Abstract

Entering the era of globalization, economic shifts and market trends are increasingly fast and difficult to predict, so the role of information as the main ingredient of decision making in companies becomes important. This study aims to determine the effect of information sharing (IS) on supply chain performance (SCP) which is mediated by the company relationship (CR). The survey was conducted through distributing questionnaires to 48 samples of batik SMEs in Yogyakarta city selected by simple random sampling method then the data was analyzed using path analysis with SPSS 15. The results of the study found a significant positive effect of IS on SCP indicated by the correlation coefficient (R) of 0.374 and t count> t table at a significance level of 5% (4,976> 2,014). Then the significant positive effect of IS on CR is shown by the value of the correlation coefficient (R) of 0.453 and the value of t count> t table at the significance level of 5% (4.540> 2.014). Then the significant positive effect of CR on SCP is shown by the value of the correlation coefficient (R) of 0.360 and the value of t count> t table at the significance level of 5% (3.896> 2.014). Finally, the significant positive effect of IS on the SCP that is mediated by CR is shown by the sum of the coefficients of 0.537 then tested using the sobel test and produces z count> t table at a significance level of 5% (3.078> 2.014). This research contributes to the development and theoretical application, especially in the field of operational management.

Abstract

Limestone is a rock belonging to the type of sedimentary rock, formed as a result of a natural sedimentation process. Limestone is a type of non-metallic mineral that is used in various sectors, such as in the paint industry, glass industry, plastics, paper industry, liming on agricultural land and is also used in the metal smelting industry. Limestone products produced by PT. Sugih Alamanugroho is in the form of calcium carbonate flour (powder) with sizes of 800 and 1,200 mesh. Before being marketed, calcium flour will go through a series of quality analysis processes to determine moisture content, degree of whiteness and residual weight (+800 mesh). The water content test was analyzed using an infrared moisture determination balance tool, aiming to find out what percentage of the water content contained in limestone and calcium carbonate flour. The degree of whiteness was analyzed using a reflectometer. Residual testing was carried out by weight pf the residue after the drying process was carried out in the oven. Based on the data, the calcium carbonate flour produced has passed the quality test, with a moisture content <0.03%, a whiteness degree >89.6% and a residual weight (+800 mesh) <0.05% in accordance with the quality standards of limestone and calcium flour. carbonates that have been determined by the company. So that the packaging and marketing process can then be carried out.Keywords: Limestone, Calcium Carbonate Flour, Moisture, Whiteness, Residue Weight

Abstract

PT Harmak Indonesia adalah perusahaan yang bergerak di bidang penambangan dan peremukan andesit. Pabrik peremukan andesit ini terletak di Desa Hargowilis, Kecamatan Kokap Kabupaten Kulon Progo Daerah Istimewa Yogyakarta. Penelitian ini dilakukan untuk mengkaji secara teknis penyebab unit peremuk belum mencapai target produksi yang ditetapkan yaitu sebesar 850ton/hari. Produksi yang dihasilkan saat ini sebesar 620,3ton/hari dengan material yang dihasilkan yaitu produk ukuran - 20+10mm sebesar 47,18% atau 50,28ton/jam, -10+5mm sebesar 26,84% atau 28,61ton/jam dan -5mm sebesar 25,98% atau 27,69ton/jam. Target produksi yang diharapkan sebesar 850ton/hari dengan rincian produk ukuran - 20+10mm sebesar ≥46% atau ≥ 382,5ton/hari, -10+5mm ≥27% atau ≥ 212,5ton/hari dan -5mm sebesar ≤27% atau ≤ 229,5ton/hari. Berdasarkan rincian data tersebut dapa diketahui bahwa target produksi harian belum tecapai. Perbaikan yang dilakukan yaitu memaksimalkan jumlah umpan yang di produksi oleh pabrik peremuk sehingga efektivitas alat menjadi maksimal. Selain itu, untuk meningkatkan produk harian perlu dilakukan perbaikan pada waktu hambatan kerja yang masih terlalu banyak sehingga dapat meningkatkan waktu kerja efektif. Setelah dilakukan perbaikan dengan menambah umpan, direncanakan target produksi harian dapat tercapai dengan jumlah 128,42ton/jam atau 875,82ton/hari dengan rincian produk -20+10mm sebesar 60,14ton/jam atau 46,83%, -10+5mm sebesar 34,92ton/jam atau 27,19%, dan -5mm sebesar 33,36ton/jam atau 25,98%. Adapun untuk waktu kerja efektif dapat ditingkatkan secara bertahap dengan mengurangi waktu hambatan yang dapat dihindari dengan berpatokan pada waktu hambatan terkecil pada bulan sebelumnya yaitu sebesar 145menit/hari dimana terjadi pengurangan sebesar 16menit/hari. Sehingga waktu kerja efektif meningkat menjadi 480,82menit/hari atau 7,1jam/hari. Dengan demikian produksi perhari menjadi 911,78ton/hari.

