Abstract

Pakcoy (Brassica rapa L.) or commonly called mustard spoon includes vegetable plants that are heat resistant, so that they can be planted in the lowlands to highlands The production of packcoy plants experiencing ups and downs in 2010 is the peak production of 141.25 quality / ha and continues to decline to 2014 became 114.35 quality / ha. Efforts to increase packcoy production can be done by using organic fertilizers from agricultural waste, manure, green manure, human waste, and compost instead of nutrient sources. This study aims to determine the response of growth and production of Pakcoy plants to the provision of NASA POC organic fertilizer. This study uses factorial randomized block design consisting of 2 treatment factors, namely: Chicken Cage Organic Fertilizer (A) which consists of 3 levels, namely: A0 = 0 tons / ha, A1 = 15 tons / ha (158 g / polybag), A2 = 30 tons / ha (316 g / polybag). NASA POC concentration (N) consists of 4 levels, namely: N0 = 0% (control), N1 = 1 cc / liter of water, N2 = 2 cc / liter of water, N3 = 3 cc / liter of water. The results showed that NASA's POC showed a significant effect on pakcoy plant height, the use of liquid organic fertilizer dosage (2cc / ltr) had a significant effect on plant height. The highest pakcoy plant height is found in the treatment of N2 (2 cc / ltr) of 25.50 cm. The net weight per plot was obtained at the N2 treatment of 262.92 grams

Abstract

Various fruit flies are in Indonesia, but only a few species of fruit flies have been found at the red guava plant in Deli Serdang District. Knowing the species of fruit flies are needed to do the proper control. In addition to morphological identification, it is necessary to carry out molecular characterization to obtain accurate results in characterizing species differences. This study aims to identify the fruit fly based on morphology and molecularly PCR-RAPD for mapping the genetic closeness of the relationship between individual fruit flies. Bactrocera morphologically identified at LIPI, namely B. carambolae, B. papayae, B. caudata, B. albistrigata, B. umbrosa, B. curcubitae, B. tau, and B. kinabalu. For molecular identification PCR-RAPD, shows the dendrogram results from the Neighbor-Joining analysis based on RAPD markers of DNA band characters showing the genetic proximity of eight species divided into three groups of Bactrocera based on their location. The closeness of genetic relationships between individuals was analyzed using Pairwise Distance Calculation which describes the genetic distance between species. The results of Pairwise Distance Calculation ranged from 0.13-0.42. By knowing what species there fruit flies are in red guava plantations in the Deli Serdang district, it can make it easier for farmers to monitor and control fruit flies in red guava plantations.

Abstract

Indonesia has experienced a decline in green bean production due to unsuitable green bean cultivation and low soil fertility. However, combining NPK Mutiara and organic fertilizer made from active maja fruit containing NPK Mg and Fe can increase soil fertility and quality in an environmentally friendly way. This study aims to examine the effect of combining organic fertilizers with active ingredients of maja fruit and pearl NPK in increasing the growth of green bean varieties of VIMA-1. The research was carried out in Sukajadi Village, Perbaungan, Serdang Bedagai District, from October to December 2021 using a 2-factor RAK design where the first factor was PO application with four treatment levels, namely M0 = Control; M1 = 100ml PO: 750 ml water; M2 = 100 ml PO: 1500 ml water; M3 = 100 ml PO: 2250 ml water. Then the second factor is the dose of NPK Mutiara fertilizer where P1 = 30g/plot and P2 = 40g/plot with the number of replications 3. The results showed that the administration of PO with the active ingredient of maja fruit had an insignificant effect on all parameters observed. However, the NPK fertilizer treatment had a significant impact on diameter. Stems at treatment P1 = 30g/plot.
