Abstract

The research objective was to analyse the financial aspect of the steamer rack type of oyster mushroom (Pleurotus ostreatus) baglog. The research was conducted from September 2011 to May 2012 at Kumbung jamur tiram, Talang Buruk Palembang. The methods used in this research were financial analysis that includes cost, the investment (NPV, Net B/C and BEP) and sensitivity analysis. The results showed that the average total cost per year was Rp. 20,724,527.00. The production plan was based on an assumption that 100% from selling price of oyster mushrooms Rp. 15.000,00 for one year was Rp. 26,775,000.00. NPV value was Rp. 11,875,188.00 representing the benefits value over the business life of 3 years. The B/C ratio calculation was 1.25. Break-even point (BEP) was on the price of Rp. 15.000 per kg or 1.381,63 kg of production volume. The results of sensitivity analysis of NPV values was obtained when 10% increase in production costs was Rp. 7,145,325.00 with B/C ratio of 1.13, whereas the value of NPV in 10% reduction of production costs was Rp. 5,957,814.00 with the B/C ratio of 1,12. The results of these research showed that the type rack of steamer oyster mushroom baglog was feasible.Keywords: mushroom steamer baglog, financial analysis, rack type  steamer, oyster mushroom

Abstract

Kegiatan pengabdian pada masyarakat di Desa Sukamulya Kecamatan Indralaya Utara Kabupaten Ogan Ilir Propinsi Sumatra Selatan. Adapun tujuan pengabdian kepada masyarakat tersebut antara lain :1. Memberikan informasi pengetahuan tentang cara memanfaatkan Ubikayu agar memiliki nilai tambah dengan cara mengolahnya menjadi Rengginang Ubikayu (untuk membedakan dengan Rengginang yang berasal dari Ketan atau Beras).2. memberikan kemampuan tambahan kepada masyarakat cara membuat rengginang sehingga dapat menjadi rintisan untuk industri kecil skala rumah tangga. 3. Menjadikan rengginang sebagai kegiatan yang menambah pendapatan rumah tangga.Kondisi Desa Sukamulya dilingkungi oleh kebun karet milik masyarakat desa tersebut sehingga aktifitas sehari hari sebagaian besar difokuskan pada usaha yang berkaitan dengan kebun tersebut. Mereka menanam ubi kayu (singkong) sebagai tanaman pekarangan, namun hanya dikonsumsi langsung saja, seperti direbus atau digoreng dan tidak ada pengolahan lanjutan. Dengan demikian melalui kegiatan pelatihan dan pendampingan masyarakat dapat mengolah Ubikayu menjadi Rengginang yang dapat dijual sebagai pendapatan tambahan. Hasil kegiatan ini, mereka menjadi antusias dan sangat tertarikakan pembuatan Rengginang sehingga mereka rela menyediakan waktu di sela-sela kegiatan mengolah tanaman karet untuk membuata Rengginang. Mereka membuat Rengginang baik untuk konsumsi sendiri maupun untuk dijual.

Abstract

Penggunaan alat pengering seperti cabinet dryer berbahan bakar minyak (BBM) atau gas (BBG) untuk pengeringan kerupuk kemplang merupakan solusi dalam mengatasi masalah pengeringan yang terkendala cuaca. Umumnya sistem pengeringan ini menggunakan udara panas sebagai medium pengeringan. Namun, pada penelitian ini akan dikembangkan sistem pengeringan kerupuk kemplang dengan menggunakan uap super panas. Penggunaan uap super panas untuk proses pengeringan didasarkan pada sifat termodinamika uap tersebut yang lebih unggul daripada udara pada kondisi yang sama. Rancangan alat pengering dengan uap super panas akan menggunakan sekam sebagai bahan bakar untuk pemanasan boiler. Berdasarkan uji teknis, perhitungan, dan uraian pembahasan yang telah dilakukan terhadap alat pengering kemplang tipe rak menggunakan uap kering super panas maka diperoleh suhu dan kelembaban relatif ruang pengering didapat sebesar 78oC dan 35%. Laju pengeringan rata-rata sebesar 7,01%/jam, kadar air akhir kemplang rata-rata sebesar 7%, dan kebutuhan energi panas total rata-rata 31.419,86 kJ. Efisiensi pengeringan dan efisiensi pemanasan dengan bahan bakar sekam adalah sebesar 7,41% % dan 2,07%. Alat pengering kemplang tipe rak menggunakan sumber panas uap kering super panas dapat diaplikasikan karena memenuhi karakteristik pengeringan.

Abstract

This study aims to apply image processing techniques in determining the level of fruit maturity based on color and the relationship of color changes with physical and chemical properties in Servo F1 varieties of tomatoes. This research has been conducted at the Laboratory of Agricultural Product Chemistry, Department of Agricultural Technology, Faculty of Agriculture, Sriwijaya University, Indralaya. This research was conducted from February 2019 until July 2019. This study used a descriptive method. The measured parameters are color, texture, moisture content, total sugar, and total acid. The results showed that the use of image processing methods can help the process of fruit sorting by looking at the relationship between the percentage of red color with the age of picking, the physical and chemical properties of the fruit. The percentage of tomato fruit red color on average ranged from 5.99% for picking age 25+1 days AFB (After the Flowers Bloom), 36.3% for picking age 29+1 days AFB, 67.41% for picking age 32+1 days AFB, and 76.85% for picking age 35+1 days AFB. The coefficient of determination of the relationship between the percentage of red color with the age of picking, texture, water content, total sugar, and total acid was 0.959, 0.908, 0.902, 0.835, and 0.750, respectively.

Abstract

This study aims to analyze the need for agricultural machinery to support a cropping index of 200 in swampy land. This research was conducted in August 2021 in Muara Abab Village, Rantau Bayur District, Banyuasin Regency, South Sumatra Province. This study used a descriptive-tabular method, while collecting primary data using survey techniques and semi-structured interviews. Secondary data collection was obtained through a literature study conducted to collect data on institutions and policies supporting the development of agricultural tools and machinery. The data obtained was processed descriptively and analyzed to see farmers income and the data is presented in the form of tabulations. The results showed that the total income of lebak swamp farmers was IDR 8,963,625.00/ha/year. To support the activities of the index cropping 200, it is necessary to add additional agricultural equipment such as 5 units of 2-wheeled tractors, 1 unit of 4-wheeled tractors, 9 units of water pumps, 5 units of combine harvesters, 14 units of threshers and dryer as much as 2 units.
