Abstract

Tanaman tomat merupakan komoditas sayuran yang memiliki nilai ekonomi tinggi. Penelitian bertujuan mengetahui konsentrasi optimum, interval aplikasi Bacillus subtilis yang tepat, dan interaksi antara konsentrasi dan interval aplikasi Bacillus subtilis sebagai pengendali penyakit layu pada tanaman tomat, telah dilakukan di Desa Panjunan, Kecamatan Petarukan Kabupaten Pemalang pada bulan Januari sampai Maret 2023. Rancangan percobaan yang digunakan split plot. Faktor pertama adalah konsentrasi Bacillus subtilis sebagai main plot yang terdiri dari 4 taraf yaitu 0 ml/l, 5 ml/l, 10 ml/l, dan 15 ml/l, faktor kedua adalah interval aplikasi Bacillus subtilis sebagai sub plot yang terdiri dari 3 taraf yaitu 1, 2, dan 3 minggu sekali, percobaan dilakukan 3 ulangan. Data dianalisis dengan Uji F apabila terdapat beda nyata, maka dilakukan uji lanjut dengan uji BNT 5%. Variabel yang diamati tinggi tanaman, jumlah daun, jumlah bunga, jumlah buah pertanaman, bobot buah pertanaman, bobot perbuah, bobot basah tanaman, bobot segar akar, panjang akar terpanjang, dan intensitas serangan penyakit. Hasil penelitian menunjukkan bahwa konsentrasi Bacillus subtilis berbeda nyata pada variabel jumlah daun, sedangkan pada variabel lain berbeda tidak nyata. Hasil terbaik pada konsentrasi 15 ml/l air. Interval aplikasi Bacillus subtilis berbeda tidak nyata pada semua variabel. Tidak terjadi interaksi antara konsentrasi dan interval aplikasi Bacillus subtilis pada semua variabel. Kata kunci: Tanaman Tomat, Konsentrasi Bacillussubtilis, Interval Bacillus subtilis

Abstract

This community service activity aims to increase students' knowledge and interest in hydroponic cultivation as a solution to overcome land limitations. The community service activity was carried out at Diponegoro Vocational School. The implementation method consists of four stages: investigation, preparation, action, and reflection with educational materials, practice, and evaluation through pre-tests and post-tests. The results of the activity showed a significant increase in aspects of basic hydroponic knowledge, types of hydroponic systems, and hydroponic market opportunities, as indicated by changes in the percentage of students who understood the material before and after the activity. In addition, the level of student interest in hydroponic cultivation increased from 35.5% to 100% after participating in educational and practical activities. These findings prove that a practice-based learning approach can strengthen modern agricultural literacy and foster entrepreneurial motivation.

Abstract

This investigation evaluated spatial and temporal variations in plankton abundance and community structure to determine their effectiveness as bioindicators of water quality in coastal rice-field ecosystems of Batang Regency, Central Java. Plankton samples were collected from five sampling stations using 80 mL film vials and subsequently identified through laboratory-based taxonomic analysis. Key physicochemical factors were measured ex situ, and the analyses evaluated plankton abundance, Shannon–Wiener diversity index (H’), evenness (e), dominance (C), and saprobic index. Results demonstrated relatively low plankton abundance, with Bacillariophyceae (40%), particularly Chaetoceros sp., representing the principal taxonomic group, followed by Chlorella sp. Moderate diversity levels (H’ = 1.45–2.85), high evenness (e > 0.6), and low dominance (C < 0.5) indicated a community structure with stable ecological dynamics. Most water quality parameters conformed to Indonesian water-quality criteria, characterized by a salinity of 0.5 g/L, temperatures of 23–24 °C, and dissolved-oxygen concentrations above 4.0 mg/L. However, the saprobic index revealed light to moderate pollution at stations near settlements and downstream river segments, likely influenced by domestic wastewater, agricultural runoff, and seawater intrusion. Overall, the ecosystem remained supportive of primary productivity, emphasizing the significance of plankton as sensitive indicators for monitoring coastal agricultural environments
