Abstract

Abstrak. Pembibitan menggunakan polybag dapat digantikan dengan biopot yang dapat langsung ditanam bersama bibit saat transplanting, sehingga tidak merusak perakaran, serta baik untuk adaptasi bibit di lingkungan yang baru. Penelitian ini bertujuan untuk melakukan optimalisasi komposisi pada pembuatan biopot berbahan dasar ampas kelapa untuk meningkatkan sifat fisik–mekanik biopot serta pertumbuhan bibit cabai. Rancangan percobaan pada penelitian ini berupa Rancangan Acak Lengkap (RAL). Terdapat 4 perlakuan perbandingan massa bahan ampas kelapa dan lem sagu, yaitu AK-A (1 : 1); AK-B (1 : 1,25); AK-C (1 : 1,5); serta AK-D (1 : 1,75). Pengamatan yang dilakukan berupa sifat fisik-mekanik biopot serta pertumbuhan bibit. Hasil penelitian menunjukkan bahwa perlakuan memberikan pengaruh terhadap sifat fisik-mekanik biopot. Hasil uji Duncan menunjukkan perlakuan AK-D adalah perlakuan dengan bobot, densitas, dan kemampuan menahan gaya luar tertinggi, serta yang paling rendah indeks penyerapan air dan kadar air biopotnya. Hasil ini mengkonfirmasi bahwa perlakuan AK-D merupakan perlakuan terbaik ditinjau dari sifat fisik-mekanik biopot yang dihasilkan. Perlakuan AK-D menghasilkan bobot, densitas, dan kemampuan menahan gaya luar tertinggi, masing-masing sebesar 70,33 g; 500,41 kg/m3; dan 138,33 N, dengan kadar air dan daya serap air terendah yaitu 11,51% basis basah dan 52,89%. Adapun parameter pertumbuhan tanaman tidak berpengaruh nyata untuk tiap perlakuan Kata Kunci: Bibit, Biopot, Organik, Polybag, Sagu

Abstract

The research aims to develop media, validity and see students' responses to the application of mini hydroponics simulator learning media based on microcontrollers with the addition of LED grow lights in SMK. The type of research used is research development (Research and Development). Efforts to develop instructional media to meet the needs of students at the vocational level, it is necessary to flow the research process using the ADDIE development model, covering 5 stages in its implementation, namely analysis, design, development, implementation, and evaluation . The object of the research is a mini hydroponic simulator based on a microcontroller with the addition of led gow light which has been validated by media and material experts. Validation by media experts is carried out to assess and provide input to the media and validation by material experts is carried out to assess and provide input to the media usage manual. The research respondents consisted of 25 students. The instrument used for data collection was the use of a questionnaire. The measurement scale of the data uses a Likert scale and the activity of data analysis is done by finding the percentage (%) of validity and response of students. The results showed that the development of the simulator included the addition of led grow light components, light sensors, active buzzers and a more flexible construction. Through the application of simulators, students gain new knowledge about more modern hydroponic cultivation. Simulator validation conducted by media experts obtained a percentage value of 92%, which means that it was very valid to be used, while the validation of the manual that was done by material experts obtained a percentage value of 94.1%, which means it was very valid. Student responses to the simulator showed a percentage of 87.25% which means there is a very positive response to the application of the simulator in the learning process.
