Abstract

State Defense is not only related to national defense and security, but can also be applied in tourism development to preserve nature, maintain local culture, and strengthen the sense of nationality of the community. Sleman Regency of Yogyakarta is one of the regencies that conducts sustainable tourism development by applying the principles and values of State Defense as a foundation in its development. With a diverse social structure of economic, ethnic, and religious levels, the diverse community members can synergize with the government in an effort to develop sustainable tourism in Sleman Regency. On that basis, the purpose of this research is to explain what causes the diverse communities to synergize in developing sustainable tourism. To answer the problem, this research uses a state defense approach in its analysis, using descriptive qualitative research methods and data collection using library methods. The findings of this research are that the community can work together and at the same time can support local government programs in developing sustainable tourism because tourism development in Sleman Regency is based on the principles and values of state defense, so that its people prioritize a strong tolerant life, even though they are diverse in their ethnicity and religion. The conclusion is that the development of sustainable tourism based on the principles and basic values of State Defense can provide economic benefits for the community, preserve nature and local culture, and increase the awareness and sense of nationality of the community.

Abstract

Water hyacinth is an aquatic plant considered as a pest and difficult to eradicate due to its fast growth and strong resilience. However, water hyacinth also contains high fiber content, and the ash resulting from its combustion contains silica that can be used as a concrete additive. This research aims to evaluate the influence of adding water hyacinth ash on the mechanical properties of self-compacting concrete (SCC), such as compressive strength, flexural strength, and split tensile strength. Concrete is a commonly used structural material in various construction projects, and SCC is an innovative type of concrete that can self-compact without the need for a vibrating tool. In this study, data collection was conducted through literature review from various sources, including journals, theses, books, and the internet. Additionally, laboratory testing was performed to examine the coarse and fine aggregates and determine the effects of water hyacinth ash addition on compressive strength, flexural strength, split tensile strength, and modulus of elasticity. The research findings indicate that the addition of 5% water hyacinth ash results in a decrease in compressive strength by 2.008 MPa. However, adding 10% water hyacinth ash can increase compressive strength by 1.02 MPa. Split tensile strength also experiences an increase of 0.255 MPa with a 5% addition of water hyacinth ash and an increase of 0.669 MPa with a 10% addition. On the other hand, flexural strength increases by 0.515 MPa with a 5% addition of water hyacinth ash but decreases by 1.006 MPa with a 10% addition.

Abstract

The profession of a doctor with its scientific tools has unique characteristics. This specificity can be seen from the justification given by law, namely from the permissibility of carrying out medical actions on the human body in an effort to maintain and improve health status. Medical actions against the human body such as surgery, transplantation, removal of certain parts of human organs carried out by doctors are not classified as criminal acts. Conversely, if the action is not carried out by a doctor, it will be classified as a crime. The medical profession is positioned as a noble profession (afficium mobile) similar to the advocate profession. This profession has a noble mission to help people who are experiencing difficulties. The purpose of this study was to analyze the legal responsibility of doctors for alleged medical malpractice for surgical procedures based on Law Number 29 of 2004 concerning Medical Practice and procedures for resolving reports of alleged medical malpractice from an internal view of the medical profession. The term malpractice in the health service sector has recently begun to be widely discussed by the public from various parties as a result of the many complaints of cases that are suspected of being malpractice according to the designations and terms in society against the medical profession which is considered to have harmed patients in doctors treating a patient. As for this research, it uses a normative juridical method supported by an approach to events or phenomena that occur in society. The promulgation and enforcement of legal norms on the limits of medical malpractice are best contained in the Law on Medical Practice, which is now in effect in Law Number 29. 2004 concerning the Implementation of Medical Practice and how accountability should be carried out in accordance with positive law in force in Indonesia.

