Abstract

Tulangan bambu yang sudah dibentuk biasanya mempunyai permukaan licin hampir 50%. Namun, pada permukaan licin tulangan bambu adalah letak kekuatan serat yang paling tinggi. Tujuan penelitian ini adalah untuk meningkatkan kuat tarik tulangan bambu dengan memasang klem selang pada tulangan bambu. Metode yang digunakan adalah uji pull-out tulangan bambu dengan dimensi 15x15 mm2 yang ditanam pada silinder beton berukuran diameter 150 mm dan tinggi 300 mm. Pengujian dilakukan dengan mesin UTM kapasitas 500 kN. Hasil pengujian menunjukkan bahwa kuat tarik cenderung linier positip seiring dengan meningkatnya jarak pemasangan klem selang. Tulangan bambu dengan treatmentt lapis perekat dan klem selang jarak 5 cm mempunyai kuat tarik tertinggi sampai 400,35% dari tulangan bambu normal. Penggunaan perekat pada tulangan bambu harus dilakukan sebagai lapis kedap air dan mengurangi permukaan licin.

Abstract

Mayoritas kegagalan balok beton bertulang bambu adalah kegagalan slip. Slip terjadi pada tulangan bambu disebabkan oleh kuat lekat antara tulangan bambu dengan beton tidak sempurna. Kuat lekat tidak sempurna akibat adanya perbedaan modulus elastisitas beton dan bambu.  Tujuan penelitian ini adalah menganalisa pengaruh jarak klem selang terhadap kuat lekat pada balok beton bertulang bambu. Balok yang digunakan adalah balok beton bertulang tunggal dengan ukuran 75 mm x 150 mm dengan panjang 1100 mm. Jenis bambu yang digunakan adalah bambu petung (Dendrocalamus asper). Variasi luas tulangan bambu adalah 150 mm2, 300 mm2, dan 450 mm2 dengan jarak klem selang 0 cm, 15 cm, 20 cm, dan 25 cm. Metode pengujian balok adalah metode empat titik. Analisis data pengaruh jarak klem selang terhadap kuat lekat dianalisis dengan ANOVA dua arah. Hasil pengujian menunjukkan bahwa variasi jarak klem-selang (s) tidak mempunyai pengaruh yang signifikan terhadap kuat lekat (u), sedangkan untuk variasi luas tulangan (Ab) mempunyai pengaruh yang signifikan terhadap tegangan lekat (u). Namun jika diuji secara parsial, pengaruh jarak klem-selang (s) terhadap kuat lekat (u) mempunyai pengaruh signifikan.

Abstract

Sukogidri Village is an underdeveloped village towards an independent village. The topography of the village is in the form of highlands and hills where many bamboo plants grow which is great potential to be utilized. However, bamboo has not been used strategically and has not been of high selling value. One of the benefits of bamboo is used as concrete reinforcement. The basic problem is that the village community, especially the craftsmen, do not yet know about bamboo as concrete reinforcement, so they need mentors and motivators to increase community empowerment. The objectives of this activity include the achievement of the level of empowerment of members of the creative community group and the growth of the entrepreneurial spirit of the craftsmen through counseling and training. Methods for implementing the activities include: (1) providing guidance and training on how to produce concrete reinforcement from bamboo for the structure of simple houses; (2) providing training on bamboo treatment as concrete reinforcement; (3) providing counseling about the marketing and economic prospects of bamboo. The results achieved are the level of empowerment of members of the Community Creative Group increases. From the results of practical and theoretical tests, 80% of the builders did not make mistakes, and only 19.70% made mistakes. As many as 19.70% of the builders are skilled workers but still, need further assistance. And 80.30% of the builders are skilled workers who are independent and do not need further assistance. It can be concluded that training and guidance on bamboo as concrete reinforcement can improve the entrepreneurial spirit of the community with the formation of the Community Creative Group.

