<p><span>Penilaian saham merupakan suatu hal penting yang perlu dilakukan bagi investor dalam melakukan kegiatan investasinya. Hal ini dilakukan dengan tujuan untuk meminimalisir risiko dan memaksimalkan keuntungan yang merupakan syarat dan karakteristik saham <em>hight risk</em> – <em>hight return</em>. Investor dapat melakukan penilaian saham secara fundamental yaitu dengan memperhatikan kondisi kinerja keuangan sebagai dasar untuk pengambilan keputusan. Penelitian ini dilakukan untuk mengetahui harga wajar suatu saham pada perusahaan subsektor perbankan pada periode 2021. Penilaian saham dilakukan berdasarkan dua pendekatan yaitu <em>Dividen Discount Model</em> dan <em>Price Earning Ratio</em>, dari 47 perusahaan subsekektor yang terdaftar sebanyak 12 perusahaan memenuhi kriteria dan dipilih sebagai sampel. Hasil penelitian menunjukkan bahwa dari 12 perusahaan terpilih, terdapat 10 perusahaan yang berada dalam kondisi undervalued dan 2 perusahaan yang berada dalam kondisi <em>overvalued</em>. Dalam kondis <em>undervalued</em> invetor dapat mengambil keputusan dengan membeli saham tersebut, sedangkan pada perusahaan yang berada pada <em>overvalued</em> invetor dapat menjual saham.</span></p><p><span><em>Stock valuation is an important thing that needs to be done for investors in carrying out their investment activities.</em><em> This is with the aim of minimizing risk and maximizing profits which are the terms and characteristics of hight risk – hight return. Investors can make stock valuation fundamentally by taking into account the condition of financial performance as a basis for decision making. This research was conducted to determine the fair price of shares in banking sub-sector companies in the 2021 period. Stock valuation was carried out based on two approaches, namely the dividend discounted model and the price earning ratio, of the 47 registered sub-sector companies, 12 companies met the criteria and were selected as samples. The results showed that of the 12 companies selected, there were 10 companies that were undervalued and 2 companies that were overvalued. In undervalued conditions, investors can make decisions by buying these shares, whereas in overvalued companies, investors can sell their shares.</em></span></p><p><span><br /></span></p>
Abstrak Proses produksi berarti menghasilkan suatu produk yang bernilai guna. Dalam suatu perusahaan pertambangan, produksi merupakan hal yang sangat penting, sehingga diperlukan perencanaan yang matang. Perusahaan menargetkan jumlah bahan galian yang akan diproduksi baik dalam jangka panjang, menengah maupun jangka pendek. Operasi produksi PT. Ifishdeco menggunakan bantuan alat gali muat excavator Komatsu PC 300 dimana terjadi penurunan produksi bijih nikel sebesar 19,94%. Target produksi sebesar 149.934 mt, namun capaian produksi hanya sebesar 116.603mt. Oleh karena itu, penelitian ini dilakukan untuk mengetahui faktor utama dan nilai probabilitas penyebab turunnya capaian produksi. Salah satu metode yang dapat digunakan untuk menganalisis faktor utama penyebab penurunan capaian produksi adalah menggunakan Fault Tree Analysis (FTA). Persamaan logika top down dari Fault Tree Analysis disubstitusi ke dalam aljabar Boolean hingga diperoleh minimal cut set. Minimal cut set merupakan persamaan akhir yang merincikan top down. Top event penurunan capai target produksi memiliki empat top down, yaitu faktor pengisian, kesiapan fisik alat, efektivitas kerja, dan waktu edar alat gali muat. Berdasarkan nilai probabilitas basic event tertinggi yang bernilai 1, maka faktor utama penyebab penurunan capaian produksi adalah dari faktor umur pakai alat tua, penjadwalan perawatan tidak teratur, kualitas alat buruk, dan proses selective mining. Abstract Analysis of Decrease in Nickel Ore Production Targets Using the Fault Tree Analysis Method in PT Ifishdeco, Southeast Sulawesi Province. Production process meant produce product with beneficial value. At the mining company, production was very important, so it needed to be well-planned. Company was making target amount of digging material to be produced in long term, middle term, and short term. Production operation at PT Ifishdeco utilized digger loader equipment namely excavator Komatsu PC 300. There was decreasing in nickel ore production of 19,94%. Production target was 149,934 mt, but the company was only able to meet 116,603 mt. Objective of this study was to know main factor and probability value which caused the low production performance. One of methods to be used to analyze the main factor was Fault Tree Analysis (FTA). Top down logical equations of Fault Tree Analysis was substituted into Boolean algebra to get minimal cut set. Minimal cut set was a formula of the top down and used to calculate probability. Top event of the decreasing of the production target had four top downs which were filling factor, mechanical availability, effectivity of use, and cycle time of digger loader. Based on the highest probability of basic event which value was equal to 1, the main factor caused the decreasing of productivity were lifetime of equipment, unscheduled of maintenance, low quality of equipment, and selective mining. Kata Kunci: Excavator, Work Effectivity, Boolean, Cut Set, Probability
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
