Indonesia's aerospace sector plays a crucial role in maintaining national sovereignty. However, the country's airspace is often infiltrated by irresponsible parties, necessitating an effective monitoring system. Unmanned radio-controlled helicopters are a potential solution, although they are limited in range. This study aims to design a long-range control system for radio-controlled helicopters using satellite phone communication, which offers wide coverage and can reach remote areas. The system comprises a remote control, a radio converter circuit, an audio mixer, and a satellite phone. The radio converter functions to transform the radio control signal frequency into its original frequency without a carrier frequency, which is then re-converted to be compatible with satellite phone input for signal transmission. Test results indicate that the system can transmit control signals with adequate frequency stability within the expected range. Despite minor oscillator instability at certain stages, the system overall operates as designed. In conclusion, this satellite phone-based control system effectively extends the operational range of radio-controlled helicopters and serves as a strategic solution for monitoring Indonesia's airspace.

The family is a place where each family member grows and flourishes, a family might be likened to a house that must correlate between every aspect of the element in it. Relationships not only talk about relationships but also talk about correlation that must have a connection between each other. Family circumstances should also emphasize an awareness of the essence of each member of the family, one that must be marked by definite and precise limits on application. A single upbringing is something that has to be associated with essence and boundaries that can set a specific goal. It is essentially the goal of taking control of and fulfilling the duties of each individual inside, that love always hates the basis of the application of foster care, but understanding of excessive affection can lead to parents in providing deviant foster care such as helicopter parenting. In the study researchers would like to try to explore more deeply the matter of the care of the helicopter's helicopter pattern is supported by qualitative and cemented research approaches with a pastoral case-counseling approach. This heatophic fabrication if it is left to disrupt the stability of the family and impact on mental issues that can last personally acceptable.
