In this study, production of biodiesel from palm oil using cockle shell wastes as catalyst was carried out using transesterification reaction. The objectives of this study are to analyze and characterize calcium oxide (CaO) from cockle shell wastes and to determine the catalytic activity of derived shell catalyst towards the percentage yield of biodiesel produced. The effect of methanol to oil ratio, reaction time and reaction temperature were investigated. The types of esters content in biodiesel and the functional group presence in catalyst were determined using FTIR and GC-MS analysis. The results showed that the optimum condition for cockle shell wastes achieved maximum yield of biodiesel (78.05%) is at reaction temperature 50°C within 1 hour with 9:1 methanol to oil ratio. Meanwhile for commercial CaO, the maximum yield is 73.95% at 60°C within 3 hours for 3:1 methanol to oil ratio. From the result obtained, this indicated that cockle shell wastes have potential to substitute commercial CaO as catalyst in transesterification reaction.

Waste from fishery sector such as seashells are widely used in construction and building materials in order to reduce waste quantity. This study investigates the utilization of cockle shell powder (CSP) as partial replacement for fine aggregates in producing cement brick (CB). Bricks specimen are designed with three different percentages of 5% (CSP5CB), 10% (CSP10CB) and 15% (CSP15CB) replacements including control cement brick (CCB). An analysis conduct in this study are included sieve and specific gravity for materials testing while compressive strength, density and water absorption are for harden specimens. A rectangular brick shape specimen with 200mm × 100mm × 100mm in volume were used then cured using tap water for 7 and 28 days. The result revealed that compressive strength for specimens containing CSP are higher compared to CCB specimens. Besides that, CSP brick given a higher density with 2381.25 kg/m3 and lower water absorption 0.31% contrast from control specimens. According to overall data collected, the optimum composition for CSP in cement brick was 5% which indicated higher compressive and lower water absorption. Thus, the incorporation of CSP as sand replacement in bricks could improve and enhance physical and mechanical developments of bricks with the increment of curing time.

Enhancing the cement strength through attaching chemical additive has been popular to meet the required condition for a particular well-cementing job. However, due to a low oil-price phenomenon, pouring and additive should be reconsidered because it can raise the cost and make the project become uneconomic. Another additive material in nanocomposite form will be introduced through this experimental study. The nanocomposite material consist of silica nanoparticle, known as “Nanosilica” and a palm-shell-waste, which is abundant in Indonesia. Before making a nanocomposite, the palm-shell should be burned to obtain a charcoal form, ground and sieved to attain a uniform size.   The study focuses on the two parameters, compressive strength and shear bond strength, which can reflect the strength of the cement. These values are obtained by performing a biaxial loading test to the cement sample. Various samples with different concentration of nanocomposite should be prepared and following the mixing, drying, and hardening process before the loading test is carried out. The result from the test shows a positive indication for compressive strength and shear bond strength values, according to the representative well cementing standards. Increasing the nanocomposite concentration on the cement will increase these values. Furthermore, an investigation on the temperature effect confirms that the sample with 700oC burning temperature have highest compressive-strength and shear-bond-strength values. This is a potential opportunity utilizing a waste-based material to produce another product with higher economic value.
