Abstract

While the need for water supply infrastructure development keeps increasing, many local governments of Indonesia are facing problems related to limited funding. This condition opens up an opportunity for private sector to invest in water supply infrastructure projects through Public Private Partnership (PPP) scheme. As this scheme is relatively new for many local governments in Indonesia, its complexity and typically long duration of the concession period may raise concerns of potential risks throughout the project life cycle. It is, therefore, very important for public sector as owner of the project to understand and to be able to manage risks properly throughout the concession period. The aim of this research is to evaluate risk management of West Semarang Water Supply PPP Project as perceived by public sector. The objectives are to identify, to analyze, and to allocate risks to the right parties. Qualitative and quantitative approaches have been used for the research method. Data were collected through focus group discussion involving 16 relevant officials of local government of Semarang, including its Regional Water Supply Company (PDAM). This research has identified a total of 66 risks as perceived by the public sector, which are then classified into 11 categories, e.g. political, operation, revenue, etc. The proportions of the level of risks are relatively balanced, as follows; low (37.88%), moderate (28.79%) and high (33.33%). In terms of risk allocation, 46.97% of risks are allocated to the public sector, while 37.88% and 15.15% of the risks are allocated to the private sector and shared by both parties, respectively. The results of this research are valuable for the local government of Semarang and can be used as a guidance in managing risks of the PPP project throughout the concession period.

Abstract

The Main Inspectorate (Itama) as internal auditor of BPK RI is obliged to protect the credibility and the honor of its institution. The opinion of financial statements is one of the BPK RI's products that become popular because of frequent bribery cases related to it. Typically, the bribe was given to change the opinion of the financial statements from an examined entity. The anomaly detection method becomes one of the alternative methods for filtering out reports with "problem" opinions to be examined more deeply by Itama. KNN, SVM-RBF Kernel, and J48 method were used for the classification of 150 data of local government financial statements. The validation used in this paper was 60% hold-out validation (60% data for test data and the rest for training data). This paper showed that the KNN classifier (AUC=61.11%) was superior compared to another classifier, but still classified as "poor classification"

Abstract

Sebagai tindak lanjut atas penutupan Dolly, Pemerintah Kota Surabaya telah memberikan kompensasi 5,05 juta rupiah kepada setiap warga yang terkena dampak penutupan lokalisasi. Uang tersebut diberikan dalam bentuk tabungan, sebagian untuk modal usaha dan sebagian untuk bekal hidup sementara hingga penerima santunan bisa bekerja lagi. Selain bantuan berupa dana, bantuan berupa pelatihan keterampilan seperti membuat kue kering, telor asin, deterjen atau sabun cair juga dilakukan. Pendampingan dari mulai pelatihan hingga pemasaran produk sudah dilakukan. Setahun setelah Dolly ditutup, memang beberapa warga mulai beralih ke usaha baru hasil pelatihan, seperti berdagang telur asin atau membuat sabun deterjen yang dijual ke binatu. Pemerintah Kota Surabaya berusaha menjadikan Dolly dan warganya sebagai wilayah usaha ekonomi produktif.Surabaya sejak awal tahun 2016 sedang berusaha mensosialisasikan bahaya dan kerugian menggunakan kresek plastik untuk berbelanja. Bukti partisipasi ini adalah dikenakannya biaya untuk penggunaan kantong plastik atau mengganti penggunaan kantong dengan kardus bekas di banyak minimarket dan supermarket di Surabaya. Hal tersebut mengharuskan para pelanggan membawa sendiri kantong belanja dari rumah, dengan tujuan mengurangi angka penggunaan kantong plastik di Surabaya. Fenomena tersebut membuat peluang tersendiri bagi industri tas sablon untuk berkembang, karena permintaan akan tas yang bisa digunakan lagi (reusable bags) akan semakin meningkat. Peningkatan keterampilan masyarakat untuk mendorong kemandirian merupakan bagian penting dalam rangka mengurangi pengangguran dan kemiskinan terutama di Dolly. Jenis pelatihan yang dilakukan berupa latihan desain, sablon dan jahit tas belanja berbagai macam bahan, selain untuk suvenir juga dapat digunakan sebagai pengganti tas plastik untuk berbelanja dengan desain yang beraneka rupa dan mengangkat beragam tema.

Abstract

Although the utilization of high-strength concrete and high-strength steel can reduced column dimension at high-rise building, the column aspect ratio remain low. These column were tended to dominate by shear failure than flexure failure. The research discusses the numerical analysis of shear critical of High-strength reinforced concrete columns. The Uniaxial Shear Flexure Method (USFM) was used to observe this behavior and examined on the test result. This study showed that USFM method provided conservative prediction. Some modification was proposed in order to improve this method when estimate the shear behaviour of high-strength reinforced concrete column.
