Abstract

Research on improving student learning outcomes using concept mapping  strategy  on  hydrocarbon  material  in  class  X-1  SMAN  10 Banjarmasin has been implemented. This  research  aims  to (1) know  teacher’s and students’ activities, (2) improve learning outcomes (3) study students response to concept mapping strategy on hydrocarbon material. This research used classroom action research design, with 2 cycles. Subjects of this research were students of class X-1 in SMAN 10 Banjarmasin. Data were obtained from assessment of teacher activity, student activity, cognitive tests and questionnaire  responses. The results showed that the use of map concept strategy increased: (1) teacher activities, from good criteria in the first cycle to very good criteria in the second cycle, (2) students’ activities from good criteria in the first cycle to  very good criteria  in  the  second  cycle,  (3) students outcomes increased from   63.28% in the first cycle to 81.21% in the second cycle; (4) Learning using  map concept received a positive response from the students.

Abstract

Abstract. Utilization of chitin as a stationary phase of TLC to separate the compound components from plants had been carried out. The objective of this study was to investigate (1) the effectiveness of chitin as a stationary phase in TLC to separate the compound components of plants, and (2) composition of compounds in plant extracts that can be separated by chitin. Research method is experiment in laboratory. Sampling technique of plant extract (mahogany seed, turmeric rhizome, and pandanus leaf) using random sampling technique, while shrimp shrimp skin is shrimp waste from Indu Manis Banjarmasin factory. Data were analyzed descriptively qualitative. The results showed that chitin rendemen successfully isolated from shrimp skin was 36,44%. Chitin is effectively used as an alternative to stationary phase in TLC to separate the compound components from plant sample extracts (mahogany seeds, pandanus leaves, and turmeric rhizomes). Keywords: chitin, stationary phase of TLC, and separation of plant compound components. Abstrak. Telah dilakukan penelitian tentang pemanfaatan kitin sebagai fasa diam KLT untuk memisahkan komponen senyawa dari tumbuhan. Penelitian ini bertujuan untuk mengetahui (1) efektivitas kitin sebagai fasa diam pada KLT untuk memisahkan komponen senyawa dari tumbuhan, dan (2) komposisi senyawa dalam ekstrak tumbuhan yang mampu dipisahkan oleh kitin. Metode penelitian adalah eksperimen di laboratorium. Teknik pengambilan sampel ekstrak tumbuhan (biji mahoni, rimpang kunyit, dan daun pandan) menggunakan teknik random sampling, sedangkan kulit udang merupakan limbah kulit udang dari pabrik Indu Manis Banjarmasin. Data dianalisis secara deskriptif kualitatif. Hasil penelitian menunjukkan bahwa rendaman kitin yang berhasil diisolasi dari kulit udang sebesar 36,44%. Kitin cukup efektif digunakan sebagai alternatif fasa diam  pada KLT untuk memisahkan komponen senyawa dari ekstrak sampel tumbuhan (biji Mahoni, daun Pandan, dan rimpang Kunyit).  Kata Kunci: kitin, fase diam KLT, dan pemisahan komponen senyawa tumbuhan.

Abstract

Avocado (Persea americana) contains a lot of vitamin A, vitamin B, vitamin C and vitamin E which is good to be used in skin care. One of the cosmetics for skincare is lotion, which is a liquid emulsion consisting of oil phase and water phase stabilized by emulgator. Lotion is used to protect and maintain skin moisture level. The purpose of this research was to formulate and evaluate the lotion in order to assure the physical characteristic and stability were accepted according to the Handbook of Pharmaceutical Excipients and Indonesia Pharmacopeia requirements.Formulation were made by using these following ingredients: glyceryl monostearate, cera alba, tween 80, glycerin, liquid paraffin, benzyl alcohol, perfume, aquadest. The study used 2 variation of concentration, which is  0.5% and 1% avocado extract as active substance, besides there is variations in glyceryl monostearate (5.5% and 5.7%), cera alba (2.7% and 2.9%), tween 80 (3.5% and 3.7%), glycerin (10% and 12%), liquid paraffin (10% and 12%), and benzyl alcohol (0.15% and 0.17%) in formulations I and II. Lotion was then tested for its physical properties, which include organoleptic test, homogeneity test, pH test, and spreadability test, lastly hedonic and irritation test were also being examined.Based on the results of physical properties test, both lotion formulations showed a viscous texture, beige and dark beige color with a distinctive odor, homogeneous, not irritating, have a pH value in the range of 4.55-5.31 with 4.9-5.15 cm spread. In the hedonic test on 10 panelists, lotion I formulation gave the most satisfaction score and comforty from respondents. Respondent's satisfaction on the appearance comprise the texture, color, and odor. Besides, viscosity and spreadability were also marked as how comfort the lotion is when it was applied to the respondent’s skin.Keywords :  Avocado, Extract, Lotion, Cosmetic, Moisturizer

Abstract

The large consumption of papaya in Indonesia causes the availability of papaya seeds to be abundant and has not been used wisely. Papaya seeds contain secondary metabolites such as phenols, terpenoids, alkaloids and saponins which have an antibacterial activity. The purpose of this study was to develop papaya seeds into a cosmetic form and in this study is to formulate it into solid soap. The research was initiated by making an extract which was then formulated into solid soap with various concentrations of 2%, 4%, and 6%. Soap is tested for its characteristics to meet the requirements of soap in SNI 06-3532-1994. The soap meets the criteria for the pH requirement, which is between 9-10, has a water content of 1%, free alkali content of 0.044%, forms a stable foam and does not change during storage by using cycling test method.
