One aspect of success in aquaponic cultivation is a suitable installation to support the growth of plants and fish. Good nutritional water quality is needed in aquaponic cultivation for the survival of fish and plants. Aquaponic systems could use several systems to deliver nutrients or water to plants. One system that could be used is the DFT (Deep Flow Technique) system. The DFT system for simple aquaponics requires a design and its implementation in the yard. So, in this article, the design and implementation of a DFT system for simple aquaponics in the yard were discussed. The design results have been successfully realized. DFT aquaponic trials on rice-tilapia plants resulted in normal growth of plants and fish even though harvest data were not recorded. Subsequent trials on DFT aquaponic vegetable- catfish produced an average wet weight per plant for the Grand Rapids lettuce was 15,526 gr, Red Rapids was 60,916 gr, Green romaine was 48,630 gr, and star lettuce was 33,106gr. Meanwhile, the average yield obtained from the Tosakan variety was 31,466 gr per plant, Shinta was 38,576 gr, New White Light was 10,116 gr, and Chinese Kale New Veggin was 18,678 gr/plant. Catfish harvested were 100 - 200g per fish with SR value> 80%.

Phytoremediation is usually applied to passively treat Acid Mine Drainage (AMD) by constructing a wetland. To increase the success of the AMD treatment method, laboratory trials were carried out on a pilot scale, and the experimental results were applied on an actual scale. Therefore, a simple design will be prepared for this research that replicates the wetland work system. This research aimed to produce a prototype that could be used for initial testing of phytoremediation on a smaller scale before being applied to field conditions. The installation design was created using Adobe Illustrator software. The trial lasted two months, using modified acid water and flowing it periodically as controlled droplets via an infusion tap into the media that used Typha sp and Pistia stratiotes L as phytoremediator agents. This equipment was tested with three acidity levels, 4, 5, and 6, repeated twice for two months. Results showed that the prototype was built using three buckets arranged in layers, each with its function. The phytoremediation process had successfully occurred in this study, and installation was suitable to support the process. There was a change in AMD acidity around the plants for five weeks and an increase in acidity the fourth week after treatment at the outlet. It could be seen that AMD with lower acidity levels resulted in greater plant damage in the sixth week, but Typha sp still showed resistance to an acidic environment.

The Surya Makmur Farmers Group, formed in 2023 in Suryowijayan Village, Yogyakarta, consists of 20 housewives who were previously not economically productive. This urban farming program aims to increase household food security through training in modern agricultural technology such as vertical farming, tabulampot, organic fertilizers, and botanical pesticides. Demonstration plots (demplots) with smart plug-based drip irrigation were also developed to increase cultivation efficiency. This program has increased production by up to 50% in several commodities such as chilies, mustard greens, and corn. In addition, member empowerment has increased through institutional training and organic waste management. This program creates a sustainable impact on food security and community welfare.ABSTRAKKelompok Tani Surya Makmur, dibentuk pada tahun 2023 di Kampung Suryowijayan, Yogyakarta, beranggotakan 20 ibu rumah tangga yang sebelumnya tidak produktif secara ekonomi. Program urban farming ini bertujuan meningkatkan ketahanan pangan rumah tangga melalui pelatihan teknologi pertanian modern seperti vertikultur, tabulampot, pembuatan pupuk organik, dan pestisida nabati. Demonstration plot (demplot) dengan irigasi tetes berbasis smart plug juga dikembangkan untuk meningkatkan efisiensi budidaya. Program ini berhasil meningkatkan produksi hingga 50% pada beberapa komoditas seperti cabai, sawi, dan jagung.

Soybean production in Indonesia currently does not meet national demand. However, there is potential to increase production by utilizing sub-optimal lands, such as Regosol soils. Regosol soils are characterized by a high sand content, low fertility, and poor water-holding capacity, which exposes plants to drought stress. To enhance soybean productivity under such conditions, technological innovations are needed, including the use of biofertilizers and nanotechnology. The Anjasmoro soybean variety is known to be relatively sensitive to drought stress. The application of Plant Growth-Promoting Rhizobacteria (PGPR) and nanosilica is expected to improve nutrient uptake, stimulate the production of growth-promoting hormones, and enhance plant tolerance to drought stress. This study aimed to evaluate the growth and yield of the Anjasmoro soybean variety in response to PGPR and nanosilica fertilization. A factorial Completely Randomized Design (CRD) was employed, consisting of nanosilica concentrations (0, 100, and 200 ppm) and PGPR concentrations (0, 5, 10, and 15%). The results indicated that PGPR and nanosilica fertilization improved soybean tolerance to drought stress. The most effective treatment for enhancing the growth and yield of the Anjasmoro soybean variety on Regosol soil was the application of 10% PGPR combined with 200 ppm nanosilica. This treatment significantly increased pod number, pod weight, 100-seed weight, fresh shoot weight, dry shoot weight, fresh root weight, and chlorophyll content. Additionally, the application of 5% PGPR combined with 200 ppm nanosilica resulted in the best seed quality

Smart farming technology was previously implemented at Wedomartani experimental station, Faculty of Agriculture UPN "Veteran" Yogyakarta. It is proven to overcome human resource limitations in hydroponic cultivation. Even so, Smart farming has not been implemented yet in Pyramid Greenhouse, Which is the iconic landmark of the Faculty of Agriculture. Preparing IoT-based devices requires designs with certain specifications. Without an appropriate design, it would be found a failure system. This article’s purpose was to design an Internet of things (IoT) based hydroponic controlling device in Greenhouse Pyramid UPN “Veteran” Yogyakarta. It was built based on a literature study. Expert proofing was performed to ensure the design would work if implemented. The design contained the system overview, hardware description, user interface design, and integration of device system design in hydroponic installations. The design was positively accepted by users (Head of the experimental field and technicians). In the future, the proposed design needs to be realized as a part of greenhouse development.

Kelapa sawit merupakan tanaman perennial yang membutuhkan ketercukupan nutrisi sepanjang tahun. Penyediaan nutrisi tanaman melalui pemupukan harus sesuai dengan kebutuhan spesifik kelapa sawit. Pengetahuan tentang jenis pupuk, perhitungan dosis, dan penaksiran karakteristik iklim sangat mempengaruhi efektivitas dan efisiensi pemupukan. Penentuan rekomendasi pemupukan melalui analisis tanah dan daun seringkali tidak dapat dilakukan oleh petani akibat faktor biaya dan pengetahuan yang terbatas. Penentuan jenis, dosis, dan waktu pemupukan ditentukan oleh factor internal dan eksternal tanaman. Pembangunan sistem rekomendasi melibatkan 3 domain pengetahuan pemupukan kelapa sawit, yaitu domain tanah, tanaman, dan iklim. Perhitungan kebutuhan nutrisi didasarkan pada defisit antara unsur pemasok dan unsur penghilang nutrisi pada agroekosistem kelapa sawit. Langkah penentuan dosis pupuk diawali dari perhitungan defisit nutrisi, identifikasi jenis pupuk penyuplai nutrisi, penentuan aturan matematis, dan penentuan waktu pemupukan berdasarkan data iklim. Sistem rekomendasi pemupukan kelapa sawit ditampilkan dengan format antarmuka berupa website (http://smartferti.com/).
