In response to declining feed gas, Badak LNG currently operates two process trains. The power demand has decreased to only one-third of the total 112.5 MW internal power generation capacity, indicating a significant opportunity to optimize generator usage for improved efficiency and cost reduction. However, reducing the number of active generators may decrease system inertia, making the system more vulnerable to disturbances, especially with the integration of a 4 MWp solar PV panel. Additionally, partial power migration to the public utility company (PLN) further reduces power consumption. This paper presents a comprehensive power system study and reliability analysis, including load flow, transient analysis, and a detailed reliability study. By employing the Loss of Load Expectation (LOLE) method and evaluating several jeopardy scenarios, the study recommends operating five power generators (PGs) for two-train mode. Although the calculated LOLE of 0.56 days/year is higher than the North American Electric Reliability Corporation (NERC) standard of 0.1 days/year for two-train mode, operating with fewer PGs can significantly benefit fuel efficiency. Additionally, considering that only non-critical loads would be affected in the event of load shedding, the proposed strategy is deemed viable. The paper also outlines a maintenance strategy for the power generators in the coming years to ensure sustained performance and reliability.

This study aims to provide empirical evidence regarding the impact of the COVID-19 pandemic on banking performance in Indonesia. This study examines differences in Indonesian banking performance before and during the COVID-19 pandemic. Banking performance in this study was measured using the CAMEL measure. The analysis was carried out by conducting a different test using the SPSS application version 22.0. Based on the results of tests conducted on 205 observations on banking from 2018 to 2021, it was found that the CAR, ROA, ROE, BOPO, LDR, and Customer Deposit levels from banks in Indonesia had a significant difference between before and during the COVID-19 pandemic. However, there was no significant difference between the NPL banking level in Indonesia before and during the COVID-19 pandemic. This proves that the COVID-19 pandemic has harmed banking in Indonesia, so the government must pay attention to the current banking strength to survive and recover after the COVID-19 pandemic.

This study presents a novel approach to synthesizing honeycomb carbon quantum dots (CQDs) from cigarette smoke by a hydrothermal process. A comprehensive characterization of these CQDs, conducted through high-resolution transmission electron microscopy (HRTEM), showcases their unique honeycomb structure, with an average particle size of 6.3 nm. Photoluminescence (PL) in CQDs is a captivating phenomenon where these nanoscale carbon structures emit strong blue luminescence at 461 nm upon exposure to ultraviolet light, with their excitation peak occurring at 380 nm. Fourier Transform Infrared (FTIR) analysis also identifies specific functional groups within the CQDs, offering valuable insights into the mechanisms governing their photoluminescence. Analysis of excitation spectra indicates the presence of both aromatic C=C bonds at 254 nm and C–O bonds from 280 to 420 nm.

The availability of seeds is one of the most essential aspects of agricultural development in developing countries and Indonesia is no exception. This requires adequate technological innovation and institutional support. This study aims to describe the synergy of innovation at the level of national companies that provide hybrid corn seeds to farmers. Three levels of company performance were compared namely well-established companies, middling, and less-developed companies. The results showed the performance of hybrid corn seed companies from 2019 to mid-2022 was mainly influenced by the degree of synergy between seed companies and their supporting institutions in implementing improvements in seed production technology. Established companies have better synergy with supporting institutions, hence, they can adequately apply seed production technology producing 4,900 tons of quality seeds, and distributing them to various regions specifically 12 provinces. Meanwhiles, companies that have low synergies with their supporting institutions are very weak, producing seeds only in small quantities at 400 tons. This implies that technological innovations and institution synergy for hybrid corn seed production can be applied by national companies with adequate support from local institutions.

