Abstract

Para mahasiswa mencoba mencari kegiatan yang sifatnya dilakukan bersama antara beberapa denominasi gereja dan memberikan manfaat secara langsung bagi lingkungan gereja dan masyarakat umum di kemudian hari. Dari hasil diskusi, akhirnya para mahasiswa memutuskan untuk membuat kegiatan workshop menjahit di kalangan kaum wanita di lingkungan PGIS kota Cirebon. Kota Cirebon adalah kota penghasil kain batik, salah satu yang menjadi ikon dan banyak dikenal oleh masyarakat adalah batik motif “mega mendung”. Batik ini bila di bila dijual langsung, harganya menjadi murah dan minatnya juga terbatas kalau dijual dalam bentuk kain. Bila dijual dalam bentuk produk jadi fashion (baju, celana, asesoris seperti tas, dompet, topi) akan sangat mungkin diminati oleh banyak orang dan tentunya ada nilai tambah di harga jual.

Abstract

The problem in this research is the lack of research that shows traditional musical instruments in Central Kalimantan in the form of visualization (images) and elaboration with culture, maintenance space and also religion, which is basically applicable and useful for the maintenance of property, culture, philosophical values contained therein. This research method is qualitative research with data search through visualization of images or camera shots of the authors directly to the source of traditional musical instruments in Palangka Raya. The results show that diversity, Indonesianness through gotong royong, instrument maintenance, culture and religion are inextricably intertwined as a space for diversity and religiosity and at the same time as a further elaborative space to explore musical instruments with something that enriches art.

Abstract

One of the manufacturing companies engaged in agribusiness, one of which is processing cooking oil, often occurs damage to goods due to excess stock of goods and increases expenses for storage costs. Before carrying out the production process, the company must forecast demand to find out how much the estimated raw material needs will be used as inventory control so that there is no excess or shortage of stock that will harm the company. The purpose of this study is to predict the amount of cooking oil demand in the next 12 periods, plan the lot size of raw materials with the lowest cost and determine the right time to order raw material supplies. The method used in forecasting is Autoregressive Integrated Moving Average (ARIMA) and lot size planning with Materials Requirements Planning (MRP) FOQ and POQ techniques. ARIMA forecasting results with a MAPE value of 33% and the lowest cost technique chosen by POQ

Abstract

This research examines the factors affecting the firm value of non-financial companies in Indonesia. The independent variables in this study are dividend policy, profitability, firm size, leverage, firm growth, liquidity, and audit committee, while the dependent variable is firm value. This study uses data from non-financial companies listed on the Indonesia Stock Exchange (IDX) from 2017 to 2020. The sample data were tested using a multiple regression model, and the sample selection process used a purposive sampling technique so that a sample of 78 companies was obtained from a sample of 312 data. The results of this study indicate that the variables of profitability, firm size, and leverage positively affect firm value; the dividend policy, firm growth, and audit committee variables hurt firm value, while liquidity variables do not affect firm value.

Abstract

SARS-CoV-2 (COVID-19) virus spread quickly worldwide affects a variety of industries. The government took preventive steps to control the infection, such as diagnosing the human's lung by taking an X-Ray to see if the lungs were infected with COVID-19 or not. Using several pre-trained Convolutional Neural Network models as the basic model, this research deconstructs the comparison of fine-tuned architecture to identify which pre-trained model delivers the best outcomes in diagnosis by applying machine learning. Comparison is conducted using two scenarios that use batch sizes 64 and 32. Accuracy and f1 score are two evaluation metrics used to justify the model's good performance because the images in the real world, especially for positive classes, are scarce. According to the study, EfficientNetB0 outperforms other pre-trained models, namely ResNet50V2 and Xception, which achieved an accuracy of 0.895 and f1 score of 0.8871.

Abstract

Late teens, namely in the age range 18 – 23 years, are the age range where teenagers tend to develop shopping habits, one of these shopping habits is compulsive buying (compulsive shopping). There are factors that influence the occurrence of compulsive buying in teenagers, one of which is self-control. This research was conducted to determine whether there is a relationship between self-control and compulsive buying in late adolescents who use food delivery services. The type of research carried out was quantitative research using a one-stage cluster sampling technique involving 147 late adolescents who live in West Denpasar sub-district. Data collection was carried out boldly using a questionnaire consisting of; The Self-Control Scale with a reliability coefficient of 0.896 and the Compulsive Buying Scale with a reliability coefficient of 0.35. Data analysis in this study used a simple linear regression test technique. The results of the simple regression test show a significance value of 0.000 (P<0.05). The results of these values ​​indicate that self-control has a significant influence on compulsive buying of 49.9% (R Square = 0.499; significance value 0.000 < 0.05). Thus, the higher the self-control they have, the lower the level of compulsive buying by young people who use food delivery services in West Denpasar.

