Abstract

Pentingnya mengetahui kandungan logam nikel (Ni) dalam air laut dan persebarannya disekitaran Teluk Kendari, Sulawesi Tenggara karena kebolehjadian terjadinya pencemaran limbah domestik dan akumulasi sedimentasi di badan perairan yang terbawa melalui aliran sungai dan drainase perkotaan. Penelitian ini menyajikan beberapa korelasi antara aktivitas keramaian masyarakat dengan tingkat kandungan logam Ni disekitaran Teluk Kendari yang dianalisis menggunakan instrumentasi spektroskopi serapan atom (SSA). Penentuan 5 titik lokasi berbeda dipilih berdasarkan banyaknya kegiatan aktivitas masyarakat. Selanjutnya, sampel diambil masing-masing sebanyak 1 Liter sejauh ±100 m dari garis pantai yang selanjutnya dianalisis menggunakan instrument SSA. Hasil penelitian menunjukkan bahwa adanya hubungan aktivitas keramaian kegiatan masyarakat terhadap tingginya kandungan logam Ni yang terakumulasi dalam air laut Teluk Kendari. Kandungan logam Ni yang diperoleh bervariasi berturut-turut T1< T4< T3< T2> T5 yaitu 0,047; 0,052; 0,063; 0,068; 0,073. Berdasarkan baku mutu, standar kandungan Ni dalam air laut sebesar 0,05 mg/L, sehingga pada T2, T3, T4, dan T5 dinyatakan telah melebihi ambang batas. Hal ini disebabkan lokasi tersebut maraknya aktivitas masyarakat sehingga kebolehjadian nilai logam Ni juga meningkat. Berdasarkan hasil penelitian ini memberikan informasi terkini terkait wilayah pencemaran lingkungan akibat akumulasi logam berat dan juga bagi masyarakat agar tidak mengkonsumsi ikan yang diperoleh dari Teluk Kendari.

Abstract

Penelitian ini di lakukan di wilayah Sulawesi Tenggara. Penentuan lokasi penelitian dipilih secara sengaja (purposive sampling)dengan pertimbangan adanya ketimpangan yang terjadi dalam Produk Domestik Regional Bruto Sulawesi Tenggara selama tahun 2015-2020 khususnya pada sektor pertanian berdasarkan data yang bersumber dari Badan Pusat Statistik Sulawesi Tenggara. Sektor pertanian mengalami fluktuasi kontribusi Produk Domestik Regional Bruto menurut lapangan usaha terhadap pertumbuhan ekonomi, sementara Produk Domestik Regional Bruto sektor ini terus meningkat dan kecenderungan aktivitas ekonomi masyarakat masih mendominasi pada sektor pertanian. Sehingga perlu dilakukan kajian yang menyebabkan terjadinya fenomena ini. Tujuan penelitian untuk mengetahui dan mengkaji daya saing komoditi pada sub sektor perikanan. Untuk menjawab komoditi yang memiliki daya saing ekspor digunakan analisis Revealed Comparative Advantage (RCA). Hasil penelitian menunjukkan bahwa komoditi sub sektor perikanan Sulawesi Tenggara berdaya saing kuat untuk ekspor pada komoditi gurita beku, rumput laut dan ikan (cakalang, tuna dan tongkol) dengan rata-rata nilai RCA kurun waktu lima tahun terakhir (2015-2020) masing-masing 24,2 (Gurita Beku), 2,6 (Rumput Laut), dan 2,04 (Ikan cakalang, tuna dan tongkol). Hal ini ditunjukkan pada nilai RCA lebih besar dari satu, daya saing kuat tersebut akan memberikan kontribusi positif terhadap pertumbuhan ekonomi Sulawesi Tenggara. Sedangkan komoditi udang, cumi-cumi dan kerang merupakan komoditi sub sektor perikanan Sulawesi Tenggara yang memiliki daya saing lemah dengan nilai RCA masing-masing lebih kecil dari satu (0,45, 0,18 dan 0,16) kurun waktu 2015-2020.

Abstract

Public nutrition is essential to obtain a healthy and fit body condition, especially during a pandemic like today. The content of vitamins A, C, magnesium, gelatin, phosphorus, and antioxidants in chicken meat can help build the immune system to fight viruses. Besides that, the content of amino acids derived from chicken protein can form antibodies to fight infections. Therefore, raising free-range chickens can be a good business opportunity to fulfill the need for healthy meat from free-range chickens. In addition, it is indicated that the demand for chicken meat in Kendari has yet to be fulfilled, so it must be supplied from other regions. Therefore, raising super free-range chickens can be a promising solution and business opportunity with a maintenance pattern that is not too complicated, where even a not-too-large area of ​​land can be used as a place for its maintenance. Even so, the obstacle free-range chicken breeders face is the slow growth of free-range chickens, which can take 4-6 months to produce 1 kg body weight. But now, this problem can be overcome by the presence of super-free-range chickens or super Javanese chickens, which are the result of crosses between male local native chickens and breeder breeders that have fast growth characteristics. With a maintenance pattern that is not too complicated, where even a not-too-large area of ​​land can be used as a place for its maintenance. The body and flesh still show the type of free-range chicken but with organic care, without drugs, and with organic feed.
