Abstract

Sungai Bone salah satu sungai di Gorontalo yang menjadi sumber air untuk mencuci, mandi, minum dan sebagai mata pencarian bagi nelayan untuk menangkap ikan yang sering dikonsumsi oleh masyarakat setempat. Namun, masyarakat sering membuang sampah di sungai tersebut, mengakibatkan sampah akan terakumulasi ke dalam badan ikan dan akan berbahaya jika di konsumsi. Kebaruan dalam penelitian yaitu penggunaan metode spektroskopi untuk meneliti kandungan logam berat pada air dan ikan nike. Tujuan penelitian untuk menganalisis kandungan logam berat Timbal (Pb), Besi (Fe), dan Kadmium (Cd) pada air dan ikan nike di perairan Sungai Bone, Kota Gorontalo menggunakan metode Spektroskopi. Pada air menggunakan metode Spektroskopi Uv-Vis dan pada Ikan Nike menggunakan metode SSA. Hasil penelitian kandungan logam sampel air yaitu kadar logam Pb titik 1 dan 2 yakni 0,7025 dan 0,7051 ppm, logam Fe titik 1 dan 2 yaitu 0,2789 dan 0,3161 ppm dan logam Cd titik 1 dan titik 2 yaitu 0,2306 dan 0,2543 ppm, sampel ikan nike kadar logam Pb pada hari 1 dan 2 yakni 0,00681 dan 0,00564 ppm, logam Fe pada hari 1 dan 2 yaitu 0,01442 dan 0,03196 ppm dan kadar logam Cd pada hari 1 dan 2 yaitu 0,00826 dan 0,00994 ppm. Kesimpulannya kadar logam Cd dan Pb pada air sudah melebihi ambang batas, kadar logam Fe masih di bawah ambang batas ,dan sampel ikan nike kadar logam Pb, Fe dan Cd masih di bawah kadar ambang batas sesuai SNI yang sudah ditentukan sehingga masih layak untuk dikonsumsi.

Abstract

Understanding chemical equilibrium concepts poses significant challenges for high school students due to the topic’s abstract and complex nature. This literature review identifies key factors contributing to these difficulties, including widespread misconceptions, cognitive and pedagogical barriers, and environmental influences such as family support and learning resources. The review highlights the importance of constructivist and cognitive learning theories in designing effective instructional strategies that actively engage students and facilitate deeper conceptual understanding. Furthermore, the integration of educational technologies—such as interactive simulations and virtual laboratories—provides enriched learning experiences that help overcome conceptual misunderstandings. An integrated approach combining innovative teaching methods and technology use is recommended to enhance students’ comprehension of chemical equilibrium. Future research should focus on practical applications of these models and evaluate their effectiveness across diverse educational settings.

Abstract

This study aims to determine the effect of coconut pulp and seawater compost on the growth of lettuce (Lactuca Sativa L). This type of research uses a quantitative method. Based on the results of the study, the treatment of coconut pulp and seawater compost on the most optimal plant height is the treatment on the 28th day because there is the greatest potential difference in treatment compared to other days and the treatment of coconut pulp and seawater compost on the optimal number of leaves is the treatment on the 42nd day, especially in treatment 5 which produces the highest number of leaves.

Abstract

This study aims to determine how nano chitosan is produced through the ionic gelation method. The process of making nano chitosan is carried out using variations in chitosan concentrations of 1%, 5%, and 10%, and using a magnetic stirrer. Morphological tests were carried out using Scanning Electron Microscopy (SEM) to observe the shape and size of the particles formed. The addition of TPP (Trisodium Tripolyphosphate) as a crosslinker and certain surfactants are used to increase particle stability. Treatment for ±2 hours showed optimal results in terms of a more homogeneous particle size distribution. Based on the results of SEM observations, it is known that increasing the concentration and time settings and the use of appropriate surfactants can reduce wrinkles in nano chitosan particles. The particle size obtained is in the range of 278–350 nm. Thus, the ionic gelation method has proven effective in producing uniform nano chitosan and has good morphology for further applications.

