Abstract

This research aimed to find out the diversity, evenness, and distribution abundance of epiphytic ferns scattered in the area around Villa Silma, Cilember District, Bogor Regency. This research used a purposive sampling method by taking samples as the data determined by determining the characteristics of the epiphytic ferns found. Collecting data in this research exploratively by exploring all epiphytic ferns found in the area and observations on the morphology of epiphytic ferns. Data were analyzed through the diversity index using the Shannon-Wiener index, distribution of abundance using the Margalef index, and evenness index using based on the value of the Shannon-Wiener species diversity index. The research results obtained that three species of epiphytic ferns were found in the area around Villa Silma, namely Asplenium nidus L., Asplenium adiantum-nigrum L., and Pyrrosia piloselloides (L.) M.G. Price with different numbers of individuals. The diversity index of epiphytic fern is 0.7 which indicates the level of diversity in the area is low. Then, The distribution of abundance and evenness epiphytic ferns is 0.6 which indicates that there are epiphytic ferns dominant in the area and the number of individuals in each species is unevenly distributed. The most abundant fern epiphytic was found is Asplenium nidus L. with 84 individuals. This because the environment allows it to spread and grow the spores of this epiphytic fern plant properly.

Abstract

Minyak jelantah merupakan minyak goreng yang telah digunakan berulang kali. Untuk menghilangkan bau dan kotoran dari minyak, karbon aktif digunakan untuk pemurnian. Penelitian ini bertujuan untuk berkolaborasi dengan masyarakat untuk menghasilkan produk sabun cuci tangan dari minyak jelantah serta menguji pH, kadar air, dan kestabilan busa sabun. Penelitian dilaksanakan di Pos RW 09 Rawamangun dan Laboratorium FMIPA UNJ pada bulan Agustus sampai November 2022 dengan menggunakan metode eksperimen kuantitatif. Hasil penelitian menunjukkan bahwa untuk uji pH kedua kelompok mempunyai nilai pH 9, untuk uji kadar air kelompok 1 mempunyai nilai 6,2% dan kelompok 2 mempunyai nilai 5,6%, dan untuk uji stabilitas busa kelompok 1 mempunyai nilai sebesar 96,24% dengan standar eror 0,360 dan kelompok 2 memiliki nilai sebesar 94,65% dengan standar eror 1,104. Berdasarkan hasil, sabun cuci tangan dari minyak jelantah telah memenuhi persyaratan standar nasional sabun batangan.

Abstract

Repeated use of cooking oil produces waste in the form of waste cooking oil. Apart from being dangerous for health, waste cooking oil is also dangerous for the environment. To overcome this, waste cooking oil might be used for other harmless side products such as soap. To meet the soap standard, the waste oil must be reprocessed. Training on making soap from waste cooking oil has never been carried out before in the Pekan Nenas Pontian, Johor Bahru, Malaysia, so this service activity focuses on introducing, training, and implementing bar soap making from waste cooking oil to the community in the Pekan Nenas Pontian, Johor Bahru, Malaysia, as an effort to reduce waste cooking oil. The counseling webinar was held boldly on June 24, 2023. Meanwhile, soap-making training was held at Pekan Nenas Pontian on August 5, 2023. Soap quality testing was conducted at the Biochemistry Laboratory, State University of Jakarta, in September 2023. This activity used the active participation strategy method. The data obtained is in the form of social data, namely pre-test and post-test results, and scientific data in the form of soap quality tests, which are compared with the Indonesian National Standard (SNI) for solid soap, including pH tests, water content tests, foam height, and stability tests. Community knowledge has increased, as shown by the post-test score having an average of more than 60, namely 75, and the highest score is 90. This community service activity was a success.
