Abstract

Sinogo farmers, starting in November 2022 have cultivated Vanilla plants (Vanilla planifolia Andrews) in a greenhouse using planting medium in the form of mixture of soil, manure and cocofiber in a ratio of 1 : 1 : 1. The use of cocofiber causes the planting medium to dry out quickly. In 2023, Sinogo farmers had problem of limited water for watering because the water used comes from springs, which are very small during the dry season. The aim of the community service activity was to provide information about water-saving drip irrigation technology and to apply drip irrigation techniques to vanilla cultivation in greenhouses. Community service begins with survey activities to determine regional conditions and the level of farmers' understanding of drip irrigation technology. The next stage was education and practice of drip irrigation technology. Evaluation monitoring was carried out to determine the results of drip irrigation practices. The survey results showed that 87% of farmer group members did not know about drip irrigation techniques and they were very interested in implementing this technology. As many as 100% of respondents expressed interest in implementing drip irrigation technology on vanilla plants. After providing service to the Sinogo farmer community, they understood the drip irrigation technique, which was a water-saving irrigation technique. The results of the community service implementation showed that drip irrigation was running but was still limited because little water was stored due to low rainfall until December 2023. The conclusion was that most members of farmer community did not understand drip irrigation techniques. The success of drip irrigation techniques was influenced by the availability of water sources.

Abstract

Desa Kalak di Kec Donorojo, Kab Pacitan merupakan salah satu sentra pembudidaya kelapa sekaligus pengrajin gula kelapa. Kelapa dan produk turunannya menjadi salah satu prioritas komoditas yang ditumbuhkembangkan oleh pemerintah kabupaten Pacitan. Namun demikian sampai dengan saat ini belum tersedia peta tematik mengenai kelapa dan pengrajin gula kelapa, sehingga para pemangku kepentingan tidak dapat mempelajari kondisi populasi pohon kelapa dan pengrajin gula kelapa secara tepat dan kekinian. Karena itu program ini bertujuan membantu menyediakan peta tematik kelapa dan pengrajin gula kelapa desa Kalak agar dapat membantu pengembangan kawasan dengan baik. Program dilaksanakan dengan metode kolaborasi dan partisipatif antara perguruan tinggi, pemerintah desa, dan masyarakat. Program penyusunan terdiri atas kegiatan: kajian kondisi eksisting, wawancara dengan perangkat desa dan dusun, pembuatan peta digital dari peta analog, pengambilan data lapangan, dan penyajian peta. Sasaran penerima manfaat adalah pemerintah desa, kecamatan, hingga pemerintah kabupaten. Peta digital kemudian dapat dikembangkan menjadi sistem informasi geografis (SIG) yang dapat digunakan sebagai acuan pengembangan kawasan oleh pemerintah daerah. Peta digital juga dapat digunakan sebagai media promosi daerah kepada investor, lembaga donor, maupun perguruan tinggi. Peta digital yang dihasilkan dapat menyajikan area persil kepemilikan lahan, pemanfaatan lahan baik untuk kelapa maupun campuran, dan po.pulasi pohon kelapa di blok-blok lahan yang datanya telah dilengkapi. Peta digital juga dimungkinkan diberi tambahan informasi lain seperti pembayaran PBB, status kesehatan warga, dan sebagainya.

Abstract

As perishable food, the sterilization process in milk was essential to obtain long shelf life. In industry, sterilization process was performed using high temperature in very short time. This process was known as Ultra High Temperature (UHT). UHT sterilization process could be done with Tubular Heat Exchanger (THE) or Plate Heat Exchanger (PHE). This research was aimed to compare the heat transfer rate from THE and PHE in PT.ZYX milk sterilization plant. Based on analysis, heat transfer rate of PHE was higher than THE. Both of them were using hot water as medium. The simulation with steam as heat transfer medium showed that the heat transfer rate was not much different with hot water in THE.

Abstract

Fruit-infused tea become one of the exciting innovations in recent years. Fruit addition could improve the freshness and richness of tea drinks. Pineapple has good potency when used in the making of fruit-infused tea. The soaking time and size of fruit pieces were essential to determine because there is a solid-liquid extraction process in making pineapple-infused tea. This research aimed to assess the effect of soaking time and the size of fruit pieces on the characteristics of pineapple-infused tea. This research used Complete Block Design (CBD) with two factors: (A) soaking time and (B) size of fruit pieces. Factor A consisted of 3 levels: A1 = 3 hours; A2 = 6 hours; A3 = 9 hours. Factor B consisted of 3 levels: B1 = 0.5×0.5×0.5 cm; B2 = 1×1×1 cm; B3 = 1.5×1.5×1.5 cm. The treatment was replicated two times. The analysis was antioxidant activity, vitamin C, pH, total flavonoid, and tannin content. The result showed a significant difference in soaking time on tannin content, vitamin C, pH parameters, and the size of fruit pieces on pH parameters. The best result was obtained in 1×1×1 cm of fruit pieces and 3 hours soaking time with 13.20 ± 0.01% vitamin C, 17.28 ± 0.83% tannin content, 0.107 ± 0.018 % flavonoid content, 92.56 ± 1.99 % antioxidant activity and 4.95 ± 0.03 pH value. This research provides data about the difference between soaking time and the size of fruit pieces to the pineapple-infused tea characteristic.
