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. 

The use of pesticides in the agricultural sector results in contamination of foodstuffs by pesticide residues, thus becoming a source of exposure to the body and resulting in health problems. The purpose of this study was to analyse the health risks due to the consumption of foodstuffs containing organophosphate residues in farmers. The design of this study was cross-sectional, employing the Environmental Health Risk Assessment (EHRA). The study population was farmers in the North Dempo District of Pagar Alam. A total of 117 farmers were sampled randomly. Environmental samples consisted of five red chilies and five tomatoes, which were selected purposively. Organophosphate residues were quantified using liquid Chromatography Tandem Mass Spectrometry. Body weight was measured using calibrated body scales. Activity pattern data were collected through interviews using a questionnaire. Data analysis was conducted using the  EHRA formulas. The results demonstrated the presence of Chlorpyriphos in red chillies  at a concentration of 3,05 mg/kg, while Profenofos was found at 0.0731 mg/kg and 0.0118 mg/kg.  The presence of Chlorpyriphos in tomatoes samples at a concentration of 0.4439 mg/kg, while Profenofos was found at 0.0112 mg/kg and 0.2043 mg/kg. The risk quotient  for consumption of red chillies containing Chlorpyriphos was found to be 0.0447, while that for Profenofos was 0.2476. The risk quotient for consumption of tomatoes containing Chlorpyriphos was found to be 0.0302, while that for Profenofos was 2.92. It can be concluded that respondents were at non-carcinogenic health risk due to consumption of tomatoes containing Profenofos.

 Background: Cow’s milk allergy is relatively common among Indonesian infantswho are not exclusively breastfed. Despite extensive hydrolyzed formula and aminoacid-based formula are the recommended nutrition for infants with moderate-tosevere illness, not all parents could provide those specialized formulas, presumablydue to the high cost, low availability and poor palatability. In that case, soy-basedinfant formula could be an alternative nutrition. However, it was unknown whetherIndonesian mothers were aware on that alternative nutrition. Objective: We therefore assessed the knowledge levels of mothers who participated in an online platform of PrimaKu on the usefulness of soy-based infant formula to support growthand development of children with cow’s milk allergy. Methods: The study subjectsappeared to have sufficient levels of knowledge on the usefulness of soy-based infant formula for children with cow’s milk allergy. Results: In addition, by increasing their knowledge on iron and fiber fortification in soy-based infant formula, e.g.,through regular academic presentations, mothers could be more selective in choosing alternative nutrition for children with cow’s milk allergy. Conclusion: Our studysuggested that Indonesian mothers who were active in the online platform of Primaku had sufficient levels of knowledge on the usefulness of soy-based protein formanaging children with cow’s milk allergy. 

The study focuses on addressing fatigue among healthcare workers in Emergency Room (ER), vital in delivering health services but prone to worker fatigue. Using objective measures like cardiovascular load (%CVL) and Bourdon Wiersma test, it evaluates physical and mental fatigue. Leveraging the System Engineering Initiative for Patient Safety 2.0 (SEIPS 2.0) model, it comprehensively analyzes factors affecting fatigue. Data collection includes surveys and statistical analysis through Structural Equation Modeling-Partial Least Squares (SEM-PLS). Results show all workers experience fatigue, with physical fatigue affected by age and gender, and mental fatigue influenced by workload. The outer model analysis confirms convergent and discriminant validity, and reliability of the constructs. The inner model analysis reveals the work system significantly affects fatigue, while the process does not. The study emphasizes the importance of addressing fatigue to improve worker well-being and enhance patient care in ER, providing actionable insights for healthcare organizations.

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.

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.

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.
