Abstract

Daun dalundung merupakan salah satu tanaman lokal yang banyak dikonsumsi masyarakat Luwuk sebagai sayuran dan dipercaya memiliki khasiat obat tradisional. Analisis fitokimia menunjukkan bahwa daun ini mengandung berbagai metabolit sekunder seperti flavonoid, tanin, saponin, alkaloid, dan minyak atsiri yang berpotensi sebagai antibakteri alami yang mampu menghambat pertumbuhan mikroorganisme. Berdasarkan hal tersebut, penelitian ini bertujuan untuk mengetahui aktivitas antibakteri infusa daun dalundung terhadap pertumbuhan Escherichia coli secara in vitro, baik melalui metode difusi (sumuran) maupun metode dilusi (pengenceran bertingkat). Penelitian ini menggunakan rancangan eksperimental laboratorium dengan empat variasi konsentrasi infusa daun dalundung (22%, 16,5%, 11%, dan 5,5%) serta dua kontrol, yaitu kontrol positif (amoksisilin) dan kontrol negatif (akuades steril). Uji daya hambat dilakukan dengan metode difusi sumuran untuk mengukur zona hambat pertumbuhan bakteri, sedangkan metode dilusi digunakan untuk menentukan Konsentrasi Hambat Minimum dan Konsentrasi Bunuh Minimum. Data hasil pengamatan dianalisis secara deskriptif kuantitatif dengan menilai diameter zona hambat dan keberadaan pertumbuhan koloni pada setiap perlakuan. Hasil penelitian menunjukkan bahwa infusa daun dalundung memiliki aktivitas antibakteri terhadap E. coli pada seluruh konsentrasi uji, dengan zona hambat tertinggi pada konsentrasi 16,5% sebesar 7,8 mm yang tergolong kategori sedang. Namun, uji dilusi menunjukkan bahwa tidak ada konsentrasi yang mencapai nilai KBM, sehingga efek antibakteri infusa daun dalundung bersifat bakteriostatik. Hasil ini menegaskan bahwa pelarut air hanya mengekstraksi senyawa polar seperti flavonoid dan tanin yang berperan dalam aktivitas penghambatan. Disarankan penelitian lanjutan menggunakan pelarut organik (etanol atau metanol), uji fitokimia kuantitatif, dan metode mikrodilusi spektrofotometri untuk memperoleh hasil yang lebih akurat dan potensi antibakteri yang optimal. Dalundung leaves are a local plant widely consumed by the Luwuk people as a vegetable and are believed to have traditional medicinal properties. Phytochemical analysis shows that these leaves contain various secondary metabolites such as flavonoids, tannins, saponins, alkaloids, and essential oils that have the potential to act as natural antibacterials that can inhibit the growth of microorganisms. Based on this, this study aims to determine the antibacterial activity of dalundung leaf infusion on the growth of Escherichia coli in vitro, both through the diffusion method (well) and the dilution method (multiple dilutions). This study used a laboratory experimental design with four variations in the concentration of dalundung leaf infusion (22%, 16.5%, 11%, and 5.5%) and two controls, namely a positive control (amoxicillin) and a negative control (sterile aquadest). The inhibitory test was carried out using the well diffusion method to measure the inhibition zone of bacterial growth, while the dilution method was used to determine the Minimum Inhibitory Concentration and Minimum Bactericidal Concentration. The observation data were analyzed descriptively quantitatively by assessing the diameter of the inhibition zone and the presence of colony growth in each treatment. The results showed that dalundung leaf infusion had antibacterial activity against E. coli at all test concentrations, with the highest inhibition zone at a concentration of 16.5% of 7.8 mm, which is classified as moderate. However, the dilution test showed that no concentration reached the MBC value, so the antibacterial effect of dalundung leaf infusion was bacteriostatic. These results confirm that the water solvent only extracts polar compounds such as flavonoids and tannins that play a role in inhibitory activity. Further research is recommended using organic solvents (Ethanol or Methanol), quantitative phytochemical tests, and spectrophotometric microdilution methods to obtain more accurate results and optimal antibacterial potential.

