Peningkatan Pengetahuan Serta Keterampilan Penulangan dan Pengecoran Pada Masyarakat Candi Kuning, Tabanan, Bali
Get PDFReinforced concrete is the most widely used structure compared to steel or wood. Reinforced concrete is generally very easy to work with. The material is very easy to get. It's so easy, it's often done by workers who don't have knowledge and skills about concrete structures. This condition is exacerbated by building owners who do not pay attention to the details of reinforced concrete structures. The owner does not want to pay for the planning consultant or supervisor. The combination of these causes the condition of the building to be not in a safe condition even though in reality there are still many buildings that are being worked on haphazardly and are still in good condition. In the rules of Civil Engineering where safety is the main thing, the conditions above must be corrected. One of the efforts of the academic community to improve this situation is to implement a Community Service Program (PKM) in the form of Technical Guidance (Bimtek) for construction workers. This Bimtek is filled with the provision of theory and practice. The theory presented is knowledge about reinforcement and concrete constituent materials. While the practice consists of working on reinforcement: cutting, bending and assembling reinforcement. For concrete practice consists of mixing and casting concrete. From this Bimtek, the construction workers understand and able to do reinforcement, mix and pour concrete properly. It is hoped that after attending this Bimtek, the construction workers will be able to apply their knowledge and skills to the projects they are working on in order to obtain a good reinforced concrete structure. In its implementation, this Bimtek received a good reception from the Perbekel and the community. In his speech, the Perbekel of Candi Kuning Village hoped that the masons who had attended this Bimtek would become pioneers of correct concrete structure work, be able to increase competitiveness and get increased wages. Through the representatives of the participants, they expressed their gratitude for the knowledge taught and hoped that similar activities could be carried out again.Reinforced concrete is the most widely used structure compared to steel or wood.

Beton bertulang secara umum sangat mudah dikerjakan. Terkadang pemilik bangunan yang tidak mengindahkan detail dari struktur beton bertulang. Kombinasi dari hal tersebut menyebabkan kondisi gedung tidak dalam keadaan aman walaupun pada kenyataannya masih banyak gedung yang dikerjakan serampangan hingga kini masih dalam keadaan baik. Pada kaidah ilmu Teknik Sipil di mana keamanan adalah hal yang utama maka kondisi di atas harus diperbaiki. Salah satu upaya civitas akademika untuk memperbaiki keadaan itu adalah dengan melaksanakan program Pengabdian Kepada Masyarakat (PKM) berupa Bimbingan Teknis (Bimtek) kepada para pekerja konstruksi. Hasil dari bimtek ini para tukang menjadi mengerti, memahami dan dapat mengerjakan penulangan, mencampur dan mengecor beton dengan benar. Diharapkan setelah bimtek ini para tukang dapat mengaplikasikan pengetahuan dan keterampilannya pada proyek-proyek yang dikerjakannya sehingga diperoleh struktur beton bertulangan yang baik. Pada pelaksanaannya, bimtek ini mendapat sambutan yang baik dari perbekel dan masyarakat. Perbekel Desa Candi Kuning dalam sambutannya mengharapkan para tukang yang telah mengikuti Bimtek ini menjadi pionir pekerjaan struktur beton yang benar, mampu meningkatkan daya saing dan mendapatkan peningkatan upah kerja. Melalui perwakilan peserta disampaikan rasa terima kasih atas pengetahuan yang diajarkan dan harapan agar kegiatan serupa dapat dilaksanakan kembali.

Analisis Terhadap Risiko Hukum Pemberian Kredit Perbankan dengan Jaminan Personal Guarantee tanpa Penyertaan Agunan Fixed Asset
No full textBanking institution becomes the main pillar in the implementation of state development activities, therefore the provision of bank credit must pay attention to the risks that will arise, but not only limited to legal risks. Provision of bank credit must be accompanied by the provision of guarantees to carry out security from a legal perspective .In addition to asking for guarantees from customers, bank must also look at the collateral priority scale that will be the guarantee. By making fixed asset collateral as the main scale in granting credit, it is a good first step to mitigate risks, because if the customer defaults on the promise (wanprestasi), the bank gets a reimbursement from the sale (auction) of the collateral goods. However, if the bank makes individual collateral as the main collateral without the inclusion of fixed asset collateral, then the level of risk of granting credit is very high at the time the customer defaults on the promise, so the execution process cannot be instantaneous through the sale (auction) considering that individual collateral does not have a special position. The execution of individual collateral can only be done if there is a court decision with permanent legal force. This research will be presented by the author in normative form.
Keywords: Law Risk, Financing, Personal Guarantee, Fixed AssetLembaga perbankan merupakan pilar utama dalam pelaksanaan kegiatan pembangunan negara, pemberian kredit dalam perbankan harus memperhatikan risiko yang akan timbul, namun tidak terbatas pada risiko hukum. Pemberian kredit bank harus disertai dengan pemberian jaminan untuk melakukan pengamanan dari segi hukum. Selain meminta jaminan dari nasabah, perbankan juga harus melihat skala prioritas agunan yang akan menjadi jaminan, dengan menjadikan agunan fixed asset menjadi skala utama dalam pemberian kredit, merupakan langkah awal yang baik untuk memitigasi risiko, karena apabila nasabah ingkar janji (wanprestasi), bank mendapat penggantian dari penjualan (lelang) atas barang jaminan, tetapi jika bank menjadikan jaminan perorangan sebagai jaminan utama tanpa penyertaan agunan fixed asset maka tingkat risiko pemberian kredit tersebut sangat tinggi, pada saat nasabah ingkar janji maka proses eksekusi tidak bisa seketika melalui penjualan (lelang) mengingat jaminan perorangan tidak memiliki kedudukan istimewa, eksekusi jaminan perorangan baru dapat dilakukan jika sudah ada putusan pengadilan yang berkekuatan hukum tetap. Penelitian ini akan penulis sajikan dalam bentuk normatif.
