Authors: Susilowati, S; Laia, S; Purnomo, H Abstract: Spontaneous fermentation of ginger are very popular in China and Japan and the product are known as pickled ginger, in Indonesia its popularity is still limited in certain society, but more increasing with the present of more japanese cuisine restaurants especially in metropolitan cities. Hence a study on the effect of salt concentration and fermentation time on pH value, total acidity number and microbial characteristic of pickled ginger (Zingiber officinale Rosc.) was conducted. Completely Randomized Design was used in this study with two factors namely salt (NaCl) concentrations (2.5, 5.0 and 7.5 % w/w) and fermentation time : 5 and 10 days, and this experiment was replicated three times, while the parameters observed were pH value, total acidity , Lactic Acid Bacteria total counts and characterisation and identification of lactic acid bacteria of selected pickled ginger sample using index de Garmo was carried out by 16SrRNA gene sequencing analysis. The selected sample was the one prepared using 2.5% w/w salt and 5 days fermentation at 26o C with pH value of 3.40, total acidity 0.92% and lactic Acid bacteria total counts of 7.56 x 106 CFU/ml. Based on 16S rRNA gene sequencing analysis and similarity by Neighbor Joining (NJ) method with phylogenic tree construction, the lactic acid bacteria of selected pickled ginger identified were Lactobacillus plantarum strain BM4 and Lactobacillus plantarum LOCK 0991 with similarity of 86% . 2018-12-01T00:00:00Z https://repository.ukwk.ac.id/handle/123456789/1852 Title: LABOR UNION AND THE COMPANY PERFORMANCE: INDUSTRIAL CONFLICT Authors: Ratih, Dewi; Yunus, Achmad Abstract: Today many conflicts arise that lead to destructive conditions concerning industrial relations, including conflict between the workers as a key element of the production and the entrepreneur as the owner of capital. Many workers demands against their rights to entrepreneurs who cannot be packed in containers appropriate mediation so that not infrequently lead to greater conflict. Frame of mind in this study based on the fact that the management of conflicts in industrial relations requires the involvement of all stakeholders in the organization. Support regulations and policies are also strongly demanded that the conflict can be managed properly in order to achieve a favorable climate objective so that employees can work optimally in order to achieve organizational goals through the organization’s culture. Organizational culture is very important role in supporting the creation of an effective organization. There are certain characteristics as forming an organizational culture that is used in this research is focused on the culture of quality. This study aims to map the factors related to conflict management in particular industrial worker organization’s involvement in shaping the culture of the organization in conflict management. This study uses a qualitative research design with a case study approach where the analysis of this research is done inductively. The design of this study refers to the model cycle of Kemmis and M. Taggart (1998) with four stages, namely: 1) preparation, 2) the implementation phase, 3) the stage of monitoring, and 4) the stage of reflection. The role of labor union organizations to be very important in determining management policies. The union becomes a container in delivering the aspirations of employees that are part contribution to the company’s employees. Union organization is able to manage conflict are expected to be part of the motor of the company’s progress. Proven in some respects in accordance with the results of the research, the union was able to resolve conflicts without weakening partly conflicting parties. In running the organization, cultivate union members to work together and form solidarity among its members. Behaviors and habits that is expected to shape the culture of the organization mature and become a strong foundation for the progress of the company. 2016-12-01T00:00:00Z https://repository.ukwk.ac.id/handle/123456789/1850 Title: Equity market timing and capital structure: evidence on post-IPO firms in Indonesia Authors: Ratih, Dewi Abstract: Purpose – The purpose of this paper is to analyze and evaluate the impacts of equity market timing on corporate capital structure policies in Indonesia by apply Baker and Wurgler’s analytical approach to firms in Indonesia to see, first, if that approach applies to Indonesian firms and, second, if it can be generalized to other emerging markets. Design/methodology/approach – This study will focus on capital structure policies based on Market Timing Theory in developing countries, which uses the panel data of companies listed in Indonesian Stock Exchange after IPO. The companies used as research object are 70 firms in the non-financial/non-banking sector with the observation period of 2000–2015. The period of measurement is five years after IPO. Using a past market value in which equity market timing is measured in two-time measurements, i.e. yearly timing and long-term timing to prove its persistence. Findings – Consistent with equity market timing theory, the results suggest that firms tend to issue equities when their market valuations are relatively higher than their book values and their past market values are high. As a consequence, the firms become underleveraged or have their debts reduced in the short run. The results of long-term measurement on equity market timing do not appear to affect the firms’ capital structure decisions due to the firms’ relatively quick adjustments of optimal capital structures. The conclusion is that equity market timing is an important element in the short run but not in the long run. Research limitations/implications – The results of this study describe how firms in Indonesia take advantage of temporary market share fluctuations through equity market timing in their capital structure policies before ultimately making adjustments to the directions they are targeting. Practical implications – The use of equity market timing is more aimed at reducing the debt ratio and avoiding unfavorable conditions in the debt market, as well as taking advantage of the capital gains derived from the differences in their stock prices. This study also has practical implications on investment policies that need to consider the adaptation factor of the industrial environment when it comes to making capital structure decisions, including how the entity must take policy when uncertain economic conditions. Social implications – Through the research behavior of capital structure more in-depth decision is expected to provide an overview for investors widely in determining investment policy. Thus, the investment strategy is more planned and can also anticipate unexpected conditions. Originality/value – This research is the first study to analyze and to evaluate the impacts of equity market timing on corporate capital structure policies on post-IPO firms in Indonesia. This research is an empirical study that investigates the relevance of equity market timing considerations in the determination of debt- equity choices in the capital structure, included in the conditions of the global financial crisis. 2021-01-01T00:00:00Z https://repository.ukwk.ac.id/handle/123456789/1840 Title: Contraction Coefficient (Cc) Characteristic for Flow Under Sluice Gate using Trapezoid Baffle Block and Sill Authors: Sunik Abstract: Laboratory experiment was development to know contraction coefficient (Cc) characteristic for the flow under sluice gate while it operated with variation discharge and open gate using trapezoid baffle block with sill. Prototype model as horizontal channel used sluice gate installed on it made from fiberglass. Dimension of horizontal fiberglass channel: length (L) = 9 m, width (B) = 50 cm; sluice gate dimension, height (h) = 80 cm, thick (t) = 1 cm, width (b) = 50 cm. Variation of discharge (Q) and open gate (a = 1,2,3,4 cm) make the flow rise the contraction coefficient (Cc). Models of baffle block as trapezoid (Bb = 2.8 cm) installed as three row, specified location 25 cm after sluice gate using end sill (code T4-A, 10 running; code T4-B, 10 running; T4-C, 10 running; T4-D, 10 running). The height of flow (h) and velocity (v) were measured during each running test then Froude number and contraction coefficient (Cc) were analyzed. The result showed that trapezoid baffle block model T4-A (28 cm x 28 cm x 28 cm) (Fr = 0.12 - 0.50) gives the better performance modelling of Cc in term of the initial Froude number with R2 = 0.9186, Ls1, Ls2 = 32 mm, L2 = 100 cm. It was concluded that using three rows configuration of trapezoid baffle block with T4-A model gave better model than T4-B, T4-C, T4-D. 2020-06-01T00:00:00Z
