Abstract

Sabun cair cuci piring dapat digunakan untuk membersihkan berbagai peralatan di rumah mulai dari piring dan noda minyak yang membandel. Bahan utama dalam pembuatan sabun cair cuci piring adalah surfaktan. Selain itu, senyawa gliserin juga digunakan sebagai pelembut dalam sediaan sabun cair cuci piring. Gliserin memiliki harga yang cukup mahal. Pada penelitian ini menggunakan ekstrak air tanaman lidah buaya (Aloe vera L.) sebagai pengganti gliserin dalam pembuatan sabun cair cuci piring. Tujuan penelitian ini yaitu pembuatan sabun cair cuci piring menggunakan ekstrak air tanaman lidah buaya. Ekstrak air tanaman lidah buaya berfungsi sebagai humektan (pelembut) alami dalam sediaan sabun cair cuci piring. Prekursor yang digunakan adalah sodium lauryl sulfate (SLS), sodium sulfate (Na2SO4), dan ekstrak tanaman Aloe vera L. Metode yang digunakan melalui pendekatan in-situ yaitu dengan mencampurkan prekursor dengan ekstrak air tanaman lidah buaya secara langsung. Hasil uji fitokimia fraksi air ekstrak Aloe vera L. menunjukkan adanya senyawa metabolit sekunder seperti flavonoid, alkaloid, tanin, dan saponin. Dalam formulasi ini, saponin berperan sebagai penstabil ketinggian busa dan sebagai humektan. Sabun cair cuci piring berwarna hijau transparan dengan nilai pH 8,7, stabilitas tinggi busa 37% selama 25 hari, nilai viskositas 1940 mPa.s, dan densitas 1,082 g/mL. Selain itu, kadar alkali bebas dan kadar air masing-masing 0,02% dan 41,2%, dengan homogenitas partikel yang baik. Pada hasil penelitian ini dapat disimpulkan bahwa ekstrak Aloe vera L. berpotensi sebagai sumber humektan alami dalam formulasi sabun cair cuci piring.

Abstract

This article aimed to do research on the economic empowerment of rural women using Participatory Action Research approach. PAR required performing research to define a problem or implement information as solutions to problems that have been defined. PAR is "research by, with, and for people" as opposed to "research on person." Participatory action research is participatory in the sense that it is a necessary condition that people play a key role and have relevant information about the existing social system (community) under review, and that they participate in the design and implementation of the action plan based on the findings of the research. This research was preceded in the search for problems faced by women in Jatisari Village, Lampung Province. The solutions obtained were in the form of providing knowledge, entrepreneurial skills, and examples of how to produce innovative products by utilizing the natural resources around them. Empowerment activities include three stages, namely: (1) Providing counseling about the possible benefits of natural resources in the environment as products for women’s needs by providing examples of the use of plants that are easy to obtain and grow, for example aloe vera which is easily found in the yard to produce a product; (2) Provide counseling on how to become a woman entrepreneur and analyze household products with high demand for daily needs (eg liquid dish soap); and (3) Demonstrating how to use aloe vera as a component in the manufacture of liquid dish soap.

Abstract

The microwave hydriffusion gravity (MHG) method is a relatively new extraction method in order to improve the quality of oil obtained from plant materials or spices. The extraction process is carried out without involving solvents so it is safe for consumption. However, the MHG method has never been applied to the extraction of candlenut (Aleurites moluccana L) seeds. The operating conditions and variables in the research on the extraction process of Aleurites moluccana L are microwave power (300; 450; 600 W), extraction time (15-75 minutes) with 15-minute intervals, material size (1;2;3 cm), mass of raw material 100 gr, and atmospheric pressure. Material treatment consisted of 3 types of material conditions including seed material which had been roasted for 10 minutes over low heat, seed material which had been in the oven for 45 minutes, and seed material which had been without pretreatment. The results of the oil extract were analyzed using GC-MS to identify the components of the constituent compounds. Then, evaluating the mathematical modeling of the extraction process is based on first and second order kinetics. Roasted material showed the highest yield with material size parameter in 1 cm, microwave power of 600 W, and extraction time at 30 minutes, produced 5.55% (%w/w). Furthermore, the pyrazine component (36.814%) is the largest compound from the extraction of Aleurites moluccana. The first-order kinetic model has a regression that is close to the experiment with (R2 = 0.9453). Modeling quality is also supported by a very small total sum of squares (SST) value of 6,44E10-4. Therefore, the MHG method is quite effective in producing Aleurites moluccana oil with better quantity and quality
