Abstract

Sweet starfruit plant is one type of horticulture plant that has a 60% rate of flowering caused by pests on the flower so that there is a decrease in sweet star fruit production. This study aims to determine the diversity of pest and predator insects in sweet starfruit flowers and the influence of environmental factors (temperature and humidity) on pests and predator insect visits on sweet starfruit flowers. Observations were made in 3 time periods, starting at 08.00-17.00 WIB for 20 days. The number of plants used in this study were 40 starfruit trees, in one day the observation needed two starfruit trees, for each tree an 30-minute observation was made. Observations were made using sweep net, yellow sticky trap and visually. The recorded environmental physics parameters consist of air temperature and humidity. Based on the results of the study there are 4 types of insect pests and 2 types of sweet flower starfruit predator insect predators. Shannon-Wiener index analysis of insect pests shows the category of low diversity index, low dominance index and low evenness index. Predatory insects show the category of low diversity index, high dominance index and even distribution index.

Abstract

Rice plants are often disturbed by plant-disturbing organisms (OPT) which results in decreased quality and quantity of rice production. efforts to increase the production of materials, in order to obtain production results with high quality and strength is by means of integrated pest control (IPM). The problem of pests and plant diseases is an inseparable part of plant cultivation. The use of biological agents is very cost effective and reduces the negative effects caused by the use of chemical pesticides. Microorganisms are biological agents capable of controlling insect pests. Genus Steptomyces sp. and Trichoderma sp. produce the enzyme chitinase. This study aims to determine the effect of the biological agency application Streptomyces sp. and Trichoderma sp. on the type, composition, and population of insects, the index of pest diversity on rice fields in Mojotengah Village, Gresik Regency. This study used a survey method using direct observation, insect capture was carried out using a sweep net, a yellow sticky trap, and a pitfall trap. The results of research on rice fields with insect populations found on land with biological agency applications were 280 individuals and 775 individuals without biological agency. Application of biological agents to Streptomyces sp. and Trichoderma sp. affect the number of pest populations. Application of biological agents to Streptomyces sp. and Trichoderma sp. effect on the index value of species diversity including the medium category, the evenness index on the two lands is in the medium category, the species richness index shows the high species richness level in both lands, the dominance index shows the value is included in the medium category.

Abstract

Cayenne pepper (Capsicum frutescens L.) is one of the plants favored by the people of Indonesia. The production of cayenne pepper has increased but has not been able to meet the national demand for cayenne pepper, so the government still has to import it. This research aims to determine the effect of frequency of paclobutrazol and dose of NPK fertilizer on the growth and yield of cayenne pepper. The research was conducted in Gresik on November 2020 to March 2021.This research is a factorial experiment based on a Split Plot (RPT) consisting of 2 factors. The first factor is frequency of paclobutrazol (P) and second factor is dose of NPK fertilizer (N) and was repead 3 times. The combination between the frequency of paclobutrazol and dose of NPK fertilizer gave a significant effect on all parameters except the flowering age and fruit maturity. The combination of treatment without the application of paclobutrazol + 24 g/plant NPK 16-16-16 increased plant height by 18% and leaf number by 48% compared to control. The best result is combination of 2 times application of paclobutrazol + 24 g/plant on parameters number of flowers, fruitset, total number of fruits per plant, and total fruit weight per plant. The best results at the NPK dose of 24 g/plant were able to accelerate the flowering age (43.79) day and fruit maturity (86.04) day.

Abstract

Vertiminaponics is a combination of plant cultivation (hydroponics) and fish cultivation (aquaculture) in one place/land arranged vertically. In the vertiminaponic system, the planting medium plays an important role as one of the determinants of plant and fish growth. The purpose of this study was to find the best growing media for pakcoy growth and yield and catfish growth and yield in the vertiminaponic system. This study used a randomized block design (RBD) with one factor, namely the planting medium consisting of four levels, i.e. broken bricks, malang sand, gravel and zeolite. The results showed that the planting medium of malang sand produced the highest total dry weight (12.42 g) and total fresh weight of pakcoy (240.72 g). The zeolite growing media gave the highest weight of catfish in the vertiminaponic system (11.75 kg), but it was not significantly different from malang sand (11.03 kg).

Abstract

Cocoa is a plantation crop that has the potential to increase state income. In Bali, the highest cocoa production is in Jembrana Regency. Increasing the productivity of the cocoa plant can be achieve by using environmentally friendly fertilizer such as Arbuscular Mycorrhizal Fungi (AMF). The aim of this research is to obtain indigenous AMF isolates and their propagation with different planting media and water stress. The research was conducted from July to January 2021. Sampel AMF for islolation and identification was taken from Banjar Pangkung Medahan, Pulukan Village, Pekutatan District, Jembrana Regency, while isolation and identification of AMF was conducted at Agronomy and Horticulture Laboratory, Faculty of Agriculture, Udayana University, Laboratory of Plant Diseases, Laboratory of Genetic Resources and Molecular Biology of Udayana University and Greenhouse of Experimental Garden Faculty of Agriculture, Denpasar. This research used in propagating of spores of AMF was a Completely Randomized Design (CRD) with 2 factors and 4 replications. The first factor was planting medium which consisted of four treatment levels (soil planting medium, soil with sand growing media, soil with compost growing media, and sand with compost soil growing media) and the second factor was water stress which consisted of three treatment levels (ground water content of 100%, 70%, and 40% of field capacity). The results of isolation and identification showed that there were three genera of AMF spores found, i.e. Glomus, Gigaspora, Acaulospora. The results of spore propagation showed that soil and sand growing media with a combination of soil moisture content of 40% water field capacity produced the highest spores, which was 62 spores on average.

Abstract

Coffee is very important agro industry in Bali Province. The coffee center in Bali which is already famous for its geographic indication protection status is Kintamani District, which is the largest producer of Arabica coffee and an icon of Arabica coffee in Bali. Therefore, efforts are needed to maintain coffee production through the selection of fertilizers that do not harm the environment, for example biological fertilizers derived from arbuscular mycorrhizal fungi (AMF). This study aimed to find the best growing media composition and optimal soil water content and the interaction between the two treatments for endomycorrhizal spore propagation. This research was arranged in a completely randomized design (CRD) with 2 factors and 4 replications. The first factor was composition of growing media which consisted of four levels, i.e. Mt (soil only), Mp (soil and volcanic sand with ratio of 1:1/v:v), Mk (soil and compost with ratio of 1:1/v:v), and Mc (soil, volcanic sand, and compost with ratio of 1:1:1/v:v:v). The second factor was water stress which consisted of three levels, i.e. A0 (100% field capacity), A1 (70% field capacity), and A2 (40% field capacity). The highest spore multiplication results were obtained in the combination treatment of MpA0 as much as 55,00 spores with an increase of 120%. Meanwhile the combination treatment of MkA2 produced the lowest spores as much as 34.25 spores with an increase of 37%.
