Lead Poisoning in Gulf of Youtefa, Jayapura, Papua

Background: Lead is a cumulative toxicant that affects multiple body systems and is particularly harmful to young children. Its widespread use has resulted in extensive environmental contamination, human exposure and significant public health problems in many parts of the world. Young children are particularly vulnerable to the toxic effects of lead and can suffer profound and permanent adverse health effects, particularly affecting the development of the brain and nervous system. This study aimed to investigate lead poisoning in Gulf of Youtefa, Jayapura, Papua, particullary it aimed to estimate lead level in water, fish, and shell in the Gulf of Youtefa. Subjects and Method: This was a descriptive cross sectional study conducted in Gulf of Youtefa, Jayapura, Papua. A sample of 75 community members living adjacent to Gulf of Youtefa were selected for this study. In addition, samples of water, fish, and shell were taken from 12 stations in the Gulf of Youtefa. The dependent variable was lead level. Lead poisoning in human subjects was measured from urine sample by Liquid Chromatography Mass Spectrophotometry Detector. Samples of water, fish, and shell were measured by Inductively coupled plasma Thermo IRIS Interepid II. Results: All study subjects showed corpoporphyrin level ≥20 μg/dL indicating lead poisoned, consisting of 57 (76%) females and 18 (24%) males. Out of 57 females, 18 (31.5%) were at reproductive age (20-35 years old), 29 (68.5%) females were ≥35 years old. Mean lead level in water was 0.0265 indicating lead polluted since it exceeded ≥0.008 mg/L. Lead level in fish was 2.16 mg/kg indicating lead polluted since it exceeded ≥0.3 mg/kg. Lead level in the shell was 0.57 mg/kg indicating lead polluted since it exceeded ≥0.3 mg/kg. Conclusion: All study subjects are lead poisoned. Twelve water stations are lead polluted. Fish and shell are also lead polluted

The Use of Marine Sand in Bituminous Mixer

Over the past decade, dramatic increasing in truck traffic, heavier axle loads, various environmental impacts and higher tire pressure had contributed to severe pavement distortions. In Malaysia, permanent deformation (creep deformation) is a continuously pavement distortion problems which caused by effect of temperature, successive stresses, excessive high bitumen content from improper mix design and insufficient compaction during roadway construction. In bituminous mix, fine aggregate's recent trend is using mining sand. Comparison in term of performance towards creep deformation between marine sand and mining sand as fine aggregate are key purpose for the study. For experiments, aggregate gradation are done for coarse aggregate; granite, fine aggregate; marine sand and mining sand as well as filler; ordinary Portland cement. It is to determine the percentages of material used for making Marshall Mix sample. After conducting Marshall Mix design, stability tests is conducted upon each of sample to determine the optimum bitumen content by plotting graph of stability, density and void in mineral aggregate versus binder content. Dynamic creep test is performed to compare the performance of both samples. The result revealed that marine sand reaching stages of failures is twice as much compared with mining sand. It proves that usage of marine sand in bituminous mix increased its resistance towards permanent deformation (creep deformation)

Analisis Performansi Beberapa Wireless Access Point Tipe N Sebagai Media Transmisi Video Streaming

Wireless merupakan media dalam jaringan untuk mentransmisikan data baik berupa teks, audio, maupun video. Generasi wireless berdasarkan protokol standar IEEE 802.11 sampai saat ini telah sampai pada standar IEEE 802.11n, yang sebelumnya menggunakan standar IEEE 802.11g. Data berupa video yang di streaming merupakan data yang membutuhkan piranti wireless dengan performa yang baik. Analisis performansi wireless access point tipe n atau standar IEEE 802.11n digunakan untuk mengetahui bagaimana performa wifi dalam mentransmisikan video streaming. Piranti aplikasi VLC digunakan untuk streaming video dari server ke client. Video dengan format MP4 dan MKV codec h264 kualitas HD dan Full HD digunakan untuk menguji piranti wireless standar IEEE 802.11n. Paket-paket data dari client menuju ke sever di capture menggunakan aplikasi Wireshark. Hasil analisis pengujian menunjukkan bahwa kemampuan wireless access point dengan protokol standar IEEE 802.11n dalam mentransmisikan data berupa video streaming dengan kualitas HD dan Full HD hanya mampu menangani transmisi data tidak lebih dari empat client. Lebih dari empat client, keluaran video pada client tidak nyaman untuk dilihat. Berdasarkan pengujian, 4 buah wifi yang diuji, ubiquiti power AP N mempunyai performa paling baik

