La denominación de origen Penedés: contexto histórico, geográfico y enoturístico
Authors: Molleví Gemma , Miró Albert
Published: January 2019

La Denominación de Origen Penedés, región ubicada entre Barcelona y Tarragona, es la más importante de Cataluña en términos de tamaño y producción. Su historia y patrimonio vitivinícola son muy antiguos y de gran riqueza. Así, este trabajo de investigación se centra en un doble objetivo, por un lado se pretende contrastar la hipótesis de la existencia de un relación positiva entre el número total de empresas viticultoras y la producción total, en hectolitros, y por otro en los últimos años existe un interés común por proteger su paisaje vitícola. Es por ello que se ha elaborado la Carta del Paisaje del Penedés, paisaje vitícola que se quiere postular como bien cultural Patrimonio de la Humanidad por la UNESCO. Bajo estas circunstancias las instituciones públicas y privadas del Penedés pretenden convertir la D.O. Penedés en Denominación de Origen Calificada, asimismo para alcanzar este objetivo se trabaja para promover eficientemente el enoturismo de calidad.

Published: January 2019

Türkiye ekonomisi büyüdükçe enerji ihtiyacı ve ekonominin
petrole olan talebi artmaktadır. Türkiye’de işsizlik oranları ve dünya petrol fiyatları arasındaki
ilişki, 1980-2016 dönemi için; VAR modeli analizi, Johansen eş bütünleşme
testi, Granger nedensellik testi  ve hata
düzeltme modeli ile incelenmiştir. Sonuç olarak ülkemiz için işsizlik oranları  ile petrol fiyatları arasında bir nedensellik
ilişkisinin olduğu ortaya çıkmıştır. Petrol fiyatları her ülkenin ekonomisi için önemli rol
oynamaktadır. Petrol fiyatlarındaki ani artışlar yüksek enflasyon, işsizlik ve
GSMH’nın düşmesine yol açmaktadır Petrol fiyatındaki artışın Türkiye
ekonomisine doğrudan olumsuz etkileri büyüme, ödemeler dengesi, enflasyon ve
bütçe üzerinde olmakla beraber ayrıca işsizlik oranı üzerinde etkisinin olduğu
sonucuna varılmaktadır.  Türkiye’de 1970,
1980 ve 1990’lı yıllarda yaşanan ekonomik krizlerin öncesinde dünya petrol fiyatlarında
ciddi artışlar yaşandığı görülmektedir. Ekonomik krizlerin ardından işsizlik
oranlarında ciddi artışlar meydana gelmiştir. 2040 yılında dünya nüfusunun 9 milyara yaklaşacağı, enerji talebinin
%35 artacağı ve bu talebin %60’ının petrol ve doğalgazdan karşılanacağı
Türkiye’nin de bu talep artışında ilk 10 ülke içerisinde yer alacağı
belirtilmektedir

Örgütlerin
verimliliklerinin sağlanmasında ve varlıklarını devam ettirebilmelerinde işgücü
önemli bir paya sahiptir. Bu öneme binaen çalışanların işe en uygun kişiler
olmaları bu amacın gerçekleşmesinde önemli hale gelmektedir. Çalışanlar işe
uygun kişiler olsalar dahi zamanla kendilerindeki gelişimlerle birlikte daha
nitelikli duruma gelebilmektedirler. Bu durum literatürde aşırı niteliklilik
olarak adlandırılmaktadır. Aşırı niteliklilik algısı ise çalışanların
kendilerinin, yöneticilerinin veya çalışma arkadaşlarının çalışanın
niteliklerini işin gereklerinden fazla olarak algılamaları, çalışanların
gelişim olanaklarının olmadığı yönündeki algısıdır. Bu çalışma ile algılanan
aşırı niteliklilik kavramına kendini nitelikli olarak algılayan kişiler ile
çalışanının aşırı nitelikli olarak algılayan amir açısından bakılmış, kendini
aşırı nitelikli olarak algılayan kişilerin aslında amiri tarafından aşırı

