Abstract

Klinter River in Nganjuk is subjected to pollution loads from various pollution sources, including domestic and industrial waste. Water quality can affect the condition of Klinter River, which is still used by the local community to support daily activities. The parameters analyzed include TSS, COD, BOD, NO3-, NO2-, NH3, PO4, and oil and grease, taken from data provided by the Nganjuk Environmental Agency. The study aims to assess the carrying capacity of Klinter River by analyzing pollutant loads and the river's assimilative capacity. Regression analysis is conducted to obtain equations and graphs illustrating the relationship between pollutant concentration and assimilation capacity for each parameter. The analysis results indicate that COD, BOD, and NH3 parameters are no longer able to undergo self-purification.

Abstract

The market demand increase in tomato has not been matched by the tomato production. One of the factors of tomato plant production is less than optimal due to lack of potassium nutrition and improper planting media, causing flower loss. The aim of this current study is to evaluate the effect of planting media composition and the dose of KCl fertilizer on the growth and yield of tomato plants. The research was conducted in Jemur Wonosari, Wonocolo District, Surabaya City, East Java, from November 2023 to February 2024. The experiment was designed according to a Completely Randomized Design with two factors, each consisting of 4 levels, and was executed in triplicates. The composition of planting media was the first factor at different ratio of S:GM:RHC with S =soil, RHC = rice husk charcoal, and GM = goat manure. There were 4 media compositions, namely M0 (1:0:0), M1 (1:1:1), M2 (1:1:2), and M3 (1:2:1). The dosage of KCl fertilizer (K) was the second factor, included K0 = 150 kg/ha, K1 = 150 kg/ha, K2 = 200 kg/ha, and K3 = 250 kg/ha. The results showed that the treatment combination of planting media composition M1 (1:1:1) + KCl dose 150 kg/ha was able to accelerate the flowering time of tomato plants.

Abstract

This research was motivated by a decline in performance at Nafisa Production in Surabaya. Because Human Resources are central figures in organizations and companies. For management activities to run well, the company must have knowledgeable and highly skilled employees and efforts to manage the company as optimally as possible so that employee performance improves. The more employees have high performance, the overall productivity of the company will increase so that the company will be able to survive in global competition. The purpose of this study is to determine the influence of motivation and work environment on employee performance. Through the questionnaire method by distributing questionnaire questionnaires to 35 respondents of Nafisa Production employees in Surabaya. Based on data analysis and hypothesis tests simultaneously in this study, it can be found that motivation (X1) and work environment (X2) have a simultaneous effect on employee performance (Y), this can be proven by the F value of the calculation (23,380) the F table (2,034). Meanwhile, the R multiple value of 0.771 shows that the relationship between the independent variable and the bound variable is 77.10%. Meanwhile, the value of the multiple determination coefficient is 0.594 which means that all independent variables can explain employee performance (Y) of 59.40%. Motivation partially affects the performance of Nafisa Production employees, this can be seen from the t-value of motivation (X1) which is greater than the work environment variable which is only 2.918. Thus, it is concluded that motivation and work environment have a significant influence on the performance of NAFISA Production Surabaya employees.

Abstract

This study examines the implementation of the discovery learning theory in science education at Madrasah Ibtidaiyah (MI) and its impact on improving students' science skills. The research method used is library research by reviewing various literature sources such as books, journals, and relevant scientific articles. The findings indicate that the application of discovery learning is capable of enhancing students' science process skills, such as observation, classification, hypothesis formulation, and conclusion drawing. The implementation of this method is carried out through exploration activities, simple experiments, group discussions, and reflections tailored to the characteristics of students at MI. However, the implementation of discovery learning faces challenges such as limited facilities and infrastructure, varying teacher competencies, limited learning time, and diverse student abilities. To overcome these obstacles, strengthening strategies are needed, such as teacher training, the development of simple and contextual learning media, support from school leaders, as well as the integration of technology and parental involvement in the learning process. In conclusion, discovery learning is an effective approach to enhancing students' science skills in MI, provided it is supported by various comprehensive and sustainable supporting factors.

Abstract

Background: Shallots (Allium ascalonicum L.) are a commodity that contributes significantly to the country's foreign exchange, holding high economic value. Rabbit urine, when processed into liquid organic fertilizer, provides plants with the macro and micro nutrients they need. This study aims to investigate the interaction between liquid organic fertilizer concentrations derived from rabbit urine and three varieties on the growth and yield of shallots. Method: The method chosen for this study was a Completely Randomized Design (CRD) consisting of two treatment factors: three varieties of shallots (Bima Brebes, Bauji, and Tajuk) and five levels of rabbit urine LOF concentration (0, 100, 250, 400, and 550 ml/L). and obtained 15 combinations (V1, V2, V3 and K1, K2, K3, K4, K5). Results: Significant interaction occurred in the number of leaves aged 7–14 HST. The Bima variety showed the best vegetative growth, while the Tajuk variety produced the highest number of bulbs. A concentration of 550 ml/l gave the highest results in plant length, number of leaves, and wet and dry weight of the stover. Conclusion: Rabbit urine LOF concentration of 550 ml/l is effective in increasing the growth and yield of shallots, especially in the Bima variety.

Abstract

Aeroponics is cultivation that can produce lettuce optimally. This research aims to obtain the quality and quantity of lettuce using the vertical hexagonal aeroponics method with the influence of planting direction, sunlight and the addition of liquid organic fertilizer. This research used a factorial Randomized Group Design (RAK) and was repeated three times. The first factor is the Ab mix concentration and the second factor is the planting direction. The lettuce yield variables observed were plant length, number of leaves, harvest yield (root length, wet weight, dry weight) and organoleptic tests. The single factor of adding POC to nutrients influenced the variables wet weight, dry weight and root length, whereas the planting direction treatment only affected root length and the interaction of planting direction treatment and adding POC to nutrients affected organoleptic and stem variables. long. The root length parameters of 58.94 cm, wet weight of 90.59 grams, and dry weight of 8.40 grams are the best parameters if POC is added to nutrition, and treatment of northeastern plantings gives the highest root length, namely 68.73 cm.
