Abstract

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

Abstract

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.

Abstract

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 – 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 – February 1998

Abstract

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.

Abstract

The main focus of industry players now is the environment, where industry players are required to be more responsible for the environment as a result of their operating activities which incidentally intersect with the use of the environment, because one of the biggest contributions related to environmental problems is the fruit of industrial activities produced by companies such as waste or something else. This study aims to find out how much the application of green accounting and environmental cost analysis begins with identification, recognition, measurement, presentation and disclosure in the chemical industry company PT Nippon Shokubai Indonesia, this research is a qualitative research in the form of a case study. The results of the study stated that PT Nippon Shokubai Indonesia, had implemented Green Accounting accounting practices even though it was not what was expected, environmental management carried out by PT Nippon Shokubai Indonesia by processing waste was carried out by themselves using the Increator tool and if waste production was excessive the Company appointed a third party licensed in waste processing, especially for B3 waste, regarding reporting aspects PT Nippon Shokubai Indonesia has expense items related to social and environmental activities, but specifically reporting related to environmental costs has not been reported.

Abstract

The background of this research is that SME managers in preparing financial reports based on SAKETAP, the managers are given training and assistance by the Department of Cooperatives, SMEs,Industry and Trade of Serang City, but the managers still focus on production without payingattention to recording financial transactions, thus hindering the managers in carrying outdevelopment, evaluation, and decision making. The formulation of the research problem is whetherthere is an influence between the ability to prepare financial reports based on SAK ETAP on theperformance of SMEs and financial literacy as a moderating variable. The aim of this research isto test and analyze whether there is an influence between the ability to prepare financial reportsbased on SAK ETAP on performance and financial literacy as a moderating variable. The researchmethod uses quantitative methods, the SMEs population in Serang City was taken using purposivesampling, hypothesis testing used PLS. The finding that the ability to prepare financial reportspossessed by managers in Serang City affects performance, this is due to the intensive training andmentoring carried out by the cooperative, SMEs, industry and trade services but SMEs managershave not been able to prepare it. general financial reports with financial literacy awareness. Thisresearch concludes that the ability to prepare financial reports and financial literacy have a positiveinfluence on SMEs performance, while the ability to prepare financial reports mediated byfinancial literacy has no effect on financial literacy.
