Abstract

The water used by the community in Kota Bangun II Village for drinking and daily needs comes from three types of groundwater sources, namely natural sources, drilled wells and dug wells. This research aims to determine the suitability of the air consumed by the people of Kota Bangun II Village. This type of research is descriptive quantitative with the parameters tested being physical, chemical and biological parameters. The air sampling technique used in this research was purposive sampling. The air testing site at the Air Quality Laboratory and Microbiology and Aquaculture Biotechnology Laboratory, Faculty of Fisheries and Marine Sciences, Mulawarman University, research was carried out for 3 months, namely January-March 2023. Based on the research results which have been compared with PERMENKES No. 492 of 2010 and Indonesian Government Regulation no. 82 of 2001 and Government Regulation no. 20 of 1990 that the source of drinking water in Kota Bangun II Village cannot be consumed directly and does not qualify as standard water

Abstract

The Dutch jasmine plant (Combretum indicum) from the Combretaceae family is an aromatic ornamental plant known for its pleasant fragrance and vibrant flowers. This study aimed to formulate and evaluate aromatherapy preparations derived from Dutch jasmine essential oil and to determine the optimal formulation that meets physical quality standards for aromatherapy products. The research employed a true experimental design with quantitative and qualitative descriptive analyses. Four formulations were developed using different concentrations of essential oil: 2% (F1), 3% (F2), 4% (F3), and 5% (F4). The formulations were evaluated through hedonic testing by 35 panelists using a standardized assessment sheet. Data were analyzed using descriptive statistics with Microsoft Excel. The results showed that among the four formulations, the 4% essential oil formulation (F3) received the highest preference score from panelists and met the physical quality criteria for aromatherapy products. Therefore, the F3 formulation was identified as the most effective and desirable aromatherapy preparation derived from Dutch jasmine essential oil.

Abstract

Microplastics are plastic particles smaller than 5 mm that originate from anthropogenic activities or environmental degradation. The estuarine waters of the Kenyamukan River in Sangatta, East Kutai Regency, are highly vulnerable to microplastic contamination due to intensive local activities such as fishing port operations, residential settlements, docks, and tourism sites. This study aimed to analyze the types and forms of microplastics found in several fish species inhabiting the estuarine area. The research employed a descriptive–analytical approach, with sampling conducted from March to May 2025. Fish organs analyzed included the gills and digestive system, which were extracted using NaCl solution, 10% KOH, and 30% Hâ‚‚Oâ‚‚, followed by observation under a stereo microscope. The results revealed the presence of microplastics in goatfish (Parupeneus indicus), spotted scat (Scatophagus sp.), rabbitfish (Siganus guttatus), and golden snapper (Lutjanus johnii). The identified microplastic types consisted of fibers (52%), fragments (27%), films (12%), and pellets (9%), with a total of 173 particles. The microplastic sizes ranged from 0.0012 mm to 0.1399 mm and exhibited various colors, including black, red, yellow, blue, green, transparent, orange, and pink. These findings indicate a high level of microplastic contamination in the Kenyamukan River estuary, posing potential threats to the aquatic ecosystem and the trophic food chain.

Abstract

Penelitian ini berlatar belakang pada perubahan arus teknologi yang begitu cepat sehingga mengharuskan pendidik untuk menyesuaikan sarana dan prasarana yang ada, agar materi pembelajaran dapat tersampaikan dengan baik. Penelitian ini ditujukan untuk melihat bagaimana pengaruh penggunaan media pembelajaran berbasis website Biology Simulations terhadap minat dan hasil belajar siswa pada materi sel kelas VII SMP. Jenis penelitian yang digunakan ialah kuantitatif yang memakai metode quasi eksperimen serta rancangan post-test only control group design. Sampel diambil dengan teknik cluster random sampling. Analisis data dilakukan dengan uji Independent Sample T-Test dengan signifikansi sebesar 5% dan didapatkan nilai signiifikansi dari minat belajar adalah 0,004 0,05 serta hasil belajar adalah 0,019 0,05. Bersumber pada data evaluasi post-test, diambil kesimpulan bahwa media pembelajaran berbasis website Biology Simulations memberikan pengaruh yang dapat dibuktikan dengan meningkatnya minat dan hasil belajar pada materi sel kelas VII SMP.

Abstract

Penelitian ini bertujuan mengembangkan produk e-booklet berbasis potensi lokal ekosistem mangrove di pantai pendopo Balikpapan sebagai media pembelajaran biologi. Model pengembangan yang digunakan dalah model ADDIE yang teridi dari tahap: Analyze (analisis), Design (desain), Development (pengembangan), Implementation (implementasi), dan Evaluation (evaluasi). Penelitian ini hanya dilakukan sampai tahap pengembangan. Data penelitian diperoleh menggunakan angket validasi, angket respon guru dan siswa. E-booklet yang dikembangkan divalidasi oleh ahli media dan ahli materi. Uji coba dilakukan kepada 2 guru biologi dan 33 siswa kelas X-G di SMA Negeri 7 Balikpapan. Berdasarkan hasil penelitian dan pengembangan dapat disimpulkan bahwa media pembelajaran e-booklet berbasis potensi lokal ekosistem mangrove memenuhi aspek kevalidan dengan kategori (sangat valid) pada aspek media sebesar 87% dan aspek materi sebesar 85%. Media pembelajaran e-booklet berbasis potensi lokal ekosistem mangrove memenuhi aspek kepraktisan dengan respon siswa dan guru. Pada uji coba lapangan diperoleh respon guru 80% dan respon siswa 83% dengan kategori (Positif) dan e-booklet layak untuk digunakan dalam proses pembelajaran.