Physical and psychological stress causes harm to the health status of the elderly with chronic diseases. This study aimed to understand coping mechanisms of the elderly with chronic conditions who live with their family.This study was conducted using a descriptive phenomenology method from the experience of 13 older adults with chronic disease. The study processes were interviewed, tape recorded, transcribed, and explored from the transcripts using Colaizzi's descriptive phenomenological method. The steps of the descriptive phenomenology process are bracketing, intuiting, analyzing, and describing.The coping mechanisms used by the elderly with chronic diseases are (1) the behavioral focus coping ways by doing sports, and physical activities; (2) Focus on spirituality has been implemented by fasting, chanting, dhikr, and prayer; (3) The cognitive focus by working on hobbies or habitual activities and helping each other; (4) The social interaction focus was by interacting with friends, family, and neighbors.This shows that elderly adults with disease conditions try to adapt various forms of coping mechanisms, which positively affects their psychological state. Families which have elderly with chronic diseases are expected to provide nurturing and psychological support to them so that the elderly can consistently apply coping mechanisms to overcome and tackle chronic diseases. Understanding the coping mechanism implementation of the elderly who have chronic diseases by their family can guide health specialists in designing psychological and spiritual approach interventions.

Horse mussels are bivalves found in Kendari Bay and are frequently consumed by the people in the surrounding coastal communities. The population dynamic of this mussel species in Kendari Bay is not yet fully understood. This study aims to determine the size structure, growth, mortality, and exploitation rate of horse mussels in Kendari Bay. This research was carried out in Kendari Bay on the outskirts of Southeast Sulawesi, Indonesia, from January to December 2019. Horse mussel samples of all different sizes were randomly collected from different points of the area of the mussel habitat. The collected samples were counted in total, and their shell length was measured using a caliper with an accuracy of 0.05 mm. The size, growth, mortality, and exploitation rate data were analyzed using the Bhattacharya method, inverse von Bertalanffy, Pauly empirical, and length-converted catch curve accommodated in the FISAT II. The results showed that the horse mussels comprised two dominant size groups, with one dominating most of the months. The asymptotic length (Lo) of the mussels was 9.7 cm, with a growth coefficient (К) of 1.1 yr. Moreover, the growth performance index of the mussels was (@)'=2.01 yr\"!, and the maximum age (Tmax) Was 2.73 years. The generated inverse von Bertalanffy equation for the horse mussels was Lt =9.7-(9.7-0.025)e-!-!. The natural mortality (M), fishing mortality (Е), and total mortality (Z) of the horse mussels were 2.73 yr}, 1.17 yr!, and 3.90 yr\"!, respectively. The horse mussels in Kendari Bay were well within the underexploited category, with an exploitation rate of 0.30.

Leptospirosis, commonly known as rat-urine disease, is a global but endemic zoonotic disease in the tropics. Despite the historical report of leptospirosis in Malaysia, the information on human-infecting species is limited. Determining the circulating species is important to understand its epidemiology, thereby to strategize appropriate control measures through public health interventions, diagnostics, therapeutics and vaccine development. We investigated the human-infecting Leptospira species in blood and serum samples collected from clinically suspected leptospirosis patients admitted to three tertiary care hospitals in Malaysia. From a total of 165 patients, 92 (56%) were confirmed cases of leptospirosis through Microscopic Agglutination Test (MAT) (n = 43; 47%), Polymerase Chain Reaction (PCR) (n = 63; 68%) or both MAT and PCR (n = 14; 15%). The infecting Leptospira spp., determined by partial 16S rDNA (rrs) gene sequencing revealed two pathogenic species namely Leptospira interrogans (n = 44, 70%) and Leptospira kirschneri (n = 17, 27%) and one intermediate species Leptospira wolffii (n = 2, 3%). Multilocus sequence typing (MLST) identified an isolate of L. interrogans as a novel sequence type (ST 265), suggesting that this human-infecting strain has a unique genetic profile different from similar species isolated from rodents so far. Leptospira interrogans and Leptospira kirschneri were identified as the dominant Leptospira species causing human leptospirosis in Central Malaysia. The existence of novel clinically important ST 265 (infecting human), that is different from rodent L. interrogans strains cautions reservoir(s) of these Leptospira lineages are yet to be identified.
