Abstract

One of the consequences of excessive palm oil use is the production of waste palm oil (used cooking oil). To overcome this problem, efforts are needed to convert used cooking oil into more valuable products, such as biodiesel; because of its high fatty acid content, the used cooking oil has considerable potential in developing biodiesel fuel. This research aims to utilize used cooking oil in making biodiesel using heterogeneous catalyst ash derived from Nipah fruit skin calcined at 500 °C for ± 4 hours. Nipah is a type of palm (monocotyledon) that grows in mangrove forest ecosystems, in tidal areas near the seaside, or offshore. The characteristics of parts of Nipah, such as leaves, and skin, chemically contain a lot of cellulose, hemicellulose, and lignin and contain inorganic elements such as Na, K, Cl, Mg, Ca, Si, P, S, and Al. The transesterification process reacts oil with methanol to produce methyl esters and glycerol.  Process variables, namely transesterification reaction time of 60, 90, 120, and 150 minutes, and the mole ratio of methanol to oil of 1:19, 1:21, and 1:23, were observed in this experiment. Biodiesel characteristics were obtained with a density of 860.2 g/mL and a viscosity of 2.37 mm2/s. They contained 44.14% Palmitic acid and 43.04% Octadecenoic acid (oleic), which is to the Indonesian National Standard (SNI). The maximum yield obtained was 93.3598% using a mole ratio of oil: methanol 1:23 at 60°C for 120 minutes, TFT 1:1, and 3% catalyst mass. The results obtained in this study indicate that Nipah fruit skin-based catalysts can be used to produce biodiesel.

Abstract

This beach, which is located in Aceh Province, especially Bireuen Regency, Jangka District, Kuala Ceurape, is an tourist beach area, aquaculture,e and also a settlement. Several efforts to control sedimentation and erosion have been carried out by constructing coastal protection buildings on the coast. However, in the estuary, there are no coastal protection structures such as jetties. Estuaries have quite high economic value because they function as connecting channels between sea and land. The height of the wave currents around the estuary can cause the accumulation of sediment or silt of the beach by erosion which can result in decreased utilization of the coast around the estuary. Therefore, it is necessary to analyze the impact of coastal protection construction planning to determine the formation of sedimentation and erosion that occurs around the coast. This study used the Delft3D application to simulate changes in coastlines and estuaries over a period of 5 years. The data used in this study are wind data for 10 years from 2012 to 2021, depth data, tidal component data, factor morphology calculations, significant wave height calculations (Hs,), and significant wave periods (Ts). This simulation uses 4 (four) wind directions, namely North, Northeast, East, and Northwest directions. The results of modeling simulations over a period of 5 years show that the beach condition with the planned construction of the coastal protection has progressed along the coastline by ± 77,053 meters and progress of around ± 77.421 meters on the coast. On the contrary, it experienced a coastline retreat of ± 143.076 meters and experienced a shoreline advance of around ± 84.647 meters in the estuary. So it can be concluded that the construction of the Jetty building alone is not enough to reduce the occurrence of erosion and sedimentation problems around the coast, especially in the estuary. There is a need for the construction of other coastal protection structures.

Abstract

The availability of petroleum fuels derived from fossils is decreasing along with the increase in the human population. This study aims to create bio-charcoal briquettes derived from solid waste of patchouli oil refining. Research on the use of the by-products of the pyrolysis process on solid waste from patchouli oil refining for making bio charcoal briquettes was carried out using temperature variables of 300, 350 and 400 °C, raw material weights of 600, 1200, and 1800 grams and pyrolysis time variables of 60, 90, 120 and 150 minutes. Solid waste has first been cut into small sizes, dried in the sun first, and then put into a pyrolysis device to be carbonized according to predetermined variables. The results of pyrolysis were then put into a desiccator to cool for 30 minutes and then tested for moisture content, ash content, fly content, bound carbon content, calorific value, SEM test, and combustion rate. The best research results obtained were at a temperature of 400 °C, a raw material weight of 600, and a time of 150 minutes with a thermal value of 5,291 cal/g, a moisture content of 5.77%, an ash content of 4.28%, a volatile matter content of 9.11% and a bound carbon content of 77.42% and a combustion rate of 0.1841 grams/minute. The obtained calorific value shows that patchouli solid waste bio charcoal can be used as an alternative fuel that can be renewed and fulfills SNI 01-6235-2000.

