Abstract

Plant nutrition and water provision are very important for plant growth and development. Nutrition can be done with AB mix nutrition with a certain concentration while the frequency of water can be controlled with a microcontroller. The purpose of this study was to examine the effect of various concentrations of AB mix nutrients and the frequency of irrigation water using a microcontroller on the yield of mustard greens. This research can be useful as a source of information related to the application of microcontroller sensors in the provision of appropriate AB mix water and nutrition for farmers and practitioners. The research design consisted of two treatments, namely the concentration of AB mix and the frequency of water administration with 3 repetitions. the concentration of AB mix nutrients given consisted of three variations, namely 750 ppm (D1), 1250 ppm (D2), and 1750 ppm (D3) while the frequency variations consisted of variations of 4x water administration (F1), 8x water administration (F2), and 12x water administration (F3). The volume of water has increased by three stages from the beginning of planting to harvest. The results showed that the AB mix concentration treatment showed a significant difference to plant fresh weight but not to other parameters. The frequency of water treatment also showed the same results as the nutrient concentration treatment and there was no interaction between the frequency of water treatment and the AB mix concentration. Furthermore, the best variation is the variation of nutrition 1750 ppm and the frequency of 8x watering.

Abstract

Selada hijau merupakan tanaman hortikultura yang banyak dibudidayakan di Indonesia. Nilai ekspor tanaman selada setiap tahunnya berfluktuasi dan cenderung menurun, bahkan pada tahun 2019 terdapat impor tanaman selada di Indonesia. Adanya impor dan menurunnya ekspor tanaman selada menunjukkan bahwa perlu adanya perbaikan dalam budidaya tanaman selada di Indonesia agar produktivitasnya meningkat dan dapat memenuhi kebutuhan pasar dengan cara mengubah teknik budidaya dari konvensional menjadi modern (hidroponik). Permasalahan yang terdapat pada budidaya selada hidroponik yaitu kurangnya kecukupan nutrisi sehingga tanaman mengalami gejala seperti batang dan daun tanaman yang lemah dan mudah rebah, serta mengalami klorosis. Hal tersebut dapat diatasi dengan pemberian unsur kalium dan nitrogen dalam bentuk KNO3. Rancangan penelitian yang digunakan yaitu Rancangan Acak Lengkap (RAL) dengan satu faktor yaitu konsentrasi KNO3 yang terdiri dari 606 ppm, 808 ppm, 1.010 ppm, dan 1.212 ppm serta diulang sebanyak 5 kali. Parameter yang diamati yaitu berat basah tajuk tanaman, tinggi tanaman, jumlah daun, luas daun, kandungan klorofil, nisbah akar tajuk, laju pertumbuhan tanaman, uji organoleptik, dan serapan K tanaman. Penelitian dilakukan di Greenhouse Agrotechnopark Universitas Jember pada Bulan Desember – Februari. Analisis data menggunakan ANOVA dan diuji lanjut menggunakan DMRT 5%. Konsentrasi KNO3 memberikan hasil yang berbeda nyata pada tinggi tanaman, jumlah daun tanaman, kandungan klorofil, luas daun, berat basah tajuk, laju pertumbuhan tanaman, nisbah akar tajuk, dan serapan kalium tanaman. Konsentrasi kalium nitrat sebesar 1.010 ppm memberikan hasil terbaik dengan meningkatkan pertumbuhan jumlah daun tanaman sebesar 25.88% dan meningkatkan hasil berat basah tajuk tanaman sebesar 64,89% dari konsentrasi kalium nitrat sebesar 606 ppm.

