The purpose of this study were to analyze the quantity of microorganisms in some local ragi tape and determine the panelists' acceptance of the "tape jusinta" was produced. This type of research is an experiment with a solid substrate fermentation method. The used ragi tape is 4 kinds of local ragi tape from South Sulawesi Province (ragi tape A, B, C, and D) and 1 type of local ragi tape from Southeast Sulawesi Province (ragi tape E). The Tape Jusinta was produced by fermentation of a solid mixture of purple sweet potato and cassava tubers in a ratio of 1: 1 using 5 kinds of local ragi tape. Analysis of microbial quantity in ragi tape includes the number of molds, yeasts and bacteria in viable count using the Standard Plate Count (SPC) method. Panelist acceptance of the Tape Jusinta product was analyzed using the Hedonic test with a numerical scale range of "6". Data were analyzed descriptively and inferentially using Anova and Duncan's Multiple Test. The results of the data analysis showed that the level of palatability of the panelists to the tapejusinta fermentedragi tape B was not different from the tape jusinta fermented ragi tape A and C, but the tape jusinta fermented by Cragi tape was different from the results of fermentation ragi tape D and E. The “tape jusinta” fermented ragi tape B is preferred over the tape jusinta fermented ragi tape A, C, D and E with the highest average panelist rating of 4.15. The quantity of microorganisms on ragi tape B are mold types as much as 1.0 x 104 cfu / g, yeast 8.0 x 103 cfu / g and bacteria 5.7 x 104 cfu/ g. Keywords: cassava roots, purple sweet potatoes, ragi tape, "tape jusinta", palatabilityAbstrakTujuan penelitian adalah menganalisis kuantitas mikroorganisme pada beberapa ragi tape lokal dan mengetahui daya terima panelis terhadap “tape jusinta” yang dihasilkan.

Ragi tape yang digunakan adalah 4 macam ragi tape lokal yang berasal dari Provinsi Sulawesi Selatan (ragi tape A, B, C, dan D) dan 1 macam berasal dari Provinsi Sulawesi Tenggara (ragi tape E). Tape Jusinta dihasilkan melalui fermentasi substrat padat campuran ubi jalar ungu dan umbi ubi kayu dengan perbandingan 1 : 1 menggunakan 5 macam ragi tape lokal. Analisis kuantitas mikroba pada ragi tape meliputi jumlah kapang, khamir dan bakteri secara viable countmenggunakan metode Standard Plate Count (SPC). Daya terima panelis terhadap produk Tape Jusinta dianalisis menggunakan uji Hedonik dengan rentang skala numerik “6”.Data dianalisis secara deskriptif dan inferensial dengan Anava dan Duncan’s Multiple Test. Hasil analisis data menunjukkan bahwa tingkat kesukaan (palatability) panelis terhadap tape jusinta hasil fermentasi ragi tape B tidak berbeda dengan tape jusinta hasil fermentasi ragi tape A dan C, namun tape jusinta hasil fermentasi ragi tape C berbeda dengan hasil fermentasi ragi tape D dan E. Tape jusinta hasil fermentasi ragi tape B lebih disukai daripada tape jusinta hasil fermentasi ragi tape A, C, D dan E dengan rata-rata penilaian panelis tertinggi yaitu 4.15.

The target partners in the Public Partnership Program (PKM) of Jusinta Tape Fermentation technology are students at the XII grade SMA Yatama Mandiri Islamic Boarding School, Gowa Regency. The location of the Islamic boarding school is in the area of Pallangga Subdistrict, Gowa Regency, which has the first highest cassava production and second highest sweet potatoes production land in South Sulawesi.. The implementation of activities is supported by the field of expertise of the implementing team related to the results of research in the form of a tape product called "Tape Jusinta" (Muhiddin, et al., 2018). This tape is made through the fermentation process of a mixture of purple sweet potato tubers and cassava roots using a local ragi tape starter. The process of making tape from purple sweet potato (Ipomoea batatas L.) and cassava roots (Manihot esculenta Crantz) with a local ragi tape starter, has received patent certificate in January 2020. Another thing that supports the potential of students who really need knowledge development and skills to grow economically productive businesses with Islamic boarding schools located in sweet potato and cassava production centers. The output target that is expected to be achieved in this PKM activity is that students have the knowledge and skills in producing Jusinta Tape through fermentation technology. The results of the activity are expected to be developed into a learning tool for biotechnology materials. The methods used are: lectures, demonstrations, discussions, practice and mentoring. The instruments used to determine the participants' responses to the Tape Jusinta fermentation technology training were questionnaires, observation, interviews, and documentation. The results achieved were that the participants could easily understand the processing of purple sweet potato and cassava roots into Tape Jusinta through fermentation technology. As many as 60% of the participants from the teacher group answered that the Tape Jusinta fermentation technology was in accordance with the students' abilities and was suitable to be applied in biotechnology learning. The organoleptic test results show that the Tape Jusinta product has a light purple color with an average of 4.4, the aroma of alcohol is less sharp with an average of 4.2, a soft texture with an average of 8.6, a slightly sour taste with an average of 4.4, the taste is quite sweet on average 6.5, and product palatability by the society is well received with an average of 8.9.

The partner of this Community Partnership Program (PKM) was a the MGMP IPA of Bantaeng Regency. The problem with this dedication is that there are still many science teachers who have not mastered Nata de Coco biotechnology. While they as educators in junior high schools must master several applications of biotechnology to manage practicum in Biotechnology learning materials according to the curriculum. Biotechnology training is very appropriate for Science Teachers, so that their insights and skills in practicum management especially on biotechnology materials can be sufficient as an effort to increase the competence of professional teaching staff. The expected output target in this PKM activity is that science teachers have the knowledge and skills in Nata de Coco biotechnology. The results of this activity can be developed into one of the learning tools on Biotechnology material in junior high schools. The method used is: lecture, demonstration, discussion, practice and assistance.
