Litsea glutinosa is known in the local community as medang lendir. It is spec…
Pyrazoline is an azole group compound with a pentacyclic ring containing two nitrogen atoms. Pyrazoline with various biological activities has an important role in organic chemistry because of its application as a medicinal substance. In this case the pyrazoline compound (E)-7-(4-methoxybenziliden-3-(4-methoxyphenil)-5-methyl-2-phenil-3,3a,4,5,6,7-hexahydro-2H-pyrazolo[4,3-c] pyridine, has been…
Natural of pyrazoline such as vitamins, alkaloids and pigments, but there are limited availability, till synthesis is required. analog of Pyrazoline have biological activity caused their substituents. Therefore, 4- (3- (2-chlorophenyl) -5- (2- methoxyphenyl) -4,5-dihydro-1H-pyrazol-1-yl) benzenesulfonamide (1,3,5-triaryl pyrazoline was synthesized 25) development by adding chlorophenyl, met…
Dye waste produced by industries contains dangerous and poison materials that could pollute the environment. In this study, hydroxyapatite calcium deficient will be used as medium of adsorption. This process will determine the isotherm models, thermodynamic, and adsorption kinetics models. The dye adsorption process was carried out at various temperatures and initial concentration of dye at…
Plastic is a type of packaging that is often used in everyday life, however, in general, the plastic used is synthetic plastic which takes a very long time to decompose. Bioplastic is an environmentally friendly plastic film made from organic materials so that it can decompose naturally with the help of microorganisms. This study aims to determine the effect of adding various durian seed fl…

Lycopene or what is often referred to as α-carotene is a bright red pigment that is found in fruits that are orange to red. Lycopene is a carotenoid antioxidant that is very powerful and needed by the body. The main source of lycopene that has not been optimally utilized is Palm Fatty Acid Destillate (PFAD), a byproduct of the palm oil processing industry. The reddish orange color of the P…
The characteristics of SBE and quicklime almost resemble sand, but have finer particles, therefore these two materials are used in this study as a substitute for some of the sand in brick making. The purpose of this study was to determine the effect of the variation in the addition of the amount of SBE and quicklime used in the making of the concrete blocks and the quality of the bricks mad…

The mixture of cooking oil and premium has not been widely utilized as a fuel for rose stoves. So far, a vast majority of people use kerosene in rose stoves, however the cost is very expensive. The purpose of this research was to find the alternative fuels in order to replace kerosene for rose stoves. To obtain the best fuel performance, the ratio used cooking oil and premium mixture varies…
Essential oils are volatile oils or flying oils which are generally liquid and are obtained from plant parts, roots, bark, stems, leaves, fruit, seeds or flowers by distillation. Plants that contain essential oils and have the potential to be developed are lemongrass and white ginger rhizome. The purpose of this study was to utilize natural local commodities in the form of lemongrass stalks…

E-waste as printer casing is plastic that resistant to chemicals, stable to heat, strength and gristly. One of the efforts to reduce e-waste is to utilize it as a brick for building materials. The purpose of this research is to use the casing of printer waste as substitute for some sand on the Production of bricks, to determine the influence of variation in the refined printer chasing on dr…
The influence of Spent Bleaching Earth (SBE) and carbonate lime variations on the quality of bricks is one alternative in order to find alternative variations to the quality of bricks. The characteristic of SBE and carbonate lime almost resemble sand, but have finer particles, therefore both of these materials were used in this research as a substitute for some sand in brick making. The pur…
Hand washing soap was a special liquid soap for washing hands to make it clean, fragrant, soft, and safe for the skin. During the Covid-19 pandemic, hand soap was needed to maintain cleanliness. This study aims to make hand soap with a variation in the addition of the amount of texapon and to compare it with the SNI 2588-2017 parameters. The variation in the number of texapon used was 5; 15…
Used paper is one of the potential sources of fiber which can be used as an alternative raw material for wood for making paper by recycling. This study aims to study the process of making recycled paper using a statistical process control (SPC) method, to determine the characteristics of the recycled paper produced, including moisture content (%), paper thickness (mm) and paper gramature (g…