Abstract

Nyamuk Culex sp. merupakan salah satu vektor penyakit menular seperti filariasis yang masih menjadi masalah kesehatan masyarakat di Indonesia. Larva Culex sp. hidup di perairan yang mengandung bahan organik dan aktif memakan mikroorganisme serta kotoran organik. Upaya pengendalian larva umumnya menggunakan larvasida kimia, namun penggunaannya dalam jangka panjang dapat menimbulkan resistensi dan dampak negatif terhadap lingkungan. Oleh karena itu, diperlukan alternatif larvasida alami yang lebih aman dan ramah lingkungan, salah satunya berasal dari tanaman jarak kepyar. Penelitian ini bertujuan untuk mengetahui efektivitas ekstrak daun jarak kepyar terhadap mortalitas larva Culex sp. Penelitian menggunakan metode eksperimen sejati dengan rancangan Posttest Only Control Group Design. Sampel berupa larva Culex sp. instar III dan IV sebanyak 25 ekor per kelompok perlakuan. Ekstrak daun jarak kepyar dibuat dengan metode maserasi dingin dan diuji pada dua konsentrasi, yaitu 138 ppm dan 453 ppm, serta disertai kontrol positif dan negatif. Data mortalitas dianalisis menggunakan uji ANOVA dan Mann–Whitney U. Hasil penelitian menunjukkan bahwa mortalitas larva meningkat seiring peningkatan konsentrasi, yaitu pada instar III sebesar 5,33% (138 ppm) dan 10,67% (453 ppm), sedangkan pada instar IV sebesar 4% (138 ppm) dan 8% (453 ppm). Analisis statistik menunjukkan nilai signifikansi > 0,05, yang berarti tidak terdapat perbedaan nyata antar konsentrasi maupun antar instar. Kesimpulannya, ekstrak daun jarak kepyar belum efektif sebagai larvasida terhadap larva Culex sp. karena tingkat kematian masih di bawah nilai LC₅₀ dan LC₉₀. Disarankan penelitian lanjutan dengan konsentrasi ekstrak lebih tinggi, waktu paparan lebih lama, serta uji fitokimia untuk mengidentifikasi senyawa aktif yang berpotensi sebagai larvasida nabati. Culex sp. mosquitoes are one of the vectors of infectious diseases such as filariasis, which remains a public health problem in Indonesia. Culex sp. larvae live in waters containing organic matter and actively feed on microorganisms and organic waste. Larvae control efforts generally use chemical larvicides, but long-term use can cause resistance and negative impacts on the environment. Therefore, safer and more environmentally friendly natural larvicides are needed, one of which is derived from the castor bean plant. This study aims to determine the effectiveness of castor bean leaf extract on the mortality of Culex sp. larvae. The study used a true experimental method with a Posttest Only Control Group Design. Samples were 25 instar III and IV Culex sp. larvae per treatment group. The castor bean leaf extract was prepared using the cold maceration method and tested at two concentrations, namely 138 ppm and 453 ppm, and accompanied by positive and negative controls. Mortality data were analyzed using ANOVA and Mann–Whitney U tests. The results showed that larval mortality increased with increasing concentration, namely in instar III by 5.33% (138 ppm) and 10.67% (453 ppm), while in instar IV by 4% (138 ppm) and 8% (453 ppm). Statistical analysis showed a significance value > 0.05, which means there was no significant difference between concentrations or between instars. In conclusion, castor bean leaf extract is not yet effective as a larvicide against Culex sp. larvae because the mortality rate is still below the LC₅₀ and LC₉₀ values. Further research is recommended with higher extract concentrations, longer exposure times, and phytochemical tests to identify active compounds that have the potential as botanical larvicides.

Abstract

Gangguan pendengaran akibat kebisingan merupakan salah satu dampak lingkungan kerja yang tidak aman dan menjadi isu penting dalam keselamatan dan kesehatan kerja (K3). Data WHO (2023) menunjukkan sekitar 430 juta orang mengalami gangguan pendengaran dan diperkirakan meningkat hingga 700 juta pada tahun 2050. Industri pembangkit listrik termasuk sektor dengan tingkat kebisingan tinggi yang berisiko menimbulkan gangguan pendengaran pada pekerja. Penelitian ini bertujuan untuk mengetahui gambaran gangguan pendengaran pada karyawan PT Unit Layanan Pembangkit Listrik Tenaga Diesel (ULPLTD) Luwuk. Penelitian menggunakan desain observasional deskriptif dengan teknik total sampling terhadap 66 pekerja aktif. Pemeriksaan pendengaran dilakukan menggunakan hearing test berbasis frekuensi suara (Pitch/Hz) dan audiometri tutur, kemudian dianalisis secara univariat. Hasil menunjukkan bahwa pada telinga kanan, sebagian besar pekerja memiliki pendengaran normal (78,6%), sedangkan 16,1% mengalami gangguan pendengaran ringan dan 5,4% sedang. Pada telinga kiri, 87,5% pekerja memiliki pendengaran normal, 10,7% mengalami gangguan ringan, dan 1,8% sedang. Secara keseluruhan, terdapat 19,7% pekerja yang mengalami gangguan pendengaran ringan hingga sedang pada salah satu atau kedua telinga. Pemeriksaan audiometri tutur menunjukkan seluruh pekerja masih mampu mengenali dan memahami suara dengan baik. Gangguan pendengaran diduga berkaitan dengan paparan kebisingan yang melebihi Nilai Ambang Batas 85 dBA. Oleh karena itu, perusahaan disarankan melakukan deteksi dini secara berkala, pengendalian kebisingan, serta meningkatkan kepatuhan penggunaan alat pelindung diri. Noise-induced hearing loss is one of the impacts of unsafe working environments and remains an important issue in occupational health and safety. According to the World Health Organization (2023), approximately 430 million people worldwide experience hearing impairment, and this number is projected to increase to 700 million by 2050. Power generation industries are among the sectors with high noise exposure, placing workers at risk of hearing disorders. This study aimed to describe the occurrence of hearing disorders among employees at the Diesel Power Plant Service Unit (ULPLTD) Luwuk. A descriptive observational study was conducted using a total sampling technique involving 66 active workers. Hearing assessments were performed using frequency-based hearing tests (Pitch/Hz) and speech audiometry. Data were analyzed using univariate analysis. The results showed that in the right ear, 78.6% of workers had normal hearing, while 16.1% experienced mild hearing loss and 5.4% had moderate hearing loss. In the left ear, 87.5% of workers had normal hearing, 10.7% had mild hearing loss, and 1.8% had moderate hearing loss. Overall, 19.7% of workers experienced mild to moderate hearing loss in one or both ears. Speech audiometry indicated that all workers (100%) were still able to recognize and understand speech sounds. Hearing disorders were suspected to be associated with noise exposure exceeding the permissible exposure limit of 85 dBA. Therefore, regular early detection, effective noise control measures, and strict use of personal protective equipment are strongly recommended.

