Abstract

Group Technology System merupakan metode pengaturan fasilitas produksi (machine groups) yang dibutuhkan untuk memproses suatu part family tertentu ke dalam sel-sel manufaktur. Pengaturan tata letak di CV. Sonytex yang berdasarkan process layout mengakibatkan perusahaan menghadapi permasalahan berupa tingginya kebutuhan material handling. Salah satu kriteria kinerja dalam pembentukan sel manufaktur pada GTS adalah meminimasi total jarak material handling, sehingga dapat mengurangi biaya material handling dan meningkatkan produktivitas. Dalam penelitian ini digunakan tiga metode, yaitu Bond Energy Algorithm (BEA), Rank Order Clustering (ROC) dan Rank Order Clustering 2 (ROC2). Hasil dari penelitian ini adalah dengan menerapkan group technology systems diperoleh total pengurangan jarak material handling sebesar 70 m dan penghematan biaya material handling sebesar Rp 1.534.978,-. Berdasarkan model simulasi, relayout dengan metode BEA meningkatkan jumlah produksi sebesar 1 unit produk/hari dan penurunan waktu tunggu sebesar 0,575 menit.

Abstract

(The rise of e-commerce or online shops has made the number of shipping service companies increase. Delivery service companies need to analyze consumer preferences in selecting delivery services when shopping online so that they can continue to compete. This study aims to analyze the attributes or important factors that influence consumers and how much influence these factors have on consumer preferences. The AHP (Analytical Hierarchy Process) method is used to obtain the important factors and the discrete choice method with the multinomial logit model to analyze the influence of factors on consumer preferences. With the AHP method, three important attributes are obtained including cost with a value of 4.248, insurance with a value of 1.729, and delivery time with a value of 1.471. Judging from the influence on preferences, the cost factor and delivery time have a negative effect, which means that the lower the rate and the faster the time will increase customer satisfaction. While the insurance factor has a positive effect, which means that consumers prefer insurance. The most influential factor is cost with a parameter value of -1.97, then insurance with a parameter value of 1.66, and finally delivery time with a parameter value of -0.564. Based on gender, the results show that women's considerations of the cost attribute are higher than men's considerations. Meanwhile, based on allowance, the higher the allowance, the more important insurance and delivery time are considered.

Abstract

Persediaan dalam suatu unit usaha dapat dikategorikan sebagai modal kerja yang berbentuk barang. Keberadaannya di satu sisi dianggap sebagai pemborosan, tetapi di sisi lain juga dianggap sebagai asset yang sangat diperlukan untuk menjamin kelancaran pemenuhan permintaan. Persediaan yang terlalu banyak akan mengakibatkan biaya persediaan meningkat karena bahan yang rusak, terutama karena bahan telah melewati batas waktu kadaluwarsa. Untuk meminimalkan total biaya persediaaan, perusahaan dapat juga mengusahakan penurunan biaya pembelian yang bisa diperoleh dengan mempertimbangkan potongan harga pembelian dari pemasok bila memesan dalam jumlah yang besar. Dengan demikian perlu dicari persediaan yang memberikan biaya yang paling minimal dalam pengadaan persediaan. Penelitian ini dilakukan dengan tujuan untuk menghasilkan model perencanaan persediaan bahan baku dengan kendala keterbatasan waktu kadaluwarsa bahan dan terdapatnya faktor diskon, khususnya all unit discount quantity, yang diberlakukan oleh pemasok. Sedangkan model dasar yang digunakan yaitu model persediaan Economic Order Quantity (EOQ). Validasi model dilakukan dengan meniadakan unsur kadaluwarsa dan faktor unit diskon pada model. Validasi tersebut menyatakan bahwa model yang dikembangkan valid. Pada bagian akhir disajikan algoritma sederhana pencarian solusi model dan contoh numeriknya.

