Abstract

Lettuce is a type of vegetable that is produced in a hydroponic system, one of which is a static hydroponic system. Hydroponic lettuce production usually uses a certain level of concentration. This study aims to determine the effect of the hydroponic system, concentration levels, and their interactions on the growth and yield of lettuce. The research was carried out in the research and experimental garden of the Faculty of Agriculture, Fisheries and Biology, University of Bangka Belitung, using a factorial randomized block experimental design including a static hydroponic system and various concentrations of Huett's lettuce formulation, repeated 3 times. The results showed that the kratky hydroponic system was the best treatment. The concentration level of 500 ppm showed the highest mean yield. The combination of kratky hydroponic system treatment with a concentration of 500 ppm showed the highest average yield on the growth and yield of lettuce.

Abstract

Fall Armyworm (Spodoptera frugiperda J.E. Smith) is a new pest species in Indonesia which has the potential to attack corn plantation in Mendo Barat District because it has the highest harvested corn area in Bangka Regency. The purpose of this study was to determine the attack intensity, Symptom Characteristics and distribution of S. frugiperda on corn plantations in Mendo Barat District, Bangka Regency. The study had been conducted in November 2019 to February 2020 using the observation method. Study sites and sampling techniques was carried out by using purposive sampling technique. The results showed S. frugiperda larvae had the same characteristics as those found in Africa, namely the inverted Y pattern on the head, four black dots on the eighth dorsal segment, thick bands on the lateral part and three bright lines on the upper body. Symptoms of an attack in the early vegetative phase of corn were transparent holes in the leaves and shoots, while in the reproductive phase were damaged cob and corn kernels. The number of caterpillars, the highest number of plants attacked and damaged were found in Petaling Banjar Village by 55% intensity of severe attacks. The intensity of relative damage was at 31.6%. Most of the plants attacked and damaged by S. frugiperdawere found mostly in the tasseling and silking (R1) phase and monoculture planting systems. We conclude the S. frugiperda attacked the corn plants in Mendo Barat District and caused various kinds of damage in accordance with the growing stage of corn plants.

Abstract

Rice wastewater and banana peel extract contain nutrients needed by orchid plants such as carbohydrates, nitrogen, phosphorus, magnesium, potassium, sulfur, iron, and vitamin B1. The use of these two materials as a source of fertilizer can reduce the use of inorganic fertilizers and be more environmentally friendly. This experiment aims to obtain the best frequency of watering rice wastewater and banana peel extract for Dendrobium orchid plants' vegetative and generative growth. Giving rice wastewater every 4 days has the best vegetative (plant height) and generative growth (flowering initiation) when compared with intervals every 2 and 6 days. The application of banana peel extract shows that treatment every 10 days has the best vegetative (plant height) and generative growth when compared to the treatment every 5 days and 10 days. There is no real interaction between rice wastewater and banana peel extract. Too frequent application of both rice wastewater and banana peel extract causes orchid plants to experience growth inhibition due to high moisture on media and plant surface.
