Abstract

Cultivating red onion on a Vertisol during rainny season could face to physical and chemical problems from the soil. Application of biochar and mycorrhiza can improve soil quality both physical and chemical properties of Vertisol. The objective of this study was to investigate the effect of rice husk biochar and arbuscular mycorrhizal fungus (AMF) on growth and yield of red onion grown on a vertisol. The research was carried out at the Agrotechnology Research Station, University of Trunojoyo Madura from December 2018 to February 2019. The experiments were arranged on Split Plot Design (SPD) with the main plots were the biochar treatments and the sub plots were AMF applications. Two rates of biochar applications namely B0 (no biochar) and B1 (10 ton/ha), and four rates of AMF applications involving M0 (no mycorrhiza), M1 (2.5 g/plant), M2 (5 g/plant) and M3 (10 g/plant), were employed. No P fertilizer was applied on three AMF treatments (M1, M2, and M3). There were 8 combination treatments, and each treatment was replicated four times to end up in 32 experimental units. The results showed that there was no interaction between biochar and AMF treatments on all observed parameters. Biochar increased the number of leaves at 4 and 6 WAP (week after planting), the number of roots, and the weight of fresh tubers, and dry tubers that were suitable for storage. Mycorrhizal (AMF) application significantly influenced the number of leaves at 2 and 6 WAP, number of roots, wet weight of tubers, dry weight of tubers, and percentage of AMF root colonization. The application of rice husk biochar and AMF increased tuber yields respectively up to 17.21% and 19.58% compared to that of control.

Abstract

Abstrak Sistem pertanian dengan produksi yang maksimal dan optimal diperlukan untuk dapat diadopsi pada pertanian di Indonesia mengingat semakin meningkatnya populasi penduduk Indonesia. Salah satu teknologi pertanian untuk meningkatkan produksi adalah pemupukan otomatis dengan sistem irigasi tetes (fertigasi). Penerapan sistem fertigasi ini mengacu pada pemberian nutrisi tepat sasaran sesuai dengan kebutuhan tanaman sehingga dapat menghemat input sumberdaya. Selada memiliki potensi cukup menjanjikan untuk dikembangkan sebagai komoditas ekspor. Penelitian ini dilaksanakan untuk merancang alat fertigasi otomatis dengan sistem irigasi tetes dan kontrol lingkungan dan mengetahui pengujian alat fertigasi otomatis terhadap tanaman selada hijau (Lactuca sativa L.). Hasil penelitian diharapkan dapat diimplementasikan dan dikembangkan di masyarakat. Penelitian dilakukan mulai dari perancangan, persiapan alat dan bahan; pengujian setiap komponen alat; perakitan dan pemrograman; pengujian sistem alat; dan pengujian terhadap tanaman selada. Alat ini menggunakan komponen sensor, mikrokontroler dan aktuator serta berbasis IoT (Internet of Things). Hasil menunjukkan alat dapat bekerja dengan baik sesuai dengan ketentuan program yang diberikan dan hasil pengujian sensor alat mendapatkan nilai akurasi baik. Kinerja alat juga dapat dimonitoring melalui Smartphone Android. Hasil pengujian alat terhadap tanaman selada mendapat hasil lebih baik pada tinggi, bobot segar dan bobot ekonomis tanaman. Namun tidak menunjukkan perbedaan jauh pada jumlah daun. Abstract Indonesia needs to adopt the agricultural technique that gives high production to fulfill the need of its population. Automatic fertilizing with a drip irrigation system is one of the agricultural technologies to boost yield. Using this fertigation technology involves giving specific nutrients to plants based on their demands to conserve resource inputs. The potential for developing lettuce as an export commodity is highly encouraging. This study was to build an automatic fertigation device that includes a drip irrigation system, environmental management and to decide whether to test the device on green lettuce (Lactuca sativa L.). The research results are anticipated to be adopted and expanded in the community. The research began with designing and preparing instruments and materials; testing each instrument element; construction and programming; system testing tools; and evaluating lettuce plants. This instrument employs sensor components, microcontrollers, and actuators and is based on the IoT (Internet of Things). The results showed that the apparatus could function effectively following the program's specifications. However, the sensor could perform the tool's performance with high accuracy and be tracked by an Android smartphone. Testing the apparatus on lettuce plants showed that the plant tended to improve its height and yield in terms of fresh weight and economic weight compared to the plant watered manually. Moreover, there was less variation in the number of leaves of the plant.