Abstract

Membuat produk dalam jumlah banyak menyebabkan pemborosan yang dapat mengurangi efisiensi produksi. Aktivitas yang paling banyak membuang waktu adalah aktivitas set-up mesin, untuk mengatasi masalah ini maka perlu diterapkan metode just-in-time dengan pembakuan kegiatan dan minimasi waktu set-up dengan mengambil kondisi real yang ada pada lantai produksi. Penelitian dilakukan di CV. Roda Jati, data yang digunakan adalah waktu penyelesaian komponen frame ujung produk GT 060 pada bagian permesinan dan waktu set-up mesin. Analisa meliputi : urutan kegiatan sekarang, usulan pembakuan kegiatan, perbaikan pembakuan kegiatan menggunakan minimasi waktu set-up, analisa menggunakan prinsip 5S. Hasil dari pengamatan didapatkan pembakuan kegiatan pada bagian permesinan dan mengurangi waktu set-up mesin. Waktu yang digunakan untuk memproduksi komponen tersebut sebelum dilakukan pembakuan kegiatan sebesar 4655,42 detik dan mengalami penurunan menjadi 4635,08 detik. Setelah dilakukan minimasi waktu set-up maka mengalami penurunan lagi mejadi sebesar 4296,31detik. Agar proses dapat selesai tepat waktu maka operator harus mentaati kegiatan yang telah dibakukan perusahaan dan dilakukan minimasi waktu set-up sebelum melakukan pekerjaan. Mempromosikan program 5S agar pekerja membiasakan diri untuk menjaga kerapian, kebersihan dan kedisplinan pada waktu berkerja.

Abstract

Research aims: As the dust of the COVID-19 pandemic settles, one apparent theme of the resulting economic crisis is uncertainties. The uncertainties especially hurt the MSMEs, which often possess limited organizational resources and capabilities. Referred to the ability to evolve as the environments do, resilience has been seen as a mantra for MSMEs’ survival and success. The purpose of the current study is twofold. Firstly, this study seeks to examine the effect of innovation, resource capability, and social capital on the resilience of MSMEs in Indonesia. Secondly, this study is aimed to examine the relationship between company performance and resilience.Design/Methodology/Approach: Employing a quantitative approach, hypothesis testing utilized Partial Least Square (PLS) data analysis techniques with the SmartPLS 3.0 program. The population in the current inquiry was MSMEs owned by families in Solo Raya, Indonesia. The number of MSMEs involved was 215 MSMEs owned by families.Research findings: Resource capability, innovation, and social capital were found to positively influence the performance of MSMEs, which in turn affected the resilience of MSMEs.Theoretical contribution/Originality: The research findings provide a business resilience construct in third-world, grassroots enterprises where social and cultural factors dominate.Practitioner/Policy implication: Governmental programs, such as exhibitions or workshops, aimed at strengthening MSMEs’ social capital and internal capabilities and cultivating innovation culture are encouraged to assist MSMEs’ survival during economic hardships.Research limitation/Implication: This study only focused on MSMEs in the Greater Solo Region of Central Java, Indonesia, during the COVID-19 pandemic. Further studies thus are encouraged to test the results in other economic and cultural settings.

Abstract

This paper aims to describe the development of a WebGIS application for the Muhammadiyah Regional Board of Central Java as a monitoring tool for the organization's Key Performance Indicator. The initial phase of the project involved conducting Focus Group Discussions (FGDs) to collect data regarding the organization's needs and requirements. Furthermore, the design process involved creating a comprehensive inventory of application functions and user interfaces. The use of WebGIS technology enables monitoring of key performance indicators (KPIs) and integration of spatial data. This enables more comprehensive visualization of performance data through interactive dashboards and spatial visualization. Further enhancements to the application were designed based on a thorough stakeholder review, taking into account comments obtained through the stakeholder review process. Once the application reached a satisfactory level of performance, it was formally introduced to stakeholders through a socialization process. The application was started and its security was verified using the reliable hypertext transfer protocol (HTTPS) via the URL https://kpi.pwmjateng.id. The implementation of the KPI monitoring tool based on WebGIS technology has yielded good results, and it is showing its success within the Muhammadiyah Regional Board of Central Java. Now, they can effectively monitor and track their indicators.
