Abstract

Monitoring microclimate conditions, including temperature, humidity, and light intensity, is crucial for maintaining plant health and productivity in vertical indoor hydroponic systems. These conditions directly influence essential physiological processes such as photosynthesis and respiration, affecting growth and yield quality. Manual monitoring methods often suffer from inefficiencies such as slow data collection, operator dependency, and human error. This can delay responses to sudden microclimate changes, leading to plant stress and reduced productivity. This study aims to design a real-time microclimate monitoring and graphical interface system for indoor vertical hydroponics using a User-Centered Design (UCD) approach. The system integrates DHT11 and BH1750 sensors to measure temperature, humidity, and light intensity, respectively, with data processing performed using a Raspberry Pi 3 Model B+. The system performance was evaluated over 24 h using the root mean square error (RMSE) and accuracy metrics. Based on this analysis, the RMSE values for temperature, humidity, and light intensity were 2.398, 1.483, and 392.225, respectively, with an overall accuracy of 97.33%, demonstrating high reliability. Two interface prototypes, Design A and Design B, were developed using distinct visual approaches and evaluated by ten respondents across six criteria: appearance, color, layout, information, icon, and font. Design A outperformed Design B, achieving a higher average score (49 versus 43.4), reflecting its superior clarity and intuitive design. These findings highlight the potential of the proposed system to enhance microclimate management and optimize plant growth in indoor vertical hydroponics.

Abstract

Utilization up-land area for cultivating strategic food crops (paddy, corn and soybean) often neglects the rules of conservation so that it caused surface soil loss by run off. These events can reduce the fertility of agricultural land, so that it results in a decrease in land productivity and finally cause critical lands. Alternative conservation techniques that can be carried out through the application of hydro-mulch and geo-jute combination in order to reduce surface soil loss. The purpose of this study is to examine the use of hydro-mulch and geo-jute in reducing soil loss and observing maize growth as one of the effects of soil loss due to erosion. The treatments given are hydro-mulch, geo-jute and combination of hydro-mulch and geo-jute. The study showed that alternative conservation techniques in the form of hydro-mulch and geo-jute application proved to be able to reduce the amount of soil loss. The combination of hydro-mulch and geo-jute has the ability to reduce the amount of soil loss due to rainfall by 31.51%. Plot with geo-jute treatment can reduce soil loss by 21.86%, and plot with hydro-mulch treatment can reduce soil loss by 11.92%. The hydro-mulch and geo-jute combination can increase the growth of corn. Keywords:  Alternative, Erosion, Geo-jute, Hydro-mulch

Abstract

Hydroponics is an agricultural farming system that does not use soil media but uses water media containing nutrient solutions. The purpose of this research is to measure and observe dissolved oxygen levels in the Smart Watering Unpad and Autopot Systems that have never been done before. The research was conducted using descriptive analysis method that is measuring, observing, calculating, and analysing quantitative data on hydroponic installations Smart Watering Unpad and Autopot. The fertigation used in this study were Smart Watering Unpad and Autopot with the parameters observed were ambient temperature, dissolved oxygen, and the relationship between ambient temperature and Dissolved Oxygen for 30 days of observation. The results showed that the response of dissolved oxygen levels was influenced by environmental temperature in the SWU 01 Lettuce, SWU 02, SWU 03, and SWU 01 Paprika systems had a NEGATIVE relationship direction. The Autopot system is the only installation that has a POSITIVE change in the relationship of dissolved oxygen levels influenced by ambient temperature. Autopot is a hydroponic installation that can maintain the availability of dissolved oxygen levels in the nutrient solution. The Smart Watering Unpad 02 installation can maintain the availability of dissolved oxygen levels in the nutrient solution compared to other installations in the Smart Watering Unpad system type.

