Abstract

Pencarian senyawa metabolit sekunder dari ekstrak aseton kayu batang tumbuhan Durio oxleyanus Griff telah menghasilkan senyawa steroid androst-1,4-dien-3,7-dion (1) beserta dua senyawa lignan yaitu boehmenan (2) dan boehmenan X (3) dan fraksidin (4). Struktur kimia senyawa hasil isolasi tersebut dielusidasi berdasarkan data spektroskopi dan perbandingan dengan data spektrum yang telah dilaporkan sebelumnya. Kata Kunci: Durio, steroid, lignan, kumarin

Abstract

Penimbunan sampah di TPA Batu Layang, Pontianak, Kalimantan Barat menyebabkan terbentuknya air lindi yang memiliki konsentrasi COD sangat tinggi. Hal tersebut menyebabkan dampak buruk terhadap lingkungan dan kesehatan. Pengolahan air lindi secara sederhana dapat dilakukan menggunakan metode adsorpsi. Penelitian ini bertujuan untuk mengetahui variasi waktu kontak, massa adsorben, dan kecepatan pengadukan optimum terhadap efisiensi adsorpsi. Karakterisasi menggunakan FTIR terhadap adsorben cangkang kerang ale-ale menunjukan adanya puncak pada bilangan gelombang 1452 cm-1, 852 cm-1, dan 716 cm-1 yang menandakan keberadaan gugus C-O. Pengukuran konsentrasi COD pada penelitian ini dilakukan secara titrasi permanganometri. Adsorpsi keadaan optimum diperoleh pada massa 4,5 g dengan kecepatan pengadukan 200 rpm selama 240 menit yang dapat menurunkan konsentrasi COD pada air lindi dari 1131,28 mg/L menjadi 456,94 mg/L dengan efisiensi adsorpsi sebesar 59,61%. Adsorpsi dilakukan kembali pada keadaan optimum mampu menurunkan konsentrasi COD pada air lindi dibawah baku mutu menjadi 288,35 mg/L dengan efisiensi adsorpsi sebesar 36,89%.

Abstract

A workshop on the use of supporting applications for the publication of scientific papers has been carried out for Chemistry subject teachers. This activity is in collaboration with the Chemistry Subject Teachers' Conference (MGMP) of Kubu Raya Senior High Schools. This activity aims to utilize the application for compiling bibliographies and checking the similarity of scientific papers to facilitate the writing and publication of scientific papers. The method of implementing the Community Service (PKM) program is through: structural, participatory and instructional approaches; demonstration; practice and mentoring, and evaluation. The results obtained in the form of implementing a one-day workshop activity by presenting research method materials, library search tips and utilization of the Mendeley application, plagiarism checking applications and tips for avoiding plagiarism.The workshop was conducted in the form of a presentation and direct practice of using the application. In addition to being accompanied by the presenters, participants are also accompanied by instructors who have been prepared by the committee so that the activity can run smoothly. In order to increase the interest and attention of participants to participate in the activity, the organizing committee provides door prizes for participants who ask and answer quizzes from the presenters. This method can also be used as an evaluation of the level of understanding of participants in addition to the evaluation in the form of questionnaires distributed after the activity to measure the success of this PKM activity. Based on the questionnaires distributed, participants thought that this activity was very helpful in compiling scientific papers so that it was very useful for participants. Most participants considered that the facilities and training time were in accordance with those conveyed by the presenters who were in accordance with their fields. Overall, it can be concluded that the objectives of implementing this PKM have been achieved.
