The development of technology is connected with customer needs for the speed and stability of LTE network access. Ensuring the quality of the LTE network can be done by measuring using the drive test method in the service area. The test drive must be equipped with software such as Nemo Handy and G-Net Track Pro. Nemo Handy is a professional drive test software that is widely used by providers, while G-Net Track Pro is a drive test software that was previously applied in the learning process at the campus. So that the measurement results using Nemo Handy and G-Net Track Pro for RSRP, RSRQ and SINR parameters need to be compared to performance. From the comparison of RSRP between measurements with theoretical stated Nemo Handy measurement results are closer than G-Net Track Pro. For example, the difference between RSRP in the PURADEMAK eNodeB for Nemo Handy was 5.96 dBm and the G-Net Track Pro was 9.4 dBm. This is due to the weakness of the G-Net Track Pro device that does not have the PCI locking feature as in Nemo Handy so that at some point the measurement cannot be compared.

Electricity energy needs in Bali have increased annually by 135,2 GWh, as a result, the State-Owned Electrcity Company (PLN) is being required to add new power plants or the addition of transformer to serve load side fedeers. New transformer have been added to Padang Sambian substation and the reconfiguration of Padang Sambian feeders. The reconfiguration causes the feeder impedance value to change, thus affecting the protection system such as Over Current Relay (OCR) and Ground Fault Relay (GFR). Calculation of current setting and OCR and GFR relay work time can minimize the interference that occurs. The amount of short circuit current that occurs in Padang Sambian fedeers was calculated to determine the value of relay settings. The result of the analysis showed that the OCR current setting value for the incoming side of 0,91 A with Time Multiplier Setting (TMS) was 0,2 SI and OCR on the outgoing side of 2,063 A with TMS of 0,161 SI. The value of current setting for the incoming GFR was 0,01 A with TMS of 0,27 SI and the setting value of the GFR current on the outgoing side was 0,16 A with TMS of 0,106 SI. The result of Electrical Power System Analysis (ETAP) simulation obtained an OCR and GFR coordination curve that did not intersect the Time-Curve Current (TCC) characteristic. This shows that coordination runs well and meets sensitivity, reliability, selectivity and speed requirements.

Drop call is an example of a problem that is often experienced by users of voice telecommunications services. From this condition, this riset raises the topic of drop call analysis on WCDMA networks in the Renon cluster (nodeB MYAMIN_CR, AKABA_PL, and BUNDARANRENON_PL). Data retrieval needed (Call Set Up Success Rate (CSSR), Call Drop Ratio (CDR), RSCP and Ec/No) is done by drive test using G-NetTrack Pro software. Based on the analysis of the results of the drive test, there were 10 drop call problems. The problems indentified cause by missing neighbors, handover failure, bad spot, coverage problems and overshoot. Bad spots, coverage problems, and overshoot are the initial causes of missing neighbors and handovers failure. Missing neighbors and handover failure begins with the poor value of RSCP and Ec/No, so that the cellphone will try to do a handover. To analyze the drive test results, drive test data is carried out using Atoll software. From the comparison found extreme conditions resulting from obstacle which cause a significant difference in value between the results of the drive test and simulation. The high attenuation rate drop call location due to the obstacle also results in RSCP and Ec/No values being obtained when measurements in the field are low. The low parameter values of RSCP and Ec / No then cause a drop call.

The rapid development of cellular communication technology is inseparable from various problems especially on signal quality. In outdoor areas, the performance of eNodeB that is not optimal may cause communication failure. This research was conducted with the drive test on the L_BUNDARANRENON_PL, L_AKABA_PL and L_MYAMIN_CR to obtain signal quality parameters at Renon cluster area. The results of the drive test obtained compared to the simulation using the Atoll radio planning software with the Hatta Cost-231 propagation model and the Standard Propagation Model. From the comparison results, the margin value is used as a correction factor. The comparison results obtained based on the quality of SINR, The result of using the Standard Propagation Model is closer to the drive test measurement results than using Cost-231 Hatta. However, based on the quality of RSRQ, both propagation models yield almost the same results. Here are found that the correction factor for SINR obtained the Cost-231 Hatta propagation model of 6.15 dB and the Standard Propagation Model model of 6.11 dB. While for RSRQ correction factor the margin for both propagation models is -2 dB

The fires of peatlands on oil palm plantations are very vulnerable to occur in the dry season. Fires will arise due to a decrease in the surface of the water resulting in the top layer of peatland becoming dry. Manually monitoring ground level is very difficult. The solution is to make a remote water level monitoring prototype in order to be able to regulate irrigation on peat land and make the system open and close the irrigation door during the dry season and when the rainy season arrives. The design of groundwater level monitoring uses a program installed on the Arduino Uno microcontroller.Water level data is sent by prototype via GSM SIM 800L network, 8 level conditions that have been determined from a depth of 15 cm multiples of five so on to 55 cm. HC-SR04 Ultrasonic Sensor is a detector for water level. Data can be accessed at any time via SMS by sending "Check" to the prototype. The results of the tests performed indicated that the tool can function in accordance with the design and send information as well as receive monitoring orders.
