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

Abstract

ABSTRAKInformasi banjir yang lengkap dan akurat dibutuhkan untuk melakukan kegiatan mitigasi bencana dan evakuasi yang cepat. Informasi banjir dalam penanggulangan bencana umumnya meliputi lokasi spatio-temporal banjir, kedalaman banjir, kerentanan, lokasi beresiko serta zona aman. Hal ini dibutuhkan oleh kabupaten Jember yang memiliki beberapa desa rawan banjir hingga wilayah pesisir. Google Earth Engine (GEE) merupakan salah satu alat penginderaan jauh yang dapat digunakan untuk menghasilkan sebuah peta banjir dengan cakupan spasial dan temporal yang baik. GEE melakukan pemrosesan data secara parallel pada infrastruktur komputasi Google sehingga diperoleh efisiensi pemrosesan data dengan menggunakan data spasial batas administrasi desa di Kabupaten Jember, data citra satelit Sentinel-1 SAR dan data citra satelit DEMNAS yang telah dipotong sesuai batas kabupaten Jember. Hasil yang diperoleh adalah terdapat wilayah pesisir yang rawan banjir yaitu desa Sumberejo dan sebagian desa puger karena memiliki kelerengan yang rendah dan memiliki Daerah Aliran Sungai (DAS) dari hulu ke hilir. Wilayah pesisir yang lain termasuk Zona Aman Banjir karena sebagian wilayah memiliki kelerengan yang tinggi dan sebagian wilayah lainnya merupakan wilayah kelerengan rendah namun tidak memiliki DAS.Kata Kunci: GEE, Zona aman banjir, wilayah pesisir, JemberABSTRACTComplete and accurate flood information is needed to disaster mitigation and rapid evacuation activities. Flood information in disaster management generally includes flood spatio-temporal locations, flood depths, vulnerabilities, risk locations and safe zones. This is needed by Jember district, which has several flood-prone villages to coastal areas. Google Earth Engine (GEE) is a remote sensing tool that can be used to produce a flood map with good spatial and temporal coverage. GEE performs parallel data processing on Google's computing infrastructure so that data processing efficiency is obtained by using spatial data on village administrative boundaries in Jember Regency, Sentinel-1 SAR satellite image data and DEMNAS satellite image data that has been cut to the Jember district boundary. The results obtained are that there are coastal areas that are prone to flooding, namely Sumberejo village and some Puger villages because they have low slopes and have a watershed (DAS) from upstream to downstream. Other coastal areas are included in the Flood Safe Zone because some areas have high slopes and other areas are low slope areas but do not have watersheds.Keywords: GEE, flood safe zone, coastal area, Jember

Abstract

ABSTRAKIkan merupakan salah satu bahan pangan yang masuk dalam golongan bahan yang mudah rusak (Perishable food), karena di dalam daging ikan banyak terkandung air dan protein yang cukup tinggi, sehingga dapat mempercepat perkembangbiakan mikroorganisme apabila tidak ditangani dengan benar. Penelitian ini dilaksanakan di Balai Pengujian Mutu Hasil Perikanan (BPMHP) Semarang dari tanggal 5 Januari sampai 5 Februari 2022 dengan tujuan mengetahui mutu mikrobiologis pada produk hasil perikanan berupa udang beku dan rajungan pasteurisasi dalam kaleng. Parameter uji yang dilakukan terdiri atas uji total mikroba, uji E.coli dan uji Salmonella pada udang beku dan rajungan pasteurisasi dalam kaleng. Hasil penelitian menunjukan pada udang beku memiliki nilai ALT sebesar 131,36 x 102 kol/gram E.coli 3 APM/gram, Salmonella negatif dan masih memenuhi standar mutu mikrobiologi SNI 2705: 2014. Hasil uji pada rajungan pasteurisasi dalam kaleng memiliki nilai ALT 2500 kol/gram E.coli 3 APM/gram, Salmonella negatif dan masih memenuhi standar mutu mikrobiologi SNI 6929: 2016. Produk udang beku dan rajungan kaleng pada BPMHP Semarang masih aman untuk dikonsumsi.Kata kunci: Udang beku, Rajungan pasteurisasi dalam kaleng, ALT, E.coli dan SalmonellaABSTRACTFish is one of the foodstuffs that fall into the category of perishable food because fish meat contains a lot of water and high enough protein, so it can accelerate the proliferation of microorganisms if not appropriately handled. This research was carried out at the Fishery Product Quality Testing Center (BPMHP) Semarang from January 5 to February 5, 2022, to know the microbiological quality of fishery products in the form of frozen shrimp and pasteurized crabs in cans. The test parameters consisted of a comprehensive microbial test, an E.coli test and a Salmonella test on frozen shrimp and canned crab. The result showed that ALT value of frozen shrimp was 131.36 x 102 col/gram, E.coli 3 APM/gram, Salmonella was negative and still meets the microbiological quality standard of SNI 2705: 2014. The test results on canned crab have ALT value 2500 col/gram E.coli 3 APM/gram, Salmonella was negative and still meets the microbiological quality standard of SNI 6929: 2016. Frozen shrimp and canned crab products at BPMHP Semarang were still safe for consumption.Keywords: Frozen shrimp, canned crab, ALT, E.coli and Salmonella