Abstract

The critical phase of rice plants on water availability includes the vegetative phase when tillering stage, generative phase 1 at panicle initiation stage and generative phase 2 when booting stage. The lack of water in the vegetative phase and in the generative phase will disturb the growth of rice plants. However, if the water needs are fulfilled immediately, the plants will recover and able to grow normally. The ability of plants to do recovery can be improved through the application of potassium fertilizer. This research aimed to determine the optimum dosage of potassium fertilizer when drought occurs in several critical phases to improve the recovery capability of the rice plant. This experiment used a completely randomized design (CRD) with 2 factors where the first factor was the dosage of potassium fertilizer using KCl fertilizer which was 50 kg/ha, 75 kg/ha, 100 kg/ha and 125 kg/ha. The second factor was the difference in the phase of stress, namely the vegetative phase at the time of tillering, the generative phase 1 at panicle initiation and the generative phase 2 when booting. Each treatment combination was repeated 3 times. Observation variables included Rice grain weight per clump, Proline content, Root Dry Weight, Relative Water Content (RWC) leaves, and Height of plants. The results of the study proved that the best dosage of KCl fertilizer to improve rice recovery ability is 100 kg/ha. Rice plants gripped in the vegetative phase have better recovery capabilities than those gripped in the generative phase.Keywords: Recovery, rice, drought stress and potassium.

Abstract

Proses penguraian sampah organik dengan biokonvertor Black Soldier Fly (BSF) dilakukan pada tahap larva, sehingga saat BSF menjadi lalat dewasa, bertelur dan mati akan meninggalkan limbah media bekas maggot, cangkang pupa dan bangkai lalat. Limbah media bekas maggot digunakan untuk bahan kompos, sedangkan limbah cangkang pupa dan bangkai lalat belum dimanfaatkan. Timbunan limbah cangkang pupa dan bangkai lalat setelah siklus hidup BSF dikhawatirkan bisa menimbulkan pencemaran udara dan lingkungan jika dibiarkan menumpuk di halaman rumah. Berdasarkan analisis situasi tersebut, tim ProbangDebi UNEJ bersama Bank Sampah Ekoliterasi Dermaku Jenggawah merancang kegiatan yang bertujuan untuk memberikan edukasi tentang teknologi pengolahan limbah cangkang pupa agar memiliki nilai ekonomi. Metode pelaksanaan kegiatan adalah edukasi potensi limbah cangkang pupa BSF dan pelatihan teknologi pengolahan limbah cangkang pupa BSF. Data pre-test dan post-test menunjukkan bahwa terjadi peningkatan pengetahuan pembudidaya maggot di Desa Jenggawah tentang pemanfaatan limbah cangkang pupa BSF menjadi produk yang memiliki nilai tambah. Pengolahan limbah cangkang pupa BSF dapat ditingkatkan kapasitasnya menjadi skala yang lebih besar lagi seiring dengan peningkatan kebutuhan pasar dalam pemanfaatan kitin dan kitosan. Selanjutnya, dibutuhkan pelatihan pemasaran melalui platform e-commerce dan koordinasi lintas sektoral untuk memberikan dukungan atas upaya pengolahan limbah menjadi produk yang bermanfaat bagi kesejahteraan dan perekonomian masyarakat. Kata kunci— Black Soldier Fly, Budidaya Maggot, Cangkang Pupa, Kitin, Kitosan Abstract The process of decomposing organic waste using the Black Soldier Fly (BSF) bioconverter is carried out at the larval stage. BSF becomes adult flies, lay eggs and die, which will leave maggot cultivation media, pupa shells and fly carcasses. Maggot cultivation media is used as compost material, while pupa shells and fly carcasses have not been utilized. Piles of pupa shells and fly carcasses can cause air and environmental pollution. The ProbangDebi UNEJ team and the Dermaku Jenggawah Ecoliteracy Waste Bank designed activities aimed at providing education on pupa shell processing so that it has economic value. The implementation method is education and training on BSF pupa shell processing technology. Pre-test and post-test data show that there has been an increase in the knowledge of maggot cultivators in Jenggawah Village regarding the use of BSF pupa shells into products that have added value. BSF pupa shell processing capacity can be increased to a larger scale in line with increasing market demand for the use of chitin and chitosan. Furthermore, marketing training through e-commerce platforms and cross-sectoral coordination is needed to provide support for efforts to process waste into products that are beneficial for the welfare and economy of the community. Keywords— Black Soldier Fly, Chitin, Chitosan, Maggot Cultivation, Pupa Shell
