One of the reasons the Sugar Factory failed to meet its sugar production target was due to damage to the machine components, particularly at the milling station, where the milling rollers are located. The milling rollers play a crucial role in extracting juice from sugar cane, separating the juice from the bagasse, and measuring the raw juice before it enters the purification process. This unit is designed to maximize raw juice yield while minimizing the amount of bagasse. The milling rollers are arranged in a triangular configuration of three mills, with a milling path between the front and rear rollers that can move forward and backward. Several common issues affect the milling rollers, including surface wear, damage from excessive loads, and wear from repeated friction between the rollers and the sugar cane. Sugar cane itself contributes to roller wear due to its composition, which includes water, sucrose, cellulose, lignin, hemicellulose, ash, and silica. These substances are highly corrosive, even to stainless steel, and act like abrasives against the rollers. The usual remedy at the factory is to weld stainless steel onto cast iron rollers. However, this method has only been moderately effective, as the rollers continue to experience wear after a short period. Based on field observations and literature reviews, some suggested solutions include more frequent cleaning and applying a tungsten coating to the roller surfaces.

Vegetable crops need sufficient water to support growth. Lack or excess of water will cause stunted growth and even death of plants due to dryness or root rot. Appropriate irrigation technique is the key success in cultivating vegetable crops. Kelompok Kerja (Pokja) RT 01 RW 04, Karanglo Indah has a work program, namely women empowerment in supporting family food availability, by cultivating vegetables in the house yard. The problem is in watering. Technical guidance is provided through presentation, discussion and demonstration activities. Presentation and discussion aim to increase knowledge and comprehension of irrigation systems, equipment procurement, installation procedures, operating and maintenance procedures for drip irrigation. The demonstration aims to improve skills in carrying out procedures that have been presented in the presentation and discussion. The results obtained are increased knowledge, comprehension and skills for implementing drip irrigation so that better quality vegetables are produced.
