Published: January 2024

This research constitutes a preliminary study aimed at determining the needs of teachers and students in the learning process, particularly in the context of physics subjects related to renewable energy. The chosen research method is a survey, conducted among 27 physics teachers and 59 high school students in MIPA field in Lampung Province using Google Forms. The collected data is then curated and analyzed to identify and address these educational needs. The results of the data analysis reveal a demand for learning programs that can enhance students' numeracy and literacy skills during the learning process. According to the survey, only 43% of teachers and 24% of high school students majoring in Mathematics and Natural Sciences are aware of the Sustainable Development Goals (SDGs). This aligns with the finding that only 40% of teachers have integrated PjBL-STEM into their learning programs. The worksheets lack activities that can stimulate students' numeracy and literacy skills, thereby impeding their active engagement in renewable energy learning. These findings are further corroborated by student questionnaires, which indicate that 55% of students feel they face limitations in understanding materials related to renewable energy. Additionally, 85% of physics teachers express concerns about students' difficulties in grasping the concept of renewable energy. Consequently, the development of an integrated renewable energy learning program incorporating PjBL-STEM becomes imperative.

Published: January 2024

International trade between Indonesia and China already has a cooperative relationship by following the ACFTA agreement or the ASEAN-China Free Trade Agreement. The implementation of the ACFTA should increase the value of exports, but in reality, commodities originating from China are easier to enter the domestic market. This has led to a decline in the condition of Indonesia's trade balance with China over the past 15 years. The purpose of this study is to determine the influence and magnitude of the influence of economic growth, inflation, and the exchange rate on the trade balance between Indonesia and China in the short and long term for the 2000-2021 period. The data used in this study is quantitative data obtained through secondary data in the form of a time series from 2000-2021. Data processing uses the Error Correction Model (ECM) with the Eviews 10 analysis tool. The results of the analysis show that the ECT is significantly negative and less than 1. This means that the model shows the level of short-term adjustment in correcting the long-term balance. According to estimates of economic growth and exchange rates in the short term have a negative effect on Indonesia's trade balance with China. Meanwhile, in the long run, the variable economic growth has a positive effect on the trade balance between Indonesia and China, while the exchange rate variable has no effect. The inflation variable has no effect either in the short term or the long term.

Abstrak. Indonesia sebagai negara agraris sektor pertanian memliki peran yang penting bagi perekonomian nasional. Sektor pertanian berperan penting sebagai sumber pendapatan, memenuhi kebutuhan pangan, dapat membuka lapangan pekerjaan, dan juga dapat berkontribusi terhadap pembangunan perekonomian di daerah seperti di provinsi Jawa Barat. Pada pelaksanaannya pada usaha sektor tani di temukan beberapa resiko salah satunya faktor iklim yang dapat menimbulkan kerugian. Curah hujan yang tinggi dapat membuat biji padi cepat membusuk dan mengakibatkan batang terlalu banyak menyerap air sehingga batang tidak mampu lagi menopang sehingga akan roboh. Berdasarkan hasil perhitungan yang telah dilakukan didapat bahwa curah hujan dapat mempengaruhi hasil panen dimana nilai curah hujan yang semakin tinggi menjadikan nilai trigger akan tinggi juga. Besarnya nilai trigger ini akan mempengaruhi besarnya nilai premi yang harus dibayarkan, besarnya nilai premi yang dihasilkan akan bertambah besar jika nilai trigger yang didapat juga semakin besar. Pada penelitian kali ini didapatkan lima pilihan nilai premi asuransi dengan nilai premi asuransi yang berada di antara persentil ke-5 sampai dengan ke-25.
Abstract. Indonesia as an agricultural country, the agricultural sector has an important role for the national economy. The agricultural sector plays an important role as a source of income, fulfills food needs, can create jobs, and can also contribute to economic development in regions such as West Java province. In its implementation in the farming sector, several risks were found, one of which was the climate factor which could cause losses. High rainfall can make rice seeds rot quickly and cause the stems to absorb too much water so that the stems are no longer able to support them so they will collapse. Based on the results of the calculations that have been done, it is found that rainfall can affect crop yields where the higher the rainfall value, the higher the trigger value will be. The magnitude of this trigger value will affect the amount of the premium value that must be paid, the amount of the resulting premium value will increase if the trigger value obtained is also greater. In this study, five choices of insurance premium values ​​were obtained with insurance premium values ​​that were between the 5th to 25th percentiles.

Abstrak. Prediksi harga saham digunakan oleh investor untuk memperkirakan pergerakan harga saham di masa depan, sehingga investor dapat membuat keputusan investasi yang lebih baik. Return saham adalah nilai yang menjadi acuan bagi investor dalam menentukan keuntungan. Fluktuasi harga saham menyebabkan ketidakpastian nilai return dan risiko saham yang diperoleh investor. Tujuan dari penelitian ini adalah membuat model harga saham menggunakan jump diffusion model untuk prediksi harga saham di masa depan. Pengukuran risiko dilakukan menggunakan analisis Value at Risk dengan simulasi Monte Carlo. Data yang digunakan dalam penelitian ini adalah harga penutupan (closing price) saham yang tergabung dalam IDX Quality 30, yang return sahamnya memiliki nilai kurtosis lebih besar dari 3 (leptokurtosis) sehingga data tersebut terindikasi adanya jump. Hasil yang diperoleh adalah model prediksi harga saham. Hasil prediksi harga saham IDX Quality 30 memiliki nilai MAPE kurang dari sama dengan 10%, menunjukkan tingkat akurasi yang tinggi. Analisis VaR dengan simulasi Monte Carlo pada tingkat kepercayaan 99%, 95%, dan 90% menunjukkan bahwa semakin tinggi tingkat kepercayaan yang digunakan, maka semakin besar pula tingkat risiko yang diperoleh investor. Berdasarkan saham yang memiliki nilai return yang tinggi atau risiko yang rendah, saham RMKE dan HMSP dipilih untuk investasi.
Abstract. Stock price predictions are used by investors to estimate future stock price movements, so that investors can make better investment decisions. Stock return is a value that becomes a reference for investors in determining profits. Stock price fluctuations cause uncertainty in the return value and stock risk obtained by investors. The purpose of this study is to model stock prices using a jump diffusion model for predicting future stock prices. Risk measurement is done using Value at Risk analysis with Monte Carlo simulation. The data used in this study is the closing price of stocks that are members of the IDX Quality 30, whose stock returns have a kurtosis value greater than 3 (leptokurtosis) so that the data indicates a jump. The result obtained is a stock price prediction model. The IDX Quality 30 stock price prediction results have a MAPE value of less than equal to 10%, indicating a high level of accuracy. VaR analysis with Monte Carlo simulation at 99%, 95%, and 90% confidence levels shows that the higher the confidence level used, the greater the level of risk obtained by investors. Based on stocks that have a high return value or low risk, RMKE and HMSP stocks are selected for investment.
