This research used a completely randomized design (CRD) consisting of 5 treatments and 3 replications. Data were analyzed statistically using ANOVA followed by Duncan's New Multiple Range Test (DNMRT) at 5 % significance level. Treatment in the present research is the addition of aloe vera gel at 0 g; 5 g; 10 g; 15 g; and 20 g. The observations to the result of skin lotion product were organoleptic, physical analysis, chemical analysis, product moisturize test, irritation test, microbiological analysis and antioxidant activity test. The physical analysis which is observed such as viscosity, specific gravity, emulsion stability and chemical analysis which is observed such as pH value. The result of this research showed that the difference in addition of aloe vera gel to skin lotion significantly affected to specific gravity, moisture activities of product, pH and antioxidant activity and did not significantly affected to viscosity and emulsion stability. The best products based on organoleptic test on skin lotion was treatment B (addition of aloe vera gel 5 g), with an average of panelists score to appearance 87 %, color 83 %, aroma 70 %, thick consistency 77 % and stickiness 87 %, while the result physical and chemical analysis skin lotion of treatment B (addition of aloe vera gel 5 g) is viscosity 8.333 cP; specific gravity 1.01; emulsion stability 100 %; product moisture 98.07 %; pH value 7.771; antioxidant activity 16.60 %; irritation value 0; and total plate count 9.5 x 101 cfu/ml.

The treatment of this research is the addition of dragon fruit skin extract of 5%; 10%; 15%; 20%; and 25%. Observations on the resulting bio-plastic product are physical properties and mechanical properties. Physical properties test include thickness, density, water absorption and mechanical properties test including tensile strength test, percent elongation. The results showed that the difference of dragon fruit color extract concentration in bioplastic has effect on thickness, density, water absorption, tensile strength, elongation percentage. The best treatment based on bio-plastic mechanical properties is on E treatment (addition of 20% dragon fruit skin extract).

This research used a completely randomized design (CRD) consisting of 5 treatments and 3 replications. Data were analyzed statistically using ANOVA followed by Duncan test's New Multiple Range Test (DNMRT) at 5% level. Treatment in the present research is the addition of aloe vera gel at 0%; 6%; 7%; 8%; and 9%. Observations on the resulting liquid soap products were organoleptic, physical properties, chemical properties of soap, antimicrobial test, moisturize activities test, and irritation test. The physical propertiestest to soaps include viscosity, specific gravity and total foam. For chemical propertiestest to soaps include pH andfree alkali. The results showed that the difference in concentration of aloe vera gel to liquid soap significantly affected to viscosity, pH, antimicrobial and moisture acti...

Research paper thumbnail of Analisis Pendapatan Usahatani Sayuran Hidroponik Dengan Sistem Deep Flow Technique (DFT)

Jurnal Teknik Pertanian Lampung (Journal of Agricultural Engineering), 2020

Namun, budidaya sayuran hidroponik membutuhkan ketelitian, keterampilan khusus dan biaya produksi yang relatif tinggi. Penelitian ini bertujuan untuk menganalisis keuntungan budidaya sayuran hidroponik berdasarkan sistem budidaya hidroponik yang digunakan dan jenis sayuran yang dibudidayakan. Tiga unit instalasi hidroponik DFT dengan ukuran 2 m x 1 m x 2 m digunakan untuk membudidayakan sayuran pakcoy, caisim dan kangkung. Berdasarkan analisis efisiensi usahatani, maka budidaya sayuran hidroponik dengan sistem DFT layak diusahakan dengan rasio (B/C) untuk budidaya pakcoy sebesar 1,5, rasio (B/C) untuk budidaya caisim sebesar 1,1 dan rasio (B/C) untuk budidaya kangkung sebesar 1,4.

Research paper thumbnail of Karakterisasi Plastik Biodegradable Dari Pati Limbah Kulit Pisang Muli Dengan Plasticizer Sorbitol

Penelitian ini bertujuan untuk mengetahui pengaruh pati kulit pisang muli terhadap karakteristik ... more Penelitian ini bertujuan untuk mengetahui pengaruh pati kulit pisang muli terhadap karakteristik film plastik biodegrdable dan untuk mengetahui konsentrasi pati kulit pisang muli terbaik. Perlakuan pada penelitian ini adalah penambahan pati kulit pisang muli 1 g, 1.5 g, 2 g, 2.5 g dan 3 g. Pengamatan pada produk plastik biodegradable yang dihasilkan adalah sifat fisik, sifat mekanik dan degradasi. Uji sifat fisik meliputi uji ketebalan, densitas, penyerapan air dan sifat mekanis termasuk uji kuat tarik, persen perpanjangan dan degradasi. Hasil penelitian menunjukkan bahwa perbedaan konsentrasi ekstrak perpanjangan berpengaruh terhadap ketebalan, kepadatan, daya serap air, kekuatan tarik, persentase perpanjangan dan degradasi. Perlakuan terbaik berdasarkan sifat mekanik plastik biodegradable adalah penambahan 1 g pati kulit pisang muli. Kata kunci-plastik biodegradable; pati; pisang muli
