Abstract

The research was carried out to get information about the improvement of gro-unding resistant value in tower feet of-high-voltage network, 150 kV, along tower trans-mission in power station, Bantul, Semanu. A good grounding system is used to flow cur-rent into the ground and prevent the current flow into the electrical equipment if electrical fault occurs. The result of measurement has shown that ground, type grumosol has a low grounding resistant value <10 Ω because its ground texture of clay has high ability to absorb and keep water and has very tiny particles and colloid property. The grounding resistant values of type regusol, litusol, brown latosol and red mediteran are above 20 Ω because of their ground texture, sand and clay. Chemical and physical reaction will take places in soil with clay structure. Its colloid property can tie/hold ion or water and sometimes free salt. The aim of this research is to get information about resistant value of soil type with almost ≤ 5 Ω by installing grounding electrode made from four galvanis steel coated with bronze with 15 mm in diameter, 10 meter long and two ground rods are parallel connected with 2 m each electrode and use counterpoise grounding system model. The result of the improvement is expected to meet standard requirement, SPLN almost ≤ 5 Ω.

Abstract

Man was created by God with the power to conduct electricity. However the human body still has limitations. The effect of electric shock on the human body is not the same as the reaction, depending on the magnitude of the electric current that passes through the human body is less than 1 mA, the sensation of shock is only felt in the hand. Above 3 mA, it is in the form of a surprise that feels sick and results in an accident. 10 mA or more, the muscle becomes stiff until it can't remove the condenser. If more than 30 mA, paralysis occurs in the respiratory muscles (lungs). At 100 mA to 4 A, it must interfere with the rhythm of one of the heart chambers (ventricles). The potential danger of being electrocuted (Electric shock), being attacked by a spark (Arc Flash) and an explosion of sparks (Arc Blast), is a serious risk problem. The spark triggers an electric short circuit with an Arc Flash level above (10,000 F), hotter than the surface of the sun, which can cause burns to the human body. In order for the user to use the equipment, the equipment and the environment is quite safe, then the safety of humans for the use of electrical energy in the residence, gets a sense of security and from the dangers of danger due to electric accidents. To reduce and prevent unwanted things from happening, regulations, symbols / codes and other signs are made as guidance.

Abstract

The distribution transformer is one of the main components in an electric power distribution system. Without a distribution transformer, consumers cannot use electrical energy directly considering that the operating voltage in the distribution system is 20 KV or what is called a medium voltage network. Disruptions that occur in distribution transformers will result in blackouts and obstruction of the distribution of electricity to consumers so that services for electricity needs will be disrupted. For this reason, routine and scheduled maintenance of distribution transformers is required which aims to prevent sudden equipment damage, as well as maintaining optimum equipment work according to its technical age, and safe for humans and the environment, as well as reliable in the electric power distribution system. One of the causes of disruption and damage to transformers include overvoltage due to lightning, overload and unbalanced loads, loss of contact at bushing terminals, broken insulators and failure of transformer oil insulation. These disturbances cause damage to distribution transformers and stop the flow of electricity. to consumers. In calculating the usage time of a transformer, we can predict the usage time of the transformer from calculating the voltage and current used every day, so if we know the usage time of a transformer, we can prevent damage to the distribution network by replacing the transformer before the transformer is damaged.

Abstract

Generators that use permanent magnets do not require initial excitation to produce voltage. where the generator design is an axial flux type using a ceramic type permanent magnet (NdFeB), and uses two flanking stator rotors. For electricity use, the AC voltage is changed to DC voltage using a rectifier for charging the accumulator. The air gap in an axialflux generator is the distance between the rotor and stator. The air gap is also a place for the magnetic field to move through the coils in the stator which ultimately produces a magnetic flux value which will influence the amount of induced voltage produced. The faster the rotation produced, the greater the voltage produced, but the frequency value will also increase, so that this generator is only limited to 400 rpm rotation, at a frequency value of 50 Hz, producing an effective voltage of ± 22 V with an air gap distance ( δ) is 2 mm, the frequency measurement has an error of 10-20 Hz and an error percentage of 5-10%, with the results of the induced current measurement having the same voltage

Abstract

Objective: This study investigates the social cognitive factors influencing social commerce engagement, focusing on Generation Z users in Indonesia. The objective is to explore the roles of subjective norms, perceived utilitarian value, self-efficacy, and the fear of missing out (FoMO) in shaping purchase intentions on platforms like TikTok. Research Design & Methods: This study uses an explanatory research design to test causal relationships between variables, focusing on Generation Z TikTok users in Indonesia. A non-probability and convenience sampling method was used, with a sample size of 325 respondents, which falls within the recommended range of 100-400 respondents. Findings: Subjective norms were found to significantly influence purchase intentions in collectivist cultures like Indonesia. Perceived utilitarian value, such as convenience and cost-efficiency, also positively impacts purchase intentions. Self-efficacy boosts consumer confidence in navigating social commerce platforms, enhancing purchase intentions. FoMO serves as a crucial mediator, especially during time-sensitive sales or influencer promotions, increasing urgency in purchasing decisions. The intention to buy strongly correlates with actual purchases. Implications and Recommendations: Marketers should leverage micro-influencers to build trust in niche communities. AI algorithms can predict trends from user behavior, while integrating augmented reality (AR) features can improve engagement. Creating exclusive content and limited-time offers can amplify FoMO, encouraging quicker purchase decisions. Clear return policies and product reviews can further enhance consumer confidence. Contribution & Value Added: This study integrates FoMO into social cognitive theory (SCT), offering valuable insights into the psychological factors shaping social commerce behavior. It provides actionable recommendations for marketers to optimize engagement and drive sales.
