Inorganic Waste

Garbage is a classic problem causing environmental and ecosystem damage in every region, including in Bogor City. Plastic is one of the largest types of inorganic waste that causes ecosystem damage. In one day 1,7 tons of plastic waste are produced from a modern shopping center in Bogor. Several attempts were made to reduce the volume of inorganic waste. Since July 2018 the Regional Government of Bogor City has issued a regulation restricting the use of plastic bags in the modern market as an effort to reduce inorganic waste, especially plastic waste. Forecasting the volume of inorganic waste after the enactment of this regulation is needed as an evaluation step. The double exponential smoothing hole model is suitable for linear data trends. This is in accordance with the condition of inorganic waste volume data which tends to have a linear trend. Forecasting produces parameter parameter values α (level) 0,78 and γ (trend) 0,09 also MAPE 7,25%. The forecast results show that the volume of inorganic waste tends to increase in 2020. In order for this regulation to be optimal, it is necessary to consider applying these regulations not only in the modern market but also in the traditional market. In addition, it is also necessary to find an alternative to substitute for plastic so as not to switch to other inorganic types.

Double Exponential Smoothing

Aircraft has  became the best choice for long distance traveling because it has shortest travel time than any other transportations. Moreover, in recent years, aviation industries have competed for providing low cost flight so that it can also be enjoyed by middle class society. Thus escalate the popularity of aircraft as economical carrier. Knowing the volume of passengers in advance will help government and related institutions to effectively providing facilities. The volume of passengers can be predicted using classic model such as double exponential smoothing model which is simpler and has high accuracy. However, the randomness of Indonesian passenger volume data cause double exponential smoothing (DES) cannot follow both data pattern and data trend. Moreover, classic model often encounters overfitting where the prediction is bigger than the actual data. Therefore, we employed Grey Method applied on DES (GDES) to overcome this problem. GDES enabled the researcher to perform better data fitting because it would generate smoothing curve which showed clearer trend. As the result, although GDES fitting curve had higher error measurement (MSE) than DES, the forecasting result of GDES was more precise than DES. Keyword: Double Exponential Smoothing, Grey Method, Levenberg-Marquardt

The limited supply of Nalco raw materials from producers has become a problem for PT ABC, this has led to the control of raw material inventory at PT ABC not including good management, because in the management of raw materials the company still records inventory with manual systems and in ordering raw materials only based on estimates. From the results of the study, the forecasting method used is the Double Exponential Smoothing Holt's, Brown, and Holt Winters Additive Algorithm methods, from the three methods that are most suitable is the Double Exponential Smoothing Brown method with the smallest Mean Square Error of 256.2. Calculation of Sizing Lot by using Economic Order Quantity method, Least Unit Cost method, and Silver Meal method, of the three methods the most optimal is the Economic Order Quantity method because it has the lowest cost of Rp. 12,651,145. The calculation of Safety Stock gets 17 Pail results. and for Reorder Points for Nalco Water Treatment raw material, which is 29 Pail.

<p><em>PT. Charoen Pokhpand Medan merupakan perusahaan yang bergerak di bidang produksi dan penjualan produk pakan ternak. Namun ada beberapa kendala yang dihadapi oleh perusahaan yaitu sistem yang berjalan masih menggunakan microsoft excell dalam proses pencatatan dan pembuatan laporan produksi pakan ternak. Dan PT. Charoen Pokhpand Medan harus mendata satu persatu hasil produksi pakan ternak yang terjadi. Bagian produksi mengalami kendala dalam pembuatan laporan peramalan produksi pakan ternak dan untuk prediksi produksi pakan ternak pada periode berikutnya. Dan proses perhitungan peramalan produksi pakan ternak masih menggunakan perhitungan sederhana sehingga dalam penyampaian laporan produksi pakan ternak kepada pimpinan membutuhkan waktu yang lama tidak efektif dan efisien. Dalam proses perhitungan peramalan produksi pakan ternak sering terjadi kesalahan dan tidak sinkron dengan data penjualan sesungguhnya, dibutuhkan metode dalam perhitungan produksi pakan ternak ke periode berikutnya. Dengan menerapkan perbandingan metode triple exponential smoothing dan double exponential smoothing dapat membantu perusahaan dalam mengatasi masalah yang dihadapi oleh perusahaan. Karena triple exponential smoothing </em><em>digunakan ketika terdapat unsur trend dan perilaku musiman yang ditunjukkan pada data. Metode Exponential Smoothing yang dapat digunakan untuk hampir segala jenis data stasioner atau non –stasioner sepanjang data tersebut tidak mengandung faktor musiman.</em></p>
