Abstract

In Karang Kelok hamlet, West Monjok, Mataram, there are currently 2 Home Industries (IRT) that make tofu and are known as Javanese tofu. Because the texture is different from the Lombok tofu in general, this tofu is in great demand by the wider community. So the demand in every day is very much. One of them belongs to Tin's mother. This IRT is able to absorb 3 workers. Every day able to spend 60 kg of soybeans. In producing the tofu, this IRT still uses the traditional method, especially when pressing the tofu is still done by overlapping 1-3 pieces of stone with different weights. Pressing in this way has weaknesses, including security and work safety issues. This condition is also one of the obstacles to be able to produce more tofu products. This pressing is done one by one and in a row, so it also takes up a wider area. Based on these problems, it is necessary to plan and manufacture hydraulic system tofu pressing tools so that the resulting product increases. The purpose of this service is to get a smaller time and area for pressing in the tofu-making process. The method used is to socialize the use of a hydraulic system tofu press. The results obtained are that this tofu press tool can shorten the average pressing time of 4 minutes and reduce the working area of pressing from 3 meters to 1 meter. And it can also reduce the risk of work accidents due to the fall of the crushing stone.

Abstract

Pohon enau (Arenga pinnata), dikenal juga sebagai pohon aren, merupakan salah satu dari banyak jenis flora yang ada di Indonesia. Tanaman ini memiliki fungsi produksi yang menghasilkan berbagai komoditi yang bernilai ekonomi tinggi dan berpotensi jika diusakan dengan secara baik. Seluruh bagian tanaman dapat diolah menjadi berbagai produk pangan dan non pangan. Wilayah NTB terdapat sentra produksi gula aren dan merupakan produk unggulan nasional dengan kualitas yang baik. Salah satu tempat produksi gula aren yaitu rumah produksi bapak Saiful Bahri di Desa Sesaot Lombok Barat. Gula aren yang diproduksi menggunakan cetakan tradisional berupa batok kelapa, hasil yang didapatkan berupa bentuk setengah bola dengan berat kurang lebih 1,5 kg. Harga yang ditawarkan dengan bentuk tersebut seharga Rp 20.000. Pada kegiatan pengabdian ini akan dilakukan inovasi terhadap pengolahan air nira menjadi gula aren briket.

Abstract

AbstrakKelompok tani sinar harapan memiliki permasalahan perawatan padi berupa biaya dan waktu semprot padi yang terus meningkat. Melalui program Pengabdian Kepada Masyarakat (PKM) ini dihasilkan dan diberikan alat semprot kepada kelompok tani sinar harapan di desa Setanggor sebagai upaya untuk meningkatkan dan mempermudah dalam penyemprotan padi oleh para petani. Oleh karena itu, hal ini menjadi isu yang perlu diselesaikan dalam peningkatan hasil pertanian. Mesin alat semprot ini didesain dan dibuat untuk mengatasi permasalahan seperti mempermudah dan mempercepat semprot padi. Selain pembuatan dan serah terima alat semprot, pelatihan pengoperasian, dan perawatan mesin dilakukan secara Bersama-sama dengn masyarakat dan tim pengabdian dalam program ini. Hasil pengabdian menunjukkan bahwa waktu semprot dan proses semprot pada padi lebih cepat, sehingga mengurangi biaya untuk upah yang dikeluarkan petani. Terlebih lagi, para petani di kelompok tani sinar harapan sudah melewati usaha produktif. Sehingga program ini sangat membantu para petani. Diharapkan program keberlanjutan pada alat yang berbeda lainnya untuk mendukung kemandirian para petani. Kata kunci: alat semprot; kelompok tani sinar harapan; pengabdian kepada masyarakat. Abstract The Sinar Harapan Farmers’ Group faces challenges in rice cultivation, specifically the rising costs and time required for rice spraying. Through this Community Service Program (PKM), a sprayer was developed and provided to the Sinar Harapan Farmers’ Group in Setanggor Village as an effort to improve and streamline rice spraying for farmers. Therefore, this issue must be addressed to increase agricultural yields. This sprayer was designed and built to address issues such as simplifying and speeding up rice spraying. In addition to the construction and handover of the sprayer, training on operation and machine maintenance was conducted jointly with the community and the service team as part of this program. The results of the community service initiative show that the spraying time and process for rice are faster, thereby reducing labor costs for farmers. Furthermore, farmers in the Sinar Harapan farming group have already achieved productive outcomes. Thus, this program is highly beneficial to farmers. It is hoped that sustainable programs involving other types of equipment will be implemented to support farmers’ self-reliance. Keywords: community service; sinar harapan farmers' group; sprayer.

