Abstract

Rain is a source of water where water is an important element in life, one of which is in the agricultural sector. High rainfall can cause floods which cause damage to agricultural crops so that farmers will experience crop failure. In 2021, 2,591 hectares of rice fields in Muaro Jambi Regency experienced crop failure due to flooding caused by high rainfall. This is an important reason to predict the amount of rainfall in Muaro Jambi Regency so that it can help in making decisions to anticipate crop failure. Rainfall is often difficult to predict, so it is necessary to identify data patterns to determine the appropriate method and determine the best model that can be used to predict the amount of rainfall in Muaro Jambi Regency. The results of identifying rainfall data patterns in Muaro Jambi Regency show that the rainfall data in Muaro Jambi Regency contains seasonal patterns. SARIMA is a forecasting method that is suitable for application to data that contains seasonal patterns. The best model that can be used to predict the amount of rainfall in Muaro Jambi Regency is the SARIMA(1,0,0)(1,0,0)12 model with forecasting accuracy classified as very good with a MAPE value of 0.05041% and an MSE of 8959 .8 which is obtained from calculating the error value between the actual data and the forecast results on outsample data.

Abstract

Penelitian ini dilatarbelakangi oleh proses pembelajaran saat ini di masa pandemic covid 19 yang mengakibatkan pembelajaran dilakukan secara daring sehingga dituntut untuk menggunakan teknologi dan untuk meningkatkan kemampuan berpikir tingkat tinggi. Penelitian ini bertujuan untuk mendeskripsikan hasil desain dan kualitas ELMOLUS berbasis android berbantuan sigil menggunakan concept rich instruction dengan pengaplikasian live worksheet. Penelitian ini mendesain dan mengembangkan dengan menggunakan model pengembangan ADDIE yang diawali tahap analisis, desain, pengembangan, implementasi dan dilakukan evaluasi setiap fase. Pada penelitian ini menghasilkan produk berupa e-modul untuk mahasiswa pada materi kalkulus. ELMOLUS ini didesain menggunakan pendekatan concept rich instruction dengan lima karakteristik yaitu practice, decontextualization, encapsulating a generalization in words, recontextualization dan realization. Berdasarkan uji validasi dan uji praktikalitas, diperoleh hasil dari validasi oleh ahli materi dan ahli desain dengan persentase berturut-turut 88% dan 89,4% dengan kriteria “sangat valid”. Dan untuk hasil uji kepraktisan dari uji coba perorangan diperoleh dengan persentase 88,8% dan uji coba kelompok kecil diperoleh dengan persentase 85%, sehingga pada kriteria persentase kepraktisan didapatkan kriteria “sangat praktis” dengan revisi kecil.

Abstract

A capital market is a market in which long-term trading of financial assets takes place, or a market in which various financial instruments are traded. The development of capital markets promotes the economic development of the country. The form of investment in the capital market is in the form of shares. Because stock prices are constantly fluctuating, capital market participants need analysis to help predict future stock prices. PT Aneka Tambang TBK or ANTM for short is one of the stocks traded in Indonesia's capital market. This study applied the Box-Jenkins ARIMA method for the period from July 2021 to November 2021 to determine the optimal forecast model for stock price fluctuations of ANTM, and obtained forecast results in December 2021. It is intended to The best preserved model is his ARIMA model (3,2,0) and ANTM's December 2021 stock price forecast results are down.
