Paraffin is a problem commonly faced in petroleum production. The presence of paraffin can inhibit the process of oil flow. Mitigation methods commonly used to overcome this problem is by using chemical injection, which is solvent. In this research, a laboratory experiment was conducted to make bioethanol from agricultural waste that are rice husks and corn cobs. This bioethanol functions as a solvent that is used to reduce the pour point in a waxy-paraffinic crude oil sample. Oil samples were mixed with bioethanol with different mixing ratios, including 5%, 10%, 15%, 20% 50%. The results showed that the alcohol content of the Husk and Corncob rise was 11% and 9% respectively. Then, the best result from mixing of bioethanol with oil reduced the pour point from 43.3 to 41 at mixing ratio of 50%.
Ikan Patin (Pangasius pangasius) saat ini merupakan komoditas perikanan air tawar yang cukup digemari dan memiliki nilai ekonomi yang relatif tinggi di Indonesia. Permasalahan yang dihadapi dalam budidaya ikan Patin adalah pertumbuhannya yang lambat. Penambahan rGH menjadi salah satu teknologi yang dapat membantu pertumbuhan ikan. Tujuan penelitian ini adalah mengetahui pengaruh pemberian Recombinant Growth Hormone (rGH) melalui metode oral dengan interval waktu berbeda terhadap pertumbuhan panjang mutlak, pertumbuhan berat mutlak, laju pertumbuhan spesifik, rasio konversi pakan dan kelangsungan hidup ikan Patin (Pangasius pangasius). Metode penelitian yang digunakan yaitu, Rancangan Acak Lengkap (RAL) yang terdiri dari 5 perlakuan dan 3 ulangan dengan dosis penambahan rGH 2 mg/kg pakan. Perlakuan yang diberikan yaitu pakan tanpa rGH (P0); pakan dengan tambahan kuning telur (P1); pakan yang mengandung rGH dengan interval waktu pemberian 3 hari (P2); 4 hari (P3); dan 5 hari (P4). Hasil penelitian menunjukan bahwa pemberian pakan yang mengandung rGH dengan interval waktu 3 hari menunjukan hasil yang terbaik, dengan nilai pertambahan panjang mutlak 1,31±0,05 cm, pertambahan berat mutlak 5,17±0,03 gr, laju pertumbuhan spesifik 2,61±0,01%, rasio konversi pakan 1,06±0,01, dan kelangsungan hidup 90,00±0,00%. Kesimpulan dari penelitian ini adalah pemberian Recombinant Growth Hormone (rGH) melalui metode oral dengan interval waktu berbeda berpengaruh nyata terhadap pertumbuhan panjang mutlak, pertumbuhan berat mutlak, laju pertumbuhan spesifik, dan rasio konversi pakan. Namun tidak berpengaruh nyata terhadap kelangsungan hidup ikan Patin (P. pangasius).
In the first quarter of 2022 (1 January – 31 March) in Indonesia, there are problems related to the increase in the prices of basic necessities which can increase the amount of initial capital needed in a milkfish (Chanos-chanos) cultivation business. So it is necessary to conduct an initial simulation study of the feasibility analysis of milkfish cultivation to determine the capital and business feasibility for milkfish cultivation in the first quarter of 2022. The method used in this study is a library research method, where the data collection method is entirely with data. Secondary or literature study. Secondary data is collected by reviewing from references in the form of journals, books, and online articles that are still related. The calculation of business feasibility analysis is carried out by calculating investment costs, fixed costs, variable costs, calculating production costs, revenues, profits, BEP Rupiah, BEP Units, R/C Ratio, and PBP. Furthermore, an analysis of the supporting and inhibiting factors of the business as well as an analysis of the marketing strategy in the milkfish cultivation business was carried out. The results of the calculation of business feasibility simulations show that the production cost is Rp. 78.276.800, revenue is Rp. 1.344.000.000, profit is Rp. 950.861.600, Rupiah BEP is Rp. 192.549.566, which means the turning point will be achieved if sales reach Rp. 192.549,566. , BEP Unit is 9627 fish, which means the turning point will be reached if milkfish production reaches 9,627 fish. The R/C Ratio obtained is 1.7 and the PBP is 0.3 years, where the investment capital of this milkfish cultivation business will return within a period of 0.3 years or 3.6 months. Therefore, the milkfish cultivation business for the first quarter of 2022 can be said to be profitable and feasible to run.
Banyumas memiliki kerajinan produksi batik yang sangat menjanjikan dan mulai dikenal di pasar nasional. Tercatat darah penghasil batik di Banyumas terdiri di daerah Sokaraja, Meruyung, Kebasen dan Purwokerto. Pengrajin batik rumahan tersebut menjual batiknya ketempat pemasaran yang berada dibawah UKM Batik Blakasutha, Banyumas. Tujuan kegiatan ini adalah penanggulangan dan pengurangan produksi limbah produksi batik. Metode pendekatan yang dilakukan dalam kegiatan ini adalah pendekatan Particiatory Action Learning System (PALA). Pendekatan ini dimaksudkan agar mitra sasaran dapat saling terbuka dan berbagi cerita tentang permasalahan serta harapan pada usaha kelompok yang dijalaninya. dalam upaya untuk meminimalisir dan/atau menangani permasalahan yang dihadapi mitra, maka dilakukan rangkaian kegiatan yang meliputi: Survey pendahuluan dan identifikasi permasalahan, Kegitan pendampingan dan pembinaan, Pelatihan dan pendampingan pembuatan pewarnaan alami menggunakan tanaman indigofera. Pelaksanaan pengabdian dilakukan pada bulan Maret-September 2021. Pengabdian ini menghasilkan peningkatan pengetahuan tentang penggunaan pewarnaan alami untuk batik serta diversifikasi motif/pola batik ikan. Program pengabdian ini juga membantu dalam pemasaran produksi batik.
