<![CDATA[Banana (Musa sp.) is the most widely consumed fruits since the children age up to the elderly. This is because bananas have quite complete nutrient content such as carbohydrates, proteins, vitamins and minerals, making it beneficial for the human body. People normally only consume and discard any banana skin. Therefore; it needs solutions to deal with the banana peel waste. Banana peels contain high enough nutrients that are carbohydrate 18.5%, phosphorus 28 mg, water 72 g, and some other chemical substances. The high nutrient content on the banana peel is potential to be used as food, one of which is in the form of nata. Nata is a product of microbial fermentation using Acetobacter xylinum. Nata can be made from coconut water waste, liquid waste or waste bark out pineapple and banana peel waste (Nata de Banana Skin). This study aimed to determine the effect of various types of banana peels using A. xylinum on the quality of nata de banana skin. The results showed that different types of banana peel affect the quality of Nata de Banana Skin, both on its flavor and its yield of Nata de Banana Skin. The pisang raja skins give the most optimal results for nata thickness and also perform the best organoleptic values.]]>

<![CDATA[Argumentation skill is a part of the critical thinking ability needed by students to be successful in learning science. This study aims to understand the effect of the implementation of 4 Step Jigsaw (4SJ) and original jigsaw learning models in rehearsing the argumentation skill of junior high school students in the concept of plant structure and function. This argumentation skill is further investigated in the lens of varied students’ level of confidence. This study employs the quasi-experiment factorial 2 x 2 with the type of Pretest Posttest Nonequivalent Control Group design. The population was the students from grade 8 SMPN 17 Batanghari with total of 106 students, consisted of 44 males and 62 females. Some 53 students were recruited to be the sample grouped into 2 classes, i.e., the class 8A as the class 4SJ and the class 8C as the original jigsaw class. Data were collected using a valid self-confidence questionnaire and a valid pretest and a posttest in argumentation. Data were analyzed using two-way Anova test and statistics descriptive techniques. The results show that the 4SJ students have higher average of argumentation skill score (77.77) than the jigsaw students (71.17). It was also factual that students with better self-confidence also have higher average of argumentation skill score (75.13) than  those with lower self-confidence (73.81). The results of two-way Anova test emphasize that there is an effect of the utilization of the models on the students’ argumentation skill. There is also an effect of the students’ self-confidence on the students’ argumentation skill. Even though it was very weak, it can be said that there is a potential for the learning models and the self-confidence to have an interaction in causing the growth of the students’ argumentation skill. It can be concluded that appropriate learning models and suitable self-confidence may affect students’ learning outcomes.]]>

<![CDATA[Petunia hybrid Vilm. is an ornamental plant that has the potential to be developed because its flowering period does not know the season and comes with various motifs and flower colors that can add cultivation and commercial value. Information on the morphological characteristics of flowers and flowering phenology is the basis for their development. The aim of this study was to characterize the morphological structure of flowers and observe a series of phases in flower development stages associated with environmental factors. This research was conducted in the sustainable twin housing complex in the city of Jambi on March 25–May 27, 2022, and the data obtained was analyzed descriptively, qualitatively, and quantitatively. The results of flowering phenology observations showed that petunia flower development occurred over an average period of 37 days. Based on the characterization of the morphological structure of the flower, the average length is 72 mm and the diameter is 42 mm. It is categorized as a complete flower because it has a main organ consisting of five petals with an average diameter of 42 mm, five petals with an average length of 14 mm, and an average diameter of 16 mm. Furthermore, the genitals of the flower, namely the stamens, are five in number, and there is one pistil in each flower.]]>

<![CDATA[Telah dilakukan pengabdian kepada masyarakat di SMP Negeri 1 Muaro Jambi, pengabdian ini dilakukan terhadap guru-guru IPA. Dari hasil wawancara dengan guru tersebut pembelajaran optik selama ini belum diajarkan melalui praktikum dan percobaan, karena berbagai faktor yang kurang mendukung sehingga praktikum percobaan fisika sering tidak dilakukan, kendala yang paling banyak dijumpai adanya keterbatasan alat-alat praktikum yang tersedia. Untuk memahami konsep yang baik, disamping mempelajari teori juga harus disertai dengan praktikum agar dapat memahami konsep dengan baik dan juga menambah minat belajar siswa. Untuk mengatasi masalah tersebut perlu dilakukan pengenalan alat-alat optik dan pada akhirnya melakukan praktikumnya agar guru-guru dapat lebih terampil dan memiliki khasanah yang luas dalam mengajarkan materi optik tersebut. Berdasarkan kegiatan pengabdian kepada masyarakat yang telah dilaksanakan dapat disimpulkan bahwa kegiatan pengabdian sangat dibutuhkan bagi pihak sekolah terutama SMP Negeri 1 Muaro Jambi, dengan adanya kegiatan pengabdian ini, guru IPA sangat terbantu dengan adanya pengenalan alat-alat optik dan mendapat menambah inspirasi bagi guru untuk melakukan praktikum alat-alat optik di sekolah.]]>
