Abstract

The rice fields in Bonto Rannu Village, Kajang District, Bulukumba Regency are dominated by rainfed rice fields. This species has limitations in the dry season because irrigation/agricultural irrigation is completely dependent on rainwater. Therefore, it is necessary to identify alternative irrigation sources for the sustainability of farmers' farming activities in Bonto Rannu Village. This study aims to analyze the quantity of groundwater wells by testing in the form of a pump test (pumping test) with the step draw down method. The optimum discharge (Qopt) of well 1 is 0.01876 m3/s or 67.53 m3/hour with an optimum Sw of 2.891 m. This shows that groundwater in well 1 can be pumped at 67.53 m3/hour with a decrease in water level of 2.891 m with the pump condition still technically safe. As for well 2, the optimum discharge (Qopt) is 0.00318 m3/s or 11.45 m3/hour with an optimum Sw of 2.100 m. These data indicate that there are limited groundwater reserves.

Abstract

This study aimed to identify the distribution of groundwater aquifers and seawater intrusion at the foot of Mount Gamalama on Ternate Island using 2-dimensional electrical resistivity data. This island has experienced significant eruptions that have caused new deposits to form on its body and have caused the formation of an aquifer layer. Small in size but surrounded by seawater, Ternate Island experiences seawater intrusion at the aquifer zones. We researched using 2-dimensional electrical resistivity techniques on nine lines in the eastern and southern parts of the Island, namely the Bandara, FKIP, PDAM, Kayu Merah, Skep, Lapangan Fitu, Sasa, and Takome lines. Each line has a length of 75 meters to 230 meters. This measurement was carried out in the direction parallel to the shoreline using two electrode configurations: the Wenner and the Wenner-Schlumberger. Electrode spacing was 10m. The results showed that aquifer zones with a resistivity value of 10 – 150 Ohm.m exist in the eastern and southern parts of the island. We found seawater intrusion in the eastern part of the island on the PDAM lines with a resistivity value of 1 – 10 Ohm.m. The zones show high conductance values in the low resistivity range of 3.01 to 3.41 Ohms. Visual evidence reveals that this PDAM line locates at the beach, where Ternate inhabitants utilize groundwater excessively through dug wells.

Abstract

This study aims to determine the effect of murottal type sound waves on stem height, number of leaves and number of stalks on peanut plant growth. Using local peanut seeds with the addition of organic fertilizer, urea fertilizer and without the addition of other nutrients. The peanut seeds were treated with 4000 Hz murottal sound with different exposure times and without murottal sound exposure. Peanut seedlings were observed using a camera to obtain images and using measuring instruments to determine the growth of stems and leaves. The results showed that the difference in the effect of giving sound and without sounding could give a change in the average increase of 6 - 9 cm in stem height, the number of leaves experienced an average increase of 4 leaves while the change in the number of stalks experienced an increase of 1 stalk.

Abstract

Puting Beliung is a strong-rotating wind originating from Cumulonimbus clouds with a speed of more than 34.8 knots or 64.4 km/hour that occurs short time. Puting Beliung occurred on November 2, 2021, at 2 pm in the Kampung Dukuh area, Pasirmukti Village, Citeureup District, Bogor Regency (106° 53' 47.99"E and 6° 31' 5.2"S). The research data are surface air observation data from Bogor Climatology Station, Himawari-8 satellite data, and Copernicus CDS reanalysis data. This study aims to analyze the dynamics of the atmosphere during the occurrence of wind phenomena in a tornado in the Kampung Dukuh area, Pasirmukti Village, Citeureup District, Bogor Regency. This study method is a descriptive analysis of Himawari-8 satellite imagery using SATAID software. The results of this study indicate that tornadoes occur due to shear lines and strong-atmospheric lability in the Bogor and surrounding areas, thus triggering the formation of local convective clouds characterized by cloud peak temperatures reaching -69oC.

Abstract

Jackfruit seed has considerable potential to be used as a corrosion inhibitor because its anti-oxidant content can inhibit the corrosion rate of the metal. This study aimed to determine the effect of variations in immersion time on the corrosion rate, the efficiency of jackfruit seed extract in inhibiting the corrosion rate, and the type of corrosion that occurs in high-carbon steel without and with inhibitors. This study used the maceration method to extract jackfruit seeds. It used the weight loss method to determine the value of the corrosion rate in the sample and used SEM testing to determine the type of corrosion that occurred in the sample. This research yielded corrosion rate values ​​in immersion without inhibitor solutions for 10 days, 20 days, and 30 days respectively, namely 263,46 mpy, 365,93 mpy, and 426,92 mpy. Whereas immersion using inhibitor solutions for 10 days, 20 days, and 30 days respectively, resulted in corrosion rate values ​​of 71,62 mpy, 53.41 mpy, and 44.95 mpy. These results resulted in inhibition efficiency values ​​of 72,81%, 85,40%, and 89,47%. The SEM test produced the type of corrosion that occurred in samples without an inhibitor solution, namely pitting corrosion. For immersion in an inhibitor solution, the type of corrosion that occurred was uniform corrosion.

Abstract

Mount Merapi is the highest volcano in Indonesia with an altitude of 2978 meters above sea level. Administratively, Mount Merapi is located in Magelang Regency, Central Java Province. The study was conducted related to the separation of regional anomalies and residual anomalies using gravity data for the case of Mount Merapi. This research was conducted with the aim of being able to interpret the subsurface structure at the location around the measurement. The second-order polynomial method is used in this study in addition to the separation of the Bouguer anomaly. The results of data processing obtained obtained very low anomaly results, which illustrates the presence of molten magma in the measurement area. In addition, there is a very high anomaly value which describes the presence of eruptive material originating from Mount Merapi.

Abstract

The development of the accelerated pace of technology makes people motivated to make new innovations, as well as something that can be controlled automatically. Therefore, we need a sensor that can facilitate human activities, especially in the home light control system. The purpose of this study is to test and analyze the LDR sensor by simulating a software, namely Proteus with different op-amps. LDR (Light Dependent Resistor) is a type of resistor whose resistance value depends on the intensity of light. The method used in this research is an experimental method, namely by conducting repeated tests 10 times for different types of op-amps. The tests carried out here use three ICs that have different types, namely IC LM 358, IC LM741 and IC LM747. The results of this study are the average voltage value generated for the IC LM385 input 2.75 Volt and 4.99 Volt, IC LM 741 input 2.74 Volt and 2.62 Volt and IC OP07 2.77 Volt input and output 2.5 Volts. Of the three IC test results, the largest average voltage value for both input and output is the OP-AMP LM385 IC.

Abstract

Has been design of a length expansion test instrument for metal material based on electric heaters and dial gauge with iron rods metal as the test material. The purpose of this research is to design a metal material length expansion instrument and analyze the feasibility of the instrument. The main components of this expansion test tool use an electric heater and a dial gauge. The function of the electric heater is as a heater on the test specimen, while the dial indicator is used as a measuring device which is an indicator of the long expansion phenomenon. After testing the iron metal, it showed that this instrument worked well in observing the long expansion phenomenon qualitatively. However, the quantitative results show differences, where the coefficient is measured (0.000045/℃) and reference (0.000012/℃).
