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.

Abstract

The principles of chemistry learning emphasize that students study chemical concept in a structure and detailed manner. Until now, chemistry lessons are still a big challenge for teachers, because students often experience difficulties when learning chemical concept such as the concept of stoichiometry. This study aims to determine the level of concept understanding and the percentage of students' concept understanding on stoichiometry material using a five tier diagnostic test. The method used in this research is descriptive qualitative. The results showed: (1) the average level of students' concept understanding is classified in the category of lack of knowledge (LK); (2) the average percentage of students who understand the concept (SC) is 13.0% and the sub-concept with the highest percentage of understanding the concept (SC) is Relative Molecular Mass which is 33.0%. Of the 15 questions tested, question number 1 has the highest percentage of understanding the concept (SC) of 33.0%, while for the other 14 questions the average student is classified in the category of lack of knowledge (LK). It can be concluded that students' concept understanding on stoichiometry material is still classified as very low criteria.
