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.

The primary function of mobile robots is to transport various loads, including their own weight and additional cargo. Ensuring adequate torque in the wheel motors is crucial for effective load-bearing and movement. This study investigates the load-carrying capabilities of the TT DC gearbox motor, a popular and cost-effective choice for small robots. A mobile robot equipped with four TT DC gearbox motors and employing skid steering locomotion was constructed for this purpose. The robot featured a container designed to carry sand, and its load capacity was tested by gradually increasing the weight until the robot could no longer move. Experimental results showed that the maximum load the robot could carry on a flat surface was 4000 grams, which corresponds to 1000 grams per 5 cm diameter wheel, driven by a stall torque of 0.08336 Nm (0.85 kg.cm). This finding is consistent with the motor's specified stall torque of 0.8 kg.cm at 6V. These results suggest that the maximum load of a mobile robot can be predicted using the motor's stall torque specification and the wheel radius through the total tractive effort (TTE) formula. This study offers valuable insights into estimating the performance limits of DC gearbox motors used in driving mobile robots.

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.

Desa Niwak bertempat di pegunungan Meratus yang belum tersentuh oleh pembangunan pemerintah karena letaknya yang terpencil. Jalan, listrik dan signal handphone belum dapat ditemui. Namun, oleh karena letaknya di pegunungan, desa ini mempunyai potensi air yang dapat dikembangkan menjadi pembangkit listrik tenaga mikro hidro. Dari survey yang telah dilakukan pada sungai yang letaknya 1200 meter dari desa, didapatkan debit aliran potensial sebesar 41 liter per detik dan ketinggian head 12 meter. Energi air ini dapat dikonversikan menjadi energi listrik setara 3 kW atau 3000 watt setelah dikurangi kerugian-kerugian. Untuk mendapatkan kestabilan suplai air, dirancang sebuah dam dengan sebuah penstock yang dihubungkan dengan turbin air. Proyek ini merupakan bagian dari Program Pengembangan Dayak Meratus di Kalimantan Selatan oleh Komunitas Tritunggal Mahakudus di bawah koordinasi Keuskupan Banjarmasin.
