Abstract

The use of local ameliorants has the potential to be an effective solution in improving the quality of post-tin mining soil that is poor in nutrients and has a coarse texture. This study aims to analyze the effect of oil palm bunch ash, coconut shell ash, and chicken manure on the germination of two kale varieties (Nemo and Nita) in degraded media. The study used a two-factor Completely Randomized Design (CRD) at the Precision Agriculture Laboratory of the Bangka Belitung State Manufacturing Polytechnic. The parameters observed included plumule length, radicle, fresh weight of seedlings, fresh weight of roots, and dry weight of roots. The results showed that the percentage and germination capacity did not differ significantly between treatments. However, radicle length, fresh weight, and dry weight of seedlings showed a significant effect, with the best response achieved by the coconut shell ash and oil palm bunch ash treatments. Local ameliorants also caused positive changes in soil physical properties, especially in the color and texture of the media. In conclusion, local ameliorants proved effective in improving the initial conditions of post-mining soil and successfully supported kale germination.

Abstract

Rice is a very important and strategic commodity because it is the main source of carbohydrates for the community. Therefore, an increase in rice production is urgently needed. Swampland is considered a potential option to support food self-sufficiency, given the various advantages it has. One of the main advantages is the availability of abundant water, which is crucial in supporting plant growth, especially in uncertain climatic conditions. Fertilizer is one of the key factors in rice farming. Nitrogen (N) is one of the most important nutrients and should be available to plants. Foliar nutrition can generally increase grain yield while reducing the amount of fertilizer administered through soil application. The purpose of this study is to obtain the concentration and intensity of foliar urea application that is most effective in supporting the growth and yield of rice cultivated in swampland. The experiment was carried out using a complete group random design (RAKL) with a factorial design involving 2 factors and 3 replicates. The first factor is the concentration of urea solution, which consists of 4 levels, namely 3%, 6%, 9%, and 12%. The second factor is the intensity of the application which consists of 3 levels, namely 2 mst, 2 mst, and 4 mst, as well as 2 mst, 4 mst, and 6 mst.

Abstract

Lahan kering umumnya memiliki pH masam, kandungan bahan organik rendah, serta ketersediaan unsur hara yang terbatas, sehingga produktivitasnya belum optimal. Penelitian ini bertujuan menganalisis pengaruh pemberian hidrogel berbahan limbah daun nanas yang diperkaya Pseudomonas fluorescens terhadap perubahan sifat kimia tanah di lahan kering. Penelitian dilakukan menggunakan rancangan acak lengkap dengan tiga perlakuan, yaitu tanpa hidrogel (kontrol), hidrogel + P. fluorescens, dan hidrogel tanpa bakteri, masing-masing diulang empat kali. Parameter yang diamati meliputi pH tanah, C-organik, N-total, P₂O₅ tersedia, kation basa (K, Ca, Mg, Na), kapasitas tukar kation (KTK), kejenuhan basa, serta Al³⁺ dan H⁺ yang dapat ditukar. Hasil penelitian menunjukkan bahwa perlakuan hidrogel + P. fluorescens memberikan perbaikan paling signifikan dibandingkan perlakuan lainnya, ditandai dengan peningkatan pH dari 5,85 menjadi 6,15, C-organik dari 2,45% menjadi 4,06%, N-total dari 0,13% menjadi 0,33%, dan P₂O₅ dari 10,86 ppm menjadi 17,60 ppm. Selain itu, terjadi peningkatan KTK dan kejenuhan basa serta penurunan Al³⁺ dan H⁺ yang dapat ditukar. Temuan ini menunjukkan adanya sinergi antara fungsi hidrogel sebagai sumber bahan organik dan peran bakteri dalam meningkatkan ketersediaan hara serta menekan kemasaman tanah. Dengan demikian, kombinasi hidrogel limbah daun nanas dan P. fluorescens berpotensi menjadi strategi bioameliorasi yang ramah lingkungan untuk rehabilitasi lahan kering.