Immigrants’ Leisure Participation and Acculturative Stress Management: The Mediating Effect of Community Embeddedness

The increasing trend of migration has driven studies from multiple perspectives including the conceptual lens of their mobility and professional activities Another important dimension of immigrants settlement is the role of leisure participation One issue in immigrants settlement is acculturative stress an issue related to the difficulties immigrants face in their adjustment to the lifestyle of their host country This paper explores the role of leisure participation by investigating a mediating effect of community embeddedness which assists immigrants to manage acculturative stress Community embeddedness enables immigrants to adjust and develop emotional and functional connections to their new community and fosters their social integration This mediator is likely to be related to leisure participation Mediated regression analysis confirmed that leisure participation lessened two components of acculturative stress immigrants not feeling at home and perceived discrimination when mediated by community embeddedness Immigrants leisure participation also had a positive significant direct relationship with community embeddedness suggesting that encouraging immigrants to participate in leisure activities is one way to build their sense of belonging in their new local community These results suggest a means for future research to explain how leisure participation may assist immigrants to adjust to their new location Such a framework has implications for leisure industry managemen

BERALIHNYA HAK MILIK ATAS GADAI TELPON SELULER DARI PEMILIK KEPADA PENERIMA GADAI (SUATU PENELITIAN DI KECAMATAN SUKA MAKMUR ACEH BESAR)

ABSTRAKHASMI YUSUF,BERALIHNYA HAK MILIK GADAI TELPON SELULER DARI PEMILIK KEPADA PENERIMA GADAI(Suatu Penelitian di Kecamatan Suka Makmur Aceh BesarFakultas Hukum Universitas Syiah Kuala)(vi, 62).pp.bibl(EKA KURNIASARI, S.H.,M.H., LLM)Penerima gadai atau kreditur tidak diperkenankan untuk memiliki atau menjadi pemilik atas benda yang digadaikan seperti yang diatur dalam Pasal 1154 KUH perdata yang menyatakan bahwa: apabila siberutang atau sipemberi gadai tidak memenuhi kewajiban-kewajibannya, maka tidak diperkenankan siberpiutang memiliki barang yang digadaikan. Segala janji yang bertentangan dengan ini adalah batal. Namun kenyataannya banyak sipenerima gadai di Kecamatan Suka Makmur Aceh Besar menjadikan barang gadai menjadi hak miliknya setelah jatuh tempo.Tujuan penelitian ini untuk menjelaskan pelaksanaan perjanjian gadai telpon seluler yang dilakukan dimasyarakat Suka Makmur Aceh Besar, faktor penyebab para pihak mengalihkan hak kepemilikan atas objek gadai dan akibat hukum dari beralihnya menjadi hak milik.Pengumpulan data dengan melakukan penelitian kepustakaan yaitu memperoleh data sekunder dengan cara mempelajari literatur dan peraturan perundang-undangan yang berlaku dan sesuai dengan penelitian lapangan yaitu untuk memperoleh data primer melalui wawancara responden dan informan.Berdasarkan hasil penelitian diketahui bahwa gadai telepon seluler yang disepakati oleh kedua belah pihak dilakukan secara lisan dimana hak sipenerima gadai memberikan uang pinjaman atas telepon seluler sebagai barang yang digadaikan dan kewajibannya menjaga dan menguasai telepon seluler yang menjadi barang gadai selama waktu tertentu sedangkan sipemberi gadai mempunyai hak yaitu menerima sejumlah uang pinjaman dan berkewajiban melunasi pinjaman hutang sesuai jangka waktu tertentu. Namun dalam kenyataannya sipenerima gadai menjadikan barang gadai tersebut menjadi miliknya dengan alasan sipemberi gadai telah jatuh tempo.Disarankan kepada masyarakat kecamatan Suka Makmur agar tidak lagi melakukan gadai atau perjanjian utang-piutang secara lisan atau tidak tertulis tanpa mengindahkan ketentuan yang diatur dalam Kitab Undang-Undang Hukum Perdata sehingga dapat menimbul sengketa antara kedua pihak
