Abstract

Secara global di seluruh dunia, Demam Berdarah Dengue (DBD) telah tumbuh dengan cepat dalam beberapa dekade terakhir.Di Indonesia sendiri, angka penderita penyakit DBD ini sendiri masih tergolong tinggi tiap tahunnya dan hal ini juga terjadi di Jawa Timur. Pada penelitian ini akan diselidiki faktor-faktor yang mempengaruhi persentase kematian pada penderita DBD di Jawa Timur dengan menggunakan analisis regresi Spline. Dari hasil analisis didapatkan bahwa model Spline linier dengan 1 titik knot merupakan model terbaik daripada model spline linier dengan 2 dan 3 titik knot berdasarkan Generalized Cross Validation (GCV) minimum dengan dengan R-Sq sebesar  91.62% dan nilai MSE adalah 0.1823. Variabel-variabel yang signifikan berpengaruh terhadap presentase kematian penderita DBD adalah persentase sarana kesehatan, persentase tenaga kesehatan, rata-rata usia perkawinan pertama, persentase daerah yang berstatus desa, rata-rata lama pemberian ASI eksklusif, persentase penduduk miskin, rata-rata curah hujan, persentase penduduk wanita dibanding total, rata-rata lama sekolah penduduk umur 15 tahun ke atas, angka bebas jentik.

Abstract

One of the models time series which also involves spatial aspects (spatio-temporal) is Generalized Space Time Autoregressive (GSTAR). Until now, GSTAR modelling don’t involve metric-type, which is called GSTARX. Parameter estimation for spatio temporal modeling is still limited by using Ordinary Least Square (OLS) which is less efficient because the residuals are correlated. Generalized Least Square (GLS) is one of the alternative methods for parameter estimation residuals are correlated. In this study would like to looking at the efficiency of GLS estimation method is compared with OLS to correlated data in GSTARX model. Simulation results show that the estimation GLS method is more efficient than using OLS if residual correlated.

Abstract

Companies in general have their own characteristics, including those listed on the Jakarta Islamic Index (JII). Companies that enter the JII calculation are motivated by the criteria set by the MUI DSN as a condition for the company's entry into JII. Based on this, there are two problems that become the main study in this research, namely: first, is there an effect of Company Size, Profitability and Leverage on the Corporate Social Responsibility Disclosure in companies listed in JII: second, which one has more dominant influence between company size, profitability , and Leverage on Corporate Social Responsibility Disclosure at companies registered with JII. This study uses a quantitative approach. Sources of data obtained by using secondary data using the financial statements of companies listed in the Jakarta Islamic Index. The results of this study indicate that company size does not have an influence on corporate social responsibility because basically companies that have a large-scale disclosure of their corporate social responsibility are getting wider. In addition, ROA has a significant negative effect on Corporate Social Responsibility in the Jakarta Islamic Index company. And also, DER does not have a significant effect on the Corporate Social Responsibility Disclosure of companies listed in JII.

Abstract

Pamekasan is the largest batik-producing district in Madura. There are around 28 batik centers spread across several sub-districts, and the most are in the Proppo sub-district, namely 12 batik centers. One of these batik centers is Klampar Village. Product penetration into the market has also been quite slow because the availability of information about Pamekasan batik has not been widely exposed. Therefore, it is necessary to increase promotion and sales using digital marketing.

This type of research is descriptive qualitative research. The result of this activity is that participants are trained to utilize social media to optimize marketing via the internet. Participants are guided by a resource person. And at the end of the activity, an evaluation is carried out to see how big the impact is on digital marketing through social media.

Proper and effective human resource management can enhance employee performance and enable the achievement of company goals. This research aims to determine the influence of the work environment and work motivation on employee performance at BMT NU Jatim in the Pamekasan Regency. The research methodology employs a quantitative approach with a population of 58 individuals, and a saturated sampling technique is used to select the sample. The primary data used in this study are collected through questionnaires. The data analysis technique employed is multiple linear regression analysis. The analysis results indicate that the work environment has a positive and significant impact on employee performance, as does work motivation.

Data collection was carried out through surveys using questionnaires, which also involved observation techniques and interviews as support. The results of the research show that the people of Sumenep obtained a perfect social piety index score (with a cumulative score of 83.36), including aspects of the social stability index of 84.71 (very good), the social solidarity index of 78.01 (good), and cooperation index 87.35 (very good). The achievement of the social piety index with a value of 83.36 in the very good category shows that the people of Sumenep have achieved a very good level of social harmonization.

Abstract

Klampar Village in Pamekasan Regency has great potential in the batik industry, with the largest proportion of batik makers in the region. Batik making is the main activity and attraction for tourists. The uniqueness of Klampar batik lies in its richness of colors, with more than three colors in one cloth, including dark brown, black, red and green, which makes it superior to other batik centers. Some batik artisans already have their own UD/CV, showing promising economic potential. The village also has stable internet access, which opens up opportunities for effective digital marketing. The objective of this community service activity is to build the capacity of batik artisans in Klampar Village to use TikTok social media and WhatsApp Business to increase sales of their batik products.

Abstract

The forecast is more accurate when involving an exogen, for example, the generalized spatio temporal autoregressive (GSTAR) model with exogenous variables (GSTARX). This study aims to obtain appropriate statistical values to identify autoregressive orders for time dependencies and order effects with exogenous variables such as Eid al-Fitr and the consumer price index (CPI) in the GSTARX model. Additionally, this study seeks to obtain a GSTARX model suitable for forecasting. The case study is the inflows and outflows in four locations in East Java. The simulation results show that the statistical values for identifying VAR order for time dependencies use the matrix partial cross-correlation function (MPCCF). Meanwhile, effect orders from exogenous variables in the two-level GSTARX model show CCF at level one. In addition, GLS (general least squares) produces a more efficient estimator than the OLS (ordinary least squares). The results of the case study show that the two-level GSTAR model forming inflow and outflow data are GSTARX (31) and GSTARX ([1,3]1) respectively. In addition, the comparison of forecast accuracy shows that, in general, the smallest root mean square error (RMSE) value in the two-level GSTARX model is the inverse distance weight.
