Abstract

The estimation of leaf area index (LAI) becomes important as LAI is one of the parameters in analyzing the crop growth model. Crop growth has different characteristics and it’s strongly influenced by environmental conditions and factors. The growth tends to occur in a short period and covers a large area. Therefore, an approach to analyzing the pattern of changes in crop growth based on LAI spatially is needed. Remote sensing offers an effective and efficient approach to monitoring crop growth characteristics, which can be done in a time series with a wide area coverage by detecting and monitoring the physical characteristics of the crop. The most famous and commonly used parameters to estimate LAI are vegetation indices which are usually calculated based on the ratio of the red and NIR wavelength, known as a spectral signature. The objectives of the research are to examine the Spatio-temporal correlation between LAI of three rice cultivars Sentinel-2A based vegetation indices and to select the most optimum vegetation index in estimating LAI. The field experiment was set up comprising 81 plots, each had a size of 10m x 10 m to resemble a pixel of Sentinel-2A imagery. The results of the analysis show that the vegetation index has a strong correlation with LAI. The Comparison of the four calculated vegetation indices in estimating LAI was performed using a linear regression model and followed by comparing R-squared, RMSE, and Correctness. In general, the EVI2 vegetation index provides the most optimum representation in capturing crop growth patterns based on LAI compared to NDVI, ARVI and SAVI vegetation indices calculated from Sentinel-2A satellite imagery indicated by the better-validated model with the result of RMSE value are 1.12 on V1, 1.11 on V2 and 0.70 on V3. The result of EVI2 Correctness also showed the highest value compared to the other vegetation indices with values of more than 60%, 64.15% on V1, 65.51% on V2, and 78.69% on V3. Further analysis by separating two growth stages could overcome the bias that appears in the LAI data for one life of the crop cycle which is indicated by the decrease of RMSE value on each cultivar planted for both vegetative and generative phases, except for cultivar V3 for the generative phase. The separation of data into two growth stages also increase the percentage value of correctness reaching a number above 60% and there was a value that reached 87%.

Abstract

Serntinel 2A provide Normalized Difference Vegetation Index (NDVI) to be used as an estimate of soil fertility, plant varieties and productivity. The weakness of satellite data is that the data obtained is often inaccurate due to cloud cover, especially in tropical countries with high rainfall such as Indonesia. The use of unmanned aerial vehicle (UAV) as an alternative data have limitation as it captured Red Green Blue (RGB) imagery. The research was conducted from July to September 2020 at Pasir Kaliki Village, District of Rawamerta, Karawang Regency, West Java province. The study has discovered that NDVI showed higher number in result of vegetation index compared to Normalized Green-Red Difference Index (NGRDI) with correlation coefficient is 0.94. The regression model resulted as y=4.78x+0.38 and MAPE value expresses as 26.74%, where the regression model with Pearson’s correlation coefficient value is 0.88. A qualitative assessment using statistical data and a spatial assessment using sampled data from the rice vegetation map reveal a high mapping accuracy with the corresponding R2 being as high as 0.74; however, the mapped rice vegetation accuracy might influenced by other physical factors such as water reflectant, sunlight and the RGB camera limitation itself. Nonetheless, the highest values of NGRDI only reach 0.2 while NDVI can attain at 0.9 at the peak of vegetative phase of rice growth stage. This means that Green Band have limitation in detecting vegetation index. In relation to the different approaches performed, it is noted that the average trend line on both NDVI and NGRDI shown the similarity tendency in all growth stage.

Abstract

Abstract Morning Market in Pangkal Pinang is one of the trading centers in Pangkal Pinang which is an area prone to the transmission of the Covid-19 virus. So far, the number of Covid-19 cases in Indonesia has touched 15,211 positive, 1,002 recovered, and 689 people died. The data was taken on April 25, 2020. In Bangka Belitung, there has been a significant increase every year, with data on May 14, 2020 showing the number 29 positive, 5 recovered, and 5 people died. Along with the increasing number of Covid-19 cases in Bangka Belitug, the Department of Mechanical Engineering of UBB is to make Covid-19 medical PPE in the form of a Faceshield that can be used for traders at the Pagi Pangkal Pinang market. This is done, because it is difficult to get PPE at this time and the price sold in the market is quite expensive. By combining medical science with the engineering world, the Mechanical Engineering department of UBB uses the Autodesk Inventor application to carry out the design process so that the results made later are tested, measurable, and safe to use.

