Abstract

Persaingan industri manufaktur di Indonesia semakin ketat, sehingga mendorong industri untuk berlomba-lomba meningkatkan kualitas produknya. PT. Jawa Metalindo Prima  adalah salah satu industri manufaktur yang memproduksi stud bolt, dimana masih sering ditemukan kecacatan dalam proses produksinya. Penelitian ini bertujuan untuk mengimplementasikan metode Six Sigma pada produksi stud bolt guna meminimalisir kecacatan produk dan meningkatkan kepuasan pelanggan. Metodologi ini didasarkan pada pendekatan Define, Measure, Analyze, Improve, and Control (DMAIC). Rata-rata hasil perhitungan nilai DPMO dan Sigma Level adalah 8696,02 dan 3,88, dimana masih belum dapat diterima karena masih jauh dari 6 sigma. Penyebab cacat tertinggi adalah ketidaksesuaian persentase perpanjangan dalam 4D yaitu sebesar 48%. Setelah dilakukan analisa, akar penyebab masalah produk cacat adalah operator yang kurang memiliki pengetahuan. Berdasarkan analisis 5W + 1H kebijakan yang harus diambil untuk meningkatkan kualitas stud bolt adalah selalu memperbarui work instruction dan melakukan pengawasan yang ketat pada setiap critical to quality.

Abstract

There are main activities of the worker in UD Askan such as splitting the fish, carrying, and lifting the tubs. Work activities are done manually and the production process continually undergoes. The frequency of activity (15 cycles) in a day causes the risk of fatigue, injury, and Musculoskeletal Disorders (MSDs). Evaluation of the work posture of four workers by Ovako Working Posture Analysis System (OWAS) and Job Strain Index (JSI) methods showed high risk in the process of lifting and carrying a tank. The previous posture caused the worker to bend forward, both legs standing or squatting with both knees, and walk by carrying a tub. The results recommend solving soonest due to the danger to the musculoskeletal. The recommendation shows that lifting methods are required and the design of lifting and transporting equipment is needed. The evaluation posture by OWAS show that the process of carrying a tank is 3 level (immediate repair because it is harmful to the musculoskeletal), and after improvement, it is 1 level (not harmful to the musculoskeletal). Then, JSI indicates any improvement from the 3 levels (posing a hazard) to level 1 (safe work).

Abstract

The COVID-19 pandemic impacted several small and medium-sized enter­prises (SMEs) in Indonesia. The viability of some SMEs' business opera­tions was disturbed, especially those who create non-essential goods like carving. The sales have decreased by up to sixty per cent, causing reduced levels of income and the termination of numerous workers. SMEs in Indonesia are highly considered because businesses are one of the country's most significant economic contributors. This research proposes a strategy for SMEs to improve the resilience of business operations of the SMEs. The K-means method was used to investigate three groups of SMEs: micro, small, and medium. Changes in the SME class before and after the pandemic are investigated through changes in the values of the variables in the SME profile. Then the SWOT method is used to identify internal and external factors with the highest weight, which can be used as a basis for developing strategies to increase the resilience of SMEs. Furthermore, the TOPSIS method determines the best plan for dealing with the new digital era. The result shows that the W-T strategy to utilize social media can be prioritized based on the criteria that significantly impact SMEs' product sales and business resilience.

Abstract

Krisis suatu komoditas merupakan kondisi yang diakibatkan oleh kelangkaan keberadaan komoditas tersebut. Kelangkaan komoditas umumnya ditandai dengan peningkatan harga komoditas. Salah satu komoditas yang rawan mengalami krisis yaitu komoditas CPO (Crude Palm Oil). CPO merupakan bahan baku utama pembuatan biodiesel dan minyak goreng. Antisipasi terhadap krisis komoditas perlu dilakukan terutama oleh pihak-pihak yang berkepentingan seperti pemerintah, industri, dan investor. Oleh karena itu, diperlukan suatu sistem peringatan dini yang dapat memberikan peringatan awal akan terjadinya suatu krisis. Pengembangan sistem peringatan dini untuk krisis komoditas CPO di Indonesia dilakukan dengan metode analogi dengan sistem peringatan dini untuk krisis mata uang. Pendekatan yang dikembangkan adalah non parametrik. Tahap penting yang dilakukan adalah menentukan variabel krisis dan indikator-indikator terjadinya krisis komoditas tersebut. Sebagai variabel krisis digunakan CMPI (Commodity Market Pressure Index). Indikator krisis yang digunakan adalah harga CPO luar negeri, harga minyak mentah dunia, tingkat inflasi, nilai tukar rupiah terhadap $US dolar, PDB, produksi CPO dan ekspor CPO. Penelitian ini menggunakan data bulanan dari Januari 2000 hingga Juni 2007. Dengan menggunakan ukuran performansi POPCC (percent of observation periods correctly called), dilakukan perbandingan model nonparametric. Hasil analisis tersebut menunjukkan bahwa indikator yang berkorelasi kuat terhadap krisis komoditas CPO adalah harga CPO luar negeri, harga minyak mentah, nilai tukar rupiah, PDB dan produksi CPO. Kata kunci: sistem peringatan dini, krisis komoditas, pendekatan sinyal, nonparametrik
