NiO/silica-rich zeolite catalysts were used for coconut oil hydrocracking. The catalyst was prepared with a mixture of Na2SiO3, Al(OH)3, NaOH, and quaternary ammonium surfactants. The surfactant was varied of types like as tetrapropylammonium bromide (TPAB) and cetyltrimethylammonium bromide (CTAB). The acidity of the silica-rich sodalite zeolites enhances with the increase in nickel oxide added through a wet impregnation. The hydrocracking process was carried out by a semi-batch method. Liquid products were analyzed using GC-MS. The results showed that the addition of surfactants increased the catalyst surface area and acidity. Meanwhile, the presence of nickel oxide increases the acidity of the catalyst. The hydrocracking results showed an increase in gas products when the surface area was high, i.e., 23.781% in silica-rich sodalite zeolite without template (Z), 32.68% in silica-rich sodalite zeolite with tetrapropylammonium (ZTPA), and 39.673% in silica-rich sodalite zeolite with cetyltrimethylammonium (ZCTA). The presence of NiO increased the liquid product and the selectivity of the bioavtur fraction (C10-C15), where the highest percentage of liquid product was 60.07% at NiO/ZTPA.

Silica-rich sodalite zeolite has been synthesized by ultrasound treatment and hydrothermal temperature variation. This study aimed to determine the effect of ultrasound treatment and hydrothermal temperature variations on the crystallinity, hydrophobicity, and structural properties of silica-rich sodalite zeolite. The synthesis was conducted by reacting a sodium aluminate and sodium silicate solution by varying Si/Al ratios of 20, 30, 40, 60, 80, and 90. The next step was to characterize the product. The product with the best crystallinity was used as a reference to determine the effect of ultrasound and hydrothermal temperature. The reaction gel was treated with and without ultrasound and hydrothermal using autoclave at 100, 150, and 200°C for 24 hours. The last step was the product characterization using XRD, FTIR, and GSA. The XRD showed similarity peaks at 2θ = 14.058°; 24.41°; 31.73°; 34.75°; 42.88°. The best crystallinity was silica-rich sodalite zeolite with a Si/Al ratio of 30. Meanwhile, silica-rich sodalite zeolite peaks were obtained at 2θ = 14.16°, 24.66°, 31.99°, 35.13°, and 43.39° by ultrasound treatment and hydrothermal temperature variation (100, 150, and 200°C). Ultrasound treatment revealed the presence of other peaks besides sodalite at 2θ = 19.05° and 27°, where these peaks were referred to as SAPO-56. In conclusion, the degree of crystallinity increased with increasing temperature, decreasing Si-OH/Si-O-Si showed increased hydrophobic properties. Increasing the hydrothermal temperature of 150 and 200°C with and without ultrasound treatment increased the surface area significantly to 114.137 m2/g and 160.717 m2/g, and the pore volume of sodalite with a Si/Al ratio of 30 to 0.318 cc/g and 0.274 cc/g.

Chitosan is natural polysaccharides which is nontoxic, biodegradable, and biocompatible and have many advantages in various kinds of fields including health, food, agriculture, and industry. Chitosan usually take long time to extract by conventional method for deacetylation process of chitin. Raw material for chitosan can be found in shrimp shell waste. Chitosan manufactures usually need high temperatures and chemicals in large quantities and it takes much time and consumes a lot of energy where will give bad effect to the environment. Recently microwave irradiation as nonconventional energy sources is widely used in chemical reactions. To reduce the impact of environmental pollution due to excessive use of chemical treatment, the objective of this work is processing chitosan under microwave irradiation. Expected production of chitosan with the same mass requires fewer chemicals than conventional heating. In particular, the study will examine the effect of making the chitosan and adding chemicals, reaction time and operating temperature and degree of deacetylation in chitosan with conventional heating methods that the results will be compared using a microwave. In this research will be developed to the design and fabrication of prototype scale extractor for manufacturing chitosan from shrimp shell waste after optimum results obtained from the research laboratory scale. From the research we can conclude that microwave will speed up reaction time. FTIR also showed functional group of chitosan formed from microwave irradiation have same results. Keywords: chitosan, shrimp shells, microwave

Wakaf disputes are found in many places in Indonesia. One of thereasons is that there are many wakaf land that has not been registered(certified) to the authorized official. So it caused that the wakaf landstill do not have certainty and the protection of clear law. This issueencourages legal experts to provide solutions to uncertified wakafland. The solution to provide protection for the wakaf land is theemergence of isbat wakaf as a solution to solve the problems of wakafland that has not been certified.Isbat wakaf aims to provide law protection of wakaf land, justifyingprevious law acts such as waqif, nadzir, and managers, and used asevidence in the certification of waqf objects, giving full advocacy tothe disputed waqf land or legally problematic. Isbat wakaf is theauthority of the Religious Court, this is based on Law no. 14 of 1970amended by Law no. 4 of 2004 on Judicial Power and Law no. 3 of2006 on Amendment to Law no. 7 of 1989 on Religious Courts.

Mediation is one of the means and efforts to resolve disputes that occur between husband and wife in a peaceful manner that is appropriate, effective, and can open wider access to the parties to obtain a satisfactory and just settlement. In response, the Supreme Court release the regulation of supreme court governing mediation procedure in proceedings in court. Beginning with the SEMA (Surat Edaran Mahkamah Agung) or Supreme Court Circular Number 1 year 2002 on the Empowerment of the First Tribunal Applying the Peace Institution, instructed all the judges who tried the case, in order to sincerely seek peace among the litigants. However, because some basic matters have not been explicitly stipulated in the SEMA, the Supreme Court issued Perma (Regulation of the Supreme Court) RI Number 2 Year 2003 on Mediation Procedure in Court, which was then revised and refined by Perma Number 1 Year 2008, which further reinforce the obligation to pursue mediation procedures related to litigation in court. And its peak on February 4, 2016 Supreme Court renewed by ratifying Perma Number 1 Year 2016 on Mediation Procedure. This paper discusses about how the implementation of this Perma, what are the supporting and inhibiting factors in the success of mediation and the extent of its effectiveness in the settlement of divorce cases in the Religious Court of Palu.

Airplanes are a very fast and time efficient means of transportation. In Indonesia itself, because the country is an archipelago and has a tropical climate, rainwater and seawater are the main problems in the aviation world, this is evidenced by the corrosion that occurs in every aircraft maintenance. Factors that cause corrosion and corrosion rate are acidity, environmental conditions, and materials used. The material that is often used in aircraft is 2024 T-3 aluminum material which is strong, lightweight, and also resistant to corrosion, but because 2024 T-3 aluminum has several mixtures of other materials such as iron, copper, and copper,other materials, then aluminum can also be exposed to corrosion and corrosion rates. Corrosion and corrosion rate can be determined using the weight loss method which is used to measure the rate of corrosion that occurs, it is proven in 72 hours the material has experienced a corrosion rate of 0.002 mpy and the corrosion rate continues to increase every day, and to see the corrosion that occurs on the material used micro photos to see the type of corrosion. But the weight loss method is not very accurate because the weight loss that occurs from the material is the result of abrasion when sanded. In addition, seawater is the biggest influence on the corrosion rate problem when compared to rainwater.
