Abstract

This study focused on delineating the groundwater potential and recharge area for Kaffa Zone by the method of remote sensing and ArcGIS 10.4 software analysis techniques. There are six main influencing factors (rainfall, slope, land use/cover, lineaments, drainage density, and Lithology) selected for groundwater recharge zone mapping. The thematic maps were scanned, geo-referenced, and classified as suitable for groundwater using ArcGIS 10.4. The methods to assess the potential zone were using weight overlay analysis and hierarchy of analytical process algorithm. The result obtained the potential of ground water were discussed recharge zones into four major categories: very good, good, and moderate and low. This can help for better planning and management the potential resource of groundwater. The results analyzed the groundwater potential that were subdivided in to low, moderate, high, and very high groundwater potentials areas that cover 1664.1,7682.9, 958.27, and 192.78 km2 respectively.

Abstract

As the challenges toward increasing water for irrigation and water scarcity threats become more prevalent, knowledge of crop yield response to water can facilitate the development of irrigation strategies for improving agricultural productivity.  Experiments were conducted to to compare water usage of several irrigation treatment on rice growth performance and productivity and its water use efficiency.  These experiments were conducted using Situbagendit rice variety (115 day length periode), Urea and Tri Super Phospate fertilizer.  Fertilizer dosage follows fertilizer recommendations for rice, i.e : Urea 250 kg/ha, SP-36 100 kg/ha and 100 kg KCl/ha. Irrigation started from land preparation. controll block (deep flooding) was flooded by a water height of 7 cm. Low level continues flow block was flooded by a water height of 3-5 cm. The volume of water used to saturate the soil of the saturated block was estimated. The number of days of non-flooded soil in AWD before irrigation is applied can vary from 1 day to more than 5 days.  The results showed that total volume of water supplied during the rice growing period in the control block was  2,761.91 m3. Total water volume related to the low level continous flow irrigation block was about 1,217.03 and only about  638.98 m3 for the alternate wet and dry irrigation block. Total volume supplied for soil saturation treatment was about 549.74 m3. Regardless the performance of rice crop growth, it’s the most efficient treatment in terms of water use. It only required an amount of water around14-20 % of amount of water consumed by the continuous deep flooding treatment.  The rice yield of deep flooding irrigation treatment was equivalent to 5.6 tons/ha of dry paddy while the yields of low level continuous flow irrigation,alternate wet and dry irrigation and soil saturation treatments reached 5,3 tons/ha,3.36 tons/ha and 2.80 tons/ ha respectively

Abstract

Mangrove is a plant generally located in tropical regions. It grows in areas with salinated to fresh water and affected by tidal along with anaerobic soil conditions, where many grow in areas that are filled with mud and contain organic material. In the process of photosynthesis, mangrove captures carbon in the atmosphere and are stored in biomass and sediment. Sediment can store carbon greater than biomass and is rich of organic matter. Research regarding carbon storage in mangrove sediment on Payung Island has never been carried out which made this research aimed to estimate carbon storage in mangrove sediment on Payung Island. This research was conducted in October 2020 on Payung Island, South Sumatra and sediment samples were analyzed by the Walkley-Black oxidation method and the sediment texture was analyzed by the Shepard triangle method. The calculation results show the dominant sediment texture was in the clay category, the average value at each station for % C organic is 5,04% and % organic matter is 8,18% and carbon deposits in sediment are 129,6 tonC/ha.

Abstract

Abstract: Scylla serata shell was decomposed at various temperatures ranging from 700-1100 oC to obtain calcium oxide. Calcium oxide from decomposed Scylla serrata shell was characterized through X-Ray analysis, FTIR spectroscopy, and morphology analysis. Furthermore, decomposed Scylla serrata shell was used as catalyst for transesterification of tropical edible oils to form biodiesel. Biodiesel was characterized through density, viscosity, fatty acid value, and iodine number. The results showed that decomposed Scylla serrata shell at 900 oC could produce calcium oxide similar with standard, which was indicated from X-ray powder diffraction pattern of decomposed shell with JCPDS data. FTIR spectrum showed that main vibration of calcium oxide was observed at 393 cm-1. Morphology analysis using SEM indicated that uniform calcium oxide was obtained after decomposition. The use of decomposed shell as base catalyst for transesterification of tropical edible oils resulted biodiesel with density, viscosity, fatty acid value, and iodine number appropriated with SNI standard.Keywords: transesterification, edible oils, biodiesel, Scylla serrataAbstrak (Indonesian): Scyalla serrata telah didekomposisi pada berbagai suhu dari 700-1100 oC untuk diperoleh kalsium oksida.

Abstract

Abstract Limestone mining activities at PT. Semen Baturaja Persero, Tbk use blasting activity that produces ground vibrations. Based on the measurement result on vibration level, the maximum value for vibration is 4.66 mm/s. The results of the data show that the level of emission has exceeded the standard limits for second class buildings (3 mm/s) based on (SNI) 7571: 2010 while the blasting activity is only 175-300 m from the nearest settlement. Fault Tree Analysis is used to analyze undesired events in a system or work set. Reconstruction of Fault Tree Analysis with Boolean algebra yields 5 event combinations that have the highest chance of generating ground vibrations. The event with the highest failure rate is X11 (the number of bursting holes simultaneously) with failure rate of 0.813 and X12 (fast timing delay) with failure rate (0.750). The USBM formulation obtained 3 mm/s vibration results when the number of bursting holes was reduced from 5 holes to 2 holes/delays with a quantity of 43 kg/delay. Based on Shotplus simulation, the company is advised to replace the blasting delay system from electricity to electronics to produce minimal explosion of ground vibration so as not to damage the environment.Keywords: Blasting, flyrock, Vibration, powder factor Abstrak (Indonesian) Proses peledakan batu kapur di PT.

Abstract

Climate is one of the conditions needed by plants to increase production. Climate change, especially on rainfall has a significant effect on agriculture because it has a strong dependence on the climate element. Rainfall is one of the climate factors that play a role in supporting the availability of water. Conditions in areas with high rainfall intensity can cause the loss of flowers and fruit, and if there is a long dry season it will affect flowering on plants. This study aimed to determine the effect of rainfall on L. domesticum production for 10 years (2010-2019). The study was conducted in OKU and OKI Regencies. The analytical method used is multiple linear analysis and correlation analysis. From multiple linear analysis and correlation analysis results, there was a fluctuation in the intensity of rainfall for 10 years (2010-2019). Based on the regression analysis, rainfall in June for OKU Regency had a significant effect on L. domesticum production while for OKI Regency the significance occurred in December.
