Abstract

A process of buying and selling products, information and services that is carried out electronically by utilizing a computer network is often known as E-commerce and providing ease of payment, namely by using the ShopeePay and Shopee PayLater features. This study aims to find out which independent variables are variables that can influence purchasing decisions for Shopee users and find out which factors are more dominant in influencing purchasing decisions for Shopee users on the use of Shopeepay and Shopee PayLater features. Moreover, the trend of consumer behavior in the future also can be explored from the Zscore. The research method used is the method of Discriminant Analysis. The data collection technique was carried out by surveying 55 respondents through questionnaires. From the equation formed, consumers' tendency to buy or not to make purchases through Shopee E-Commerce is determined by the Customer Satisfaction variable in the transaction. Furthermore, from the Z value, the group that does not make purchases (0) has a Z value = 0.214, while the group that often makes purchases (1) has a Z = -0.207 value.

Abstract

Meningkatnya minat masyarakat dalam membuat Kartu Identitas Anak di Kabupaten Garut membuat volume pembuatan menjadi lebih banyak dan berdampak pada lambatnya proses pelayanannya. Hal ini terbukti dimana jumlah pengajuan rata-rata 70 orang per hari menjadi 150 per hari. Berdasarkan hal tersebut, tujuan dari penelitian adalah untuk mengidentifikasi dampak dari lambatnya pelayanan yang berakibat penumpukannya masyarakat di area pelayanan. Adapun metode yang digunakan adalah observasi, wawancara dan melakukan identifikasi pelayanan menggunakan SIPOC dengan cara berfikir  Lean dan siklus PDCA, kemudian dilakukan simulasi menggunakan Arena. Hasil dari penelitian menunjukan bahwa proses pengecekan data yang berulang, kartu tercetak lebih dari satu akibat penginputan data yang ganda atau gagal dalam pencetakan, menunggu verfikasi. Adapun proses pengiriman dokumen dari bagian administrasi ke area pengolahan data merupakan salah satu potensi terjadinya penumpukan dokumen karena lokasinya berbeda. Oleh karena itu, untuk meminimasi hal tersebut dilakukan usulan perbaikan  dan menghasilkan bahwa proses pelayanan KIA dapat dieliminasi dari 5 aktivitas menjadi  menjadi 4  serta petugas pelayanan dari 3 menjadi 2. Pemanfataan petugas menjadi efisien serta melakukan perbaikan layout untuk meminimasi pergerakan dengan memperhatikan proses bekerja dengan menggunakan 5S.

Abstract

Risk management is a management effort to control the company's risk operations by conducting risk analysis, risk evaluation and mitigation plan. Risk management efforts are feasible to be applied to the company's business activities including procurement activities. PT XYZ is one of the printing companies whose main demand is the printing of Elementary School Books. There is a decrease in demand that results in disruption to the company's cash flow so that a tight money policy is applied to every company's activity including procurement activities. This policy increases the risk that may occur, so risk management efforts are needed to minimize the impact that can occur. The House of Risk method is used to identify risk events and risk agents that cause them, and design mitigation measures to address those risk agents. The results showed that there were 10 risk events and 10 identified risk agents, with priority risk agents to be handled are A1 (volume and type of raw materials are incorrect) and A3 (communication interruption). There are 5 recommended mitigation measures.

Abstract

One of the risks in the workplace today is the risk of ergonomic hazards, apart from the risks of hazards that often occur such as risks of physical hazards and risks of hazards from the work environment. If the risk of physical hazards and the risk of environmental hazards already have many safety signs that are widely accepted, this is not the case with the risk of ergonomic hazards that do not yet have a validated and widely used safety sign. More fundamentally, awareness of the risks of ergonomic hazards is not fully understood by both workers and employer institutions. The method used in reviewing this paper is to enter the keywords safety sign, safety sign design, and ergonomic risk factors on google scholar and science direct.

Abstract

Green manufacturing mulai diimplementasikan secara luas pada industri manufaktur untuk mengurangi dampak negatif kegiatan industri pada lingkungan. Berbagai faktor, baik eksternal maupun internal, mempengaruhi implementasi green manufacturing. Hal ini menyebabkan implementasi green manufacturing tidak mudah untuk dilakukan. Penelitian ini membahas keterkaitan faktor internal perusahaan pada praktik green manufacturing, yaitu keterkaitan antara kapabilitas dinamis hijau perusahaan, kemampuan untuk menyerap pengetahuan (absorptive capacity) dan green manufacturing (dalam hal ini terdiri dari green design dan green process). Penelitian dilakukan pada 34 perusahaan manufaktur di Jawa Barat, Indonesia. Model penelitian terdiri dari empat konstruk dengan lima hipotesis keterkaitan antar konstruk. Hasil pengujian model menunjukkan bahwa green dynamic capability berpengaruh positif dan signifikan terhadap green process akan tetapi tidak berpengaruh pada green design. Absorptive capacity berpengaruh signifikan terhadap green dynamic capabilities dan berpengaruh secara tidak langsung terhadap green process. Hal ini menunjukkan bahwa kapabilitas dinamis berperan memediasi hubungan absorptive capacity dengan green process.

Abstract

Parkir dapat menimbulkan permasalah transportasi diperkotaan. Rendahnya okupansi ruang parkir sebuah fasilitas umum juga berdampak pada kemacetan lalu lintas di sekitarnya. Studi ini berfokus pada optimalisasi ruang parkir dengan mengukur tingkat okupansinya. Mikro simulasi diterapkan untuk mendapatkan gambaran okupansi secara spasial. Oleh karena itu, pendekatan agent based digunakan untuk dapat menangkap aspek mikro terutama perilaku pengemudi dalam mencari tempat parkir. Simulasi ini menggunakan tiga skenario dalam analisis okupansinya yaitu parkir yang terjadi pada hari kerja, hari akhir minggu, dan hari raya atau masa libur panjang. Hasilnya adalah okupansi tertinggi terjadi pada skenario hari raya khususnya pada area pintu masuk, railway, dan area mesin tiket. Sementara itu, area tunnel adalah area yang paling sedikit diminati oleh pengendara dan memiliki okupansi paling sedikit. Penambahan pintu masuk dan mesin tiket di dekat area tunnel dapat meningkatkan okupansi parkir yang berarti berpotensi dapat manambah okupansi kendarannya.

Abstract

This research investigated conditions of mental workload among workers in Indonesian small foodproducing business, and how work and workers characteristics might influence the workers’ mental workload. A corn chips business located in an industrial central of corn chips in Malang municipality, Indonesia was the research object, in which its seven workers were involved as participants. NASA-TLX measurement involving six mental workload subscales was deployed to observe the current state of workers mental workload, along with determination of mean WWL value as representation of mental workload level. Measured NASA-TLX subscales varied among tasks and subscales, with indications of exposures of mental workload to the workers. This was indicated by high ratings of Mental Demand, Temporal Demand, Effort, and Frustration subscales which reached 70, 80, 90, and 70, respectively. Mean WWL values were in the range of 46.00 to 70.67, with the highest value observed was on Task 2 with 70.67 and Task 5 has the lowest value of 46.00. It is suggested that tasks and workers characteristics could have different influence on the observed mental workload subscales ratings and WWL. This research provides base of understanding and findings on states of workers’ mental workload in Indonesian small food-producing business.
