Efficiency energy and stream data mining on Wireless Sensor Networks (WSNs) are a very interesting issue to be discussed. Routing protocols technology and resource-aware can be done to improve energy efficiency. In this paper we try to merge routing protocol technology using routing Distance Vector and Resource-Aware (RA) framework on heterogeneity wireless sensor networks by combining sun-SPOT and Imote2 platform wireless sensor networks. RA perform resource monitoring process of the battery, memory and CPU load more optimally and efficiently. The process uses Light-Weight Clustering (LWC) and Light Weight Frequent Item (LWF). The results obtained that by adapting Resource-Aware in wireless sensor networks, the lifetime of wireless sensor improve up to ± 16.62%.

Penelitian ini dilakukan untuk mengevaluasi karakteristik kemampuan bentuk kawat jaring baja SS 304 dengan variabel ukuran mesh 5, 6, dan 8. Tujuannya adalah untuk menilai kesesuaian lembaran kawat jaring dengan bobot yang ringan terhadap logam lembaran monolitik material SS 304. Uji eksperimental dilakukan untuk menganalisis sifat tarik, kemampuan regang (stretchability), dan kemampuan penarikan dalam  (deep drawability) dari lembaran kawat jaring. Hasil penelitian ini menunjukkan bahwa spesimen kawat jaring SS 304 tanpa perlakuan panas menunjukkan perilaku getas dengan elongasi minimal. Namun, perlakuan anil pada suhu 1050^oC selama 30 menit secara signifikan meningkatkan keuletan dan mampu regang lembaran kawat jaring tetapi menurunkan kekuatan. Hal ini dapat dilihat dari peningkatan nilai regangan pada saat putus (ε) dan koefisien pengerasan regangan (n-value), serta penurunan nilai koefisien kekuatan (K-value). Dipelajari pula perbandingan perilaku mampu bentuk lembaran kawat jaring dan lembaran logam monolitik dengan komposisi yang identik. Secara umum lembaran kawat jaring menunjukkan sifat tarik, perilaku regangan, dan penarikan dalam yang berbeda dibandingkan lembaran monolitik. Perbedaan ini dapat dijelaskan dengan adanya area terbuka dan variasi ketebalan pada struktur kawat jaring. Sifat mampu bentuk lembaran kawat jaring meningkat dengan menurunnya persentase area terbuka. ...... This study aimed to evaluate the formability characteristics of SS 304 wire mesh with mesh sizes 5, 6, and 8, which will be used for the development of automotive components. The aim is to assess the suitability of a lightweight wire mesh sheet in relation to the monolithic sheet metal of SS 304 material. Experimental tests were conducted to analyze the tensile properties, stretchability, and deep drawability of the wire mesh sheets. The results showed that non-annealed SS 304 wire exhibited brittle behavior with minimal elongation. However, annealing treatment at a temperature of 1050°C for 30 minutes significantly improved the ductility and stretchability of the wire mesh sheets while reducing their strength. This can be observed from the increased elongation at fracture (ε) and strain hardening exponent (n value), as well as the decreased strength coefficient (K value). Comparisons were made between the formability behavior of wire mesh sheets and monolithic sheet metals with identical compositions. Overall, the wire mesh sheets displayed different tensile properties, stretching behavior, and deep drawing characteristics compared to monolithic sheets. These differences can be attributed to the presence of open areas and variations in thickness within the wire mesh structure. The formability of the wire mesh sheets improved with a decrease in the percentage of open area.

