This study aims to explain the current dispersion of tuberculosis (TB) and provide evidence that could help predicting its future transmission in Daerah Istimewa Yogyakarta (DIY) Province, Java Island, Indonesia. One hundred thirty-two adult (>14 years old) individuals, with TB diagnosed by health professionals using the Directly Observed Treatment, Short Course strategy, were identified Their residential addresses and geographical patterns of movement were investigated by global positioning systems and descriptive spatial analysis using standard deviation ellipse analysis and kernel estimation. The dispersion of TB cases was studied by ellipse regression, which showed a pattern extending in a direction oriented from north-west to south-east centred on Kasihan District, Bantul Regency, DIY Province, located near Yogyakarta City. Levels of TB risk in the study area varied from non-existent to high as calculated by kernel estimation. We conclude that suburban communities, followed by densely populated residential areas, enabled by socio-economic factors, are more likely to see increased TB transmission in the future.

MPD (Managed Pressure Drilling) has been used worldwide to overcome drilling challenges in onshore and offshore operations. MPD has proven to save significant cost efficiency in every applications, by reducing NPT (Non Productive Time) caused by drilling problems such as, severe loss circulations, loss-kick cycle, and well control events. Indonesia is one of major country in Asia Pacific that has several needs to developing or exploring new opportunities with drilling challenges, especially in vuggular carbonate reservoirs, narrow drilling windows, and wellbore in-stability. This paper will present the basic theory on MPD, MPD equipment’s, types of MPD, and elaborate more on successful MPD operation in onshore Indonesia, and clustering the solutions of drilling challenges.

<p><span style="font-size: medium;">Ketika temperatur <em>crude oil </em>berkurang, komponen-komponen berat seperti paraffin/<em>wax</em> (C18 – C60) akan terpresipitasi dan mengendap pada dinding pipa. Pengendapan <em>wax</em> dapat menyebabkan diameter internal pipa berkurang dan pipa tersumbat. Laju produksi yang rendah dapat mempengaruhi terjadinya deposit <em>wax</em> karena waktu tinggal (<em>residence time</em>) minyak yang lama di pipa. <em>Residence time</em> minyak yang lama, menyebabkan adanya <em>heat loss</em> dari fluida, sehingga menurunkan temperatur minyak saat mengalir. Penelitian ini dilakukan dengan tujuan untuk memprediksi kedalaman terbentuknya <em>wax</em> pada sumur X. Untuk mengetahui kedalaman terbentuknya wax pada sumur X, yaitu dengan memplot hasil prediksi distribusi tekanan dan temperatur per kedalaman kedalam kurva <em>wax deposition envelope</em>. Fase <em>wax</em> pada sumur X akan muncul pada temperatur 131 °F dan tekanan 343 psi di kedalaman 300 ft dari kepala sumur dan pada saat tekanan statis reservoir mencapai 1752 psi.</span></p>

Effluent digester is potential to be composted by adding organic material (organic waste, etc.) and to accelerate maturity, inoculant effective Microorganism (EM) is required as bio decomposer in fermentation. Not only to break the chain of diseases, this organic fertilizer also economic value, sold as agricultural fertilizer.The purpose of this study is to use the effluent of biogas digester for making compost. This experimental research method using a randomized design consisting of 4 formulations each treatment replicated 3 times with 30 days maturation and the compost will be carried out physical and chemical assessment. The results showed that compost with biogas effluent material: charcoal secam: sequential organic waste with a ratio of formulas: 1 (4: 1: 1); 2 (3: 1: 1); 3 (2: 1: 1) and 4 (1: 1: 1). Physical assessment of the 4 formulas, namely temperature, pH, humidity, color, odor and texture meet the requirements of SNI 19-7030-2004. Measurement of the chemical content of formula 1 (content C: 14.36%; N: 0.98; P: 1.27; K: 1.11; C/N ratio: 14.78); 2 (content C: 17.85%; N: 2.06; P: 1.21; K: 0.88; C/N ratio: 16.91); 3 (content C: 16.14%; N: 0.84; P: 1.02; K: 1.10; C/N ratio: 14.78); 4 (content C: 16.42%; N: 0.89; P: 1.15; K: 0.88; C/N ratio: 18.52). The more use of biogas effluent produced compost with N, P, K the greater is followed by a decrease in C/N ratio and met the requirements of SNI 19-7030-2004. The results of this study can be implemented by, from and for the community, in making compost that is economically beneficial, can reduce the expenditure of chemical fertilizers. renewable energy substitutes for LPG easily and at relatively low costs.