İşletmeler,
geleceğe dönük faaliyetlerini finansal planlama yardımıyla şekillendirir.
Proforma bilanço, finansal yönetim fonksiyonları arasında yer alan finansal
planlamanın önemli uygulamalarından bir tanesidir. Bunun nedeni, proforma
bilanço yardımıyla gelecek dönemdeki kaynak ihtiyacı ya da fazlasının bugünden
belirlenebilmesidir. Bu sayede, işletmeler daha sağlıklı finansal kararlar
alabilirler. Proforma bilançonun, belirli bir tarih itibariyle düzenlenen
klasik bilançodan farkı, geleceğe dönük ve isteğe bağlı olmasıdır. Proforma
bilanço oluşturulurken çeşitli yöntemlerden yararlanılabilir. Bu yöntemler
sırasıyla, kapsamlı bütçeleme yöntemi, satışların yüzdesi yöntemi, oranlar
yöntemi, regresyon yöntemi ve günlük satışlar yöntemi olarak ifade edilebilir.
Bu çalışmada, küçük ölçekli imalat sektöründe yeni kurulan örnek bir firmanın
gelecek dönem proforma bilançosu oranlar yöntemiyle oluşturulmuştur. Bunun
sebebi, söz konusu yöntemin hesaplamadaki kolaylığı ile yeni faaliyete geçen
işletmelere uygulanabilirliği gibi üstünlükleridir. Elde edilen sonuçlara göre,
yeni kurulacak örnek işletmenin gelecek yıl kaynak ihtiyacının bulunduğu
görülmüştür. Kaynak ihtiyacı eklendiğinde, proforma bilançoda aktif ve pasif
eşitliğine ulaşılmaktadır. Kaynak ihtiyacı karşılanırken, finansman politikası
kapsamında, yabancı kaynaklar ya da özkaynaklardan yararlanılabilecektir.

Urban organic waste is a potential source of greenhouse gases. Methane gas is an energy source that can be used as fuel. It is difficult to find land for Landfill alocation in the major cities and often becomes a difficult social problem. Structured Landfill Cell is used to treat the waste at the landfill, with the aim to use land more scalable, easier waste management and control, better sanitation, better water control leachate and gas produced can bemanaged optimally and compost can be utilized with the production and quality control.This new system was first used in Indonesia by PT Navigats Organics Energy Indonesia in landfill Suwung, Denpasar, Bali. There are 5 cells already built in Suwung and two of cells have been filled with garbage. Each cell contains 12,000 m3 soliswaste. Observations carried out on gas productivity of two cells that have been filled, with a dry treatment on cell 1 (dry cell) and a wet treatment in cell 2 (wet cell). The observed gas is CH4, CO2,and O2 as the main parameters, with the addition parameters are CO and H2S. The instrument used is the GA 2000 Plus. Observations of two cells made for 4 months, with the content of CH4 around 40 to 50% in the first month and gradually decreased to reach 18 to 25% in the fourth month. Carbondioxyde going up and down following condition of CH4 and its value ranges between 16 and 28%. Oxygen consentration around 2 to 14%.For keeping engine performance the consentration of methane should more than 28%and O2 content lower than 6%. Cell with watering will temporarily reduce CH4 and CO2 and O2 increase, but it is slowly rising again. Carbonmonoside values tend to increase with age garbage (10 sd 350 ppm), whereas irregular H2S values ranging 0 up to 24 ppm, allegedly associated with the low protein content in the trash. Sewage treatment system is proven to increase CH4 gas, yet still needed modifications of structure and the gas collector pipe system so that productivity can be improved.Key Words : Solidwaste, Metana, Cell System