Abstract

Kegiatan pengabdian kepada masyarakat ini bertujuan untuk meningkatkan pemahaman konsep hidrolisis garam melalui penerapan pendekatan multi representasi di SMAN 1 Dungaliyo. Permasalahan utama yang dihadapi siswa adalah kesulitan menghubungkan konsep makroskopik, mikroskopik, dan simbolik dalam pembelajaran kimia, yang mengakibatkan rendahnya pemahaman konseptual dan tingginya tingkat miskonsepsi. Kegiatan ini dilaksanakan melalui empat tahap, yaitu persiapan, pelaksanaan, evaluasi, dan tindak lanjut. Strategi pembelajaran mencakup pelatihan guru, pengembangan media visual dan LKPD, serta implementasi pembelajaran berbasis eksperimen, simulasi, dan notasi simbolik. Hasil kegiatan menunjukkan peningkatan signifikan dalam keterkaitan representasi kimia, kemampuan menentukan sifat larutan, menyusun reaksi dan menghitung pH, serta koreksi terhadap miskonsepsi. Lebih dari 80% siswa menunjukkan partisipasi aktif dan minat belajar yang meningkat. Pendekatan multi representasi terbukti efektif dalam menciptakan pembelajaran kimia yang bermakna, kontekstual, dan menyenangkan.

Abstract

This community service program aims to address the issue of unproductive land in three villages—Talumopatu, Sidomukti, and Motoduto—in Gorontalo Province by implementing sustainable land management practices. The program focused on soil conservation, organic farming, and polyculture techniques to rehabilitate degraded land, reduce erosion, and improve soil fertility. The initiative included training and workshops for local farmers to promote the adoption of environmentally friendly agricultural practices. Throughout the program, community participation was high, and significant progress was made in transforming underutilized land into productive green spaces. The project also emphasized the importance of crop diversity in preventing soil degradation. The results indicate that the program successfully improved land productivity, enhanced environmental awareness, and empowered local farmers with sustainable farming skills. The success of this program opens opportunities for similar initiatives in other regions facing environmental challenges.

Abstract

This research focuses on the development of contextual-based interactive learning media to improve mastery of reaction rate concepts and develop the character of high school students in remote areas. This learning media was developed to provide learning experiences that are relevant to everyday life, therefore the concepts of reaction rate are simpler to understand and apply in students. In addition, this contextual approach also aims to encourage character development, such as responsibility, discipline, creativity, curiosity, and communicativeness during the learning process. A literature review was conducted to gather articles relevant to this topic, with a published time frame of 2018 - 2025. The review shows that this media significantly helps students in understanding the concept of learning material, critical thinking, as well as strengthening positive character aspects that support learning success. This research concludes that contextual-based interactive learning can be an efficient option in the science learning process in high school.

Abstract

Sedimen merupakan bahan organik dan anorganik yang dapat mempengaruhi kualitas air. Sedimen biasanya mengandung Fosfor dan Nitrogen. Fosfor dan Nitrogen merupakan unsur hara makro yang diperlukan dalam proses pertumbuhan tanaman. Penelitian ini bertujuan untuk mengetahui kandungan fosfor (P) dan nitrogen (N) pada sedimen danau limboto maupun pupuk organik yang dibuat serta pengaruh pupuk organik terhadap tanaman kangkung darat. Analisis kandungan fosfor (P) menggunakan metode Spektrofotometer Uv-Vis. Sementara untuk kandungan nitrogen (N) menggunakan metode kjedhal. Untuk pengaplikasiannya dilakukan pada tanaman kangkung darat. Hasil yang diperoleh menunjukkan bahwa pada 3 sampel sedimen danau limboto untuk kandungan fosfor (P) dan Nitrogen (N) tergolong sangat tinggi. Kandungan fosfor (P) masing-masing sebesar titik 1= 0,48%, titik 2 = 0,45%, titik 3 = 0,44% dan kandungan nitrogen (N) sebesar titik 1= 12,35%, titik 2 = 13,7%, titik 3 = 17,85%. Sementara itu, pupuk organik yang dibuat, kualitas fisiknya memenuhi standar yaitu berwarna coklat kehitaman, berbau tanah dan teksturnya tidak menggumpal. Untuk hasil uji kadar fosfor (P) dan nitrogen (N) pada pupuk organik diperoleh masing-masing sebesar 22,675% dan 1,76%. Pada pengaplikasian pupuk organik, Tanaman kangkung darat mengalami perkembangan dalam setiap minggu setelah tanam (mst) baik tinggi maupun jumlah daunnya.