Abstract

Jember Regency is one of the regencies prone to earthquakes. This disaster has caused a number of damaged buildings in various affected areas. The buildings affected by the earthquake were simple houses built by village builders. They generally do not understand how earthquake shear forces behave in the houses they build. The objective of this activity was to provide the masons with the skills to retrofit simple houses made of unreinforced masonry walls by applying ferrocement technology so that the bearing capacity against earthquake-induced shear forces would be higher. The ferrocement training was conducted in Sukogidri Village, Ledokombo, Jember. This activity was carried out by socialising and coordinating, providing training, conducting group strengthening and evaluation. The average score obtained by individual builders during the pretest was between 39.7 and 40.1. After the training, the average score of personal builders was between 77.6 and 80.3. The overall ability of builders before the training activities was 40.03. The overall ability of the builders after the training was 78.77. The increase in the average ability of builders personally when compared between before and after training with a value between 37.4 to 40.3. Meanwhile, the overall improvement of the builders after the Community Partnership Empowerment (PKM) programme was 38.75. This indicates that the training was very appropriate to improve the ability of builders to apply ferrocement technology to retrofit simple earthquake-damaged houses.

Abstract

ABSTRAKSelama ini, warga Desa Sukogidri masih belum memiliki kepedulian untuk memproses sampah yang berasal dari kegiatan rumah tangga. Untuk mengantisipasi kelangkaan pupuk, hilangnya kesuburan tanah dalam waktu jangka panjang dan mudahnya serta murahnya penggunaan teknologi takakura, maka masyarakat Desa Sukogidri perlu diberikan edukasi mengenai pentingnya menggunakan pupuk organik serta memberikan pelatihan pembuatan sampah organik dengan metode takakura. Tujuan kegiatan ini adalah pertama, masyarakat memiliki pola pikir bahwa sampah organik dalam waktu jangka panjang dapat mempertahankan dan bahkan membuat tanah menjadi bertambah subur, sehingga masyarakat tidak tergantung lagi pada pupuk buatan. Tujuan kedua adalah agar masyarakat terampil mengolah sampah organik sisa rumah tangga dan sampah organik yang berasal dari lingkungan sekitar menjadi pupuk organik dengan teknologi takakura. Tahapan pelaksanaan kegiatan dilakukan mulai dari observasi, koordinasi lapangan, menyiapkan peralatan, menyiapkan bahan, penyuluhan penggunaan pupuk organik, praktek membuat pupuk organik, penyerahan peralatan dan bahan serta penguatan kelompok masyarakat.  Penguatan kelompok masyarakat ini dilakukan dengan cara menunjuk Koordinator Desa, Koordinator Dusun, Koordinator Dasawisma serta ketua kelompok Penilaian dilakukan dalam skala 0 sampai 100. Nilai 0 dianggap sangat tidak mampu dan nilai 100 dianggap sangat mampu. Kegiatan Program Kemitraan Masyarakat Stimulus (PKMS) ini telah memberikan dampak positif dari kategori kurang mampu menjadi mampu bagi peserta pada khususnya dan kepada masyarakat sukogidri pada umumnya dalam memahami manfaat pupuk organik maupun dalam pembuatan pupuk organik.            Kata kunci: pupuk organik; takakura; sampah organik; lahan pertanian. ABSTRACTSo far, the residents of Sukogidri Village still do not have the awareness to process waste from household activities. To anticipate the scarcity of fertiliser, the loss of soil fertility in the long term and the easy and cheap use of takakura technology, the people of Sukogidri Village need to be educated about the importance of using organic fertiliser and provide training in making organic waste using the takakura method. The objectives of this activity are first, the community has the mindset that organic waste in the long term can maintain and even make the soil more fertile, so that people are no longer dependent on artificial fertilisers. The second goal is for the community to be skilled in processing organic waste from households and organic waste from the surrounding environment into organic fertiliser with takakura technology. Stages of activity implementation were carried out starting from observation, field coordination, preparing equipment, preparing materials, counselling on the use of organic fertiliser, practice making organic fertiliser, handing over equipment and materials and strengthening community groups. The assessment was carried out on a scale of 0 to 100. A score of 0 is considered very incapable and a score of 100 is considered very capable. This Stimulus Community Partnership Program (PKMS) activity has had a positive impact from the category of less capable to capable for participants in particular and to the Sukogidri community in general in understanding the benefits of organic fertiliser and in making organic fertiliser. Keywords: organic fertiliser; takakura; organic waste; farmland
