Hymenoptera is one of the insect orders that plays an important role in ecosystems, serving as pollinators, predators, and decomposers. This study was conducted in the Kerandangan Nature Tourism Park, located in Senggigi Village, Batu Layar Subdistrict, West Lombok Regency, West Nusa Tenggara Province. The aim of this study was to determine the diversity and distribution patterns of Hymenoptera. The research was carried out from November–December 2024 using a descriptive-exploratory method. Data were collected using two sampling techniques: pitfall traps and sweep nets, applied at three stations: Intensive Utilization Block, Protection Block, and Rehabilitation Block. The results showed the presence of 15 species from the order Hymenoptera, classified into two families: Apidae and Formicidae, with a total of 503 individuals. The overall diversity index (H') was 2,02. When ranked by diversity index values at each block, the highest diversity was found in the Protection Block (H' = 2,18), followed by the Intensive Utilization Block (H' = 1,74), and the lowest in the Rehabilitation Block (H' = 1,36). Overall, the distribution pattern of Hymenoptera individuals in TWA Kerandangan was generally random, with Morisita index values ranging from 0,00 to 0,43 (Id < 1).

Tujuan dari penelitian ini adalah mengidentifikasi jenis-jenis lalat buah (Bactrocera spp.) yang menyerang buah-buahan di pasar tradisional Kota Mataram serta menilai tingkat kelimpahannya pada berbagai jenis inang. Penelitian dilakukan di empat pasar utama, yaitu Dasan Agung, Bertais, Kebon Roek, dan Pagesangan. Sampel buah yang menunjukkan gejala serangan lalat buah dikumpulkan menggunakan teknik purposive random sampling, kemudian disimpan pada media pasir hingga mencapai fase imago. Identifikasi spesies dilakukan menggunakan kunci determinasi Bactrocera. Hasil penelitian menunjukkan keberadaan empat spesies utama: Bactrocera albistrigata de Mejeire yang menyerang jambu air; Bactrocera carambolae Drew and Hancock yang menyerang belimbing; Bactrocera caudatus Fab yang menyerang jambu biji; dan Bactrocera dorsalis yang menyerang cabai. Temuan penelitian ini tidak hanya bermanfaat untuk pengendalian hama pertanian, tetapi juga memiliki implikasi dalam bidang pendidikan. Lalat buah dapat dimanfaatkan sebagai media pembelajaran biologi di SMA untuk materi keanekaragaman hayati, daur hidup serangga, hubungan ekologi, serta keterkaitan antara biologi dan permasalahan pertanian lokal. The aim of this study is to identify the kinds of fruit flies (Bactrocera spp.) that prey on fruits in Mataram City's traditional markets and to assess the degree of abundance in different host species. Dasan Agung, Bertais, Kebon Roek, and Pagesangan were the four primary markets where the study was carried out. Purposive random sampling was used to gather fruit samples exhibiting fruit fly attack symptoms, which were then kept in sand media until the imago phase. The Bactrocera determination key was used to identify the species. The results showed the existence of four primary species: Bactrocera albistrigata de Mejeire, which attacks water apples; Bactrocera carambolae Drew and Hancock, which strikes starfruit; Bactrocera Caudatus Fab, which attacks guava; and Bactrocera Dorsalis, which targets chile. The findings of this study have implications for education in addition to helping to manage agricultural pests. High school biology classes can employ fruit flies as a teaching tool for subjects including biodiversity, insect life cycles, ecological relationships, and the connection between biology and regional agricultural problems.

Student engagement in laboratory quality systems is essential for strengthening maintenance compliance and technical competence, particularly when aligned with international standards such as ISO 17025:2017. This study aims to (1) design a student engagement model that complies with the requirements of clauses 6.2.2 and 7.6 of ISO 17025:2017 and (2) analyze the impact of its implementation on improving equipment maintenance compliance and student technical competence. The research design employs an explanatory sequential mixed-methods approach, with a dominant quantitative component and qualitative support. The research subjects included 22 key informants (laboratory coordinators, laboratory heads, technicians, and students) who were selected with purposive sampling. Data were collected through structured questionnaires, in-depth interviews, FGDs, and participant observation. Quantitative data were analyzed using multiple linear regression using SPSS 25, while qualitative data were analyzed thematically. The results showed that the model designed based on four pillars: training, documented participation SOPs, internal audit simulations, and portfolio systems effectively transformed students from passive learners into competent contributors to the laboratory quality assurance system. The implementation of the model was proven to significantly improve maintenance compliance (mean = +1.81) and technical competence (mean = +1.59). Regression analysis confirmed that the model explained 80.2% of the variance in compliance (R² = 0.802) and 78.1% of the variance in competence (R² = 0.781), with documentation quality (β = 0.462; β = 0.423) as the strongest predictor. Qualitative findings revealed a shift in mindset from obligation to ownership as a key mechanism. This study concludes that the developed model not only aligns with ISO 17025 but also provides a strategic approach to building sustainable quality cultures in educational laboratories.

