“…Peta karakteristika pantai tersebut menunjukan bahwa daerah tapak pelabuhan menempati pantai dataran rendah dengan kemiringan paras pantai kurang dari 10° tersusun oleh pasir lepas dengan panjang mencapai beberapa kilometer dan lebar sekitar puluhan sampai ratusan meter (Setiady dan Sarmili, 2015). Pesisir Palabuhanratu berhadapan langsung dengan Samudera Indonesia di sebelah selatanbaratdaya dimana terjadi proses kesetimbangan dinamis antara suplai sedimen dari daratan dan aktivitas hidro-oseanografi membentuk pantai pasir selama ini dan berjalan secara evolutif tanpa turut campur tangan manusia (Gambar 6a).…”

Di Palabuhanratu - Kabupaten Sukabumi, sedang dibangun pelabuhan baru untuk mempermudah konektivitas antar wilayah di Jawa Barat selatan dan diharapkan dapat menjadi pelabuhan lintas provinsi yang mampu mengangkat pertumbuhan ekonomi khususnya di bidang wisata bahari. Namun demikian, saat ini perkembangan pembangunan pelabuhan tersebut nampaknya menghadapi masalah sedimentasi yang cepat di kedua sisi jembatan dan dermaga. Untuk itu, analisis proses sedimentasi di tapak pelabuhan ini dibuat dengan tujuan sebagai bahan referensi studi kasus. Data citra satelit resolusi tinggi menunjukan bahwa luasan sedimentasi di tapak pelabuhan ini sudah mendekati 20,000 m2, sedangkan data hidro-oseanografi mensiratkan bahwa bangunan pemecah gelombang di lepas pantai, diduga membangkitkan difraksi gelombang laut dan arus sepanjang pantai sekaligus sebagai perangkap sedimen membentuk tembolo.

This work aimed to synthesize MnFe2O4 nanoparticles using the coprecipitation method. Manganese chloride dihydrate (MnCl2.4H2O) and iron sand from South Cianjur, Indonesia, were used as a precursor for MnFe2O4 nanoparticle synthesis. The iron sand elements and compounds were tested using X-Ray Fluorescence (XRF). MnFe2O4 nanoparticle was characterized using X-Ray Diffraction (XRD), Scanning Electron Microscope-Energy Dispersive X-Ray (SEM-EDX), and Vector Network Analyzer (VNA). The X-Ray Fluorescence test result showed that 70.54% of South Cianjur contained iron sand. The SEM test result showed that the nanoparticles have an average size of 73.75 nm with a round shape, which was attributed to the agglomeration process. The EDX test result showed that the synthesized nanoparticle contained only Mn, Fe, and O elements without contaminants. The XRD test result showed that the crystal phase of MnFe2O4 was formed with a crystal size of less than 27 nm. The largest reflection losses in the 11.5 - 12.5 GHz range were found in MnFe2O4 with 1:2 variation, i.e., 35.08 dB. This study found that adding iron sand increases MnFe2O4 microwave absorption.

Fly ash can include toxins from high levels of bottom ash in some circumstances, such as burning of solid waste to generate power (resource recovery facilities or waste-to-energy conversion), and combining fly ash and bottom ash together delivers corresponding quantities of contaminants. Under some conditions, fly ash can be classified as non-hazardous waste, but if it is not blended, it can be classified as hazardous waste. The goal of this research was to find out about the differences between fly and bottom ash, as well as the influence of fly ash on bottom ash in terms of avoiding abrasion. In addition, the study's goal was to see how fly ash affected coconut fiber's resistance to abrasion. This study employed a quantitative technique in which the researcher used primary data sources such as questionnaires and observations, as well as secondary data sources such as prior studies. The findings revealed that fly ash had no effect on bottom ash in terms of avoiding abrasion. Furthermore, it is well known that neither fly ash nor bottom ash are effective against coconut fiber. Fly ash has a coarser texture than bottom ash, according to the findings. The regression test revealed that there was no difference between fly ash and bottom ash, as well as coconut coir, in terms of reducing abrasion
