Abstract

The utilization of pineapple peel waste as a fermentation substrate has the potential to increase product value while reducing environmental pollution. One product that can be developed from this waste is nata de pina. This study aimed to analyze the effects of Acetobacter xylinum starter concentration and fermentation time on the quality of nata de pina. The research employed a quantitative experimental method using a Completely Randomized Design (CRD) with three replications. The treatments consisted of starter concentrations of 10%, 15%, and 20%, and fermentation periods of 8, 10, and 12 days. The observed parameters included nata thickness, yield, color, and texture. Data were analyzed using Two-Way ANOVA, and Tukey's post hoc test at a 5% significance level. The results showed that starter concentration and fermentation time significantly affect the thickness and yield of nata de pina with the results showing a significant effect (p < 0.05). The highest thickness (0.78 mm) and yield (48%) were obtained at a 20% starter concentration with 12 days of fermentation. The best color and texture were produced by nata de pina fermented with a 20% starter concentration for 10 days. Furthermore, The results showed no significant interaction between starter concentration and fermentation time on nata thickness (p > 0.05), whereas a significant interaction was observed for nata yield (p < 0.05). In conclusion, increasing the concentration of A. xylinum starter and extending fermentation time improved the physical quality of nata de pina, while the combination of a 20% starter concentration and 10 days of fermentation produced the best characteristics. These findings demonstrate the potential of pineapple peel waste as a sustainable raw material for producing value-added functional food.

Abstract

AbstrakWilayah kepulauan memiliki tantangan pendidikan yang kompleks akibat keterbatasan akses, sarana pendukung, serta rendahnya intensitas kolaborasi antarpemangku kepentingan pendidikan. Kondisi tersebut juga dialami sekolah mitra di Desa Gili Indah, Kabupaten Lombok Utara, yang masih menghadapi keterbatasan dalam identifikasi masalah pendidikan berbasis data dan penyusunan solusi yang sesuai dengan karakteristik wilayah kepulauan. Berdasarkan kondisi tersebut, kegiatan Pengabdian kepada Masyarakat ini bertujuan meningkatkan pemahaman dan kapasitas pemangku kepentingan pendidikan dalam mengidentifikasi, menganalisis, dan merumuskan solusi terhadap permasalahan pendidikan di wilayah kepulauan. Metode pelaksanaan menggunakan pendekatan Participatory Action Research (PAR) yang dipadukan dengan Problem-Driven Iterative Adaptation (PDIA). Kegiatan dilaksanakan melalui tahapan diseminasi, pelatihan, pendampingan, dan penyusunan Rencana Tindak Lanjut (RTL) dengan memanfaatkan data Rapor Pendidikan sebagai dasar identifikasi masalah. Kegiatan diikuti oleh 17 peserta yang terdiri atas 1 Kepala UPTD Dikbudpora Kecamatan Pemenang, 4 Pengawas Dikbudpora Kabupaten Lombok Utara, 4 kepala sekolah, dan 8 guru dari sekolah mitra. Pelaksanaan kegiatan menunjukkan adanya peningkatan pemahaman peserta terhadap tahapan identifikasi masalah berbasis PDIA sebesar 87%, tersusunnya empat dokumen RTL sekolah, serta terbentuknya komitmen kolaboratif antarpemangku kepentingan pendidikan. Kegiatan ini menunjukkan bahwa pendekatan PDIA efektif memperkuat kapasitas sekolah dalam penyelesaian masalah pendidikan berbasis data, sekaligus mendorong kolaborasi yang berkelanjutan dalam mendukung peningkatan mutu pendidikan di wilayah kepulauan. Kata kunci: kolaborasi pendidikan; pengabdian masyarakat; problem-driven iterative adaptation; rapor pendidikan; wilayah kepulauan. Abstract Island regions face complex educational challenges due to limited accessibility, inadequate supporting infrastructure, and low levels of collaboration among educational stakeholders. These conditions are also experienced by partner schools in Gili Indah Village, North Lombok Regency, Indonesia, where schools continue to encounter difficulties in conducting data-driven problem identification and developing solutions that reflect the unique characteristics of island communities. In response to these challenges, this community service program aimed to enhance the knowledge and capacity of educational stakeholders in identifying, analyzing, and addressing educational problems in island areas. The program adopted a Participatory Action Research (PAR) approach integrated with the Problem-Driven Iterative Adaptation (PDIA) framework. Activities were implemented through four stages: dissemination, training, mentoring, and the development of School Action Plans, using the Education Report Card (Rapor Pendidikan) as the primary source for problem identification. The program involved 17 participants, consisting of one Head of the Pemenang District Education Office, four school supervisors from the North Lombok Regency Education Office, four school principals, and eight teachers from partner schools. The implementation resulted in an 87% improvement in participants' understanding of PDIA-based educational problem identification, the completion of four school action plan documents, and the establishment of a collaborative commitment among educational stakeholders. These findings demonstrate that the PDIA approach effectively strengthens schools' capacity for data-driven educational problem solving while fostering sustainable collaboration to support continuous educational quality improvement in island regions. Keywords: collaborative education; community service; education report card; island regions; problem-driven iterative adaptation.

Abstract

Plant-derived aromatic compounds encompass chemically distinct groups and should not be conflated with every molecule that is chemically aromatic. In this review, the term is operationally restricted to plant-derived secondary metabolites and volatile or semi-volatile constituents investigated in relation to local, native, indigenous, endemic, medicinal, or aromatic plant resources; industrial aromatic amines and environmental polycyclic aromatic hydrocarbons are outside the intended scope. This study maps the research landscape using a hybrid systematic literature review (SLR) and bibliometric approach. The original Scopus search, conducted on April 28, 2026, yielded 149 English-language, open-access journal articles after document-type, language, and full-text-access screening. Publication performance and science-mapping outputs were examined using VOSviewer. The current corpus shows a marked increase in publication output in recent years and a concentration of records in China, the United States, Spain, India, Italy, and several other countries. Keyword co-occurrence is dominated by chemistry, chemical composition, plant extract, antioxidant, and related analytical terms. The review therefore supports a research landscape centered on phytochemical characterization and application, while molecular, biosynthetic, and sustainability-oriented topics are also present. Because the study relies on a single database, an exact-phrase search, and an open-access subset, the findings are interpreted as patterns within the included corpus rather than as an exhaustive representation of the field. Future work should strengthen corpus validation, metadata standardization, regionally diverse plant research, mechanistic studies, and sustainable applications.
