Abstract

Permasalahan pengelolaan sampah merupakan permasalahan yang dialami oleh seluruh umat manusia. Sampah yang dihasilkan mencakup sampah organik dan sampah anorganik. Generasi zaman milenial terkhusnya generasi-Z adalah generasi yang suka dan peduli terhadap lingkungan. Generasi ini masih mampu untuk diarahkan untuk mencintai lingkungan dengan memberikan edukasi tentang pemisahan sampah organik dan sampah anorganik, pertanian organik, seperti pembuatan pupuk organik, mengintegrasikan pertanian dengan peternakan organik. Pengabdian dilakasanakan di panti Asuhan Sinar Indah Cahaya. Kegiatan pengabdian diikuti 30 orang anak panti asuhan, 3 orang pengurus panti asuhan. Pengabdian ini mengedukasi tentang pemisahan sampah organik dari sampah anorganik perlu dan penting untuk diberikan sejak dini. Pengetahuan sejak dini akan meningkatkan kesadaran dan afeksi mereka untuk peduli pada lingkungan. Pengenalan dan pemahaman akan bahan-bahan (limbah) organik serta teknologi sederhana untuk pengolahan sampah dengan penggunaan komposter sejak dini serta kesadaran yang tinggi akan menarik minat generasi milenial untuk menuju pertanian organik bahkan sampai pada integrated farming. Hasil Kegiatan adalah anak-anak panti dapat membedakan sampah organik dan anorganik dapat membuat mol dari bahan-bahan sederhana mampu, membuat pupuk kompos dari sampah organik dan menggunakan komposter

Abstract

The location for the construction of the GBKP Bukit Inculturative Building, Berastagi sub-district, is a high-risk location because it is located in an area prone to earthquakes, high ground and prone to landslides. Construction of the GBKP Bukit District Inculturative Building. Berastagi was created as a place of worship which is filled with worshipers every day. Therefore, the planning and construction of the type of substructure (foundation) needs to be carefully calculated so that the building does not subside or collapse. The purpose of this research is to determine the cost comparison between planning and implementation costs for drill pile foundation work in the field and to determine the carrying capacity of the drill pile foundation on the GBKP Bukit District Inculturative Building construction project. Berastagi, knowing the dimensions of the reinforcement used in the foundation of the GBKP Bukit Kec Inculturative Building. Berastagi and knowing the method of carrying out construction work and the planned cost budget (RAB) for the drill pile foundation at the GBKP Bukit Inculturative Building, Berastagi District. This research is planned to target outputs in the Juitech Journal, as mandatory outputs and the results of this research will produce additional outputs in the form of teaching materials and will also be discussed before publication. The Technology Readiness Level (TKT) of the proposed research is at level 2 where analysis is carried out by comparing the planning cost plans and treatment cost budgets in the field.

Abstract

Cayenne pepper is a commodity that is quite high in demand in Indonesia. The problem in chili nurseries is to ensure that the plants grow vigor after the transplanting process is carried out. For this reason, it is necessary to provide vitamins to accelerate the adaptation process so that chili plants can grow optimally. To overcome this problem, in this study the application of vitamin B1 (thiamine) was carried out at the beginning of transplanting cayenne pepper seedlings from the nursery. The purpose of this study was to determine the effect of the application of vitamin B1 on cayenne pepper seeds and the best concentration of vitamin B1. This research will be carried out for three months, from early June to the end of August 2023. The research will be conducted in Kelurhan Sidomulyo, Kecamatan Medan Tuntungan, Kota Medan. The research design was a completely randomized design with 1 factor and 3 replications. The treatment factor was the concentration of vitamin B1 with 4 levels. V0: control; V1: 0.5 ml/l vitamin B1; V2: 1 ml/l vitamin B1; and V3: 1.5 ml/l vitamin B1. The results showed that the administration of vitamin B1 (thiamine) during transplanting had an effect on the growth of cayenne pepper seedlings.

Abstract

AbstractMelon is a fruit plant that has a high nutritional value. A limited agricultural land encourages the application of alternatives planting method and utilizes local materials around the community as potential planting media towards resulting a high-yielding variety. One of the cultivation techniques is the use of the hydroponics system. The objective of this study is to determine the most suitable planting medium for melon varieties to be planted hydroponically. This research was conducted in the greenhouse at the sub-district of Medan Tuntungan in the city of Medan during May to August 2017. This research used Randomize Complete Block Design Factorial with 3 replications. The use of planting media consisted of charcoal husk, cocopeat, sawdust and sand; whereby the treatment of varieties consisted of Aramis F1, Amanta F1 and Red Aroma. The results showed that the best medium for hydroponics melon is charcoal husk highlighting significant result onto the plant height, number of leaves and fruit weight of crops, from the use of charcoal husk media.Keywords: hydroponic, soilless culture, melon, medium and variety

Abstract

Alang-alang (Imperata cylindrica) and Saliara (Lantana camara) are dominant weeds in several crop cultivation areas, so that when control is carried out, waste from both weeds will be produced in large quantities. Management of waste from both weeds can be done by utilizing it as a more environmentally friendly bioherbicide. Bioherbicide application is carried out pre-growth so that control is carried out faster and attacks newly germinated weed seeds, so that weeds do not appear on the surface and weed control activities will be more efficient. Alang-alang is the most dangerous weed and is highly avoided because it contains allelochemical compounds that can inhibit the growth of the main plant, this compound is found in all parts of the weed but is found most in the roots. Saliara also has a high content of allelochemical compounds which causes a distinctive aroma from its leaves. The allelochemical content of both weeds can be used as active ingredients in bioherbicides and is effective in controlling other weed species. Several studies have reported that bioherbicide extracts from both weeds are effective in inhibiting weed growth so that they can be used as an alternative to herbicides. However, bioherbicide application must be carried out with the right technique and concentration so as not to interfere with and inhibit the growth of the main plant.
