Abstract

Pupuk merupakan salah satu kebutuhan utama dalam melaksanakan kegiatan pertanian, namun saat ini pupuk subsidi yang didapatkan dari pemerintah kian dikurangi sehingga petani tidak bisa mencukupi kebutuhan pupuk untuk lahannya. Sedangkan pupuk non-subsidi harganya mahal sehingga membuat petani beresiko merugi. Dari kondisi tersebut kemudian terdapat gerakan kelompok tani yang berinisiatif untuk membuat pupuk/nutrisi sendiri yang terbuat dari bahan-bahan organik yang mudah diperoleh dan tidak memerlukan biaya yang besar. Kolaborasi antara warga Desa Papungan dan Pusat Pelatihan Pertanian dan Pedesaan Swadaya Alam Lestari Tanjungsari telah menghasilkan sebuah penemuan berupa nutrisi organik. Nutrisi ini mampu menggantikan penggunaan pupuk kimia dalam pertanian dan memiliki manfaat tambahan yaitu dapat digunakan sebagai pakan tambahan dalam budidaya ikan yang dapat meningkatkan pertumbuhan ikan. Berdasarkan hal tersebut dilakukan pemodelan matematika untuk menghitung berapa potensi hasil yang bisa diperoleh apabila petani beralih ke penggunaan nutrisi organik. Dengan menerapkan pemodelan matematika, potensi penghasilan yang dapat diperoleh adalah sebesar Rp. 3.519.300.000 dari potensi hasil panen sebesar 586,06 ton padi, 17 ton cabai, dan 40,926 ton ikan nila dari pemanfaatan lahan sebesar 140 hektar.

Abstract

The "Raja Gresik" meatball factory was established in 2008 and was established in 2018. One of the problems at this factory was that when carrying out the process of packaging meatball in plastic packs, there were packs whose quantity did not match the specifications for the number of meatball of that type. With the existing problems, it is hoped that this research can help the "Raja Gresik" meatball factory to reduce defects in calculating meatball in packs and make workers less tired because the design of the meatball counting tool is in accordance with the anthropomometry of workers. The existence of this tool can reduce losses from an inappropriate number of meatballs in the pack, which will effectively prevent product defects from excess or shortage of meatball. Also, the presence of this tool makes the packaging process time faster from 30 seconds to 23.43 seconds after using this tool. And it can be used for worker anthropometry, namely hand reach length, knee height and standing elbow height.

Abstract

UD. Hadhita Jaya Makmur was established in 1993 and located on Jalan S. Parman, Modopuro Village Rt.03, Rw.07, Mojosari District, Mojokerto Regency. The founder of this company is Mr. Drs.Munasrib, who is known in poultry farming activists, especially ducks. UD. Hadhita Jaya Makmur has ducks with a population of 3000 laying ducks, ducks at UD Hadhita Jaya Makmur produce about 2100 eggs every 2 days in December. UD. Hadhita Jaya Makmur strives to improve the quality of duck eggs by setting a target of feeding ducks as much as 500 kg every day for a population of 3000 ducks that are ready to lay eggs. Nevertheless, the use of manual methods in mixing duck animal feed ingredients has some negative impacts. The process of stirring duck animal feed takes quite a long time, which can reach 40 minute so that workers at UD. Hadhita Jaya Makmur experienced fatigue. One idea to be able to solve the problem is to design an animal feed mixer machine to provide significant results, providing results in accelerating the time of the 500kg per day animal feed stirring process which was originally at UD. Hadhita Jaya Makmur stirred animal feed ingredients in the process still using manual methods with a processing time duration of 43 minutes. After the design of the animal feed mixer machine, the process time of stirring animal feed ingredients to 15 minutes, the magnitude of the reduction in process time also affected the worker productivity index which was originally 19,3% to 55.5%.

Abstract

PT Benteng Api Technic was founded in 1997 and produces refractory bricks, refractory cement and various refractory materials. Refractory cement or castable currently still uses a pre-order system before the production process is carried out. During observations for seven days with 38 observations, there were activities that were felt to be less efficient, then the value stream mapping method was carried out to streamline waste. The result is a defect when the production process is finished, there is a repetition of the production process because it does not pass the feasibility test, processing because a lot of leftover material falls in the bagging section and the material is no longer used. Waiting is the average part of weighing materials/products of 1.54 seconds (waiting for the material composition recipe and weighing platform trouble/error). Material mixing section with an average/product of 1.82 seconds (waiting for machine repairs due to leaking air duct). Total production lead time is 3396 seconds. Once the waste is identified, the next step is to eliminate the activity by testing data adequacy and testing data uniformity. The results of the analysis of the castable production process contained 2 analyses, the first analysis by reducing activity time with an average total time of 3285 seconds/44 cement and the second analysis by reducing and eliminating the cement weighing activity in the bagging section with a total time of 2873 seconds/44 cement

Abstract

Alongside the increasing potential of the agriculture and plantation sectors in Minggirsari Village, Blitar Regency, there have been concerns among farmers regarding the decreasing supply of both subsidized and non-subsidized chemical fertilizers. However, these concerns were validated with the invention of an automatic anaerobic bioreactor by Nawang Sonia in 2023. The device is capable of reducing the fermentation process time from the initial 14-21 days to just 3-5 days. Although the designed device still had some functional limitations hindering its performance, a redesign was deemed necessary. The redesign was conducted using the Quality Function Deployment method through the distribution of questionnaires or Voice of Customer. Subsequently, a House of Quality was obtained, which served as the basic concept for the device's redesign. From this research, eight features were added to the device. The results showed that the device was more optimal, flexible, and effective than the previous anaerobic bioreactor design.
