Abstract

Batteries are one source of electrical energy that is still an important need in everyday life, especially for electronic equipment. Batteries are often used for daily activities, including for TV remotes, wall clocks, flashlights, and others. However, battery waste is very dangerous for the environment because it contains hazardous materials and requires proper handling to deal with it. One of them is the procurement of alternative batteries that are more environmentally friendly. Battery waste can be recycled using natural materials, one of which is using waste from banana peels. Banana peels contain ionizing properties and conduct electricity, making them suitable for use as an electrolyte paste that has optimal battery life. The processing of leather waste into alternative batteries (biobatteries) is carried out with partners from the residents of Sidotopo Wetan Village, Kenjeran District, Surabaya, as a community service program through three stages, namely the preparation, socialization, and practice stages. Then in the practical session, experiments were also carried out with the aim of knowing the voltage generated from the biobattery and the durability of the biobattery made from banana peel waste. In the experimental results in the practical session, it was found that banana peel waste can deliver electricity, so it can be used for electrolytics in commercial batteries which may be used as biobatteries. It is hoped that through this service program, it can provide provisions for community partners in overcoming battery needs through their own production to reduce the cost of purchasing batteries, as well as being able to update science and technology, so that community partners are able to create prosperous and competitive families. Baterai merupakan salah satu sumber energi listrik yang masih menjadi kebutuhan penting dalam kehidupan sehari-hari terutama untuk peralatan elektronika. Baterai seringkali digunakan untuk kegiatan sehari-hari, diantaranya untuk remot TV, jam dinding, senter, dan lain-lain. Namun, limbah baterai sangat berbahaya bagi lingkungan karena mengandung bahan berbahaya dan beracun yang memerlukan penanganan yang tepat untuk mengatasinya. Salah satunya dengan pengadaan baterai alternatif yang lebih ramah lingkungan. Limbah baterai dapat didaur ulang menggunakan bahan alami salah satunya menggunakan limbah dari kulit pisang. Kulit pisang memiliki kandungan yang dapat terionisasi dan menghantarkan listrik, sehingga cocok digunakan sebagai pasta elektrolit yang memiliki daya tahan baterai yang optimal. Pengolahan limbah kulit pisang menjadi baterai alternatif (biobaterai) dilakukan bersama mitra warga Kelurahan Sidotopo Wetan, Kecamatan Kenjeran, Surabaya, sebagai program pengabdian masyarakat melalui tiga tahapan yaitu tahap persiapan, sosialisasi, dan praktik. Kemudian di sesi praktik juga dilakukan eksperimen dengan tujuan mengetahui tegangan yang dihasilkan dari biobaterai serta daya tahan biobaterai yang berbahan dari limbah kulit pisang. Pada hasil eksperimen di sesi praktik didapatkan hasil bahwa limbah kulit pisang dapat mengantarkan arus listrik, sehingga dapat digunakan untuk menggantikan elektrolit pada baterai komersil yang berpotensi sebagai pembuatan biobaterai. Diharapkan melalui program pengabdian ini dapat memberikan bekal kepada mitra warga dalam mengatasi kebutuhan baterai melalui produksi sendiri untuk menekan biaya pembelian baterai, serta dapat menjadi pemutakhiran ilmu pengetahuan dan teknologi, sehingga mitra warga mampu menciptakan keluarga sejahtera dan berdaya saing.

Abstract

Banana (Musa sp) is a priority fruit commodity which is able to be a supporting factor for the welfare of the community. Bananas are easily damaged fruits, so the selling value of bananas will decrease according to the age of the fruit after harvest. Storage of fruit in various temperatures also has not been able to extend the banana fruit shelf life. The potential of bananas as a food source that can be stored can be done through the processing of bananas into banana flour. The banana flour training carry out at the Biology Laboratory of FMIPA UNJ with a participant from RW 03 and 05 Rawamangun District. The making of banana flour is done in two technique. The first technique is to peel the skin previously then the fruit is immersed in a 10% salt solution for 10-20 minutes.  The second technique is done by steaming raw bananas for 10-20 minutes before stripping and soaking in a salt solution. Bananas that have been peeling are then slicing thinly to make cassava chips. Banana cassava is dried using sunlight for 2-3 days or dried in an oven at 150 °C for 2 days.  Dried cassava is mashed using a household scale flouring miller tool. Flour produced from the oven drying process is brownish-white, whereas by drying sunlight it is bone-white with a very fine texture. The results of the test carbohydrate content of banana flour produced had 56.72 g / 100 g starch content, 23.09 g / 100g amylose content and 33.63 g / 100 g amylopectin content.  The activity ended with giving banana flour samples produced in this activity and providing flour as an aid tool for community entrepreneurship.

