Abstract

One of the natural disasters that occur in the atmosphere is a volcanic eruption or what is known as an "eruption". The danger of volcanic eruptions can be in the form of hot clouds, ejected material (incandescent), heavy rain of ash, lava and lava floods. One of the active volcanoes and the highest mountain in North Sumatra is Mount Sinabung. Mount Sinabung is included in the category of strato volcano with an altitude of 2,460 meters above sea level and since the 2010 eruption has been classified as a type A mountain. Until now, Mount Sinabung still erupts frequently and releases harmful products for both human health and the environment, such as volcanic ash. This study aims to identify the distribution of volcanic ash resulting from the eruption of Mount Sinabung on August 8 and August 10 2020 by using an algorithm method, namely multispectral infrared or TVAP which utilizes three infrared channels with different wavelengths for each. Based on the analysis that has been carried out, it is found that the direction of distribution of volcanic ash is to the east and southeast of the location of Mount Sinabung. It can also be seen that there are meteorological elements, such as wind and rainfall that occur during an ongoing eruption which have a good impact by reducing the intensity of volcanic ash so that the volcanic ash column thins.

Abstract

Liquid organic fertilizer (POC) is a solution resulting from the decomposition of organic matter containing more than one nutrient element, namely N, P, and K. Fertilizer plays an important role in increasing crop yields, especially in soils with low nutrient content. In this study, 2 planting media were used, namely packaged planting media and planting media taken from agricultural land in Batu City which utilized liquid organic fertilizer (POC) from vegetable waste using local microorganism bioactivators with the aim of determining the effect of POC doses from vegetable waste on growth and production. mustard plants of 10 mL, 15 mL, 20 mL, 25 mL, and 30 mL. The best growth of pakcoy mustard plants using the Batu agricultural land planting medium was the best at doses of 25 mL and 30 mL. Meanwhile, the growth of mustard greens using packaged planting media this time cannot be ascertained at what dose the best mustard greens are, because in this planting medium many samples in polybags died and grew abnormally. Caused by damage to the leaves caused by pests that attack.

Abstract

Liquid organic fertilizer (POC) is a type of fertilizer that contains nutrients that are important in soil fertility and can be easily applied to soil for plant fertility. Utilization of POC can be used in the growth of Andewi (Cichorium Endevi L) which is an agrarian commodity that is in great demand. The purpose of this study was to determine how the effect of concentration, time of application, and soil type on the growth of Andewi (Cichorium Endevi L). Three factors are used in this experimental study. The first factor was the concentration of POC which was divided into five treatment levels, namely 10 mL, 15 mL, 20 mL, 25 mL and 30 mL. The second factor is the application of organic fertilizer which is divided into two levels, namely morning and evening. The third factor is the type of planting media with 2 levels, namely packaged planting media and soil in the pesantren area. Observational data were analyzed using analysis of variance (ANOVA). Analysis results from observations revealed that the concentration of organic fertilizer in liquid form, the time of application of liquid organic fertilizer and the type of planting media had an influence on the number of leaves, plant height and leaf width

Abstract

Market waste in the form of vegetables is an organic material that is of concern considering that this waste is increasing every day and it is increasingly difficult to find a place for disposal and reduces the aesthetic beauty of the city (Giska, 2017). The type of mustard greens waste is an organic material that has the potential to be used as raw material for biogas. This study aims to determine the effect of different variations of mustard vegetable waste and cow dung on the biogas produced. The variation used was a mixture of cow manure with green mustard, chicory and meat mustard with successive ratios of 7:1, 5:1, 4:1. The mixture of ingredients is put into a simple airtight bioreactor and then carried out the fermentation process stage for 15 days. Then check the temperature and volume of gas produced every day and check the final pH. From the results of the study it was found that mustard greens obtained a higher gas volume on the 7th day, which was 690 mL compared to chicory and green mustard, which respectively produced a gas volume of 475 mL and 380 mL on the 8th day.

Abstract

The value of Indonesia's biodiversity is very high as can be seen from the many plant species, especially those that can be used as medicine and food, but have not been explored much. One of the plants, namely cinnamon (Cinnamomum burmannii), is already widely known as a raw material for medicine and food. However, a higher value can be extracted from the cinnamon plant by making it a raw material for aromatherapy medicated oil. With the Quality Function Development method, a number of user requirements and technical requirements are prepared that translate the wishes of potential customers for products that match the target market. From the calculation results, the total absolute weight is 1520 and the total relative weight is 900000 so it is predicted that cinnamon aromatherapy medicated oil products can be accepted by the public
