Abstract

The use of mycorrhizal biofertilizers in shoot grafting cacao (Theobroma cacao L.) nurseries is one of the efforts made to increase cocoa growth in Sikka Regency. This study aims to determine the effect of the dose of mycorrhizal biological fertilizer on the growth of cocoa seedlings. The study used a randomized block design (RAK) with fertilizer doses of 0 g/polybag (control), 10 g/polybag, 20 g/polybag, 30 g/polybag, 40 g/polybag 50 g/polybag. The results showed that the treatment the addition of mycorrhizae on shoot grafting cocoa seedlings had no effect on all growth variables observed at 30 days after mycorrhizal application and significantly affected all growth variables for cacao seedlings aged 60 days after mycorrhizal application. Giving mycorrhizae to shoot grafting cocoa seedlings at a dose of 50 g/polybag (M5) gave the highest yield for all growth variables of cocoa seedlings aged 60 days after mycorrhizal application, namely plant height 48.50 cm, stem diameter 1.10 cm, and number of leaves 8 ,25 strands.

Abstract

In the midst of the Covid-19 pandemic outbreak that is happening in Indonesia, many impacts are happening to the economy of the Indonesian people, one of which is the orchid plant trader in Denpasar City. This study aims to analyze the percentage of orchid sales in the month before the pandemic and during the Covid-19 pandemic and to find out the impact caused by the Covid-19 pandemic on the sales of moon orchids in Denpasar. The results showed that the total sales of orchids in the month before the pandemic were 3,800 trees, while the sales of orchids for the month of the pandemic in 2020 amounted to 925 so that there was a decrease of 75.65%. There is a significant difference between the receipt of sales of orchids in the months before the Covid-19 pandemic and during the Covid-19 and the impact of the Covid-19 pandemic on the sales of moon orchids, namely the decline in sales caused, among others, a decrease in tourists, the number of hotels closed, the elimination of major events so that causing a reduction in the circulation of money in the province of Bali, including in Denpasar.

Abstract

The Use of “Plant Growth Promoting Rhizobakteri” on Rice Field Seed Cigeulis and Situbagendit Variety on Growth and Outcome. Rice plant is a very important food crop which is the staple food of more than half of the world's population. Rice plants as a rice producers contain nutrients for the human body needs. Rice cultivation affects the availability of nutrients. PGPR is bacteria which has potentiality to forming colonies around the roots to help provide nutrients for plants, facilitate nutrients absorption for plants, and improving the plants’ production. Rhizobakteri is bacteria in rhizosfer which aggressively forming plants’ roots, and give benefits for plants by spur growth. The aimed of this study is to find out the potentiality of PGPR in improving growth and results of rice production. The experimental design that used was randomized block design, with 4 treatments. Growth and the best result that obtained was on treatment (CGIE), which consist of plant height, number of tillers and grain weight. Keywords: Rice, PGPR, Rice Variety and Production Result

Abstract

This study aims to analyze the feasibility of the Nuabosi cassava chips agroindustry with the “Qurena” brand and formulate a strategy for its development. The research was conducted at the Home Industry for Processing Nuabosi Cassava with the brand "Qurena", managed by the PKK Mobilization Team in Randotonda Village, Ende District. The number of employees is 30 people, including leaders and employees. This research is a population study. The analysis used R/C ratio, B/C ratio, ROI, and SWOT. The results of the analysis show that the Nuabosi cassava processing industry into “Qurena” brand chips is profitable and feasible because the R/C ratio is > 1, the B/C ratio value for each production cost is Rp. 100 then will get a profit of Rp. 78, the “Qurena” brand chips business is feasible. The ROI value obtained is 78%, this value can be interpreted that the amount of profit obtained compared to the investment (ROI) invested is good. Each capital of Rp. 100, obtained a profit of Rp. 78. Based on the SWOT analysis it was found that the appropriate development strategy is a progressive strategy that supports the growth of agro-industry businesses, and is in a rapid growth strategy. The Nuabosi cassava chips business with the “Qurena” brand is in a strong position and has the opportunity to be developed.

Abstract

Cadmium heavy metal is one of the heavy metals that is harmful to human health and is widely found in agricultural land with the use of phosphorus-based fertilizers such as in rice fields. The research was conducted in Lape Village, Aesesa District, which produces Inpari and Ciherang varieties of rice. Rice samples were taken directly from the farmers who cultivate the two types of plants. Analysis of cadmium from rice samples using the Atomic Absorption Spectrophotometry (AAS) method and comparing it with the maximum limit of heavy metal contamination in rice set by the Indonesian National Standard (SNI) 6989.16:2009 . The results showed that the cadmium content in rice was < 0.001 ppm – 0.001 ppm. The content of cadmium in the rice is still below the set standard, this is closely related to soil conditions such as soil pH, C-organic at the study site, where high organic matter conditions affect low cadmium content.

Abstract

Excessive use of inorganic fertilizers and intensive tillage can cause changes in chemical properties and soil fertility. This study aims to determine the chemical properties of the soil and the level of soil fertility on land that cultivates vegetables. The research was conducted in Rewarangga Selatan Village, Ende Regency. This research was conducted using a survey method, by taking soil samples by composite methods on spinach, mustard and kale vegetables. The variables observed were soil pH, C-Organic, P2O5, K2O, CEC, and KB. These variables were analyzed for soil chemical properties and then matched using soil chemical criteria and soil fertility from the Bogor Soil Research Center. The results showed that the soil chemical criteria were soil pH in the acidic to very acidic category (4.0–5.0) , moderate C-Organic (2.03% – 2.37%), very high P2O5 (39.53 ppm – 48.90 ppm), very high K2O (1.01 me/100gr – 1.24 me/100gr), very high CEC (40.11 me/100gr – 40.33 me/100gr), and very high KB (82 ,11% - 86.76%) . While the criteria for soil fertility in the cultivation of vegetables are moderate.

Abstract

Soil is one of the main components that affect agricultural productivity. Soil quality certainly needs to be considered as an effort to increase plant growth and production. One of the most influential components of soil quality is the chemical nature of the soil. Research on Analysis of Soil Chemical Content in Horticultural Farmers' Land in Ladogahar Village, Nita District, Sikka Regency has been carried out from October to December 2021. The purpose of this study was to determine the chemical content of the soil in Horticultural Farmers' Land in Ladogahar Village, Nita District, Sikka Regency. This research uses observation methods, literature studies, and laboratory tests. Composite soil sampling using the zigzag method. The results showed that the land had a low C-organic content (1.00-2.00%), a slightly acidic pH (5.6-65), a low phosphorus content (21-40), and a Potassium content in the soil. moderate range (21-40).

Abstract

The production of mustard pakcoy (Brassica rapa L.) depends on the level of soil properties. Therefore, a study was conducted to determine the physical and chemical properties of the soil for mustard cultivation and its relationship. This research is quantitative descriptive. Observation variables in this study were C-organic soil, soil texture, soil moisture content, porosity, and bulk density. Laboratory data from soil physical properties and C-organic soil were matched with soil chemical criteria and evaluation of land suitability, After that, correlation analysis is used to see the relationship. The results showed that the C-organic content of the soil in Wolofeo Village was 3.01%-3.54% and was classified as high. While the physical properties of the soil in Wolofeo Village are for soil moisture content ranging from 39.77% -41.11%, Porosity ranges from 52.42% -61.33%, Fill Density ranges from 1.02 -1.26 g/ cm3, and the soil texture is sandy loam. These criteria are very suitable conditions for the cultivation of mustard greens. The relationship between C-organic soil and soil physical properties shows a significant relationship.
