Synthesis of Heterogeneous Catalysts NaOH/CaO/C From Eggshells for Biodiesel Production Using Off-Grade Palm Oil

A heterogeneous catalyst, such as Calcium Oxide (CaO), is widely used in biodiesel production due to its various advantages over homogeneous ones. The optimum condition for synthesizing this catalyst is determined by calcination temperature and mass ratio. As a result, a modification is required to increase its performance in improving the biodiesel yield. In this study, eggshell waste was modified by calcination, hydration, and dehydration methods integrated with activated carbon and NaOH. It is used as a heterogeneous base catalyst for off-grade palm oil transesterification reactions. The results shows the catalyst with the highest activity is obtained at calcination temperature of 800°c and mass ratio of 7 to 3. This is achieved with transesterification reaction conditions, which include a mole ratio of methanol/oil 6 to 1, catalyst concentration of 6%-b oil, and temperature 70°c for 3 hours, yielding 79.08% of the biodiesel. Additionally, CaO, Na2CO3, and Ca (OH) 2 materials were found in the catalyst with a catalyst alkalinity value of H greater than 9.3 through X-ray diffraction (XRD) analysis. Several methyl esters, such as palmitate and oleate were also found in biodiesel through Gas Chromatography-Mass Spectrometry (GC-MS) analysis

Meningkatkan Keterampilan Menulis Puisi Menggunakan Media Visual Gambar Siswa Kelas IV SDIT Hidayatul Jannah

This study aims to improve the ability to write poetry in grade 4 students at SDIT Hidayatul Jannah and to find out students' difficulties in carrying out poetry writing activities. This type of research used a qualitative descriptive research method. Qualitative research method is a method used to examine the condition of natural objects where the researcher is the key instrument. The research subjects were fourth grade students at SDIT Hidayatul Jannah. Data collection techniques used are observation, interviews and literature/documentation studies. The results showed that the ability to write poetry for fourth grade students at SDIT Hidayatul Jannah was still relatively low, because the language used in writing poetry still used everyday language
