Riwayat Artikel : Diterima : 2 November 2020 Disetujui : 1 Februari 2021 Aquaponik merupakan salah satu cara budidaya tanaman dengan hidroponik bersamaan dengan budidaya ikan, dimana air berputar terus tanpa berhenti. Pada sistem aquaponik tidak memerlukan nutrisi AB mix untuk memberikan unsur hara pada tanaman, tetapi unsur hara diperoleh dari air kolam ikan yang mengandung nutrisi, yang berasal dari ikan. Selada (Lactuca sativa L.) yang ditanam secara hidroponik merupakan sayuran yang digemari karena harganya tinggi dan sehat untuk dikonsumsi. Tujuan dari penelitian ini adalah untuk mengetahui adanya tidaknya perbedaan hasil budidaya tanaman selada secara aquaponik menggunakan tiga model hidroponik DFT. Metode yang digunakan adalah pengukuran lapangan, yang meliputi tinggi tanaman, jumlah daun, dan berat tanaman selada, serta analisis data hasil pengukuran. Selain itu juga dilakukan pengukuran suhu, pH dan konsentrasi air kolam, serta kandungan amonia pada air kolam. Hasil pengukuran lapangan dengan hidroponik DFT model meja, model piramida, dan model anak tangga dianalisis untuk mengetahui apakah terdapat perbedaan menggunakan Anava (Analisis Varians) satu jalan pada taraf signifikansi 5%. Berdasarkan Anava diketahui bahwa terdapat perbedaan hasil pengukuran tanaman selada dengan menggunakan ketiga model hidroponik DFT, dan yang berpengaruh paling baik adalah model piramida, dengan hasil rata-rata 21,8 cm untuk tinggi tanaman, rata-rata 8,4 helai untuk jumlah daun, dan rata-rata 75,3 g untuk berat tanaman. Kata Kunci : Aquaponik, Hidroponik DFT, Selada.

Perovskite single-crystal arrays have attracted intensive attention because of their great potentials for integrated optoelectronic devices. However, the traditional top-down lithography strategy requires complex processing and is detrimental to perovskite crystal structures, which is incompatible to directly pattern perovskite single crystals. Herein, we report a lithography-free method to realize the controllable growth of perovskite single-crystal arrays. Through introducing a printed hydrophilic-hydrophobic substrate into the crystallization system, the MAPbCl 3 single-crystal arrays with precise location and uniform size are effectively fabricated. This method can be applied to prepare diverse perovskite single-crystal arrays, including MAPbBr 3 , CsPbCl 3 , CsPbBr 3 , Cs 3 Cu 2 I 5 , Cs 3 Bi 2 I 9 and (BA) 2 (MA) 3 Pb 4 I 11 . The perovskite single crystals can be selectively grown on the electrodes to fabricate ultraviolet photodetectors. The strategy demonstrates a facile approach to fabricate large-scale perovskite single-crystal arrays and opens a pathway to produce diverse perovskite optoelectronic devices.

A colorimetric liquid sensor based on a poly(vinyl alcohol)/silver nanoparticle (PVA/AgNPs) hybrid nanomaterial was developed for gamma radiation in the range of 0–100 Gy. In this study, gamma rays (Cobalt-60 source) triggered the aggregation of AgNPs in a PVA/silver nitrate (AgNO3) hybrid solution. The color of this solution visibly changed from colorless to dark yellow. Absorption spectra of the PVA/AgNPs solution were analyzed by UV-Vis spectrophotometry in the range of 350–800 nm. Important parameters, such as pH and AgNO3 concentration were optimized. The accuracy, sensitivity, stability, and uncertainty of the sensor were investigated and compared to the reference standard dosimeter. Based on the spectrophotometric results, an excellent positive linear correlation (r = 0.998) between the absorption intensity and received dose was found. For the accuracy, the intra-class correlation coefficient (ICC) between the PVA/AgNPs sensor and the standard Fricke dosimeter was 0.998 (95%CI). The sensitivity of this sensor was 2.06 times higher than the standard dosimeter. The limit of detection of the liquid dosimeter was 13.4 Gy. Moreover, the overall uncertainty of this sensor was estimated at 4.962%, in the acceptable range for routine standard dosimeters (<6%). Based on its dosimetric performance, this new PVA/AgNPs sensor has potential for application as an alternative gamma sensor for routine dose monitoring in the range of 13.4–100 Gy.
