Abstract

The purpose of this study were to determine which part of tamarind (asam) that had highest antioxidant activity and which formula of kunyit asam baverages had highest antioxidant activity and preferred by consumers. The experiment was conducted in two stages namely: part of tamarind and formula of kunyit asam baverages. The results showed that tamarind leaves with cooking time 2.5 minutes had the highest antioxidant activity with total phenol 0.75 g GAE/100g tamarind leaves extract; antioxidant capacity 0.053% evaluated by DPHH method and vitamin C: 0.252 mg/100 g. The kunyit asam baverages which the highest antioxidant activity and preferred by consumers, produced from formula: 5 part of turmeric, 25 part of tamarind leaves, 70 part of water, with total phenol: 1.06 g GAE/100g formula baverages, antioxidant capacity: 0.123% and vitamin C: 0.688 mg/100 g.ABSTRAKTujuan penelitian ini adalah untuk menentukan bagian asam yang menghasilkan aktivitas antioksidan tertinggi dan formulasi minuman kunyit asam yang memiliki aktivitas antioksidan tertinggi dan disukai panelis.

Abstract

Tujuan penelitian adalah  mengidentifikasi profil permukaan dan gugus fungsi bioplastik yang terbuat dari pati singkong termodifikasi. Penelitian dilaksanakan dengan metode eksplorasi, yang diawali dari pembuatan bioplastik pati singkong termodifikasi dan dilanjutkan dengan mengamati profil permukaan bioplastik pati singkong termodifikasi pada sisi melintang dan membujur dengan menggunakan Scan Electron Microscope (SEM), serta mengidentifikasi gugus fungsi pada polimer yang terbentuk dalam bioplastik menggunakan spectrometer FTIR. Hasil peneltian menunjukkan bahwa profil permukaan bioplastik pada tampak membujur menunjukkan adanya jaringan-jaringan gel yang dibentuk oleh bahan polimer pati termodifikasi dengan rongga-rongga udara. Profil bioplastik pati singkong (tapioka) tampak samping atau melintang menampilkan susunan berlapis ke arah vertikal dengan ketebalan 379 mikron, sementara itu perbesaran 2500 kali tampak melintang menunjukkan jaringan-jaringan gel yang dibentuk oleh bahan polimer pati yang tersusun berbentuk gelombang atau ombak ke arah vertikal. Bioplastik yang dibentuk dari polimer pati termodifikasi mengandung gugus fungsi hidroksil (O-H) yang berikatan dengan hydrogen, alkana (C-H), aldehida (C-H), ikatan hidrogen asam karboksilat, alkuna (C=C), ester, senyawa aromatik sederhana, karboksil (C-O), alkena (C=C) serta hidrokarbon -(CH2)n.

Abstract

This study aims to analyze the problematic problems in regional development and determine effective alternative strategies in developing eco-edu-spiritual-tourism-based tourism. The method used is the SLA (Sustainable Livelihoods Approach) approach based on three stages of activities, namely (1) the awareness, participating, institutionalization stages along with the SWOT analysis. The results showed an alternative strategy used to model the potential for the development of urban eco-edu-spiritual-tourism as an effort to support the creative economy in the ayung tributary of Denpasar City is the SO (Strengths-Opportunity) Strategy, which is a strategy that uses power to take advantage of opportunities namely (1) Optimizing the effective use of tourist land; (2) Development of centers of economic activity and improvement of the quality of tourism products; (3) Development of eco-edu-spiritual tourism-based tourism packages as an effort to develop sustainable urban tourism. It can be suggested in research that the Government through the relevant Dinas is expected to facilitate tourism support infrastructure and involve official activities as an effort to promote Tukad Bindu as an area that has succeeded in revitalizing the clean river in urban areas so that economic improvement can be achieved significantly.

Abstract

This study aimed to know cream of turmeric tamarind leaves on the treatment of concentration emulsifier and stirring time and to determine the concentration emulsifier and stirring time to produce characteristics of cream fulfill requirement of SNI. This study used a randomized block design with two factors. The first factor was the concentration emulsifier which consist of three levels, namely 3, 5 and 7%. The second factor is stirring time which consist of three levels, namely 5, 7.5 and 10 minutes. The data were analyzed by analysis of variance (ANOVA) and continued with the tukey test. The result of the study showed that concentration emulsifier has an effect on the adhesion time, pH, viscocity and spread power. The stirring time has an effect on the adhesion time. Concentration emulsifier 5% and 7% with stirring time 10 minutes were creams that fulfill requirement of SNI. The characteristics cream of concentration emulsifier 5% with stirring time 10 minutes is: homogeneus, separation ratio = 1, adhetion time 48.52 seconds, viscocity 3550 cp, spread power 6.72 cm and pH 6.60. The characteristics cream of concentration emulsifier 7% with stirring time 10 minutes is: homogeneus, separation ratio = 1, adhetion time 28.82 seconds, viscocity 3650 cp, spread power 6.79 cm and pH 6.45.

Abstract

This study aimed to determine the effect of value Hydrophile-Liphophile Balance (HLB) and type of extract on the characteristics of turmeric-aloe vera cream (Curcuma domestica Val. – Aloe Vera) also determine the HLB and the right type of extract to produce the best characteristics of turmeric-aloe vera cream (Curcuma domestica Val. – Aloe Vera). This study used a factorial randomized block design with two factor. The first factor was the HLB which consist of three levels, namely HLB 9, 10 and 11. The second factor was an extract consisting of two levels, namely the addition of turmeric and aloe vera extract. The result of the study showed that HLB has an effect on the spread power. The extract has an effect on the degree of acidity and total phenol. The treatment of HLB and the addition of the extract did not affect homogeneity, separation ratio, viscocity and adhesion time. All creams fulfill the characteristics of SNI. Aloe vera and turmeric extract cream with HLB 10 were the best formulated cream at the 6th week storage of the following characteristics: homogeneus, separation ratio =1, spread power 4.8-5.2 cm, viscocity 15733–16667 cp, adhesion time 14.43–17.31 second, pH 4.87-5.00 and total phenol 1.08–1.36 mg GAE/g.

Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh penambahan bubuk kakao dan suhu pemanasan terhadap karakteristik produk krim bodi scrub, serta menentukan persentase penambahan bubuk kakao dan suhu pemanasan yang terbaik untuk menghasilkan produk krim bodi scrub. Penelitian ini menggunakan Rancangan Acak Kelompok Faktorial (RAKF) dua faktor dengan faktor pertama ialah persentase penambahan bubuk kakao dan faktor kedua ialah suhu pemanasan. Persentase penambahan bubuk kakao terdiri dari 5 taraf yaitu P0 (0%), P1 (3%), P2 (6%), P3 (9%), P4 (12%) serta variasi suhu pemanasan terdiri dari 2 taraf yaitu T1 (65oC) dan T2 (75oC). Dari sepuluh kombinasi perlakuan dikelompokkan menjadi 2, sehingga diperoleh 20 unit percobaan. Data dianalisis menggunakan One Way Anova. Apabila terdapat pengaruh perlakuan terhadap parameter yang diamati, dilanjutkan dengan uji Duncan. Hasil penelitian menunjukkan perlakuan yang menghasilkan krim bodi scrub terbaik ialah penambahan bubuk kakao 9% dan suhu pemanasan 65oC dengan karakteristik: viskositas 19.625 cp, diameter daya sebar 5,00 cm, rasio pemisahan krim F=1, pH 6,52, dan kandungan senyawa fenolik 15,21 mg GAE/g
