Authors: ÖZTÜRK İrfan , KORKUT Kayıhan Z. 
Published: October 2018

Ekmeklik buğdayda kuraklık verim ve kaliteyi doğrudan etkileyen önemli bir abiyotik stres faktörüdür. Araştırmada bazı ekmeklik buğday genotiplerinin farklı kuraklık seviyelerinde verim ve bazı fizyolojik karakterler arasındaki ilişkiler incelenmiştir. Bölünmüş parseller deneme desenine göre 2008-2009 ve 2009-2010 yıllarında yürütülen ve 15 genotipin materyal olarak kullanıldığı deneme 3 tekrarlamalı olarak kurulmuştur. Denemede ana parsellerde kuraklık uygulamaları, alt parsellerde genotipler yer almıştır. Araştırmada; tane verimi ile üç farklı gelişme döneminde bitki örtüsü sıcaklığı ve bayrak yaprakta klorofil miktarı ölçülmüştür. Ayrıca başaklanma ve olgunlaşma gün sayıları, tane dolum süresi ve mumsuluk oranları ile bu karakterler arasındaki ilişkiler incelenmiştir. Araştırmada genotipler ve uygulamalar arasında önemli farklılıklar tespit edilmiştir. En düşük bitki örtüsü sıcaklığı Kate A-1 de görülürken en yüksek sıcaklık Golia çeşidinde ölçülmüştür. En düşük sıcaklık değerleri gebeleşme (17.21 oC ), başaklanma (19.96 oC ) ve tane dolum dönemlerinde (20.11 oC ) kuraklık uygulanmayan parsellerde ölçülmüştür. En yüksek sıcaklıklar ise başaklanma ve tane dolum dönemlerinde tam kuraklık uygulamalarında belirlenmiştir. Kanopi sıcaklığının tane verimini olumsuz yönde etkilemiş olup kanopi sıcaklığı ile tane verimi arasında korelasyon katsayıları başaklanma öncesi r= -0.779, başaklanma dönemi r= -0.793 ve tane dolum dönemi r= -0.924* olarak belirlenmiştir. Kuraklık stresi klorofil miktarını üç bitki gelişme döneminde de düşürmüş olup en yüksek klorofil miktarı kuraklık stresi uygulanmayan parselde belirlenmiştir. Genotiplerde başaklanma döneminde en yüksek klorofil miktarı ÖVD2/27-07 ve tane dolum döneminde EBVD24-07 hatlarında ölçülmüştür. Tane verimi ile bayrak yaprak klorofil içeriği arasında ilişki başaklanma öncesi r= 0.499, başaklanma dönemi r= 0.498 ve tane dolum dönemi r=0.954* olarak belirlenmiştir. Araştırma sonucu kanopi sıcaklığı ve klorofil kapsamının farklı kuraklık stresi altında verim için seleksiyon kriteri olarak kullanılabileceğini göstermiştir.

Published: October 2018

Bu çalışmada, bağ çubuklarının kesme
işlerinde kullanılabilecek bir makinanın tasarımında temel parametreler olan
kesme kuvveti, kesme gerilmesi ve enerji gereksiniminin belirlenmesi
amaçlanmıştır. Bu amaç doğrultusunda 8 farklı üzüm çeşidi için sürgün çapına ve
neme bağlı olarak kesme özelliklerinin değişimi incelenmiş ve istatiski olarak
değerlendirilmiştir. Deneylerde kullanılan asmaların sürgünleri Diyarbakır
ilindeki şaraplık üzüm üreten üreticilere ait bağlardan temin edilmiştir.
Sürgünlerin kesme özelliklerinin belirlenmesinde, Llyod LRX plus, 5000 N
kapasiteli biyolojik malzeme test cihazı kullanılmıştır. Elde edilen sonuçlara
göre, bitkinin kesme özelliklerinin sürgün kesit alanıyla doğrudan ilişkili
olduğunu gözlenmiştir. Kesilen sürgünlerin çaplarının aynı olsa bile kesme
özellikleri bakımından çeşitler arasında önemli farklılıklar ortaya çıkmıştır.
Çapa bağlı olarak elde edilen maksimum kesilme kuvveti değerleri yabancı üzüm
çeşitlerinde elde edilirken, en düşük değerler ise yerli şaraplık üzüm
çeşitlerinde saptanmıştır. Yabancı çeşitler için elde edilen en yüksek kesme
değerleri ise sırasıyla Cabernet Franc, Shiraz, Cabernet Sauvignon, Chardonnay,
Merlot ve Tannat çeşidinde elde edilmiştir. Araştırma sonuçlarına göre maksimum
kesme kuvveti 2084 N ve kesme enerjisi 662 Ncm olarak % 42 Nem içeriğinde, 10 mm sürgün çapında
Cabernet Franc çeşidinde bulunurken, aynı sürgün çapında en düşük kesme kuvveti
1595 N ve kesme enerjisi 531 Ncm olarak Tannat çeşidinde elde edilmiştir.
Dolaysıyla bir budama veya kesme makinasının tasarımında ve imalatında
çeşitlerin bu kesme özellikleri önemli bir etkiye sahiptir. Bu nedenle, budama
ve benzeri kesme işlerinde kullanılacak bir makina tasarımında mutlaka üzüm
çeşidinin kesme özellikleri dikkate alınmalıdır. Bu da makina imalatçılarının
bir yandan daha modern budama makinalarının imalatının yapılmasına yapmasına
olanak sağlayacaktır.

