Abstract

The main function of a bank is based on banking law no. 7 of 1992 is as an intermediary institution. As an intermediary institution, banks must be able to maintain profitability ratios and capital adequacy ratios. This is because the capital adequacy ratio of a bank is an important benchmark for consumers or users of these banking services. The focus of this research is to determine how much influence the profitability ratio of a bank, namely the ratio of NIM, OEOI and ROE to the Bank's Capital Adequacy, namely the CAR variable. The research method used is quantitative analysis using multiple linear regression. The results showed that all profitability ratios had a simultaneous effect on bank capital adequacy. Meanwhile, for the individual effect, only the ROE variable has no effect, while the other variables, namely NIM and BOPO, have a partial effect on CAR.

Abstract

Farmers' household income is an indicator of the level of prosperity by looking at the amount of expenses and family expenses. Mango production, which has increased every year, needs to be assessed according to the level of household poverty. The purpose of this study was to determine the household level of mango farmers in Situbondo Regency. The research location was determined purposively in the Makmur Jaya I Farmers Group, Jangkar District, Situbondo Regency. Population and sample with saturated sampling technique with a population as well as a sample of 25 respondents. Data were collected through primary data (direct interviews using a questionnaire) and secondary data from related agencies and literature related to this study. The data were analyzed by using quantitative descriptive analysis which was measured using Sajogyo's poverty theory. The prosperity level of the members of the Makmur Jaya I Farmer Group is in the decent living category of 64% and the moderate category of 36%.

Abstract

Utilization of ultisols in Southeast Sulawesi may be approached by inoculating viable arbuscular mycorrhizal fungi (AMF) exposing plant growth-promoting activities to the growth of native economical plants. This study investigated a combination of AMF and liquid organic fertilizers from coconut husks to improve the growth of soybean plants grown on ultisols as one of the potential marginal soils in the region. The coconut husk served as an abundant, cheap, yet potential source for the preparation of liquid organic fertilizers. This study used two factorial design with four treatment levels. The first factor was designed for different AMF species (10 g/pots): control (M0), Acaulospora delicata (M1), Septoglomus constrictum (M2), and Claroideoglomus etunicatum (M3) while the second factor was designed for different concentration of liquid organic fertilizer (mL/pots): control (P0), 150 mL/pots (P1), 200 mL/pots (P2), and 250 mL/pots (P3). Based on ANOVA results, the independent application of AMF species and liquid organic fertilizers gave significant results in regards to the experimental variables such as plant height, number of leaves, leaf area, and stem diameter. The best combination of treatment was observed in the treatment using Septoglomus constrictum with the concentration of liquid organic fertilizer of 250 mL (M2P3) to yield the highest growth performance of soybean plants on ultisols.

Abstract

This study reports the development of an adaptive collaborative learning framework in the industrial era 4.0. The development of learning models in schools is determined by the ability of teachers in pedagogy and the ability of the technology used. The purpose of this study is to develop a collaborative learning model in terms of student-centered learning in addition to interactive learning that will determine the success of the learning management system. Respondents of this study were 310 primary school teachers in West Jakarta, DKI Jakarta Province. The research methodology used the Structured Equation Model (SEM), Obtained by using the fit model testing 72.01% and 66.45% and r square as much as 110.86% and 94.16% for the parameters of Collaborative Learning and Learning Management System. This study uses a standard loadings factor of 0.7. The results showed that all loadings factor values for each indicator were> 0.7. Research findings indicate an influence between interactive learning, collaborative, user-centered learning, and learning management systems.

Abstract

Many infant mortality rates are due to premature events. Premature babies are at high risk for hypothermia and hyperbilirubinemia. To overcome this, an incubator can be used as a warmer and light therapy as blue light therapy for yellow babies. However, both medical devices have still been found using manual control. If the health worker is tired of working and manually controlling both devices, it can put the baby at risk. Multifunctional infant incubator based on ESP32, which is an infant incubator equipped with phototherapy and a mechanical swing. This multifunctional baby incubator has the ability to warm the baby's body, the baby yellow light therapy, and can calm the baby when crying. This tool can be monitored remotely using the Internet of Things (IoT). The sensors used are the DHT22 sensor and the sound sensor. Multifunctional baby incubator can make it easier for hospital or basic health care facility level to monitor baby's health in real time without being at the device location and the resulting data can be stored neatly.

Abstract

Anemia is a health problem in this world, especially in developing countries where an estimated 30% of the world population suffers from anemia. Pregnant women are the most vulnerable to malnutrition because there is an increase in nutritional needs to meet the mothers and a fetus needs during pregnancy. One of the alternatives to overcome iron deficiency anemia is the fortification of foods that are consumed by many people, namely sweet potatoes. The aims of this research was to determine the effect of consumption of sweet potatoes processing on hemoglobin levels of multiparous mothers. This research was conducted for 1 year consisting of the first stage, namely determining the research sample based on the criteria of 32 samples, the second stage was giving informed consent and determining the intervention given, the third stage with the type of research used was Quasi-Experimental research with pretest-posttest only control group design, The design was to measure the hemoglobin levels before and after the intervention giving sweet potatoes for 2 weeks in the control group and the intervention group. The fourth stage was processing the data by using the paired T-test and independent T-test. The results of statistical tests used the paired T-test showed that in the control group the value of ρ = 0.005 <α = 0.05 and the intervention group ρ = 0.000 <α = 0.05. And the results of statistical tests used the independent T-test obtained a value of ρ = 0.008 <α = 0.05, which means that there is an influence between sweet potatoes procesing and an increase of Hb levels for multiparous pregnant women at Minasa Upa Public Health Center of Makassar.
