Abstract

Antrian dapat ditemui pada beberapa fasilitas pelayanan umum misalnya di Kantor Sistem Administrasi Manunggal Satu Atap (SAMSAT). Tujuan dari penelitian ini untuk mengetahui model sistem antrian yang saat ini diterapkan di Kantor SAMSAT Kota Tegal untuk mengetahui ukuran keefektifan proses pelayanan wajib pajak, dan memberikan sistem antrian yang optimal berdasarkan tingkat aspirasi. Dari hasil penelitian diperoleh bahwa pada SAMSAT Kota Tegal mengikuti model sistem antrian Single Channel Multiple Phase (antrian tandem atau seri). Rincian model antrian pada loket pendaftaran, pembayaran, dan penyerahan STNK adalah [G/G/1]:[GD/∞/∞]. Ini berarti sistem antrian mengikuti pola kedatangan yang berdistribusi General sedangkan waktu pelayanan berdistribusi General dengan jumlah pelayan meliputi 1 petugas di tiap loketnya. Hasil efektivitas dari sistem antrian di Loket SAMSAT Kota Tegal adalah hari Senin, 19 Maret 2018 dengan Lq = 5,0993, Ls = 5,7451, Wq = 12,6078, Ws = 14,2045, dan W = 35,42%. %. Pada hari Selasa, 20 Maret 2018 dengan Lq = 4,3054, Ls = 4,8791, Wq = 12,4754, Ws = 14,1375, dan W = 42,64%. Pada hari Rabu, 21 Maret 2018 dengan Lq = 4,1846, Ls = 4,7469, Wq = 12,4156, Ws = 14,0839, dan W = 43,77%. Pada hari Kamis, 22 Maret 2018 dengan Lq = 4,3002, Ls = 4,8947, Wq = 11,6106, Ws = 13,2158, dan W = 40,55%. Waktu menunggu yang diinginkan pengunjung dan pihak SAMSAT tidak lebih dari 20 menit dan waktu menganggur petugas yang diperbolehkan oleh SAMSAT Kota Tegal adalah 20% maka banyaknya petugas ideal pada tiap loketnya yaitu 1 orang petugas. Abstract Queues can be found in some public service facilities such as in SAMSAT Office (One Roof System).

This means the queuing system follows the General distributed arrival pattern while the General Distributed service time with the number of waiters includes 1 officer at each counter. The effectiveness of queuing system in SAMSAT of Tegal City is on Sunday, 19 March 2018 with Lq = 5,0993, Ls = 5,7451, Wq = 12,6078, Ws = 14,2045, dan W = 35,42%. On Tuesday, 20 March 2018 with Lq = 4,3054, Ls = 4,8791, Wq = 12,4754, Ws = 14,1375, dan W = 42,64%. On Wednesday, 21 March 2018 with Lq = 4,1846, Ls = 4,7469, Wq = 12,4156, Ws = 14,0839, dan W = 43,77%. And Thursday, 22 March 2018 with Lq = 4,3002, Ls = 4,8947, Wq = 11,6106, Ws = 13,2158, dan W = 40,55% Waiting time desired visitors and parties SAMSAT no more than 20 minutes and idle time officers allowed by SAMSAT of Tegal City is 20% then the number of ideal officers at each counter that is 1 officer.

Abstract

The Indonesia Stock Exchange categorizes companies into several business sectors. One of the sub sectors on the IDX is the cement sub sector. The author is interested in conducting research related to stock valuation in determining the intrinsic value of shares and measuring financial performance at PT Semen Indonesia (Persero) Tbk. (SMGR) and PT Indocement Tunggal Prakarsa Tbk. (INTP) as the leading in the cement industry in Indonesia and its relation to investment decision-making strategies. To reduce the risk in investing, investors must be able to analyze the company's financial statements, including its financial performance. The financial ratios used in this study are ROE (Return On Equity), EPS (Earning Per Share), DPS (Dividend Per Share), DPR (Dividend Payout Ratio), and PER (Price Earning Ratio). In addition, researchers also use SWOT analysis to find out the strategies that should be applied by the two companies. Based on the results of fundamental analysis and intrinsic value, it is concluded that in terms of financial ratios in the 2020-2022 period, INTP is slightly better than SMGR. However, based on intrinsic value at June 2023, SMGR is better than INTP because SMGR still tends to be undervalued when compared to INTP which tends to be highly overvalued.
