Abstract

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

Abstract

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.

Abstract

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%.

Abstract

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/).

Abstract

Learning about integrated farming could be done by visiting site locations directly. This is a problem for universities that are located in urban areas. The distance of the integrated agricultural location from the campus often raises a significant cost burden. Therefore, providing a learning model around the university would be more efficient, and students could interact and practice directly. The design concept was compiled based on a literature review. The design was produced by direct observation at Condongcatur experimental garden, then continued SWOT analysis. The design was created using software based on the information gathered. The design development included a general description of the experimental garden, landscape biophysical aspect, concept planning, and design. The resulting design was then validated by experts descriptively using a questionnaire. Meanwhile, user acceptance was measured qualitatively through an interview. Based on the results obtained, theoretically, a small-scale integrated farming design has been successfully compiled and met the requirements to be developed as an agricultural learning model. The design also received a good response from the management, which would then be followed up in the long-term development plan of the experimental garden.

Abstract

Indoor hydroponic systems increasingly utilize IoT technologies for automated nutrient management, yet empirical performance data from extended operational trials remain scarce. This study quantifies control system performance and biological validation for an IoT-based pH-EC control implementation during 35-day continuous operation. The system employed ESP32 microcontroller with safety-based threshold control (pH <8.2, TDS >900 ppm) optimized for reliability rather than precision in a 30L Deep Flow Technique system cultivating 14 pagoda mustard plants. Analysis of 12,219 datapoints revealed TDS control achieved 99.3% time-in-safe-range (MAE 50.06 ppm, settling time 671.6 min) while pH control maintained MAE 0.74 units (settling time 1266.9 min) without exceeding critical thresholds. Plant outcomes validated control effectiveness: final height 20.59 ± 2.03 cm, leaf count 35.50 ± 11.83, with consistent SPAD values >40 indicating adequate nitrogen nutrition despite sub-optimal TDS levels (867 ppm vs. optimal 1050-1400 ppm). Results demonstrate that simplified rule-based control achieves satisfactory biological outcomes when safety thresholds prevent metabolic stress, contributing validated operational benchmarks for resource-constrained hydroponic applications.

Abstract

The Suryo Farmers Group (KT) in Mantrijeron, Yogyakarta City, is a productive community of 26 members. Founded in 2022, the group has demonstrated a strong commitment to utilizing limited land for crops such as mint, lettuce, and cucumbers, and even serves as an agricultural education center. However, its farming development efforts were inhibited by significant failures in hydroponic melon cultivation, with 95% of the crops failing due to disease. Factors contributing to this failure included a damaged greenhouse and members' lack of knowledge regarding cultivation practices, pest and disease management, post-harvest management, and marketing. To address these issues, an integrated community service program was implemented, combining intensive mentoring with knowledge enhancement through a series of outreach and training sessions. The intervention focused on four crucial aspects: proper hydroponic melon cultivation techniques, pest and disease management (PDM), post-harvest handling, and marketing management. The program's effectiveness was measured by comparing quantitative pre-test and post-test results, with a target of a minimum 70% increase in knowledge. The implementation of this activity, involving 26 members, demonstrated significant knowledge gains across all aspects. Data shows a sequential increase in knowledge for Cultivation (from ≈67% to ≈78%), PDM (from ≈63% to ≈85%), Post-Harvest (from ≈83% to ≈93%), and Marketing (from ≈88% to ≈98%). The highest increase occurred in the Marketing and PDM aspects, which directly address the group's main obstacles. The success of this program is expected to be the foundation for KT Suryo Farm to carry out sustainable melon cultivation, produce high-quality products, and implement strong marketing strategies, thereby being able to stabilize and increase the group's turnover.
