The micro, small and medium enterprises sector has a major contribution to economic development in Indonesia. One of the micro, small, and medium enterprises (UMKM) is the SMG Mulya Factory, which produces snacks, and complimentary crackers. The work area certainly has risks and hazards that may arise. The reason makes MSME owners implement occupational safety and health for both owners and workers. This study aims to identify the application and understanding of occupational health and safety at the SMG Mulya Factory. This research uses the hazard and operability study (HAZOP) method. The results showed that the potential for extreme work hazards was 8.33%, high and medium risk hazards were 25%, and low risk was 41.83%. There is an extreme risk when frying crackers is not accompanied by personal protective equipment (PPE), so it is feared that it will be splashed by heat from the oil used when frying. There is a high risk when the dough-making machine does not use a lid, so it is feared that when washing the tool, there will be puddles of water on the floor so that it is slippery and causes injuries to workers. Sektor usaha mikro, kecil dan menengah memiliki kontribusi yang besar dalam pembangunan ekonomi di Indonesia. Salah satu pengembangan Unit Usaha Mikro kecil dan Menengah (UMKM) adalah adanya Pabrik SMG Mulya yang memproduksi krupuk yang notabenenya adalah makanan ringan, cemilan dan pelengkap. Area kerja tentunya memiliki resiko dan bahaya yang dimungkinkan muncul. Hal tersebut membuat pemilik UMKM menerapkan adanya keselamatan dan kesehatan kerja baik bagi pemilik maupun bagi pekerja. Penelitian ini bertujuan untuk mengidentifikasi penerapan dan pemahaman kesehatan dan keselamatan kerja pada Pabrik SMG Mulya. Penelitian ini menggunakan metode hazard and operability study (HAZOP). Hasil penelitian dapat menunjukkan bahwa potensi bahaya kerja ekstrim sebesar 8,33%, potensi bahaya risiko tinggi dan sedang sebesar 25% dan risiko rendah sebesar 41,83%. Resiko ekstrim terdapat pada saat penggorengan krupuk tidak disertai penggunaan alat pelindung diri (APD) sehingga dikhawatirkan terkena cipratan panas dari minyak yang digunakan saat penggorengan. Resiko tinggi terdapat pada saat pembuatan adonan mesin tidak menggunakan tutup sehingga dikhawatirkan ketika mencuci alat tersebut menjadikan adanya genangan air pada lantai sehingga licin dan mengakibatkan luka pada pekerja.

Currently, the consumer goods business in Indonesia is very strict, including for sugar products. Until now, sugar products cannot be fully replaced by other products. The purpose of this study was to determine the effect of customer satisfaction and brand equity on the interest in repurchasing sugar products. This study used a descriptive analytic method using two data sources, namely primary data and secondary data. Primary data obtained by interviewing consumers who consume sugar as many as 60 people. Secondary data obtained from data sourced on the internet, books, journals and other sources deemed relevant. Analysis of the data used in this study is multiple linear regression with the dependent variable repurchase interest and two independent variables, namely customer satisfaction and brand equity. Based on the research results, it is known that the significance value of the F test is 0.000 so that the value is less than 5% alpha. Thus it can be said together that the variables of customer satisfaction and brand equity have an effect on the interest in repurchasing sugar. Based on the results of the t-test, it can be seen that the variable X1 (customer satisfaction) has a significance value of 0.0007 so that the value is less than alpha 0.05 in other words that the variable X1 (customer satisfaction) affects the interest in repurchasing. Variable X2 (brand equity) has a significance value of 0.0317 so that the value is less than alpha 0.05, in other words that the X2 variable (brand equity) affects the dependent variable repurchase interest.