Nepenthes albomarginata Lobb ex Lindl. is a carnivorous plant, distributes in several regions in Indonesia. The plant population decreases drastically because of over exploitation and ruining nature habitat. Plant propagation by nature and cutting are not enough to rehabilitation its population. In vitro culture of N. albomarginata was carried out using plantlets grown from the seeds in vitro. Plantlets were cut to became two part explants, consisted of shoot tip and under-shoot tip cuttings. These cutting explants were grown on Murashige & Skoog (MS) media with addition of plant growth regulators of 6-benzylaminopurine (BA), combined with or without-naphthalene acetic acid (NAA) or 2,4-dichlorophenoxyacetic acid (2,4-D) at 1 mg/l. Shoot tip cuttings of N. albomarginata formed double multiple shoot 25,00% on control; formed triple multiple shoots 25,00% onBA 1 mg/l treatment; formed callus 37,50%, triple or quartet shoots 25,00% and rooted plantlets 25,00% on BA 1 mg/l + NAA 1 mg/l treatment. The under-shoot tip cuttings ofN. albomarginata formed double – triple shoots 25,00% and rooted plantlets 37,50% on control; formed double – triple shoots 25,00% and rooted plantlets 12,50% on BA 1 mg/ltreatment; formed callus 12,50%, double - pentacle shoots 37,50% and rooted plantlets 25,00% on BA 1 mg/l + NAA 1 mg/l treatment. 2,4-D 1 mg/l or its combined with BA 1mg/l treatment caused deadly shoot tip or under-shoot tip explants. The combination of BA 1 mg/l + NAA 1 mg/l was the best treatment for producing callus, multiple shootsand rooted plantlets of N. albomarginata.

A study to improve the raw water quality at Taman Kota Drinking Water Company was conducted by using pilot plant of biofiltration system. The pilot plant was run by pumpingthe raw water from river to the reactor continuously with various Hydraulic Retention Time. Samples of raw water and treated water were taken daily and analyzed for pH,Total Suspended Solid (TSS), Organic matter, Ammonia nitrogen and Detergent (MBAS). The results showed that performance of biofiltration system decreaed due to shortening Hydraulic Retention Times (HRT). The longer HRT caused bigger volume of biofiltration tank. Therefore, this study suggests that the optimum Hydraulics retention time is 1 hr. In this HRT, the treated water quality were 7.2 for pH, 40 mg/l for TSS, 10,7 mg/l for organic matter, 0.35 mg/l for ammonia nitrogen and 0.1 mg/l for MBAS. These resultscomply with the Regulation No. 582 year 1995 for raw drinking water quality (class B).

The gases produced from Sanitary Landfill are to be monitored and collected so as not to cause environmental pollution. TPA Bangklet in Bangli District, Bali Province iscurrently being reviewed and further developed to be pilot Sanitary Landfill in Indonesia. A system of monitoring and capturing or collecting LFG (Landfill Gas) has been done toBangklet’s Sanitary Landfill of the dry Cell Pilot Plant, especially for the second layer. LFG measurement results show the average value of 32.99% for CH4, 31.87% for CO2, 5.4% for O2 and up to 29.68% for other gases. But the arrests and the collection of LFG system still needs improvement, because there are some leaks that led to the entry of oxygen into the system and vice versa the LFG is released into the atmosphere. It is suggested that the pattern of capture, and utilization of LFG monitoring system have to be applied to all Sanitary Landfills located in Indonesia.

