Abstract

ABSTRAKProduksi garam di desa Padelegan menggunakan metode tradisional yaitu memanfaatkan sinar matahari dalam proses penguapan serta menggunakan bahan baku air laut. Lokasi pengambilan bahan baku berada dekat dengan daratan, hal ini dapat berpotensi bahan baku tercemar oleh limbah pembuangan aktivitas manusia. Limbah daratan berkontribusi dalam pencemaran logam berat, salah satunya timbal (Pb). Tujuan dari penelitian ini yaitu menganalisa kandungan logam berat timbal (Pb) pada 9 titik sampling yang mewakili daerah pantai, transisi antara pantai dengan laut lepas, dan area laut lepas. Metode yang digunakan dalam penelitian ini adalah deskriptif, sedangkan penentuan lokasi penelitian menggunakan metode purposive sampling. Sampel diuji kandungan logam timbal (Pb) menggunakan AAS (Atomic Absorbtion Spectrophotometry). Hasil penelitian menunjukkan kandungan logam berat timbal (Pb) di perairan Padelegan melebihi ambang batas baku mutu air laut yang ditetapkan Keputusan menteri Lingkungan Hidup No 51 tahun 2004, kandungan Pb tertinggi pada titik 7 sebesar 1,0815 mg/l sedangkan kandungan Pb terendah berada pada titik  5 yakni 0,6332 mg/l.Kata Kunci: Bahan baku, garam, timbal, pamekasan, AASABSTRACTSalt production in Padelegan uses traditional methods, utilizing sunlight in the evaporation process and using sea water as raw materials. The location for taking raw materials is close to the mainland, this can have the potential for raw materials to be polluted by waste disposal of human activities. Land waste contributes to heavy metal pollution, one of which is lead (Pb). The purpose of this study was to analyze the heavy metal content of lead (Pb) at 9 sampling points representing the coastal area, the transition between the coast and the high seas, and the high seas area. The method used in this research is descriptive, while the determination of the research location uses purposive sampling method. Samples were tested for lead (Pb) metal content using AAS (Atomic Absorbtion Spectrophotometry). The results showed that the heavy metal content of lead (Pb) in the waters of Padelegan exceeded the seawater quality standard set by the Minister of Environment Decree No. 51 of 2004, the highest Pb content at point 7 was 1.0815 mg/l, while the lowest Pb content was at point 5 is 0.6332 mg/l.Keywords: Raw materials, salt, lead, pamekasan, AAS

ABSTRAKPemijahan ikan merupakan salah satu proses tahapan perkembangbiakan induk ikan jantan dan betina yang yang matang gonad. Pemijahan ikan yang sering dilakukan adalah pemijahan secara semi buatan dan buatan dengan menggunakan hormone sintesis seperti ovaprim maupun mengunakan hormone secara alami yang diproduksi oleh kelenjar hipofisa pada ikan donor. Tujuan penelitian adalah untuk mengetahui pengaruh dosis ekstrak kelenjar hipofisa ikan mas dengan perlakuan dosis 0.5 ml, 1.0 ml, 1.5 ml terhadap derajat pembuahan telur (FR), derajat penetasan (HR), dan kelangsungan hidup (SR) ikan lele sangkuriang. Metode yang digunakan adalah metode eksperimen penyuntikan dosis kelenjar hormone hipofisa ikan mas untuk menganalisis pengaruhnya dalam pemijahan induk ikan lele sangkuriang secara semibuatan. Hasil penelitian terhadap penggunaan dosis kelenjar hipofisa ikan mas untuk pemijahan ikan lele sangkuriang didapat nilai rata-rata derajat pembuahan telur tertinggi pada perlakuan dosis 1.5 ml sebesar 87.1 %, nilai rata-rata derajat penetasan tertinggi pada perlakuan dosis 1.5 ml sebesar 30.7 % dan nilai rata-rata  tingkat kelangsungan hidup tertinggi pada perlakuan dosis 1.5 ml sebesar 97.4 %.

