Kualitas Kesehatan Ekosistem Benua Maritim Indonesia untuk Keberlanjutan Sumber Daya Ikan

Suatu ekosistem terdiri atas tumbuhan, hewan dan mikroorganisme (komunitas biologis) yang berinteraksi satu sama lain, juga dengan lingkungan fisik dan kimia, serta dengan ekosistem sekitar dan atmosfir. Struktur dan berfungsinya ekosistem didukung oleh hasil interaksi dan umpan balik antara organisme dengan lingkungannya (biogeofisik). Pada setiap ekosistem, makhluk hidup membentuk suatu komunitas yang berinteraksi satu sama lain, dengan udara, air dan tanah/sedimen di sekitarnya. Ekosistem-ekosistem ini menyediakan sejumlah besar bahan dan jasa (jasa-jasa ekosistem) yang menopang kehidupan makhluk hidup. Jasa ekosistem adalah “manfaat yang diterima makhluk hidup (termasuk manusia) dari ekosistem, termasuk penyediaan jasa-jasa seperti bahan makanan dan air (provisioning services), pengendalian banjir dan kekeringan, degradasi lahan dan penyakit (regulating services), demikian juga dengan jasa-jasa lainnya seperti pembentukan tanah/sedimen dan siklus nutrien, serta jasa-jasa kebudayaan seperti rekreasi, spiritual, keagamaan dan manfaat non-material lainnya”. Tindakan-tindakan untuk mengkonservasi keanekaragaman hayati ini jelas akan menghasilkan perlindungan dan keberlanjutan dari barang dan jasa yang disediakan ekosistem. Sehingga upaya-upaya memelihara atau menjaga kesehatan ekosistem sangat bermanfaat dalam memperkuat konservasi keanekaragaman hayati. Penelaahan kesehatan ekosistem (ecosystem health) merupakan salah satu prioritas utama saat ini, baik oleh ilmuwan, manajer maupun pemerintahan di seluruh belahan dunia. Tekanan yang menyebabkan menurunnya kondisi kesehatan ekosistem (masa kini dan masa mendatang) termasuk hilangnya habitat alami (misalnya: akibat perubahan pola penggunaan lahan, ekosistem terumbu karang semakin berkurang, rusaknya habitat dasar perairan akibat trawling), perubahan iklim, invasi spesies asing, masuknya nutrien bahan cemar, eksploitasi berlebihan (terhadap stok ikan) serta faktor-faktor lainnya. Dampak utama relatif dari tekanan-tekanan ini sangat berbeda bagi ekosistem-ekosistem yang kita ketahui, namun diyakini akan terus berkontribusi pada penurunan populasi spesies dan hilangnya keanekaragaman hayati pada beberapa dekade mendatang. Terutama apabila tidak diadakan regulasi dan pengontrolan ketat bagi kegiatan-kegiatan manusia yang mendominasi seluruh fungsi-fungsi ekologis. Ekosistem-ekosistem yang didominasi oleh aktivitas manusia, termasuk berbagai sistem biofisik mengalami tekanan sedemikian tingginya hingga mengalami disfungsi, baik pada tingkat regional maupun global. Makalah ini membahas pentingnya memelihara kondisi kesehatan ekosistem utama di Benua Maritim Indonesia (BMI) untuk menjamin keberlanjutan sumberdaya ikan. Kata kunci: kesehatan ekosistem, sumberdaya ikan, BMI.

Implementation of Quality Improvement Tools In Brass Industry To Improve Quality & Enhance Productivity

Significance of quality with increased productivity at an affordable cost is out of question. In this regard, applications of Statistical Quality Tools go a long way not only to improve the quality of a product but also to eliminate the causes, which gave birth to Non – Conforming units. In engineering production units where workforce is unaware to Quality Management system (QMS) it is very difficult to manage production with in acceptable quality standard. Heavy input costs at shrunk/ reduced outputs are no longer sustainable. In most of the production units the rejection of components is never analyzed and resultantly factors causing these high rejection percentages are not rooted out. The focus of study here has been Brass Industry with special emphasis on reducing rejection percentage to a lower possible limit in 70:30 Brass strip and Gilding Metal Claded Steel (GMCS Strip). Initially, data regarding rejection in Brass and GMCS Strip was collected for complete analysis. The process of applying relevant Statistical Quality Tools was started in order to find out the major defects and the root causes of the same. The analysis made so far revealed that existing rejection percentage in Brass and GMCS Strip has been in the range of Fifteen percent (15%) and Twenty one percent (21%) respectively, which is an alarming situation. The ultimate end of the study was to reduce the existing rejection percentage to a range of 8 – 10 % in Brass, and 12 – 14 % in GMCS, and thereby improve the quality, savings, enhance productivity and hence to reduce the wastages.
