Abstract

River water quality is typically monitored using sampling methods. This approach makes detecting water pollution challenging owing to the limited sampling time. Another factor influencing water quality is weather, which can be addressed by incorporating weather station sensors as corrective tools. The collected data were processed and visually displayed to make the important information easily interpretable. The water quality parameters measured in this study included Electrical Conductivity (EC), temperature, Total Dissolved Solids (TDS), salinity, pH, turbidity, Dissolved Oxygen (DO), and saturation. The weather parameters measured by the system included wind speed, wind direction, air temperature and humidity, atmospheric pressure, rainfall, and solar radiation. The system's capabilities include data transmission via cellular networks, data backup using an SD card, and industrial sensors with IP (Ingress Protection) standards that utilize the Modbus RS485 protocol. The study followed the Software Development Life Cycle (SDLC) or waterfall method to ensure system readiness and durability in real-world environments. The Modbus RS485 protocol allows multiple sensors to share a single cable line, resulting in a more efficient and less complex wire arrangement. These findings highlight the necessity of separating sensor lines based on parity type and baud rate for each sensor, enabling simultaneous readings in subsequent operations.

Abstract

Conventional fish hatchery faces many challenges, such as extensive land use, excessive water use, environmental pollution, and a controlled maintenance system, making the fish hatchery process inefficient. The development of a Controlled Water Recirculation System (SRAT) can be a solution to overcome this problem. This study aims to obtain a water balance model and determine the amount of pressure loss that occurs in the SRAT piping network to improve the performance of SRAT by maintaining the uniformity of water discharge in each water tank in the SRAT. First, the average discharge was 2,134 L/min, with a uniformity of only 79%. After the intervention of the model, the uniformity value increased to 99% with an average of 1,269 L/min. It can be concluded that the built model can maintain the uniformity of water discharge in each tub contained in the SRAT.

Abstract

Salah satu faktor penting dalam menunjang keberhasilan peningkatan produksi pertanian adalah penggunaan alat dan mesin pertanian. Berkurangnya tenaga kerja, sempitnya lahan sawah, sawah dalam tanpa lapisan tanah keras (hardpan) akan menyulitkan alat dan mesin pertanian untuk bekerja. Daya dukung tanah adalah kemampuan tanah dalam menahan beban alat dan mesin yang bekerja diatasnya. Tekanan tanah yang diakibatkan oleh aktivitas kerja alat dan mesin pertanian menyebabkan tidak semua alat dan mesin pertanian dapat bekerja di sawah sama baiknya dengan di darat. Berdasarkan permasalahan tersebut maka penelitian ini dirancang untuk mengetahui pengaruh nilai daya dukung tanah terhadap jenis mesin pertanian yang dapat diaplikasikan diatasnya. Pengukuran nilai daya dukung tanah diukur pada 3 kategori lahan. Analisis dilakukan dengan membandingkan nilai tahanan penetrasi tanah dengan indeks trafficability traktor. Penelitian ini dilaksanakan pada bulan Februari hingga Juli 2024. Dari penelitian diketahui bahwa mesin pertanian bertipe traktor roda 4 dan combine harvester tidak dapat diaplikasikan pada lahan sawah yang menjadi sampel pengukuran di Kabupaten Kulon Progo. Apabila diaplikasikan maka combine harvester dan traktor roda 4 akan mengalami ketenggelaman (sinkage) lebih dari 15 cm untuk lahan kategori 1 dan 2, serta akan mengalami ketenggelaman (sinkage) lebih dari 20 cm untuk lahan kategori 3.

Abstract

Maintaining an optimal microclimate is essential for efficient operation of tropical greenhouses, particularly under fluctuating weather conditions. This study proposes an adaptive energy-efficient model for regulating air temperature in tropical greenhouses using historical climate data. The model optimizes the fan rotation speeds via an inverter to meet the temperature targets while minimizing energy consumption. Key methodologies include climate data analysis, development of a predictive model for indoor air temperature using Artificial Neural Networks, and optimization of fan speed control. The model achieved high predictive accuracy, with an RMSE of 0,02 and an R² of 0,96. The practical implementation demonstrated effective temperature control, with fan speeds ranging between 30 and 40 Hz during cloudy periods and 50 Hz in sunny conditions. Notably, the system reduced electricity consumption by 33,93% during cloudy weather and 18,54% in sunny weather, showing its potential for significant energy savings. This data-driven adaptive model approach is highly suited for tropical greenhouses experiencing dynamic climatic variations and offers a sustainable and efficient solution for greenhouse microclimate management.

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

Tempe is a nutritious food that is popular with many people. The problem is that tempe has a short shelf life and must be consumed immediately. Instant tempe is one of the innovative tempe products with a longer shelf life. This research aims to analyze the shelf life of instant tempe in various packages and at different storage temperatures using the Arrhenius model. The method used in this research was laboratory experimental, using 378 samples of instant tempe which were packaged in vacuum packaging, non-vacuum packaging, and cup packaging, and stored at cold temperature (12°C), room temperature (27°C), and hot temperature. (35°C). There are nine treatment combinations regarding the relationship between packaging and temperature, each treatment is carried out 3 times. Measurements for each treatment are carried out until the instant tempe cannot ferment to become tempe ready for consumption. This shows that the fungus Rhizopus oligosporus has died. The research results show that the CIE L* value of instant tempe decreases as the storage period for instant tempe increases. The shelf life of estimation results using the Arrhenius model for vacuum packaging and storage temperatures of 12°C, 27°C, and 35°C respectively is 36.98 days, 6.88 days, and 3.00 days. The use of non-vacuum packaging and storage temperatures of 12°C, 27°C, and 35°C were respectively 15.84 days, 5.63 days, and 2.38 days. In comparison, the use of cup packaging and storage temperatures of 12°C, 27 °C, and 35°C respectively are 17.62 days, 6.31 days, and 2.80 days.

