Background: Stunting is still one of the focuses of health problems in the world.Stunting is caused by many factors, including access to sanitation. Inadequate access to sanitation can cause infectious diseases that impair nutritional absorption intoddlers during digestion, leading to stunting. Objective: This study examines theconnection between sanitation access and stunting in East Nusa Tenggara Provincealong with its confounding variables consisting of access to drinking water, toddlerage, gender, and residence. Method: The study design was cross-sectional with asample size of 4,224 children aged 0-59 months analyzed from the 2023 Indonesian Health Survey (IHS) data. Data were analyzed using univariate, bivariate (ChiSquare test), and multivariate (multiple logistic regression analyses with a risk factormodel). Results: Studies showed households with inadequate sanitation access canincrease the risk of stunting by 1.56 compared to those with adequate sanitation access. Other factors significantly associated with stunting included toddler age, gender, and residence. The problem of access to sanitation is related to residence anddefecation behavior. Conclusion: Increasing indiscriminate defecation behavior canincrease exposure to pathogens from feces which can cause diseases such as diarrhea, resulting in malnutrition and stunted growth. To reduce stunting in East NusaTenggara Province, the government is suggested to enhance programs to expandaccess to sanitation, especially in rural areas.

This study examines the implementation of the Permissive Overreach Transfer Trip (POTT) Echo scheme with the activation of the Weak-End Infeed (WEI) function on distance protection systems in a 150 kV transmission network to enhance protection reliability and selectivity, especially at substations with weak infeed currents. Before WEI activation, the protection system experienced delays or failures in detecting faults, particularly for faults in zone 2, where the relay tripped with a delay instead of achieving a desired reclose, thereby extending the Transmission Line Outage Duration (TLOD). After WEI activation, test results showed that the relay provided an instantaneous trip response, and the autoreclose function operated after 1000 ms, significantly reducing TLOD. The success of the echo signal ensured smooth communication between relays, supporting efficient protection coordination. Moreover, the selectivity function remained intact. The implementation of this scheme has proven to enhance the reliability of the protection system, offering a more stable and responsive solution for addressing the challenges posed by weak infeed currents.

ABSTRAK
Penelitian ini membahas implementasi skema Permissive Overreach Transfer Trip (POTT) Echo dengan aktivasi fungsi Weak-End Infeed (WEI) pada sistem proteksi jarak di jaringan transmisi 150 kV untuk meningkatkan keandalan dan selektivitas proteksi, khususnya di gardu induk dengan arus infeed lemah. Sebelum aktivasi WEI, sistem proteksi mengalami keterlambatan atau kegagalan dalam mendeteksi gangguan, terutama pada gangguan di zona 2, di mana relay memicu trip dengan waktu tunda, meskipun reclose diharapkan, sehingga memperpanjang durasi gangguan (Transmission Line Outage Duration - TLOD). Setelah aktivasi WEI, hasil pengujian menunjukkan bahwa relay memberikan respon trip instan, dan fungsi autoreclose dapat bekerja setelah 1000 ms, mengurangi TLOD secara signifikan. Keberhasilan sinyal echo memastikan komunikasi antar relay berjalan lancar, mendukung koordinasi proteksi yang efisien. Selain itu, fungsi selektivitas tetap terjaga. Penerapan skema ini terbukti meningkatkan keandalan sistem proteksi, memberikan solusi yang lebih stabil dan responsif dalam menghadapi tantangan arus infeed lemah.

The flow of electrical energy has the potential to experience disturbances which are often caused by short circuit currents between phases or phase to ground short circuits. Maintenance improvements by PT PLN (Persero) Grati Customer Service Unit (ULP) need to be carried out by adding tools to inhibit the blackout process. One of the largest distribution of electrical energy at ULP Grati is the Nguling Feeder, with 24 disruptions occurring in 2023-2024. This interference can be reduced by adding a recloser to the Nroll Feeder. Apart from making additions, it is necessary to carry out an analysis of the determination or placement of the recloser on the Nguling Feeder with the aim of detecting disturbance conditions. Several scenarios can be applied to obtain optimal results by taking into account the selling kWh value, SAIDI SAIFI, and the number of blackout areas as an effort to minimize blackout areas. The broken section method can be a fairly accurate calculation in determining the SAIFI SAIDI value and saved selling kWh. The results of the research show that the use of a recloser and determining its configuration is very important to minimize the outage area. Before installing the recloser, the SAIDI percentage was 43% with an index of 20.76, while the SAIFI percentage was 11% with an index of 5.50. After installing the recloser based on the section rupture scenario, the SAIDI SAIFI percentage decreased, namely: SAIDI 36% with an index of 17.24 and SAIFI 10% with an index of 4.97. This shows that the SAIDI SAIFI target as an indicator for measuring the recloser on the Nguling Feeder is appropriate for determining system reliability.
