Aceh Province is the westernmost province of the Indonesian archipelago. Geographically, Aceh is a peninsula area of the island of Sumatra which is directly bordered by the Indian Ocean so that Aceh has several small islands. With this condition, it has the potential to be used as a place for seaweed cultivation. An analysis of environmental conditions is needed to produce good quality seaweed. Examination parameters include pH, temperature, heavy metal content, COD and salinity. Sample examination is carried out based on Standar Nasional Indonesia (SNI) No. 7578.1: 2010 and Decree of the Minister of Environment (KemenLH) No. 51: 2004.

Safety Climate yang tinggi menggambarkan bahwa perusahaan sudah memiliki persepsi yang sama. Sedangkan Safety Climate yang rendah menggambarkan bahwa perusahaan masih memiliki persepsi yang berbeda. Dan perbedaan persepsi di dalam perusahaan menyebabkan terjadinya kecelakaan kerja. Karena kecelakaan kerja berawal dari perilaku tidak aman, dan perilaku tidak aman berawal dari persepsi kerja yang berbeda. Penelitian ini bertujuan untuk mengevaluasi keselamatan kerja di Perusahaan Perkebunan PT XYZ dimana setiap tahunnya masih terjadi kecelakaan kerja. Pengukuran ini dilakukan dengan menggunakan metode The Nordic Occupational Safety Climate Questionnaire (NOSACQ-50) yang terdiri dari 7 dimensi iklim kerja. Berdasarkan hasil uji Mann Whitney dan Kruskal Wallis dinyatakan tidak terdapat perbedaan signifikan Safety Climate di kelompok jabatan, jenis kelamin, umur dan lama bekerja. Sedangkan pada kelompok pendidikan terdapat perbedaan yang signifikan untuk dimensi pemberdayaan keselamatan kerja, sehingga perlu diberikan suatu usulan perbaikan iklim keselamatan untuk meningkatkan iklim keselamatan di perusahaan agar tidak terjadi lagi kecelakaan kerja di tahun beriktunya.The safety climate is a shared perception between company management and workers in dealing with safety-related issues within the company. A high level of safety reflects that companies already have the same perception. While the low work safety climate illustrates that companies still have different perceptions. And differences in perception within the company cause work accidents. Because work accidents stem from unsafe behavior, and unsafe behavior begins with different perceptions of work. The purpose of this research is to evaluate the safety of work at Factory Plant where every year there are work accidents. This measurement is done by using The Nordic Occupational Safety Climate Questionnaire (NOSACQ-50) which consists of 7 working climate dimensions Based on test results Mann Whitney and Kruskal Wallis stated there is no significant difference in work safety climate in the occupational group, sex, age and duration of work. While in the education group there is a significant difference for the dimension of the empowerment of work safety, so it needs to be given a suggestion of improvement of the safety climate to improve the safety climate in the company in order to avoid more work accidents in the next year.","PeriodicalId":11527,"journal":{"name":"Elkawnie","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85024249","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Penelitian ini difokuskan pada S. cumini sebagai salah satu tanaman berkhasiat obat yang sudah mulai diteliti dalam khasiatnya sebagai tanaman yang mengandung senyawa bioaktif. Kehadiran teknologi GCMS ditengah belum adanya database tanaman jamblang merupakan peluang alternatif untuk memperoleh metabolom. Database metabolom pada jamblang penting dimiliki untuk menjaga plasma nutfah dari ekploitasi berlebihan yang menyebabkan kepunahan organisme dan budidaya tanaman tersebut. Dengan adanya penelitian inventarisasi level molekuler senyawa antioksidan yang dikandung tanaman jamblang dapat meningkatkan aktivitas penelitian lanjut pemanfaatan tanaman jamblang yang bisa ditingkatkan dalam skala industri nantinya. Untuk menjawab tujuan penelitian ini dilakukan tahapan penelitian sebagai berikut, pada tahap awal dilakukan isolasi metabolom dari kulit buah tanaman jamblang dengan cara ekstraksi. Tahap kedua adalah metabolome analysis menggunakan GCMS. Keluaran dari penelitian ini adalah diperolehnya data tentang hasil GCMS yang memuat senyawa bioaktif yang terkandung pada kulit buah tanaman jamblang yang akan menjadi landasan pengembangan pemanfaatan kulit buah jamblang sebagai antioksidan alternatif pencegah penyakit degenerasi.

This research is focused on S. cumini as one of the medicinal plants that have been studied in its usefulness as a plant containing the bioactive compound. The presence of GCMS technology amid the absence of Jamblang plant database is an alternative opportunity to obtain metabolome. The metabolome database in jamblang is important to keep the germplasm from excessive exploitation causing the extinction of the organism and the cultivation of the plant. Molecular level inventory of antioxidant compounds contained jamblang plants can increase research activities further utilization of jamblang plants that can be increased in the industrial scale later.
