Customer satisfaction is perceived as business strategy’s key component and critical differentiation in a competitive marketplace. The recorded huge transactions per day in marketplaces can be used as useful information to evaluate customer satisfaction. A sophisticated method, such as data mining, is necessary to analyze this massive, multifaceted, and versatile empirical data generating accurate predictions. This research purported to investigate marketplace customer satisfaction as a reference to determine service and quality improvements. In conclusion this study draws two conclusive results: (1) The majority of marketplace consumers preferred the lead-time sensitive over price-sensitive; and (2) The Neural Net empirically showed as the most appropriate robust data mining technique among other techniques to predict marketplace customer satisfaction indicating by fittest accuracy, F score and ROC curve
Kampung Totokaton merupakan salah satu dari 9 Kampung yang berada di wilayah kecamatan Punggur, kabupaten Lampung Tengah, Provinsi Lampung yang termasuk dalam wilayah menengah kebawah yang sulit mendapatkan akses bahan bakar LPG. Kampung Totokaton mempunyai potensi biomassa yaitu limbah kotoran ternak sapi yang cukup banyak yang dapat dimanfaatkan sebagai sumber energi bahan bakar biogas. Limbah kotoran sapi tersebut selama ini belum dapat termanfaatkan dengan maksimal. Oleh karena itu, tim pengabdian masyarakat ITERA melakukan pembangunan instalasi teknologi reaktor biogas berukuran 4 m3 yang digunakan untuk mengkonversi kotoran sapi menjadi sumber energi terbarukan pengganti LPG yang lebih ekonomis dan ramah lingkungan. Adapun pelaksanaan pengabdian yang dilakukan adalah observasi/survei lokasi, kerjasama dengan mitra, pembangunan instalasi biogas, monitoring/evaluasi, dan pelaporan. Hasil dari program pengabdian masyarakat ini adalah reaktor biogas dengan warna nyala api yang dihasilkan berwarna biru yang menandakan kualitas biogas yang dihasilkan secara visual tidak berbeda dengan gas LPG yang selama ini digunakan. Kandang sapi juga terlihat menjadi lebih bersih. Hal ini berarti dengan adanya penerapan teknologi tepat guna biogas sangat membantu warga dan selangkah lebih maju dalam hal kemandirian energi. Hasil analisis survei kepuasaan masyarakat menunjukkan hampir 95% yang menyatakan sangat puas dan merasa sangat terbantu dengan kehadiran Tim pengabdian masyarakat ITERA.
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.
Indonesia has seen a rise in Black Soldier Fly maggots. Maggot farming offers great economic diversification. BSF (maggot) larvae may eat many organic materials, making them special. This helps bioconvert organic waste, which can damage the environment and harm people's health if not treated properly. Protein-rich maggots are animal feed ingredients. Serious maggot cultivation can create new jobs. This maggot culture has a hidden gem that must be removed. Maggot oil studies still produce animal feed. Maggot oil is antibacterial and emollient, making it a cosmetic and medicinal ingredient, according to worldwide studies. Cosmetics use fats as viscosity enhancers or emulsifiers. As a proof of concept, BSF larvae fat will be used in hand cream compositions to show its potential in organic waste processing, animal feed, and health and beauty additives. Naturally, national and international scientific journals and social media have not broadly shared this information and talents. The Cosmetic Engineering study program's Community Service Team shares information, insights, and talents to connect research, education, and community applications. The ITERA Cosmetics Engineering team will train maggot breeders in Triharjo village to increase maggot production and diversify maggot products to boost sales.
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.