Abstract

PT. Nusajaya Persadatama Mandiri yang merupakan owner dari PT. Ghetsemani Indah, WAS, dan BSA adalah perusahaan yang bergerak di bidang pertambangan bijih Nikel. PT. Nusajaya Persadatama Mandiri menggunakan sistem penambangan tambang terbuka dengan metode Open Pit Selective Mining. Kegiatan utama pada penambangan tersebut terdiri dari pengupasan lapisan tanah penutup, pembongkaran, pemuatan dan pengangkutan bijih Nikel dari lokasi penambangan Pit A dan Pit B menuju Stockpile yang berada di luar pit penambangan dilanjutkan pemuatan dan pengangkutan menuju kapal tongkang/Jetty. Pengangkutan Bijih Nikel menuju Stockpile dilakukan untuk pemisahan bijih nekel sesuai kadar Ni hasil dari pemisahan kadar Ni di stockpile tersebut akan diangkut dan muat di kapal tongkang. Alat mekanis yang dibutuhkan dalam kegiatan pengangkutan bijih Nikel dari stockpile menuju kapal tongkang adalah alat gali muat dan alat angkut. Kombinasi alat mekanis yang digunakan adalah 1 alat gali muat excavator Caterpillar dan 8 alat angkut Dump Truck Quester CWE 370. Permasalahan yang terjadi adalah belum tercapainya target produksi pada alat angkut sebesar 100.000 ton/bulan. Berdasarkan hasil penelitian, kemampuan produksi alat muat saat ini adalah 171.154 ton/bulan tercapai sebesar 171% dari target produksi dan kemampuan produksi alat angkut saat ini adalah 91.834 ton/bulan tidak tercapai sebesar 91,8% dari target produksi. Maka dari itu, perlu dilakukan optimalisasi kerja alat muat dan alat angkut sehingga dapat mencapai target produksi yang diinginkan.

Abstract

Perkembangan ekonomi di Indonesia menyebabkan persaingan bisnis yang sangat ketat. UMKM (Usaha Mikro, Kecil, dan, Menengah) menjadi bagian yang sangat penting bagi perekonomian di Indonesia. UMKM menjadi kontributor terbesar terhadap PDB nasional Indonesia. Salah satu sektor yang berkontribusi bagi perkembangan ekonomi adalah sektor konveksi. UMKM konveksi memiliki potensi yang sangat besar dikarenakan perkembangan model yang berubah dari waktu ke waktu. Akan tetapi, UMKM konveksi tak lepas dari berbagai tantangan dalam hal rantai pasok. Ketidakstabilan harga bahan baku, keterbatasan stok, dan lamanya waktu tunggu menjadi masalah yang harus dihadapi oleh UMKM konveksi. Penelitian ini bertujuan untuk menguji dan melihat pengaruh long-term relationships, information sharing, agile, dan supply chain collaboration terhadap supply chain performance pada UMKM konveksi di Kabupaten Sleman. Supply chain collaboration dalam penelitian ini terdiri atas supply chain application dan supply chain capability. Pengambilan sampel dalam penelitian ini menggunakan teknik purposive sampling. Penelitian ini menggunakaan metode analisis partial least square (PLS) melalui software SmartPLS 3.0 untuk menganalisis hipotesis. Hasil penelitian ini menunjukkan bahwa long-relationships dan supply chain application berpengaruh positif dan signifikan terhadap supply chain performance, serta supply chain application berpengaruh positif dan signifikan terhadap supply chain capability.