Abstract

Cikeruh-Citarik sub-watershed is a part of the upstream zone of the Citarum watershed which is classified as a watershed with critical conditions in West Java. The change in land use as a side effect of the increasing population causes a degradation of the watershed. Land-use change in a watershed without considering any conservation rules leads to erosion, becoming a watershed criticality indicator. Erosion can be minimized by using a prediction model to predict the amount of erosion that might happen, for the result could help to decide which conservation action is needed in the watershed rehabilitation. GeoWEPP is one of the prediction models that is suitable for predicting the amount of erosion on a watershed scale. This research aims to study the preparation of the input data needed in the GeoWEPP model to predict the amount of erosion, especially in the Cikeruh-Citarik sub-watershed. The methodologies that were used in this research are literature study and field survey. According to the research results, the input data needed for GeoWEPP are DEM (Digital Elevation Model) data of the research area, climate database, soil type and soil physical properties database, land use and landcover data, and bridge files for soil, land cover data, and evapotranspiration calculation.

Abstract

Embung Leuwi Padjadjaran II merupakan bangunan penampung air yang berlokasi di Desa Cileles, Jatinangor. Pembangunan embung ini bertujuan untuk menghindari terjadinya banjir saat musim hujan tiba. Namun, keadaan embung mempunyai kenampakan fisik yang buruk. Bagian atas badan air embung dipenuhi dengan tumpukkan tanah. Hal tersebut mengindikasikan adanya erosi yang terjadi di daerah tangkapan air embung. Tujuan dari penelitian ini adalah untuk memetakan sebaran lokasi erosi dan konservasi tanah dan air di Daerah Tangkapan Air Embung Leuwi Padjadjaran II. Erosi yang terjadi pada setiap satuan unit lahan mempunyai tingkat bahaya erosi yang berbeda-beda yang dihitung menggunakan persamaan USLE berdasarkan faktor-faktor erosi. Faktor-faktor erosi tersebut antara lain: faktor erosivitas hujan (R), faktor erodibilitas tanah (K), faktor panjang kemiringan lahan (LS), faktor  pengelolaan tanaman (C) dan faktor pengelolaan konservasi (P). Tingkat bahaya erosi paling dominan di daerah tangkapan air embung adalah tingkat bahaya erosi sangat tinggi (>480 ton/ha/th). Sedangkan, tingkat bahaya terendah dimiliki oleh tingkat bahaya erosi rendah (15-60 ton/ha/th). Konservasi tanah dan air menjadi solusi yang direkomendasikan dalam menanggulangi masalah erosi yang terjadi daerah tangkapan air embung. Penerapan koservasi tanah dan air ditentukan berdasarkan Pedoman Pemilihan Teknologi Konservasi Tanah secara Mekanis dan Vegetatif berdasarkan Tingkat Kemiringan Lahan, Erodibilitas Tanah dan Kedalaman Solum (P3HTA).

Abstract

Indoor vertical hydroponic systems require precise and energy-efficient lighting to support optimal growth of leafy vegetables. This study presents the design and fabrication of a microcontroller-based automatic LED grow light system tailored for indoor hydroponics. A tailored LED grow light is necessary because each crop responds uniquely to light quality and intensity, and a customized spectrum ensures optimal growth while minimizing energy use. The system integrates a red–green–blue LED configuration (70:10:20%) with an ESP32 microcontroller, real-time clock (RTC), BH1750 light sensor, keypad interface, and LCD. The lighting cycle was programmed for 12 hours per day and tested continuously over two days. The system demonstrated accurate scheduling, with LED activation at 06:00 and deactivation at 18:00 and a timing deviation of only 1–2 seconds. During operation, the system maintained a stable photosynthetic photon flux density (PPFD) of 260–275 µmol/m²/s, producing an estimated daily light integral (DLI) of about 12 mol/m²/day, which is suitable for leafy vegetable production. Light distribution analysis using cubic interpolation showed that increasing the lamp height from 20 cm to 30 cm improved spatial uniformity, with the most uniform distribution achieved at 30 cm despite a slight reduction in intensity. The system consumed 2.65 kWh per day, covering four LED arrays and the control module. Overall, the proposed system offers a reliable, programmable, and energy-efficient lighting solution for indoor hydroponic environments, supporting sustainable crop production through precise scheduling and an optimized spectral configuration.
