Perbandingan RAB Rumah Tipe 36 Konsep Konvensional dan Konsep GREENSHIP HOME Berperingkat Gold
Get PDFThis study discusses the comparison of the Cost Budget Plan (RAB) for the construction of a type 36 house with two different concepts, namely the conventional concept and the Gold-rated GREENSHIP Home concept. The conventional concept refers to traditional construction methods with standard materials, while the Gold-rated GREENSHIP Home concept integrates environmentally friendly principles in design and construction, including energy efficiency, use of environmentally friendly materials, and good water management. This study aims to analyze the cost differences between the two concepts and to evaluate the long-term benefits related to energy efficiency and sustainability. The results of the study indicate that although the initial cost of construction with the GREENSHIP concept is higher, energy savings and reduction of environmental impacts in the long term provide significant economic benefits. This study provides important insights for developers and prospective homeowners to consider implementing the GREENSHIP concept in housing development planning
Pengaruh Pencahayaan dan Penghawaan Alami pada Bangunan Sekolah Terhadap Keluhan Sick Building Syndrome bagi Pelajar
Get PDFStudents in Indonesia currently spend up to 8 hours a day in the school environment to attend teaching and learning activities. This time is certainly not a short time especially since most of the activities are carried out in the classroom. This of course can cause boredom and even complaints of Sick Building Syndrome. Some of the causes of Sick Building Syndrome (SBS) are due to the poor quality of lighting and natural ventilation in the building and have not met the requirements of healthy air. School is one of the buildings that need to be considered in a design, especially classrooms for the learning comfort of students who spend most of their time at school. This research uses descriptive-quantitative method by collecting data in the form of observation through observation and distribution of questionnaires and architectural literature used from related sources. The object of this research is SMP Negeri 1 Cilacap School, starting with identifying the characteristics of the subject and the symptoms of Sick Building Syndrome and continuing with the test of the environmental conditions of the learning place by analyzing the size of the room, building orientation, temperature, humidity, wind speed related to natural lighting and ventilation to create a comfortable and adequate learning space for learning. The results showed that the variables of room size, temperature and wind speed were in accordance with the subject data while building orientation and humidity were not in line with the test results of the subjects of each class
Alat Bukti Mata Uang Elektronik Pada Proses Penyidikan Dalam Rangka Pembaharuan Hukum Terhadap Tindak Pidana Pencucian Uang
Get PDFThis study aims to examine the legality and function of electronic currency evidence in Money Laundering Crimes. Existing laws that regulate electronic evidence also do not provide a clear understanding of whether this electronic currency evidence is evidence that can stand alone or is included in electronic evidence that has been previously regulated. The problem is focused on Electronic Currency Evidence which is a new form of evidence whose existence has not been explicitly and clearly regulated in the Criminal Procedure Code, ITE and the Money Laundering Crime Law. In order to approach this problem, a theoretical reference is used from the Legal Certainty Theory. The research method used in this study is normative juridical. Data were collected through literature and field studies, and data collection tools were document studies and interviews and analyzed descriptively qualitatively. The results of the study show that the existence of Electronic Currency has not been explicitly recognized in laws and regulations, although electronic evidence has been recognized in various regulations in Indonesia
Kajian Potensi Komoditi Perkebunan sebagai Bahan Baku Biodiesel untuk Pengembangan Energi Terbarukan: Study of the Potential of Plantation Commodities as Biodiesel Raw Materials for Renewable Energy Development
Get PDFResearch on biodiesel sources from plantation crops such as jatropha, coconut, oil palm, and candlenut has been ongoing in Indonesia since the 1990s. However, many of these studies have been conducted in isolation. Utilizing the PICO framework to analyze diverse studies, researchers identified 13 relevant articles: seven focused on oil palm as a renewable energy source, four on candlenut, and two on jatropha. This distribution indicates that biodiesel research in Indonesia predominantly centers on oil palm, positioning it as the primary focus for renewable energy development. Nevertheless, the high costs and lengthy processes associated with collecting oil palm waste present significant challenges for its practical use in biodiesel production. Interviews with stakeholders from PAG Arun in Lhokseumawe suggest that jatropha may serve as a more viable biodiesel feedstock in Aceh due to its adaptability, ease of cultivation, and lower production costs. Furthermore, as jatropha remains largely underutilized in the region, it offers a promising and more cost-effective alternative for sustainable biodiesel production compared to other crops
