Abstract

Ferronickel slag is a byproduct of nickel ore smelting. Several efforts have been made to find alternative applications for ferronickel slag, such as the production of construction materials, cement, or geopolymers. It is reported that 38% is used for road construction, 48% is used for industrial cement mixtures, and the rest is used for fertilizers, geopolymers, and hydraulic techniques. Ferronickel slag still contains some valuable minerals such as silica, magnesium, nickel, iron, and several REEs (rare earth elements). One of the REEs, namely lanthanum, has many applications, including Ni-MH (nickel-metal hydride) batteries, phosphors for lamps, fluid-cracking catalysts for oil refining, LaNi5 for hydrogen gas storage, metal alloys for cast iron, steel and magnesium alloys, additives for glassware (for cameras), and lanthanum hexaboride ceramic. In connection with the slag, which contains impurities in strong silica compounds, it is necessary to carry out an alkaline fusion treatment. Alkaline fusion was carried out by varying the time from 0.5 to 4 hours and the ratio of the mass of slag to NaOH: 1:0.6, 1:1, 1:1.23, 1:1.47, and 1:1.84. The biggest decrease in SiO2 was in the 3-hour alkaline fusion time, from 48.347% to 27.3%, and in the mass ratio at 1:1.47, from 48.347% to 21.413%. This research aims to provide added value for ferronickel slag by extracting lanthanum by acid leaching using H2SO4 reagent by varying the time (5, 10, 30, 60, and 120 minutes), temperature (30, 60, and 90 °C), and concentration (1, 2, and 3 M). The results showed that the best leaching point was at 5 minutes, 30 °C, and 1 M, yielding a lanthanum extraction percentage of 38.082%.

Abstract

This research was conducted in Muara Nibung Village, Pandan District, Tapanuli Tengah Regency, North Sumatra Province with the aim of knowing the amount of investment, profits and the level of feasibility of fishing for a Bagan Tancap fisherman based on financial aspects of using investment analysis, income, profit, revenue cost (R/C), financial rate of return (FRR), and payback period of capital (PPC). The method used in this study is a survey method while the determination of respondents is carried out by a census. The data collection was carried out by observations, interviews and documentation directly with 37 people of Bagan Tancap fishermen. The results of the study show that the Bagan tancap in Muara Nibung has two categories of operating distance from the coast, including the Bagan dekat ±1 km and the Bagan jauh ±3 km, of course different investments, profit and business feasibility. For Bagan dekat ±1 km the total investment is (IDR 124,616,000.00), the profit received is (IDR 121,240,800.00/year), R/C (2.59), FRR (97.29), PPC (1.03). Whereas Bagan jauh ±3 km the total investment is (IDR 139,416,000.00), the profit received is (IDR 179,140,800.00/year), R/C (2.85), FRR (128.49), PPC (0.78). Based on the results of the calculation that the R/C is more than 1, the FRR is greater than the bank interest rate of 11%, and the PPC is getting smaller, meaning that the fishing business is profitable and feasible to continue.

Abstract

Striped Catfish (Pangasius sp) is a freshwater fish that has good prospects for development because it has important economic value, this is because the selling price is quite high and can be marketed in fresh and processed forms. Striped catfish in Riau Province has been developed by the community, especially in Kampar Regency. This research was conducted in Koto Masjid Village, Kampar Regency in November 2021. This study aims to determine the business feasibility and prospects for the development of striped catfish farming. This research uses survey method. Data analysis was carried out on aquaculture with a pond area of ​​1000 m2. Business analysis is carried out on investment, fixed capital, working capital and profits. Data analysis used to determine the financial feasibility of a business is Revenue Cost of Ratio (RCR), financial Rate of Return (FRR), and Payback Period of Capital (PPC). Respondents in this study were Striped Catfish cultivators, feed entrepreneurs, and hatcheries. The results showed that the catfish farming business was very feasible to be developed both in terms of profit, business feasibility and sustainability aspects. The prospect of developing this business is very good in terms of input, production process, and market demand. In addition, there is still land available for striped catfish cultivation, making it possible for business expansion

Abstract

The aim of this research was to investigate the impact of various types of plastic packaging on the physical characteristics, weight, sugar content, and shelf life of honey pineapple (Ananas Comosus (L.) Merr.). Additionally, this study aimed to evaluate the influence of Polypropylene (PP) and High Density Polyethylene (HDPE) plastic packaging on the sensory evaluation of honey pineapple fruit following storage. Employing a Completely Randomized Design (CRD) with three replications, treatments included no packaging, Polypropylene (PP) plastic packaging, and High Density Polyethylene (HDPE). Research parameters encompassed the physical and chemical properties of honey pineapple fruit, such as weight loss, color, aroma, texture, and sugar content.Findings revealed that honey pineapple subjected to treatment (P1) exhibited the lowest weight loss percentage (0.04%), contrasting with the highest weight loss observed in P0 (11.6%). ANOVA analysis of the scoring test indicated no significant differences in color, aroma, or texture. Honey pineapple fruit under treatment P2 demonstrated the lowest percentage of total sugar content compared to P0 and P1. Regarding physical appearance, honey pineapple fruit treated with P0 displayed the most pronounced change in aroma. According to the experimental assessment based on SNI 3166-2009, honey pineapple fruit without packaging failed to meet quality criteria, while those packaged in Polypropylene (PP) and High Density Polyethylene (HDPE) plastic met the quality standards for honey pineapple.
