Abstract

Peranggi chili (Capsicum annuum L. var. chinensis) is a local chili variety with high spiciness and a distinctive aroma from West Kalimantan; however, its quality, including vitamin A content, are not known yet. This study aimed to assess the quality, including the vitamin A content, of Peranggi chili. The experimental design was a Completely Randomized Block Design (RCBD), with sampling time as blocks and different markets as treatments, each with three replications. The measurements included weight, length, diameter fruit, peduncle length, peduncle weight, color, namely (L, a, b) and lastly vitamin A content. Data were analyzed using SAS with the ANOVA model for RCBD, followed by the Least Significant Difference (LSD) test if the treatments were significant. Multiple regression analysis was applied to identify the quality variables that determine vitamin A content. The weight, length, and diameter fruit of Peranggi chili was smaller in shape and size compared to other Capsicum annuum varieties. The size pranggi chili varietdD. Vitamin A content also varies and was more influenced by the maturity level of the chili (a and L values). The resulting data can serve as a basis for grading the quality of Peranggi chili, including its vitamin A content.

Abstract

Artificial intelligence (AI) has advanced rapidly over the past two decades, creating opportunities to address ecological and agricultural challenges by integrating computational methods with genetics. This study aims to map the scientific landscape of research at the intersection of AI, insect population genetics, and coffee agroecosystems. A bibliometric analysis was conducted using the Scopus database, covering publications from 1978 to 2025 and employing co-occurrence, co-authorship, centrality, and co-citation analyses supported by VOSviewer for visualization. The results show a significant growth in publications since 2010, with the United States and Brazil as leading contributors, while collaborations among influential authors and institutions have shaped three main clusters: ecology and agroecosystem management, insect–pest interactions and biological control, and genetics with molecular approaches to plant metabolism. The co-citation network further highlights the integration of pest ecology, biodiversity conservation, and the economic value of pollinators as central themes. These findings indicate that AI–genetics integration is increasingly pivotal for sustainable coffee management, with future research directions emphasizing predictive modeling of pest and pollinator dynamics under climate variability, alongside investigations into soil microbiomes and pollinator health to enhance resilience in coffee production systems.

Abstract

Indonesia's tropical climate encourages its people to consume cold beverages as a way to stay refreshed. One of the main components of cold beverages is ice. The quality and hygiene of ice used by vendors usually neglect the quality of ice production and handling, posing potential health risk. This study aims to evaluate the safety of ice sold by vendors around Prasetiya Mulya University. Ice cube samples were collected from seven vendors using a plastic cup and taken directly to the laboratory. The study employs both qualitative and quantitative approaches. Qualitative data were obtained through interviews with employees or business owners to understand vendor characteristics and hygiene practices during operations. Quantitative data include three main tests: Total Plate Count (TPC), Most Probable Number (MPN), and environmental monitoring. The results provide evidence-based insights to support public health initiatives and promote the sustainability of informal food businesses around Prasetiya Mulya University. The study revealed that all ice samples from seven locations did not meet the microbiological standards by SNI 3839:2019. All samples had microorganism counts greater than 10² CFU/mL, and estimated coliform bacteria counts ranged from 23 to ≥2400 MPN/100 mL. The confirmation of Escherichia coli presence in four out of seven samples, indicates fecal contamination. Sanitation evaluations using EB petrifilm also showed the ineffectiveness of ice scoop cleaning at several locations. These findings highlight the urgent need for improved hygiene practices among vendors. They require regular food safety training, enforcement of regulatory standards, and sourcing ice from certified suppliers.

Abstract

Fusarium species are destructive plant pathogens responsible for severe crop losses thereby posing a critical threat to global food security. Sustainable strategies to control Fusarium-induced diseases are urgently needed due to limitations of synthetic fungicides. This study investigated the interaction of phytochemicals from potato (Solanum tuberosum), cassava (Manihot esculenta), and purple yam (Dioscorea alata) with three Fusarium proteins: LaeA, Pep2, and VeA. Protein structures were modeled and validated using stereochemical analyses, followed by molecular docking with representative metabolites, including pyrogallol, cyclogallipharaol, scopoletin, linamarin, cyanidin-3-glucoside, and peonidin-3-glucoside. Docking results showed that potato metabolites exhibited moderate binding activity, cassava metabolites displayed broader inhibitory potential, and purple yam anthocyanins demonstrated the strongest affinities (–6.7 to –7.4 kcal/mol) through multiple hydrogen bonds, hydrophobic contacts, and electrostatic interactions. Among the targets, Pep2 showed consistently stable interactions, while LaeA and VeA exhibited greater flexibility but remained responsive to anthocyanins. These findings highlight the potential of edible crop-derived phytochemicals, particularly anthocyanins and scopoletin, as eco-friendly antifungal agents. The structural basis provided here supports future experimental validation and the development of sustainable crop protection strategies.

