A Quantitative Assessment of Price and Income Effects on Cooking Oil Demand
Get PDFCooking oil is a vital household commodity in Indonesia, yet its demand faces challenges from rising prices, limited availability, varying income levels, and shifting market preferences. These factors influence consumption patterns, particularly in rural areas where economic and market conditions differ from urban settings. This study aims to examine household characteristics, explore the nature of cooking oil demand, and identify factors influencing this demand in Pematang Tebih Village, Ujungbatu Subdistrict, Rokan Hulu Regency, Riau Province. Using a survey method, data were collected from 86 households across five hamlets, selected via simple random sampling. Descriptive analysis outlined household profiles and consumption patterns, while multiple linear regression analysis determined key influencing factors. Findings reveal that households, with an average age of 32 to 36 years and three family members, earn approximately 5,701,163 Indonesian Rupiah monthly. Most prefer packaged cooking oil priced between 15,000 and 17,000 Indonesian Rupiah per liter, with Minyakita as the dominant brand, consuming up to 4 liters monthly. Key factors affecting demand include prices of palm, bulk, and coconut cooking oils, wheat flour price, population income, and population size, explaining 85.1 percent of demand variation. In conclusion, these insights highlight the need for stable pricing and supply strategies to enhance affordability and food security in rural communities
Evaluasi Blind Drilling Untuk Mengatasi Lost Circulation Di Sumur “x” Dan lapangan “y”
No full textThe phenomenon of lost circulation, defined as the entry of drilling mud into the excavated structure, leading to a reduction in the quality of the mud flow, is a subject of concern. To address this issue, a comprehensive analysis is necessary to identify the underlying cause. This analysis involves the calculation and subsequent analysis of various parameters, including formation pressure, formation fracturing pressure, mud hydrostatic pressure, BHCP, and ECD. The objective is to determine the root cause of the lost circulation. The calculations and analysis reveal that the primary cause of lost circulation in well "x" of field "y" is naturally formed fractures (natural fracture) and a low formation pressure gradient. Subsequently, the hydraulic factor evaluation is conducted through a re design of the hydrostatic pressure calculation and a re-design of the bottom hole circulating pressure (BHCP). Concurrently, the mechanical factor evaluation is performed via ROP, RPM, WOB, and torque analysis to ascertain the presence of indications of pinched pipes during the blind drilling method. The blind drilling method was employed, resulting in the acquisition of the following parameters: a hydrostatic pressure value of 1675.39 psi, a mud weight (MW) of 9.6 ppg, a bottom hole circulating pressure (BHCP) of 1335.34 psi, and a Pump P of 419,586 psi. The ROP was measured at 130.0 meters per hour, the RPM was recorded at 70, the WOB was determined to be 10 kilograms, and the torque per bit diameter was established at 7.5 inches. These findings suggest that the indication of a pinched pipe is attributable to the decreasing ROP value. This evaluation is conducted to prevent lost circulation and to address issues related to mud loss during drilling operations
Uji Pengaruh Penambahan Nanosilika Pada Lumpur Water Base Mud Terhadap Rheology Dan Filtration Loss Lumpur Pemboran
No full textThe key to the success of drilling operation completion lies in the drilling mud that is carefully selected and designed. The characteristics of the drilling mud, particularly its rheological properties, must always be controlled in order to successfully carry out its tasks. Silica nanoparticles are one of the most commonly used additives to form nanofluids due to their ability to reduce water invasion in shale and control rheology and filtration. This study aims to observe the effect of adding nanosilica additives on the rheology of drilling mud, namely: density, plastic viscosity, yield point, gel strength, filtration loss, and mud cake. This study used two particle sizes of nanosilica, namely 8.6 nm (NS I) and 20 nm (NS II), as well as two variations of nanosilica concentrations, namely 0.13% and 0.20%. The results of the study indicate that the addition of nanosilica additives to water-based drilling mud improves rheological values and reduces filtration loss. The 8.6 nm silica nanoparticle size had a greater effect on improving the rheology of the mud compared to the 20 nm size. Meanwhile, the 20 nm nanosilica was more effective in reducing filtration loss. For the 0.20% nanosilica concentration, the increase in rheology was greater than at the 0.13% concentration. This rheological increase remained within the API standard range. The 0.20% concentration was also more effective in reducing filtration loss, and the mud cake thickness was more optimal, resulting in lower filtrate volume and producing a mud cake within the API standard range
Pertanggungjawaban Kerugian Kehilangan Sepeda Motor Yang Parkir Di Luar Mall Ska Pekanbaru
