Abstract

In Karang Kelok hamlet, West Monjok, Mataram, there are currently 2 Home Industries (IRT) that make tofu and are known as Javanese tofu. Because the texture is different from the Lombok tofu in general, this tofu is in great demand by the wider community. So the demand in every day is very much. One of them belongs to Tin's mother. This IRT is able to absorb 3 workers. Every day able to spend 60 kg of soybeans. In producing the tofu, this IRT still uses the traditional method, especially when pressing the tofu is still done by overlapping 1-3 pieces of stone with different weights. Pressing in this way has weaknesses, including security and work safety issues. This condition is also one of the obstacles to be able to produce more tofu products. This pressing is done one by one and in a row, so it also takes up a wider area. Based on these problems, it is necessary to plan and manufacture hydraulic system tofu pressing tools so that the resulting product increases. The purpose of this service is to get a smaller time and area for pressing in the tofu-making process. The method used is to socialize the use of a hydraulic system tofu press. The results obtained are that this tofu press tool can shorten the average pressing time of 4 minutes and reduce the working area of pressing from 3 meters to 1 meter. And it can also reduce the risk of work accidents due to the fall of the crushing stone.

Abstract

Clean water is one of the main human needs in everyday life is very important to pay attention to its quality. Unfortunately there are still many areas that cannot enjoy clean water as it should. One of the villages that has low water quality is Gegerung Village, Lingsar District, West Lombok Regency. With a variety of natural resources owned by Gegerung Village, the Mataram University Community Service Team took the initiative to make a water filter made from natural palm fiber to overcome existing water problems. Natural materials used include river stone, gravel, palm fiber, and fine river sand. The material is stacked until it fills the tub, then the water is flowed to get clear water. Keywords : Water quality, local resources, palm fiber

Abstract

Beberapa obyek matematika bersifat abstrak. Kajian psikologis menyatakan bahwa anak akan lebih mudah mempelajari hal yang konkrit dibandingkan yang abstrak. Kurangnya minat, motivasi belajar dan dasar konsep matematika membuat siswa SMKN 1 Pringgabaya mengalami kesulitan dalam memahami matematika terutama konsep yang abstrak. Untuk mengatasi hal tersebut, teknologi pembelajaran berbasis aplikasi seperti software Geogebra dapat menjadi solusi efektif. Dengan penggunaan Geogebra ini dimaksudkan agar pembelajaran menjadi interaktif, lebih nyata dan menyenangkan sehingga materi akan lebih mudah dipahami, yang berakibat meningkatkan motivasi belajar. Sebelum pelaksanaan pelatihan, siswa diberikan soal untuk mengukur pemahaman konsep dasar matematika dan juga diberikan kuisioner. Selesai pelatihan peserta diberikan soal dan kuisioner untuk mengetahui motivasi belajar sebelum dan sesudah mengikuti pelatihan dan juga untuk mengetahui apakah pelatihan ini bermanfaat bagi peserta . Dari hasil pengamatan pada saat pelaksanaan pelatihan peserta sangat antusias mengikutinya, terbukti dengan adanya respon dari peserta baik yang bertanya ataupun yang menjawab pertanyaan instruktur terkait jawaban dari soal yang diberikan Dari hasil kuisioner menunjukkan bahwa dengan menggunakan software Geogebra peserta lebih mudah dan cepat dalam menyelesaikan soal-soal geometri, dan juga terdapat peningkatan skor nilai sebelum dan sesudah pelatihan. Kata kunci: Matematika, Geometri, Geogebra, SMKN 1 Pringgabaya