Abstract

The variety and production continue of plastic has increased and it has brought difficulties in dealing with plastic waste disposed to nature and cannot be decomposed in a long time. Modified thermoplastic starch derived from sago palm crosslinked with polyurethane prepolymer obtained from diphenyl methane diisocyanate and castor oil polyol had better mechanical, thermal and chemical characteristics than bioplastics. In this study, eco-friendly plastics from sago starch modified with prepolymer polyurethane with the addition of chitosan as additive and polypropylene or polyethylene as matrix was produced. The research method conducted were consisting of several stages, preparation of thermoplastic starch, blending thermoplastic starch with polypropylene or polyethylene and plastic irradiation technology using gamma rays with dosage of 5, 10 and 20 kilogray (kGy). The effect of radiation technology on surface morphology of sago based eco-friendly plastic was analysed through Scanning Electron Microscopy (SEM) analysis to observe the effect of gamma rays exposure to the plastic surface. The result showed that the dots appearance on the surface and possibly shown non-uniformity of plastic surface due to less homogeneity of mixture when stirred. Thermoplastic starch was not blended perfectly into PP and this could be due to high temperature different required to melt PP while thermoplastic starch as an organic material cannot stand high temperature and become scorched at high temperature. To overcome this problem, mixing time should be increased to ensure high homogeneity. Overall, SEM analysis showed radiation does not provide effect to plastic surface morphology, which means it did not ruin the polymer structure as well as its binding. Similar appearance observed on the plastic surface morphology before and after radiation, even with highest radiation dose. From the analysis, it can be stated that radiation technology does not influence plastic surface structure, hence plastic binding was remain the same

Abstract

In this research, we propose time optimization for notifications to assist users in remembering their actions by taking into consideration the amount of time it takes for them to respond and react. Using the Q-Learning algorithm, this proposal calculates when the best time to send notifications to users' smartphones in order to remind them of something important. The time at which the message is sent will be adjusted depending on the replies of prior users, which may be transformed into feedback at any time that is convenient. Notifications will be sent out, either repetitively or not, depending on the appropriate time for each individual, with the goal of ensuring that users do not forget about activities that they have planned. The results of testing our technique using the dataset show that it may be used to improve the time at which notifications are issued to recipients. It is possible to experiment with a variety of different times for the delivery of alerts in order to determine which of these periods is most successful for prompting users to take action. As a consequence of this, the algorithm is able to accommodate specific characteristics of individuals and find solutions to problems using a variety of standard operating procedures. Our proposal has the potential to successfully maintain the notification execution time at the intended level, which will prevent users from becoming concerned about the volume of notifications. Users who do not see the notification initially have the opportunity to do so at a later time step, which guarantees that activity data will still be collected.

Abstract

Regional development is largely determined by the potential possessed by a region, the wisdom made by the local government must refer to the potential of areas that have the opportunity to be developed, especially the plantation subsector. The high demand for exports of plantation products has encouraged the development of a number of plantation commodities in various regions. Palm oil is one of the leading commodities in the plantation subsector in Aceh Province. Until now, oil palm is a prima donna crop of the people in the Aceh region and in several other regions. Palm oil is the development of an agribusiness-based plantation subsector. The activities of oil palm plantations and their derivative products provide high added value in the economic sector. The importance of developing oil palm plantations is increasingly felt in the impact on the workforce of both men and women who work in the oil palm plantation sector and its derivative sectors. Women are an important part of the palm oil industry that is always present in every chain of the palm oil production process. This impact can be seen from the increase in income of the farming community, resulting in an increase in the purchasing power of rural people, both for primary and secondary needs. Based on the role of oil palm in the rural economy and the development of oil palm plantation areas in the Aceh area. The selection of research sites is in the Western region of Aceh which includes: Aceh Singkil and Meulaboh Regencies and the Eastern region of Aceh includes: North Aceh Regency, East Aceh, Kuala Simpang. It is known that the region has many characteristics of the oil palm plantation industry in Aceh province.

