    Penelitian ini bertujuan untuk mengetahui pengaruh indikator warna dari ekstrak daun dan buah tanaman pucuk merah (Syzygium oleana) terhadap karakteristik plastik biodegradable dan untuk mengetahui apakah indikator warna dari ekstrak daun dan buah tanaman pucuk merah (Syzygium oleana) dapat digunakan sebagai indikator warna smart packaging. Penambahan ekstrak daun dan buah pucuk merah berpengaruh terhadap karakteristik kadar air, ketebalan, densitas, daya serap air, aktivitas antioksidan, total polifenol dan kadar antosianin plastik biodegradable. Plastik biodegradable dengan indikator warna ekstrak daun dan buah tanaman pucuk merah dapat digunakan sebagai smart packaging karena dapat mendeteksi kerusakan fillet ikan ditandai dengan berubahnya warna indikator selama penyimpanan seiring dengan rusaknya fillet ikan. Dengan nilai perubahan warna (ΔE/TCD) yaitu untuk smart packaging indikator warna daun pucuk merah yaitu pada hari pertama ke-1 sampai hari ke-5 dari 0,00 menjadi 2,63 artinya perubahan warna tidak dapat dideteksi dengan mudah dengan mata biasa, sedangkan nilai (ΔE/TCD) perubahan warna indikator smart packaging dari ekstrak warna buah pucuk merah yaitu meningkat dari hari ke-1 sampai hari ke-3 dari 0,00 menjadi 10,96 dan pada hari ke-4 turun menjadi 5,48 dan pada hari ke-5 meningkat lagi menjadi 6,77 artinya perubahan warna dapat dideteksi dengan mudah dengan mata biasa.

    This research was aimed to determine the effect of addition of aloe vera gel toward characteristic of skin lotion and to determine the best addition of aloe vera gel. This research used a completely randomized design (CRD) consisiting 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

    This research was aimed to determine the effect of aloe vera gel to liquid soap moisturize activities of liquid soapto skin, and to determine the best addition of aloe vera gel. 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 activities of product and did not significantly affected to specific gravity, free alkali, and total foam. The best products based on organoleptic test on liquid soap was treatment B (addition of aloe vera gel 6%)

    Bioplastic is one solution to the large amount of plastic waste that is a problem for the environment because it is difficult to degrade. This study aims to characterize the bioplastic film of ambon banana peel starch and to determine the best ambon peel starch concentration. Observations on the resulting bioplastic products are physical properties and mechanical properties. Physical properties tests include thickness, density, water absorption and mechanical properties including tensile strength, percent elongation, young's modulus. The results showed that differences in starch concentration affected the thickness, density, water absorption, tensile strength, elongation and young's modulus. The best treatment based on the mechanical properties of bioplastics was the addition of 1 g of Ambon banana peel starch
