Abstract

Acetone-butanol-ethanol (ABE) is a preferred alternative energy for SI engines. This research uses an experimental method with an automatic SI engine, RON-90 fuel mixed with ABE1 (12:8:1)v/v, ABE2 (15:10:1)v/v and ABE3 (1i8:12:1) v/v. Engine speed is 4000-10000rpm, and compression ratio is 11.6:1. Emission and engine performance testing used EPSG4-Gas analyzer and Dynotest-chassis type 50L-BRT. This research aims to explore the mixture of RON-90 and ABE to optimize performance and exhaust emissions. This research shows that torque increases by an average of 14.7% at an engine speed of 6000rpm. Power increased significantly with an average value of 9.5% at an engine speed of 8000rpm, MEP increased by 0.5%, and thermal efficiency increased by 7%. SFC experienced a fairly optimal decrease of 15.6% on average. The exhaust gas emissions produced are CO and HC. The reduction in CO and HC occurred in the ABE3 variant with values of 8.2% and 1.6%, respectively.

Abstract

The Garbage is residual material that has been disposed of and is no longer used, so that waste is considered something disgusting by some people. Garbage has two types, namely organic waste and inorganic waste. Therefore, good waste management is needed so that every day waste does not accumulate and does not disturb the surrounding environment. The purpose of this research is to design a garbage chopper that is useful for chopping organic and inorganic waste to help the waste processing process so that there is no buildup every day. The design of this chopping machine is made multi-functional that can chop organic or inorganic types of waste, designed according to the wishes of consumers or users and made ergonomically. The method used in this research is the Quality Function Deployment (QFD) method and the user's body Anthropometry so that the dimensions of the machine are in accordance with the user which causes the design to be ergonomic. The results of the research are to produce a design of organic and inorganic waste chopping machines that have specifications such as machines using mild steel so that they are easy to move, durable, speed up the chopping process because there is a speed setting, automatic. In addition, the machine has ergonomic dimensions from the results of the machine user's body measurements using the anthropometric method.

Abstract

Kunjang Village Market is located on Jl. Soekarno-Hatta, Kunjang Kidul Hamlet RT.02 RW.02 Kunjang Village, Kunjang District, Kediri Regency. The location of the Kunjang Village Market is about 30 km from the city center. There are 338 traders in Kunjang market tradisional  in total. However, with the large number of traders, it raises several problems, namely the amount of garbage that accumulates causing unpleasant odors and the handling of waste is carried out by burning so that the smoke spreads everywhere which disturbs the surrounding environment, especially residential areas. In addition, there is no garbage truck that transports it to the central waste collection center of Kediri Regency so that the waste is burned in an open place located behind the market. The purpose of this service is to improve waste management that is more environmentally friendly, as well as obtain by-products from waste processing to increase market income. The methods used in this service are training and assistance in processing waste into solid and liquid organic fertilizers, as well as processing inorganic waste (plastic waste) into shredded plastic and liquid fuel or oil processed by means of pyrolysis. The results of this service produce by-products in the form of solid and liquid organic fertilizers, marketable shredded sticks and liquid fuel (oil), as well as reducing environmental impacts due to the smoke from burning waste.BAHASA INDONESIA ABSTRACT: Pasar Desa Kunjang terletak di Jl. Soekarno-Hatta, Dusun Kunjang Kidul RT.02 RW.02 Desa Kunjang, Kecamatan Kunjang, Kabupaten Kediri. Lokasi Pasar Desa Kunjang terletak sekitar 30 km dari pusat kota. Total pedagang di pasar tradisional Kunjang sebanyak 338 pedagang. Namun dengan banyaknya jumlah pedagang, maka menimbulkan beberapa permasalahan yaitu jumlah sampah yang menumpuk sehingga menimbulkan bau tak sedap dan penanganan sampah dilakukan dengan dibakar sehingga asap menyebar ke mana-mana yang mengganggu lingkungan sekitar terutama pemukiman penduduk. Selain itu tidak adanya truk sampah yang mengangkut ke penampungan sampah pusat kabupaten Kediri sehingga sampah di bakar pada tempat terbuka yang terletak belakang pasar. Tujuan dari pengabdian ini yaitu untuk memperbaiki pengelolaan sampah yang lebih ramah lingkungan, serta mendapatkan produk sampingan hasil pengolahan sampah untuk menambah pendapatan pasar. Metode yang digunakan dalam pengabdian ini yaitu pelatihan dan pendampingan pengolahan sampah menjadi pupuk organik padat dan cair, serta pengolahan sampah anorganik (sampah plastik) menjadi plastik cacah dan bahan bakar cair atau minyak hasil proses dengan alat pirolisis. Hasil pengabdian ini menghasilkan produk sampingan berupa pupuk organik padat dan cair, pastik cacah yang layak jual dan bahan bakar cair (minyak), serta mengurangi dampak lingkungan akibat asap pembakaran sampah.

Abstract

Improving combustion efficiency while reducing fuel consumption remains a major challenge in the development of spark-ignition (SI) engines. Oxygenated alcohol fuels have attracted considerable attention because of their potential to improve combustion quality and energy conversion efficiency. However, previous studies have mainly focused on single or binary alcohol blends, whereas comprehensive optimization of ternary methanol–butanol–ethanol (MBE) blends under different engine operating conditions remains limited. This study investigated the combined effects of MBE blend ratio (9–17 vol.%), engine speed (4000–9000 rpm), and ignition timing (15–25°CA) on SI engine performance using Response Surface Methodology based on a Face-Centered Central Composite Design (FCCD). Power, specific fuel consumption (SFC), and thermal efficiency (TE) were selected as response variables, and twenty experimental runs were conducted to develop quadratic prediction models and determine the optimum operating condition through desirability-based multi-response optimization. The developed models exhibited excellent predictive capability, with coefficients of determination (R²) exceeding 0.99 and statistically insignificant lack-of-fit values. Engine speed was identified as the most influential factor affecting all responses. The optimum operating condition was obtained at 16.21 vol.% MBE, 7015.42 rpm, and 24.31°CA, producing 6.32 kW power, 0.499 kg/kW·h SFC, 22.44% thermal efficiency, and an overall desirability of 0.973. These findings suggest that FCCD-based multi-response optimization is an effective approach for improving SI engine performance using ternary MBE fuel blends.