Kamal, Kab. Bangkalan. This research was conducted by purposive sampling method, where bittern samples were taken from the salt ponds of Banyuajuh village, Kec. Kamal by measuring the salinity first. The method of calculating the total value of bacteria using the Total Plate Count (TPC) method and for bacterial identification, heterotroph bacteria were isolated on TSA media. The results of the TPC calculation were obtained in the 10-5 dilution series, namely 416 CFU/mL, while the 10-6 dilution series obtained 157 CFU/mL, and the 10-7 dilution series obtained 114 CFU/mL. While the isolation results obtained 10 isolates. Bittern bacteria. Keywords: Halophilic Bacteria, Salt Laundry Waste (Bittern), Total Plate Count (TPC)

Abstract

ABSTRACTGaram merupakan salah satu komoditas penting dalam dunia industri pangan untuk pemberi rasa asin pada makanan. Konsumsi garam oleh masyarakat dianggap berlebih sehingga rentan menimbulkan penyakit seperti hipertensi. Salah satu faktor yang mem pengaruhi penyakit hipertensi yaitu kelebihan asupan Natrium pada makanan. Penggunaan garam dapur biasa yang berlebihan dapat menyebabkan hipertensi. Berdasarkan hal tersebut untuk mengurangi konsumsi Natrium yang berlebihan pada garam dilakukan penelitian proses produksi garam rendah Natrium. Tujuan dari penelitian ini adalah mengetahui kadar NaCl yang terkandung pada hasil garam yang dihasilkan. Tahapan penelitian meliputi: pengambilan bahan baku air laut, percobaan proses produksi garam sehat rendah Natrium dengan ke-3 perlakuan, pengukuran parameter (kepekatan air laut, ketinggian air, intensitas cahaya dan suhu air), uji kualitas hasil garam serta anilisis pengaruh pengukuran parameter. Hasil penelitian menunjukkan bahwa kadar NaCl yang didapatkan berbeda signifikan antara perlakuan ke-1 kontrol, perlakuan ke-2 dengan penambahan air laut satu kali, dan perlakuan ke-3 dengan penambahan air laut hingga dua kali. Penambahan air laut pada penelitian ini menunjukkan bahwa dapat menurunkan hasil kadar NaCl dan Natrium pada garam yang dihasilkan. dimana hasil kadar NaCl perlakuan ke-1 didapatkan niilai sebesar 90 % , perlakuan ke-2 didapatkan kadar NaCl nilai sebesar 66 % , dan kadar NaCl perlakuan ke-3 didapatkan nilai sebesar 61 % . Hasil penelitian ini dapat menunjukkan bahwa pemberian perlakuan yang berbeda mampu mempengaruhi kandungan kadar NaCl pada garam yang dihasilkan.Kata Kunci: Garam, Natrium , kualitas garamABSTRAKSalt is one of the important commodities in the food industry for giving salty taste to food. Consumption of salt in public is considered too much, so that susceptible cause disease like hypertension. One of the factors that in fluence hypertension is too much sodium in take in food. Using too much regular salt can causing of hypertension. Based on this, to reduce sodium consumption in salt, research is carried out on low -sodium salt production processes. The purpose of this study was to determine the level of NaCl contained was generated of the salt. The research stages include: taking seawater raw materials, experimenting the production process of healthy low-sodium salt with the 3 treatments, measuring parameters (seawater density, water level, light intensity and water temperature), testing the quality of salty ields and analyzing the effect of parameter measurements. Show Generated that the NaCl levels obtained were significantly different between the first treatment control, the second treatment with addition of seawater once, and the third treatment with the addition of seawater up to two times. The addition of sea water in this study shows that it can reduce the results of NaCl and Sodium levels in the resulting salt. Where the results of the NaCl content of the first treatment obtained a value of 90 % , the second treatment obtained a NaCl value of 66 % , and the NaCl content of the third treatment obtained a value of 61 % . The results of this study can indicate that different treatments can affect the content of NaCl levels in the generated salt.Keywords: Salt, Natrium, quality salt
