Abstract
Combining thin film deposition with in situ heating electron microscopy allows to understand the thermal stability of complex solid solution nanomaterials. From a CrMnFeCoNi alloy target a thin film with an average thickness of ~10 nm was directly sputtered onto a heating chip for in situ transmission electron microscopy. We investigate the growth process and the thermal stability of the alloy and compare our results with other investigations on bulk alloys or bulk-like films thicker than 100 nm. For the chosen sputtering condition and SiNx substrate, the sputter process leads to the Stranski–Krastanov growth type (i.e., islands forming on the top of a continuous layer). Directly after sputtering, we detect two different phases, namely CoNi-rich nanoscale islands and a continuous CrMnFe-rich layer. In situ annealing of the thin film up to 700°C leads to Ostwald ripening of the islands, which is enhanced in the areas irradiated by the electron beam during heating. Besides Ostwald ripening, the chemical composition of the continuous layer and the islands changed during the heating process. After annealing, the islands are still CoNi-rich, but lower amounts of Fe and Cr are observed and Mn was completely absent. The continuous layer also changed its composition. Co and Ni were removed, and the amount of Cr lowered. These results confirm that the synthesis of a CrMnFeCoNi thin film with an average thickness of ~10 nm can lead to a different morphology, chemical composition, and stability compared to thicker films (>100 nm).

Impact statement
Exploring stability of a complex solid solution thin film by in situ heating transmission electron microscopy is a study of the thermal stability of sputtered complex solid solution thin films with thicknesses of ~10 nm. Complex solid solution materials have a promising electrocatalytic behavior due to the interplay of multi-element active sites. In order to understand their catalytic properties, it is important to identify the different structure-composition-activity correlations. Thus, our investigation helps to clarify and to understand the stability of nanoscale complex solid solution with an average film thickness of ~10 nm.

Produktivitas biomassa dan minyak yang dihasilkan oleh mikroorganisme dapat dipengaruhi oleh beberapa faktor seperti teknik pertumbuhan, teknik pemanenan biomassa dan juga metode ekstraksi yang digunakan. Perbedaan hasil produktivitas minyak juga dapat terjadi akibat adanya perbedaan spesies mikroorganisme yang digunakan. Penelitian ini bertujuan untuk mengetahui pengaruh jenis mikroorganisme yang ditumbuhkan pada media cair dengan kondisi pertumbuhan yang sama terhadap perolehan jumlah biomassa dan yield minyak yang dihasilkan oleh mikroorganisme. Mikroorganisme yang digunakan pada penelitian ini adalah mikroalga dan yeast yang telah diisolasi dari perairan hutan bakau kota Banda Aceh yang telah teridentifikasi secara genetik sebagai T multirudimentale (mikrooalga) dan Rhodotorula mucilaginosa (yeast). Hasil penelitian ini menunjukkan bahwa mikroalga dapat memproduksi biomassa lebih tinggi (8,90 g/L) daripada yeast (4,20 g/L). Mikroalga memiliki densitas optis kultur lebih tinggi dibandingkan yeast. Perolehan tertinggi yield minyak dihasilkan oleh yeast yaitu sebesar 1,70 % sedangkan pada mikroalga 0,45%. Jenis mikroorganisme berpengaruh sangat nyata (≤0,01) pada yield minyak mikroorganisme yang dihasilkan.The Effect Of Isolated Types Microorganism From Mangrove Area In Banda Aceh Toward Biomass And Lipid ProductionAbstract.

Pengaruh Ekstrak Kulit Jengkol dan Umbi Gadung Racun Terhadap Mortalitas Keong Mas (Pomacea canaliculata Lamarck)
Authors: Ikhsan Mohammad , Husni Husni , Rusdy Alfian 
Published: February 2022

Abstrak: Hasil penelitian menunjukkan bahwa kombinasi aplikasi ekstrak kulit jengkol dan ekstrak umbi gadung racun berpengaruh terhadap penghambatan makan, waktu kematian dan mortalitas keong mas. Persentase penghambatan makan tertinggi terdapat pada perlakuan J3G3 rata-rata 3,77%. Aktifitas makan keong mas mengalami penghambatan karena peran senyawa alkaloid pada ekstrak kulit jengkol yang bersifat racun perut bersinergi dengan senyawa HCN yang membuat metabolisme keong mas terganggu. Waktu kematian tertinggi terdapat pada perlakuan J3G3 dengan jumlah kematian 10 ekor. Kecepatan kematian keong mas sangat ditentukan oleh tingginya kandungan senyawa toksik yang terdapat pada berbagai perlakuan konsentrasi ekstrak kulit jengkol dan umbi gadung racun, dimana semakin tinggi kandungan senyawa toksik yang terdapat pada ekstrak kulit jengkol dan umbi gadung racun maka kematian keong mas akan semakin cepat. Mortalitas keong mas tertinggi terdapat pada perlakuan J3G3 yang mencapai 100%. Tingginya mortalitas keong mas dipengaruhi oleh senyawa toksik yang terdapat pada ekstrak kulit jengkol yaitu alkaloid, steroid/triterpenoid, saponin, flavanoid dan tanin bersinergi dengan senyawa toksik yang terdapat pada umbi gadung racun yaitu dioskorin dan asam sianida.The Effect of Jengkol Peel Extract and Gadung Tuber on the Mortality of The Golden Snail (Pomacea canaliculata LamarckAbstract. The results showed that the combination of jengkol peel extract and gadung tuber extract had an effect on feeding inhibition, time of death and mortality of golden snails. The highest percentage of food inhibition was found in the J3G3 treatment, an average of 3.77%. The activity of eating golden snails was hampered because of the role of alkaloid compounds in jengkol skin extract which is a stomach poison in synergy with HCN compounds that interfere with the metabolism of golden snails. The highest time of death was found in the J3G3 treatment with 10 deaths. The speed of death of golden snails is largely determined by the high content of toxic compounds found in various concentrations of extracts of jengkol peel and gadung tubers, where the higher the content of toxic compounds contained in the extracts of jengkol peel and gadung tubers. the faster the death of the golden snail. The highest gold snail mortality was found in the J3G3 treatment which reached 100%. The high mortality of golden snails is influenced by the toxic compounds found in the jengkol peel extract, namely alkaloids, steroids/triterpenoids, saponins, flavonoids and tannins that synergize with toxic compounds found in gadung tubers, namely dioscorin and cyanide acid.
