Abstract To some people, back-in parking maneuver is a relatively hard thing to do. However, previous studies have proven that back-in parking is safer than head-in parking because when exiting the parking space (back-out) from head-in parking, the driver's field of view is more limited, thus increasing the chance of an accident. This study aims to determine the changes in the driver's viewing frequency on the rear-view mirror, maneuver duration, and degree of difficulty during back-in parking maneuvers. Data collection was obtained from 45 participants who tried to park their cars in a parking space with an angle of 30°, 45°, 60°, 90°, each with four different conditions of parking spaces. The driver’s viewing frequency on each rear-view mirror (left, right and center) and maneuver duration were obtained from a dashcam and an external camera recording. The difficulty level for maneuvering was filed according to the driver’s opinion during the experiment for each parking space condition. Based on the data analysis, it was proven that the existence of cars parked on either side of that parking space (obstacles), parking space line signs, and both simultaneously increase the driver’s viewing frequency and maneuver duration when doing back-in parking maneuver, but at the same time, ease the parking maneuver, according to the driver.

Andrew Bruce’s path to building a digital business offers a map of hazards for those selling digital services to oil companies. When he started Data Gumbo, he was thinking about building a business aimed at solving the data quality issues that were a constant headache when he was working on developing digital control systems at NOV. One option was a fee-for-service business that cleaned up drilling data. While he knew that would make the engineers happy, he wondered if accountants would notice. Clean data ultimately can have a large financial impact by facilitating the digital transformation. But, for those doing financial statements, it is easy to miss because it does not have a direct impact on the bottom line, even though it can facilitate digital changes that do. As he searched for a better idea, he began thinking about building around a blockchain network. At the time, blockchain was only associated with keeping a record of virtual currency ownership. But he could see uses for an immutable record of contracts and transactions in the drilling business, where contract disputes, audits, and wrangling over bills are costly, time-consuming rituals. The plans required only specific bits of operational data, such as the volume of product loaded or the time of delivery, to measure performance based on the contract terms. Building a service that minimizes the customer data needed removed a potential sticking point in negotiations. Years passed as he worked to find users willing to work together to create a blockchain network to see if multiple companies could make this idea work in an oil field. Another thing that kills many startups is time. Investments by the venture arms of Equinor and Saudi Aramco gave Data Gumbo the cash to slowly recruit buyers and sellers to create and test whether the network he envisioned, known as GumboNet, actually could deliver on its promise of faster, argument-free billing that saved money. The most public example was the result of a test by a multicompany consortium in 2019 that showed a paperless system for tracking water or any other oilfield commodity can work accurately and deliver results efficiently. That was the prelude to more testing, until the oil price crash forced the industry to accelerate its search for ways to lower the cost of producing a barrel of oil. The crash sped the transition from testing to field uses and helped expand the company’s customer base. Data Gumbo has added locations in the Middle East and South America. One downside of success: It offers a model for potential competitors. “It is always a concern. It would be naive to say it is not. Anyone can use blockchain tomorrow,” Bruce said. What is harder to do is build a network of users, such as GumboNet. Assembling a group of users who understand the rules and trust the system—like a large group of merchants willing to accept a particular credit card—is a hard thing to replicate. To strengthen those ties, Bruce continues to look for new ways to generate value for users. One idea that he said is on the way this year is a service that uses data associated with logistics contracts, such as water truck traffic data, to generate emissions or water use data to help answer tough questions raised by investors requiring environment, safety, and governance reports.

Being a college president is hard enough, but when you add to it a crisis, it makes the task of leading even more of a challenge. Whether that crisis is isolated like Virginia Tech, regional with situations like hurricanes and natural disasters (Hurricane Katrina, Hurricane Harvey, wildfires, tornadoes), or now a national issue with the coronavirus (COVID-19), leadership has definitely been a hard thing to do. For the first time in history, we are all dealing with the same situation at the same time. While there is research about leading during a crisis, this new pandemic is unprecedented. The purpose of this research is to gather a perspective from college and university presidents in working through this. This will add to the literature on crisis leadership, and how some current college presidents are addressing this issue. Public and private 2-year and 4-year college/university presidents/chancellors were interviewed about their thoughts on this topic. What is gleaned from this information will add to the leadership information in dealing with the “new normal.”

Extracurricular activities are student activities that include reasoning and science, interests and hobbies, efforts to improve student welfare and social service for the community. In this regard, STDI Imam Syafi'i Jember participated in developing the interests and talents and potential of students to be able to compete in the era of globalization. One of the student activity units formed was the Research Rijal Student Activity Unit. Research on this UKM is needed. The reason is because the making of scientific papers that are the product of this unit is a hard thing for students in general.This study aims to explain the cause of students lack of interest in making scientific papers, factors driving students to join Research Rijal UKM, and the contribution of these UKM in improving scientific writing. This research uses a qualitative approach with the type of case study. Data is described descriptively. The analysis used is inductive analysis. Based on its scope, this study takes one site. Data was collected from several documents, observations, and interviews with 17 informants. The main informants in this study were 13 students of the Hadith Sciences Study Program. Then supplemented with additional informants from 3 Ahwal Syakhsiyah Study Program students and P3M supervisors.This research produces several conclusions. First, that the cause of students' lack of interest in making scientific papers is because: (a) students are less interested in writing, (b) lack of ideas and ideas, and (c) the rules for writing scientific papers that are relatively complicated. Second, the factors driving the students of the Hadith Science Study Program to join Research Rijal UKM include: (a) they want to learn the methodology of writing scientific papers, (b) foster interest in reading, (c) practice critical habits of scientific papers, and (d ) develop general writing skills. Third, the contribution of UKM Rijal Research includes (a) giving special lectures to UKM members on how to make good scientific journals and (b) providing further guidance in the completion of scientific papers.

A Long, lonely journey, with sadness in the heart; away from the familiar to the strange: that is a hard and dreary thing even to the rich, the strong, the instructed: a hard thing, even when we are called by duty, not urged...
