Published: December 2018

Kesatuan Pengelolaan Hutan Produksi (KPHP) Awota terbentuk setelah melalui tahapan berdasarkan pedoman pembangunan KPH, yaitu dari pencadangan awal hingga ditetapkan sebagai satu kawasan KPHP oleh Pemerintah Pusat. KPHP Awota telah menjalankan tugas dan fungsi untuk menyelenggaraan Tata Hutan dan Penyusunan Rencana Pengelolaan Hutan serta Pemanfaatan Hutan. Namun, keberhasilan pengelolaannya tidak terlepas dari berbagai dinamika dan persoalan, seperti masih terdapat konflik antara masyarakat dan pemerintah, belum selesainya proses rekonstruksi tata batas, dan belum  adanya jaminan keamanan terhadap investasi berbagai pihak di wilayah KPHP tersebut. Tujuan penelitian ini adalah  untuk menilai kinerja KPHP Awota dalam pelaksanaan pengelolaan hutan di tingkat tapak dengan menggunakan kriteria dan indikator dari Forest Watch Indonesia versi 1.0. Hasil penilaian kinerja menunjukkan bahwa nilai indeks kinerja pembangunan KPHP Awota pada tingkatan sedang dengan nilai 2,13 yang berarti bahwa KPHP Awota sudah cukup siap dalam mewujudkan fungsinya sebagai pengelola di tingkat tapak. Beberapa kriteria perlu menjadi perhatian, yaitu kemantapan kawasan, rencana kelola, mekanisme investasi, dan pelaksanaan pengelolaan dalam lingkup KPH sehingga harus diperkuat untuk menjamin operasionalisasi KPHP di tingkat tapak.

Aims

Stent implantation in ST-segment elevation myocardial infarction (STEMI) patients can be challenging and sometimes associated with immediate and long-term suboptimal results. Stent malapposition and strut uncoverage, predictors of stent thrombosis, are frequently detected in STEMI patients at medium/long-term follow-up. Nevertheless, data at a short follow-up are missing. We aimed to assess the extent of stent malapposition and struts coverage in the subacute phase of STEMI after stent implantation in primary or rescue percutaneous coronary intervention (PCI).

Methods

STEMI patients undergone primary or rescue PCI and scheduled for a second coronary angiography after 2–7 days were enrolled. During the second procedure, frequency domain optical coherence tomography (FD-OCT) was performed to assess percentage of malapposed struts (MS%), percentage area of malapposition (MA%), percentage of uncovered struts (US%), percentage area of atherothrombotic prolapse (PA%) and optical coherence tomography thrombus score (OCT-TS).

Results

Twenty patients were included and 21 stents (19 865 struts) were evaluated. Strut uncoverage was relatively limited [US% = 11.1 (8.1–13.6) %]. Stent malapposition was observed frequently, even if at low degree [MS% = 6.4 (3.3–13.3) %, MA% = 1.80 (0.46–2.76) %] as well as atherothrombotic prolapse [PA% = 0.09 (0.00–1.06) %]. Both MA% and PA% were significantly related to residual OCT-TS (R = −0.52, P = 0.02 and R = 0.71, P < 0.001, respectively), use of thrombolysis (P = 0.001 and P = 0.004, respectively) and time elapsed from PCI to FD-OCT analysis (P = 0.001).

Conclusion

In the subacute phase after stenting in STEMI patients, strut uncoverage is relatively limited, while stent malapposition and atherothrombotic prolapse are common albeit limited features. Residual thrombus burden influences the degree of both stent malapposition and atherothrombotic prolapse.

Authors: Daniella Dian
Published: December 2018

Tuberculosis is a serious health problem not only in Indonesia, but worldwide. Each year, it occurs in nearly 9.7 million people and claims about 2 million lives worldwide. Pancreatic tuberculosis is a rare type of extra pulmonary tuberculosis that only occur less than 4.7% worldwide. The most common symptoms is abdominal pain and most of the patients shows abdominal tenderness on palpation. Diagnosis of pancreatic tuberculosis consist of tuberculin skin test, ultrasonography, computed tomography-scan, magnetic resonance imaging and biopsy. Diagnosing pancreatic tuberculosis is a challenge because of its rarity and it has similar symptoms as more common pancreatic condition such as pancreatic malignancy. Understanding of pancreatic tuberculosis will increased the clinical awareness that may guide clinicians to avoid unnecessary diagnostic or therapeutic procedures and early diagnosis.