Abstract

Penelitian ini bertujuan untuk mengetahui perbedaan efektivitas bahan pelapis benih jagung dari bentonit, biochar, batubara muda dan kompos biochar terhadap vigor benih pada kondisi cekaman kekeringan. Penelitian ini dilaksanakan di Laboratorium Terpadu dan rumah kaca, dari bulan September sampai Januari 2022. Penelitian menggunakan rancangan penelitian Rancangan Acak Lengkap Faktorial. Faktor pertama ialah perlakuan bahan coating dan faktor kedua ialah cekaman kekeringan. Berdasarkan penelitian dapat disimpulkan bahwa pelapisan benih dengan pengujian dikertas merang metode Ukddp tidak berpengaruh nyata pada ketiga parameter yaitu daya berkecambah, indeks vigor, dan potensi tumbuh maksimum. Namun berpengaruh nyata pada pengujian dimedia tanah. Sedangkan pada parameter panjang tunas dengan pengujian dikertas merang metode Ukddp tidak berpengaruh nyata pada parameter panjang tunas. Sama halnya dengan pengujian dimedia tanah hasil analisis ragam menunjukkan tidak berpengaruh nyata pada parameter panjang tunas. Perlu adanya pengamatan lebih lanjut sehingga dapat diketahui adanya pengaruh pada perlakuan bahan pelapis benih dan cekaman kekeringan.

Abstract

Sandy clay loam soil in Bangkalan is a soil with a low content of nutrients, organic matter, bases, and cation exchange capacity (CEC), which inhibits the growth of maize plants. In addition, the nature of the soil causes the fertilizer to become more soluble, and the absorption of nutrients, especially potassium, is low. One of the efforts to increase potassium uptake in sandy loam soils is applying biochar and acid-activated bentonite. This study aimed to examine the effect of adding biochar and acid-activated bentonite to the nutrient uptake of maize plants in the sandy soil of Bangkalan. Biochar was prepared from maize cobs by the Kon-Tiki method; bentonite was activated by physical (200 oC) and chemical (1N H2SO4) methods. The greenhouse experiment was carried out using a completely randomized design with biochar (B) and acid-activated bentonite (T) as treatments, each with three levels, namely 0, 5, 10 t ha-1 and three replications. Soil analysis performed included pH, organic carbon, CEC and exchangeable bases, while plant tissue analysis included leaf height and area. The results showed that the combination of biochar and acid-activated bentonite significantly increased soil pH, soil exchangeable K, soil exchangeable Na, and leaf area of maize plants. A single application of biochar significantly increased soil organic C and maize plant height. The application of acid-activated bentonite significantly increased the CEC of sandy loam soils.

One way to reduce carbon emissions is to prevent land cover change, especially forests for other uses in tropical areas such as forests in the Blega watershed area. This study aims to look at land cover change and its effect on surface carbon stock in the Blega watershed from 1990-2020. This research was conducted in the Blega watershed area through 6 stages, namely: 1) Geometric correction, 2) Band composite, 3) Training sample on Area of Interest (AoI), 4) Training sample test, 5) Land cover classification and 6) Carbon stock calculation. The results of image analysis of the Blega watershed area show that the average land cover in 1990, 2000, 2010, and 2020 are dry land agriculture (69%), plantation forest (11.2%), rice fields (8.77%), plantation forest (4.59%), ponds (2.65%), mixed dry land agriculture (1.56%), secondary mangrove forest (0.87%), settlements (0.70%), shrubs (0.63%) and the remaining open land. The land cover changed 1990-2000 from swamp scrub to dry land agriculture (8,819.81 ha), paddy fields (2,629.13 ha), and settlements (152.57 ha). The period 2000-2010 saw land cover change in Mixed Dryland Agriculture-Settlement of 654.14 ha. The 2010-2020 period saw the highest land conversion in paddy fields - ponds with an area of 4,571.08, scrub - paddy fields, and secondary mangrove forest - ponds with an area of 343.12 and 316.13 ha respectively, and a small portion of other land covers. Furthermore, in the 2010-2020 period, rice field land cover decreased by 4,302.7 ha. The change in land cover affects the change in carbon stock in the Blega watershed, which during the 1990-2020 period decreased by 25.98%.1990-2000 experienced a decrease of 19.41%, 2000-2010 and 2010-2020 experienced a decrease of 1.55% and 5.02% respectively. Keywords: carbon emissions, surface c stock, madura

