Abstract

Through Making Indonesia 4.0, The Ministry of Industry responds to the demands of energy needs byinnovative renewable energy development to reduce the consumption of fossil fuels such as petroleum, naturalgas and coal with agricultural biomass waste sources. The aim of this research was to synergize waste from thebiodiesel industry in the form of sterol glycosides with purun waste from creative small-scale enterprises (SMEs)to produce renewable energy as a circular economy. The method applied was in the form of descriptive analysis, followed by identifying and characterizing waste found in the biodiesel industry, as well as various purunwastes, which were collectively sampled every day for 3 months, becoming the basis for developing innovativeproducts. Interviews were conducted on 60 purun craftsmen to confirm the circular economy program beingstudied. Observations were also made in the biodiesel industry and purun craftsmen. Data processing wasobtained from the results of experiments by making briquette products referring to several parameters whichwere the basis for standardizing renewable energy products. The synergy between the two actors, namely theBiodiesel Industry and SMEs in micro-scale circular economy activities, produced environmentally friendly- renewable energy which was very helpful for purun micro and small businesses in Purun Village, Banjarbaru,South Kalimantan. Renewable energy results were from various formulas developed with the main ingredientsderived from purun biomass charcoal and biodiesel industrial waste. The advantage of the product when severalother variables met the SNI standard 01-6235-2000 had a calorific value of 5.809 cal g-1 - 6.598 cal g-1, where5.000 cal g-1 which was the SNI for briquette heat could be exceeded. The calorific value produced is equivalentto bituminous grade coal having a carbon content of above 85%.Keywords: briquettes, calor, purun, sterol glycosides, SMEs

Abstract

Gedung Pendopo Mahligai Iman Kabupaten Tanah Bumbu di Batulicin yang memiliki konstruksi 2 lantai didesain dengan fungsi sebagai kantor dan aula pertemuan. Diduga telah terjadi kegagalan struktur  karena terasa gerakan pada saat penggunaan dalam kondisi beban penuh. Untuk itu dilakukan penyelidikan, untuk kekuatan beton dengan hammer test, deformasi dengan theodolite dan retak dengan mikroskop digital pembesaran 200x. Setelah penyelidikan, dilanjutkan dengan permodelan menggunakan perangkat lunak sehingga dapat diambil kesimpulan kondisi penyebab terjadinya kegagalan. Hasil pengujian menunjukkan bahwa kuat tekan kolom beton memiliki kekuatan sebesar 45MPa serta balok dan plat sebesar 26MPa. Hasil analisa menunjukkan perilaku penurunan plat terbesar adalah 76mm. Pengujian retak struktur pada balok-balok penopang kubah menunjukkan adanya kegagalan struktur dengan beban konstruksi yang berlebih (retak struktural >3mm dengan jumlah yang banyak). Melalui permodelan diperoleh untuk elemen plat mengalami perilaku melendut/deformasi yang besar diprakirakan akibat kesalahan detailing plat, gambar kerja diameter yang 100 mm namun akibat kurangnya pembesian hanya memiliki kekuatan setara dengan diameter 60 mm. Ukuran balok lapangan juga sangat tidak memenuhi syarat yang mana seharusnya adalah 400/300.Dapat disimpulkan bahwa bangunan mengalami degradasi kemampuan. Rekomendasi yang diberikan adalah dilakukan perbaikan pada konstruksi bangunan dengan berbagai metode  perbaikan (retrofitting) beton seperti penggunaan CFR (carbon fibre reionforced), Jacketing pada kolom dan Shortcrete grouting mortar untuk retak yang terjadi. Harus ada maintenance (perawatan) konstruksi bangunan secara periodik agar konstruksi tetap aman dan nyaman untuk dipergunakan oleh publik.

Abstract

In South Kalimantan, coconut shell waste is enormous and is not utilized massively by the local community so that it covers river mouths and even fills the bottom of warehouses and people's houses, and waste/used coconut shells have piled up. This condition causes the river mouth to narrow so that it becomes a problem that is quite disturbing to the local community. Currently, most of the shell waste is used and only used as handicrafts and making briquettes. The use of coconut shell waste for paving blocks is one solution to utilize coconut shell waste into construction materials that support eco-green construction by reducing the cement content. Empowerment of local communities to process coconut shell waste as an eco-paving block construction material is useful in the long term for local communities and supports government programs in implementing the eco-green construction concept. Therefore, the initial step taken was socialization and implementation for small industry partners providing paving blocks in Banjarbaru, South Kalimantan related to manufacturing coconut shell waste as a building material for eco paving blocks. Furthermore, the results of this eco paving block are expected to be further disseminated to local communities to independently make eco paving blocks that can later be used for the construction of public space facilities and green open spaces

Abstract

SMK Negeri 2 Banjarbaru has two competencies from their expertise packages, the Construction and Property Business and Modeling Design and Building Information. However, the academic community lacks knowledge about the procedures for mixing normal concrete and concrete using local waste and the procedures for testing destructive and non-destructive concrete. One of the wastes used is fly ash. Tests for concrete quality control can be carried out by two methods: destructive and non-destructive tests. The destructive test is carried out with a compressive strength test and a tensile strength test of concrete/concrete splitting strength, while a non-destructive test is a hammer test. So that the solution offered is to provide training on planning and quality control of concrete by optimizing the potential of local materials/industrial waste. After the event, the academic community of SMKN 2 Banjarbaru has increased concerning normal concrete mixing and the use of local waste according to SNI standards and quality control of concrete testing in the field using destructive and non-destructive testing methods.

Abstract

Kerusakan pada jembatan biasanya terjadi akibat penurunan mutu material hingga adanya beban benturan pada struktur jembatan. Sehingga perlu dilakukan evaluasi kondisi jembatan tahap awal yaitu penilaian kondisi jembatan. Dilakukan evaluasi nilai kondisi Jembatan Girder Baja Komposit yang terletak di Kabupaten Tapin untuk mengetahui penanganan yang tepat baik untuk proses pemeliharaan, rehabilitasi, atau penggantian elemen jembatan yang rusak. Dua metode penilaian kondisi jembatan yang digunakan untuk evaluasi yaitu metode Bridge Management System (BMS) dan Bridge Condition Rating (BCR). Dari hasil penilaian kondisi, akan dihitung prediksi umur jembatan akibat kerusakan elemen. Berdasarkan hasil penilaian kondisi, diketahui bahwa jembatan memiliki nilai kondisi 2,42 untuk metode BMS dengan usulan perbaikan segera dan nilai kondisi 4,308 untuk metode BCR dengan usulan penanganan rehabilitasi dan tingkat kondisi sedang. Umur jembatan setelah dilakukan penilaian kondisi adalah 35,8 tahun berdasarkan BMS dan 33,9 tahun berdasarkan BCR. Sisa umur jembatan jika umur rencana jembatan 50 tahun adalah 16,1 tahun berdasarkan nilai kondisi BCR. Dari umur jembatan dan nilai kondisi jembatan juga diketahui bahwa jembatan memasuki fase perkembangan kerusakan dan memerlukan penanganan rehabilitasi.Kata kunci: nilai kondisi, umur, kerusakan, jembatan, BMS, BCR
