Abstract

Darul Fithrah Islamic Boarding School (Ponpes DF) is a tahfiz Al-Qur'an-focused Islamic boarding school with education levels from kindergarten to high school. This Islamic boarding school has various active extracurriculars, one of which is hydroponic extracurriculars. This extracurricular is very useful for improving students' abilities. However, currently, there are still various shortcomings, one of which is related to the capability and application of technology in gardens. In order to fulfill this, training activities are carried out in this community service, and automatic nutrient control technology in hydroponics is applied. The training is aimed at students and hydroponic extracurricular administrators. This training activity focuses on explaining various methods and types of plants that can be cultivated using the hydroponic method, then training on the use of automatic nutrient control in hydroponic gardens. Based on the results of training and the application of automatic nutrient control technology, students and administrators can understand various types of hydroponic cultivation methods and then know how to plant various other types of plants that can be cultivated so that there can be a greater variety of plants that can be planted in the garden. Finally, based on the results of the application and training of automatic nutrient control technology, the students and administrators consider that the application of this technology is beneficial in the process of monitoring and maintaining plant quality.

Abstract

Beton adalah material konstruksi yang diperoleh dari pencampuran pasir, kerikil/agregat kasar, semen serta air. Di sisi lain penggunaan kerikil yang merupakan sumber daya alam yang tidak dapat diperbaharui secara terus menerus sebagai bahan beton dikhawatirkan merusak lingkungan. Dalam mengatasi isu itu maka riset tentang konstruksi hijau (Green Construction) mulai digalakkan dengan salah satunya adalah pemanfaatan limbah batu kerajinan di Padalarang. Tujuan penelitian adalah mengetahui komposisi optimum agregat kasar dari limbah pada beton sehingga menghasilkan kuat tekan yang maksimum. Tahapan Pertama dalam penelitian ini adalah pengumpulan data selanjutnya adalah analisis Laboratorium meliputi uji sifat teknis material penyusun beton yang meliputi pasir , kerikil alami dan kerikil dari limbah batu kerajinan. Selanjutnya proses mix desain dimana penelitian dilakukan dengan 30 benda uji dengan komposisi antara split dan limbah adalah 100% : 0%, 80% : 20%, 60% : 40%, 40% : 60%, 20% : 80% dan 0 % :100 %, masing masing komposisi berjumlah lima benda uji. Pengujian meliputi berat jenis, kuat tekan dan modulus elastisitas beton. Hasil penelitian menunjukkan kuat tekan maksimum diperoleh pada proporsi 40% split dan 60% limbah yaitu 14.35 MPa. Modulus elastisitas maksimum diperoleh pada proporsi 20% split dan 80% limbah yaitu 18367.8 MPa.