Abstract

Gasoline is one type of fuel oil for two, three, and four wheeled motorized vehicles. Gasoline have two components, n-heptane (C7H16) and isooctane (C8H18). The quality of gasoline can be determined from amount of isooctane or which is also known as the octane number. Octane number is the number represents the volume percent of isooctane in gasoline. An octane number of 100 means that the gasoline is equivalent to pure isooctane in terms of combustion properties. While the octane number 0 means that the gasoline is equivalent to pure n-heptane. Octane number 92 means that the gasoline consists of 92% isooctane and 8% n-heptane. Nowdays, gasoline has appeared with various and higher octane numbers. The higher the number octane, the more efficient the process of burning the gasoline and selection of the wrong type of fuel oil can affect engine performance. For determine the performance, fuel conumption, on a vehicle, fuel testing is carried out on the Honda GX 160 engine to compare the results of fuel performance Pertalite (90), Pertamax (92), and Pertamax Turbo (98). In this test what will be carried out is to look for the efficiency of each fuel according to the RPM that has been determined, 1800, 2100, 2400, 2700, and 3000. So from each of these RPM you wil see the torque and time of reduced fuel consumption in 8mm tube. From there, you will see the comparison between each fuel, whether it is getting higher and more efficent or not. The increase that occurs in the delta h ratio between pertalite and Pertamax results in an increase of 7% at 2400 rpm, even though the initial torque of Pertalite is higher but the increase in Pertamax remains stable.

Abstract

The fulfillment of consumer rights in the Meikarta land civil dispute is an important issue that requires serious attention. Meikarta is a large property project in Cikarang, West Java, managed by the Lippo Group. However, the project has become controversial due to the civil dispute between the Lippo Group and consumers who have purchased land within the Meikarta project. In this context, the fulfillment of consumer rights is crucial. This research focuses on two main issues, namely: (a) How can the settlement of the Meikarta land civil dispute ensure the fulfillment of consumer rights in District Court Number 162/Pdt.G/2020/PN Ckr? (b) How does the implementation of the Consumer Protection Law ensure the fulfillment of consumer rights in the Meikarta land civil dispute? The research methodology used in this study is a juridical-normative technique, which is essentially a literature review. The research findings indicate that consumer rights were not fulfilled by Meikarta due to delays in the Meikarta development, unclear land status, non-transparent information provided, and inadequate compensation.

Abstract

Along with the development of the times required vehicles that have good performance quality performance. One of them is by improving the quality of combustion that occurs in the combustion chamber. The research method used in this test is to determine the rotation and torque generated from each spark plug. Based on the data obtained, the torque and power generated by iridium spark plugs increases compared to nickel spark plugs, namely at 1800 RPM it produces 15 Nm of torque with 2.826 kW of power to 16 Nm of 3.0144 kW of power. From the test data, iridium spark plugs can increase ∆ BHP by 7%. But not with the specific fuel rate in the combustion engine produced by iridium spark plugs, the best results are higher than the specific fuel rate produced by nickel spark plugs, namely 2.0101 x 10-5 kg/kW.s at 3000 RPM rotation while the results the best specific fuel rate is 1.29 x 10-5 kg/kW.s at 2700 RPM rotation. This means that iridium spark plugs can increase the torque and power of the combustion engine because the combustion that occurs in the combustion chamber is faster so that combustion occurs in a rich state.

Abstract

The millennial generation has taken part as much as 25.87% of Indonesia's population, where this population is included in the productive age category which can be an opportunity to accelerate economic growth. Millennials themselves are a generation that grew up in the industrial era 4.0, where they are known as a generation that is confident, creative, connected to one another, and masters the use of information technology. Compared to generation X, which is a generation that is very adaptive and more focused on results, the millennial generation is a generation that has different characteristics and provisions from other generations. Quality of work life is an employee's perception of a comfortable and pleasant working environment in order to be able to meet employee needs and support employees to work and develop better. There were 45 participants in this study, with the criteria for participants being employees working at PT. X, employees born from 1982 - 2004; employees who have worked for at least one year in the company, and employees with at least high school education. The measuring instrument for this study uses the Walton Model QWL measurement tool, with the addition of two dimensions, namely supervisors, and job characteristics based on (Rostiana & Suyasa, 2014), with a total of 65 questions. The results of the normality test show that the research data is normally distributed, with a high level of quality of work life.