Abstract

Atopic dermatitis (AD) is a chronic inflammatory skin disease with rising global prevalence and substantial health and psychosocial burden. This review aims to summarize recent advances in molecular pathogenesis and management of AD. Literature was searched in PubMed, ScienceDirect, Google Scholar, and accredited national journals, focusing on the past ten years. Inclusion criteria were full-text articles in English or Indonesian addressing epidemiology, pathogenesis, clinical features, and management. Irrelevant or incomplete studies were excluded. Selected articles were screened, classified by theme, and analyzed narratively following PRISMA guidelines. Findings show that AD prevalence continues to increase worldwide, with major impacts from chronic pruritus, recurrent flares, and psychosocial distress. Key mechanisms include genetic predisposition, especially filaggrin mutations, and immune dysregulation involving Th2, Th17, and Th22 pathways. Current treatments range from topical therapies to biologics and JAK inhibitors, emphasizing individualized care. In conclusion, AD is a lifelong multifactorial disease requiring comprehensive management. Advances in pathophysiology have expanded therapeutic options, with biologics and JAK inhibitors showing strong efficacy. Globally, priorities include precision medicine, early intervention, and wider access to novel therapies. In Indonesia, urgent needs are early detection in primary care, integration of AD management into national health programs, and ensuring affordable treatment access.

Abstract

Human Papillomavirus (HPV) is a sexually transmitted infection (STI) pathogen that plays a significant role in the development of benign and malignant diseases. This study used a literature review of national and international articles (2015–2025) obtained through Google Scholar, PubMed, and accredited journals. HPV is classified into high-risk types associated with cancer (primarily HPV 16 and 18) and low-risk types that commonly cause genital warts. Initial infection is often asymptomatic, but persistent infection can lead to cell transformation due to the activity of the oncoproteins E6 and E7. Globally, HPV prevalence remains high, with regional variations and a strong association with low vaccination coverage. Management includes pharmacological therapy, surgery, and a combination of chemotherapy and radiotherapy. While the primary prevention strategy is HPV vaccination (bivalent, quadrivalent, and nonavalent), which is currently being expanded to primary school-aged girls in Indonesia. Recent developments include new-generation therapeutic vaccines (Vvax001, PANHPVAX) that promise broader protection. It can be concluded that primary vaccination remains the most effective strategy to reduce the burden of disease caused by HPV, so that increased immunization coverage, public education, and further research related to new generation vaccines are needed.

Abstract

Sweet corn (Zea mays L. Saccharata Sturt) is one of the cereal crops that serves as an important food source in Indonesia, yet its productivity is often disrupted by pest attacks. This study aims to determine the diversity, dominance, and evenness of pests on sweet corn (Zea mays L. Saccharata Sturt). The research was conducted in Telagawaru Village, Labuapi District, West Lombok Regency, from November 2024 to January 2025. A descriptive method with a field survey technique was applied at two cultivation sites with a total area of 725 m². Each site was divided into five observation blocks measuring 5 × 5 meters, with data collection carried out using yellow pan traps and pitfall traps over five weekly observations. The results showed a total of 452 pest individuals consisting of 28 genera, 19 families, and 6 orders (Coleoptera, Diptera, Hemiptera, Hymenoptera, Lepidoptera, and Orthoptera). Site 1 had a Shannon-Wiener diversity index (H') = 2.69, Simpson dominance index (D) = 0.095, and evenness index (E) = 0.527, with the dominant genus being Bactrocera sp. (41 individuals). Site 2 recorded (H') = 2.12, (D) = 0.222, and (E) = 0.332, dominated by Bactrocera sp. (108 individuals). Both sites indicated stable and balanced ecological conditions, showing high potential for the application of sustainable biological control.

Abstract

Dragonflies are a part of biodiversity that possess aesthetic value due to their colorful appearance, as well as ecological, environmental, ecotourism, and educational significance. Segenter Waterfall in West Lombok has a unique bio-ecological characteristic, as it provides a habitat for various interesting dragonfly species. This can be utilized as an object for ecotourism and a learning resource. The aim of this research was to analyze the diversity of dragonflies in Segenter Waterfall. The method used in this research was a survey method with an area exploration technique following predetermined transect lines based on observation results: the edge path, the middle path, and the watershed path. The sweeping net method was used to collect dragonflies that could not be identified in the field for further observation in the laboratory. The results showed that the highest species abundance was Orthetrum sabina (0.55) and the lowest was Anax guttatus (0.19). Meanwhile, the highest diversity index was found in the water path (2.96) and the lowest in the middle path (2.74). In conclusion, the diversity of dragonfly species varies across each observation path, with the highest order being the Water Path, followed by the Edge Path, and the lowest being the Middle Path in the Segenter Waterfall area, Lombok Island.