Abstract

Fake palm oil seeds pose a substantial economic threat, which makes their authentication crucial. However, distinguishing between genuine and fake seeds remains a challenge. This study explored the potential of ultrasonic technology to measure shell thickness as a distinguishing factor based on the reported variations between the two types. Ultrasonic wave measurement software was developed using Arduino Uno to facilitate the analysis. The results highlight the complexity of accurately measuring the seed shell thickness owing to high attenuation. Micro-CT imaging confirmed the presence of pores within the seed structure, which significantly scattered and absorbed ultrasonic waves, limiting the penetration depth and accuracy. Despite these obstacles, the developed software exhibited promising capabilities, accurately determining the thickness or propagation speed with a high-resolution time-of-flight measurement of up to 62.5 nanoseconds. Additionally, the software is capable of sampling ultrasonic signals at frequencies up to 178 kHz. Although the software performs well under specific conditions, further advancements in ultrasonic technology are necessary to mitigate porosity-related limitations and enhance the effectiveness of seed authentication methods, particularly in transducer selection and measurement techniques such as Harmonic or QSC testing.

Abstract

Biochar from agricultural waste has many applications in the field of agricultural and wastewater treatment. In this study, biochar derived from exhausted kahwa coffee (EKC) was produced at low carbonization temperatures (200–400°C) for the removal of copper (II) ions (Cu2+) from aqueous solutions. The EKC biochar exhibited a removal efficiency of 92.5% under optimal conditions. The biochar was also subjected to surface characterization for further investigation of the varied capacity removal of the EKC biochar at low temperatures. BET analysis was performed on the EKC biochar to gather information on the surface area and pore size, and the structure of the formed pores was imaged using SEM. Furthermore, the elemental content and functional groups on the surface of the EKC biochar were determined by EDX and FT-IR analyses. The results showed that the surface and pore sizes of the EKC biochar had an interplay with the capacity removal of the EKC biochar during low-temperature carbonization. Meanwhile, it was also confirmed that the elemental ion content and the surface functional groups showed a stronger relation to the removal capacity of the EKC biochar at each low temperature applied.

Abstract

Buah vanili kering merupakan bahan pangan yang digunakan sebagai pemberi rasa dan aroma pada berbagai makanan seperti es krim, kue kering, dan sirup. Buah vanili kering dihasilkan petani melalui proses pasca panen yang panjang meliputi pemanenan, pelayuan, pemeraman dan pengeringan dengan mutu yang bervariasi. Penelitian ini bertujuan untuk mempelajari kombinasi metode pemeraman lanjut dan pengeringan untuk meningkatkan mutu buah vanili kering dan mempersingkat waktu pengeringan. Sebanyak 33 kg buah vanili dipanen, dilakukan proses pelayuan dengan cara direndam dalam air panas bersuhu 60-65°C selama 2 menit, dilanjutkan dengan proses pemeraman selama 48 jam. Setelah itu, buah vanili diberi perlakuan tiga waktu pemeraman lanjutan (4,6, dan 8 hari) dan dua metode pengeringan (pengering efek rumah kaca dan pengering tipe rak). Proses ini berlanjut hingga kadar air mencapai 30-35%. Pengukuran fisika-kimia dan uji organoleptik dilakukan untuk memantau perubahan kualitas buah vanili selama perlakuan. Hasil penelitian menunjukkan bahwa penambahan pemeraman lanjutan selama 4 hari, 6 hari, dan 8 hari pada proses pengeringan berpengaruh nyata terhadap kadar air, warna, dan kadar vanilin buah vanili kering. Buah vanila yang diberi perlakuan pemeraman lanjutan selama 8 hari dengan pengering tipe rak menghasilkan kualitas buah vanila kering terbaik dengan waktu pengeringan yang lebih singkat yaitu 8 hari, dibandingkan dengan pengeringan tradisional 20 hari dan pengering efek rumah kaca 10 hari untuk mencapai kadar air 35%.

Abstract

Rice is a major food crop in Indonesia that requires special attention in the milling process to ensure working time efficiency. This study aimed to identify the division of work elements in the rice milling process, determine the standard time used by operators, and provide recommendations for improving the work system in the Unsoed “Teaching Industry”. Data was collected by measuring the time of each work element in the rice milling process using a stopwatch. The work elements were divided into two groups: rice milling and rice packaging elements. The analysis methods included data adequacy and uniformity tests, as well as calculations of the normal time and standard time. The results of the analysis showed that the standard time for the rice milling process was 5,920.55 seconds per 100 kg of rice, while the standard time for the rice packaging process reached 27,549.81 seconds per 100 kg of rice. The time required was still relatively long compared to previous studies; therefore, several improvements were recommended, including eliminating unnecessary work elements, thoroughly maintaining the tools in the RMU, and placing a bucket in the outlet hole when changing sacks to reduce the time to collect scattered rice. In addition, the elements of rice sorting can be eliminated in the rice packaging process. Other recommendations include improving the working environment by encouraging workers to wear masks during rice milling.
