Abstract

ABSTRACTThis research examines the fertility status of irrigated rice fields in Debowae Village, Waelata District, Buru Regency, using a survey method for field work, taking composite soil samples diagonally in rice fields based on the history of fertilizer use and production data through interviews. The results of the research show that the fertility status of paddy fields in Debowae village based on chemical characteristics is low status with limiting factors including acid soil pH (5.29-5.51) to slightly acidic (5.80-5.89), low CEC (5.28-8.21me/ 100gram), C-organic low (0.53%) to low (1.17-1.67%) and N- low (0.18-0.20%) to moderate (0.21-0.24%). This had an effect on decreasing GKG production at the research location, namely 2.5-4.5 tons/ha, which means it is still relatively low when compared to national GKG production, namely 5.4 tons/ha. Therefore, the direction for balanced fertilizer management is based on the soil fertility status of the paddy fields at the research location, namely adding lime to increase soil pH, using organic material to increase soil C-organic and soil CEC, as well as using compound fertilizer using a combination of urea, NPK fertilizers. Ponska in supporting sustainable agricultural land. Key words: Soil fertility status, rice production, balanced fertilization.

Abstract

Eggplant (Solanum melongena L.) is a type of tropical plant which is included in the vegetable horticulture group where it is widely cultivated on land and in the yard. The high nutritional content of eggplant makes one of the reasons this commodity is in great demand by the public. So to get optimal results it is necessary to have a nutrient that must be met in the growth process. The presence of sufficient nutrients in the soil is one of the important factors in supporting plants to complete their life cycle, such as growing and producing optimally. Therefore, fertilization is an important activity in order to increase the presence of nutrients to avoid nutrient deficiencies that can have a negative impact on the resulting production, one of which is a decrease in production quality. Based on data from research results, nitrogen nutrients play a very important role in growth, and at the same time is a limiting element for eggplant growth, this is evidenced by the low growth indicators obtained in treatments that are not given nitrogen elements such as leaf growth, chlorophyll and dry weight produced.

Abstract

Potato (Solanum tuberosum L.) is a horticultural crop used as an alternative source of carbohydrates. The potato demand in Indonesia tends to increase yearly, but this does not align with its production. One of the efforts to increase potato production is fertilization. However, the intensive application of chemical fertilizers with increasing doses can damage the quality of the soil, kill microorganisms in the soil, and deteriorate the health of farmers. Therefore, it is necessary to conduct research to find alternative chemical fertilizers with the application of Plant Growth Promoting Rhizobacteria (PGPR) biological fertilizers. The study aimed to examine the application of PGPR to potato plants' growth, yield, and IAA levels. The sample has been taken in Kaponan Village, Pakis District, Magelang Regency. The field experiment method was a completely randomized design with four treatments and four replications. The treatments consisted of no application of PGPR, PGPR 40 mL 10 L-1 of water, PGPR 50 mL 10 L-1 of water, and PGPR of 60 mL 10 L-1 of water. The data were analyzed using the ANOVA test, and if there was a significant difference, the Duncan Multiple Range Test was continued at the 5% test level. The results showed a significantly different effect of PGPR application on growth and yields. The application of PGPR showed that the increase in IAA levels of potato plants was higher than without PGPR application. The best growth was obtained by treatment with PGPR application of 50 mL 10 L-1 of water. The PGPR application treatment of 60 mL 10 L-1 of water resulted in the best yields and the highest increase in IAA levels.

Abstract

The miana plant is an ornamental plant that has potential as a medicinal ingredient. The part of the miana plant that is used as an ornamental or medicinal plant is the leaves. Efforts to increase the growth and yield of miana plants include fertilization. This research aims to analyze the effect of different organic fertilizers on the growth and yield of miana through the application of automated drip irrigation technology. The design used in this research was a single-factor Randomized Complete Group Design, namely organic fertilizer with five levels and five replications each. The treatment levels in this study were without fertilizer (P0), cow manure (P1), goat manure (P2), chicken manure (P3), guano fertilizer (P4), and quail manure (P5). The results of the research show that differences in organic fertilizer affect miana growth through the application of automated drip irrigation technology which can be seen in the parameters of plant height, number of leaves, and number of branches. Cow manure gave the highest average value and was able to increase miana growth most dominantly at the start to the end of the observation week compared to other treatments. Meanwhile, the parameters include leaf area, stem dry weight, leaf dry weight, total biomass, and total flavonoids. Goat manure gave the highest average value and increased miana yield in the leaf area, stem dry weight, and total biomass parameters, while cow manure gave the highest average value and increased miana yield in the leaf dry weight parameter. Apart from that, quail manure gave the highest average value and increased the yield of miana on the total flavonoid parameter.

Abstract

Tanaman stevia (Stevia rebaudiana B.) merupakan tanaman obat yang memiliki daun manis dan dapat digunakan sebagai pemanis alami. Stevia dapat menjadi alternatif pengganti gula tebu yang memiliki manfaat sebagai obat diabetes, hipertensi dan obesitas. Stevia telah banyak dibudidayakan dan digunakan di banyak negara seperti Malaysia, Korea, China dan Singapura. Penelitian dilakukan pada bulan April sampai dengan Juli 2024 di perkebunan Gunadarma University Technopark (UG-TechnoPark). Penelitian ini dilakukan dengan metode Rancangan Acak Kelompok Lengkap (RAL) faktorial yang terdiri dari 2 faktor (3 × 3) yaitu faktor I (umur panen) yang terdiri dari 3 taraf yaitu 80 HSS (R1), 100 HSS (R2), dan 120 HSS (R3). Faktor II (tinggi pemangkasan) yang terdiri dari 3 taraf yaitu 5 cm (P1), 10 cm (P2), 15 cm (P3). Setiap perlakuan diulang sebanyak 4 kali ulangan sehingga terdapat 36 satuan percobaan. Hasil penelitian menunjukkan bahwa umur panen dan tinggi pemangkasan stevia tidak berpengaruh nyata terhadap pertumbuhan dengan parameter luas daun. Umur panen berpengaruh nyata terhadap hasil biomassa dengan parameter bobot tajuk, panjang tajuk, bobot basah daun, dan bobot kering daun yang menunjukkan bahwa semakin panjang (120 HSS) stevia dipanen terlebih dahulu maka hasil biomassa yang dihasilkan semakin banyak. Tinggi pemangkasan berpengaruh nyata terhadap persentase tanaman yang hidup setelah panen dan jumlah daun yang tertinggal, hal ini menunjukkan bahwa pemanenan stevia memerlukan ketinggian minimal 15 cm dari permukaan tanah.
