Abstract

Abstract – SD Negeri 12 Padang Panjang is one of the schools that has made efforts to implement the Adiwiyata program. In 2024, the school represented the city of Padang Panjang in the Adiwiyata competition at the West Sumatra provincial level; however, it did not achieve optimal results. For the 2025 Adiwiyata program, SD Negeri 12 has set a target to become the provincial representative of West Sumatra. Based on the evaluation results from 2024, it was found that the assessment indicator for Participatory-Based Environmental Activities needs improvement. One activity that can support this effort is hydroponic cultivation. A hydroponic cultivation training was conducted by 26 fifth-grade students. The training included both theoretical material and hands-on practice in cultivating green vegetables using a hydroponic system. The training was guided by two experts who are competent in the field. This training successfully increased students' knowledge of hydroponic vegetable cultivation. Moreover, over 90% of the participants demonstrated teamwork and developed a greater awareness of environmental care. This outcome is a significant contribution to supporting SD Negeri 12 Padang Panjang Barat’s efforts toward achieving Adiwiyata School status.

Abstract

Lettuce (Lactuca sativa L.) is a vegetable commodity that is currently in high demand because it has many health benefits. Hydroponic cultivation is a method that can improve lettuce growth by utilizing IoT based pH and TDS sensors. This study aims to compare lettuce growth in hydroponic cultivation by applying Internet of Things (IoT)-based pH and TDS sensors and manual methods. The method used was an experimental method by comparing the average of two treatments, namely the use of IoT-based pH and TDS sensors and the manual method, with each treatment consisting of nine replicates. The results showed that the application of IoT sensors had a significant effect on increasing plant height, leaf area, wet weight, and dry weight. IoT technology can improve efficiency and productivity in hydroponic systems because the sensors can maintain a stable balance of nutrients and acidity in the solution, resulting in better plant growth. These findings indicate that the application of IoT has great potential in supporting sustainable agriculture, while also providing benefits in the form of increased production efficiency and resource savings.

Abstract

The macadamia plant (Macadamia integrifolia) is a high-quality nut-producing commodity with significant economic value; however, conventional propagation still faces limitations in producing superior seedlings in large quantities that are uniform and sustainable. This internship activity aimed to study the procedures for in vitro macadamia tissue culture, from the preparation of Murashige and Skoog (MS) medium, sterilization of explants, tools, and materials, incubation, to subculture. The activity was carried out at the UPTD Balai Sertifikasi dan Perbenihan Tanaman Hutan (BSPTH) Dinas Kehutanan Provinsi Sumatera Barat from January 5 to February 15, 2026. The explants used were young shoots of macadamia plants grown on MS medium supplemented with the plant growth regulator BAP. A total of 81 explants were observed during the culture process. The observations showed that 34 explants (41.98%) grew successfully without contamination, whereas 47 explants (58.02%) experienced fungal and bacterial contamination as well as browning. The high level of contamination was presumed to be related to the presence of endophytic contaminants, the suboptimal sterilization protocol, and the condition of explants originating from open field conditions. Browning can be managed through the addition of antioxidants, such as PVP, activated charcoal, and ascorbic acid, to the medium. This activity confirms that tissue culture has the potential to become an alternative method for macadamia propagation, but its success is highly dependent on the optimization of explant sterilization and the control of tissue browning. The implications of this activity point to the need for implementing staged sterilization and conditioning mother plants in a greenhouse to improve the success of macadamia micropropagation in subsequent studies.

Abstract

Bamboo plants (Bambusa sp.) have high economic and ecological value; however, conventional propagation still faces limitations in producing uniform, high-quality, and disease-free seedlings. This activity aimed to study the stages of bamboo tissue culture, including the preparation of MS medium, explant sterilization, inoculation, incubation, subculture, and acclimatization. The internship activity was carried out from January to February 2026 at the UPTD BSPTH Dinas Kehutanan Provinsi Sumatera Barat. Data were obtained through observations of the bamboo tissue culture process at each stage and were then analyzed descriptively based on the success of explant growth and the constraints that emerged during the culture process. The results of the activity showed that some explants grew successfully, whereas others experienced browning and contamination. The success of bamboo tissue culture was influenced by the accuracy of sterilization, medium composition, the use of plant growth regulators, and incubation conditions. The conclusion of this activity affirms that tissue culture techniques have the potential to become an effective alternative for mass propagation and conservation of bamboo germplasm. Its implications indicate that the optimization of sterilization procedures, medium formulation, and culture condition regulation needs to be carried out continuously to improve the success of in vitro bamboo propagation.
