The Abstract The research aims to determine the role of debt variable, corporate size and growth to the high financial performance of a company with the basis of signaling hypothesis.  Analysis method used is multiple linear regression. The unit of analysis is automotive companies listed on Indonesia Stock Exchange period of 2012-2016. The results of the classical assumption test indicate that this research is free of multicollinear, heteroscedasticity and autocorrelation. The results indicate that debt results in negative direction and not significant, corporate size has a negative direction and not significant and company growth has a negative direction and significant. The three results are not in accordance with the hypothesis proposed in the study.  The present research has limitation that variables  used can only explain 14.4% and the rest are explained by other variables beyond this study.

The supergiant Grasberg porphyry deposit in Papua, Indonesia (5.26 Gt @ 0.61% Cu and 0.57 g/t Au, with no cutoff applied) is hosted by the Grasberg Igneous Complex that fills an upward-flared diatreme ~1,800 m wide at the 4,250-m surface elevation. The Grasberg Igneous Complex is emplaced into folded and strike-slip faulted Tertiary and older sediments and comprises 3.6 to 3.3 Ma Dalam monzodiorite intrusions and subordinate volcanic rocks occupying much of the pipe, the central 3.2 Ma Main Grasberg intrusion, and the NW-SE-trending 3.2 to 3.0 Ma Kali dikes. The Grasberg Igneous Complex contains two porphyry systems: Gajah Tidur copper-(molybdenum) and Main Grasberg copper-gold. The Gajah Tidur intrusion belongs to the Dalam igneous group and is a 3.4 Ma porphyritic monzonite with its top at a 2,750-m elevation; it is overprinted by an extensive, domal, quartz stockwork, with a low-grade and intensely phyllic-altered core, surrounded by molybdenite-bearing veins, with a pre-Main Grasberg Re-Os age, as well as chalcopyrite and overprinting pyrite-covellite veins. The strongly potassic-altered, Main Grasberg monzodiorite porphyry extends from surface to the 2,700-m elevation and is overprinted by a cylindrical, ~1-km-diameter, intense quartz-magnetite stockwork cut by abundant chalcopyrite-bornite veins with rare molybdenite dated at 3.09 Ma. A 700-m-wide annulus of chalcopyrite overprinted by pyrite-covellite-mineralized phyllic alteration surrounds the stockwork. Altered and mineralized Main Grasberg and surrounding Dalam rocks were subsequently wedged apart by the largely unmineralized Kali dikes. Gold is predominantly associated with the Main Grasberg porphyry system where it occurs as 1- to 150-µm (avg ~15 µm) native gold inclusions within chalcopyrite and bornite. Melt and fluid inclusions from Main Grasberg stockwork quartz veins, which exhibit crack-seal textures, comprise K-feldspar-rich silicate melt, sulfide melt, virtually water-free salt melt, and coexisting hypersaline and vapor-rich fluids. Factors important in forming the Grasberg deposit include the following: (1) generation of highly oxidized fertile magma in a postsubduction tectonic setting; (2) efficient extraction of metals from the parental magma chamber; (3) prolonged maintenance of a fluid-accumulating cupola in a strike-slip structural setting that delivered multiple overlapping discharges of metal-rich fluid; (4) highly focused fluid flow into a narrow, permeable stockwork zone in which a steep temperature gradient enabled highly efficient copper and gold precipitation and led to high ore grades; (5) limited dilution by postmineral intrusions; (6) the youthfulness of the deposit minimized erosion and resulted in preservation of nearly all the high-grade Main Grasberg porphyry orebody; and (7) the proximity of the two porphyry centers enables them to be mined as a single, large deposit. The Gajah Tidur copper-(molybdenum) and Main Grasberg copper-gold porphyry centers overlap in space and formed within ~250,000 years of one another. However, their distinct metal endowment, depth of emplacement, and geometry indicate that they formed under different magmatic, hydrothermal, and structural conditions, which are the subject of ongoing research.

The existing cultivation pattern of chilli pepper in Riau Islands is unable to fulfilled all market demands. Dissemination of double production (Produksi Lipat Ganda or Proliga) technology was an effort to increase chilli pepper production in Riau Islands. This study aims to analyze the efficiency of chilli pepper farming with Proliga technology application. This research was conducted in Mei 2019 until April 2020 at Maju Mandiri Farmer Group, Setokok Village, Bulang District, Batam City. The primary data obtained from interviews, and the secondary data obtained from related agencies. Data analysis was carried out by calculating costs, revenues, income, and farming efficiency. Based on analysis results, it can be concluded that chilli pepper farming with Proliga technology generates an income of IDR 699,000,000, and the cost incurred in one planting season (12 months) reached IDR 213,193,500. Therefore, the income obtained by farmers is IDR 485,806,500 / hectare. This chilli pepper farming is considered efficient and profitable for farmers, as indicated by the R/C ratio value of 3.27.

The research context with the theme of the social construction of repong damar culture has been carried out in various fields of science. The research was also conducted in a variety of different perspectives and focus to produce different findings and theorizations. This research is considered important because it is in line with the current shift in the local culture that is currently happening a lot. In many ways, local culture is often positioned opposite the thinking of the younger generation who consider it outdated. This research was motivated by the repong damar culture that existed in Lampung’s Saibatin community, Pesisir Barat District, Lampung. Resin cultivation in Lampung society Saibatin has become a hereditary practice and lasts for generations. The practice of resin which has been around for a long time eventually became a habit that was very attached to the Saibatin Lampung community. The purpose of this study was to find out how the damar cultivation practices can be formed and what kind of social construction then made the practice of resin cultivation to survive today. This study uses a qualitative method with an ethnographic approach. Also, this study also uses the theory of Social Construction from Peter L. Berger. Data collection techniques used in this study were interviews, observation, and documentation. The results of the study on the Social Construction of Repong Damar in Saibatin Lampung Community, Pesisir Barat District, Lampung showed that the practice of damar cultivation was formed around the beginning of the 1827s, which began with two main factors, namely after crop failure from cloves and pepper on the West Coast. Furthermore, the trigger for the emergence of this practice was also due to the actions of a trader who initially traded to Singapore while looking at market commodities that had high economic value. Upon returning the merchant to the West Coast, he recounted that gum resin had a high economic value which was sought after by traders from other countries as materials for making paints, cosmetics, and lighting. The Saibatin Lampung community then used the information and manifested the actions taken by traders by conducting large-scale resin cultivation. Subsequent developments, from the past until now several aspects make the practice of resin can continue to survive, including the existence of a process of habituation, legitimacy, and the process of socialization to the family and the environment.
