Abstract

Weeds are one of the causes of the decline in potato production in the central plains. This research aimed to assess the diversity of weeds that appear on granola-variety potato plants (Solanum tuberosum L.) This research uses a quantitative approach by arranging frames measuring 50x50 cm in five locations spread diagonally. Weed samples were taken at 20 and 40 days after planting, and then the weed vegetation was analyzed using the index formula and weed dominance. The research found nine types of weeds, namely: Cyperus rotundus, Ageratum conyzoides L., Common purslane, Eleusine indica L. Gaertn, Commelia benghalensis, Panicum repens L., Amaranthus spinosus L., Gynura procumbens, and Bidens pilosa L. Analysis result the variety shows the level of weed diversity at 20 days after planting in the P0 treatment wich gives the best result with the lowest average value. Meanwhile, in weed diversity parameters at 60 days after planting, the highest average value was achieved by treatment P1, while the lowest average value was seen in treatment P3.

Abstract

Petani kentang di Indonesia menghadapi kendala dalam mendapatkan bibit kentang berkualitas tinggi. Salah satu proses yang bisa mendapatkan bibit kentang yang berkualitas tinggi yaitu dengan cara aklimatisasi kentang yang baik dan benar. Tujuan dari penelitian ini adalah untuk mengetahui interaksi antara media tanam dan pupuk organik cair urine kelinci terhadap pertumbuhan dan hasil setek kentang pada fase aklimatisasi untuk bibit G0. Penelitian ini dilaksanakan di Screenhouse yang berada di Pasirtalang, Desa Sirnajaya, Kecamatan Cisurupan, Kabupaten Garut, Jawa Barat.Penelitian ini dilakukan dengan menggunakan Rancangan Petak Terbagi (RPT) dengan petak utama (Main Plot) yaitu media tanam dengan lima taraf perlakuan yaitu: m1: 100% Humus Bambu m2 : 100% Cocopeat m3 : 50% Humus Bambu 50% Cocopeat m4 : 70% Humus Bambu 30% Cocopeat m5 : 70% Cocopeat 30% Humus Bambu Anak Petak (Sub Plot) yaitu POC Urine Kelinci dengan empat taraf perlakuan yaitu : k0 : 0 ml (kontrol) k1 : 2 ml/liter k2 : 4 ml/liter k3 : 6 ml/liter. Hasil penelitian menunjukkan bahwa tidak terjadi interaksi namun secara mandiri komposisi media tanam dan pupuk organik cair Urine kelinci memberikan pengaruh nyata terhadap pertumbuhan dan hasil setek kentang (Solanum tuberosum L.) pada fase aklimatisasi G0. Perlakuan 100% humus bambu dan k3 (6 ml/liter) memberikan pengaruh terbaik terhadap pertumbuhan dan hasil kentang G0.

Abstract

Okra (Abelmoschus esculentus) merupakan salah satu tanaman yang memiliki peluang bisnis untuk dibudidayakan. Limbah cair tahu merupakan sisa dari produksi tahu yang dapat mencemari lingkungan, namun dapat dimanfaatkan menjadi POC yang bermanfaat untuk okra. PGPR merupakan sekolompok bakteri yang bermanfaat bagi tanaman, PGPR dapat dimanfaatkan untuk okra dengan cara perendaman benih okra. Tujuan dari penelitian ini untuk mengetahui interaksi pemberian antara konsentrasi POC limbah tahu dan lama perendaman PGPR terhadap pertumbuhan dan hasil okra. Penelitian ini dilaksanakan di Desa Cikarag Kecamatan Malangbong Kabupaten Garut pada bulan Juni sampai Agustus 2023. Metode yang digunakan dalam peneltian ini adalah Rancangan Acak Kelompok (RAK) 2 faktor. Faktor pertama adalah POC limbah tahu (T) yang terdiri dari t0 = control, t1 = 700 ml/liter, t2 = 800 ml/liter, t3 = 900 ml/liter. Faktor kedua lama perendaman PGPR (P) yang terdiri dari p0 = kontrol, p1 = 5 jam, p2 = 6 jam, p3 = 7 jam. Hasil percobaan menunjukkan terjadi interaksi pemberian POC limbah tahu dan lama perendaman PGPR terhadap tinggi tanaman 49 HST, jumlah daun 49 HST, total buah/tanaman panen ke-2 dan total produksi buah/Plot panen ke-2. Interaksi terbaik terdapat pada taraf t3p3, dengan konsentrasi PGPR 900 ml/liter dan lama perendaman 7 jam. Pemberian konsentrasi POC limbah tahu terbaik yaitu pada taraf t3 dan perendaman dengan larutan PGPR terbaik pada taraf p3 yang memberikan rata-rata paling tinggi pada semua pengamatan. Kata kunci: limbah cair tahu, okra, perendaman, PGPR, pupuk organik cair

