Abstract

Lau Bakeri Village is one of the villages in Kutalimbaru District, Deli Serdang Regency, where 30 families of them run a business of oyster mushroom cultivation according to the humidity in the area. The service partners have been running the oyster mushroom cultivation business for 10 years, most of which are still done manually, including compaction of planting media (baglog) which takes a long time and requires hired workers with a salary of Rp. 200,000, - per day. The demand for mushrooms is still quite open, but due to limited land and labor, not all of them can be served. Making baglog pressing machines and training on the use of machines are expected to be solutions that can overcome problems for oyster mushroom cultivators. At the time of giving the tools and socializing the use of this mushroom baglog pressing machine, the community was very welcoming, and hoped that this community service partnership like this would continue

Abstract

The Community Partnership Program (PKM) is one of the means of service to express ideas in dealing with problems that arise in the community. We propose this PKM with the aim of helping MSMEs who are having difficulties in developing their businesses. One of these MSMEs is located in Sukaraya Village, Hamlet Amal with a trade name, namely Sumber Sehat which is a target source for PKM implementation partners which can be categorized as an economically productive community. The problems faced by healthy resource partners are inconvenient places to live, such as leaky and rickety zinc canopies, wooden poles that are porous due to being eaten by termites and slanted poles and cement floors and do not have sales management. These SMEs sell food items such as chicken, carp, catfish, eel, tilapia and vegetables. Therefore, the purpose of this service is to help partners to repair canopies and poles that are no longer functioning properly. The target to be achieved in this PKM is that the place to trade these materials can become a comfortable place for consumers. The solution given to solve the problem to achieve the target, then repair the trading place. Partners really hope that their trading place can be repaired and is suitable for reuse as before. By providing canopy assistance and management of healthy sources of business, it is possible for partners to be able to sell community food by having a comfortable and safe trading place. At the time of making the canopy and training in business management, the community was very welcoming, and hoped that the community service partnership could continue in the future

Abstract

Program Kemitraan Masyarakat (PKM) adalah salah satu sarana pengabdian untuk mengemukakan ide-ide dalam menghadapi masalah yang timbul di masyarakat. Kami mengusulkan PKM ini dengan tujuan yang mana dapat membantu para UMKM  yang sedang kesulitan dalam mengembangkan usaha mereka. Salah satu UMKM ini terletak di Desa Sukaraya Dusun Amal dengan nama dagangnya yaitu Sumber Sehat yang mana menjadi sumber sasaran bagi mitra pelaksanaan PKM dimana dapat dikategorikan sebagai masyarakat yang produktif secara ekonomis. Permasalahan yang dihadapi mitra sumber sehat yaitu tempat tinggal yang kurang nyaman seperti kanopi seng yang sudah bocor dan reyot, tiang kayu yang sudah keropos akibat dimakan oleh rayap dan tiangnya juga sudah miring serta lantai semen serta belum memiliki manajemen penjualan. UMKM ini menjual bahan pangan seperti, ayam potong, ikan mas, ikan lele, ikan belut, ikan nila dan juga sayur mayur. Oleh karena itu, tujuan pengabdian ini adalah membantu mitra untuk memperbaiki kanopi dan tiang yang sudah tidak berfungsi lagi dengan semestinya. Sasaran yang ingin dicapai dalam PKM ini adalah agar tempat berdagang bahan tersebut dapat menjadi tempat yang nyaman bagi konsumen. Solusi yang diberikan untuk menyelesaikan permasalahan untuk mencapai sasaran, maka dilakukan perbaikan tempat berdagang tersebut. Mitra sangat berharap agar tempat berdagangnya dapat diperbaiki dan layak digunakan kembali seperti awalnya. Dengan memberikan bantuan kanopi dan manajemen usaha sumber sehat dimungkinkan mitra mampu berjualan bahan pangan masyarakat dengan memiliki tempat berdagang yang nyaman dan aman. Pada saat pembuatan kanopi dan pelatihan manajemen  usahamasyarakat sangat menyambut baik, dan berharap kemitraan pegabdian masyarakat dapat berlanjut kedepannya.

Abstract

Desa Lau Bakeri merupakan salah satu desa di Kecamatan Kutalimbaru, Kabupaten Deli Serdang dimana 30 KK diantaranya menjalankan usaha budi daya jamur tiram yang sesuai dengan kelembaban di daerah tersebut. Mitra pengabdian sudah 10 tahun menjalankan usaha budidaya jamur tiram yang sebagian besar masih dilakukan secara manual, termasuk pemadatan media tanam (baglog) yang memakan waktu cukup lama dan butuh pekerja upahan dengan gaji Rp. 200.000,- per hari. Permintaan jamur masih cukup terbuka akan tetapi karena keterbatasan lahan dan tenaga kerja belum semua dapat dilayani. Pembuatan mesin pengepres baglog dan pelatihan penggunaan mesin diharapkan dapat menjadi solusi yang dapat mengatasi permasalahan pada pembudidaya jamur tiram. Pada saat pemberian alat dan sosialisasi penggunaan mesin pengepres baglog jamur ini, masyarakat sangat menyambut baik, dan berharap kemitraan pegabdian masyarakat seperti ini terus berlanjut.

Abstract

Biodiesel is a potential energy source that has attracted attention recently because it can be produced from renewable energy sources and produces low pollutants. Biodiesel is produced by transesterifying edible or non-edible vegetable oils using a catalyst. Homogeneous catalytic processes have disadvantages, such as the catalyst residue cannot be reused. Therefore, heterogeneous or solid catalysts are used, which can be easily separated from the reaction mixture by filtration and reused. A waste cockle shell can be used as a green base catalyst to synthesize waste cooking oil into methyl ester (WCME). The free fatty acid content of used cooking oil (2.19% wt.) was initially reduced to 0.11% wt., using a methanol-oil ratio of 6:1, waste cockle shell 2% wt., reaction time 60 minutes and temperature 60 oC. The effectiveness of the developed waste cockle shell contains high CaO. The results of this study indicated the potential of clam waste cockle shells and used cooking oil as a source of raw materials available in the community for biodiesel production.