No full textParking is a transportation need for vehicles to stop temporarily or for a long time, then the owner leaves the vehicle to do activities, such as on the side of the road, parking buildings, or shopping centers, and parking lots provided. The development of transportation in the current era is one of the problems that must be faced, the development of this vehicle also affects the safety and security of the vehicle owner. Responsibility for losses due to loss of motorbikes parked outside the SKA Mall Pekanbaru, the author formulates two main problems, namely, first, what is the form of legal relationship between the owner of the motorbike and the manager of the parking lot outside the SKA Mall Pekanbaru, second, how is the responsibility of the parking manager for compensation for losses of motorbikes lost in the parking lot outside the SKA Mall Pekanbaru. This study aims to determine the form of legal relationship between vehicle owners or parking service users with parking managers or business actors, and aims to determine the responsibility for compensation for lost motorcycles in the parking lot outside the SKA Pekanbaru Mall. The approach to this study is a qualitative descriptive approach, with the population in this study being parking managers and parking users outside the SKA Pekanbaru Mall. The results of the study concluded that the legal relationship related to consumers and parking business actors is actually more regulated in the realm of Civil law in this case the goods deposit agreement and the Consumer Protection Law occurs because of the clause that applies unilaterally in this case if there is a loss to the parking consumer. The responsibility of the parking manager is only limited to finding and helping to report. Based on the legal relationship that occurs between consumers and parking business actors arising from the deposit agreement relationship and the relationship that occurs because of the consumer relationship that the deposit agreement gives rise to liability in this case to compensate for losses to parking service users or parking consumers
Analisis Dampak Penambahan Additive Cmc Eceng Gondok Terhadap Filtration Loss Dan Rheology Lumpur Pemboran
No full textThe main objective in oil and gas drilling operations is how the drilling can reach the planned final depth without any errors. This is related to common problems encountered in drilling mud, especially the lack of mud viscosity, which causes the inability of the mud to lift cuttings and the loss of fluid into the rock known as (filtration loss). The additive currently used in the oil industry for filtration loss is carboxymethyl cellulose (CMC). Mud that uses a basic mixture of additives in the form of CMC is useful for binding water and increasing viscosity. In this study, the focus is on producing carboxymethyl cellulose from water hyacinth, a wild weed that grows quickly in water and is very problematic. First of all, the cellulose compound found in water hyacinth needs to be isolated so as not to interfere with CMC production. There are two main reactions to convert cellulose into CMC: the first procedure is alkalization and the second reaction is followed by carboxymethylation. According to (Aini & Kuswytasari, 2013) dry water hyacinth has a chemical content in the form of cellulose 64.51%; pentose 15.61%, lignin 7.69%, silica 5.56% and ash 12%. The rheology of drilling mud that must be controlled in a drilling operation, whether oil and gas or geothermal, is viscosity, plastic viscosity, yield point, and gel strength. From the results of filtration loss and rheology research using CMC water hyacinth with concentrations of 2, 4, 6, 8. The density 8.60 - 8.65 ppg , viscosity values obtained were 45.11 - 49.43 s / quart, plastic viscosity 10 - 28 cp, yield point 29 - 41 lb / 100ft ^ 2, gel strength 0.4923 - 0.6723 lb / 100ft ^ 2, filtration loss 9.2 - 6.8 ml / 30 minutes, mud cake 0.30 - 0.79 mm. large. The more the addition of CMC water hyacinth mass, the value of the filtrate volume obtained from filtration loss will decrease because the mud is thicker and all the results meet API standards
Perbandingan Efisiensi Perlindungan Korosi Pada Baja Galvanis Dan Baja Karbon A-36 Dengan Penambahan Inhibitor
No full textGalvanized steel is zinc-coated steel (Zn) containing zinc with a high purity level (99.7%) plus a certain amount of black lead and aluminum processed under oxidation-free conditions to produce zinc-coated steel with reliable quality. There are various methods that have been done to reduce the rate of corrosion in metals, one of which is by adding corrosion inhibitors. Guava trees are one type of plant that can be used as a corrosion inhibitor because they contain tannins in their leaves. This study aims to obtain the effect of inhibitors on the rate of corrosion in peat water media. The method of measuring the corrosion rate used is the weight loss method. The materials used in this study were galvanized steel and A-36 carbon steel which were given varying inhibitors, namely 7%, 9%, 11% and were soaked for 25 days. The results of the study of galvanized steel and A-36 carbon steel in peat water media and the addition of guava leaf extract as an inhibitor showed that the inhibitor had a significant effect on the corrosion rate, as can be seen from the lowest corrosion rate value in galvanized steel of 0.045 mm/y with an inhibitor concentration of 9% and the lowest corrosion rate value in A-36 carbon steel of 0.076 mm/y with an inhibitor concentration of 11
