The occurrence of corrosion and scale on production equipment is an obstacle that often occurs in oil and gas exploration activities. Physical and chemical properties of formation water that come out with oil from production wells are the main variables causing corrosion and scale. In recent years, developing nanotechnology provides many benefits in various industrial activities. One product that is becoming widely known is Copper Nano Particles (CuNPs) which have anti-biotic, anti-microbial, and anti-fungal agents which are soluble in water and can be used to protect / coat metals (superficial conductive coatings of metal and non-ferrous metal). The use of nanoparticles in oil and gas exploration activities is still very limited. Specifically, the CuNPs material, its anti-bacterial and anti-fungal properties have never been researched on the possible use in the oil field. In this study, it was observed the influence of the presence of CuNPs in formation water on the potential for scale formation and corrosion. Formation water obtained from production wells in the Wonocolo region, Cepu, Central Java, is used as a sample to test the effect of CuNPs on the scale and corrosion trends. Observations have shown that the CuNPs content test at various concentrations did not have a significant effect on formation water for its tendency to form scales. While the corrosivity of water seems to be quite influenced by the presence of CuNPs, where the addition of nanoparticle material is optimal at 0.01 ppm which can reduce corrosion rates up to 95%.

One of the zeolite producing areas in Indonesia is Sukabumi. Natural zeolite originating from Sukabumi is composed of three main types of minerals: mordenite, clinoptilolite, and quartz. Zeolite as a catalyst can be improved by carrying out physical and chemical activation processes. Physically the catalyst can be activated by reducing the size of the zeolite through the grinding and sieving method. This physical activation process can increase the surface area of the zeolite. In this study, variations in the size of zeolite 80 mesh and 100 mesh were carried out that chemically activated by the acid activation method through immersion of natural zeolite with HCl and HF from this acid activation process it will increase the acidity of the zeolite. Measurement of functional groups and chemical compounds in activated zeolite using XRF and FTIR. The results of XRF analysis showed that the SiO2 content in 80 mesh zeolite was 69.5% and in 100 mesh zeolite was 82.1% and the FTIR analysis showed the presence of the C-H alkene functional group at a wavelength of 675-995 cm-1, ring C-H aromatic at a wavelength of 690-900 cm-1, C-O alcohol/ether/carboxylic acid/ester at wavelength 1610-1680 cm-1, functional group C=C alkene 1610-1680 cm-1, the O-H functional group is carboxylic acid at a wavelength of 3500-3650 cm-1 and an alcohol monomer/phenol O-H functional group at a wavelength of 3590-3650 cm-1.

Oil and gas productions are demanded more these days. The industries itself have to be creative in many ways to increase the productions. The industries have to take the risk no matter what to fulfill these demands including trying a few methods. Some of the techniques are brand new and there is always a possibility that it decreasing a production instead of increasing.TUNU Field has one of the biggest gas productions in the world and it belongs to Pertamina Hulu Mahakam. It is located in Mahakam River Delta of East Kalimantan, Indonesia. For almost 80 kilometers it is spread from north to south of the Mahakam River Delta and covering about 400 square kilometers. The reservoirs are characterized as multilayered reservoirs with perforated producing zones ranging from (MD) 700 m to 5100 m.Sand production in well is one of the obstacles that oil industries are facing when it comes to oil and gas productions. There is of course limitation to sand production; it can bring benefits to good performance in a suitable amount. It can also be completely harmful to a well or in producing oil and gas. To prevent a sand breakthrough, sand control is put to the test. In this paper, a new technique of sand control will be discussed along with its advantages and disadvantages. This new method is called sand consolidation.Before sand consolidation being treated, some criteria have to match the standard. If it does not meet the criteria, it could mean either the reservoir does not need a sand control or using a mechanical sand control. When a reservoir is ready to be injected with the sand consolidation treatment, there is some procedure to follow. With the different type of sand consolidation chemicals, the temperature of the reservoir is important to this operation. One wrong chemical can lead to failure.In sand consolidation, the velocity gas and the drawdown are being reviewed due to managing risk of the well's integrity and good productivity. To control sand successfully, several important objectives must be reached during consolidation. The primary objective of sand consolidation is to bond together the formation sand adjacent to every perforation. Considering the treatment is designed to function on formation sand a zone several feet in radius around the wellbore can be consolidated.Studies of consolidation failure mechanisms show that plastics for the treatment must be inactive to reservoir fluids, should have very quick curing days and must have a robust wetting property. Including the gas flow rate increases after the treatment. Keyword: Sand Consolidation

This study used CdS as a pair of TiO2 Nanotube Arrays (TNTAs), considering the position and width of the energy band gap, which is expected to increase photocatalyst performance. The nancomposite was synthesized using the successive ionic layer adsorption reaction (SILAR) method, with Cd(CH3COO)2 and Na2S as precursors. The CdS/TNTAs nanocomposite is expected to reduce the energy band gap to enable the visible and UV spectrum to activate the photocatalyst. Additionally, the formed heterojunction mechanism provides opportunities for the trajectories of electrons and holes to be farther apart and reduce the recombination rate. The degradation ability of CdS/TNTAs nanocomposite in the photocatalytic process was evaluated using samples of ciprofloxacin liquid waste as an antibiotic, which is quite challenging to decompose completely. The ability of the photocatalytic process to produce hydrogen gas was also observed and its performance synergized with the electrocoagulation process. The result showed that the use of CdS as a TNTAs partner in CdS/TNTAs nanocomposites affects increasing photocatalyst performance, both in degrading ciprofloxacin and producing hydrogen gas. Furthermore, the CdS/TNTAs nanocomposite increased the photocatalytic process’s ability to degrade ciprofloxacin and produce hydrogen from 8.5 to 20.5% and 6 to 23.5 mmol/m2 compared to using TNTAs alone. The processing capability is further enhanced when run in synergy with the electrocoagulation process where the removal of ciprofloxacin reaches 86.55% and the hydrogen produced is 2.62×106 mmol/m2.

