Aliran masuk ke Danau Towuti, Kabupaten Luwu, Sulawesi Tengah, dianalisa dengan artificial neural network. Network mempunyai susunan yang terdiri dari 6 node pada layer input, 8 node pada hidden layer, dan 1 node pada layer output. Weight dari network dihitung dengan back propagation of error dan fungsi Sigmoid dipakai sebagai fungsi aktifasi. Dari analisa ditemukan bahwa curah aliran masuk (inflow) sangat dipengaruhioleh curah hujan di daerah-daerah Wawondula, Dam site, Timampu, Palumba, Loehadan Bantilang. Dari ke 6 derah tersebut, perubahan curah hujan di Wawondula mempunyai pengaruh yang sangat kuat terhadap inflowArtificial neural network method was applied in analyses of inflow to Towuti Lake of LuwuRegency, Central Sulawesi. The network was constructed by 6, 8, 1 nodes in input, hidden and output layers. The weights were calculated using back propagation of error and Sigmoid function was used as activation function. It was found that precipitations at Wawondula, Dam site, Timampu, Palumba, Loeha and Bantilang have the strongest influence to the inflow. Of the 6 areas, the precipitation changes at Wawondula has thestrongest effect to the change of the inflow

Arah dan kecepatan angin selain berpengaruh terhadap pergerakan dan perkembangan awan, juga berpengaruh terhadap pergerakan masa udara di daerah sasaran dan sekitarnya. Kondisi kecepatan angin yang tinggi akan menyebabkan bergeraknya awan potensial di dalam target ke luar target. Atau dapat dikatakan dengan kecepatan angin yang tinggi di dalam target akan memperkecil jumlah hujan. Tulisan ini mengkaji kejadian hujan berkaitan dengan arah dan kecepatan angin yang terjadi selama penerapan Teknologi Modifikasi Cuaca di Sub DAS Kali Brantas bulan Jan â Peb 1998.Wind direction and velocity influenced cloud movement and development as well as air mass movement in target area and its surrounding. High wind velocity results in the movement or escape of potential cloud from the target erea. In other words high wind velocity in target area decreases precipitation amount. This paper discusses the relationship between precipitation occurrence and wind direction and velocity during the cloud seeding activity in Brantas Catchment Area in January â February 1998

Teknologi hujan buatan (modifikasi cuaca) pada dasarnya memberikan suatuperlakuan terhadap alam yaitu dengan menaburkan suatu zat ke awan di udara,sehingga kemungkinan menimbulkan masalah-masalah lingkungan. Analisa dilakukansecara kualitatip yaitu dengan membandingkan data hasil analisa kualitas air denganbaku mutu air untuk golongan A yang diperuntukkan sebagai air minum berdasarkanPP No. 20 tahun 1990. Disamping itu juga data dibandingkan dengan persyaratankualitas air yang diperuntukan bagi keperluan pertanian maupun perikanan menurutberbagai referensi maupun baku mutu air golongan C. Hasil analisa dapat disimpulkanbahwa perlakuan hujan buatan tidak mempengaruhi kualitas air hujan. Tidak terdapatperbedaan yang nyata kualitas air hujan buatan pada periode sebelum, selama dansetelah hujan buatan. Kualitas air hujan (untuk parameter uji pH,DHL, Nsa, Cl, Ca,NO2, No3, dan NH4) selama hujan buatan masih dalam batas-batas toleransi yangditetapkan sesuai dengan baku mutu air golongan A. Kualitas air hujan buatan layakdiperuntukkan bagi pertanian dan perikanan.Rain making (weather modification) basically is a treatment by spreading a chemicalsubstance into the cloud, therefore some environmental issues may be arised due tothis operation. Analysed have been carried out qualitatively by comparing rain waterquality analysis to A-type standard water quality which is intended for A type drinkingwater based on Government Regulation PP No. 20 year of 1990. Besides the data wasalso compared to water quality standards for agricultural and fisheries based onseveral references as well as C - type water quality standard. The results of this studyshows the treatment by weather modification does not influence the quality of rainwater. There is no significant difference of rain water from the periods of before, duringand after the operation. Rain water quality (such as pH, Conductivity, Nsa, Cl, Ca,NO2, No3, and NH4) during the operation is within the allowed tolerances of the A-typewater quality standard. The quality of the rain water during the operation is usable foragriculture and fisheries.

