Abstract

Dye Sensitized solar cells (DSSC) can use two types of coloring, namely dyesderived from organic and inorganic materials. The choice of natural dyes ispreferred by looking at the enormous potential of biodiversity in Indonesia,where there are still many untapped especially for plants that have a tendency tobe colored or contain chromophore dyes such as chlorophyll (play a role in theabsorption of light for photosynthesis). The wavelength when characterizing thedye as a solar cell must be in the visible area (400 to 800nm). In this study thenatural dyes used are bebele leaves and kangkung which grow on the island ofLombok. The wavelength obtained for fresh bebele is 553nm, 605 nm and 665nm.The wavelength obtained for fresh kangkung leaf is 664.5 nm with the highestabsorption peak. From the results of the absorption stated that natural dyes havechlorophyll a and b groups which are absorbed in the UV-Vis region 600nm to700nm which means that they absorb the red most strongly. In the measurementof current strength and efficiency with multimeters on organic dyes in a row thatis fresh bebele leaves5 μA /cm2; 0.156; fresh kangkung leaves 4.2 μA/cm2; 0,131;dried bebele leaves 4 μA/cm2; 0.13; dried kangkung leaf 3 μA /cm2; 0.088.

Abstract

Dye Sensitized Solar Cell (DSSC) is a solar cell with a dye as an absorbent of photons from sunlight. Research related to DSSC is still ongoing to find DSSC components that produce high efficiency, but are easy and inexpensive to produce. Polymerization is a combined reaction of several monomers with certain rearrangements. The polymerized monomer is tannic acid which is an organic compound that has about 20 π-π * bonds. The tannic acid produced is then used as a dye in the DSSC circuit. Assembled DSSCs are tested for voltage and resistance using a digital multimeter. The polymerized dyes were characterized using UV-Vis, FTIR. The results of the UV-Vis analysis showed that the batochromic shift occurred in the polymerized dye. The batochromic effect will cause more photons to be converted into electrical energy. The FTIR spectrum is used to confirm the formation of poly-tannic acid. The efficiency of DSSC with polymerized dyes was higher than that of non-polymerized dyes, which was 8.9%

Abstract

The number of internet users in Indonesia has recently increased, currently reaching around 62.1% of the total population. The prevalence of social media use has provided benefits for many stakeholders to be involved in the socialization and promotion of their products and activities. Information regarding the latest government programs and activities is published through the official website of the West Nusa Tenggara Provincial Government and the official pages of each office within the West Nusa Tenggara Provincial Government. The potential of social media needs to be maximized in order to disseminate government programs and activities to the community. Social media offers governments the potential to increase democratic participation by encouraging the public to have a voice in policymaking, working with the public to improve services, gathering ideas, and increasing transparency. This research seeks to apply web scraping techniques to collect data with the aim of monitoring social media performance and identifying factors that are closely related to the level of response elicited by a social media post. The research results show that on average a post on the official page of the West Nusa Tenggara Provincial Government gets around 114.9 likes, 5.1 comments and 11.6 shares. Importantly, one of the important factors that influences the number of likes a post receives is the time it is published. Optimal publication times for the official pages of the West Nusa Tenggara Provincial Government are observed between 06.00-16.00 and 18.00-21.00. By looking closely at social media performance and identifying these influencing factors, social media managers are ready to gain invaluable insights to improve performance by precision and efficacy.

Abstract

Mangroves play a vital role as bioindicator plants in port areas with the potential for non-essential heavy metal contamination. This study aimed to determine the potential for phytoremediation of lead heavy metal in mangrove vegetation resulting from port operations. The research was conducted in the mangrove ecosystem of Lembar Harbor, West Lombok Regency, West Nusa Tenggara, Indonesia. Substrate, leaf, and root samples were collected using a purposive random sampling technique and analysis for testing the lead heavy metal content using atomic absorption spectrophotometry. The results showed that the average heavy metal content of lead accumulated in the substrate in each mangrove stand (14.35 ± 2.711 ppm) was higher than the average heavy metal content in the roots (5.48 ± 2.300 ppm) and leaves (3.55 ± 1.623 ppm). Further analysis showed that nine out of 10 mangrove species act as a phytostabilizer against the lead heavy metal with an average translocation factor of no more than one (0.59 ± 0.176). Only Rhizophora stylosa showed the ability for phytoextraction with a translocation factor more than one (1.488). All types of mangroves in the Lembar Harbor area had a bioconcentration factor lower than one, with an average leaf bioconcentration factor of 0.25 ± 0.115 ppm and a root bioconcentration factor of 0.39 ± 0.161 ppm. The ecological function of the mangroves in Lembar Harbor is more specifically an excluder plant for lead heavy metal bioaccumulation with a biological concentration factor (BCF) < 1 and phytoremediation (FTD) < 1, which can be affected by the low accumulated BCF of leaves and roots.

Abstract

Objective: This study aims to analyze the implementation of Continuity of Care (COC) midwifery care for Mrs. B, a 39-year-old woman (G4 P2012) at 37/38 weeks of gestation with Intrauterine Fetal Death (IUFD) at Notopuro Regional General Hospital, Sidoarjo. The study emphasizes holistic care addressing physical, psychological, social, and spiritual needs. Method: A descriptive case study approach was employed to provide an in-depth analysis of Mrs. B's condition. Data were collected through interviews, direct observations, and medical record reviews. The focus of care included pregnancy management, delivery, postpartum care, and psychosocial support. Results: The COC approach effectively facilitated comprehensive care for Mrs. B, integrating medical management of IUFD and psychosocial support to address emotional distress due to fetal loss and abandonment by her spouse. This care model promoted physical recovery and emotional resilience, contributing to Mrs. B's readiness for future reproductive health planning. Novelty: This study highlights the critical role of COC in managing IUFD cases by integrating continuous, patient-centered care that extends beyond physical treatment to encompass psychosocial recovery. The findings underscore the importance of personalized support systems for high-risk pregnancies to improve maternal health outcomes holistically.