Kegiatan pembudidayaan ikan lele dan tanaman hidroponik ini diajukan sebagai pelaksanaan salah satu dari tridarma perguruan tinggi yang merupakan kewajiban bagi dosen dalam bentuk pengabdian kepada masyarakat. Ide dari pelaksanaan pengabdian ini di dasarkan atas pentingnya pelatihan kewirausahaan bagi anak didik di Pondok Pesantren Fajrussalam Sentul. Pemilihan topic Pembudidayaan ikan lele dan sayuran hidroponik (budikdamber) dianggap sebagai pelatihan yang cukup menarik untuk dipraktekkan. Metode ini cukup baru dan cukup efisien dalam pelaksanaannya, karena dalam satu sistem bisa menghasilkan 2 produk. Bahan-bahan yang akan digunakan dipilih yang teknik pemasangan bisa dikerjakan sendiri, misalkan pembuatan lubang2 untuk tanaman sayuran dan pemasangan kran di samping bagian bawah ember dikerjakan sendiri supaya harganya bisa ditekan. Demikian juga pemilihan benih dan pakan akan dilaksanakan sebaik mungkin, karena akan mempengaruhi hasil panen. Pemeliharaan harian diatur sedemikian rupa sehingga semua anggota bisa berpartisipasi. Pada pelaksanaan PKM ini ada beberapa kendala yang dihadapi, yatu karena hawa terlalu panas dan kadang hujan terlalu deras, maka diutuskan untuk membuat rumah-rumahan pelindung bagi peternakan lele ini. Sehingga pelaksanaan menjadi terlambat karena harus membuat bangunan pelindung da juga harus memasang paving untuk dudukan dari meja tempat meletakkan ember.

One of the issues facing the planet is energy. Energy's significant role influences numerous local economic activities in society. To prepare for growing fuel prices, cheap, accessible alternative fuel is required. The strategy employed for this community service is socialization and training, and it is done offline (face-to-face) while still paying attention to the health program. This PkM task is broken down into multiple steps. Planning comes first, followed by gathering equipment and supplies, making briquette samples, and finally, implementing the strategy. The activity found that approximately 15 housewives participated in this PkM activity. Providing information about the energy sources needed in Indonesia and their use is part of this PkM's work program. The community service projects that have been completed are anticipated to have a beneficial impact on society and the environment, mainly on the locals of Gili Sampang Kebon Jeruk. The training participants were quite proactive during the activity, which can be proven from several questions to make alternative energy fuels good and maximum that the community can utilize. The PkM team and participants created a mutual agreement that synergizes with each other to develop alternative energy sources in the form of fuels that benefit the community.

Pondok Pesantren Fajussalam Bogor merupakan pondok yang cukup maju dan modern dengan perkembangan pembangunan sarana pendidikan yang sangat cepat. Demikian pula dengan kegiatannya pendidikan dan pengajaran sudah cukup maju terutama pendidikan agama sebagai pendidikan yang utama. Tetapi hasil dari dari hasil survey pada 10 Januari 2018 terhadap santri (murid laki-laki) dan santriah (murid perempuan) kelas 7 hingga kelas 9 diperoleh data-data yang menunjukkan kurangnya pendidikan eksakta bagi para murid-murid tersebut. Data juga menunjukkan ada beberapa kekurangan yang terdapat pada satuan pendidikan di pondok ini yaitu jam pelajaran untuk ilmu eksakta kurang dan jumlah ustadz (pengajar laki-laki) dan ustadzah (pengajar perempuan) yang mengajarkan ilmu eksakta juga kurang bahkan sarana belajarnya juga kurang memadai. Kami dari tim Pengabdian Kepada Masyarakat (PKM) Fakultas Teknologi Kebumian dan Energi (FTKE) Universitas Trisakti berusaha memberikan sedikit masukan pada masalah tersebut diatas, selain dari kewajiban kami untuk melaksanakan Tri Dharma Peruruan Tinggi yang harus kami laksanakan. Adapun usaha-usaha yang kami lakukan sudah berjalan selama 5 periode tahun akademik. Pertama penjelasan kepada para murid tentang pentingnya mempelajari ilmu eksakta, melaksanakan diskusi dengan para pengajar, memberikan masukan kepada pengurus pondok tentang jam pelajaran yang kurang, memberikan sumbangan-sumbangan yang berupa infocus, buku-buku pelajaran, alat-alat peraga dan diperkenalkan juga dengan pembudidayaan lele dan kangkung. Adapun manfaat yang bisa dirasakan oleh para siswa dan pengajar adalah para pengajar mendapatkan masukan-masukan cara pengajaran, mendapatkan tambahan media belajar berupa buku-buku dan alat peraga sehingga bisa meningkatkan pengetahuan dan ketertarikan mempelajari ilmu eksakta karena lulusan dari pondok ini selain menjadi ahli agama juga diharapkan sebagian mampu bersaing pada bidang eksakta.