Tolerance Analysis Of Several Varieties Cayenne Pepper Under Coconut Tree Shade
Get PDFCayenne pepper is a horticultural crop vital for food seasoning and industrial needs. It is one of the commodities with high economic value. To increase the national production of cayenne pepper, it is necessary to utilize the land's potential to expand planting areas, both as main crops and intercrops. Growing cayenne pepper as an intercrop in coconut plantations is a choice. It has excellent potential for development because cayenne pepper is one type of horticultural crop that is tolerant of shade stress. Coconut plants use only 25% of the available land; about 75% of the coconut plantation area is not used by plants, so it is very likely to plant intercrops. The area of coconut plantations in Indonesia is 3.29 million ha, with 2.47 million ha of intercropped land with the potential to increase production by 20.16 million tons. Bara, Raya, and Genie varieties are shade-tolerant varieties with reduced production ranging from 4.85% to 16.88% and are moderately susceptible varieties with disease severity of 10.62% to 18.82% under shade conditions. The shade-tolerant and shade-pleasing genotypes produced high fruit yield per plant under 50% shade conditions, making them suitable for intercropping or agroforestry systems. These genotypes in the C. frutescens species group are F9.285290-6-10-1-1-1B (G11), F8.285290-290-2-1-2-1 (G12), F8.285290- 290-9-1-4-2-1 (G13), F8.285290-123-6-15-4-1-1 (G15), F7.321290-5-2-2-1-4B (G16), Bonita (G18) while in C. annuum species are F10.145291-10-7-1-1-2- 3-6 (G1), F8.145291-14-9-3-12-1 (G4) and Bara (G8)
Mutualism and Entrepreneurial Coexistence as Catalysts for Family Businesses Sustainability
Get PDFFamily-based companies are the pillars of the economy in many countries, but many fail to survive. Based on the theory of business symbiosis, this study investigates the influence of mutualism and entrepreneurial coexistence on the sustainability of family businesses. The study uses quantitative methods. A total of 210 respondents were selected using convenience non-random sampling techniques. Data were analyzed using a covariance-based structural equation model. The results of hypothesis testing prove that a significant influence exists between variables, and entrepreneurial coexistence partially mediates the influence of mutualism on the sustainability of family businesses. Mutualism fosters a collaborative environment that, in turn, positively impacts family business performance. Establishing clear boundaries between family, ownership, and business matters, encouraging open communication, and promoting professional development among family and non-family personnel are all key elements toward sustaining a successful symbiotic relationship. From a practical standpoint, family enterprises must actively manage the inherent tension between emotional attachment and professionalism. Expanding family-business symbiosis theories show how mutualism and entrepreneurial coexistence maintain advantageous dynamics in family enterprises, improving sustainable family operations. Our research emphasizes the work of the theory of family business symbiosis as an alternate theory for sustaining family enterprise
Determination of Fiscal Dependence and Disaster Risk on Local Government Unexpected Expenditure Allocation in Indonesia
Get PDFIndonesia's vulnerability to natural disasters significantly challenges local government fiscal management and disaster preparedness. This study examines the relationship between budgetary dependence and disaster risk index on the allocation of contingency expenditures (BTT) in local governments in Indonesia. This study analyzes how fiscal dependence and regional disaster risk index affect local government decisions in preparing resources to anticipate emergencies. This research is academically relevant because of the limited studies linking fiscal governance and disaster risk in developing countries, particularly Indonesia. The study uses a quantitative approach with correlation analysis of regency/city government budget data throughout Indonesia in 2023. The study's results show that the level of fiscal dependence or the disaster risk index does not entirely determine the allocation of BTT by local governments. Although there is a significant negative correlation between disaster risk scores and unexpected spending allocations, the relationship is weak. This indicates that other factors play a greater role in BTT budgeting decisions. In the context of policy, the results of the study recommend the development of regulations that encourage local governments to allocate unexpected spending budgets proportionally according to the level of risk faced, so that regional fiscal readiness in dealing with emergencies can be more optimal. Academically, this study enriches the literature on fiscal governance in developing countries by including disaster risk variables as an essential factor in regional budgeting