Penegakan Hukum Terhadap Pelaku Tindak Pidana Pencurian Kelapa Sawit Di Perkebunan Warga Diwilayah Hukum Polres Kuantan Singingi
No full textTheft of palm oil plantation products as regulated in Article 107 of Law Number 39 of 2014 concerning Special Plantations, however in reality in the field law enforcers use Article 362 of the Criminal Code or Article 363 of the Criminal Code so that there is a wrong application of the law by Investigator. The main problem in this research is how to implement law enforcement against perpetrators of palm oil theft in the jurisdiction of the Kuantan Singingi Police and obstacles to law enforcement against perpetrators of palm oil theft in the jurisdiction of the Kuantan Singingi Police. The research method used is Observational Research by means of Survey, namely interviews as a data collection tool. The nature of the research, this research is descriptive analytical, namely providing a clear and detailed description of an incident that occurred regarding law enforcement against perpetrators of criminal acts of theft of palm oil plantation products in the Kuantan Singingi Police Legal Area. The results of this research indicate that law enforcement against perpetrators of criminal acts of theft of palm oil plantation products applies Article 362 or Article 363 of the Criminal Code. The reason investigators did not use Article 107 letter D of Law Number 39 of 2014 concerning Plantations was because if they used the plantation law, the plantation owner had to be able to show the formal requirements for legal entity, area certificate, plantation permit and other formal requirements. And the obstacles to law enforcement in the Kuantan Singingi Police jurisdiction are the large number of laws and regulations that regulate criminal acts in Indonesia in particular, the law enforcement apparatus factor because there are still many investigators who do not have a bachelor's degree in law, facilities and infrastructure factors and level limitations. The quality of public legal awareness is partly due to a lack of knowledge and understanding about the extent of influence and activities carried out on plantation crimes
Penyelesaian Sengketa Mengenai Kepemilikan Ganda (overlapping) Hak Milik Atas Tanah Berdasarkan Peraturan Pemerintah No. 24 Tahun 1997 Di Kecamatan Mandau
No full textOwnership of land is legally recognized only if it is first registered with the land office, in accordance with the provisions of Government Regulation No. 24 of 1997. One of the factors contributing to dual ownership is the negligence of landowners who fail to process the transfer of ownership after purchasing the land and do not maintain their land, causing it to be classified as abandoned land. Since the original seller has passed away and locating the heirs is difficult, the current landowner issues an SKGR (Certificate of Land Ownership) as proof of ownership to resell the land to a new buyer. As a result, two ownership records exist for the same piece of land. The research problem is: What are the factors that contribute to disputes over overlapping land ownership rights, and how is the resolution process conducted by the National Land Agency (BPN) in Mandau District? This study adopts a sociological/empirical legal research approach and is descriptive-analytical in nature. By integrating these two approaches, the research examines real conditions in the field while analyzing relevant legal provisions and linking them to actual circumstances.The data sources consist of primary and secondary data, while data collection methods include interviews, observations, and documentation. The conclusion of this study is that negligence in land sale and purchase transactions, which fails to transfer ownership and neglects to maintain the land, makes it easy for new land ownership certificates to be issued. To resolve overlapping land ownership disputes, a deliberation and family approach is taken. The agreed-upon solution is the issuance of a new land certificate by the National Land Agency (BPN) as proof of legitimate ownership, with the SKGR serving as the basis for its issuance. Since this dispute did not reach the court, the land office has the authority to issue a new certificat
Pengaruh Proses Pengelasan Terhadap Kekerasan Dan Laju Korosi Pada Material Baja A36
No full textASTM A36 type low carbon steel is a material that is widely used as a general construction material, this is because A36 steel has high ductility so that in its use A36 steel often undergoes a welding process. This study aims to find out how welding affects the hardness, corrosion rate and microstructure of A36. The hardness testing and corrosion rate measurement methods used are the B-type rockwell method and the weight loss method. The results of the study showed that welding increased the hardness of the material. The hardness of weld metal is higher than that of base metal for all current variations. On the contrary, welding increases the rate of corrosion. The lowest corrosion rate is shown by unwelded metal, which is 0.33 mm/y and the highest corrosion rate is shown by metal welded with a current of 90 A, which is 0.602 mm/y
