The Effect of Illuminance Artificial Light Interior on Color Difference Identification in People with Colour Vision Deficiency (CVD)

Individuals with color vision deficiency (CVD) face challenges in various daily activities that require color identification such as selecting appropriate clothing combinations, identifying ripe fruits or vegetables, et cetera. This study aims to identify the best illuminance artificial lighting for color difference identification among individuals with CVD in Indonesia (0,7%). The research focuses on the quantitative analysis of experimental data to assess the effect of different types of illuminance artificial lighting on color perception in participant with CVD. A controlled experiment was conducted with a sample of individuals diagnosed with CVD (Deutronomali, Deutronopia, and Protonopia), utilizing a standardized color difference identification test based on Natural Color system (NCS) as the color experiment tools. The participant was exposed to different artificial lighting conditions, including various intensities (illuminance) and different color background (black or white) for each category. Quantitative data is collected, focusing on the accuracy, speed, and total steps for completing the task under different artificial illuminance conditions. Statistical analysis, including analyses of variance (ANOVA) and correlation analyses, are conducted to examine the relationship between illuminance lightings and color difference identification in individual with CVD. The results based on the analysis of duration, number of steps, and accuracy, the optimal illuminance level for identification color differences falls within the range 400-500 lux. The second-best illuminance level falls within the range 300-400 lux. In conclusion, range 300-500 lux are the best illuminance level for perceiving color variation.

Islamic Moderate Values in Teaching Classic Islamic Books at Modern Islamic Boarding Schools in Indonesia

This study discusses Islamic moderation in learning classic Islamic books at modern Islamic boarding schools in Indonesia. This study aimed to examine the application of Islamic moderation in learning classics and the supporting factors for the successful application of religious moderation in learning classics at the Islamic Boarding School of Modern al-IstiqamahNgatabaru Indonesia. This study used qualitative methods, and data collection techniques were carried out through direct observation, in-depth interviews, and written document analysis. The results of this study indicate that there are three indicators in the application of Islamic moderation in learning the ‘yellow book,’ namely the application of moderation in the learning process, the application of moderation in the form of understanding, and the application of moderation in the form of practice in worship. The supporting factors for Islamic moderation in learning the ‘yellow book’ are, Islamic boarding schools are not tied to one school of thought, ustad provides the broadest possible understanding to students, ustad does not indoctrinate students to follow one school of thought, ustad is not allowed to justify one school and blames on the other hand, students are free to choose the schools they believe in strongly. While the inhibiting factors are the limited practice of santri worship, senior santri are not allowed to influence junior santri, and learning the ‘yellow book’ is still limited. The implications of Islamic moderation in understanding the ‘yellow book’ at the Modern al-IstiqamahNgatabaru Islamic Boarding School are elastic and flexible, tolerant, not categorized, and not confused in making choices. Many alums are in different Islamic mass organizations, and alums join student organizations that are diverse, and active in religious activities in the community.

E-Commerce Product Demand Modelling Using Machine Learning Algorithm Case Study of Rice Trading Products in PT XYZ

E-commerce XYZ is an Indonesian commerce company that have 3 types of products in its B2C business line: trading, consignment, and marketplace. From January 2021 until October 2022, the company’s trading rice category product sales generated a negative profit. Even though for the last several years e-commerce has been focused on growth instead of profitability, the current economic environment is forcing e-commerce companies to focus on profitability as well. For trading products, maximum profit can be achieved in two ways: selling products with a very high margin but with less quantities or selling in large quantities but with a sub-optimal margin. Hence, the company needs to find a demand function model that can be used to generate maximum profit. To find the best model, the researcher first created a baseline model by using median for every product group which is already grouped based on their Unit of Measurement. Next, to find the best model, the researcher will create a demand function using 4 other models. It is found that Gradient Boosted is the best algorithm to model the demand function. Although this model successfully models a demand function for a product category in e-commerce, business context still needs to be added before this model can be implemented in real life as well as finding other features that might affect the demand function.

The Effect of Shade and NPK Fertilization on Growth and Yield of Asystasia gangetica as a Forage

Asystasia gangetica is a weed usually found in oil palm plantations, which is used as a source of forage and cultivated at a known effective shade level and optimal fertilizer dosage. Therefore, this study was carried out at a place without shade (NS) and 75% of shading net (S) at the Experimental Field of the Faculty of Agriculture, Universitas Mulawarman, Samarinda, Indonesia. The seedlings used were planted and fertilized with NPK at doses of 0 g, 1.6 g, and 3.2 g per polybag. The results showed that the level of shade affected plant height, several branches, yield of dry matter shoot, the content of chlorophyll a, b, and a/b content, CP, CF, EE, NFE, and ash, but not on chlorophyll a+b. The dosage of NPK fertilizer affected plant height, the number of branches, yield of dry matter, chlorophyll a, b, and a+b content, CP, CF, EE, NFE, and ash content, while chlorophyll a/b ratio was not influenced. The interaction between shade level and NPK fertilizer dose only occurred in the number of branches, chlorophyll a, b, and b+c content, CP, CF, EE, and ash content, but not on chlorophyll a/b ratio and NFE content. The flowering rate was faster in NS plants, where those with NPK fertilizer dose of 0.32 g/polybag gave the highest yield, except for CP and ash content which had the highest yields on S plants with 0.32 g NPK/polybag.

Highways the Death Door of Wild Life: A Comprehensive Study in Indian Thar Desert

Highways play a crucial role in economic development of any country. Besides this, highways are also one of the causal agents of wild life destruction. The present investigation was based on the study of mortality rate in some selected wild animal groups in road accidents viz., Mammals, Birds and Reptiles on the national and state highways passing through the Indian Thar Desert, and the survey of biodiversity of roadside fauna and flora. The survey was also focused on the effects of highways on the population density and biodiversity of the area. Among the selected animal groups Mongoose, Squirrel, Wild Boar, Hedgehog, Chinkara, Desert fox, Nilgai, Greater Coucal (Crow Pheasant), Sparrow, Partridge, Babbler, White eared and Red Vented Bulbul, Peacock, Desert Monitor, Garden Lizzard, Skinks, Cobra, Vipers etc. were found killed in the road accidents. Maximum mortality rate in the road accidents during the survey was observed in Mongoose, Greater Coucal and Desert monitor (Varanus) throughout the study period. It was experienced that unavailability of safe passes across the highways, negligence driving and over speed of the vehicles were the major causes of wild life destruction on the highways.  Maximum mortality rate of wild animals was found in July to November in each calendar year and minimum was during the month December to February. By the present investigation it was suggested that making transverse tunnels across the highways at regular interval, warning signboards about the wild life abundance regions, awareness among the drivers for wildlife protection and covering the road sides with net fencing in wild life abundant areas may reduce some degree of wildlife destruction in road accidents.