Abstract

The Energy Efficient Car Competition (KMHE) is an annual competition organized by the national achievement center (puspernas), Bangka Belitung University regularly participates in the KMHE competition starting from 2015 to 2022, but UBB's KMHE car has not been able to compete to win the category of prototype gasoline, car KMHE has many shortcomings, especially fuel consumption which is still relatively high, namely 130 km / liter, one method of saving fuel consumption is by adjusting the length of time the injector opens (fuel correction). This study aims to determine the effect of the fuel correction value with a variation of 0 , -11, -23, and -27 on fuel consumption. The Electronic Control Unit (ECU) used is a programmable type ECU, the test is carried out at various engine speeds (RPM 1000, 2000, 3000, 4000 and 5000) with a 5 minute test time. The results showed that the most efficient data on fuel consumption was at fuel correction -27 at 1000 RPM, namely 4 ml and the highest fuel consumption was at correction 0 at 5000 rpm, which was 67 ml.

Abstract

In the implementation of this Community Service Program (KKN), the main activities are focused on making egg hatching machines and utilizing these machines for chicken cultivation.Hatching chicken eggs using a hatching machine can be a quick way for the eggs to hatch. Without the help of a hatching machine, the process of eggs becoming chicks will take a long time and the risk of death is greater. For farmers, time is very valuable for the smooth running of the farm business, besides the success of hatching eggs is much greater than the manual method.The implementation of KKN is divided into 4 stages, the first stage is the manufacture of machines carried out before the implementation of KKN as well as the search for egg seeds. The second stage held a socialization on the use of egg hatching machines and how to breed chickens, the socialization was carried out by the East Belitung Regency Livestock Service Office. The third stage is making cages. Cages are made in the homes of lalang villagers who are selected based on an agreement from the village where the selected residents will then use the egg hatching machine to become chicken farmers. The fourth stage is chicken breeding, including feeding and vitamins. The last stage is monitoring, this stage is done to see how the chickens are developing before the KKN is completed.

Abstract

Canopy density is one of the important parameters in measuring the forest conditions. Canopy density can be estimated by using a remote sensing technology system. Light Detection and Ranging (LiDAR) is an active remote sensing system which uses a laser that is emitted by a sensor to the objects on the earth surface. For a wide area, image utilization which solely relies on LiDAR is still relatively expensive, so it is necessary to develop a method that combine LiDAR data with other medium resolution images such as Landsat 8 OLI imagery. Therefore, this research was conducted to obtain the canopy density estimation model from LiDAR and Landsat 8 OLI data. The results showed that the best estimation model at the study site, PT Global Alam Lestari's peat swamp forest was FRCI = - 0.0171 + 8.691 GRVI. The equation model had coefficient of determination (R²) of 50.2%, standard deviation value (s) of 0.101, aggregate deviation (SA) value of 0.459, and correlation coefficient (r) between the actual FRCI and the estimation FRCI (best model) of 0.503.

Abstract

ABSTRACT This study aims to find out: (1) to find out the background of the emergence of the Kebo-keboan tradition in Alasmalang Village, Singojuruh, Banyuwangi. (2) to find out the character values that exist in the Kebo-keboan tradition of Alasmalang Village, Singojuruh, Banyuwangi. (3) to find out the potential of the Kebo-keboan tradition that can be used as a source of learning history in high school. The research methods used are historical research methods with Steps, Heuristics, Observation Techniques, Interview Techniques, Document Study Techniques, Source Criticism, Interpretation and Historiography. The results showed that: Kebo-keboan tradsisi is a tradition born from a water civilization. Water in a civilization plays an important role for life. Many civilizations were born from the flow of water such as civilizations born in the Tigris river valley. The traditional kebo-keboan ceremony is carried out by the osing community in Alasmalang Village, Singojuruh, Banyuwangi, East Java as a repelling ritual and a form of gratitude for a bountiful harvest. This tradition arose as a result of a Tirakat or prayer request made by Great-Grandfather Karti who lived around the 18th century over the plague that hit the village at that time, and an attempt to find a solution due to prolonged crop failure. The people of Alasmalang village believe that for generations if they carry out the traditional Kebo-keboan ceremony will prevent them from all diseases that have plagued their village in the past. This Kebo-keboan tradition takes place in the month of Suro or the month of Muharam in the Islamic calendar. The aspects that can be used as a source of learning history based on curriculum and syllabus analysis are Religious, Social and Cultural aspects which are then compiled in modules as learning supports to be used as a source of learning history in high school.
