Abstract

Pineapple is a fruit that contains many nutrients so it is good for consumption. To consume pineapple, it takes a long time to peel the skin, thus encouraging innovation to sell fresh pineapple in the form of sliced pineapple. Pineapple that is peeled more quickly loses quality. This can be prevented with edible coating of aloe vera. This research was conducted to determine the effect of aloe vera edible coating with the addition of CMC and glycerol, on the moisture content, weight loss, and organoleptic (color, texture, aroma, taste) of sliced pineapple. This research was a true experimental type with pretest-posttest with control group design. Variations in concentration of CMC (1%, 1.5%) and glycerol (0.5%, 1%) and were replicated 4 times so that there were 24 samples. Observational data including moisture content, weight loss, and organoleptic (color, texture, aroma, taste) were analyzed using the One Way ANOVA test. Until the 9th day of storage, the smallest decrease in water content was found in the G2C2 treatment, which was 84.04%. The smallest increase in weight loss was also found in the G2C2 treatment, which was 11.11%. The highest average organoleptic score on the parameters of color, aroma, texture, and taste was the G2C2 treatment. The provision of aloe vera edible coating on pineapple affects the water content, weight loss and organoleptic properties including color, aroma, texture and taste. The addition of CMC and glycerol concentrations affected the water content, weight loss, color, aroma, and texture but did not affect the taste of pineapple during storage. To improve the results of this study, it is necessary to carry out further research by examining the effect of giving aloe vera edible coating with the addition of CMC and glycerol on total dissolved solids and pH.Keywords: edible coating; Aloe vera; pineapple ABSTRAK Nanas merupakan buah yang mengandung banyak nutrisi sehingga baik dikonsumsi. Untuk mengonsumsi nanas, memerlukan waktu lama dalam pengupasan kulitnya, sehingga mendorong inovasi untuk menjual nanas segar dalam bentuk nanas potong. Nanas yang dikupas lebih cepat mengalami penurunan mutu. Hal tersebut dapat dicegah dengan edible coating dari lidah buaya. Penelitian ini dilakukan untuk mengetahui pengaruh pemberian edible coating lidah buaya dengan penambahan CMC dan gliserol, terhadap kadar air, susut bobot, dan organoleptik (warna, tekstur, aroma, rasa) nanas potong. Penelitian ini berjenis eksperimen murni dengan pretest-posttest with control group design. Variasi konsentrasi CMC (1%, 1,5%) dan gliserol (0,5%, 1%) dan dilakukan replikasi sebanyak 4 kali sehingga berjumlah 24 sampel. Data hasil pengamatan meliputi kadar air, susut bobot, dan organoleptik (warna, tekstur, aroma, rasa) dianalisis menggunakan uji One Way ANOVA. Hingga penyimpanan hari ke 9, penurunan kadar air terkecil terdapat pada perlakuan G2C2 yaitu sebesar 84,04%. Peningkatan susut bobot terkecil juga terdapat pada perlakuan G2C2 yaitu sebesar 11,11%. Rerata skor organoleptik tertinggi pada parameter warna, aroma, tekstur, dan rasa adalah perlakuan G2C2. Pemberian edible coating lidah buaya pada buah nanas berpengaruh terhadap kadar air, susut bobot dan organoleptik meliputi warna, aroma, tekstur dan rasa. Penambahan konsentrasi CMC dan gliserol berpengaruh terhadap kadar air, susut bobot, warna, aroma, dan tekstur namun tidak berpengaruh terhadap rasa buah nanas selama penyimpanan. Untuk menyempurnakan hasil penelitian ini, perlu dilakukan penelitian lanjutan dengan mengkaji pengaruh pemberian edible coating lidah buaya dengan penambahan CMC serta gliserol terhadap total padatan terlarut dan pH.Kata kunci: edible coating; lidah buaya; nanas

Abstract

Pollution of the waters of Kenjeran Beach has resulted in the accumulation of heavy metal lead (Pb) into the body of green mussels, so it is dangerous if consumed in the long term. The purpose of this study was to minimize heavy metals in the body of green mussels by using green coconut water. The design of this research is re-experimental. The sample size was 24 taken at Kenjeran Beach, with variations of 1 hour, 2 hours and 3 hours. The measurement results are compared with the BPOM No. 05 of 2018 concerning the Maximum Limit of Heavy Metal Contamination in Processed Shellfish, which is 0.20 mg/kg. The results showed that the p value = 0.00, so it can be interpreted that green coconut water has the potential to minimize Pb heavy metal green mussel meat. Pb content of green mussel meat was reduced by 0.399 mg/kg; 0.189 mg/kg and 0.67 mg/kg after soaking in green coconut water for 1 hour, 2 hours and 3 hours, respectively. The mean reduction was 37%, 70% and 89% in each treatment. The most effective reduction was in immersion for 3 hours, which was 89%. The use of green coconut water on the market can be an alternative for the community to minimize Pb levels of green mussels by soaking for 3 hours each with an amount of 500 ml.Keywords: green mussels; green coconut water; plumbum ABSTRAK Pencemaran perairan Pantai Kenjeran mengakibatkan terakumulasinya logam berat timbal (Pb) ke dalam tubuh kerang hijau, sehingga berbahaya bila dikonsumsi dalam jangka waktu panjang.

Abstract

Malaria merupakan salah satu fokus kritis masalah kesehatan global. Malaria mengancam sekitar 3,2 miliar orang di seluruh dunia, dan 1,2 miliar orang berisiko tinggi. Setiap tahun terdapat 15 juta kasus malaria dengan 38.000 kematian di Indonesia. Tujuan pengabdian dilakukan untuk meningkatkan pemahaman masyarakat terutama kader dalam membuat kelambu celup insektisida dalam pencegahan dan pengendalian malaria sehingga kasus malaria di kecamatan Gumarang Kabupaten Gumarang dapat menurun. Pengabdian dilakukan melalui penyuluhan dan dilanjutkan dengan melakukan praktek kerja. Melalui pelatihan pembuatan jaring celup, kader desa memperoleh keterampilan teknis dalam membuat dan memelihara jaring celup. Berdasarkan wawancara dengan kader desa binaan, terdapat beberapa keluhan terkait pemilihan kader desa yang umumnya ibu rumah tangga untuk mewakili keikutsertaan dalam pelatihan. Padahal, menurut kader, pekerjaan ibu rumah tangga lebih kompleks, dan tenaga kerjanya tidak lagi mumpuni. Sehingga pemilihan peserta diklat perlu lebih memperhatikan usia, pengetahuan, dan waktu luang peserta, Desa Semarang merupakan salah satu desa di Kecamatan Gemarang yang tahun 2020 juga akan menjadi peserta pelatihan pembuatan kelambu pengabdian masyarakat. Penggunaan kelambu ini merupakan kelambu yang telah dicelupkan ke dalam insektisida yang telah diluncurkan oleh Puskesmas Gemarang sejak tahun 2008 – 2016 dan mendapatkan dana anggaran dari lembaga swadaya masyarakat dan bantuan pemerintah. Hasil kegiatan Durlambu telah memberikan hasil yang positif dan signifikan dalam menurunkan malaria, sehingga diharapkan penggunaan Durlambu akan menjadi kebiasaan untuk menekan malaria. Keberlanjutan penggunaan Durlambu ini diharapkan dapat menjadi alasan kemitraan pengabdian masyarakat antara Poltekkes Kemenkes Surabaya dengan Pemerintah Kabupaten Madiun untuk meningkatkan keterampilan masyarakat dalam membuat jaring pewarna.