Pusat Pengetahuan Radio Atmosfer dan Antariksa, Universitas Kyoto, Jepang bekerjasama dengan Lembaga Penerbangan dan Antariksa Nasional (LAPAN) telahmembangun suatu radar VHF raksasa yang diberi nama Radar Atmosfer Katulistiwa (EAR) di Kototabang, Bukittinggi, Sumatera Barat. Perhatian utama radar ini adalah untuk meneliti perilaku angin dan turbulensi yang terjadi di lapisan troposfer dan lapisan bawah stratosfer dengan resolusi tinggi dalam waktu dan ketinggian. Beberapa program studi dan penelitian yang berkaitan dengan penggunaan data radar ini sedang direncanakan. Pada makalah ini latar belakang berdirinya EAR, gambaran umum tentang EAR dan MU radar, sistem kerja, hasil awal beroperasinya EAR di Indonesia, khususnya vertikal profil angin zonal dan meridional dikemukakan untuk dibahas.Radio Science Center for Space and Atmosphere (RASC) of Kyoto University (Japan) together with the Indonesian National Institute of Aeronautic and Space (LAPAN) have been constructed a giant VHF radar, namely Equatorial Atmosphere Radar (EAR) at Kototabang, Bukittinggi, West Sumatera. This radar is mainly concerned to observe winds and turbulence in the troposphere and lower stratosphere with a good time and spatial height resolution. Numerous study and research programs with the EAR are now planed. In this paper the basic idea the contructed of EAR, the general description of EAR and MU radar, working system and an initial observation results of EAR contruction, especially on the vertical profile of zonal and meridional wind velocity are discussed.

In realizing modern tax administration system that the government provide an application that can be used for charging the taxpayer, reporting notification letter (SPT) is precise, fast, and secure. The purpose of this study was to analyze the implementation of e- filing as an effort to increase tax compliance in the delivery of a notice (SPT) Annual taxpayer on STO Pandeglang.This study used a qualitative approach, by conducting a case study. by analyzing and understanding the issues related to tax compliance in the submission of their annual tax return taxpayer, analyze, investigate, and determine conclusions. Results of research showed there are some findings that an increase in the delivery of a notice (SPT) in 2015 and increased taxpayer compliance rate in 2015. It can be concluded that the implementation of e-filing can improve taxpayer compliance in the submission of annual returns taxpayers in KPP PRATAMA PANDEGLANG.

This research aims to test the impact of integrity and ethical values, commitment to competence, Tone at the Top, work culture, organizational structure, Sop and supervision of the findings of the Internal Auditor Regional Water Company (PDAM) in the province of Banten. The samples in this study using purposive sampling method. Data were collected using a questionnaire survey techniques. The target respondents of this study were 100 respondents, but the data is data that can be processed is 83 respondents. To test the quality of the data from the instrument used to do with the validity and test ralibilitas. Test the classical assumption of normality test, multicollinearity, homogeneity test and test heterkodastisitas is intended as a requirement to perform multiple linear regression test. The results of multiple regression analysis showed that the variation of the variable findings of the internal auditor can be explained by the variable of integrity and ethical values, commitment to competence, tone at the top, work culture, organizational structure, soup and supervision 52.9 percent, t test showed that the variables Integrity and ethical values, commitment to competence, Sop and Supervision affect the findings of the internal auditor, while variable Tone at the Top, Culture Work and Organizational Structure there are no influence against the findings of the internal auditor. The results of research shows that Integrity and Ethics Values, Commitment Competence, SOP and Oversight had a positive influence on the Findings of the Internal Auditor. The test results provide a synthesis hypothesis that the better Integrita and ValuesEthics, Commitment Competence, SOP, and the stronger the less oversight findings of internal auditors found (fewers error)