Abstract

Kiambang is an aquatic weed commonly found in Indonesian waters. Kiambang extract contains secondary metabolite compounds that have the potential to inhibit the growth of billygoat weed (Ageratum conyzoides), which is commonly found in agricultural and plantation areas. This study was conducted to determine the potential of kiambang extract as a bioherbicide against billygoat weed. The study employed a Completely Randomized Design (CRD) consisting of five concentrations of kiambang extract, namely 0%, 20%, 40%, 60%, and 80%, with four replications. The observed parameters included weed mortality percentage, weed height, and bioherbicide efficacy. A significant effect on bioherbicide efficacy was first observed at a concentration of 40%, resulting in an efficacy value of 7.18%, while the highest efficacy was achieved at 60% concentration (42.46%). Meanwhile, significant effects on weed mortality percentage and weed height were observed starting at a concentration of 60%. Kiambang extract can be utilized as a contact bioherbicide for controlling billygoat weed, commonly found in agricultural and plantation areas.

Abstract

Selada (Lactuca sativa) merupakan tanaman hortikultura yang dikonsumsi secara global, baik di iklim sub-tropis maupun tropis dan menjadi salah satu jenis tanaman sayuran yang bernilai ekonomi tinggi. Idealnya semua benih harus memiliki kekuatan tumbuh yang tinggi, sehingga bila ditanam pada kondisi lapangan yang beraneka ragam akan tetap tumbuh sehat dan kuat serta berproduksi tinggi dengan kualitas baik. Kemunduran suatu benih dapat diterangkan sebagai turunnya kualitas atau viabilitas benih yang mengakibatkan rendahnya vigor dan jeleknya pertumbuhan tanaman serta produksi. Salah satu cara untuk mempercepat perkecambahan benih adalah pemberian zat pengatur tumbuh (ZPT). Bahan alami yang dapat digunakan sebagai substitusi ZPT diantaranya adalah air kelapa. Penelitian ini telah dilaksanakan di Laboratorium Pertanian Presisi, Politeknik Manufaktur Negeri Bangka Belitung pada bulan Februari sampai dengan bulan Maret 2025, menggunakan Rancangan Acak Lengkap (RAL) satu faktor dengan 4 perlakuan yaitu : Akuades, Air kelapa 50%, Air kelapa 75% dan Air kelapa 100%. Variabel pengamatan yang dilakukan adalah sebagai berikut : persentase perkecambahan, indeks kecepatan perkecambahan, waktu rata-rata perkecambahan, panjang plumula, panjang radikula, berat basah dan berat kering. Berdasarkan hasil penelitian dapat disimpulkan bahwa perendaman air kelapa berpengaruh terhadap perkecambahan benih selada. Pengaplikasian terbaik diperoleh pada konsentrasi 50%.

Abstract

The increase in the use of electric bicycles has led to the need for an efficient and safe charging system. This study designed a prototype of a smart charging system for electric bicycles based on the Internet of Things (IoT) to facilitate real-time and remote monitoring of charging. This system uses an ESP32 microcontroller, a 24V 15A power supply, 400W and 1200W step-up converters, and ACS712 30A voltage and current sensors. Charging data is displayed through the Blynk application to facilitate user monitoring. Test results show that the voltage increases until it stabilizes, while the current decreases over time during charging, indicating that the system works safely and efficiently (voltage 45–57 V, current approximately 2 A to nearly 0 A, time 0 to 353 minutes). Electricity consumption increases at the start of charging and then decreases, while charging costs continue to accumulate, indicating that the system is capable of calculating energy and estimating costs in real-time (maximum energy approximately 0.0018 kWh, cost approximately Rp1,200–Rp1,300).

