Abstract

The hydrogen economy is a shift in the use of fossil energy to energy derived from hydrogen. Currently, Energy experts are trying to find fuel from new and renewable energy, especially in the transportation sector. This study seeks to determine the profile of energy consumption in the city of Semarang, especially in the transportation sector with simulation calculations in a certain year. By knowing the profile of energy consumption in the transportation sector in the city of Semarang, the output of this research is a planning study to build hydrogen economic infrastructure and make possible steps. At the end of this paper, it will be known how big the potential for hydrogen infrastructure development is so that later it can be a guide in determining the right policy in carrying out hydrogen infrastructure development in the city of Semarang. The design capacity of hydrogen production at PT. SAMATOR is 1000 m3/hour. Production breakdown per day : 550 m3/hour x 24hours = 13,200m3. If the production is maximized for 360 days per year, the total hydrogen production in Semarang is 4,752,000m3. In 2020, the demand for hydrogen in the city of Semarang = 1,955,780 m3. With this research data, it can be analyzed that hydrogen production in the city of Semarang can meet the needs of hydrogen for transportation in the city of Semarang.

Abstract

Pengelolaan kinerja forklift di Gudang Terminal Peti Kemas Semarang memiliki peran penting dalam keefektifan stripping barang impor Less Container Load (LCL). Tujuan penelitian (1) mengetahui hasil perhitungan nilai rata-rata availability ratio pada kinerja forklift dalam kegiatan stripping di Gudang Terminal Peti Kemas Semarang, (2) mengetahui hasil perhitungan nilai rata-rata performance ratio pada kinerja forklift dalam kegiatan stripping di Gudang Terminal Peti Kemas Semarang, (3) mengetahui hasil perhitungan nilai rata-rata quality ratio pada kinerja forklift dalam kegiatan stripping di Gudang Terminal Peti Kemas Semarang, (4) mengetahui hasil perhitungan nilai rata-rata Overall Equipment Effectiveness (OEE) di Gudang Terminal Peti Kemas Semarang. Metode penelitian yang digunakan adalah metode Overall Equipment Effectiveness (OEE) melalui tahapan-tahapan perhitungan (1) perhitungan data penurunan waktu forklift tahun 2023 (2) perhitungan nilai availability ratio (3) perhitungan nilai performance ratio, (4) perhitungan nilai quality ratio, (5) perhitungan nilai indeks Overall Equipment Effectiveness (OEE). Nilai rata-rata availability ratio adalah -0,1616666 %, dimana standar JIPM > 90 %, sehingga hasil menunjukkan ketersediaan forklift tahun 2023 rendah. Penyebabnya bulan Juni forklift mengalami kerusakan mpu board sehingga menjalani perbaikan selama 720 jam untuk waiting part modul fet fm dan board comp dan bulan Juli forklift mengalami kerusakan mesin forklift sehingga menjalani perbaikan selama 744 jam. Nilai rata-rata performance ratio adalah 106,7925 %, dimana standar JIPM > 95 %, sehingga hasil menunjukkan forklift memiliki kemampuan yang baik dalam pengangkutan produk. Nilai rata-rata quality ratio adalah 100 %, dimana standar JIPM > 99 %, menunjukkan kualitas pengangkutan barang baik. Nilai indeks Overall Equipment Effectiveness (OEE) adalah 9,99483 %, dimana standar JIPM > 85 %, menunjukkan produksi memiliki nilai yang rendah.
