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

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).

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.
