Abstract

Berbagai macam tumbuhan obat telah lama digunakan oleh para pengobat tradisional (battra) di beberapa etnis di Sulawesi Selatan untuk mengobati berbagai penyakit termasuk kanker. Penelitian ini dimaksudkan untuk memberikan bukti ilmiah penggunaan tumbuhan obat yang biasa terdapat dalam ramuan obat tradisional untuk pengobatan kanker pada etnis di Sulawesi Selatan. Tahap awal penelitian dilakukan melalui pengujian mutu simplisia dan skrining aktivitas sitotoksik dari 11 tumbuhan obat terpilih yaitu Bambang epa (Cleome viscosa), Barrang-barrang (Drynaria quercifolia (L) J.Sm), Sereh dapur (Andropogun citratus L), Bu’ne (Antidesma bunius L.), Caleo (Jatropa curcas L.), Cambarinono, Korrong-korrong (Borreria ocymoides (Burm.F).CD), Minceng (Tithonia grandiflora (Hemsl.) A.Gay), Pelleng (Aleurites moluccanus L.), Pucuk Merah (Euphatorium triplinerve L) dan Porrok tongko menggunakan cell line kanker payudara yaitu MCF-7 dan T47D dengan metode MTT. Hasil skrining sitotoksik menunjukkan bahwa ekstrak daun minceng yang paling aktif dengan nilai IC50 sebesar 59,622 µg/ml untuk MCF-7 dan 35,313 µg/ml untuk T47D. Ekstrak Etanol daun Minceng kemudian dipartisi dengan etil asetat dan diuji kembali aktivitas sitotoksiknya. Hasil pengujian menunjukkan bahwa fraksi yang larut etil asetat lebih aktif dibanding fraksi yang tidak larut etil asetat dengan nilai IC50 sebesar 13,474 µg/ml pada MCF-7 dan 7,203 µg/ml pada T47D. Isolasi komponen kimia fraksi larut etil asetat dengan metode kromatografi cair vakum (KCV) diperoleh 7 fraksi, yaitu fraksi A, B, C, D, E, F dan G, dimana fraksi D yang paling aktif dengan nilai IC50sebesar 3,636 µg/ml pada MCF-7 dan 2,103 µg/ml pada T47D. Hasil identifikasi komponen kimia secara kromatografi lapis tipis menunjukkan bahwa fraksi D mengandung senyawa terpenoid. Berdasarkan hasil tersebut maka diduga senyawa aktif terhadap cell line MCF-7 dan T47D dari  daun minceng adalah senyawa golongan terpenoid.

The child's growth and development process is influenced by internal and external factors. Giving gadgets to children is an external factor that is supported by socio-economics and parental parenting. Gadgets have a direct impact on children's spoken language development and social independence. (Deddy et.al, 2020). A gadget is a small electronic device that has a special function. Fromdaytodaygadgets always appear to provide the latest technology that makes human life more practical. Technology clearly influences children's development. Because a technological device is averyeffective learning medium. Gadgets have various interesting, varied, interactive and flexible features and applications that add to the appeal for everyone, both among the elderly, young, teenagers and even children. Gadgets have many benefits in human life if they are used properly and correctly, but gadged also has a negative impact on humans, especially for the development of children if used without supervision and direction from parents. Knowledge about the dangers of using devices is very important for parents. The mother's attitude towards using gadgets is one of the factors that can influence behavior. A good attitude towards using gadgets does not guarantee a good attitude in giving gadgets to children (Warsiyah, 2020). Parents' lack of understanding in giving gadgets to early childhood has a big impact on their social-emotional behavior. The purpose of this study is to visualize the impact of gadget use on children's behavior and find out the types of aggressive behaviorthat arise in early childhood due to excessive gadget use.   Abstrak Proses tumbuh kembang anak di pengaruhi oleh factor internal dan ekternal. Penggunan gawai merupakan salah satu factor eksternal yang di dukung oleh social ekonomi dan pola asuh orang tua. Gedget mempunyai dampak langsung terhadap lisan dan kemandirian social anak ( deddy et.al,2020). Gadget adalah sebuah perangkat elektronik kecil yang memiliki fungsi khusus dari hari ke hari gadget selalu muncul dengan menyajikan teknologi terbaru yang membuat hidup manusia menjadi lebih praktis. teknologi jelas mempengaruhi perkembangan anak. Karena sebuah perangkat teknologi merupakan media pembelajaran yang sangat efektif. Gadget memiliki berbagai fitur dan aplikasi menarik, bervariasi, interaktif dan fleksibel sehingga menambah daya  tarik  bagi setiap  orang,  baik dari kalangan lansia, muda, remaja bahkan anak – anak. Gadget memiliki banyak manfaat dalam kehidupan manusia jika digunakan dengan baik dan tepat, tetapi gadget juga memberikan dampak negative bagi manusia khususnya bagi perkembangan anak jika digunakan tanpa pengawasan dan pengarahan dari orang tua. Pengetahuan tentang bahaya penggunaan gadget sangat penting bagi orang tua, adapun sikap ibu terhadap pengunaan gadget adalah salah satu factor yang mempengaruhi perilaku. Sikap yang baik terhadap penggunaan gadget tidak menjamin mempunyai sikap yang baik dalam memberikan gadget terhadap anak.Kurangnya  pemahaman  orang  tua  dalam  pemberian gadget kepada  anak  usia  dini  memberikan dampak  besar  dalam  sosial-emosionalnya.  Tujuan  dari  penelitian  ini  adalah  memvisualisasikan dampak  dari  penggunaan gadget terhadap  perilaku  anak  serta  mengetahui  jenis  perilaku  agresif yang  muncul  pada  anak  usia  dini yaitu  dampak penggunaan gadget yang melampau  batas.