Published: December 2018

Background: The inflammatory process has an important role in the pathophysiology of hepatic encephalopathy (HE) in liver cirrhosis. IL-18 is a key mediator who plays a role in neuroinflamation processes that can lead to symptoms of HE. This study aimed to determine serum IL-18 levels in liver cirrhosis patients and to assess the association of serum IL-18 levels with HE.Method: A total of 52 subjects (32 patients with liver cirrhosis and 20 healthy controls) were enrolled in this study. Thirty two (32) patients with liver cirrhosis will be assessed for HE based on West-Haven criteria. All subjects were examined for serum IL-18 levels which is measured by ELISA method. We performed a comparative analysis between serum IL-18 levels of liver cirrhosis patients and healthy controls, a correlation analysis between serum IL-18 levels and HE, and a comparative analysis of serum IL-18 levels among degrees of HE.Results: Mean serum IL-18 levels in the liver cirrhosis group were 688.5 ± 674.3 pg/mL, and in the healthy controls group were 163.9 ± 100 pg/mL with p value = 0.01 (p 0.05). There was a significant correlation between IL-18 and HE (r = 0.85; p = 0.00). Serum IL-18 levels in covert and overt HE groups were significantly higher than those without HE (p 0.05).Conclusion: Serum IL-18 levels were significantly higher in liver cirrhosis patients than in healthy controls. There was a positive correlation between IL-18 and HE. Serum IL-18 levels in liver cirrhosis patients with HE were significantly higher than those without HE.

Background: Active Helicobacter pylori infection is considered to cause more severe dyspepsia symptoms compared to inactive infection. This study was aimed to determine the association between severity of dyspepsia and urea breath test (UBT) results in subjects with positive H. pylori serology.Method: This study was a cross-sectional study in 60 subjects with positive H. pylori serology in Provincial General Hospital of West Nusa Tenggara. Severity of dyspepsia was measured using modified Glasgow Dyspepsia Severity Score (GDSS) questionnaire. Diagnosis of active H. pylori infection was made using 14C UBT examination.Results: Proportion of active H. pylori infection in subjects with positive serology was 20%. The average of modified GDSS score in all patients was 1.95 (SD + 1.78), with minimal score of 0 and maximal score of 7. There was a statistically significant difference between average of modified GDSS score and positive and negative UBT results, (p = 0.027). The cut-off point value of modified GDSS to diagnose positive UBT was 3.8. Results of diagnostic test with modified GDSS as a test and UBT results as the gold standard indicated sensitivity of 41.6% and specificity of 85.4%. Conclusion: There was a significant difference between modified GDSS score in patients and positive and negative H. pylori infection. In areas which did not have UBT examination, eradication in patients with positive serology and GDSS score of more than or equal to 4 could be considered.

Antioksidanlar,
insanlarda normal fizyolojik durumlarda oluşan, lipid peroksidasyonuna, protein
ve DNA hasarına, hücrelerin ölümüne ve bazı hastalıkların oluşumuna sebep olan
serbest radikallerin olumsuz etkilerini azaltırlar. Bu nedenle sağlıklı,
kaliteli bir yaşam için antioksidanlar ve oksidanlar arasında bir denge olması
gerekir. Bu noktada gıdalardaki antioksidanlar önem arz etmektedir. Bu
çalışmada, dengeli beslenmede önemli bir yeri olan sütün farklı hayvan
türlerine göre içerdikleri total antioksidan kapasitelerinin araştırılması
amaçlanmıştır.

Çalışma
da koyun, keçi ve inek olmak üzere üç farklı hayvan türünden elde edilen sütler
kullanılmıştır. Her bir tür için 10 farklı hayvandan süt numunesi toplanmıştır.
Süt numunelerinin asitlik tayini, yağ tayini, kuru madde tayini ve dansite
ölçümü yapılmıştır. Daha sonra sütlerin total antioksidan kapasitesi ölçümleri
için plazmaları kazanılmış, ticari kit kullanılarak ELISA yöntemi ile total
antioksidan kapasite ölçümleri yapılmıştır.

Kuru
madde, laktik asit ve yağ miktarı en yüksek olan sütün koyun sütü (p<0,05)
olduğu, dansitesi en düşük olan sütün ise inek sütü olduğu görülmüştür
(p<0,05). TAC’ı en düşük olan süt ise koyun sütü olarak bulunmuştur.
(p<0,05).

