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.

Abstract

As a megadiversity country, Indonesia is home to a large number of flora and fauna, one of which is the butterfly. The Bogor Botanical Garden, situated at the center of Bogor City, not only serves as a green open space but also as a conservation area for plants and animals composed in it.  This study aimed to assess the diversity of butterfly species in Teijsmann Park and Soedjana Kassan Park, Bogor Botanical Garden through inventory and identification.  Sampling was carried out at spots that were 100 meters apart from each other on a walked-line transect defined at the two parks. The diversity parameters assessed and analyzed are relative abundance, relative frequency, Shannon-Wiener (H’) diversity index, Evenness index (E), and dominance.  In a total of 202 sample individuals, there were identified 38 species of butterflies belonging to 5 families namely Papilionidae, Pieridae, Nymphalidae, Lycaenidae, and Hesperiidae. The highest abundance found in Teijsmann Park is Ypthima philomela from the Nymphalidae family and Zizina otis from the Lycaenidae family. Species with the highest frequency are Junonia hedonia and Ypthima philomela from the Nymphalidae family. On the other hand, the highest frequency and abundance found in Soedjana Kassan Park was Leptosia nina from the Pieridae family. Teijsmann Park showed a slightly higher value of diversity and evenness indexes (H'=2.62, E=0.84) when compared to Soedjana Kassan Park (H'=2.50, E=0.76).

Abstract

Strawberry (Fragaria sp.) is a horticultural plant originating from the Americas. Strawberries have a distinctive sweet and refreshing taste, and contain lots of vitamins and antioxidants that are useful for body health. But strawberries are also easily damaged. This damage can be caused by spoilage microorganisms such as bacteria and fungi that can grow if conditions permit such as the presence of appropriate temperature and humidity conditions. In this experiment, aims to isolate pathogenic microorganisms that cause disease in symptomatic strawberries and prove that these pathogens actually cause disease using Koch's Postulates method and then descriptive analysis is carried out. From the experimental results, it was found that soft rot disease in strawberries was characterized by rotten fruit parts that looked wet, slightly brownish in color, slimy, there were fine white threads and emitted a foul odor with a percentage of IP (disease occurrence) of 100% and KP (disease severity) of 92.66% where based on the score the damage was the highest.

Abstract

The potato plant (Solanum tuberosum L.) is a perennial crop that contains high amounts of carbohydrates, minerals, and vitamins in its tubers, making it a carbohydrate-rich alternative food to rice or corn. One of the diseases that often appear on potato plants is potato rot caused by pathogenic molds. This study aims to isolate and characterize pathogenic fungi that cause blight on potato tubers based on Koch's Postulates. Potato pathogenic molds were isolated from potato tubers that had been rotted, then the molds were grown on PDA and purified twice. The purified isolates were then inoculated onto 30 healthy potato tubers and incubated for 7 days. Healthy potato tubers experienced the same symptoms as potato tuber rot. The isolated pathogenic fungi were then characterized so that the pathogenic fungi of Phytophthora infestans were obtained. In this study, Koch's Postulate method was successfully applied to isolate and characterize the pathogenic fungi that cause potato tuber rot. The pathogenic fungi caused a potato tuber rot disease incidence value of 100% with a disease severity value of 60.7%. The two factors that determine the disease incidence and disease severity values are internal factors (genes and traits of the pathogen) and external factors (environment).
