Fly ash can be used and utilized as an adsorbent because it is cheap and effective to adsorb waste in the aquatic environment. Hg also known as Mercury is a carciogenic heavy metal and potentially threatens human health at very low concentrations. In this study, fly ash was applied as the adsorbent for Hg2+ in the form of chitosan-fly ash composite pellet and was cross-linked with glutaraldehyde in order to know how much the mass of pellets that can be used to lower the concentration of Hg2+ in solution. The results showed that the fly ash can be compositated with chitosan gel after going through the process of physical-chemical activation so that it can be formed into adsorbent pellets/granules. The optimum condition was obtained from adsorbent pellets of fly ash-chitosan composite crosslinked with glutaraldehyde after contacted with a solution containing Hg2+ with the pellet mass of 3 g.Keywords: composite, fly ash, glutaraldehyde, pellets

Penelitian ini bertujuan untuk mengetahui perbedaan antara harga yang disarankan oleh indikator MACD dan indikator RSI dengan close price terdekat saham. Penelitian ini juga bertujuan untuk mengetahui perbedaan antara indikator MACD dengan indikator RSI pada saham JII tahun 2016 s.d. 2018. Jenis penelitian ini adalah deskriptif kuantitatif dan komparatif. Teknik purposive sampling menghasilkan 6 saham sebagai sampel penelitian dengan kode: ADRO, BSDE, KLBF, PTPP, SMRA, dan WIKA. Teknik analisis data pada penelitian ini menggunakan aplikasi ChartNexus Versi 5 untuk menganalisis harga saham harian dengan indikator MACD dan RSI. Sinyal harga dari indikator kemudian dipasangkan dengan close price terdekat saham. Hipotesis penelitian diuji menggunakan uji beda Mann Whitney yang diolah dengan program SPSS 23. Hasil penelitian menunjukkan bahwa tidak terdapat perbedaan antara harga dari sinyal indikator MACD dan RSI dengan close price terdekat saham, sehingga sinyal beli dan sinyal jual yang dihasilkan akurat dan dapat digunakan dalam perdagangan saham. Hasil penelitian juga menunjukkan bahwa tidak terdapat perbedaan antara 2 indikator analisis teknikal, sehingga dapat dinyatakan bahwa pada obyek dan periode yang sama, indikator MACD dan RSI menghasilkan keputusan investasi (sinyal beli dan sinyal jual) yang sama secara statistik.

Karakterisasi pori dari pellet komposit abu layang dan kitosan sebagai adsorben telah dilakukan. Komposit adsorben dibuat dengan campuran abu layang dan kitosan yang diikat silang menggunakan glutaraldehyd dengan perbandingan setiap 2 g, 3 g dan 4 g abu layang dalam 20 mL larutan kitosan yang sudah dilarutkan dalam larutan 5% asam oksalat. Karakterisasi adsorben dilakukan menggunakan Gas Sorption Analyzer untuk mengetahui karakter pori dari abu layang, kitosan dan adsorben komposit. Dari hasil penelitian diperoleh bahwa adsorben dengan abu layang sebanyak 3 g dalam 20 mL larutan kitosan memiliki luas permukaan dan volume total pori terbesar yaitu 31,00 m2/g dan 4,54 (e-02 cc/g) dan rerata jari pori terkecil yaitu 29,30 Å. Serta identifikasi gugus fungsi komposit abu layang-kitosan dari spektrofotometer inframerah menunjukkan adanya gugus fungsional untuk menyerap logam berat yang terlihat pada bilangan gelombang 3433 dan 2932 cm-1.
