Coarse aggregates commonly used in concrete are coarse natural aggregates, which are broken stones or gravel. Continuous rock exploration can cause environmental damage or even more severe ecosystem damage. Therefore it is necessary to substitute an alternative aggregate. Indonesia has the second largest oil palm plantation (Elaeis guineensis Jacq) in the world after Malaysia. Plantations are renewable resources, so palm oil is also potential to be used as an alternative to diesel fuel. Palm kernel shells are palm oil industry wastes which are generally underutilized. Palm kernel shells can be used as an alternative to coarse aggregate, because oil palm shells have the advantage of being hard, tough and good durability due to the high content of lignin and silica dioxide (SiO2), such as hard wood, but low cellulose content so it is not easy rot. The strength of the palm oil shell is quite good. In addition, the aggregate gradation also fulfills the requirements without a breakdown process, which has a thickness of 2-4 mm and a maximum width of 15 mm. The volume of oil palm shells is + 600 kg/m3, so it will produce significant light weight concrete. The concrete studied was concrete with a coarse aggregate of tenera palm kernel shells, with fine aggregates of natural sand, and a Portland Composite Cement (PCC), but the PCC content was reduced and replaced by FA which varied from 0%, 5%, 10 %, 15%, 20 and 25%. Concrete also added superplasticizer (SP). SP is used to reduce water use, because the shell absorbs water. SP levels also vary, namely 0%, 1%, and 1.2%. The weight of the volume of concrete with various levels of fly ash and SP is 1700-1800 kg/m3, so it can be classified as lightweight concrete. Increased FA levels will increase compressive strength, but only up to 10%, after which the strength decreases. Compressive strength of specimens with SP 0% and FA 10% is 17.92 MPa, for SP levels of 1% and FA 10% is 22.15 MPa, while for SP levels of 1.2% and FA 10% is 19.35 MPa . So that it can be concluded that the palm shell as bio-material (renewable resources) can be used as a substitute for natural coarse aggregates. The optimum fly ash level is 10%, and to reduce water use SP 1%. The use of oil palm shells as a substitute for gravel means reducing the waste of the palm oil industry, while reducing rock exposures. In addition, in Indonesia there are many areas where there are no rock sources while oil palm plantations are quite extensive.

Menstruation is a characteristic of puberty in adolescent girls. Adolescent girls often have complaints of premenstrual syndrome (PMS) that is characterized by a collection of physical and psychological symptoms which occur in 7 to 10 days before menstruation. Studies have shown that there are several ways to relieve PMS. Therefore, the main objective of this study was to analyze isoflavone, nutrients intake, and stress level to Premenstrual Syndromes in adolescent girls in Bogor, West Java. The study was conducted on 100 girls aged 15-16 years at two high schools in Bogor. This present study showed that the majority of adolescent girls had PMS which most of them suffered severe symptoms. Results showed that the isoflavone and nutrients intake were not significantly associated with premenstrual syndromes. Stress level had a positive correlation to the PMS but did not seem to be a risk factor to PMS. Howefer, this implies that controling stress is important so that young women can avoid severe premenstrual syndromes.

Publisher : Universitas Pakuan

One of the studies that recently attracted the attention of physicists is research on ferroelectric material because this material is very promising for the development of new generation devices in connection with the unique properties it has. Ferroelectric materials, especially those based on a mixture of lithium tantalite (LiTaO3), are expected to be applied to the infrared sensor. Lithium tantalate (LiTaO3) is a ferroelectric material that is unique in terms of pyroelectric and piezoelectric properties that are integrated with good mechanical and chemical stability. Therefore LiTaO3 is often used for several applications such as electro-optical modulators and pyroelectric detectors. LiTaO3 is a non-hygroscopic crystal, colorless, soluble in water, has a high transmission rate and does not easily damage its optical properties. LiTaO3 is a material that has a high dielectric constant and a high load storage capacity. This research has succeeded in determining the band gap energy of the LiTaO3 film in the rubidium chamber obtained in the range of values 2.02-2.98 eV as shown in figure 4. The LiTaO3 film after the annealing process at a temperature of 650 oC, has the highest band gap energy of 2.98 eV. Large energy is needed on the electrons to be excited from the valence band to the conduction band. Whereas in the LiTaO3 film after an annealing process of 800 oC, the band gap energy obtained is 2.02 eV. This makes it easier for electrons to be excited from the valence band to the conduction band because the energy needed is not too large.

User satisfaction is a major factor in designing a product. Technically it can be realized explicitly how the product is designed according to the needs of its users. There are other factors that influence the success of the product, the psychological value of the user who can implicitly become a parameter in product design. But the thing that becomes a constraint is how to translate these psychological factors into the parameters of product design. Kansei Engineering (KE) is one approach in product design that involves the user's psychological side and how to translate the cognitive aspects of the user into the product of the design proposal. The KE methods, the one discussed in this study, is Kansei Engineering Type 1 (KEPack), which involves several multivariate analyzes. The conclusion of this research is how KE in designing a product, not only industrial product, but KE can be involved in matters related to Human Computer Interaction, especially interface design. Keywords: Product Development, Kansei Engineering, Kansei Engineering Type 1 (KEPack)
