USULAN RANCANGAN ULANG HELM SNI YANG ERGONOMIS
No full textHelm merupakan salah satu perlindungan wajib yang
harus dikenakan pengendara kendaraan roda dua. Saat ini
peraturan mengenai penggunaan helm telah diatur oleh
pemerintah melalui peraturan SNI 1811:2007. Walaupun
demikian, masalah ketidaknyamanan dalam menggunakan
helm tetap terjadi, baik dari segi ukuran, pandangan,
maupun berat helm. Usulan perancangan diharapkan dapat
mengatasi masalah ketidaknyaman yang dialami pengguna
helm tersebut. Perlindungan yang diberikan helm
terutama saat terjadi kecelakaan pun tetap harus
diperhatikan.
Analisis yang dilakukan adalah analisis data
anthropometri dan metode rasional. Analisis
anthropometri digunakan untuk merancang ukuran helm
yang sesuai dengan ukuran kepala masyarakat. Metode
rasional digunakan untuk membangkitkan alternatifalternatif
sehingga helm yang dibuat memenuhi kriteria
yang diberikan oleh pengguna helm maupun aturan yang
berlaku.
Hasil yang diperoleh adalah usulan rancangan helm
dengan tiga ukuran yaitu S, M dan L. Selain itu juga,
didapatkan tebal bantalan pelindung dan bentuk tali
pelindung dagu yang sesuai dengan sifat dari pengendara
kendaraan roda dua saat ini
Harvesting Techniques of Jatropha Curcas, L., and Economic Sustainability
No full textJatropha cultivation could represent an interesting source of income in developing countries where the plant may find environmental conditions adapt for its growth. The oil-containing seeds of Jatropha curcas L., could be a possible feedstock for biodiesel production. However, the harvesting of this plant presents several problems due to the presence of fruits that are in bunches and that do not ripen simultaneously: for these reasons, mechanical solutions aimed at facilitating harvesting operations are still limited. In fact, the main cost of Jatropha curcas L cultivation is the labor cost for fruit collection. Other costs include the mechanical equipment and the raw materials usage costs. Three different harvesting techniques, classified according to the level of mechanization, have been analyzed: the manual harvesting system, fully mechanical harvesting, and semi-mechanical harvesting systems. Based on data collected in harvesting field test carried out in Cuba, the harvesting cost for Jatropha fruit is calculated in order to identify the best practice among the three different harvesting systems. At the present, the harvesting of Jatropha fruits is mainly based on manual operations. This practice results very strenuous and time-consuming. The paper will compare the mentioned three harvesting methods and their economic sustainability. Assessing the economic performances of different harvesting systems may contribute to the scientific literature towards the introduction of innovations useful to spread the Jatropha cultivation

Graf Garis dari Graf Helm dan Graf Helm Tertutup
No full textABSTRAK
Teori graf merupakan salah satu cabang ilmu matematika yang banyak digunakan, karena teori-teorinya dapat diterapkan pada cabang-cabang ilmu matematika yang lain atau untuk memecahkan masalah dalam kehidupan sehari-hari. Salah satu pokok bahasan dalam teori graf yang menarik adalah graf garis.
Graf G adalah pasangan himpunan (V, E) dengan V adalah himpunan tidak kosong dan berhingga dari obyek-obyek yang disebut sebagai titik dan E adalah himpunan (mungkin kosong) pasangan tak berurutan dari titik-titik berbeda di G yang disebut sebagai sisi. Graf G dengan V(G) adalah himpunan titik dan E(G) adalah himpunan sisi. Graf garis L(G) adalah graf dengan V(L(G))= E(G). Titik di L(G) akan terhubung langsung jika dan hanya jika sisi yang bersesuaian terhubung langsung di G.
Pada penelitian ini dibahas mengenai graf garis dari graf helm dengan anting- anting maksimal satu dengan order n ≥ 3 dan graf garis dari graf helm tertutup dengan anting-anting maksimal satu dengan order n ≥ 3 dengan n bilangan asli.
