Published: March 2024

In Indonesia, land registration is promulgated in articles 19 of UUPA. To follow up such article, then PP No 10 of 1961 is established. Both regulations require negative system within land registration. This becomes one of the shortcomings of PP No 10 of 1961 which is then completed by PP No 24 of 1997. PP No 24 of 1997 itself adheres to negative system with positive system tendency.

Negative system in the land registration means that information or official statements described within land certificate (land book) is absolutely could be changed. Hence, everyone deserves or has a chance to file a lawsuit to the court as long as he/she is able to prove his/her legal right of land. Such a lawsuit can only be submitted within period of 5 years after the certificate published.

As for positive system tendency indicate the active role of relevant official in the application of land registration. Such official has to examine the land record carefully. Hence, it is land registration requires long duration to publish (30 days for systematic way and 60 days for sporadic way) in order to give everyone a chance to submit a protest or objection.This policy is established to prevent error or mistake as well as to gain the conformity between land certificate (land book) and the physics of land.

Furthermore, it is for the holder of certificate (either private person or legal entity) couldnâ€™t be charged after 5 years of legally possessing such certificate as long as he/she obtain it on the basis of good faith as well as real occupation principles (article 32 (2) PP No 24 of 1997). It indicates that such article adopts the concept of â€œRechtsverwerkingâ€ (Waiver of Right) established in Adat law as one of the causes of losing landâ€™s right; it is called â€œrechtsverwerkingâ€ if someone or the holder of land right do not within long term exploit the land and it is occupied by other party through transfer of right which based on good faith.

Sea transport is preferred because it is safe and economical in countries in the regions that dominate world trade. Approximately 86% of the developing and increasing trade volume is provided by sea transportation. Ports, which are an important pillar of international trade, take an active place in the transportation network for these reasons. In our country, an increase has been observed in the studies on the design of coastal port structures in the last 15 years. In the design of coastal structures, technical approaches and durability are at the forefront, while recently the continuity of the performance of the structures has been taken as a basis. They are exposed to static and dynamic loads throughout their service life. In order to encounter minimum damage due to earthquake effects, an analysis that reflects the behavior under static and dynamic loads and the parameters must be determined correctly. For this purpose, parameter changes were investigated to examine the dynamic behavior of a scaffolding structure. Piles diameters of 600, 800 and 1000 mm and placement spacing of 4D and 8D were considered variable. Analyzes were carried out with Sap 2000, a finite element program. The capacity of the building was determined with pushover analysis and its dynamic performance was evaluated with time history analysis.

In this study investigated the bending moment resistance of L-type doweled joints reinforced with glass-fiber-reinforced polymer woven fabrics (GFRPWF) and basalt-fiber-reinforced polymer woven fabrics (BFRPWF). Dowels produced from Scots pine, oak, beech and chestnut wood were used in the doweled joints. While the GFRPWF and BFRPWF were fixed with epoxy adhesive, the dowels were fixed with polyvinyl acetate (PVAc-D3/D4) glue. Test were carried out to determine the bending moment resistance of doweled joints. Experimental results showed that joints connected with oak dowel has been the highest bending moment resistance, and the joints of Scots pine dowel has been the weakest bending moment resistance. The bending moment resistance of oak dowel was approximately 23%, 33%, and 61% higher than for joints constructed with beech, Chestnut and Scots pine, respectively. The bending moment resistance value reinforced with the BFRPWF (55.62 N.m), and the lowest was in unreinforced joints (32.06 N.m). The mean bending moment resistance of reinforced joints (GFRPWF, BFRPWF) was 31% and 74% higher than unreinforced samples (control), respectively. In general, it has been found that the bending moment resistance of doweled joints is influenced by wooden dowel species and FRP types.
Extraction of alumina from fly ash by pyro-hydro metallurgical routes: A review
Authors: Rahul Mandal  , Manaranjan Mohanta
Published: March 2024

Fly ash is a resulting by-product formed due to the burning of pulverized coal on a steam-generating plant. Fly ash mainly contains alumina and silica, hence it can be an excellent secondary source for alumina. Today only 30% of global fly ash can be reused commercially, the remaining was dumped. This causes waste of resources and environmental pollution too. The alumina in the fly ash was in the form mullite phase which is a stable phase so decomposition of this phase is difficult. The mullite phase can be disilicated by calcination, roasting, etc which were pyro-metallurgical routes. Alumina can be extracted as aluminum hydroxide and other unstable forms from fly ash by hydrometallurgical routes. This process requires a huge amount of energy for reaction which is a major drawback of this process. Till now industrial extraction of alumina from fly ash cannot be feasible. Different researchers and scholars did various works to overcome this difficulty. This paper presents a review for extraction of alumina via these routes. It starts with different concepts used in extraction of alumina from fly ash. The middle portion presents the survey of work done by different scholars. The work finally concludes with future possibilties.

This study examined predictive validity of mathematics basic education certificate examination as correlate of mathematics geometry achievement among SS 2 students in Delta State. Two research questions and null hypotheses guided the study and Correlational research design was employed. The population of the study consisted of 105, 848 students who sat for BECE Mathematics in 2022 and SS 11 students in year 2024 in Delta State. The sample size of the study was 480 while the instruments used for this study was mathematics BECE scores and Geometry Achievement test (GAT). The internal consistency of the GAT yielded an index of 0.62. The Cronbach alpha method of estimating reliability was employed to obtain the reliability index of 0.84 for the mathematics BECE Proforma. The Pearson’s Product Moment Correlation Coefficient of Determination was used to answer the research questions while regression and fisher-z statistics were used to test the hypotheses at 0.05 level of significance. Based on this finding it was concluded that BECE Mathematics is a predictor of mathematics geometry achievement. However, the magnitude of relationship and the percentage of prediction of mathematics geometry achievement from BECE Mathematics performance were very low and weak. Based on the findings it was recommended among others that BECE Mathematics scheme, contents and curriculum should be reviewed in conformity with mathematics geometry to enhance its predictive validity, BECE that are conducted by NECO should be compulsorily used by all schools to ensure uniformity.

The capital market can play two very crucial roles in the country's economy, namely the role of economy and finance. For these two roles, some parties act as investors and as issuers. Seeing the existence of parties as investors, of course, there will be hope to profit, where the size of the return obtained depends on the company's stock price. However, the company's stock price continues to change every period because of influencing factors such as return on assets (ROA), debt on equity ratio (DER), current ratio (CR), and so on. In previous studies, these factors have not provided consistent answers on whether they affect stock prices. Therefore, to find out the actual results, this research was conducted. The object used is a company indexed in JII70. The selection of this object is due to the lack of research using Sharia objects. JII is a type of index in which there are 70 types of Sharia stocks with high liquidity listed on the IDX, Panel regression analysis is the analysis method applied in this study, where the study results show that ROA can significantly positively influence the stock price. In contrast, DER and CR cannot substantially affect the stock price
