Abstract

Irrigation is the most important part of plant cultivation to meet the water needs for plant growth and yield. However, irrigation is a common problem in dryland areas. The drip irrigation system is an alternative to solve the problem of water droplets that can improve water use efficiency. One consideration when using drip irrigation is designing the irrigation layout so that the water supply to each plant is uniform. This study evaluated two layout layouts of drip irrigation systems for pok choi plants (Brassica rapa var. chinensis L.) with different planting media. The method used a split-plot design with 2 factors. Variation of drip irrigation system (V) was the main plot which consists of 2 levels, namely variation 1 (V1) and variation 2 (V2). Media type (M) served as a subplot comprised of 3 levels, namely soil (M0), soil+charcoal husk (M1), and soil+cocopeat (M2). The feasibility of these two drip irrigation system designs included drip discharge values, water uniformity coefficient, water distribution uniformity, and storage efficiency. Based on the evaluation of the feasibility of drip irrigation system design, design 1 (V1) gave better values for the average value of drip discharge (0.16 l/minute), uniformity coefficient (99.71%), uniformity of water supply (82.11%), and storage efficiency (73.89 %). The layout of the drip irrigation had a significant effect on the height of pok choi plants on 1 and 2 WAP.

Abstract

Soybean (Glycine max Merril.) is a strategic food crop whose productivity must be improved to meet increasing national demand. The use of Plant Growth Promoting Rhizobacteria (PGPR) offers a promising approach to enhance plant growth and yield. This study evaluated the effects of PGPR types and application frequencies on the growth and yield of the Grobogan soybean variety. The experiment, conducted from June to September 2025, employed a two-factor Randomized Complete Block Design with five PGPR types and three application frequencies. Results showed that PGPR type significantly affected plant height, leaf number, and pod number, while application frequency significantly influenced plant height at 10 WAP and pod number. Bamboo root PGPR produced the best performance, with a plant height of 78.84 cm, 43 leaves, and 110 pods under three applications. These findings demonstrate that bamboo root PGPR is a promising biological agent for sustainably improving soybean productivity.

Abstract

This study aimed to determine the diversity and dominance of weeds in coffee plantations in Gunung Karang, Swadaya Village, Karang Tanjung District, Pandeglang Regency. The method used was a belt transect with a plot size of 1 × 1 m at three land elevations, namely 500, 600, and 700 masl. The results showed that the diversity of weed species is quite high with a total of 20 species from 14 families. The composition and dominance of weeds varied at each elevation. At an altitude of 500 masl, the dominant weed is Oplismenus compositus (Poaceae), while at 600 masl it is dominated by Synedrella nodiflora (Asteraceae) and Peperomia pellucida (Piperaceae). At 700 masl, Spermacoce latifolia (Rubiaceae) showed the highest Importance Value Index (IVI) value, indicating a high level of adaptation and competitiveness in the highlands. Environmental factors such as light intensity, humidity, and location altitude influence the diversity and structure of the weed community. The dominance of certain weeds can inhibit the growth of coffee plants, so an effective and sustainable weed control strategy is needed, for example by means of an integrated control approach that includes manual, mechanical, and technical cultural methods, such as routine weeding and the use of competitive ground cover plants. Keywords: Coffee, Diversity, Dominance, Gunung karang, Weeds. Abstrak: Penelitian ini bertujuan untuk mengetahui keanekaragaman dan dominansi gulma pada lahan pertanaman kopi di Gunung Karang, Desa Swadaya, Kecamatan Karang Tanjung, Kabupaten Pandeglang. Metode yang digunakan adalah belt transect dengan ukuran plot 1 × 1 m pada tiga ketinggian lahan, yaitu 500, 600, dan 700 mdpl. Hasil penelitian menunjukkan bahwa keanekaragaman jenis gulma tergolong cukup tinggi dengan total 20 jenis yang berasal dari 14 famili. Komposisi dan dominansi gulma bervariasi pada setiap ketinggian. Pada ketinggian 500 mdpl, gulma yang dominan adalah Oplismenus compositus (Poaceae), sedangkan pada 600 mdpl didominasi oleh Synedrella nodiflora (Asteraceae) dan Peperomia pellucida (Piperaceae). Pada 700 mdpl, Spermacoce latifolia (Rubiaceae) menunjukkan nilai Indeks Nilai Penting (INP) tertinggi, menandakan tingkat adaptasi dan daya saing yang tinggi di dataran tinggi. Faktor lingkungan seperti intensitas cahaya, kelembapan, dan ketinggian lokasi berpengaruh terhadap keanekaragaman dan struktur komunitas gulma. Dominansi gulma tertentu dapat menghambat pertumbuhan tanaman kopi, sehingga diperlukan strategi pengendalian gulma yang efektif dan berkelanjutan, misalnya dengan cara pendekatan pengendalian terpadu yang mencakup cara manual, mekanis, dan kultur teknis, seperti penyiangan rutin serta pemanfaatan tanaman penutup tanah yang kompetitif. Kata-Kata Kunci: Dominansi, Gulma, Kopi, Gunung karang, Keanekaragaman