Plastik jenis PET yang banyak digunakan sebagai botol air mineral dapat didaur kembali sebagai agregat kasar bagi pembuatan beton ringan. Dalam penelitian ini, dilakukan uji pembebanan empat titik pada balok beton beragregat PET yang dikategorikan sebagai balok Bernoulli. Untuk mengetahui properti beton ringan, dilakukan uji modulus elastisitas, kuat tekan, kuat tarik dan rangkak. Hasil uji pembebanan empat titik dipresentasikan dalam hubungan momen - kelengkungan sebagai hasil dari aplikasi tiga pola penambahan pembebanan yang berbeda, yaitu dengan melihat besarnya perbedaan lendutan sebelum dan sesudah penambahan beban, penambahan beban setiap 45 menit dan penambahan beban setiap 24 jam. Pola pembebanan dengan melihat perbedaan lendutan dapat memperlihatkan adanya pengaruh rangkak pada hubungan momen ? kelengkungan. Sesuatu yang tidak muncul pada hubungan momen-kelengkungan hasil 2 pola pembebanan lainnya.

recycled back as coarse aggregate for making lightweight concrete. In this study, four points test loading is conducted on concrete beam using PET aggregate. The concrete beam itself is classified as Bernoulli beam. To find property of lightweight concrete, test for determining modulus of elasticity, compressive strength, tensile strength and creep were performed. Test results of beam due to four points loading are presented in relationship between moment - curvature as function of load increment. Three load increment patterns are applied on the beam. The first method of loading increment application depends to displacement limit value between 2 successive loadings, in the second method load is applied at every 45 minutes and in the third method load is applied at every 24 hours. Moment - curvature diagram resulting from the first method of loading application is influenced by creep. A phenomenon that can not be shown by the moment-curvature relation resulting from two others method of loading application.

Keberadaan atap pada rumah ataupun bangunan lainnya sangat penting mengingat fungsinya untuk melindungi seluruh ruangan yang ada di bawahnya terhadap pengaruh cuaca (panas, hujan, angin). Saat ini di dunia konstruksi kita mengenal material rangka atap kayu, baja konvensional atau berat dan rangka atap baja ringan. Studi ini berusaha mencoba mengeksplorasi manfaat sistem rangka atap baja ringan dibandingkan dengan cara konvensional, terutama terhadap biaya pertama (initial cost) sehingga keuntungan dari sistem rangka baja ringan dengan kayu konvensional sudah tidak dibahas lagi. Perhitungan terhadap biaya pertama (initial cost) bukan merupakan biaya perhitungan - mutlak - dari beberapa studi kasus yang ada melainkan untuk mendapatkan - trend - khusus dari jenis rangka atap baja ringan mana yang memberikan kemungkinan biaya pertama (initial cost) pembuatannya mengimbangi atau bahkan lebih murah daripada rangka atap kayu. Metodologi penelitian yang dipakai penulis adalah dengan studi kasus, dengan membandingkan kedua sistem rangka atap dalam hal ini menggunakan software Pryda Roof untuk menghitung kebutuhan material dari masing masing jenis rangka atap yang diteliti. Dalam studi ini akan dibahas beberapa jenis bentuk rangka atap dan membandingkannya dari segi metode, biaya, mutu, waktu dan keamanan dari kedua sistem rangka atap ini. Berdasarkan hasil penelitian, secara keseluruhan rangka atap baja ringan pryda lebih unggul daripada rangka atap kayu konvensional tetapi dari segi biaya rangka atap pryda lebih mahal daripda rangka atap kayu konvensional.

Roof or other construction is really important since its function to protect the whole chambers under it from the weather (hot, rain, wind). Today, in a construction world we are familiar with timber roof construction, conventional heavy steel roof construction, and light-weight steel roof construction. This study is trying to explore the advantage of the light-weight roof construction system in comparison with the conventional one, concerning to the initial cost so the profit of the light-weight roof construction and the conventional one will not be discussed anymore. The calculation through the initial cost is not an absolute cost calculation from some case studies, but it's only the way to get the special trend which one of this light-weight roof construction that will present the possibility of the manufacture initial cost causes balance or cheaper than the timber roof construction. The research method uses the case study by comparing these two roof construction system and using the Pryda Roof software and SAP to calculate the needs of material of each roof construction concerned. In this study will be discussed some kind of roof construction system with the covering of the roof is ceramic roof-tile, and compared these two roof construction system to the cost, quality and time. These on the research, pryda light steel system is better than conventional timber roof but the cost is higger.
