Abstract

Usaha tani semangka memberikan keuntungan bagi petani karena umurnya pendek, hasilnya tinggi, dan pemasarannya mudah. Pada awal abad ke-19 telah diketahui bahwa polinasi tanpa fertilisasi dapat merangsang pembentukan buah. Partenokarpi dapat terjadi secara alami (genetik) maupun buatan (induksi). Partenokarpi dapat terjadi secara alami pada beberapa jenis tanaman saja (terbatas), misalnya pada pisang triploid. Penelitian ini telah dilaksanakan pada bulan Desember 2014 – Maret 2015 di Lahan Praktikum Fakultas Pertanian, Universitas Islam Indragiri. Rancangan penelitian yang digunakan adalah Rancangan Acak Kelompok (RAK) dengan 5 perlakuan dan 5 ulangan, yaitu Kontrol ( 0 ppm), 0,015 % ( 150 ppm), 0,15 % ( 1.500 ppm ), 1,5 % ( 15.000 ppm ) dan 15 % ( 150.000 ppm). Berdasarkan dari hasil penelitian yang telah dilakukan, dapat diambil kesimpulan bahwa dosis ekstrak bawang merah terbaik untuk membentuk buah partenokarpi dari penelitian ini adalah 1.500 ppm dan tidak berbeda nyata dengan 15.000 ppm, namun berbeda nyata dengan tanaman tanpa perlakuan (kontrol), 150 ppm dan 150.000 ppm

Abstract

Background: Celery (Apium graveolens) is a horticultural crop with significant economic and culinary value, particularly in Indonesia, where leaf celery is more commonly cultivated. Despite growing interest in hydroponic farming in regions such as Bangka Belitung, celery cultivation remains limited due to challenges in seed germination, especially under lowland and hot climate conditions. Celery seeds are known for slow and inconsistent germination due to hard seed coats and naturally occurring germination inhibitors like coumarin. Seed soaking in plant growth regulators (PGRs), including natural alternatives such as red onion (Allium cepa L) extract—rich in gibberellins and auxins—has been proposed to enhance germination and seedling vigor.Aims & Methods: This study aimed to investigate the effects of different soaking durations (24 and 48 hours) and concentrations (0%, 10%, 20%, and 30%) of red onion extract on the germination performance of celery seeds.Result: The results of this study indicate that a 24-hour soaking duration is the most effective in enhancing celery seed germination as under these conditions, the seeds experience only brief exposure to low oxygen levels. However, soaking seeds in red onion extract at concentrations of 10% to 30% resulted in lower germination parameters compared to the 0% because the concentration is suspected to be too high for celery seeds. Analysis of the interaction between soaking duration and extract concentration revealed that control seeds (without soaking or directly sowing) achieved germination performance comparable to the best treatment combination in terms of germination power, germination speed index, and mean germination time. At the same time, the highest vigor index and seedling length were observed in seeds treated with 10% red onion extract for 24 hours, which also showed similar performance to the control treatment.

Abstract

Background: Soybean is one of the most popular agricultural commodities in Indonesia, but its production is still low. Thus, it is necessary to make efforts to expand its agriculture in the form of marginal land development.Aims: This study aims to examine the effect and obtain the best treatment dose of arbuscular mycorrhizal fungi (AMF) in ultisol soil to increase the growth of soybean plants (Glycine max (L.) Merill).Methods: This experimental study employed a complete randomized design (CRD) with the treatment of arbuscular mycorrhizal fungi (AMF). The AMF treatment comprised five levels: no AMF, 4 g/polibag, 8 g/polibag, 12 g/polibag and 16 g/polibag. Each treatment was repeated four times, resulting in 20 experimental units and each experimental unit comprised three polybags so that this study used 60 polybags. The data were analyzed using Analysis of Variance (ANOVA) and continued with Duncan's New Multiple Range Test (DNMRT) at the 5% level.Result: AMF treatment is able to increase the growth of soybean plants in the parameters of plant height, number of productive branches, flowering age, number of flowers, and harvest age. The AMF treatment dose of 12 g/polybag is proven to give the best results in increasing the growth of soybean plants. The use of AMF can be an effective strategy in optimizing soybean production, especially on marginal lands.