Lumut (Bryophyta) merupakan salah satu komponen keanekaragaman hayati yang berperan penting dalam ekosistem, baik sebagai indikator kualitas lingkungan maupun dalam siklus hara dan retensi air. Namun, informasi mengenai keanekaragaman dan pola distribusi lumut di kawasan konservasi, khususnya di Taman Wisata Alam (TWA) Suranadi, Lombok Barat, masih sangat terbatas. Padahal, kawasan ini menghadapi berbagai tekanan ekologis akibat aktivitas wisata dan perubahan penggunaan lahan yang berpotensi mengganggu habitat lumut yang sensitif terhadap perubahan mikrohabitat. Kurangnya data dasar tentang komunitas lumut menjadi kendala dalam upaya konservasi dan pengelolaan kawasan secara berkelanjutan. Penelitian ini bertujuan untuk menganalisis keanekaragaman jenis dan pola distribusi tumbuhan lumut (Bryophyta) di Kawasan Taman Wisata Alam Suranadi, Lombok Barat. Penelitian dilaksanakan pada bulan Juli hingga Desember 2025 di zona pemanfaatan dan zona perlindungan. Metode yang digunakan adalah deskriptif eksploratif dengan teknik pengumpulan data berupa transek dan kuadrat secara purposive sampling. Hasil penelitian menemukan 22 spesies tumbuhan lumut yang tergolong dalam dua kelas, yaitu Bryopsida (lumut daun) dan Hepaticopsida (lumut hati). Indeks keanekaragaman Shannon-Wiener (H') menunjukkan nilai 1,034 yang termasuk dalam kategori sedang. Pola distribusi sebagian besar spesies bersifat mengelompok. Pola distribusi mengelompok ini dipengaruhi oleh faktor lingkungan seperti kelembaban tinggi, naungan kanopi, dan ketersediaan substrat. Kawasan Taman Wisata Alam Suranadi perlu dijaga kelestariannya untuk mendukung konservasi keanekaragaman hayati lumut.

Dragonflies (Odonata) are bioindicators of environmental quality that are sensitive to changes in habitat conditions. This research aimed to analyze the dragonfly species found in the Kerandangan Nature Tourism Park, analyze their distribution patterns, and determine their diversity level. The research was conducted in three observation blocks, namely utilization, rehabilitation, and protection blocks. Sampling in this study was conducted using the line transect method with direct field observation. Distribution patterns were analyzed using the dispersion index, while diversity was measured using the Shannon–Wiener index (H’). The results showed that 18 dragonfly species belonging to 8 families were identified. The distribution patterns of dragonflies, both overall and within each block, tended to be clumped. The dragonfly diversity index (H’) in the Kerandangan Nature Tourism Park was 2.12, indicating that the ecosystem is relatively stable. In addition, damselflies (Zygoptera) were only found in the utilization block, which has water sources, and were absent in the rehabilitation and protection blocks. This finding suggests that abiotic and biotic environmental factors influence the presence and distribution of dragonflies in the study area. This research is expected to contribute scientific information to support enviromental management and conservation efforts in the Kerandangan Nature Tourism Park.

Butterflies of the suborder Rhopalocera play an important ecological role as pollinators and bioindicators of environmental quality. The Sendang Gile Waterfall area, North Lombok, contains diverse habitats that potentially support a high diversity of butterfly species, yet information on their community structure remains limited. This study aimed to identify the species composition and analyze the community structure of Rhopalocera butterflies in the area. The research was conducted from April to May 2026 at four observation sites using a survey method. Butterflies were collected using sweep nets and identified based on morphological characteristics. Community structure was analyzed using the Shannon–Wiener diversity index (H′), Pielou evenness index (E), and Simpson dominance index (D). A total of 1,207 individuals representing 31 species from six families were recorded. Pieridae was the most abundant family, followed by Nymphalidae and Papilionidae, whereas Riodinidae, Lycaenidae, and Hesperiidae were represented by relatively few individuals. The waterfall site showed the highest diversity (H′ = 2.73) and evenness (E = 0.91), while Gate 1 had the lowest diversity (H′ = 2.10) and evenness (E = 0.67). Dominance values at all observation sites were low (D < 0.5). These results indicate that the Rhopalocera butterfly community in the Sendang Gile Waterfall area is relatively stable, with moderate to high species diversity, high evenness, and low dominance.

This study aimed to inventory the dragonfly species inhabiting the Sendang Gile Waterfall area, evaluate their diversity, and develop the findings into a local biodiversity-based biology learning resource for senior high school students. A descriptive exploratory approach was employed using a sweep net sampling method along three observation transects. Species diversity was analyzed using the Shannon–Wiener diversity index (H′), evenness index (E), and dominance index (C). The research findings were subsequently developed into a biology booklet and evaluated through expert validation involving material and media specialists. A total of 364 dragonfly individuals representing 12 species from five families were recorded. Euphaea lara lombokensis was the most abundant species, accounting for 119 individuals. The overall Shannon–Wiener diversity index (H′ = 1.81) indicated a moderate level of species diversity, accompanied by a relatively balanced species distribution and low dominance. The developed booklet obtained an average validation score of 90.09%, indicating that it was highly valid and suitable for educational use. These findings demonstrate that the Sendang Gile Waterfall area supports a moderately diverse dragonfly community and that the developed booklet can serve as an effective local biodiversity-based learning resource for biology education in senior high schools.