Buna
göre sütlerin total antioksidan
kapasitesi, elde edildiği hayvanın türüne ve sütün içerdiği laktik asit, yağ ve

Published: December 2018

The research aims to enlight the overview about the urgent of the Broad Guidelines of State Policy (GBHN) as the product of the People’s Consultative Assembly (MPR) by using the dogmatic approach. The amendment of the 1945 Constitution has changed the Indonesian constitutional system. According to the article 2 paragraph (1) of the 1945 Constitution, highest authority remains in the hands of the people and is carried out according to the Constitution. The constitutional design of the Indonesian government system is presidential. However, the implementation often reaps many obstacles and problems, the consequences of amendments, eliminating the authority of the People’s Consultative Assembly (MPR) in terms of electing the President and Vice President, and determining the Broad Guidelines of State Policy (GBHN). MPR is no longer placed as the highest institution of the country and the perpetrators of popular sovereignity. The Constitution which is the holder of popular sovereignty in the practice adheres to a clear and strict understanding of the separation of powers. Like in the legislative field there are People’s Consultative Assembly (MPR), House of Representatives (DPR) and Regional Representative Board (DPD); in the executive field there are Presidents and Vice Presidents elected by the people; in the judicial sector there are the Supreme Court, the Constitutional Court and the Judicial Commission; in the field of financial supervision there is a Indonesian Supreme Audit Institution (BPK). Changes in the position, function and authority of the MPR have implications for the emergence of the National Development Planning System and the National Long-Term Development Plan which became the authority of the elected President. The President that won the election as a basic guidelines for implementing development as the replacement of the GBHN.

A ação do ensinar tem, historicamente, a atenção, dos educadores e estudiosos sobre as abordagens pedagógicas, voltada para o processo de ensinar e aprender. Apreciar esse processo para a formação humana, para além da mecanização da aprendizagem, requer partir dos saberes culturais e do conhecimento sistematizado. Este estudo objetiva apresentar a sistematização pedagógica como possibilidade teóricoprática a ser adotada pelo professor. Aportado teoricamente no conceito do diálogo e na teoria crítica, propõe abordagem da ação do ensinar e aprender na perspectiva crítico-reflexiva. Trata da produção teórica sobre o tema e das experiências com a docência com o procedimento metodológico de diário de campo e reunião de material do acúmulo na práxis interventiva em ambientes educativos. Enuncia a abordagem denominada AAC- Abordagem da Ação Crítica. Conclui que é a apropriação epistemológica pelo professor que promove a ação do ensinar aprender mais do que o domínio de técnicas pedagógicas.

STUDI LABORATORIUM PENGARUH PENAMBAHAN RETARDER ( HR-7 ) TERHADAP WAKTU PENGERASAN & KUAT TEKAN PADA SEMEN PEMBORAN KELAS G

Salah satu masalah yang dihadapi pada saat melakukan penyemenan adalah pada kondisi sumur yang dalam dan temperatur tinggi semen cepat mengeras pada saat pemompaan dari permukaan menuju annulus. Semakin bertambahnya temperatur, bubur semen akan lebih cepat kering dan mengeras. Oleh karena itu, untuk mengatasi hal tersebut maka desain semen pemboran memerlukan additif yaitu retarder.Pada penelitian yang dilakukan ini, retarder yang digunakan adalah Sodium Lignosulfonate.Pada percobaan ini akan diamati bagaimana pengaruh penambahan retarder terhadap sifat fisik semen pemboran, yaitu kuat tekan (Compressive Strength) dan waktu pengerasan (Thickening Time) pada semen kelas G, sehingga akan diperoleh gambaran seberapa besar komposisi retarder yang optimal yang harus ditambahkan pada semen pemboran.Dari beberapa kali percobaan, terlihat bahwa semakin meningkatnya konsentrasi aditif retarder HR-7 pada komposisi bubur semen, maka nilai waktu pengerasan akan semakin rendah atau bubur semen akan lebih cepat mengeras akan tetapi pada penambahan konsentrasi aditif 1,5 % pada temperature 38 oC dan 1,75 % pada temperature 80 oC terjadi peningkatan atau bubur semen mulai memperlambat proses pengerasannya. Nilai kuat tekan akan meningkat, tetapi sampai dengan penambahan konsentrasi aditif 1,25 % pada temperature 38 oC dan 1,5 % pada temperature 80 oC saja, karena mulai dari konsentrasi aditif 1,5 % pada temperature 38 oC dan 1,75 % pada temperature 80 oC nilai kuat tekan akan semakin menurun. Temperatrue mempengaruhi sifat fisik semen pemboran dapat dilihat bahwa pada temperatur 38 Cmenunjukkan nilai compressive strength yang cenderung lebih kecil, kemudian thickening time yang lebih lama jika dibandingkan dengan hasil percobaan pada temperatur 80 °COleh karena itu, diperlukan komposisi semen pemboran yang sesuai dengan kondisi dari sumur pemboran

