Abstract

Cadmium (Cd) in agroecosystems poses risks to environmental quality, food safety, and public health because of its persistence and toxicity. This study assessed Cd concentrations in paddy soils and rice grains around Limboto Lake, Indonesia, evaluated soil contamination status, determined Cd transfer from soil to rice, and estimated potential health risks associated with rice consumption. A descriptive quantitative study was conducted at three rice-growing sites adjacent to the lake. Composite soil and rice grain samples were analyzed using Atomic Absorption Spectrophotometry (AAS). Soil contamination was evaluated using the Contamination Factor (Cf) and Geoaccumulation Index (Igeo), Cd transfer using the Bioaccumulation Factor (BAF), and health risks using the Estimated Daily Intake (EDI) and Target Hazard Quotient (THQ). Soil pH ranged from 3.5 to 5.0, indicating acidic to very acidic conditions that may enhance Cd mobility and bioavailability. Cd concentrations ranged from 0.23–0.29 mg/kg in soils and 0.0019–0.0024 mg/kg in rice grains, both below environmental and food safety standards. Cf indicated moderate contamination, whereas Igeo classified the soils as unpolluted to moderately polluted, reflecting differences in the sensitivity and calculation approaches of the two indices. BAF values <1 indicated that although pH increases mobility, the current concentrations do not lead to significant bioaccumulation. EDI and THQ were below the safety threshold, indicating no significant non-carcinogenic health risk from current rice consumption. Although rice remains safe for consumption, persistent Cd occurrence in soils and rice suggests a potential long-term environmental concern if accumulation continues. Therefore, regular monitoring and soil management, including liming to increase soil pH, are recommended to reduce Cd mobility and maintain food safety in the Limboto Lake agroecosystem.

Abstract

Tofu industry liquid waste contains ammonia (NH3) and nitrite (NO2-) compounds which can cause pollution if released into the environment without prior processing. Rice husks can be used to make active carbon which acts as a bioadsorbent against various contaminants which is cheap and easy to obtain. The research aims to test the effectiveness of using rice husks in doses of 5 grams, 10 grams and 15 grams as a bioadsorbent on NH3 and NO2- levels in liquid waste at the Rina Tofu Factory. This type of quasi-experimental research with a Completely Randomized Design (CRD) approach. Determination of NH3 and NO2- levels using the spectrophotometric method with three replications. Data were analyzed using the One-Way ANOVA test (? = 5%). The research results showed that the initial concentration of NH3 was 0.16 mg/L and fluctuated after contact with rice husks (5 gram dose: RI = 0.13 mg/L, RII = 0.15 mg/L, RIII = 0.25 mg/L; 10 gram dose: RI = 0.21 mg/L, RII = 0.27 mg/L, RIII = 0.12 mg/L dose 15 grams: RI = 0.32 mg/L, RII = 0.26 mg/L, RIII = 0.30 mg/L). Meanwhile, the initial concentration of NO2- was 0.043 mg/L and increased after contact with rice husks (5 gram dose: RI = 0.091mg/L, RII = 0.138 mg/L, RIII = 0.125 mg/L; 10 gram dose: RI = 0.117 mg/L, RII = 0.151 mg/L, RIII = 0.122 mg/L; 15 gram dose: RI = 0.112 mg/L, RII = 0.137 mg/L, RIII = 0.126 mg/L). There is no difference in the effectiveness of using rice husks on NH3 (?-value = 0.114) and NO2- (?-value = 0.750) levels in liquid waste from the tofu industry. Further research needs to be carried out regarding variations in contact time between rice husks and liquid waste from the tofu industry.

Abstract

The Health Center Management Information System (SIMPUS) is a service for managing patient data starting from the registration stage, examination to patient treatment. The application of SIMPUS needs to be evaluated in order to improve the quality of health services which can be done using the PIECES and HOT-Fit approaches/methods. The PIECES method consists of six assessment indicators including performance, information, economy, control, efficiency and service. The HOT-Fit method consists of four assessment indicators including human, organization, technology and benefits. The aim of the research is to evaluate the implementation of SIMPUS using the PIECES method and the HOT-Fit method at the Limboto Community Health Center. This type of research is descriptive with quantitative methods. The population is all health workers who use the SIMPUS application at the Limboto Community Health Center, totaling 62 health workers. The number of samples is the same as the population, namely 62 people, which was obtained using exhaustive sampling techniques. The data was analyzed descriptively and then presented in the form of a frequency distribution table. The results of the research show that the evaluation of the application of SIMPUS using the PIECES method was obtained by the majority of respondents (53.2%) stating that it was not good, while the majority of respondents (64.5%) also stated that it was not good for the HOT-Fit method. It is recommended that the Limboto Community Health Center improve the quality of SIMPUS by focusing more on routine evaluations, improving HR skills, strengthening integration between applications, as well as improving infrastructure and system security.

Abstract

Work fatigue is a condition of workers who are weakened to do a job and have an impact on decreasing work productivity. Factors that trigger work fatigue include internal factors (age, gender, work position) and external factors (workload, length of work, work period, work shift and work environment). The purpose of this research was to analyze work shifts and mental workload with work fatigue in Water Treatment Plant operators at Perumdam Muara Tirta Gorontalo City using the NASA-TLX and SOFI methods. The type of research used was analytic observational with a cross-sectional research design. The research instrument used the NASA-TLX and SOFI questionnaires. Data were analyzed using the Spearman’s Rank correlation test. The results of the study of work shifts of Water Treatment Plant operators using the fast rotation shift system. Mental workload was mostly in the moderate category with 20 operators (51.3%) and work fatigue was mostly in the moderate category with 26 operators (66.7%). There is a strong relationship between work shifts and work fatigue (?-value = 0.000; r = 0.653) and there is a quite strong relationship between mental workload and work fatigue (?-value = 0.008; r = 0.417). It is recommended that operators be able to adjust their working hours properly to the demands of duties and responsibilities outside of work.