Abstract

ABSTRACT Indonesia has a high potential for natural disasters due to its geological and geographical factors, such as tectonic activity at the convergence of three major world plates and the presence of many active volcanoes. The country’s high vulnerability to earthquakes also makes it prone to liquefaction and cyclic mobility, which can trigger ground settlement and structural damage. This research aims to expand understanding of liquefaction and cyclic mobility potential in South Tangerang and Wakatobi based on soil types and earthquake magnitudes. Two types of analysis were conducted. The cyclic stress method analysis compares cyclic resistance ratio (CRR) and cyclic stress ratio (CSR) using Idriss-Boulanger, Youd-Idriss, Seed et al., and Tokimatsu-Yoshimi methods. The Tsuchida (1970) method maps grain size distribution test data into curves with boundaries indicating susceptibility to liquefaction and cyclic mobility. Soil is considered to have potential for liquefaction and cyclic mobility if the majority of analysis methods confirm this potential. The results show that Wakatobi has a higher potential for liquefaction and cyclic mobility compared to South Tangerang, with susceptible soil layers reaching depths up to 24 meters. This is due to lower N-SPT values and shallow groundwater levels, increasing vulnerability during earthquakes.   ABSTRAK Indonesia merupakan negara dengan potensi bencana alam yang tinggi akibat faktor geologis dan geografis, seperti aktivitas tektonik di pertemuan tiga lempeng dunia serta keberadaan banyak gunung api aktif. Hal tersebut menyebabkan Indonesia berpotensi mengalami likuifaksi dan cyclic mobility yang dapat memicu penurunan tanah dan kerusakan struktur. Penelitian ini bertujuan untuk memperluas pemahaman tentang potensi likuifaksi dan cyclic mobility pada tanah di Tangerang Selatan dan Wakatobi berdasarkan jenis tanah dan skala kekuatan gempa. Penelitian menggunakan dua jenis analisis. Analisis cyclic stress method membandingkan nilai cyclic resistance ratio (CRR) dan cyclic stress ratio (CSR) menggunakan metode Idriss-Boulanger, Youd-Idriss, Seed et al., serta Tokimatsu-Yoshimi. Analisis menggunakan metode Tsuchida memetakan data uji distribusi ukuran butir tanah ke dalam bentuk kurva dengan batas-batas distribusi yang rentan mengalami likuifaksi dan cyclic mobility. Tanah dianggap berpotensi mengalami likuifaksi dan cyclic mobility apabila mayoritas dari metode analisis mengkonfirmasi potensi tersebut. Hasil analisis menunjukkan bahwa tanah di Wakatobi memiliki potensi likuifaksi dan cyclic mobility yang lebih besar dibandingkan Tangerang Selatan, dengan rentang lapisan tanah rentan hingga kedalaman 24 meter. Hal ini disebabkan oleh nilai N-SPT yang lebih kecil dan elevasi muka air tanah yang dangkal, sehingga lebih rentan mengalami likuifaksi dan cyclic mobility saat terjadi gempa bumi.

Abstract

This study analyzes factors influencing the job satisfaction of hotel employees in the tourism sector, focusing on innovation and employees’ active role in shaping their work environment. The study involves employees of 1- to 3-star hotels in Batam City, with 352 respondents selected through probability sampling. Data were collected through a 33-item Google Form questionnaire and analyzed using the PLS method with SmartPLS 4.0. The results show that job crafting and innovative work behavior do not directly affect job satisfaction but influence organizational support and employee engagement. Organizational support and employee engagement significantly affect job satisfaction and act as mediators in the relationship between job crafting and innovative work behavior with job satisfaction. Thus, employee job satisfaction cannot be built solely through job crafting or innovation but must be supported by organizational support and employee engagement. Keywords: Employee Engagement; Innovative Work Behavior; Job Crafting; Job Satisfaction; Organizational Support