Kehilangan panas atau sering di sebut heat loss adalah salah satu masalah yang selalu di jumpai pada bagian pipa di lapangan panas bumi.Kehilangan panas bisa terjadi akibat perbedaan suhu antara uap yang mengalir di dalam pipa dengan suhu udara di luar pipa.Dengan persamaan yang dikembangkan oleh Frank kreith, perhitungan kehilangan panas membantu dalam perencanaan pemasangan insulator pada pipa sehingga pipa tidak mengalami kehilangan panas yang tinggi. Mencegah kehilangan panas sangat penting sebab turunnya suhu akan mengakibatkanperubahan fasa, dari fasa uap menjadi fasa cair (kondensat).Selain hal tersebut, energi berada dalam bentuk panas yang di bawa oleh fluida (air atau uap) apabila kehilangan panas besar , energi yang akan masuk kedalam turbin semakin kecil sehingga pada akhirnya mempengaruhi efisiensi pembangkitan listrik. Didalam tulisan ini, sebagai bahan material di ambil 4 macam, yaitu : Aerogel, Kalsium silikat, Glasswool, dan Rockwool. Keempat material tersebut memiliki konduktivitas yang berbeda-beda dalam arti kemampuan untuk menghantarkan panas untuk setiap jenis material berbeda-beda.

Lapangan X merupakan lapangan yang terletak di sebelah utara Pulau Jawa.Lapangan ini pertama kali ditemukan pada tahun 1968 melalui pemboran eksplorasi pada daerah tersebut.Produksi minyak Lapangan-X pertama kali terjadi pada tahun 1972 melalui salah satu platform yang dikembangkan pada Lapangan-X.Lapangan-X dikembangkan dengan menggunakan 13 platform dimana setiap platform terbagi menjadi beberapa sumur.Lapangan ini memiliki luas area sebesar 9kmx4km. Produksi minyak maksimum Lapangan –X sebesar 38000 BOPD pada tahun 1973 dan lapangan ini memiliki OOIP sebesar 567.1 MMSTB dan OGIP sebesar 317 BCF. Produksi kumulatif minyak saat ini adalah 133.8 MMBO dan produksi kumulatif gas sebesar 176.4 BCF.Untuk menganalisa optimasi injeksi gas lift pada Lapangan-X maka dilakukan variasi laju injeksi gas yang diinjeksikan.Simulasi penginjeksian gas dilakukan dengan penggunakan software PIPESIM.Dengan menggunakan perangkat lunak ini, dapat dilakukan matching dari data Uji Sumur dengan laju alir fluida di sumur-sumur tersebut. Setelah laju alir fluida pada Sumur Y,V, dan J matching, maka dapat dilakukan optimasi terhadap sumur gas lift dengan variasi injesksi gas.Tahapan optimasi dilakukan dengan menggunakan asumsi harga minyak yang dihasilkan sebesar U$S90/bbl dan biaya gas yang diinjeksikan dihargai sebesar U$S 2/MSCF.Dengan asumsi tersebut dapat dianalisa keuntungan optimum yang diperoleh dari nett revenue yang merupakan selisih antara harga jula minyak dengan biaya gas yang diinjeksikan. Jumlah injeksi gas yang optimum adalah jumlah injeksi gas yang menghasilkan nett revenue yang maksimum

Perhitungan Initial Gas In Place (IGIP) pada Lapangan KIM menjadi langkah awal pengembangan sumur gas. Untuk mendapatkan nilai setiap parameter perlu dilakukan interpretasi secara kualitatif maupun kuantitatif. Interpretasi data secara kualitatif meliputiquick look pada kurva log. Sedangkan interpretasi data secara kuantitatif adalah melakukan perhitungan berdasarkan data geologi, petrofisik, dan reservoir dengan menggunakan rumus-rumus tertentu. Dalam pengerjaannya, softwarePetrel dan Interactive Petrophysics digunakan untuk membantu analisis setiap parameter.Lapangan KIM memiliki dua lapisan yang berpotensi mengandung gas yaitu b2-340 dan K-670.Jenis lithologi pada lapangan ini didominasi oleh sandstone. Volume gas awal di tempat atau Initial Gas In Place (IGIP) pada lapisan b2-340 dan K-670 adalah sebesar 4.63 bscf dan 13.01 bscf. Sehingga volume gas awal di tempatatau Initial Gas In Place (IGIP) pada kedua lapisan di lapangan KIM adalah sebesar 17.63 bscf.

