THE EXISTENCE OF PLASTIC WASTE MANAGEMENT IN THE SEA ENVIRONMENT SEEN FROM CHEMICAL SCIENCE ANGLE

Plastic waste from year to year in the marine environment continues to increase. This is due to its wide application and its resistance to degradation making it difficult or impossible to decompose. Plastic waste has been found in various sizes and accumulated in the body of marine life. The existence of plastic waste in the body of the marine biota even causes death. This review discusses the latest advances in research and development of methods for handling plastic waste in the marine environment

Hubungan Kecanduan Online Game Mobile Legend dengan Penyesuaian Sosial pada Remaja

Tujuan penelitian ini adalah untuk mengetahui hubungan kecanduan online game mobile legend dengan penyesuaian sosial pada remaja. Pengambilan sampel dalam penelitian ini menggunakan teknik purposive sampling dengan jumlah partisipan sebanyak 69 orang. Metode pengumpulan data pada variabel kecanduan game online menggunakan skala game addiction tedency yang dikembangkan oleh Chen dan Chang (2008) dan variabel penyesuaian sosial menggunakan skala social adjustment scale yang dikembangkan oleh Cooper, Osborn, Gath dan Feggetter (1982). Teknik analisa data menggunakan Pearson. Hasil yang diperoleh adalah r = - 0,835 dengan sig. 1-tailed = 0.000 (p < 0,05), yang berarti terdapat hubungan negatif signifikan antara kecanduan online game mobile legend terhadap penyesuaian sosial pada remaja

Analisis Optimalisasi Penyusunan Laporan Kinerja Melalui Standar Pelayanan Publik (Lingkup Pemerintahan) Di Sekretariat Daerah Provinsi Bengkulu

The main issue in this research is the low standard of public services at the Bengkulu Provincial Secretariat. This is because the service standards for delivering data in the preparation of performance reports to the Provincial Government are currently not technically structured and do not have special regulations, resulting in the non-optimal preparation of performance reports that can describe real conditions that occur at the time such as the absence of service standards in standard form (information/administrative requirements) in the submission of performance report data. The research method uses descriptive qualitative analysis with SWOT through observation and interviews. The results of the study prove that the most appropriate optimization of public services to improve performance reporting is to carry out a communication strategy, and the achievement of success has been seen from the existence of standard service standards. It is hoped that with this research, the government can improve the development of human resources through a high attitude and work spirit that is oriented to the interests of the community, nation and state and has responsibility with the work environment and organization

Waltherione C and cleomiscosin from Melochia umbellata var. Degrabrata K. (Malvaceae), biosynthetic and chemotaxonomic significance

Waltherione C, a 4-quinolinone secondary metabolite, and cleomiscosin have been isolated from Melochia umbellata (Malvaceae).A biosynthetic scheme incorporating the unique 4-pyridones and 4-quinolones isolated from Melochia and Waltheria spp. has been proposed.Waltherione C has an IC50 against P-388 murine leukaemia cells of 0.26 ??g/mL

Analysis of Essential Minerals (Crhomium, Zinc and Mangan) and Test Of Bio-Physical Chemistry Honey From Kindang District, Bulukumba

Honey is a sweet liquid that comes from the nectar of plants that are processed by bee. The composition of minerals in honey is an important factor in determining the quality of honey because it can affect the properties of bio-chemical physics honey. This research investigated the essential minerals concentrattion (Cr, Zn, and Mn), as well as the properties of bio-chemical physics. Three samples were collected from obtained from different location in the district Kindang is, Kindang, Pattallassang and Oro Gading. Honey samples were analyzed for essential micro mineral Chromium, Zinc and Manganese by using instrument ICP-OES and also analyzed for common bio-physicochemical parameters like moisture content, acidity, ash, pH, conductivity, protein, fat, carbohydrate and calorie. Ranged concentration manganese content of honey from 0.05 to 0.07 mg/mL0,05-0,07 mg/mL and concentration of chromium ???0,1 ng/mL-0.22 mg/mL, whereas the concentration of zinc is below the limit detection tool that is ???0,1 ng/mL. The average value of the quality of honey Kindang districts is 19.69% water content, ash content of 0.26%; DHL 0.36 mS/cm; 22.06 acidity meq/kg; pH 4.43; protein of 7.19% (w/w); 0.1301% fat. Total carbohydrate is 72.55%; calories 320.3101 cal; and energy 1340.2289 KJ. The results of this study indicate that manganese has the highest concentration in all samples of honey and showed tah hhoney from Kindang district have the a good quality according to national and international standar of hone

Sistem Informasi Kearsipan Data Pengabdian Masyarakat Program Studi Pendidikan Bahasa Inggris UAD

Sistem Informasi kearsipan data merupakan faktor yang sangat penting di dalam instansi, terutama di dalam Prodi Pendidikan Bahasa Inggris Universitas Ahmad Dahlan yang menggunakan Sistem informasi kearsipan data sebagai pengolah data pengabdian masyarakat. Sistem informasi kearsipan data digunakan untuk mengumpulkan data pengabdian masyarakat dan menyediakan informasi. Data dan informasi yang diperoleh suatu instansi terus-menerus bertambah banyak sehingga memerlukan database dosen untuk pengabdian masyarakat. Karena sistem infromasi kearsipan data yang sekarang digunakan oleh Prodi Studi Pendidikan Bahasa Inggris Universitas Ahmad Dahlan belum mampu menampung banyak data dosen untuk pengabdian masyarakat. Selain itu, sistem informasi kearsipan data yang digunakan sekarang juga masih belum efektif dan perlu pembaharuan terutama untuk fitur dan tampila

VOLATILE COMPOUNDS’ CHARACTERIZATION OF N-HEXANE EXTRACTS OF TERASA’S FOREST HONEY

This study aims to identify volatile compounds that are characteristic of the honey of Terasa village of Sinjai regency of South Sulawesi, volatile honey extracted with n-hexane solvent then identified by Gas Chromatography Mass Spectroscopy (GCMS) method. The results obtained 59 volatile compounds derived from honey are grouped into compounds namely hydrocarbons, aldehydes, ketones, alcohols, esters, bensenoid and carboxylic acids. Based on comparative results with other honey regions it is known that volatile compounds that become characteristic of honey Terasa village that is compound Tetrasilaoktan

COMPARISON OF TWO BACKGROUNDS ON 14C ACTIVITY MEASUREMENT WITH LSC (LIQUID SCINTILLATION COUNTING)

Comparison of the two types of background on 14C activity measurement has been carried out. This study aims to determine a better background for 14C activity measurement using the LSC (Liquid Scintillation Counting) method. The background used consists of two, namely background I and background II. Background I is a marble solution that has been absorbed using 30% DEA. Background II is a 30% DEA solution. Activity measurement of 14C was carried out using Hidex 300 SL liquid scintillation counter (LSC). Activity 14C background I is 99,389 DPM. While Activity 14C background II is 101,178 DPM. This shows that the background that is better used for measuring Activity 14C is background I, which is a marble solution that has been absorbed using DE
