Abstract

Komoditas bawang merah merupakan komoditas dengan permintaan yang cukup tinggi di Indonesia. Rata-rata konsumsi bawang merah per kapita sebesar 0,54 ons per hari. Sebagai komoditas sayuran bawang merah termasuk komoditas dengan produksi tinggi sebesar 1.49 juta ton pada tahun 2018. Sentra usaha bawang merah di Lampung masih dalam pengembangan untuk membantu menstabilkan kebutuhan suplai bawang merah dan menjaga kestabilan harga di pasar.  Penelitian ini bertujuan untuk mengetahui manfaat  serta kelayakan dalam aspek teknis, finansial dan sosial ekonomidalam usaha tani bawang merah. Penelitian ini dilaksanakan di salah satu kawasan lahan pertanian bawang merah di Lampung Tengah kecamatan Kota Gajah. Metode yang digunakan meliputi wawancara langsunguntuk pengumpulan data primer dan pengumpulan data sekunder melalui pusat informasi daerah.Penilaian secara finansial menggunakan analisis kriteria investasi nilai NPV, IRR, rasio pendapatan dan biaya (revenue and cost ratio). Hasil analisis teknis menunjukkan bahwa daerah kecamatan Kota Gajah memiliki iklim, jenis tanah dan ketersediaan serta skill petani yang memenuhi untuk tanaman bawang merah. Pada analisis finansial menunjukkan usaha tersebut layak dijalankan karena  diperoleh rasio revenue dan cost sebanyak 1,8, dengan nilai NPV Rp. 16.343.200.177,00 dan IRR 15,19% pada periode kedua diatas tingkat diskonto. Pada aspek sosial ekonomi menunjukkan bahwa tanaman bawang merah mampu meningkatkan penghasilan petani sebanyak 4 kali lipat dibanding menanam padi serta membuka hubungan kerjasama dengan berbagai pihak baik pemerintah, swasta dan petani di luar kecamatan Kota Gajah.

Abstract

Siam juice contain limonin and naringin that produce a bitter taste although these compounds useful  as an antioxidant and anticancer. Bitter taste in juice is unfavor for consumer. The purpose of this research was to find the best conditions in reducing bitter taste in Siam juice by using cyclodextrin and cellulose acetate. These research performed at variation of mixing temperature  (27; 60 and 80ºC), cyclodextrin concentration (0.1; 0.3 and 0.5% (w/v)) and cellulose acetate ( 0.2; 0.4 and 0.6% (w / v)). The results showed that the use of cyclodextrin and cellulose acetate were able to trap limonin and naringin. The higher reducing limonin juice was 91.57% by addition cyclodextrin 0.1% at 60ºC, whereas for naringin obtain by addition cellulose acetate 0.5% at 79.69% . At this temperature, the juice quality (vitamin C) can be maintained.

Abstract

Feed laboratory is a facility that guarantees feed quality in the feedlot industry. But the existence of this laboratory has not been fully considered both in terms of facilities and layout that ease the movement of workers. This research aims to analyze machine and raw material properties in the feed laboratory, to find total closeness rating between facilities according the need and designing the layout of facilities in the laboratory that can streamline the material flow. The problem is how to design facility layout in feed laboratory which has different tool and machine characteristics in limited space, how to plan material flow that can minimize work flow. The method used is computerized relationship layout planning (CORELAP). The result obtained is the design of the laboratory layout by comparing the optimum distance on the inter-work track. The calculation value from allocation relationship diagram showed the biggest total closseness rating is the testing room. From the calculation of the distance difference layout design, it is known that the second alternative provides a better solution with the largest distance difference of 41.52 for space with condition should be close and the distance difference of -31.21 for space with the condition should not be close.

Abstract

Shallot is superior vegetable commodity in which the demand has a tendency to increase. The growth of demand for commodity is in line with the growth of population in Indonesia. Shallot is included in 7 (seven) basic foodstuffs targeted by Ministry of Agriculture in Indonesia. The need of shallot is supplied by Central Java, East Java, West Java and West Nusa Tenggara. Shallot commodities in Indonesia heavily depend on the season, the government makes a regulation about shallot import for maintaining stability of price. To anticipate the occurrence of imports, the government is focused on inviting local governments to create a farming center of shallot. Lampung Province is one of the provinces that has suitable natural resources for shallot farming. The purpose of this research is to analyze the financial feasibility of shallot farming development based on NPV (Net Present Value), Net B/C (benefit/cost), IRR (Internal Rate Return), and payback period criteria. The financial feasibility analysis through the calculation of cost and benefit components obtained from shallot business and investment criteria to determine the level of feasibility in quantitative terms. The result showed that NPV is IDR. 16,747,507.38, Net B/C 1.45, IRR for 4 period is 66.03% and payback period is 3.58.

Abstract

Management of feedlot manure is becoming a larger responsibility as more regulations are imposed to protect water, both surface and groundwater, from manure contamination. Instead of using the manure for compost, feedlot owners can capture methane from the decomposing manure (and turn that into electricity or heat), or use the waste to produce liquid fuel. Biogas may also be called renewable natural gas because biogas can be used as a fuel source to produce electricity and heat like natural gas.This research converting energy generated from the measurement of total waste theoretically to be convert to electricity generated from the waste. Within the number of 19,398 total cows in Jati Agung Sub District husbandry has the potential to produce electric energy of 149,365.376 kwh per day or 15,836.79 mwh per year. The conversion from waste to electricity will reduce the number of total emission of 64,086.7464 tCO2 per year.

Abstract

Pendekatan joint replenishment merupakan salah satu metode yang digunakan dalam melakukan replenishment inventori. Dengan joint replenisment. Dengan joint replenishment biaya pesan dapat diminimasi karena hanya menggunakan satu kali pengiriman untuk beberapa produk sekaligus. Contoh proses replenishment inventori yang menggunakan pendekatan ini adalah pada retailer maupun toko grosir dengan jenis produk consumer goods. Ciri dari pasar consumer goods adalah adanya kemungkinan pemenuhan demand dengan produk lain yang sejenis, sehingga dapat dikatakan produk tersebut dapat saling mensubstitusi. Selain itu, terdapat kesulitan dalam proses replenishment produk jenis ini yaitu adanya ketidakpastian demand dari sisi customer. Penelitian ini mengembangkan model inventori Maddah, dkk (2016) mengenai model joint replenishment dengan mempertimbangkan substitusi produk. Pada penelitian ini, digunakan demand dengan sifat probabilistic. Service level telah ditetapkan sebelumnya oleh perusahaan (probabilistic sederhana). Ukuran kinerja yang diperhatikan adalah meminimasi ongkos total yang terdiri dari ongkos pembelian, ongkos pemesanan, ongkos penyimpanan, dan ongkos kekurangan. Berdasarkan uji coba model, didapati hasil bahwa model joint replenishment dengan substitusi memberikan ongkos total lebih rendah dibandingkan tanpa substitusi. Selain itu, model tersebut juga sensitif terhadap perubahan harga dan perubahan ongkos simpan.
