PENGARUH BUDAYA ORGANISASI, KOMPENSASI DAN KEPEMIMPINAN TERHADAP KINERJA KARYAWAN DIMEDIASI MOTIVASI DAN KEPUASAN KERJA (Studi Empiris Pada PT. Bosowa Berlian Motor Cabang Sulawesi Selatan)

This study aimed to analyze the effect of organizational culture, compensation, leadership, work motivation and job satisfaction on employee performance. This also tested the variables through the mediation of work motivation and job satisfaction of employees in PT. Bosowa Berlian Motor Branch, South Sulawesi. This applied quantitative approach of which data was collected using survey methods with questionnaires instrument. The data involved 162 employees as samples that were obtained through purposive sampling. Moreover, the data was analysized with Structural Equation Model (SEM) analysis. As the results, this study indicated that organizational culture, compensation, leadership, work motivation and job satisfaction had a positive and significant effect on employee performance. Organizational culture, compensation and leadership had a positive and significant effect on employee performance through work motivation. While the organizational culture, compensation and leadership had a positive and not significant effect on employee performance through job satisfaction, but directly affected employee performance. Furthermore, the practical implications of this study acknowleged employees in regard withits organizational culture, compensation, leadership, work motivation and job satisfaction on the performance of employees in PT. Bosowa Berlian Motor. The study was limited only branches in Makassar, Maros, Gowa, Pare-Pare, Mamuju, Palopo, Soppeng, Bone and Bulukumba. Instead, this study recommended further research to explore the entire branches of PT. Bosowa Berlian Motor in South Sulawesi in order to generalize more valuable research findings.

Impact and Policy Responses To Oil Price Shock in The SEACEN Countries

In the last five years, oil prices have escalated with prices reaching their highest level of $77 per barrel in August 2006, or relatively the same level as the second oil price shock at the end of the 1970s. Even though the increasing oil price is significant, the impact on the economy as a whole is not the same as in the earlier oil shock. Whereas the previous oil price shocks had caused a severe economic slowdown in almost all countries, the current oil price shock coincides with the one of most favourable global economy in the past 35 years. The muted impact of oil price shock in the recent times is in part related to the different causes and nature of the shock. While shocks in the 1970s and 1980s were caused mainly by sizeable disruptions to oil supply, the recent oil price shock is caused by both the distortions in the supply side and the rapid increase in demand. To a large extent, the current oil price shock has been driven by unexpectedly buoyant demand for oil, particularly in the US, and by the rapidly growing emerging market countries, especially China which has almost doubled its demand for oil in the past 10 years. In contrast with increase in oil demand, world oil production has stagnated. This unbalanced supply and demand is worsened by lower oil inventories in industrial countries and by transportation bottlenecks both for crude and refined oil products that have increased the pressure on oil tanker rates. Taking into account the increasing world oil demand and geopolitical concerns over the security of future oil supplies, the high oil price is perceived to be persistent in the intermediate future. Similarly, the impact of the recent oil price shock has not been very significant in the SEACEN countries as well. Some of countries such as Korea and Taiwan experienced only a limited disruption during and after the shock. Other countries such as Malaysia and Papua New Guinea benefited as government revenue increased and further improved their economies. One plausible explanation for the limited impact of the oil price shock in Korea and Taiwan is that their economic structures have evolved and are now much less dependent on oil than they were in the 1970s. The decreasing oil dependency in some SEACEN countries to some extent is a result of energy policies enforced by governments in the respective countries and has significantly reduced the impact of the oil price shock to the economy. However, empirical results show that subsidy policies in oil price cannot absorb the impact continually. In some countries such as Indonesia and Thailand, the prolonged higher oil price has increased the subsidy burden on the government budget. With regard monetary policy, empirical results show that in some SEACEN countries, monetary policy indicators to some extent are endogenous to oil price hikes. However, such a response only generates a small portion of the output movement due to oil price shocks. An aggressive monetary policy response to an oil price hike would not have succeeded in averting the downturn of the economy. Considering the limited role of monetary policy to economic growth, in anticipation of oil price shocks, monetary authorities would do better to focus their policies on the second round effect rather than on the first round effect of the oil shock. Since domestic oil prices in most countries are determined directly by the international oil price market, the first round effect of such an oil price hike on inflation are likely to be small. However, the second round effect of that oil price hike could be higher and therefore should be estimated appropriately.

EFEKTIVITAS INSTRUMEN HUKUM DALAM ELECTRICITY DIRECTIVE 72/2009/EC

In order to achieve effective competition needs several instruments that are expected to facilitate the achievement of these goals. Electricity Directive[1] provides a new system and some renewal of existing systems. The application of such instruments shall fulfill the fundamental principles. The question may arises, how far these instruments are able to ensure effective competition and its application synergy between instruments. This paper will seeks to addresses the question of by which instruments of the Electricity Directive does the EU ensure competition in the electricity sector, in order to analyses whether all the instruments are sufficient to ensure effective competition this paper also will discusses the benefits and deficits of those instruments. In the first part of this paper general information about the essential idea behind Electricity Directive, the main instruments with their benefits and deficits will be discussed in the following parts respectively. The conclusion part answers the question whether all the instruments are sufficient to ensure effective competition or not. &nbsp

Uji Efektivitas Ekstrak Buah Bintaro (Cerbera Manghas L.) Terhadap Mortalitas Ulat Grayak (Spodoptera Litura F) Secara In-Vitro

Penelitian ini bertujuan untuk menegetahui efikasi ekstrak buah bintaro terhadap tingkat mortalitas larva ulat grayak (Spodoptera litura F) secara in-vitro dan konsentrasi yang tepat meningkatkan mortalitas larva ulat grayak (Spodoptera litura F) secara in-vitro. Rancangan yang digunakan dalam penelitian ini adalah Rancangan Acak Lengkap (RAL), terdiri dari 5 perlakuan, yaitu: B0 = Kontrol, B1 = Ekstrak buah bintaro 30% (30 ml ekstrak buah bintaro + 70 ml air), B2 = Ekstrak buah bintaro 50% (50 ml ekstrak buah bintaro + 50 ml air), B3 = Ekstrak buah bintaro 70% (70 ml ekstrak buah bintaro + 30 ml air), B4 = Ekstrak buah bintaro 90% (90 ml ekstrak buah bintaro + 10 ml air) dan diulang sebanyak 5 kali, sehingga diperoleh 25 satuan percobaan. Masing-masing satuan percobaan menggunakan 10 larva ulat grayak (Spodoptera litura F) dengan instar III, sehingga &nbsp;terdapat 250 ekor larva ulat grayak (Spodoptera litura F) yang digunakan untuk percobaan. Hasil penelitian menunjukkan bahwa insektisida nabati ekstrak buah bintaro pada perlakuan B4 (90 ml ekstrak buah bintaro + 10 ml air) dengan presentase mortalitas sebesar 56% dan memiliki daya bunuh (efikasi) terbaik dengan presentase 56% diikuti oleh perlakuan B3 (70 ml ekstrak buah bintaro + 30 ml air) dengan presentasi sebesar 52%
