Abstract

Pulau Bangka merupakan salah satu pusat pertambangan timah utama di Indonesia, di mana aktivitas pertambangan telah meninggalkan area luas lahan pasca-pertambangan yang sangat terdegradasi. Tanah di area pasca-pertambangan timah ini biasanya telah kehilangan lapisan tanah atasnya, didominasi oleh fraksi pasir kuarsa, kekurangan bahan organik dan nutrisi, memiliki pH asam, dan menunjukkan kapasitas pertukaran kation dan kapasitas penahan air yang sangat rendah, sehingga tidak cocok untuk penggunaan pertanian langsung tanpa upaya rehabilitasi yang terencana. Tinjauan literatur ini bertujuan untuk mensintesis temuan penelitian tentang kondisi tanah, strategi rehabilitasi teknis, dan sistem vegetasi dan tanaman di lahan pasca-pertambangan timah di Pulau Bangka sebagai dasar untuk mengembangkan pertanian berkelanjutan. Metode yang digunakan adalah tinjauan literatur deskriptif-analitis dari 25 publikasi nasional dan internasional yang relevan, dengan data yang disintesis menjadi tiga tema utama: karakteristik tanah, strategi rehabilitasi teknis, dan sistem vegetasi dan tanaman. Hasil menunjukkan bahwa rehabilitasi memerlukan pendekatan bertahap yang mengintegrasikan peningkatan sifat fisik dan kimia tanah melalui penambahan bahan organik lokal, pembentukan kontur lahan, dan pengelolaan nutrisi, bersamaan dengan penggunaan vegetasi toleran dan sistem tanaman adaptif. Sistem tumpang sari tanaman polong-polongan dan tanaman pangan, pengembangan tanaman pakan ternak, dan komoditas bernilai tinggi memiliki potensi ganda sebagai agen rehabilitasi biologis dan sumber produksi. Tinjauan ini menggarisbawahi pentingnya kerangka rehabilitasi terpadu yang menggabungkan perbaikan tanah dan desain sistem penanaman untuk mendukung pemanfaatan lahan pasca penambangan timah secara berkelanjutan di Pulau Bangka dan berfungsi sebagai dasar untuk merumuskan agenda penelitian di masa mendatang.

Abstract

This research aims to design and develop an Internet of Things (IoT)-based automatic control and monitoring system for hydroponic plants. This system measures, displays, and regulates nutrient parameters, pH, and water volume in real-time to improve water use efficiency, nutrient stability, and plant productivity. The method used is Research and Development (R&D) with a prototyping model. This system integrates an ESP32 microcontroller with a DFRobot pH sensor, a TDS (Total Dissolved Solids) sensor, and an ultrasonic sensor to monitor water levels. Data from the sensors is processed and sent to a cloud database to be monitored and controlled through a website interface. The test results show that the system has high accuracy, with a MAPE (Mean Absolute Percentage Error) value for the pH sensor of 6.06% (93.94% accuracy), a TDS sensor of 4.81% (95.19% accuracy), and an ultrasonic sensor of 7.98% (92.02% accuracy). All MAPE values ​​are within the <10% range, indicating good system performance for automated monitoring applications. This system implementation provides an innovative solution to the limitations of conventional, manual hydroponic systems. It can serve as an initial model for the future development of IoT-based precision agriculture.

Abstract

Interest in science and agriculture among Indonesian high school students tends to decline due to theoretical biology instruction lacking contextual real-world applications, making it difficult for students to connect vegetative propagation concepts with practical uses. This community service program aims to foster students' interest, motivation, and skills through hands-on vegetative plant propagation education while establishing sustainable university-school partnerships for practice-based learning. Conducted as a one-day experiential learning workshop on November 14, 2025, at SMA YPK Air Kenanga, Bangka, the activity engaged 30 class XI students across five sequential stages: aseksual vegetative propagation concept introduction, planting media preparation (60 polybags with soil-compost mix), demonstration of cacao-avocado cuttings-budding-grafting techniques, guided hands-on practice, and post-propagation care instruction. Multi-indicator evaluation included Kahoot! pre/post-tests, psychomotor checklists by two independent observers, and satisfaction questionnaires. Results revealed 72.7% cognitive knowledge improvement (39.37% to 68.01% correct answers), 93% practice success rate (56 successful vegetative plants), 100% post-propagation care comprehension, and 85% student satisfaction. The program effectively bridged biology theory with local horticulture applications, created sustainable impact through 3-month monitoring, and offers replication potential across 5 Bangka high schools to strengthen sustainable agriculture curricula in agrarian regions.
