, days of plant flowered, days of plant harvest, and weight of fruit per plant; and (3) interaction between guano walet fertilizer and Ratu Biogen foliar fertilizer no significantly on the plant height at 14, 28, and 42 days after planting, days of plant flowered, days of plant harvest, number of fruit per plant, and fruit weight per plant.

Abstract

This study examines the effect of supply chain digitalization on the sustainability of food micro, small, and medium enterprises (MSMEs) in Padang, Indonesia. Sustainability is conceptualized as an integrated construct comprising economic, social, and environmental dimensions. A quantitative research design was employed using survey data collected from 50 food MSMEs, which were analyzed using Partial Least Squares–Structural Equation Modeling (PLS-SEM) with SmartPLS 3.0.  The results show that supply chain digitalization has a significant positive effect on sustainability when assessed holistically, whereas its direct effects on the economic, social, and environmental dimensions individually are not statistically significant. These findings indicate that the contribution of digitalization to MSME sustainability is realized through an integrated mechanism rather than through isolated sustainability dimensions. Theoretically, this study contributes to literature by reinforcing the importance of a holistic sustainability perspective in explaining the impact of supply chain digitalization. Practically, the findings provide insights for policymakers and MSME practitioners to promote integrated digital adoption strategies that support long-term sustainable performance.

Abstract

Penelitian ini bertujuan untuk mengkaji pengaruh keberlanjutan bisnis, loyalitas konsumen,persaingan global dan strategi bisnis terhadap adopsi kecerdasan buatan (AI) dalam praktikbisnis di era digital dan globalisasi. Melalui analisis regresi linier berganda, hasil penelitianmenunjukkan bahwa dari keempat variabel yang diteliti, hanya keberlanjutan bisnis yangmemiliki pengaruh positif dan signifikan terhadap pemanfaatan AI. Sementara itu, loyalitaskonsumen, persaingan global dan strategi bisnis meskipun menunjukkan hubungan positif,tidak memberikan pengaruh yang signifikan secara statistik. Temuan ini menegaskan bahwaperusahaan yang memprioritaskan keberlanjutan lebih terdorong untuk mengadopsi AI gunameningkatkan efisiensi operasional, optimalisasi sumber daya, dan ketahanan jangka panjang.Di sisi lain, tantangan seperti keterbatasan akses teknologi, kesiapan digital yang belummerata, dan pemanfaatan AI yang belum optimal masih menghambat adopsi secara luas,khususnya di sektor usaha kecil dan menengah. Studi ini memberikan wawasan penting bagipraktisi dan pembuat kebijakan bahwa integrasi AI perlu ditopang oleh kesiapan internal,budaya organisasi, dan dukungan manajerial yang kuat. Untuk memperdalam pemahaman,penelitian lanjutan disarankan menggunakan pendekatan kualitatif atau metode campuranguna mengeksplorasi persepsi praktisi, serta meneliti dampak kausal AI terhadapkeberlanjutan bisnis, loyalitas konsumen, dan keunggulan kompetitif dalam lanskap bisnisyang semakin kompetitif dan terdigitalisasi.