Abstract

Hidroponik adalah teknik menanam yang menggunakan air sebagai media utama tanpa melibatkan tanah, dengan fokus pada pemenuhan kebutuhan nutrisi tanaman. Metode ini memungkinkan kondisi lingkungan tumbuh yang lebih terkendali. Larutan nutrisi merupakan cairan yang mengandung unsur-unsur penting yang diperlukan tanaman untuk tumbuh dan berkembang. Pakcoy merupakan salah satu jenis sayuran daun yang populer dan sering dibudidayakan menggunakan metode hidroponik. Tujuan penelitian ini adalah untuk mengetahui respon tanaman pakcoy (Brassica rapa chinensis) terhadap nutrisi dan konsentrasi larutan nutrisi pada system hidroponik. Penelitian ini disusun dengan menggunakan Rancangan Acak Lengkap (RAL). Pelakuan yang diberikan adalah konsentrasi AB mix dan konsentrasi nutrisi formulasi mandiri dengan 3 taraf. Masing-masing perlakuan diulang sebanyak 5 kali. Pengamatan tanaman dianalisis menggunakan Anova (Analysis of variances) pada taraf 5% dan dilanjutkan dengan uji beda nyata terkecil (DMRT). Konsentrasi AB mix 1000 ppm memberikan pengaruh yang nyata pada tinggi tanaman pada pengamatan (7 hst, 14 hst dan 21 hst), jumlah daun pada pengamatan (14 hst dan 21 hst) dan bobot basah tanaman.

Abstract

Celedry (Apium graveolens L.) is one type of vegetable that has many benefits, both used for daily needs and used as medicine or vitamins to determine the optimal concentration of red onion extract and soaking duration for the germination of celery plants. This study was conducted at the Agricultural Laboratory of the State Manufacturing Polytechnic of Bangka Belitung from January to February 2025. The experimental design used was a Completely Randomized Design (RAL) with 2 factors. The first factor is concentration, with four levels namely the concentration of red onion extract 0%, 10% (K2), 20% (K3), 30% (K4). The second factor is the duration of soaking for 24 hours (W1) and 48 hours (W2). The observed variables are total wet weight of sprouts (g), total dry weight of sprouts (g), length of sprout shoot (cm), and length of sprout root (cm). The data from the research were analyzed using ANOVA variance and further tested using the DMRT test at a 5%. The research results indicate that the treatment with different concentrations of red onion extract and the duration of soaking significantly affects the total wet weight of the sprouts, the total dry weight of the sprouts, and the length of the sprout apex, but does not significantly affect the length of the root apex of celery plants. The interaction between 10% onion extract concentration and 24 hour soaking effectively increases total root weight, dry weight, and seedling shoot length of celery.

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

As the number of vehicles in Indonesia increases, the need for battery monitoring systems becomes more crucial. This study develops a battery performance monitoring system for motorcycles integrated with a mobile application based on Mit app inventor. The system utilizes an ESP32 microcontroller along with voltage, current (INA219), and temperature (DS18B20) sensors to read battery parameters in real-time. The State of Charge (SoC) is calculated using a modified coulomb counting algorithm. An active protection feature using a relay is included to prevent overcharging, overcurrent, and short circuits. Test results show that under normal conditions, battery voltage ranges from 10.5V to 12.37V with an average load current of 233.4 mA. During a 30-minute charging process, the SoC increased by 10% with an average charging voltage of 14.97V. Data is displayed in real-time via an LCD and the mobile application, enabling users to efficiently monitor battery status and take preventive actions. This system enhances the reliability and safety of battery usage in motorcycles.
