Candlenut shell is an organic waste that has a hard texture and has a high carbon element. The amount of candlenut shell produced from each processing of candlenut seeds is very large but has not been optimally utilized. For this reason, an effort is needed to utilize candlenut shells so that they do not become waste. In the manufacture of hazelnut shell briquettes, hazelnut shells are carbonized at 500 °, sifted with mesh 30 and 100 sieves, given a compressive load of 3 kg, 4 kg, 5 kg and 5.5 kg, the adhesive on hazelnut shell briquettes is starch and drying is carried out with a drying oven for 3 hours at a temperature of 80 °. The purpose of this study was to determine the effect of variations in pressure and particle size on the quality of hazelnut shell briquettes when viewed from the combustion rate and calorific value. The methodology used in this research is experimentation on hazelnut shell briquettes, testing hazelnut shell briquettes including testing water content, testing ash content, burning rate and calorific value of briquettes. From the results of the research on hazelnut shell briquettes with variations in pressure and mesh, the highest calorific value in hazelnut shell raw material briquettes is in the 5.5 Kg pressure specimen on mesh 30, namely 9855.18 Cal/gram and the bomb calorimeter test results are 7008.03 Cal/gram with an error rate of 24.40%, the higher the pressure will produce a higher calorific value as well. The highest combustion rate value is in hazelnut shell briquettes at a pressure specimen of 3 Kg mesh 100 with a value of 1.2 grams/minute the smaller the particle size, the higher or faster the combustion rate.

This research examines the application of fiqh muamalah in Islamic economic practice by utilizing Corporate Social Responsibility (CSR) funds as a solution to overcome social inequality. This research uses a qualitative approach with a library research method. The main focus of this approach is to understand in depth how the principles of fiqh muamalah are applied in Islamic economic practice, especially in the management of Corporate Social Responsibility (CSR) funds as an effort to realize social justice. This approach was chosen because it is in accordance with the purpose of the study, which emphasizes conceptual and interpretative understanding of literary data. Thus, CSR functions as a manifestation of corporate social responsibility, as well as a means of da'wah bil hal that spreads benefits widely and reflects the principle of rahmatan lil 'alamin. This application is also in line with DSN-MUI fatwa No. 77/DSN-MUI/VII/2010, which emphasizes the importance of CSR management according to sharia principles. Fatwa DSN-MUI No. 77/DSN-MUI/VII/2010 provides guidance on the implementation of CSR in accordance with sharia, including the management of halal funds, setting clear social goals, and applying the principles of transparency and sustainability. In conclusion, CSR in the view of fiqh muamalah is a very important strategy to create a fair, sustainable and inclusive Islamic economic order. This is particularly relevant in Indonesia, which is a Muslim-majority country.Keywords : fiqih muamalah, ekonomi islam, corporate social responsibility, keadilan sosial

This study aims to determine the effect of product quality, product design and brand image on purchasing decisions of Honda Vario Automatic Motorcycles through word of mouth as an intervening variable in the Special Region of Yogyakarta. The method used in this study is quantitative with Partial Least Square (PLS) analysis. Data were collected through questionnaires distributed to respondents who are consumers of Honda Vario Automatic Motorcycles in the Special Region of Yogyakarta. The sampling technique used was Purposive Sampling, with a total of 100 respondents. Data processing using SmartPLS 4 with the conclusion that product quality and product design do not have a positive effect on purchasing decisions or word of mouth. Conversely, word of mouth has a positive effect on purchasing decisions. Brand image has a positive and significant effect on purchasing decisions and word of mouth. In addition, word of mouth is only able to mediate the influence of brand image on purchasing decisions, but cannot mediate the influence of product quality and product design on purchasing decisions.

Micro, Small, and Medium Enterprises (MSMEs) are an important part of the Indonesian economy, but many MSMEs still have difficulty using technology and transforming into sharia-based businesses. This study aims to analyze how technological innovation, especially e-commerce, can help MSMEs adapt to sharia business principles. Using a qualitative approach and literature study, this study examines the literature on sharia e-commerce, digital innovation, and the development of MSMEs in the digital era. The results show that e-commerce has great potential to expand the market, increase efficiency, and support sharia transactions such as interest-free financing. In addition, cooperation between digital platforms and sharia financial institutions can strengthen the halal economy. However, challenges such as low digital literacy, lack of infrastructure, and competition from large companies still exist. Therefore, it is important for all parties to cooperate to encourage the digitalization of MSMEs in an inclusive manner and in accordance with Islamic values. Keywords : MSMEs, e-commerce, technology innovation, sharia business, digital transformation.

One of the reasons the Sugar Factory failed to meet its sugar production target was due to damage to the machine components, particularly at the milling station, where the milling rollers are located. The milling rollers play a crucial role in extracting juice from sugar cane, separating the juice from the bagasse, and measuring the raw juice before it enters the purification process. This unit is designed to maximize raw juice yield while minimizing the amount of bagasse. The milling rollers are arranged in a triangular configuration of three mills, with a milling path between the front and rear rollers that can move forward and backward. Several common issues affect the milling rollers, including surface wear, damage from excessive loads, and wear from repeated friction between the rollers and the sugar cane. Sugar cane itself contributes to roller wear due to its composition, which includes water, sucrose, cellulose, lignin, hemicellulose, ash, and silica. These substances are highly corrosive, even to stainless steel, and act like abrasives against the rollers. The usual remedy at the factory is to weld stainless steel onto cast iron rollers. However, this method has only been moderately effective, as the rollers continue to experience wear after a short period. Based on field observations and literature reviews, some suggested solutions include more frequent cleaning and applying a tungsten coating to the roller surfaces.

The current fuel is still sourced from fossil fuels, namely oil, coal and The current fuel is still sourced from fossil fuels, namely oil, coal and gas, which have many impacts on the environment. As an agricultural country located in the tropics, Indonesia is rich in biomass energy sources. In this research, the use of candlenut shells will be used or processed into alternative fuel, namely briquettes, with the aim of determining the value of combustion time and temperature produced through variations in composition and mesh size. The results of the research show that the effect of the burning temperature has an impact on the burning time of the briquettes and the resulting temperature, where the best burning time and temperature values ??of the briquettes are produced by a burning temperature of 400°C with a grain size of 100 mesh, namely 177 minutes with an average burning temperature briquettes 193.9°C.