Abstract

Agricultural development that is generally carried out in rural areas is very important for a country because it has a very broad role such as producing food for the people, providing a source of income and employment for rural residents, providing a source of raw materials for the industrial sector, encouraging national and regional economic growth and preserving the environment technological developments allow agriculture to have a new role as a source of energy for life in the form of biofuels. Dependence on energy sourced from fossil fuels, especially petroleum, is getting higher and has encouraged Indonesia to develop biofuels such as biodiesel given the availability of abundant raw materials in the form of palm oil. Currently, Indonesia is the largest producer of palm oil in the world. so that the community has an alternative choice of fuel to be used and dependence on fossil fuels can be reduced and improve the economic welfare of the community, especially oil palm farmers. The study covers the aggregate area of Aceh province and commodities restricted to biodiesel derived from palm oil as the leading raw material for biodiesel in Indonesia. The feasibility level of the region (west or east) of Aceh province that has the potential for biodiesel plant development is projected through a model and economic analysis. PT Perkebunan Lembah Bhakti (Astra Agro Lestari Tbk) in Aceh Singkil regency, Aceh province built 1,000 hectares of plasma oil palm plantations in an effort to increase the productivity of the company's management and improve the economy of the local community. PT Ika Bina Agro Wisesa in the Guha Uleu area, Kuta Makmur District, North Aceh Regencyaccommodates around 700 tons of palm oil bunch owned by local farmers.

Abstract

Two types of houses in North Aceh, Indonesia, are investigated in this study. Even though the hot and humid conditions throughout the year, most Indonesian stay in a house that uses natural ventilation due to energy poverty and economic conditions. Commonly, they rely on natural ventilation by opening windows to achieve thermal comfort in the indoor environment. Therefore, an on-site survey and questionnaire were performed on more than 240 occupants and 115 naturally ventilated houses to investigate thermal comfort performance between two houses based on thermal sensation vote (TSV) and thermal comfort vote (TCV). In addition, some questions related to thermal preference and body response are employed. This study also examines thermal comfort with a numerical simulations program called THERB for HAM, a coupled analysis software for heat, moisture, and air. The results show that the room comfort level was not optimal, where most occupants' feelings were warm and hot. However, type 1 is more comfortable than type 2, and simulation results confirm indoor environmental conditions. Furthermore, this study presents the adaptive behavior, where most occupants utilize the windows openings in the morning until noon and operate the fans during the night to modify indoor environment conditions to be more comfortable.

Abstract

Finding suitable water sources for fish and plant cultivation appears to be difficult. In addition, land scarcity is decreasing agricultural productivity, so it is crucial to combine land and water conservation technology with various vegetable varieties for optimal yields. Aquaponics is a sustainable farming method that combines aquaculture and hydroponics. This water system must regularly circulate through the growing medium to provide the plants with nutrient-rich, filtered water. This research develops a smart aquaponics system that uses a mobile application accessible via the internet to control and monitor acidity, water level, water temperature, and fish nutrition. In this system, sensors are installed to collect data, which is then sent to the Ubuntu IoT Cloud server, which can be accessed in real time over the internet. So as to preserve the purity and circulation of water. In this study, the waterlevel sensor has a 100% measurement success rate, the pH sensor has a 93 % measurement success rate, and the temperature sensor has a 96% measurement success rate. The temperature and pH range of the pond water are optimal for aquaponics at 25 to 35 degrees Celsius and 6,5 to 7,5, respectively, and the aquaponics monitoring system is functioning properly. A suggestion for future research is the development of an aquaponic system that can be modified based on the type of plant and its nutritional requirements.
