Abstract

PT. Indaco Warna Dunia is a decorative paint company in Indonesia that produces products under the brands Envi, Belazo, and Top Seal. Preliminary observations revealed that the forecasting method used by the company is ineffective and inaccurate. This inaccurate forecast result company’s problem in fulfilling the demand. This study aims to select the best forecasting method to improve forecast effectiveness and accuracy. The research was conducted at the Tarakan depot, and the products understudy were a fast-moving product category, specifically the Envi brand. Several forecasting methods such as Moving Average, Weighted Moving Average, Single Exponential Smoothing, Exponential Smoothing with Trend, and Holt's Double Exponential Smoothing. The accuracy of forecasting is the most important and it can be measured with MAPE (Mean Absolute Percentage Error). The results showed that Holt's Double Exponential Smoothing method is the best for three products, while the Exponential Smoothing with Trend method, and Single Exponential Smoothing method are the best for one of the products, respectively.

Abstract

Recently Indonesian textile and garment manufacturer has experienced a problem with shop floor production. The complexities in the manufacturing process led to many problems such as the inefficiency, and thus prevented the company from achieving its target. In fact, even though the company has established the efficiency target of 80%, the production floor cannot realize it. Thus, this research aims to increase the line efficiency to reach the company’s target. At the beginning of the analysis, the efficiency of assembly line was only 51,68%. Since, this value did not meet the company’s target and was not satisfying; the concept of ECRS was applied. The purpose of this research is to simplify the method to provide better effect and process flow. Before applying the method, the fishbone diagrams were used. The factors of man, method, machine and measurement were used to describe the root cause of the losses. Thus, after applying the concept of ECRS, the efficiency level increased to 81,54%, which had met the company’s target. The assembly line will run better and smoother with the smaller possibility of bottleneck if all of the workstations have a relatively balanced workload.

Abstract

The production methods at the Gum Rosin and Turpentine XYZ Factory involve several types of machinery and chemicals that might result in workplace accidents. Although the most recent Job Safety Analysis (JSA) was completed in 2018, various changes in work responsibilities have resulted in complaints from melting station workers in the case of eye irritation caused by turpentine vapor exposure and PGT waste workers as having the possibility of splashes from industrial waste. The purpose of this research is to assemble the most recent JSA document to eliminate potential dangers. This research was organized into four parts. The first stage involves conducting firsthand observations to describe the workers' responsibilities at each station. The second step includes interviewing the HSE staff and supervisors to determine the possible dangers of each operation. The third stage involves consulting with the HSE supervisor to decide on precautions to minimize possible dangers. The fourth stage consists of collecting JSA papers for each station. A total of 18 job descriptions with four categories of hazards were discovered based on the assembled JSA, including physical, chemical, mechanical, and ergonomic risks. Workplace safety recommendations here include the placement of safety signs, the installation of guardrails for waste tanks, and the application of personal protective equipment.

Abstract

Perusahaan XSMK merupakan salah satu perusahaan yang bergerak di bidang produksi furnitur. Departemen Marketing berperan penting dalam peningkatan penjualan produk pada perusahaan ini. Departemen Marketing pada saat PPKM diwajibkan untuk melakukan pekerjaan dari rumah kini diharuskan untuk kembali aktif bekerja di kantor ditambah dengan tuntutan harus memenuhi target penjualan di perusahaan, yaitu harus mendapatkan keuntungan lebih tinggi dari tahun sebelumnya. Oleh karena itu, peneliti melakukan penelitian dengan menggunakan metode NASA-TLX agar dapat melakukan pengukuran beban kerja mental pada karyawan bagian departemen marketing sehingga dapat diberikan rekomendasi yang berkaitan dengan beban kerja mental agar dapat meningkat efektivitas kerja karyawan. Hasil penelitian menunjukkan bahwa seluruh operator memiliki tingkat beban kerja mental dengan klasifikasi cukup tinggi hingga tinggi yang disebabkan oleh beragam factor antara lain Temporal Demand (TD) pada operator 1, Effort (EF) pada operator 2, dan Mental Demand (MD) untuk operator 3 dan 4. Rekomendasi perbaikan pekerjaan antara lain menyesuaikan beban kerja mental dengan kapasitas kerja dan kemampuan operator yang bersangkutan, menyesuaikan jam kerja terhadap tuntuan target harian karena menimbang banyak juga tuntutan di luar pekerjaan, memberikan kesempatan pada operator untuk mengembangkan kemampuannya.

Abstract

Instalasi Farmasi Rumah Sakit memiliki persediaan obat – obatan dengan berbagai jenis dan fungsinya. Mengingat banyaknya macam obat pada instalasi farmasi, maka perlu ditentukan prioritas obat yang akan dioptimalkan, salah satunya menggunakan metode ABC Indeks Kritis. Berkaitan dengan ketidakpastian pemakaian, perlu dilakukan pengendalian persediaan yang ditujukan untuk menjamin terpenuhinya kebutuhan obat untuk pasien dengan biaya persediaan yang minimal. Metode yang dapat digunakan pada kondisi ketidakpastian adalah metode Periodic Review System. Berdasarkan analisis ABC Indeks Kritis, dari 2039 jenis obat 76 jenis diantaranya termasuk kategori A atau Vital, dengan indeks kritis tertinggi adalah ATS 1500 Injeksi dan Fentanyl 0,05 Mg/Ml 2 Ml Injeksi. Kondisi optimal ATS 1500 Injeksi tercapai jika dilakukan pemesanan setiap 8 hari, dengan persediaan maksimum yang diharapkan = 12,69 ≈ 13 ampul, kebijakan ini akan menghasilkan servise level (η) =96,76%, sedangkan kondisi optimal Fentanyl 0,05 Mg/Ml 2 Ml Injeksi tercapai jika dilakukan pemesanan setiap 10 hari, dengan persediaan maksimum yang diharapkan = 24,37 ≈ 25 ampul, kebijakan ini akan menghasilkan servise level (η) = 89,96%
