Abstract

Chinese Cabbage is a perishable commodity perishable because it has the characteristics of a living being and does not have the ability to sustain its life. In general, mustard greens are only stored in sacks. This method can cause damage to the mustard leaves and damage to other parts. Therefore the aim of this research is to analyze the freshness of the vegetables after they are harvested and given supply plant nutrients to extend the shelf life of vegetables. This study used a completely randomized design with 6 different treatments. In the first treatment (A) it was carried out with a box filled with clean water without nutrients. The second treatment (B) to the 5th treatment were sequentially added AB mix nutrition of 2 ml, 5 ml, 10 ml and 50 ml. Treatment 6 (F) was stored without water. Observations were made every 2 days for 6 days so that the total observation was 12 days and stored at room temperature. All treatments were repeated 3 times to obtain 18 experimental units. The results showed that the provision of 5 ml of nutrition had an effect on freshness as indicated by a low weight loss and root growth. Provision of more than 5 ml of nutrients in maintaining the freshness of the chinese cabbage has a bad impact because it causes rotting of the chinese cabbage. Keywords:  Chinese Cabbage, Effect, Freshness, Nutrition, Storage.

Abstract

Mint (Mentha piperita L.) is one of the aromatic herbs. The aim of this research was to investigate the effect of organonitrophos (organic fertizer) and irrigation water volume on the growth and yield of organically cultivated mint. The experiment was conducted in a completely randomized design (CRD) with two factors, namely the dose of organonitrophos consisting of 4 levels: D0 (0%), D1 (10%), D2 (30%), and D3 (50%) of the total weight of the media, and irrigation volume consisting of I1 (20-40%), I2 (50-70%), and I3 (80-100%) of the field capacity. The results showed that the dose of organonitrophos fertilizer and irrigation water volume affected the growth and yield of mint. The treatment that statistically produced the highest oven-dried weight (18.67 grams per plant) was D3I2 (50% compost fertilizer and 50-70% irrigation water). The treatment that produced the highest fresh weight (104.7 grams per plant) and was the most efficient was D2I1 (30% compost dose and 20-40% irrigation water). However, as a consequence, the choice of D2I1 significantly reduced the weight of oven-dried yield to 13.33 grams per plant.  Keywords: Organic, Mentha, Piperita, Organonitrofos, Irrigation

Abstract

Water is a natural material that is very important for humans, animals and plants. Apart from being used as consumption, water can also be used as an energy source, with the need for water use which is very important for humans, it needs to be supported by an increase in water supply. Water supply usually uses a pump that functions to raise water from a lower place to a higher place. However, there are still many people who still have difficulty meeting their water needs due to the weak purchasing power of the people to buy pumps, especially in rural areas. Therefore, it is necessary to design a hydraulic ram pump which is one solution to overcome this problem because it is cheap and simple to manufacture and maintain. A hydraulic ram pump is a pump that can raise water from a low place to a higher place using energy that comes from the water flow itself. To find out the performance of the hydraulic ram pump, a pump efficiency test was carried out with the treatment of different heights of water flow sources, different heights of water lifted and different exhaust valve loads. The results of efficiency testing are obtained that the higher the water flow source the greater the efficiency, the lower the water lift the greater the efficiency and the lightest load on the exhaust valve has the greatest efficiency. Keywords: water, pump, hydraulic ram pump, efficiency

Abstract

The taste of crackers can be varied by mixing two or more raw materials. Crackers can be made from a mixture of melinjo flour and cassava (gaplek) flour. The purpose of this study is to know and indentify the physical characteristics of crackers made from a mixture of melinjo flour and geplek flour.This study used a completely randomized design (CRD) with 6 different treatments, these are the mixture of melinjo flour and gaplek flour P1(100%, 0%), P2 (80%, 20%), P3 (60%, 40%), P4 ( 40%,60%), (20%,80%), P6(0%,100%). This study uses several parameters to be measured such a hardness, density, color, taste, and crispness. The result of this study showed that the hardness of each treatment is relatively the same. The density of crackers showed that the higher the melinjo flour content, the higher the density. There was a change in the color of the crackers before and after they were fried. The results showed that the concentration of 20% melinjo flour and 80% cassava flour were the most preferred types of crackers by the panelists. Keywords: Crackers, Gaplek, Melinjo, Physical Characteristics And Mixture

Abstract

The growth of development that continues to increase in each region results in reduced water catchment areas, to overcome this it is necessary to create artificial recharge. Artificial infiltration aims to preserve groundwater as a source of life to be maintained, for reasons of beauty many building service users prefer paving blocks as an alternative to pavement covering the ground surface, installations that have gaps on the sides of the paving can transmit water by 30-50% . Paving block is a building material composed of portland cement, aggregate, water, with or without additives but does not reduce the quality of the paving itself. Porous paving blocks are paving blocks made from added materials in the form of biomass waste, one of which is teak wood sawdust. This research was conducted to make porous paving blocks with quality standard D, which are used for parks floor and other uses. The composition of the materials used were cement and sand (1:3), added with teak sawdust in the treatment of P1 as much as 2%, P2 as much as 4%, P3 as much as 6%, and P4 as much as 8% of the total weight of the material 2.5 kg. Based on (SNI 03-0691-1996), paving block sizes have a minimum thickness of 60 mm with a tolerance of ±8%. The porous paving block produced meets SNI standards with side lengths of 100 mm and thicknesses varying between 56 – 72 mm. Paving blocks with quality standard D have a minimum compressive strength value of 8.5 MPa and a maximum water absorption capacity of 10%. The results of this research shown the paving block P1 treatment has an average compressive strength value of 16.05 MPa with an average water absorption capacity of 6.89% which are in paving block type D quality standard range. Keywords: Leachate, Paving Block Porous, Teak Wood Sawdust, Waste.

Abstract

Way Tenong Subdistrict is located in West Lampung Regency with an area of ± 11,700 Ha, with relatively unstable soil types and wavy and hilly terrain, making Way Tenong Subdistrict risk to threats from soil activity such as landslides. In 2022 there was a landslide in Way Tenong District which caused damage and fatalities. Because of this situation, some experiment is needed to determine the points that have the potential to experience landslides and the factors that are most dominant in the occurrence of landslides in Way Tenong District, called mapping by utilizing the Geographic Information System (GIS) and Landsat Imagery. The method used in this study is the overlay method (Union) with six parameters, namely slope, soil type. In this study the scores for each class of parameters were added up using a field calculator on the attribute, so that landslide intervals were produced which were divided into five landslide hazard classes, namely not prone, low vulnerability, moderate vulnerability, prone and very vulnerable. From the results of the study it was found that Way Tenong District only had four levels of landslide vulnerability, namely low vulnerability of 176 Ha or 1.50%, medium vulnerability of 5,537 Ha or 47.10%, vulnerability of 4,448 Ha or 37.83% and very vulnerable area of 1,596 Ha or 13.57%, and it can be seen that the dominant factor in the occurrence of landslides in Way Tenong District, West Lampung Regency, is the type of soil. Keywords:  Mapping, Geographic Information System (GIS), Landsat Imagery, Overlay