Abstract

Lahan rawa memiliki potensi besar untuk pengembangan padi, namun efisiensi pemupukan nitrogen pada kondisi tersebut relatif rendah akibat berbagai proses kehilangan hara. Penelitian ini bertujuan untuk mengevaluasi pengaruh dosis dan interval aplikasi larutan urea melalui daun terhadap dinamika serapan nitrogen pada tanaman padi. Penelitian dilaksanakan di Kebun Percobaan Sosio-Ekonomi Pertanian Universitas PGRI Silampari, dan analisis N dilakukan di Laboratorium Ilmu Tanah Unib. Percobaan menggunakan rancangan faktorial dalam (RAKL) dengan dua faktor dan tiga ulangan. Faktor pertama adalah dosis larutan urea (3%, 6%, 9%, dan 12%), sedangkan faktor kedua adalah interval aplikasi (1, 2, dan 3 kali). Perlakuan kontrol aplikasi urea 200 kg/ha yang ditebar di lahan rawa. Data dianalisis menggunakan uji F dan dilanjutkan dengan DMRT 5%. Hasil penelitian menunjukkan bahwa peningkatan dosis dan interval aplikasi urea secara foliar berpengaruh nyata terhadap serapan nitrogen pada akar, batang, dan gabah. Dosis 12% menghasilkan serapan N tertinggi, yaitu 169,53 mg/tanaman pada akar, 417,22 mg/tanaman pada batang, dan 430,01 mg/tanaman pada gabah. Sementara itu, interval aplikasi 3 kali memberikan serapan N tertinggi, yaitu 150,56 mg/tanaman pada akar, 400,41 mg/tanaman pada batang, dan 516,94 mg/tanaman pada gabah. Aplikasi urea melalui daun terbukti lebih efektif dibandingkan aplikasi melalui tanah, yang menunjukkan serapan nitrogen terendah pada seluruh parameter.

Abstract

Rusip fermentation is a traditional fish fermentation process whose quality is influenced by temperature, humidity, light intensity, and gas concentration. Conventional manual monitoring makes the fermentation process less effective. This study aims to develop an Internet of Things (IoT)-based monitoring and control system for rusip fermentation using an ESP32 microcontroller. The system integrates a DHT11 sensor for measuring temperature and humidity, an MQ-135 sensor for gas detection, a GY-30 (BH1750) sensor for measuring light intensity, and an I2C LCD, Telegram, and Blynk for real-time monitoring. Sensor performance was evaluated by comparing the DHT11 with a UT333 Mini Temperature Humidity Meter and the GY-30 with a Benetech GM1030C Lux Meter. The results showed measurement differences of 0.2°C for temperature, 3% RH for humidity, and 0.9 Lux for light intensity. One-week monitoring showed temperatures ranging from 28.70°C to 30.06°C, humidity from 83.40% to 87.70% RH, light intensity from 3.33 to 51.67 Lux, and gas concentration from 1,038 to 1,487 ppm. The proposed system successfully performed real-time monitoring and control, enabling users to remotely monitor the rusip fermentation process.

Abstract

This study aims to determine the effect of coffee grounds compost on the growth of water spinach (Ipomoea reptans), evaluated through plant height, leaf number, fresh weight, dry weight, and changes in soil and compost pH. Four treatments were applied: no fertilizer (K0), NPK fertilizer (K1), 100% coffee grounds compost (K2), and a combination of coffee grounds compost + NPK (K3). The results showed that coffee grounds compost significantly affected plant height in the third and fourth weeks but did not significantly affect leaf number. Treatment K2 produced the highest plant height, fresh weight, and dry weight, indicating the effectiveness of coffee grounds compost in supplying nutrients. Soil pH increased from acidic to near neutral after four weeks of compost application, while compost pH rose during decomposition, indicating compost maturity. Chemical analysis revealed NPK contents of 1.20% nitrogen, 0.13% phosphorus, and 0.38% potassium. Overall, coffee grounds compost demonstrates strong potential as an environmentally friendly organic fertilizer capable of improving plant growth and soil quality.
