Abstract

The energy crisis is approaching, not only Indonesia but also all around the world. This requires technological innovation to overcome it, such as; making alternative fuels that are cheap and easy to produce. One alternative way to overcome this problem is to make alternative fuels in the form of bio briquettes by utilizing organic waste (sugarcane bagasse and sugarcane leaves). This study aims to study the effect of the ratio of leaves and bagasse as main sources and using lignin as the adhesive, to produce bio briquettes. The ratio of leaves and bagasse used in this research were (30: 70). The pyrolysis process is carried out to obtain charcoal and sieved at 30 mesh. The charcoal is then mixed with the adhesive. The ratio of the amount of lignin with a mixture of sugarcane bagasse and leaves were (10: 90); (15: 85); (20: 80); (25: 75); (30: 70), and mold. The briquettes formed dried in an oven at 105 oC for 1 hour. The results of this study showed that the lowest calorific value was 4860 cal/kg at 10% lignin content and the highest calorific value at 25% was 5876 cal/kg. The results of the analysis of the lowest moisture content (%) were at 10% lignin content of 0.0781% and the highest moisture content was 0.1387% at 25% lignin content.

Abstract

The aims of this brief overview are providing the knowledge about the physical and chemical properties of perovskite oxides in various synthesis method and the correlation of its performance for separating oxygen from air. Perovskite oxide showed excellent conductor of ion and electron, simultaneously through oxygen lattice in the crystal structure. In the present review, we have presented the detail on the crystal structure and the factor that affect the pseudo-crystal, various synthesis method i.e., solid-state, sol-gel, combustion, and co-precipitation. It has been completed with the discussion of the characteristic and the mechanism of the perovskite to separate oxygen from air

Abstract

Darurejo Village, Plandaan District, Jombang is an onion horticulture area where the highest productivity level is in the Jombang Regency of 3990 kw and 38 kw/ha. However, the onion sales are not optimal so farmers often experience losses. Therefore, we service activities regarding the processing and management to enhance the effectiveness. Coinciding with the COVID-19 pandemic and the enactment of the government's decision to Implement Emergency Community Activity Restrictions (ECAR) the implementation of counseling is carried out online. The online activity was carried out through the WhatsApp Group, on Saturday, July 31, 2021, from 11.00-14.00 WIB, which was attended by 25 village cadres. This outreach activity was carried out by providing 2 materials, including basic knowledge of onion and the resulting products such as fried onion, onion baceman, and onion powder which have great potential to be widely sold, and the introduction of automatic peeling machines to increase the quantity and quality of productions through online and offline meeting on August 28, 2021. It is hoped that the community will be able to process and manage the onion shallot potential products.

Abstract

UD. Rahayu Food was one of pioneer on the special tofu production with soft texture called “tahu susu”. During pandemic of Covid-19, the productivity of UD. Rahayu Food was decreased and it had an impact on their sales. Optimalization of its production process by technology application would be one of the solutions for UD. Rahayu Food. The aims of this community service at UD. Rahayu Food is upgrading their productivity rate by production tools improvement. The production tool that was developed on this activity is symmetrical tofu cutter. This equipment was utilized for cutting of tofu symmetrically before being processed into “tahu susu”. Moreover, this cutter could speed up the slicing step process and their product quantity would be raised. Hopefully, provision of this symmetrical cutting tool could increase the income of UD. Rahayu Food during Pandemic Covid-19
