Tempat-tempat Terkini Yang Disenangi Untuk Perkembangbiakan Vektor Demam Berdarah Aedes SP.
Aedes aegypti and Ae. albopictus are known as the vector of dengue and chikungunya. The breeding habitat of dengue vector Aedes, were studied using larva collection method inside and outside houses in Pondok Aren and Curug sub districts in Tangerang area (as zone I), Kebayoran Baru and Kebayoran Lama in Jakarta Selatan area (as zone II) and in Bekasi Timur, Cibitung and Tambun sub districts in Bekasi area (as zone III). Study was carry out during December 2007-March 2008, by identification the Aedes breeding places. The characteristics of containers and larvae in each container were recorded. The result of species identification shown of 94% of the 137 containers with positive with mosquitoes larvae, were positive with Aedes aegypti, so was dominant species. Their breeding habitat likely in cistern, in darkly situation and 6-10 liters in volume were the most common as breeding habitat of Aedes in all zonas surveyed. The breeding habitats pattern of Aedes aegypti in this study similar to those of others previously studies. Thereover, the study result that the larval Aedes aegypti was founded in two storage water on dispensers

Competitiveness Towards ASEAN Economic Community
ASEAN Economic Community will be the driving force of an economic integration within ASEAN countries, and between ASEAN countries and the rest of the world. Many believe the economic integration will realize ASEAN framework as a single market and production base, to increase competitive economic region, to support more equitable economic development, and as a stepping stone toward full integration into globaleconomy. Commitments of the implementation of AEC Blueprint by ASEAN member countries will be a crucial role to achieve the objective of the ASEAN Vision, Mission, and Targets
The Use of Deadline Not, Cloud Storage, and Google Calendar as a Helpful Device in Managing Daily Agenda for Indonesian Students
Indonesian students have a lot of activities, in addition to the lecture there is activity of the organization, part time work, and more. This requires students to be able to manage time well. Time management is the key for effective management. One of things that support student activities are information technology such as the internet. The internet can help student’s time management agenda. Internet applications that support management time is cloud storage and Google calendar. The kind of research which is used is combination descriptive and quantitative research with primary data comes from research conducted by the writer and secondary data comes from literature review. Collecting data technique which is used in this paper is online questionnaire and document analysis technique. The population of all the semester students from various universities in Indonesia, with a random sampling method. While, the review and analysis of documents were obtained from various printed and electronic media which are relevant to the subject matter studied. In this research the analysis model uses is the equations of questions frequency. Based on the results of this research is that 89% of students join the organization, 74% chose the notes rather than recall when finding the idea, 51% choose to typing in gadgets in a hurry, 80% using a pocket-sized notebook to their agenda notebook. 100% have personal gadgets, 94% regularly access the internet, and 89% require a tool in time management. A total of 100% need to assist IT management daily agenda. Based on the results and discussion of this paper, it can be concluded that the usage of deadline note, cloud storage, and Google calendar for Indonesia students can be a solution to the helpful device in managing daily agenda.