Abstract

Part of the dry land in Madura developed from parent material, namely sand sediments which have a low organic matter content. This study aimed to determine differences in the effectiveness of corn seed coating materials from bentonite, biochar, lignite, and biochar compost on the growth and yield of maize (Zea mays L.) under drought stress conditions. This study was conducted at the Integrated Laboratory and screen house of the Faculty of Agriculture, University of Jember, using a completely randomized design. The treatments tested in this study comprised two factors. The first factor was the treatment of coating materials, namely C0 = without coating (control), C1 = bentonite coating, C2 = biochar coating, C3 = lignite coal coating, and C4 = biochar compost coating. The second factor is the level of drought stress, namely K0 = control (100% KL moisture), K1 = Light stress (80% KL moisture), K2 = moderate stress (60% KL moisture), and K3 = severe stress (40% KL moisture). The results showed that the combination of seed coating agent treatment and drought stress had a significant effect on the parameters of plant height, number of leaves, leaf area, age of male and female flowers, cob length, cob diameter without husks, biomass dry weight, and production potential per hectare. The coal coating material and light drought stress 80% KL (C3K1) was the best combination of seed coating and drought stress treatment.

Abstract

Slow-release fertilizer can provide nutrients more efficiently; nutrients are released and available slowly so that they have the potential to be absorbed by plants. This study aimed to investigate the effects of several slow-release N fertilizers on the growth and yield of corn (Zea mays L.) in sandy soil. This research was carried out in the greenhouse and laboratory of the Faculty of Agriculture, University of Trunojoyo Madura. The experiment was arranged on a non-factorial completely randomized design. There were six treatment levels, namely P0 (uncoated urea fertilizer, applied into one application), P1 (uncoated urea fertilizer, split into three times applications), P2 (urea fertilizer with bentonite coating, P3 (urea fertilizer with biochar coating), P4 (urea fertilizer with coal coating), and P5 (urea fertilizer with biochar compost coating). All coated urea fertilizers were applied one time at the early growth of corn. The results showed that the application of slow-release N fertilizer had no significant effect on plant height, number of leaves, leaf area, cob length, diameter, plant fresh weight, plant dry weight, seed weight per plant, 100 seed weight, and flower age. However, the application of slow-release N fertilizer had a very significant effect on plant height at 42 DAP, the number of leaves at 14 DAP and 56 DAP, and leaf area at 28 DAP and 56 DAP. All coated urea fertilizers were as effective as uncoated urea on the growth and yield of corn.

Abstract

Maize is one of the most important food commodities after rice and is widely cultivated because it has a high protein value. The purpose of this study was to determine the effectiveness of the coating material on the growth and yield of maize under saline stress. This research was conducted in the Agroecotechnology greenhouse of the Faculty of Agriculture, University of Trunojoyo Madura from August 2022 to January 2023. This study used a factorial Completely Randomized Design (CRD) with 10 treatment combinations and 3 replications with a factor of one coating material (P) and a factor of two salinity (K). The coating material factor consisted of 5 treatments namely control (P0), bentonite (P1), biochar (P2), light coal (P3), and biochar compost (P4), the saline stress factor consisted of 2 treatments namely control (K0) and saline (K1). The results showed that the application of coating material to saline stress had a significant effect on all growth parameters. The interaction between treatments only had a significant effect on plant height at 1 MST, leaf area at 6 MST, and 100 seed weight. Treatment (P2K1) with biochar and saline showed the best results on all growth and yield parameters of maize. Saline stress reduced the percentage of growth and yield of maize by about 50%.
