Abstract

This study aims to control the health and fertility of the soil naturally. This study observed over a period of time through a microcontroller sensor the changes in soil parameters such as: soil acidity level, infiltration rate, electrolyte conductivity level and porosity level observed from the soil infiltration rate. Using the simulation method with two (2) types of bioholes, it can be seen the increase in EC at each depth at a certain time period. This method uses Smart Biosoildam (Biodam) technology which can be simulated to match the actual process (real time). From graphic observations and EC standards, it can be seen that the ability of the soil to provide nutrients in the root growth zone can be used as information to determine the schedule and distribution pattern of planting both during the vegetative growth period and the generative growth period. So that it can be known the effective planting distance and biohole distance in order to be able to provide nutrients during the vegetative and generative periods. The distribution of nutrients can be monitored through sensors that convert analog parameters on the microprocessor into digital information that is sent via wifi in real time. Simulation of sandy beach soil fertility based on the number of microbial population = 108/cfu. Variable 1: Soil fertility value of electrolyte conductivity/EC value at a depth of 26 cm from 780 uS/cm to 1438 uS/cm on day 35 and from 1438 uS/cm down to 1290 uS/cm on day 40. Variable 2: Soil fertility values from electrolyte conductivity / EC values at a depth of 24 cm from 750 uS / cm to 1168 uS / cm on day 35 & from 1168 uS / cm down to 1042 uS/cm on day 40.

Abstract

The Civil Engineering Study Program of Ngurah Rai University (UNR) implements the core curriculum by including Material Mechanics as part of the 2020 curriculum. One of the Learning Outcomes of the Material Mechanics Course (CMPK) is that students are expected to be able to determine the core magnitude (kern) of building structure elements. The fulfillment of CMPK is targeted to achieve a minimum of 90% of lecture participants are able to determine the core magnitude (kern) of building structure elements, but the class action Cycle I with the treatment of including detailed and systematic answer substance requests that describe the complete solution of the problem can only increase the CMPK from 60% to 84%. For the purpose of achieving a minimum of 90% CPMK compliance, a Class Action Cycle II d is carried out by treating Cycle I plus providing examples of relevant questions. The evaluation was carried out using the Alternative Assessment Method to assess cognitive, psychomotor (skill) and affective (attitude) aspects. The results of class actions with structured assignment treatment include detailed and systematic requests for answer substance that describe the complete solution of the problem plus the provision of examples of relevant questions can increase the fulfillment of the CMPK of Mechanical Materials for Students of the Civil Engineering Study Program, Ngurah Rai University reaching 92%. This result is expected to be a reference for other eyes in achieving the CMPK reduction target.

Abstract

This study aims to control the health and fertility of the soil naturally. This research was conducted on litosol land used for plantations by observing the distribution pattern of the electrolyte conductivity level at each soil depth through microbial activity. This study observed over a period of time through a microcontroller sensor the changes in soil parameters such as: soil acidity level, infiltration rate, electrolyte conductivity level and porosity level observed from the soil infiltration rate. Using the simulation method with two (2) types of bioholes, it can be seen the increase in EC at each depth at a certain time period.

Abstract

The objective of this analysis is to improve soil infiltration rate on Laterit agroland with biofertilizer MA-11 on the Biosolids. As a control is original soil without microbial activity triggered. The research was carried out in July to Agustus 2021 at an area of shallot agroland in Blora Districts. The research was to use a double ring infiltrometer to measure soil infiltration with three replications on each distance from Biohole and use electrolyte conductivity meter (EC) to measure soil fertility by salt ion concentration and soil acidity. The measurement was done every five minutes and observation period every fifteen days along forty five days. The results of research show that the highest of infiltration rate, infiltration capacity , fertility & acidity happened on soil which involved Biofertilizer MA-11. The infiltration rate shows a constant value at a level of 57 to 98 cm / hour which is achieved after the 29 th day. Meanwhile, the EC value in stable conditions is achieved on the 29th day with a value between 535 - 785 uS / cm. So that the activity of biological agents on Andosol soil with the infiltration level will be optimal on day 31

Abstract

This study aims to determine the ability of the margel soil layer to distribute nutrients and restore soil health and fertility due to the use of chemical fertilizers and pesticides. This method uses Smart Biosoildam (Biodam) technology which can be simulated to match the actual process (real time). From the observation of graphs and EC standards it can be seen that the ability of the soil to lower the level of acids and increase fertility. Janis this soil until day 42 the soil fertility rate has not reached = 900 uS/cm with microbial populations = 10 3/cfu to support the vegetative growth period as well as in the generative growth period, so that we will know when is the right time to do: soil recovery through nutrient infiltration, early planting of bulbs/flowers/fruits can begin to be conditioned. until mature based on nutritional value observed through sensors that convert analog parameters by the microcontroller into digital information transmitted via WiFi in real time. The initial condition before the simulation of soil fertility values with EC parameters was 444 uS/cm, the simulation results were: Simulation 1 : Nutrient content for generative growth was achieved on day 27 with fertility rate = 1025 uS/cm with Microbial Population 10 8/cfu. Simulation 2: Nutrient content for generative growth was achieved on day 42 at fertility rate = 1100 uS/cm with microbial population = 105/cfu. Simulation 3: the content of nutrients for generative growth cannot be observed