Abstract

Desa Sesait memiliki potensi limbah biomassa yang melimpah, namun belum dimanfaatkan secara optimal sebagai sumber energi alternatif. Kegiatan pengabdian ini bertujuan meningkatkan kapasitas masyarakat dalam pengolahan limbah biomassa menjadi briket melalui penerapan mesin pencetak briket. Kebaruan kegiatan ini terletak pada integrasi teknologi mesin pencetak briket dengan pemberdayaan berbasis kelompok yang menghasilkan produk energi terukur serta meningkatkan kapasitas masyarakat. Program ini mendukung pengelolaan limbah biomassa berkelanjutan dan penguatan ekonomi desa. Metode pelaksanaan menggunakan pendekatan partisipatif yang meliputi identifikasi kebutuhan, pelatihan teknis, dan evaluasi. Pelatihan melibatkan 30 peserta dari kelompok tani dan pemuda desa dengan materi proses pirolisis, pengolahan arang, pencampuran, pencetakan, dan pengeringan briket. Evaluasi menggunakan pretest dan posttest dianalisis dengan paired sample t-test. Hasil menunjukkan peningkatan signifikan pengetahuan, dari rata-rata 45,00 menjadi 96,00 (p = 0,000 < 0,05). Uji kualitas briket menunjukkan nilai kalor 4780 cal/gram, kadar air 7,5%, kadar abu 7,6%, dan waktu pembakaran 64,1 menit.

Abstract

Aluminum 6061 is one of the most widely used materials across various industrial sectors due to its good mechanical properties, lightweight nature, and corrosion resistance. However, in acidic environments, aluminum remains susceptible to corrosion, which can reduce its performance and service life. This study utilizes agricultural waste from kapok seeds (Ceiba pentandra) as an environmentally friendly corrosion inhibitor for Aluminum 6061. The extract was obtained through maceration using ethanol as the solvent and was applied in corrosion tests of Aluminum 6061 in 1 M HCl solution. The evaluation was conducted using potentiodynamic polarization (PDP) and electrochemical impedance spectroscopy (EIS) techniques, along with isothermal adsorption analysis to understand the adsorption mechanism of the inhibitor on the metal surface. The results showed that the kapok seed extract significantly increased polarization resistance and reduced the corrosion rate, achieving a maximum inhibition efficiency of 78.77% at an optimal concentration of 3000 ppm. The inhibitor adsorption followed the Freundlich isotherm model, indicating strong binding interactions between the inhibitor molecules and the aluminum surface. Therefore, kapok seed extract has great potential as an environmentally friendly and cost-effective corrosion inhibitor for aluminum-based industries.

Abstract

Polyvinyl alcohol (PVA) has promising potential as gas purification membrane and bioplastic substitute for conventional materials. PVA material was reinforced with nanocellulose timoho fibers (NCT). Ten grams of NCT, 30 mL of distilled water, and 10 grams of PVA were stirred (500 rpm) at <80 oC on a magnetic stirrer until gel formed, then spread on a Petri dish and dried in an oven at 50 °C for 21 hours. The elongation, tensile strength, and elastic modulus test results of PVA-NCT biocomposites showed increases of 21%, 29.97%, and 31.57%, respectively, compared to PVA biocomposites. This was due to the role of NCT as reinforcing agent and the mobility of PVA when tensile test. SEM morphology showed a fine speckled surface due to clumping. The thermal resistance of biocomposite increased due to the good interfacial bonding between NCT and the PVA matrix, thereby reducing the rate of weight loss. Exothermic reactions occurred in both biocomposites. The PVA biocomposite had a melting temperature of 110.34 °C, and PVA-NCT biocomposite 119.83 °C. The antibacterial activity of the PVA biocomposite has a lower inhibitory power compared to the PVA-NCT biocomposite. These biocomposites can be used for membrane materials and environmentally friendly bioplastics.
