Abstract

Kebun Inovasi is one of the teaching factories at Politeknik Negeri Jember (Polije) that produces various food and horticultural crops sustainably, including watermelon. However, observations showed a high abundance of weeds growing in the watermelon cultivation areas. Therefore, this study aimed to determine the vegetation composition and utilization potential of weeds in the watermelon cultivation areas at Kebun Inovasi Polije to support appropriate weed management planning. Sampling was conducted using a purposive sampling technique with the quadrat method. A total of ten plots (1 × 1 m) were established in areas with weed vegetation. Weed identification was carried out based on morphological characteristics and relevant literature. The results showed that 17 weed species belonging to 13 families were found, with a moderate species diversity index. Torenia crustacea was identified as the most dominant species. The identified weed species have potential uses in the fields of health, environmental management, and industry.

Abstract

Kopi merupakan komoditas unggulan di Indonesia dengan tren peningkatan luas areal perkebunan dalam beberapa tahun terakhir. Peningkatan ini diikuti oleh kebutuhan bibit kopi bermutu yang semakin besar. Selain itu, limbah kulit kopi dari sentra pengolahan kopi berpotensi dimanfaatkan sebagai pupuk kompos dan pupuk cair. Penelitian ini bertujuan mengetahui dampak pemberian kompos limbah kulit kopi dan pupuk cair kulit kopi terhadap pertumbuhan pembibitan kopi Robusta. Pelaksanaan penelitian di kebun pembibitan Laboratorium Teknologi Benih Politeknik Negeri Jember pada November 2022–Maret 2023. Penelitian menggunakan RAK factorial, terdiri dua faktor yaitu faktor pertama komposisi kompos limbah kulit kopi (M) yaitu 30% (M1), 50% (M2), dan 70% (M3); dan faktor kedua adalah konsentrasi pupuk organik cair kulit kopi (P) yaitu 100 mL/L (P1), 200  mL/L (P2), dan 300  mL/L (3) sehingga terdapat 9 kombinasi perlakuan. Parameter pengamatan meliputi tinggi tanaman, klorofil daun, jumlah daun dan volume akar. Data dianalisis menggunakan sidik ragam dan uji lanjut DMRT 5%. Hasil  penelitian menunjukkan perlakuan tunggal M3 memberikan perlakuan terbaik terhadap tinggi tanaman bulan ke 2; dan perlakuan tunggal M2 dan M1 menghasilkan nilai klorofil daun tertinggi pada bulan yang sama.  Pemberian kompos limbah kulit kopi dan pupuk cair kulit kopi tidak memberikan pengaruh nyata pada variabel pengamatan lainnya.

Abstract

This study investigated the impact of liquid organic fertilizer (POC) application on the vegetative growth of various types of mustard plants, focusing on parameters such as plant weight, plant height, and number of leaves. The results showed that the application of POC significantly enhanced these growth parameters compared to treatments without POC. Among the POCs tested, formulations derived from organic materials such as onion waste, vegetable scraps, and eggshells demonstrated their effectiveness in supporting mustard plant growth. POCs supply essential macro- and micronutrients, as well as organic compounds which are crucial for improving plant physiological processes. Specifically, onion waste POC yielded the highest plant weight, while vegetable and eggshell POC contributed significantly to plant height and the number of leaves. The findings underline the importance of POC as an alternative, eco-friendly fertilizer capable of boosting mustard plant productivity during the vegetative growth phase. These results highlight the potential for POC to replace or supplement synthetic fertilizers, offering a sustainable solution to enhance crop yields while promoting soil health. Future research could explore optimizing POC formulations and application methods for broader agricultural use. Keywords: Mustard; Liquid Organic Fertilizer; Growth

Abstract

This study aimed to determine the effect of manure and potassium fertilizer application on the growth and yield of sweet corn (Zea mays saccharata). The experiment was conducted in Ringinanom Village, Nganjuk Regency, from June to August 2025 using a Randomized Block Design (RBD) with two factors: manure dosage (0, 4, 8, and 12 kg/plot) and potassium fertilizer dosage (0, 3, 5, and 6 g/plant). The results showed that both manure and potassium fertilizers significantly affected plant growth and yield. For plant height, manure at 4–8 kg/plot resulted in the best growth up to the late vegetative stage (44 days after planting). The highest number of leaves was obtained from the combination of 12 kg/plot manure and 5 g/plant potassium fertilizer. At the generative stage, potassium at 5 g/plant produced the longest ear (20.33 cm) and the largest ear diameter (4.91 cm). These findings indicate that combining organic manure with potassium fertilizer enhances nutrient uptake efficiency, photosynthetic activity, and generative organ formation. Agronomically, the integration of organic and inorganic fertilizers effectively improves soil fertility and optimizes sweet corn productivity.