Abstract

Abstract Until this day, the use of yard land is still not optimal, thus the development of various innovations related to home yards is also limited. The houses in the area of neighborhood (RT) 11 Hamlet (RW) 03 Rawamangun Urban Village East Jakarta have narrow yards. One alternative to increase limited space productivity is through the use of simple hydroponic techniques. The principle of floating raft hydroponics is growing plants with water as a medium while floating on a nutrient solution. Its simple implementation allows it to be applied to limited land space. The purpose of this community service is to convey information and training on the use of the floating raft hydroponic system which can be used as an alternative to increase the productivity of the pakcoy vegetable plant. Community service activities were carried out through lectures, discussions and direct demonstrations of cultivating pakcoy with a floating raft hydroponic system in the land of the residents of RT 11 RW 03. Presentations were carried out by explaining an easy and practical method to cultivate hydroponic pakcoy plants and provide an explanation of the benefits of hydroponic plants. The pakcoy cultivation consists of 4 stages, namely the stage of seeding, transfer to floating rafts, maintenance and harvesting. The implementation of the activity went smoothly and received very positive responses from the participants, seen from the number of questions received and the enthusiasm of the participants during the activity. The participants gave very positive response to the information provided. The activity ended with the provision of hydroponic pakcoy vegetables, floating raft kits, and transplanted seeds into floating rafts. Abstrak Pemanfaatan lahan pekarangan pada saat ini masih belum optimal, sehingga pengembangan berbagai inovasi yang terkait dengan lahan pekarangan juga terbatas. Wilayah Rt 11 Rw 03 Kelurahan Rawamangun, merupakan salah satu wilayah di Jakarta Timur yang memiliki lahan pekarangan yang sangat sempit. Salah satu alternatif yang dapat dilakukan dalam meningkatkan produktivitas lahan yang terbatas yaitu melalui pemanfaatan teknik hidroponik yang sederhana. Hidroponik rakit apung memiliki prinsip menanam tanaman dengan media air dalam keadaan diapungkan di atas larutan nutrisi. Implementasinya yang sederhana sangat memungkinkan untuk diterapkan pada lahan yang terbatas. Tujuan dari pengabdian masyarakat ini adalah menyampaikan informasi dan pelatihan penggunaan sistem hidroponik rakit apung yang dapat dijadikan sebagai alternative untuk meningkatkan produktivitas tanaman sayuran pakcoy. Kegiatan pengabdian dilakukan melalui ceramah, diskusi dan demonstrasi langsung budidaya tanaman pakcoy dengan sistem hidroponik rakit apung di lahan pekarangan warga Rt 11 Rw 03. Kegiatan presentasi dilakukan dengan penjelasan cara budidaya tanaman pakcoy hidroponik yang mudah dan praktis serta penjelasan akan manfaat dari tanaman hidroponik. Pembuatan budidaya tanaman pakcoy terdiri dari 4 tahapan yaitu tahap pembibitan, pemindahan ke bak rakit apung, perawatan dan panen. Pelaksanaan kegiatan berjalan lancar dan mendapat tanggapan yang sangat positif dari para peserta, dilihat dari banyaknya pertanyaan yang muncul serta antusiasme peserta selama kegiatan. Respon peserta terhadap informasi yang diberikan sangat baik. Kegiatan diakhiri dengan pemberian tanaman sayuran pakcoy hasil hidroponik, kit rakit apung, dan bibit yang sudah dipindah tanam kedalam bak rakit apung.

Abstract

Pari Island is one of the islands among the Thousand Islands group, about 46.32 km from the center of Jakarta with a total area of 310,000 km2 has high biodiversity, one of which is from the macroalgae group. Although macroalgae are a source of high biodiversity, the utilization of macroalgae is still very minimal to do because of the lack of education in the community about the types and benefits of macroalgae found in waters. This study aims to determine the diversity of macroalgae in Rengge Beach, Pari Island, Kepulauan Seribu, Jakarta so that later the community can find out more information about the types, characteristics, and potential utilization of macroalgae. The research was conducted in December 2022 using the benthic belt transect method with a total of 5 stations, carried out by drawing a line from the shoreline inland with a transect length of 100 m and a width of 10 m (5 m to the right and left sides), a monitoring area of 1 km² (10x100 m) between stations. Samples were taken and identified to the species level at the Plant Structure and Development Laboratory, Biology study program, Jakarta State University, Jakarta. Observations include several characteristics both morphologically and anatomically. The results showed that there were five species of macroalgae that could be identified, namely Halimeda sp, Gracilaria sp, Turbinaria sp, Padina sp, and Sargassum sp, therefore it can be concluded that there are only five genera of macroalgae in this place. This research needs more development that can provide more benefits, one of which is to develop the research area and further identify the types of macroalgae obtained to find out more specific information about the potential of macroalgae.