Berdasarkan hasil pembahasan dapat diperoleh kesimpulan bahwa bentuk umum untuk graf garis dari graf helm dengan order n ≥ 3 adalah (H n ) 3n, n 2 +11n , dimana graf garis dari graf helm mempunyai order 3n dan sisi sebanyak n + 11n . Sedangkan bentuk 2 umum untuk graf garis dari graf helm tertutup dengan order n ≥ 3 adalah ∧ L(H n ) 4 n, n 2 +17 n dimana graf garis dari graf helm tertutup mempunyai order 4n n 2 + 17n dan sisi sebanyak.
ABSTRACT
Graph theory is a branch of mathematics that is widely used, because of its theories can be applied to other mathematics branches or to solve problems in daily life. One subject of interest in graph theory is line graph.
Graph G is the set of pairs (V, E) with V is not empty and finite set of objects called vertices and E is the set (possibly empty) Unordered pair of distinct points in G is called side. Graph G with V (G) is the set point and E (G) is the set side. Line graph L (G) is a graph with V (L (G)) = E (G). Point in L (G) will be connected directly if and only if the corresponding connected directly in G.
In this study discussed about line graph of helmet graph with maximum earrings are one with order n ≥ 3 and line graph of closed helmet graph with maximum earrings are one with order n ≥ 3 with n is original numbers.
Based on the results of discussion, it can be concluded that the general shape of the line graph of helmet graph with order n ≥ 3 is L(H n ) 3n, n 2 +11n in which the line graph of helmet graph has order 3n and side n + 11n . While the general shape of the line 2 graph of closed helmet graph with order n ≥ 3 is ∧ L(H n ) 4 n, n 2 +17 n in which the line graph of closed helmet graph has order 4n and side n12 + 17n
A Dialogic Model for Telecollaboration
No full textIn language learning contexts, telecollaboration is understood to be internet-based intercultural exchange between people of different cultural/national backgrounds set up in an institutional context with the aim of developing both language skills and intercultural communicative competence. Generally students interact with one another on 'safe' topics and subsequently reflect on and discuss their interactions with teachers and peers. This paper presents a dialogic model of telecollaboration which breaks from this tradition as it entails interaction on topics which are seen as divisive through dialogue in groups led by trained facilitators, the Soliya Connect Program (SCP). The differences between this model of telecollaboration and traditional models are illustrated, and then the author presents the results of a survey study which looks at participants' evaluation of this program, what they perceive to be the role of the facilitators and their personal learning outcomes.Nell'apprendimento linguistico, 'telecollaboration' significa scambio interculturale online tra persone di diverse culture, organizzato a livello istituzionale, con l'obiettivo di sviluppare sia competenze linguistiche che interculturali attraverso attività strutturate. Solitamente, partecipanti discutono su argomenti 'sicuri' e poi riflettono sulle interazioni in classe con il docente. Questo articolo presenta un nuovo modello di telecollaboration, Soliya Connect Program, che si differenzia da questa tradizione in quanto partecipanti discutono argomenti contenziosi sotto la guida di facilitatori esperti. Vengono illustrate le differenze tra questi diversi modelli di telecollaboration e in seguito sono presentati i risultati di uno studio che indaga la valutazione di questo progetto da parte dei partecipanti, il ruolo dei facilitatori e i risultati di apprendimento percepiti dai partecipanti.En contextos de aprendizaje de idiomas, telecolaboración se entiende como el intercambio intercultural, facilitado vía Internet, entre las personas de diferentes orígenes culturales / nacionales. La interacción es construida en un contexto institucional con el objetivo de desarrollar tanto las habilidades lingüísticas como las competencias comunicativas e interculturales. En general, los estudiantes interactúan entre sí sobre temas "seguros" y, posteriormente, reflexionan y discuten sobre sus interacciones con los profesores y compañeros. En este trabajo se presenta un modelo dialógico de telecolaboración que rompe con esta tradición, ya que implica la interacción sobre temas que se consideran de división o conflictivos, a través del diálogo en grupos dirigidos por mediadores capacitados (dentro del Programa Connect Soliya). Se ilustran las diferencias entre este modelo de telecolaboración y los modelos tradicionales. La autora presenta los resultados de un estudio de investigación que analiza la evaluación de los participantes de este programa, como perciben el papel de los mediadores y los resultados personales de aprendizaje