Aliran permukaan/limpasan (run off) merupakan salah satu variabel hidrologi yang sangat penting di dalam menunjang kegiatan pengembangan sumber daya air. Metode prediksi yang handal untuk menghitung jumlah dan laju limpasan yang berasal dari permukaan tanah dan bergerak menuju sungai di suatu DAS yang tidak dilengkapi alat ukur (ungaged watershed) adalah suatu pekerjaan yang sangat sulit dan memerlukanwaktu yang banyak. Penelitian ini dilakukan di DAS Ciliwung Hulu, yang merupakan daerah penting dalam kotribusi banjir di Jakarta. Untuk mengetahaui run off  yang terjadi, digunakan data curah hujan dan debit Tahun 2007-2009. Sebagai model, untuk mengetahui run off menggunakan peta penggunaan lahan, peta jenis tanah, dan topografi. Peta-peta tersebut diolah dengan menggunakan Arcview, sehingga didapatkannilai CN. Berdasarkan analisis perhitungan, besarnya debit mendekati 50% dari tebal hujan. Kondisi ini mengindikasikan bahwa kondisi DAS Ciliwung Hulu sudah tidak mampu lagi menyerap curah hujan dengan baik. Korelasi antara hasil prediksi run off model yang menggunakan CN dengan perhitungan run off observasi cukup baik. Hal ini menunjukkan bahwa metode Curve Number cukup dapat mepresentaskan hubungancurah hujan dengan aliran permukaan (run off). kata kunci : Run off observasi, run off model, curve number AbstractRun off (surface flow) is one of the most important hydrological variable in supporting the activities of water resources development. A reliable prediction method to calculate the amount and rate of runoff from the land surface caused by the rain that falls in a watershed that is not equipped with measuring devices (un gauge watershed) is a verydifficult job and requires a lot of time. The research was conducted in the watershed Ciliwung Hulu, which is an important area in relation to the incidence of flooding in Jakarta. Curve Number (CN) method can be used to predict the amount of runoff from a watershed. This model required input of rainfall; land cover maps; soil type maps,and topography. The maps are processed using Arc View software, so we get the value of CN. In this study, we used of rainfall and discharge data 2007-2009. Based on the analysis of calculation, known that amount of surface flow approaching 50% of rainfall depth. This condition indicates that the Ciliwung Hulu watershed conditions were not ableand proper to absorb of rainfall. The correlation between the results of run-off prediction models using CN with run-off observation was quite good. This indicated that the Curve Number method could be able to represent the relationship of rainfall with surface flow (run off) and also to predict runoff key words: Run off observation, run-off model, curve number

Published: January 2019

Penurunan kualitas dan produktivitas sumberdaya lahan pertanian terutama disebabkan oleh kandungan C-organik yang rendah dan pemupukan yang tidak diimbangi dengan pupuk organik. Cara mengatasinya adalah mengembalikan bahan organik ke lahan pertanian melalui penggunaan pupuk kompos atau pupuk organik granul (POG) berbahan baku kompos. Pupuk kompos sebaiknya dibuat dari seluruh potensi bahan organik yang ada. Timbulan sampah kota yang besar dengan prosentase bahan organik yang tinggi, memiliki karakteristik yang cocok untuk dijadikan pupuk kompos berkualitas baik, dalam rangka memenuhi kebutuhan pupuk organik. Pupuk komposmemiliki kemampuan untuk memperbaiki dan meningkatkan sifat fisik, biologi dan kimia tanah. Keberhasilan program penggunaan pupuk kompos atau pupuk organic yang lain sangat bergantung kepada dukungan stakeholders terkait, serta kepercayaan petani untuk menggunakan pupuk organik. Dengan ketersedian pupuk organik yang berkualitas, yang diberikan secara berimbang bersama pupuk kimia, maka kualitas dan produksivitas sumberdaya lahan pertanian dapat ditingkatkan sehingga dapat mendukung dan memperkuat kemandirian pangan. Kata Kunci: Sumberdaya lahan pertanian, pupuk organik, sampah kota, kompos, kemandirian pangan. AbstractThe quality and productivity degrade of agricultural land resources mainly due to the low level of C-organic content and the fertilizing that do not use organic fertilizers. The way to solve it is by restoring the organic matter to agricultural land through the use of compost or organic fertilizer granules made from compost. Compost should be made from all organic materials that have potential. The high level of municipal solid waste generation with a high percentage of organic matter, contain the characteristics that are suitable to made a good quality compost, in order to meet the needs of organic fertilizer. Compost has the ability to improve and enhance the physical, biological and chemical soil properties. The successful of compost or other organic fertilizer utilization program is mainly depend on the stakeholders support, as well as the confidence of farmers to use organic fertilizer. With the availability of good quality of organic fertilizer, which is given in a balanced way with chemical fertilizers, the quality and productivity of agricultural land resources can be improved to support and strengthen the food self-sufficiency.Key words: Agricultural land resource, organic fertilizer, municipal solid waste, compost, food self sufficiency.