Studi Q-EEG: Analisis Konektivitas Fungsional Otak Pada Anak Autism Spectrum Disorder (ASD)
Autism Spectrum Disorder (ASD) mengacu pada gangguan perkembangan syaraf yang ditandai dengan adanya kesulitan komunikasi sosial dan perilaku yang berulang. Kondisi pada penderita ASD ini berkaitan dengan gangguan konektivitas fungsional dan struktural otak. Tujuan penelitian ini adalah menganalisis perubahan konektivitas fungsional otak dengan menggunakan metode quantitative electroencephalography (Q-EEG). Parameter fisis yang dikaji berupa fase sinkronisasi sinyal (phase sycronization) yang terdiri dari besaran Phase-Lag Index (PLI) dan weighted Phase-Lag Index (wPLI). Perekaman sinyal otak menggunakan Emotiv Epoc 14-elektroda (AF3, F7, F3, FC5, T7, P7, O1, O2, P8, T7, FC6, F4, F8, AF4) dan 2-elektroda referensi (CMS dan DRL). Subjek uji terdiri dari anak penderita ASD dan anak normal masing-masing sebanyak lima anak dengan rentang usia 10-15 tahun. Tahapan penelitian meliputi perekaman sinyal EEG, pre-processing data, dan pengolahan data. Analisis nilai PLI dan wPLI dilakukan pada lima rentang frekuensi gelombang otak (delta, theta, alpha, beta dan gamma). Berdasarkan hasil analisis perhitungan nilai PLI dan wPLI menunjukkan adanya penurunan konektivitas fungsional otak pada anak ASD di semua pita frekuensi. Penurunan konektivitas fungsional pada anak ASD yang signifikan berdasarkan hasil uji statistik, terjadi pada area otak intra-hemisphere kanan untuk frekuensi alpha
Rekonfigurasi Jaringan Distribusi Untuk Meminimalisasi Rugi-Rugi Daya Dengan Menggunakan Metode Grey Wolf Optimizer (GWO)
Rekonfigurasi jaringan pada jaringan distribusi merupakan suatu proses atau usaha untuk mengubah status sakelar pada saluran yang terhubung (sectionalizing switch) dan yang tidak terhubung (tie switch) dengan tujuan untuk meminimalisasi rugi-rugi daya dan memperbaiki profil tegangan pada sistem. Rekonfigurasi dilakukan dengan mengganti jalur saluran baru yang terhubung tanpa menambah jumlah saluran. Namun, proses rekonfigurasi yang tidak tepat akan menyebabkan rugi-rugi daya menjadi lebih besar. Pada penelitian ini, metode Grey Wolf Optimizer (GWO) digunakan untuk melakukan rekonfigurasi yang optimal terhadap kasus sistem standar IEEE 33-bus dan sistem standar IEEE 69-bus. Hasil simulasi pada sistem standar IEEE 33-bus menunjukkan bahwa setelah dilakukan optimasi rekonfigurasi, rugi-rugi daya aktif pada sistem menjadi sebesar 139,5513 kW atau berkurang sebesar 31,146% dari sebelum rekonfigurasi, yaitu 202,6771 kW. Sedangkan pada sistem standar IEEE 69-bus, rugi-rugi daya aktif menjadi sebesar 98,6056 kW atau berkurang sebesar 56,1754% dari sebelum rekonfigurasi, yaitu 225,0007 kW. Dengan menggunakan metode GWO mampu mengurangi rugi-rugi daya aktif yang lebih baik dibandingkan dengan beberapa metode lain.

Zeoponic AS Growth Media Of Horticulture Plants
Hydroponic is a method to growing up plant on non soil plant growth media (PGM) such as water, sand, gravel, carbon etc which mixes with other materials needed to grow the plants. The weaknesses of PGM are the low buffering capacity on electrical conductivity which can disturb the absorbtion of nutrients by plants. This can be caused by the low cation exchange capacity rate on the holding capacity of the media on nutrients. PGM such as zeoponic is made from zeolite and other materials like compost, peat moss, vermiculite, fertilizer, etc. The superiority of zeolite namely high cation exchange capacity and fertilizing efficiency rate, suitable for seed germination media and horticulture plant growth media, stable and more attractive performance. With these superiority, zeoponic became an alternative PGM which potential to increase horticulture plant production and to accommodate germination, both plantation and forestry. More over zeoponic made hydroponic became much easier to be done

Oil Prices Sensitivity to The Power Supply Procurement Project at PT PEP Sukowati
This study intends to determine the sensitivity of changes in oil prices to investment in power supply projects from the financial aspect. The investment analysis conducted is an evaluation of Net Present Value (NPV) using the production sharing contract (PSC) model with a profit sharing system. Based on the analysis conducted, the sensitivity of changes in oil prices has a very significant effect on the project NPV. Changes in oil prices by 60% from the base case to US 20 or -60% from the base case, it will make the NPV negative, so the project is not economical to proceed. In addition, it know that the acceptance limit of investment in power supply projects is at oil prices greater than US $ 34 per barrel. This significant change in both the decline and increase in oil prices to the NPV is very logical because oil prices determine the amount of revenue earned from this project