Uji sumur adalah uji aliran fluida di dalam sumur untuk mendapatkan data dan informasi properti sumur. Uji sumur dilakukan sebelum eksploitasi reservoir, juga setelah suatu periode produksi, untuk melihat apakah atau seberapa besar perubahan properti reservoir akibat eksploitasi (produksi atau injeksi).Terdapat beberapa pendekatan & metoda uji sumur, untuk menganalisa uji sumur untuk estimasi kapasitas suatu lapangan panasbumi, salah satunya adalah Metoda Separator, merupakan metoda yang paling akurat untuk mengukur aliran 2-fasa dari sumur panasbumi (Bangma, 1961). Laju air diukur menggunakan sharp-edged weir setelah flashing pada tekanan atmosfir, dan laju aliran uap diukur menggunakan orifice platepada tekanan separator (Grant & Bixely 2011).Uji produksi dengan Metoda Separator telah dilakukan pada sumur-sumur di Lapangan panasbumi “X” yang menyuplai uap ke PLTP unit 1 & 2 , 2x55 MW yang dioperasikan oleh PLN.Studi ini berjudul: “Optimasi Deliverabilitas Sumur-Sumur Geothermal di Cluster C Dengan Mempertimbangkan Skenario Penurunan Produksi”, bertujuan untukanalisisdata uji produksi yang kemudian digunakan untuk menentukan kurva deliverabilitas optimum sebagai dasar analisis penentuan jumlah sumur make up optimum. Skenario decline ratemengacu pada Lapangan panasbumi Kamojang sebesar 6,4% (Suryadarma et al.2005). Pada skenario decline 1-10% selama selang waktu 30 tahun, adalah: 1, 3, 5, 7, dan 9.

SARISimulasi reservoir merupakan bagian dari ilmu teknik perminyakan, khususnya teknik reservoir dimana model komputer digunakan untuk memprediksikan aliran fluida melalui media yang bersifat porous. Proses suatu simulasi reservoir dimulai dengan beberapa langkah, yakni preparasi data, pembangunan model beserta grid, inisialisasi, penyelarasan data produksi dengan simulasi (history matching)., serta prediksi performance produksi model yang disimulasikan. Proses inisialisasi dilakukan untuk menyesuaikan nilai OOIP atau total hidrokarbon awal yang mengisi reservoir dengan nilai OOIP awal pada model static.Untuk mendapatkan peramalan kinerja produksi yang akurat, rencana pengembangan Lapangan TR Lapisan X dilakukan dengan memprediksikan kinerja reservoir untuk berproduksi selama 30 tahun (sampai dengan Januari 2044). Pengembangan yang direncanakan pada penelitian ini berjumlah 4 skenario, yang terdiri dari skenario 1 (Base Case), skenario 2 (Base Case + Reopening sumur yang non-aktif), skenario 3 (skenario 2 + Infill sumur produksi), skenario 4 (Skenario 2 + infill sumur injeksi pola 5 spot).ABSTRACTReservoir simulation is an area of reservoir engineering in which computer models are used to predict the flow of fluids through porous media. Reservoir simulation process starts with several steps; data preparation, model and grid construction, initialization, history matching and prediction. Initialization process is done for matching OOIP or total initial hydrocarbon which fill reservoir with hydrocarbon control volume with volumetric method.To aim the best encouraging optimum data, these development scenarios of TR Field Layer X will be predicted for 30 years (from 2014 until January 2044).

Studi ini bertujuan untuk mengetahui dampak fluktuasi harga minyak di pasar dunia terhadap harga minyak Indonesia melalui data runtun waktu dari harga rata-rata minyak dunia dan harga rata-rata minyak Indonesia. Melalui koefisien korelasi dalam ilmu statistik, data runtun waktu dari kedua variabel harga rata-rata minyak dunia dan harga rata-rata minyak Indonesia diperoleh nilai 0,91, harga ini mendekati nilai +1 yang berarti menunjukan hubungan yang kuat antara dua variabel yaitu harga rata-rata minyak dunia dengan harga rata-rata minyak Indonesia. Meningkatnya harga minyak Indonesia tentu akan berdampak buruk pada perekonomian dalam negeri, oleh karena itu perlu adanya perhatian pemerintah untuk menempuh langkah-langkah yang bisa mengubah kebiasaan masyarakat yang semula boros BBM menjadi hemat BBM. Selain itu, dibutuhkan pula kebijakan dalam mendorong pengembangan energi alternatif.Kata kunci: minyak, ekonomi, harga
