Abstract

The Waste is a prevalent problem in Indonesia, causing environmental pollution, diseases such as dengue, malaria, vomiting, and diarrhea, as well as emitting strong odors in residential areas. Waste sorting is an effective solution to address this issue. Implementing the Conveyor-Based Organic and Inorganic Waste Sorting Tool technology at Tanjung Barangan can help to overcome waste problems in residential areas and facilitate the decomposition and recycling process. This research aims to assess the reliability of capacitive, inductive, and infrared proximity sensors in waste sorting. The study found that the system performed well. The capacitive proximity sensor successfully detected organic waste with a success rate of 75%, while the inductive proximity sensor detected inorganic waste with a success rate of 70%. Once the waste is detected, the information is displayed on the LCD screen, and it is sorted directly into the appropriate trash box based on its type, whether organic or inorganic.The proximity sensors have different detection distances: capacitive proximity sensors can detect objects within a range of 0 to 6 mm, inductive proximity sensors have a range of 0 to 10 mm, and infrared proximity sensors can detect objects within a range of 0 to 14 mm.

Abstract

In the modern era, characterized by an increasing demand for mobility and energy efficiency, fast-charging technology plays a crucial role. As the use of electronic devices and electric vehicles continues to rise, the need for more efficient and energy-saving charging systems is also growing. One of the key components in these systems is the lead-acid battery and capacitor bank, both of which have the ability to store and release energy quickly. Therefore, these components are essential in enhancing the effectiveness of the charging process. However, a major challenge in fast charging systems is optimizing the configuration of lead-acid batteries and capacitor banks to minimize charging time while reducing power losses during the process. Addressing this challenge requires an intelligent approach to determining the optimal power distribution path to ensure a stable and efficient charging process. This study utilizes the Ant Colony Optimization (ACO) algorithm to optimize the configuration of lead-acid batteries and capacitor banks in a fast-charging system. The natural behavior of ant colonies inspires the ACO algorithm to search for the shortest path to a food source. This method has been proven effective in solving various complex optimization problems, including power distribution and energy charging. By implementing this algorithm, the system can identify an optimal charging pattern, reducing voltage fluctuations and maximizing energy efficiency throughout the charging process. The primary goal of this research is to develop a fast charging system that is more efficient, energy-saving, and capable of operating optimally under various conditions. By optimizing the use of lead-acid batteries and capacitor banks through the application of the ACO algorithm, this system is expected to accelerate the charging process without compromising reliability and battery lifespan. The findings of this study are anticipated to contribute to the advancement of smarter charging technology, supporting high mobility needs in the modern era, and providing a more sustainable solution for energy management.

Abstract

Cheese processing always produce a liquid by product, called as whey. Whey contains 50% of milk nutrients, but currently in Indonesia whey is not used optimally. Whey contained some lactose, and can be used as fermented media. This study used cheese whey as a fermented media for Streptococcus thermopillus (StRRM01) and Lactobacillus bulgaricus (Lb-RRM01) called as Whey Yogurt (WY). WY compared to fresh whey (control) on this study for skin care, include of acne treatment. Data were analyzed by T-test on SPSS statictical program. The research showed that WY inhibited the growth of bacteria Propionibacterim acnes 4.35 mm, while there was no inhibition on control (P <0.05). Fermentation process increased the antioxidant activity for 27.7%. WY had the good potential for the acne treatment. This study showed that whey had a value-added,furthermore in the future might be used to develop into a natural ingredient cosmetics for skin care.

Abstract

This study explores the application of Augmented Reality (AR) technology as a tool to enhance environmental vocabulary learning and improve the speaking skills of tourism employees in Sumbawa. Given the importance of English proficiency in the tourism industry, many employees face challenges in mastering vocabulary and effective communication. Adopting a descriptive qualitative approach, data were collected through questionnaires and interviews with 16 employees from four tourism sites. The findings indicate that 87.5% of respondents believe AR significantly aids vocabulary expansion, with 75% reporting increased confidence in speaking English. Additionally, 62.5% see AR as relevant to their professional needs, while 50% find it helpful in understanding environmental terminology. Despite these benefits, some challenges remain, including limited access to AR devices and the absence of real-time feedback. The study concludes that AR has substantial potential to enhance language learning by improving vocabulary retention and speaking proficiency. Moreover, integrating AR into tourism training programs could further support employees in developing essential language skills for their professional growth.

Abstract

This study aims to map the strategic response of the Supreme Audit Institution of the Republic of Indonesia (Indonesian SAI) contained in the strategic plan to SDG issues. Then this research analyzes which of the 17 SDGs targets are the focus of BPK's performance audit. Finally, it analyzes the alignment of BPK's strategic responses that appear in the strategic plan document with the implementation of BPK's performance audit related to SDGs. This research was conducted using a thematic analysis approach, using NVIVO software. The results of the study provide input to BPK policy or regulation, namely so that the strategic responses that appear in the Indonesian SAI’s Strategic Plan and the selected audit policies are in line with the concept of Sustainable Development Goals.

Abstract

Probiotics, prebiotics, and immunomodulators like β-glucan have become popular feed additives. Thus, this study examined the effects of a β-glucan product fortified with dietary biomaterials (fats, proteins, and minerals) on broiler chicks’ growth, carcass features, immunological response, white blood cell (WBC) count, and viable count (number of living cells) of lactobacilli. Day-old Ross-308 (n=250) were randomly assigned to 1 of 5 dietary treatments; A= basal diet, B= basal diet + 40 mg/kg of avilamycin, C= basal diet + 250 g/ton β-glucan product, D= basal diet + 500 g/ton β-glucan product, and E= basal diet + 750 g/ton β-glucan product. The starter diet was administered from days 1 to 14, the grower diet from days 15 to 21, and the finisher diet from days 22 to 35. Each treatment had 5 repetitions of 10 birds. On days 7 and 20, all birds were eye-drop inoculated against the Newcastle disease (ND) vaccine. Three chickens from each replication of all treatments were slaughtered on day 35 to examine carcass features and collect ileal digesta. White blood cell and viable lactobacilli counts at the end of the trial showed the effect of β-glucan supplementation. Throughout the trial, β-glucan administration did not increase average daily weight gain. The treatments did not change WBC or viable count; however, lactobacilli count increased (p≤0.05) in treatment group E. Treatment E increased (p≤0.05) ND-vaccination antibody-titers but did not affect immunological organ development. Treatment diet E (base diet +750 mg/t β-glucan product) improved broiler immunity and gut microbiota. In conclusion, the addition of β-glucan to broiler feed enhanced the beneficial gut flora, particularly Lactobacilli and immune response, and may serve as an alternative to antibiotics.