Abstract

Background: Dengue fever remains a major public health problem in tropical regions, including Indonesia, where vector control relies heavily on synthetic larvicides that pose environmental and health concerns. Plant-based larvicides have emerged as promising alternatives; however, comparative evidence regarding the influence of solvent polarity and leaf developmental stage on larvicidal efficacy remains limited. Objectives: This study evaluated the larvicidal activity of young and old castor bean leaf extracts obtained using different solvents against Aedes sp. larvae. Method: A laboratory-based experimental study was conducted following WHO guidelines for mosquito larvicide testing. Young and old leaves of castor were extracted separately using n-hexane, ethyl acetate, ethanol, and distilled water through multistage maceration. Third-instar Aedes sp. larvae were exposed to graded concentrations (75–200 ppm) of each extract, with 25 larvae per treatment and three replications. Larval mortality was recorded hourly for 24 hours. Probit analysis was used to determine LC₅₀ and LC₉₀ values with 95% confidence intervals, and differences among treatments were analyzed using one-way ANOVA (p < 0.05). Results: All extracts exhibited larvicidal activity against Aedes sp., with efficacy varying according to solvent type and leaf age. Ethanol extracts of old leaves produced the highest larval mortality, while ethyl acetate extracts of young leaves showed the lowest LC₅₀ values. Phytochemical screening confirmed the presence of alkaloids, flavonoids, saponins, tannins, and steroids in most extracts. LC₅₀ values ranged from 131.403 to 410.225 ppm, whereas LC₉₀ estimates were substantially higher and exceeded the tested concentration range, indicating extrapolation beyond observed data.  Conclusion: The larvicidal effectiveness of castor leaf extracts against Aedes sp. is influenced by both solvent polarity and leaf developmental stage. Old leaves extracted with ethanol and young leaves extracted with ethyl acetate demonstrated comparatively higher larvicidal potential. These findings support the potential of castor as a botanical larvicide, although further studies incorporating standard larvicide controls, quantitative phytochemical analysis, and field validation are required before operational application.   Keywords: Aedes sp; ricinus communis linn; castor

Abstract

Banggai yam (Dioscorea sp.) is an indigenous carbohydrate source in Central Sulawesi with potential value for functional-food development. However, comparative glycemic index (GI) data for local Banggai yam varieties remain limited. This study aimed to determine the GI of seven Banggai yam varieties using the incremental area under the curve (iAUC) approach based on ISO 26642:2010 principles. The study used a parallel-group design with paired reference-food testing. Seventy healthy adults were allocated to seven groups (n=10 per variety). Each participant completed two test sessions after an overnight fast: a glucose reference food equivalent to 50 g anhydrous glucose and one assigned steamed yam portion containing 50 g available carbohydrate. Capillary blood glucose was measured at 0, 15, 30, 60, and 120 minutes. The calculated GI values showed clear variation across varieties. Bunggon (61.5), Ateno (63.91), Boan (67.7), and Tuu (67.8) were classified as moderate-GI varieties, whereas Pusus (87.3), Sombok (94.4), and Pasandil (95.44) were classified as high-GI varieties. The consolidated glucose-response curves also indicated more attenuated postprandial responses for Ateno and Tuu than for the high-GI varieties. These findings indicate that Banggai yam exhibits substantial inter-varietal diversity in glycemic response. Moderate-GI varieties, particularly Bunggon and Ateno, are promising raw materials for Banggai yam–based food products intended to provide a lower glycemic impact than the high-GI varieties
