Abstract

Postharvest handling of candlenut in the traditional way is less effective and efficient. A worker is only able to break as much as 9–10 kg of candlenut/day and this also causes high work fatigue, besides thas many kernels are broken and destroyed (percentage og intact round kernels is only 40–60 %) so the price of candlenut becomes cheaper. Therefore, a candlenut crushing machine is needed with an optimum rorational speed that able to provide optimal and consistent energy to candlenuts crushing result. The candlenut material was dried at at 90 ˚C for 3 and 4 hours, then put it in ice water at 5 ˚C for 15 minutes. It was drained for 20 minutes and a drop test was carried out to find the optimum energy and rotational speed in cracking the candlenut. The result of rotaional speed are set up on the candlenut shell breking machine. Optimum solving result obtained of 490,5 Joules. Equivalent to candlenut dropped from a height of 5 meters with a rotating speed of 337,88 rpm. Keywords:  Candlenut, Post Harvest, Rotational Speed

Abstract

Indonesia has a lot of diversity, one of which is in food. Carbohydrates are basic food needs that must be met, in Indonesia there is the potential for various alternative foods. One of the alternative food ingredients producing carbohydrates is hotong. Hotong is a plant that is often found in Indonesia but has post-harvest constraints, namely in the sowing process. Therefore, research was conducted to determine the performance of an abrasive roll type grinding machine with the characteristics of hotong seeds. The research was conducted at PT. Daud Teknik Maju Pratama in November 2022. The treatment of hotong seeds that are sprayed as many as three passes with various levels of rpm speed, namely 806, 940, and 1128 rpm and carried out three repetitions at each rpm. The performance test results of the crushing machine showed the highest scattered capacity and shrinkage at a rotating speed of 1128 rpm, the highest yield and effectiveness of skin separation at a speed of 806 rpm, while at the highest polishing quality at a speed of 940 rpm. Rotating speed affects the sowing results, the faster the engine rotation speed, the quality and capacity of the sowing will increase. In addition, the tilt angle of the machine also affects the result of the sowing capacity. The terminal velocity value is influenced by the weight of the hotong seeds, the higher the weight on the sample, the higher the terminal velocity value obtained. Keywords:  Abrasive Roll, Hotong, Polisher.

Abstract

Bioethanol is a promising alternative biofuel for reducing gasoline consumption. Indonesia's bioethanol industry is expanding to achieve the energy mix target through Pertamax Green 95. The government also focuses on energy transition and environmental concerns, especially in the transportation sector. This research aims to inventory and assess the impacts of bioethanol production from cassava in Indonesia and analyze the feasibility of bioethanol consumption in vehicle exhaust emissions. The research method utilizes Life Cycle Assessment (LCA) and emission mass balance as the essential analytical tools. The LCA analysis refers to SNI ISO 14040:2016 and SNI ISO 14044:2017, with a cradle-to-gate scope using ReCiPe 2016 Midpoint (H) to assess the potential environmental impact of Global Warming Potential (GWP), Stratospheric Ozone Depletion (SOD) and Terrestrial Acidification (TAC). Whereas vehicle emission feasibility is analyzed using the emission mass balance method to calculate emission concentrations. The research result shows the environmental impacts per liter of bioethanol production from cassava were GWP 11.88 kg CO2 eq, SOD 5.9x10-6 kg CFC11 eq, and TAC 0.04 kg SO2 eq. Emission feasibility analysis signifies that bioethanol combustion vehicles are lower than conventional gasoline. Therefore, it indicates energy and environmental added value through its life cycle.

Abstract

Melons are become a popular fruit cultivating inside the greenhouse using the drip irrigations in Indonesia. The application of internet of things-based monitoring is beneficial to optimize cultivation management. Another issue on melon cultivation inside the greenhouse is automation of the water and nutrient delivery. However, currently monitoring and control is expensive and difficult to modify by farmers. The aim of this study was to develop a low-cost technology and easy to use by farmers using internet of technology. The method used in this study consisted of analysis, design and implementation. The result of this study was a system monitoring to monitor air temperature, air humidity, media humidity and solar radiation inside the greenhouse integrated with nutrient or water delivery using drip irrigation. A web-based dashboard was developed as a user interface for the farmers and users. The overall cost to develop a system monitoring and control was 358.24 USD not including the water thank and nutrient delivery system (pump and irrigations pipe). The system was deployed and tested at Agribusiness and technology park IPB University.

Abstract

Pulung Kencana Village is one of the villages in Tulang Bawang Tengah District, West Tulang Bawang Regency, Lampung Province, which is still facing challenges in managing organic waste and drought due to climate change. Community empowerment activities in Pulung Kencana Village were carried out to increase awareness regarding climate change mitigation through biopori technology. Biopori is a simple technology that is useful for increasing water infiltration, managing organic waste, and reducing greenhouse gas emissions. The program involved some of the people of Pulung Kencana Village and students of SMKN 1 Tulang Bawang Tengah. Participants were given socialization regarding the importance of biopores in mitigating climate change, followed by a demonstration of making biopore holes. The pre-test and post-test results show an increase in public knowledge regarding biopori. This activity succeeded in creating 6 pilot biopore holes and received a positive response from the community who were interested in increasing the application of biopore technology in their area. Continuous monitoring by the community and local government support is very necessary and is expected to increase the sustainability and benefits of this program in the long term.

Abstract

Recently, melon cultivation in controlled environments such as greenhouse are popular to improve productivity and quality. However, environmentally friendly productions are necessary for preserving ecosystems and reducing environmental impact. This research aimed to evaluate the environmental impact using a life cycle assessment approach. Research was conducted using a life cycle assessment with six categories evaluated such as Global Warming Potential (GWP), Stratospheric Ozone Depletion (SOD), Terrestrial Acidification (TAC), Freshwater Eutrophication (FEU), Terrestrial Ecotoxicity (TEC), and Human Carcinogenic Toxicity (HCT) for kilograms of fresh melon. The result of GWP was 2.137 kg CO2 eq; SOD at 0.39(10-5) kg CFC-11 eq; TAC at 3.93(10-3) kg SO2 eq; FEU at 0.44(10-3) kg P eq; TEC at 4.62 kg 1.4-DCB eq; and HCT at 0.13 kg 1.4-DCB eq. Furthermore, the main contribution of environmental impact was cultivating media such as cocopeat and rice husk charcoal. The result of this research is important to improve greenhouse-based melon production. Keywords: Greenhouse, GWP, Life cycle assessment, Melon.
