Abstract

Pengukuran tingkat produktivitas organisasi atau perusahaan penting dilakukan untuk mengevaluasi pencapaian dan melakukan perbaikan pada indikator produktivitas yang kurang baik. Tujuan penelitian ini adalah mengetahui tingkat produktivitas dari sebuah perusahaan dan mengevaluasi indikator yang kinerjanya paling buruk. Studi kasus dilakukan pada perusahaan dompet kulit yang sedang mengalami penurunan produktifitas selama periode tahun 2018, dimana jumlah produksi tidak mencapai target yang diharapkan sehingga harus menambah jam kerja/lembur untuk mencapai target. Dengan penambahan jam kerja, perusahaan mengeluarkan biaya lembur karyawan. Metode untuk mengukur tingkat produktifitas perusahaan adalah metode objective matriks atau OMAX dan penelitian ini mengacu pada langkah-langkah OMAX, yaitu menentukan kriteria produktivitas pada lini produksi, penentuan bobot, penentuan level-level pada objective matrix, perhitungan index produktivitas, dan analisa produktifitas dengan traffic light system.  Pembobotan untuk menentukan bobot setiap indikator produktifitas dengan sistim linkert.  Selanjutnya digunakan Traffic Light System (TLS) untuk pengelompokan level pencapaian indikator dan melakukan perbaikan untuk level indikator yang buruk. Hasil penelitian menunjukkan nilai rata-rata produktifitas keseluruhan pada tahun 2018 adalah 5,410. Indeks produktifitas tertinggi dicapai pada bulan Agustus sebesar 62,59%. Dari traffic light sytem, diketahui bahwa indikator produktifitas yang paling buruk adalah pada faktor defect/cacat. Indikator produk cacat perlu perhatian khusus dalam rangka perbaikan untuk meningkatkan tingkat produktifitas perusahaan.

Abstract

The energy demand of the world is foreseen to be increased due to improvements on the living standard of developing countries and the development of global economy. The increase in sustainability of energy supply must be considered as a must to avoid spoiling natural resources for the next human generations and more dramatic effects such as global atmospheric warming. The utilization of CO2-free energy sources, as renewable energy, is one of the most promising way. Nevertheless, massive energy production with such energy sources are far from being practically feasible in short-medium term and an innovative solution should be put implemented CO2. This general assumption is also applicable to any energy carrier such as hydrogen or electricity. In this paper, analysis of the hydrogen production processes conducted and the discussion of the need to develop a CO2- free production scheme like methane cracking is shown

Abstract

Competitive advantage is the keyword for Small Medium Enterprise (SME) to survive. One of the effort that could be conducted by the SMEs is doing temporary cooperation. The SMEs would arrange work contract hence all of the SMEs could work in same corridor. Development of Information Technology (IT) will support such cooperation and the SMEs would form a Virtual Organisation (VO). In VO, the management is called as meta-management, that contained several actions to coordinate all of the SMEs in the VO. Technically, the meta-management contained basic activities including analysing and tracing prerequisites, allocating requirements fulfilment and adjusting optimum criteria for every UKM. In term of management control, it requires a tool to measure success of the meta-management so that strategic actions could be arranged for future improvement. This paper presents the use of Fuzzy Logic (FL) to measure success of a meta- management. The success itself is measured based on the three aspects explained above, and the proposed FL is used to model uncertainties in every aspect. A numerical example from previous research is taken to show how the proposed method works.