Abstract

Chitosan recently has been used in plant growth enhancement, as a growth promoter by increasing nutrient uptake, chlorophyll content, and photosynthesis rate. Tissue culture is the propagation of plants vegetatively in a short time and quickly. The results of the effect of chitosan application on potato planlets need to be reviewed. This study focuses on the effects of chitosan on potato plantlets and aims to determine the optimal concentration for their growth. This study used the experimental method of complete randomized design (CRD) with analysis using the Duncan Multiple Range Test (DMRT) method at a 5% level. There are 5 treatments namely, 0 mg/l, 5 mg/l, 10 mg/l, 15 mg/l and 20 mg/l and repeated 4 times. The results showed that chitosan significantly influenced the growth of potato plantlets. The best treatment was observed at a concentration of 20 mg/l, resulting in an average shoot emergence time was 5.25 days, a plantlet height was 8 cm, the number was leaves with 14 leaves, the number was roots 8.25 roots, and a root length of 8.5 cm.

Abstract

ZmES4 is a plant-derived antimicrobial peptide (AMP) from maize that shows promise as a biocontrol agent against plant pathogenic organisms. In the context of growing challenges in sustainable agriculture, AMPs like ZmES4 represent innovative alternatives to chemical pesticides. This study focuses on the structural characterization and heterologous expression of the ZmES4 peptide in Escherichia coli (E. coli). The gene encoding ZmES4 was obtained from the maize female gametophyte (NCBI Reference Sequence: NM_001112150.3) and cloned into the pET24d(+) expression vector using NcoI and XhoI restriction sites. Transformation into E. coli BL21 (DE3) cells enabled recombinant expression upon induction with isopropyl β-D-1-thiogalactopyranoside (IPTG). Sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) and Bradford assays confirmed the expression of ORF-ZmES4, with protein concentrations ranging from 14.647 to 63.606 mg/mL. The successful expression of ZmES4 in E. coli highlights its potential application as a recombinant AMP for future plant disease management strategies.

Abstract

Potato (Solanum tuberosum L.) is one of the important horticultural commodities in Indonesia. Potato cultivation is usually carried out in highland areas however, continuous planting in these regions can cause environmental damage, such as land degradation. One solution is to reduce highland cultivation and explore alternative planting methods in mid-altitude areas using different planting media compositions to optimize growth. This study was conducted in Kp. Cikarokrok, Banyuresmi District, Garut Regency, West Java, from May to August 2024. The experimental site is located at an altitude of approximately 701 meters above sea level. The experiment employed an experimental method using a Split Plot Design with two factors: variety (main plot) consisting of v₁ = Medians variety and v₂ = AR 08 variety, and planting media composition (sub-plot) consisting of m₁ = 1:1:1:1, m₂ = 2:1:1:1, m₃ = 3:1:1:1, and m₄ = 4:1:1:1. The results showed no interaction between planting media composition and potato variety in terms of growth and yield. However, the independent effect of media composition m₁ (1:1:1:1) was significant on plant height, dry plant weight, the number of tubers per plant, and tuber weight per plant. Meanwhile, treatment m₂ (2:1:1:1) significantly affected plant height and the number of tubers per plant, while treatment m₃ (3:1:1:1) influenced plant height. The Medians variety exhibited better leaf area and dry plant weight compared to the AR 08 variety.
