Abstract

Isolasi dan karakterisasi terpenoid dari fraksi etil asetat ekstrak kulit batang Shorea singkawang telah dilakukan. Senyawa ini diisolasi dengan metode maserasi, kromatografi kolom, dan rekristalisasi serta dikarakterisasi dengan metode spektroskopi. Terpenoid tersebut berupa padatan putih dengan titik leleh 140-142°C dan berdasarkan data GC menunjukkan adanya 1 puncak. Berdasarkan data spektroskopi UV dan IR, senyawa hasil isolasi dalam pelarut metanol menunjukkan serapan maksimum pada panjang gelombang 201 nm dan memiliki gugus –OH, -CH2, -CH3, dan geminal dimetil namun belum diketahui posisi dari gugus-gugus tersebut. Hasil uji antioksidan dengan metode DPPH menunjukkan ekstrak etil asetat memiliki potensi sebagai antioksidan dengan EC50 sebesar 0,075%. Kata kunci : Shorea singkawang, terpenoid, uji antioksidan

Abstract

The earliest stages of cancer detection determine the successful of cancer treatment andtherapy. The existing cancer test or detection methods have been routinely used, but they arelack of sensitivity and specificity that are needed to avoid false positive or negative results. Thegenomic basedtechniques have been applied, although molecular understandings of cancerfar from complete, but few genomic platforms are becoming routine. Application of proteomicsbasedtechniques provide intriguing outcome, which is cancer detection at their earliest stages.Proteomics have exposed a new perspective into the phases of tumorigenesis and depictedmore detailed molecular network scheme, which made important contributions in the discoveryof biomarker of early diagnosis, prognosis and prediction outcome of cancer therapies.The noticeable proteomic platforms to achieve these goals are protein microarray, tissuemicroarray, mass spectrometry-based proteomic, and two-dimensionalgel electrophoresis (2-DE). The application of these techniques will be overviewed, providing a general review ofcurrent proteomic methods in cancer detection and subsequently improvement in prognosisand prediction of cancer therapies.Keywords: proteomics, protein microarrays, mass spectrometry, cancer biomarkerAbstrakDeteksi dini kanker sangat menentukan keberhasilan penanganan dan terapi kanker. Hinggasaat ini, telah banyak jenis metoda deteksi dan uji kanker yang sudah rutin digunakan, akantetapi metoda-metoda tersebut memiliki tingkat sensitifitas dan spesifikasi yang rendah,sehingga sering menyebabkan terjadi kesalahan hasil uji baik secara positif ataupun negatif.Bidang genomik telah banyak digunakan untuk lebih memahami kanker pada level molekuler,meskipun hasil yang diperoleh belum mendalam, akan tetapi beberapa metoda berbasiskangenomik telah mulai rutin digunakan. Bidang pioteomik mulai banyak diaplikasikan untukkeperluan deteksi kankersedini mungkin. Proteomik memberikan perspektif dalam mempelajarifase-fase pembentukan tumor dan juga bisa memberikan gambaran rangkaian molekuler yangterlibat. Hasil ini akan menjadi suatu kosntribusi yang sangat besar untuk mencari biomarkeruntuk diagnosa awal, prognosa dan dan memprediksikan luaran terapiyang muncul.

Abstract

Plastic waste gets special attention to deal with it, but the largest waste in the final disposal site is organic waste, about 60% dominates the amount of existing waste. Organic waste if processed and used for daily life can actually provide additional income if taken seriously. The purpose of this activity is to provide knowledge and skills for female partner organization partners, especially from students who live in West Sumatra, about zero waste so that it can process organic waste into several products that are useful and have economic value on a household scale. The activity methods were directives, counseling/awareness/socialization, training, mentoring and business consulting. The stages of implementation were 1) planning the right activities according to the needs of partners, 2) mentoring webinars, 3) evaluation. Based on the activity that have been carried out, it could be concluded that 1) Partners need assistants to solve the waste problem in Partner households, 2) The zero waste mentoring webinar activity had been carried out online using the zoom application, which was attended by more than 108 the participants who came from students and the public were enthusiastically by three presenters as well as reliable practitioners in their respective fields with the topics of eco enzymes, indigenous microorganisms (IMO), waste - maggot - compost. 3) Participants were very impressed with the zero waste webinar and asked to be followed up on other webinars. 4) The eco enzyme, MOL and compost training activities would be held offline and a visit to Minagot.

Abstract

The Qur'an Education Park (TPQ) and Tahzhul Qur'an House (RTQ) of the Raudhatul Adzkia Jorong Dalam Koto Nagari Koto Tangah, Tilatang Kamang, and District of Agam have been launched since 2015. The students who study here are free of charge. The operational costs of education and the honorarium for educators come from donations from their community and some nomads. However, this contribution is not sufficient for operational costs. The Department of Chemistry's community service team, Andalas University, collaborated with partners to start a business to solve this problem. The business was carried out using vacant land owned by partners for catfish cultivation. Surveys, program socialization and assisting activities were carried out online using virtual media, while Partners carried out the implementation in the field. Activities carried out were pond preparation, the release of catfish seeds, feeding, sorting, maintenance, harvesting, and marketing cultivated catfish. Based on the evaluation, 5000 seedlings from the released catfish developed well. About 99% of catfish typically growth to a large and even size, while the other 1% growth relatively slowly. Harvested catfish were sold for IDR 18,000/kg for wet fish and IDR 100,000/kg for dried fish. This business has been carried out sustainably by partners, and the profits have been used to support the operational costs of TPQ and RTQ Raudhatul Adzkia.
