Abstract

The capital market is a place for companies to seek funds to finance their business activities. In addition, the capital market is also an effort to collect public funds directly by investing funds in healthy and well-managed companies. The main function of the capital market is as a means of capital formation and accumulation of funds for financing a company/issuer. The presence of capital market institutions in Indonesia adds a row of alternatives for people who have excess funds and are interested in investing to invest their funds This paper attempts to explain how the development of investment in the capital market, besides that this paper tries to describe some of the risks that have the potential to occur in investing in the capital market.

Abstract

Buildings are the physical form of the results of construction work that are integrated with their place of domicile, partly or wholly located on and/or in the land and/or water which functions as a place for humans to carry out their activities, both for housing (residence), religious activities, business activities, social activities, culture, and special activities (Article 1 Number 1 Law Number 28 of 2002 Concerning Building Buildings). The success or failure of a construction project is influenced by three aspects, namely costs that do not exceed the budget, quality according to specifications and time according to the implementation schedule. The existence of project time scheduling is needed to complete the project in a timely manner using several methods. This study aims to create a network for building construction projects using the Critical Path Method (CPM) and identify any work activities from building construction projects that are on a critical path. Research data only consists of secondary data in the form of project time schedules and documentation photos. Based on the analysis, it is known that there are 11 types of work that are on the critical path network of the Abdul Manap Hospital Inpatient Building Development Project in Jambi City using CPM analysis, which consists of AA (Preparatory Work) – BA (Work on Structure 1st Floor) – BB (Work on Structure 2nd Floor) – BC (Work on Structure on 3rd Floor) – BD (Work on Structure on 4th Floor) – BE (Work on Structure on Floor 1) – DF (Installation of Dirty Water, Used Water & Vent) – DA (Work on Structures on 4th Floor) Air Conditioning work) – DO (Lightning Protection Work) – FF (Chopstick Work) – FG (Parking and Greening Work). The total duration/time of completion of all work on the critical path is 240 days.

Abstract

Kota Pekanbaru dihubungkan melalui jalan menuju Kota Dumai, di Propinsi Riau yangmerupakan ruas jalur penting di Sumatera, dengan kondisi jalan 2 lajur 2 arah yang diprediksi akanmengalami overcapacity pada tahun 2015. Untuk memperlancar transportasi antara kedua kotatersebut maka direncanakanlah pembangunan jalan tol. Untuk itu perlu dilakukan identifikasirisiko pembangunan jalan tol ini sebagai salah satu bagian dari analisis kelayakannya. Penelitianini bertujuan mengidentifikasi dan mengukur besaran probabilitas risiko dan dampak risikopembangunan jalan tol ini pada tahap pra-konstruksinya. Analisis risiko yang mungkin terjadi jugadikuantifikasi dalam bentuk probabilitas dengan melakukan simulasi menggunakan software@Risk Project. Diidentifikasi 5 faktor utama risiko pada proyek ini yaitu: risiko perizinan, studikelayakan, desain, pembebasan lahan dan investasi. Besar probabilitas risiko yang diukur padaproyek jalan tol pada tahap pra konstruksi ini lebih kecil dibandingkan parameter yang dikeluarkanoleh Puslitbang PU. Hal ini disebabkan kondisi masyarakat Riau yang relatif lebih kondusif dalampembangunannya. Dari hasil simulasi diperoleh nilai rata-rata (mean value) pembangunan proyekini adalah Rp. 819,65 Milyar dengan rentang nilai rencana anggaran pembiayaan dari Rp. 783,07Milyar sampai Rp. 847,10 Milyar. Dampak risiko terhadap kenaikan rencana anggaran biayainvestasi sebesar 12,37% (Rp 102,24 Milyar) dengan faktor risiko sebesar 0.590 maka tergolongberisiko sedang. Risiko yang paling sensitif adalah (i) Ketersediaan lahan, (ii) Proses ganti rugi,(iii) Penolakan Masyarakat, (iv) Banyaknya calo tanah, dan (v) sumber pendanaan yang belumjelas. Maka mitigasi resiko dapat difokuskan pada lima parameter diatas.

Abstract

The need for electrical energy is changing and increasing, requiring system flexibility always to be changed and developed. On the other hand, changes in the configuration of the electric power system due to the addition of components or sub-systems also change system parameters such as impedance or level of fault current (short circuit current). This paper presents a study of changes in the fault current caused by adding a new generating bus to an electric power system. This paper aims to determine the change in short-circuit current due to the addition of generators on new buses connected to existing buses to identify the most suitable location for adding these generators based on short-circuit current levels. Three-phase short circuit faults are simulated and analyzed on the IEEE 14 bus standard system using ETAP software with a base MVA 615 MVA. The addition of generators was carried out at five locations with varying generating capacities. The research results show that the short circuit current will change significantly when adding a generator bus to bus 13, with an average percentage change of 5,656%. The smallest change occurs when adding a generator to bus 2, with an average percentage change of 2,417%. The research results conclude that connecting a generator to a new bus linked to an existing generator bus (PV bus) is more effective than connecting it to a new bus associated with a load bus (PQ bus).