<p>Setiap orang memerlukan tanah untuk kehidupan mereka karena tanah memiliki fungsi yang begitu strategis. Berdasarkan Undang-Undang Dasar Negara Republik Indonesia Tahun 1945 Pasal 33 ayat 3 yang berbunyi bumi, air dan kekayaan alam yang terkandung di dalamnya dikuasai oleh Negara dan dipergunakan untuk sebesar-besarnya kemakmuran rakyat. Maka masyarakat harus meninggalkan tanahnya sehingga tanah tersebut menjadi terlantar. Ada empat cara untuk penertiban tanah terlantar antara lain inventarisasi tanah hak atau dasar penguasaan atas tanah yang terindikasi terlantar, identifikasi dan penelitian tanah yang terindikasi terlantar, peringatan terhadap pemegang hak dan penetapan tanah terlantar yang didasarkan pada Peraturan Kepala Badan Pertanahan Nasional Republik Indonesia Nomor 4 Tahun 2010 tentang Tata Cara Penertiban Tanah Terlantar kemudian tanah ini dapat dijadikan seperti semula. Sehingga dapat dikatakan bahwa penertiban terhadap tanah terlantar untuk memberikan kesadaran terhadap pemegang hak bahwa penelantaran tanah merupakan tindakan yang tidak berkeadilan, yang dapat menyebabkan hilangnya peluang untuk mewujudnyatakan potensi ekonomi tanah.</p>

The Uniqueness of Family Firms
Authors: Harijono Harijono 
Published: October 2018

This study focuses on family business theory from two theories of the firm perspectives: the incomplete contract and the agency perspectives. It shows that families represent a special class of large shareholders that potentially have a unique incentive structure and power in the firm. The unique characteristics of family firms potentially make their performance and their corporate decisions making different from those of non-family firms. The empirical evidences tend to support this argument. However, further quantitative and qualitative research to establish the relations between family control and several aspects of corporate decision making in different institutional and cultural settings remains to be done.

Published: October 2018

Interactivity, digitality, and virtuality are three important aspects of Internet technology, among others. Thanks to its break-through characteristics, internet brings many changes into the lives of people. Due to its accessible features and loads of information, many people’s needs on information, entertainment and social interaction are necessarily answered. One of the most interesting and widely developed features on internet is online game. Online game promises its users the ability to connect with other fellow users in real time. This paper intends to view online game as a second reality, different with the real world we live in. By employing psychoanalysis theory initiated and developed by Sigmund Freud, this paper sees online game as a playing field for human Id (Freudian biological desire), constantly repressed in real world due to its persisting conflict with ego and super ego. Online game commonly perceived as “unreal virtual sphere” facilitates its users to freely conduct certain actions which, in normal and real life, are forbidden, such as killing and raping. Therefore, online game could be perceived as catharsis, or outlet for bestial desire of human being. The hypotheses needs to be proven in this paper is whether sexual and violent character of online game really possess catharsis function to release the biological desire of the users, or, the other way around, namely, repressing the Id. The methodology used in this paper is case study with both observation as well as literature study relevant with online game in question. The authors attempt to observe directly and also conduct interview with ten children in five different internet shop (warnet). The theoretical paradigm used is twofold, namely, catharsis theory and Freudian psychoanalysis. To support the main paradigm used, the authors also use media dependency theory proposed by DeFleur, including, but not limited to, arousal and aggressive cues.

Published: October 2018

Political system in Indonesia after New Order regime has entered into a new phase, which is both fundamentally and practically different. With the growth of freedom of expression and the rise of information and communication technology (ICT), the use and practices of political communication is also striking a fair balance, two-ways direction, no longer dominated by government-only apparatuses. The use of internet and New Media in political communication realm has been pioneered since 1997, and has been growing ever since, thanks to the new practices of local election (Pilkada). This paper will address firstly, the theoretical framework of political communication in e-Democracy, and secondly, the application of New Media (website, blog, and social media sites) in local-based political communication, namely Pilkada in Banten at October 23, 2011. Having analysed the phenomenon in question, a surprising result appears. Even though all candidates of Governor and Deputy Governor of recent Pilkada Banten have used New Media as their communication and campaign media, nevertheless the interactivity factor embedded within those “New Media use” are largely neglected.
