No full textABSTRAK
Biodrying merupakan teknik bioenergi yang memanfaatkan sampah untuk menghilangkan kadar air dan meningkatkan nilai kalor serta suhu sehingga berpotensi sebagai sumber energi terbarukan. Penelitian ini bertujuan untuk mengaplikasikan formulasi konsorsium mikrob dengan talk dan molase untuk proses biodrying sampah organic, mengukur pengaruh bahan pembawa terhadap efektivitas biodrying, serta mencari waktu yang optimal untuk proses biodrying. Konsorsium mikrob yang digunakan adalah Bacillus thuringiensis SAHA 12.12, Lactobacillus plantarum IN05, Rhizobium sp. RIKG, Sacharomyces cerevisiae L1, Streptomyces sp. A4J, dan Trichoderma sp. T2J dari koleksi Laboratorium Mikrobiologi IPB. Penggunaan konsorsium mikrob dapat mempengaruhi hasil biodrying limbah organik yang diukur meliputi nilai kalor, kadar air, dan penurunan bobot. Formulasi dengan molase dapat meningkatkan efisiensi biodrying (0,57), meningkatkan nilai kalor (118%-129%), kadar air (56%), penurunan bobot (34,5%), rasio C/N (32), dan suhu yang lebih tinggi dibandingkan dengan bahan pembawa lain. Formulasi dalam bentuk talek memiliki masa simpan yang lebih lama dibandingkan dengan molase. Oleh karena itu, formulasi dengan bahan pembawa molase berpotensi meningkatkan efisiensi biodrying dan talek dapat meningkatkan viabilitas masa simpan konsorsium mikrob.

Design, Service Quality, Facilities, Customer Satisfaction and Customer Preferences at Shopping Malls
Get PDFBackground: Indonesia’s economic growth has transformed consumer behavior, driving demand for malls that serve not only as retail centers but also as hubs for leisure, dining, and social interaction. In Bali, this trend is intensified by the mix of local residents and tourists with diverse expectations. The growing number of malls and rising competition highlight the need to identify key attributes that shape customer satisfaction and preferences, as misalignment may reduce competitiveness in the tourism-driven market.Purpose: This study aims to examine how design, service quality, and facilities influence customer satisfaction and preferences in modern shopping malls in Bali, and to assess the mediating role of customer satisfaction in these relationships.Design/methodology/approach: A quantitative research approach was adopted to test the conceptual framework. Data were obtained from 218 respondents who had visited three major shopping malls in Bali, selected through purposive sampling to ensure familiarity with multiple mall environments. A structured online questionnaire was using a Semantic Differential Scale captured perceptions of five latent variables: design, service quality, facilities, customer satisfaction, and customer preferences. Data were analyzed using Structural Equation Modeling based on Partial Least Squares (SEM-PLS) with SmartPLS 4.0, enabling the assessment of direct, indirect, and mediating effects in line with the Stimulus–Organism–Response (S-O-R) framework.Findings/Result: The results indicate that design and service quality significantly enhance customer satisfaction but do not directly influence customer preferences. Facilities emerge as the most influential factor, exerting a direct positive impact on preferences and an indirect effect through satisfaction. Customer satisfaction itself has a significant effect on preferences, underscoring its mediating role in linking mall attributes to behavioral intentions such as loyalty and revisit decisions.Conclusion: Customer satisfaction serves as a central bridge between mall attributes and customer preferences, underscoring the need for mall operators to invest in comprehensive facilities while maintaining high design standards and service quality to foster positive shopping experiences. In Bali’s tourism-driven retail sector, facilities that combine convenience, comfort, and leisure potential are pivotal to securing competitive advantage and encouraging repeat visits.Originality/value (State of the art): This research contributes to retail management literature by applying the Stimulus-Organism-Response (S-O-R) framework to integrate design, service quality, and facilities into a unified behavioral model explaining both satisfaction and preference formation. By focusing on a tourism-driven market, this study offers practical insights for mall operators, investors, and policymakers aiming to enhance customer experiences and strengthen brand loyalty.

Ecological Index and Aboveground Biomass Carbon Value on Burn SwampForests After Rehabilitation
Get PDFRehabilitation efforts were conducted in 2018 and 2020 to restore, maintain, and enhance forest and land functions following the 2015 fire on forest area with special purpose (KHDTK) Tumbang Nusa, Central Kalimantan. This study aims to determine the characteristics of stand structure, quantitative ecological values, aboveground biomass values, and preliminary projections of rehabilitation plant valuation in post-fire peat forest ecosystems. Study area was conducted in two rehabilitation blocks in 5 and 7 years old after rehabilitation. Vegetation analysis employed a nested sampling method, utilizing a plot size of 60 x 60 m, with Block I contain three plots (27 subplots) and Block II containing eight plots (72 subplots). Vegetation inventory and four carbon pool measurements were carried out on the understorey, seedlings, saplings, poles, and trees. The stand density value in Block I is 379 stems ha–1 with a basal area of 21.18 m2 ha–1 , while in Block II it is 503 stems ha–1 and 11.27 m2 ha–1 . The stands have good ecological value and stable vegetation, with a medium-scale species diversity level (H\u27 = 1.53–2.80), a low-scale species dominance level (D = 0.10–0.42), commonly a high species richness value (R = 3.07–6.01), and medium to high species evenness values. The composition of rehabilitation plants are similar, but Block I has a higher proportional basal area of 3.72%. The projection of aboveground carbon biomass is 70.7 ton ha–1 and 77.7 ton ha–1 , respectively. As a preliminary study, the effectiveness of the rehabilitation valuation approach can be assessed by the productivity and quantitative ecology.
The Impact of Technology on Halal Certification Intentions of MSMEs: A Gender-Based Analysis
Get PDFThis study aims to identify the main determinants influencing MSMEs in applying for halal certification through digital media, using a combination of the DeLone & McLean and UTAUT models, with a comparison between male and female MSME owners. The PLS-SEM Multi-Group Analysis (MGA) approach was employed as the evaluation method in this quantitative study, using SmartPLS 3.0. A total of 300 respondents met the required criteria. The findings show that service quality is not a major determinant for the male group. On the other hand, for the female group, system quality does not significantly influence intention to apply halal certificate. Several other constructs, such as performance expectancy, effort expectancy, social influence, and information quality, show similar results across both groups, while facilitating condition does not have a significant impact on either male or female groups. These findings provide practical implications, particularly for policymakers. The government should improve performance, ease of use and information clarity for MSMEs. For male MSMEs, focus on system quality and customer support, while for female MSMEs, extension officer assistance would be more effective in encouraging halal certificate applications
