Keberadaan dan Potensi Bakteri Pendegradasi dalam Memperbaiki Pencemaran Tanah Melalui Bioremediasi, 2024

Akumulasi kontaminan seperti logam berat, pestisida, hidrokarbon, dan senyawa organik lainnya dapat mengancam keberlanjutan ekosistem tanah dan kesehatan manusia. Salah satu strategi yang telah diterapkan untuk mengatasi masalah ini adalah bioremediasi, sebuah metode yang menggunakan mikroorganisme untuk mendegradasi kontaminan menjadi bentuk yang kurang berbahaya atau bahkan tidak berbahaya sama sekali secara biologis. Dalam konteks ini, bakteri pendegradasi menjadi fokus utama, karena kemampuannya dalam menghasilkan enzim-enzim khusus yang mampu mengurai senyawa-senyawa kompleks menjadi komponen yang lebih sederhana dan tidak beracun. Walaupun telah banyak penelitian yang dilakukan, namun masih terdapat area penelitian yang belum tersentuh secara menyeluruh yaitu kurangnya pemahaman mendalam tentang interaksi kompleks antara mikroorganisme pendegradasi dengan lingkungan fisik-kimia tempat mereka beroperasi, seperti memahami bagaimana faktor-faktor lingkungan seperti pH tanah, suhu, kelembaban, dan komposisi tanah secara spesifik memengaruhi aktivitas dan efisiensi bakteri pendegradasi dalam kondisi lapangan yang berbeda-beda. Selain itu, perlunya pengembangan metode bioremediasi yang lebih efektif dan efisien untuk mengatasi kompleksitas senyawa-senyawa kimia yang terlibat dalam pencemaran tanah. Beberapa senyawa kontaminan dapat sangat kompleks strukturalnya, yang membuat proses biodegradasi oleh bakteri menjadi lebih lambat dan tidak selalu efisien. Penelitian yang lebih mendalam diperlukan untuk mengidentifikasi bakteri-bakteri pendegradasi yang memiliki kemampuan spesifik untuk mengurai senyawa-senyawa kimia tertentu dengan efektif. Selain itu, pengembangan strategi bioremediasi yang dapat diaplikasikan dalam skala yang lebih besar dan biaya yang lebih terjangkau juga merupakan tantangan penting yang perlu diatasi untuk meningkatkan aplikasi teknologi ini dalam praktik lapangan secara luas.

Considering Distomo as one of the cities-symbols that endured the genocidal violence of National Socialism, as one of the main loci of memory in the Greek historical martyrdom, and as a focal point in the European network of martyr cities, the aforementioned confrontation concerns firstly, the management of the event in reference to identity and historical consciousness, a choice that points towards certain politics of memory in the local society, and, secondly, the moral claim for the recognition of the city’s suffering and the undertaking of responsibilities by the German State. In light of these, the authors approach the issue from a twofold point of view, that is, (a) by analyzing the ways National Socialism, WWII and the mass execution of Distomo’ residents are presented in secondary education history textbooks, and (b) by the interdisciplinary presentation of the local community’s memory politics, which are manifested in the Museum for the Victims of National Socialism and their Mausoleum, around which commemorative and performative rituals are organised on an annual basis. Apart from elevating the role of ceremonies in the memory-making process, this interdisciplinary approach researches the function of education within the official ceremonies, as an important field in the construction of memory.

The problem is how the use of social media as a means of promoting cassava chips in Sampang Regency can increase sales. The output target to be achieved in this study is publishing in ISSN STIA LAN Bandung Journal. This research is a type of quantitative research, viewed from the level of explanation. This research is an associative study with a form of causal relationship. To answer all research objectives, the analysis is used with a Simple Linear Regression Analysis Model and to test the significance used t test. Research data analysis techniques using simple regression. Suggestions for related offices to assist in the develop...

A main objective of the history curriculum for the third grade of primary school in Greece is for children at 8 and 9 years old to familiarize themselves with the basic cultural elements of the origins of Greek, European and global civilization. Ancient Greek myths are taught using references and links to the myths of other peoples and cultures, and by identifying similarities and differences in the interpretation of the world within the framework of a multi-perspective, intercultural approach. Myths also depict the relationship between man and nature. They constitute man's attempt to interpret the physical and social environment. In addition, myths present the relationship between man and the divine in the early stages of cultural evolution, and at the same time provide evidence of the culture of a historical period.
