Abstract

Sweet corn (Zea mays, Saccaharata sturt) is a food crop that is in great demand by people in Indonesia because it has a sweeter taste than ordinary corn. This sweet taste is because sweet corn has high glucose levels. The glucose content of sweet corn per 100 g has a glucose content of 16%. Sweet corn also has high nutritional content and economic value (Hidayah et al. 2020). Dolomite fertilizer is a soil savior from the onslaught of chemicals that function to neutralize soil acidity or increase soil pH. In addition to the application of dolomite fertilizer, N, P, and K fertilizers contain three macronutrients, namely nitrogen (N), phosphorus (P), and potassium (K). This research was conducted in May–July 2023 in the experimental field of the Faculty of Agriculture, Indonesian Community Development University UPMI Medan, on Jl. Pasar 12 Marindal II Village Hall, Patumbak District, Deli Serdang Regency, North Sumatra Province. This research was carried out using a randomized block design (RAK) in a factorial pattern, grouping based on Factor I: dolomite (D), which consists of 3 levels, namely: D0 = no treatment, D1 = 0.5 kg/plot, and D2 = 1 kg/plot. Factor II: application of NPK (N) fertilizer, which consists of 3 levels, namely: N0 = no treatment, N1 = 10 grams/plant, and N2 = 20 grams/plant. The single effect of applying NPK fertilizer at the level of N2 = 20 grams per plant has the effect of increasing the number of pods per sample plant based on the 5% DMRT test. The interaction effect of NPK (N) fertilizer application and dolomite fertilizer application had no effect on plant length, number of leaves, number of pods per sample plant, fruit length, or weight for sample plants.

Abstract

The prediction of the development trend of mustard greens consumption in Indonesia in the next 10 years (2020 to 2029) has a tendency to increase. The use of compound NPK fertilizers and foliar fertilizers can be a good solution and alternative in increasing the production of mustard greens. This research was conducted at Baraya Garden Putra, Cisarua District, Sumedang Regency from June to July 2023. The method used was an experiment with a single factor randomized block design (RBD) with 11 treatments and 3 replications. The treatment consisted of compound NPK fertilizer (100 kg/ha, 200 kg/ha, and 300 kg/ha) combined with foliar fertilizer (1 g/l, 2 g/l, 3 g/l). The results of the study were analyzed using the F test at the 5% level to find out the best treatment, followed by the Duncan Multiple Range Test (DMRT) at the 5% level. The results showed that the application of compound NPK fertilizer combined with foliar fertilizer made a significant difference to the growth and yield of mustard greens. The K treatment with a combination of 300 kg/ha compound NPK fertilizer and 3 g/L foliar fertilizer obtained the highest results on the parameters of plant height, number of leaves, leaf area per plant, leaf greenness level, fresh weight per plant, and crown wet weight.  Keywords : compound NPK fertilizer, foliar fertilizer, mustard greens

Abstract

Banana peels that are not properly managed will cause environmental pollution. The waste still contains high water content and thus contains organic matter in the form of carbohydrates, proteins and fats. To manage the industry, we can turn it into compost with a mixture of M4 as a decomposer.This study aims to produce compost with banana peel and Zpt auxin on the growth of red spinach (Amaranthus tricolor L.). The research design used in the study was a group randomized design (RAK) with 2 factors and 3 levels of treatment.Factor I there is a dose of banana peel consisting of 3 levels, namely banana peel compost with a total of 27 kg of compostP0 = No treatment (control), P1 = 175 grams / plant, 2.5 tons /ha (equivalent to 10 polybags / plant), P2 = 350 grams / plant 5 tons /ha (equivalent to 15 polybags / plant). While the second factor A0 = no treatment, A1 = 250 ml/liter of water (per polybag), A2 = 500 ml/liter of water (per polybag). Thus obtaining 9 combinations. The research parameters were seen from plant height (cm), number of leaves (strands) sample plant production (g), wet weight, root length (cm) and root volume (ml). The provision of banana peel compost and Zpt auxin has a significant effect on plant height, number of leaves, and wet weight.

Abstract

Paddy (Oryza sativa L.) is a staple food crop and the primary source of fuel for the Indonesian economy. One of the many strategies that needs to be developed to decrease yield loss is pest control for rice. An extremely problematic pest of rice crops is the golden snail (Pomacea canaliculata L.). The golden snail attack on rice plants has the potential to reduce yields and even fail to harvest. In most cases, chemical pesticides are still used to control golden snails, but their overuse can lead to pest resistance. The objective of this research was to identify Kipahit leaf extract (Tithonia diversifolia) concentrations effective in reducing golden snail P.canaliculat) mortality and attack intensity on Inpari 32 rice varieties. The study employed a Randomised Block Design (RAK) with 5 replicates and 6 treatments to examine a single factor. Treatment levels A (Control/No Treatment), B (Kipahit Leaf Extract 40 g/L), C (Kipahit Leaf Extract 50 g/L), D (Kipahit Leaf Extract 60 g/L), E (Kipahit Leaf Extract 70 g/L) and F (Kipahit Leaf Extract 80 g/L) had a significant effect on mortality and intensity of golden snail P.canaliculat attack on plants rice (Oryza sativa L.) Inpari 32 variety. Treatment F (80 g/L Kipahit leaf extract) resulted in the highest mortality rate (74.00%) and the weakest attack intensity (59.67%).

Abstract

Mushroom seeds are an important factor to determine the success of mushroom cultivation. The growth of straw mushroom on PDA media is influenced by the degree of acidity (pH). This research was conducted at the Biotechnology and Plant Breeding Laboratory, Faculty of Agriculture, Singaperbangsa University, Karawang, located in Karawang Regency and start from April 2023 – May 2023. The research method used was a Completely Randomized Factorial Design. There are 2 factors consisting of 21 treatments. The first factor was the pH of PDA media which consisted of 3 levels, namely p1 (pH 6), p2 (pH 7) and p3 (pH8). Second factor was straw mushroom isolate which consisted of 7 levels, namely i1 (Parent P), i2 (Parent S), i3 (FP001), i4 (FP003), i5 (FP017), i6 (FP023) and i7 (FP024). Each treatment was repeated 3 times, resulting in 63 experimental units. The effect of the treatment was analyzed by analysis of variance at the 5% level and if it was significant to find out the best treatment it was continued with a DMRT at the 5% level. The results showed that there was an interaction effect between several F3 isolates of straw mushroom (Volvariella volvaceae) Faperta Unsika and different pH of PDA media on the diameter of mycelia colonies, mycelia growth rate and growth rate of mycelia. Treatment of PDA media with pH 8 and straw mushroom (Volvariella volvaceae) isolate Faperta Unsika FP003 gave the highest mycelial growth results with a mycelia colony diameter of 7 cm, a mycelia growth rate of 3.08 cm/day and growth rate of mycelia 2.58 cm/day.Keywords: Isolate Faperta Unsika, Mycelia, pH of PDA Media, Straw Mushroom