Metode analisis yang digunakan dalam penelitian ini adalah analisis regresi linear berganda. Dari hasil penelitian diperoleh hasil bahwa secara parsial ROA tidak berpengaruh terhadap nilai perusahaan dikarenakan nilai signifikansinya di atas 0,05 yaitu sebesar 0,06. Secara parsial investment opportunity set memiliki pengaruh terhadap nilain perusahaan karena nilai signifikansinya di bawah 0,05 yaitu sebesar 0,00. Koefisien regresi dari investment opportunity set adalah sebesar 0,522 sehingga bersifat positif. Artinya setiap kenaikan investment opportunity set sebesar satu satuan maka akan diikuti kenaikan nilai perusahaan sebesar 0,522 satuan. Secara simultan Return on Asset dan -investment opportunity set berpengaruh secara bersama-sama terhadap nilai perusahaan. Persamaan regresi yang terbentuk adalah NP = 0,196 + 4,38ROA + 0,522IOS + e.

The economy of a country is basically supported by many sectors, one of which is the automotive industry sector with the designation as a provider of transportation facilities. The policy regarding transportation facilities is supported by the ministry of industry which issued a policy on environmentally friendly cars or low cost green cars (LCGC). Apart from being environmentally friendly, the car also has an affordable price in the community. Forecasting sales of LCGC cars is important for many companies that use past sales data to predict the amount of production that must be done so that goods continue to sell according to company targets. This will have an impact on the life and death of the automotive industry sector in the region. Important forecasting is done by many companies that use past sales data to predict the amount of production that must be done so that goods continue to sell according to the company's target. The data used in this research is secondary data. The secondary data needed in this study is the data on LCGC car sales in Indonesia from December 2019 to November 2020 obtained from secondary data sources. The data analysis method used in this research is exponential smoothing and trend analysis using POM QM software for Windows. The results also show that a good method to use as a sales forecasting method is the exponential smoothing method. This is because this method has a smaller MAPE value than the MAPE value in the trend analysis method. The MAPE figure for exponential smoothing is 4.9%, while the MAPE figure on the trend analysis method is 6.69%. In the exponential smoothing method, it is predicted that the sales of LCGC type cars in the next period are approximately 8448 units, while according to the trend analysis method, the sales forecast for the next period is 3894 units.

Tourism is a sector that is currently a priority for the current government. This is not something that is surprising, because Indonesia has thousands of tourist destinations. The types are also very diverse according to the natural, cultural and historical riches in Indonesia which are unique to each. The government is targeting tourism as the largest contributor to foreign exchange. D.I Yogyakarta itself has a tourist attraction that will not disappoint visitors. The designation of Yogyakarta as a tourism area illustrates the potential of this province in a tourism perspective. Various types of tourism objects have been developed in this area, such as nature tourism, historical tourism, cultural tourism, educational tourism, and shopping tourism. One of the tourist sites in D.I Yogyakarta that must be visited is the Nglanggeran Ancient Volcano. This tourist location has received many awards so it is indeed worth a visit. This study aims to determine what factors influence the revisit intentions of tourists to the Gunung Api Purba Nglanggeran. This study uses primary data and secondary data. Primary data is obtained by using direct interviews with tourists who have come to Gunung Api Purba Nglanggeran at least twice. Secondary data is used to strengthen primary data. Secondary data were obtained from relevant sources such as books and journals. This study used a sample of 60 people. The data analysis method used in this study is multiple linear regression analysis. There are three independent variables used in this study, namely attractiveness, service quality and facility, while the dependent variable used in this study is revisit intentions. Based on the results of research using the F-test, it can be concluded that the independent variables of attractiveness, service quality and facility together have an effect on the dependent variable revisit intentions. Based on the results of the research that has been done, it can be seen that there are two variables that affect revisit intentions in Gunug Api Purba Nglanggeran, namely the attractiveness and service quality variables, while there is one variable that has no effect, namely facilities. The attractiveness variable has a t test significance value of 0.0178 while the service quality variable has a t test significance value of 0.0001. The meaning of these two values means that both of them are less than the alpha value of 5% so that both variables are significant. If you look at the value of the regression coefficient on the attractiveness and service quality variables, it is positive so that the increase in the value of both will increase the interest in returning to Gunung Api Purba Nglanggeran
