Construction Services Law is a statutory regulation that is used to regulate all matters involving construction services, whereas in this study conducted in Jakarta, Indonesia, Law No. 18 of 1999 about Construction Services and Law No. 2 of 2017 about Construction Services. With changes in the Construction Services Law, there are differences in the form of revisions, additions, and reductions. These differences and changes are analyzed with the aim of developing a better Construction Services Law in the future. The method used in this research is a literature study method and questionnaire survey method. Questionnaire questions were formed based on literature studies from previous research and Construction Services Law discussed in this study. Data obtained from respondents were entered into the IBM SPSS Statistics 23 program and then conducted a validity test, reliability test, correlation test, and regression analysis. The analysis shows that there are several Construction Services Lawâ€™s regulations which cannot be a good guide for construction service providers and users yet, due to: the provisions regarding building failures are not well explained, the general lack of provisions governing the selection of expert assessors, the lack of clarity governing labor standards construction work and unclear regulations regarding sanctions for parties involved in construction work.

ABSTRACTChange orders include a number of variants in the scope of work namely the amount of material, design errors, and price changes. This paper discusses change orders in a road construction project in Banten by investigating the causes, studying their effects on the project, and identifying the beneficiaries. The study used five road projects as actual case studies and the questionnaire used a six-point Likert Scale. To determine the ranking of factors that influence the causes of change orders, the effect of change orders and the factors that benefit from change orders are used the Relative Importance Index (RII) calculation. The most important effects of change orders on projects are found to be schedule delays, cost overruns and disputes. The contractor as the party that benefits the most from the change order is followed by the consultant and then the owner. Keywords: change order; road project; Relative Importance Index (RII) ABSTRAK Change order mencakup sejumlah varian dalam ruang lingkup pekerjaan yakni jumlah material, kesalahan desain, dan perubahan harga. Makalah ini membahas change order dalam proyek konstruksi jalan di Banten dengan menyelidiki penyebab, mempelajari efeknya pada proyek, dan mengidentifikasi pihak-pihak yang diuntungkan. Penelitian menggunakan lima proyek jalan sebagai studi kasus aktual dan Kuisoner menggunakan Skala Likert Enam poin. Untuk mengetahui peringkat faktor yang mempengaruhi penyebab change order, efek change order dan faktor yang diuntungkan dari change order digunakan perhitungan Relative Importance Index (RII). Efek terpenting dari change order pada proyek ditemukan adalah penundaan jadwal, pembengkakan biaya dan perselisihan. Kontraktor selaku pihak yang paling diuntungkan dari change order diikuti oleh konsultan dan kemudian owner.

A Change Order is a written and legal work order that changes the scope of the original contract, with compensation that has been agreed upon by the owner and the contractor. Changes can be in the form of adding or reducing the scope of work, changing materials, or changing schedules. Change Order causes the cost of contract items to swell, planning errors and negligence as well as changes in scope that can be reduced by sharpening planning results. The scope of research on road construction in Indonesia, especially in DKI Jakarta and Banten provinces. This study aims to determine the identification of change orders in road construction projects. Data obtained from real data on road construction projects from 2013-2018 on 16 road construction project packages in the form of road construction project addendum contracts. Based on the addendum contract, added work, less work, addition of new items and removal of work items are determined. The identification of change order risk is seen from three aspects, namely the addition and reduction of work items, the removal of items and the addition of new items and the wishes of the owner, thereby increasing the cost of the change order contract. This study found 732 changes in construction work items. Risk identification is obtained from the frequency of changes above 35% which is an intermediate frequency that tends to increase the occurrence of change orders. The results of risk identification were obtained for 31 construction work items, the highest percentage was for Thermoplastic Road Marking work, followed by 30 other construction work items. Keywords: risk identification; change orders; road construction projects AbstrakChange Order adalah perintah kerja tertulis dan sah yang mengubah lingkup kontrak semula, dengan kompensasi yang sudah disetujui oleh pemilik dan kontraktor. Perubahan dapat berupa penambahan atau pengurangan lingkup pekerjaan, perubahan material, atau perubahan jadwal. Change Order menyebabkan biaya item kontrak membengkak, kesalahan perencanaan dan kelalaian serta perubahan ruang lingkup yang dapat dikurangi dengan mempertajam hasil perencanaan.. Lingkup penelitian pada konstruksi jalan di Indonesia khususnya provinsi DKI Jakarta dan Banten. Penelitian bertujuan untuk mengetahui identifikasi change order proyek konstruksi jalan. Data didapat dari data riil proyek konstruksi jalan dari tahun 2013- 2018 pada 16 paket proyek konstruksi jalan berupa kontrak addendum proyek konstruksi jalan. Berdasarkan kontrak addendum maka ditentukan pekerjaan tambah, pekerjaan kurang, penambahan item baru dan penghilangan item pekerjaan. Identifikasi risiko change order dilihat dari tiga aspek yakni penambahan dan pengurangan item pekerjaan, penghilangan item dan penambahan item baru dan keinginan dari pihak owner sehingga meningkatkan biaya kontrak change order. Penelitian ini mendapatkan 732 perubahan item pekerjaan konstruksi. Identifikasi risiko didapat dari frekuensi perubahan diatas 35% yang merupakan frekuensi menengah yang cenderung meningkatkan terjadinya change order. Hasil identifikasi risiko didapat pada 31 item pekerjaan konstruksi, yang tertinggi persentase pada pekerjaan Marka Jalan Termoplastik, diikuti 30 item pekerjaan konstruksi lainnya.