Abstract

Pepaya merupakan buah tropis unggulan yang sangat potensial untuk dibudidayakan. Salah satu jeni s pepaya yang termasuk komoditas unggulan yaitu pepaya varietas Calina IPB-9. Penelitian ini bertujuan untuk mengetahui pengaruh interval penyiraman irigasi tetes dan jenis media tanam terhadap pertumbuhan tanaman pepaya (Carica papaya L.) var. Calina IPB-9. Penelitian ini dilakukan di Linkungan Ciwaktu Lor, Kecamatan Serang, Kota Serang, Provinsi Banten, dari Agustus 2025 hingga Oktober 2025. Penelitian ini menggunakan rancangan acak kelompok  dengan dua faktor. Faktor pertama adalah interval penyiraman (I), yang terdiri dari 3 tingkat: satu kali sehari (I1), dua kali sehari (I2), dan tiga kali sehari (I3). Faktor kedua adalah media tanam (M), yang terdiri dari 4 tingkat: tanah (M0), tanah+cocopeat (M1), tanah+arang sekam (M2), dan tanah+serasah daun bambu (M3). Hasil penelitian menunjukkan bahwa interval penyiraman tiga kali sehari (I3) memberikan hasil terbaik terhadap parameter tinggi tanaman 69,66 cm pada umur 15 MST, dan jumlah daun 14,83 helai pada umur 15 MST. Jenis media tanam tanah+arang sekam (M2) memberikan hasil terbaik terhadap parameter jumlah daun 14,22 helai pada umur 15 MST, dan media tanam tanah + cocopeat (M1) memberikan hasil terbaik terhadap diameter batang 2,67 cm pada umur 15 MST.

Abstract

Kopi (Coffea sp.) merupakan komoditi perkebunan dengan nilai ekonomis dan tingkat ekspor tinggi bagi Indonesia. Tingkat konsumsi kopi terus bertambah. Salah satu jenis kopi yang ada di Banten yaitu kopi robusta (Coffea canephora). Serangan hama dan penyakit menyebabkan kerugian produktivitas dan kualitas. Penelitian bertujuan untuk menginventarisasi dan mengidentifikasi penyakit dan patogen yang menyerang tanaman kopi robusta pada 3 lokasi yang berbeda di kawasan Gunung Karang. Penelitian ini dilaksanakan pada bulan Oktober 2024 hingga Januari 2025. Penelitian ini merupakan penelitian deskriptif kuantitatif dengan menggunakan metode survei. Pengamatan dilakukan secara makroskopis dan mikroskopis terhadap bagian batang, daun, dan buah kopi yang terserang penyakit. Hasil penelitian menunjukkan bahwa faktor biotik dan abiotik seperti patogen, tanaman inang, suhu, kelembapan, intensitas penyinaran, dan curah hujan dapat menyebabkan tanaman kopi rentan terserang penyakit. Penyakit utama yang menyerang tanaman kopi robusta di kawasan Gunung Karang adalah kapang jelaga (Capnodium coffeicola) dengan rata-rata kejadian penyakit sebesar 88,89%, karat daun (Hemileia vastatrix) sebesar 46,67%, dan bercak daun (Cercospora coffeicola) sebesar 42,23%.

Abstract

The process of germination of soursop seeds can occur if the seed coat is permeable to water and sufficient water is available with a certain osmotic pressure. This study aims to determine the effect of jakaba on the germination of soursop seeds (Annona muricata L). This study used a factorial randomized block design (RAK) with 2 factors, namely scarification (S) as the first factor consisting of 3 levels including S1 = cutting half of the seed, S2 = cutting and S3 = peeling half of the seed coat. The second factor is the duration of soaking jakaba POC (P) which consists of 4 levels including P1 = 6 hours, P2 = 12 hours, P3 = 18 hours, and P4 = 24 hours. The results of this study are the combination of peeling half of the seed coat and soaking Jakaba POC for 6 hours (P1S3) is the best treatment that increases germination power up to 86.67%. On its own, peeling effectively stimulates germination, while cutting the seeds produces the longest shoots (10.21 cm). For soaking, a soaking time of 12–24 hours is most effective in accelerating germination time and supporting strong shoot growth
