THE USE OF SEQUENTIAL EXTRACTION PROCEDURES FOR HEAVY METAL SPECIATION IN SEDIMENT. Metals accumulation in sediments from both natural and anthropogenic sources occurs in the same way, making it difficult to identify and determine the origin of heavy metals present in the sediments. Moreover, the total concentration of metals often does not accurately represent their characteristics and toxicity. In order to overcome the mentioned obstacles, it is necessary to evaluate the environment effect. Single extraction is thus used generally to provide a rapid evaluation of the exchangeable metal fraction in sediments. However, complicated sequential extraction procedures are used to provide more detailed information regarding different metal phase associations.

Lumpur pemboran merupakan salah satu faktor yang memiliki peranan paling penting selama berlangsungnya operasi pengeboran, maka dari itu perlu untuk mengontrol sifat-sifat fisik dari lumpur pemboran agar sesuai dengan spesifikasi yang diharapkan. Lumpur pengeboran mempunyai fungsi penting dalam operasi pengeboran yaitu mengangkat serbur (cutting) ke permukaan, mencegah runtuhnya dinding lubang bor agar suatu kegiatan pemboran dapat berjalan dengan lancar. Pada tugas akhir ini dilakukan analisa pengangkatan cutting pada sumur T trayek 12 ¼". Metode-metode yang digunakan pada penelitian pengangkatan cutting ialah Cutting Carrying Index (CCI) dengan nilai >1, Cutting Transport Ratio (CTR) >50% dan Cutting Capacity Annulus (CCA) <5%. Dengan parameter yang menjadi acuan dalam proses pengangkatan cutting yaitu Plastic Viscosity (PV), Yield Point (YP), Gel strength, Index kelakuan aliran (n), Konstanta Power Law (K), Laju alir (Q), densitas lumpur, densitas cutting, diameter cutting, diameter lubang bor, dan diameter luar pipa bor. Pada Penelitian ini, analisa pengangkatan cutting pada sumur T trayek 12 ¼" dengan metode Cutting Carrying Index (CCI) didapatkan nilai berkisar antara 1,554 - 3,494, metode Cutting Transport Ratio (CTR) didapatkan nilai berkisar antara 86,866% - 95,127% dan pada metode Cutting Capacity Annulus (CCA) 2,940% - 2,974%. Jika dilihat nilai dari ketiga metode yaitu Cutting Carrying Index (CCI), Cutting Transport Ratio (CTR), dan Cutting Capacity Annulus (CCA) telah menunjukkan hasil yang baik sehingga pengangkatan cutting berjalan secara optimal pada sumur T trayek 12 ¼".

Toinaman Hamlet is located on Moa Island, the condition of the hamlet is remote, limited infrastructure, minimal access to basic services and is an isolated hamlet. Most of the residents in this hamlet are very dependent on the weather and natural products to survive. When natural conditions are unfavorable, such as storms, drought or rough seas, their source of livelihood is significantly disrupted. This of course greatly affects the ability of local hamlet communities to be able to meet their nutritional food needs, especially to fulfill their children's nutrition. Fulfilling nutrition for children in rural areas often faces its own challenges, especially related to access to a variety of nutritious foods. Some common problems include limited food ingredients, traditional diets that may lack diversity, and limited knowledge about nutrition. One source of nutritious food that is important for health is beef. Beef is a good source of protein for children because it contains many important nutrients such as iron, zinc and vitamin B12, all of which support their growth and development. The PKM activity carried out is in the form of providing nutritious food in the form of processed beef to the children of Toinaman Hamlet, Moa Island. The aim is to improve the nutrition of the hamlet children, prevent malnutrition and nutritional deficiencies and support the growth and development of the children of Toinaman Hamlet, Moa Island. The food products provided are food products made from beef, namely rendang products

The Law on the Elimination of Domestic Violence Number 23 of 2004 has generated mixed responses among the public. A number of people are unhappy with the regulation, seeing it as an attempt to bring personal problems into the public domain. Although it cannot be denied, the issue of domestic violence is still considered a topic to be avoided in some segments of our society. This is considered a family issue that should not be discussed openly, despite the fact that various types of domestic violence continue to occur, including physical violence, sexual violence, psychological violence and economic violence. Forms of violence in the domestic sphere occur between family members, including violence from husbands against wives, wives against husbands, husbands against children, wives against children, and children against parents. Therefore, it is deemed necessary by the Klis Village Government, Moa Island District, Southwest Maluku Regency to serve as a collaborative initiative in implementing the work program between the 2023 Southwest Maluku PSDKU Unpatti KKN Students and the Klis Village Government. The aim is to hold outreach activities regarding the Elimination of Domestic Violence.
