Abstract

The technology of cassava flour modification has been researched and developed. Biological change by using BIMO-CF containing lactic acid bacteria is a practical technology that is easy to apply in the production of cassava flour. This research was conducted from May until August 2017 at Agrosains Park Natar with the aim to know the chemical characteristics of cassava flour from Klenteng and Casessart varieties. Observation parameters included analysis of moisture content, ash content, fat content, protein content, fiber content, total carbohydrate content, starch content, HCN content, and white degree at THP Polytechnic State Laboratory of Lampung. The results showed that the highest yield was produced by cassava flour from casessart variety with the addition of BIMO-CF were 23.11%. The water content of cassava flour produced ranged between 8.02-9.19%, by the quality requirements of SNI. The lowest ash content was cassava flour from casessart variety (1.19%) without the addition of starter. The addition of starter increased the protein content of cassava flour both of Klenteng variety (0.47%) and Casessart variety (1.11%), decreasing the fiber content for Klenteng variety (0.67%) and Casessart variety (0.90%). The amount of fat contained in cassava flour produced ranged from 0.69 to 0.87%. Carbohydrate content (Klenteng variety was 88.49%, and Casessart variety was 87,69%) and starch content (Klenteng variety was 85,98%, and Casessart variety was 84,83%), cassava flour with the addition of starter higher than cassava flour without the addition of starter. All of the cassava flour produced has HCN levels below the maximum limit (0.0216-0.0293%), while the degree of white (> 80%) has not met the quality requirements of SNI.

Abstract

Cassava has been known to have low glycaemic index (GI) recommended for diabetics. Cassava can be used as alternative food source for substitution of rice as Indonesian staple food. The current study aimed to investigate phisycal and chemical properties of food diversification of cassava. Levels of dietary fibre were measured by enzymatic-gravimetric AOAC, while total sugar content was measured by Lane-Eynon titration. Determination of starch was observed by using spectrophotometer and energy analysis by bomb calorimetry. Level of glycaemic index (GI) was  determined by EL, S.N. method. The sensory analysis was performed by preference test by using hedonic scale towards 20 panelists. Analysis of cost and benefit was used to investigate the economic feasibility of the products. Among several products of cassava, analog rice has the highest value of dietary fibre (4.72%), starch (75.64%) and energy level (349.38 cal/kg).  In addition, it has the lowest value of total sugar content (1,19%) and GI (56).  It is also the most preferable in terms of colour (4.35), aroma (3.90), taste (4.35) and general acceptance (4.05). Economically, analog rice provides the highest profit than instant tiwul and oyek, which are 1.66; 1.56 and 1.47 respectively.

Abstract

Low production and low quality of vanilla caused by the farmers do not cultivate the plant in proper way, such as pruning the post, mound, fertilizer, and post harvest technology. Besides, monoculture farming system espesially for young plant caused does not have affort. The activity of assesment adaptability of package technology and farming system of vanilla was conducted at Jabung (East Lampung) in 2007. The treatments were Model 1 (recommended cultivation technology) such as superior variety of Anggrek vanilla, pruning the post, mound, and fertilizer, and Model 2 (traditional cultivation technology). Farming system of vanilla (vanilla-soybean and vanilla-chili) will be done by young plant of vanilla. The objective was to increase farmers income and to obtain technology packages cultivation and farming system exspecially for young plant of vanilla. The result showed that cultivar Anggrek vanilla that support by application of recommended cultivated technology such as prunning andfertilizer produced higher growth than local cultivar. Soybean and chilli were planted among vanilla result the same growth and production with soybean monoculture and chilli monoculture. Soybean planted among vanilla (pattern of vanilla-soybean) increased farmers income average Rp.1.691.000,- per ha per season (3 months) and increased farmers income average Rp. 1.656.000,- per ha per season (3 months) by pattern of vanilla-chili.

Abstract

Salah satu strategy untuk mempertahankan swasembada beras adalah melaksanakan program SLPTT dengan sasaran meningkatnya kualitas teknik budidaya, intensitas tanam dan produktivitas padi. Pengkajian ini dilakukan pada lokasi SLPTT di Kabupaten Pesawaran, Lampung dari bulan Mei sampai September 2010. Jumlah sampel yang yang diamati 180 unit terdiri 60 unit lokasi SLPTT LL VUB, 60 unit lokasi SLPTT LL non VUB dan 60 unit lokasi non SLPTT. Pada lokasi SLPTT LL VUB diterapkan model PTT seperti verietas unggul baru (Inpari 1, Inpari 7, Inpari 9 dan Cigeulis), sistem tanam jajar legowo (2:1 dan 3:1), rekomendasi pemupukan spesifik lokasi (sesuai PerMentan), dan model sekolah lapang (SL). Pada lokasi SLPTT non VUB diterapkan penggunaan Ciherang dan dosis petani setempat (SK Bupati), sedangkan pada lokasi non SLPTT disesuaikan dengan kebiasaan petani. Data yang dikumpulkan antara lain biaya produksi, komponen hasil, dan masalah-masalah yang timbul. Hasil kajian menunjukkan bahwa produktivitas rata-rata padi sawah pada lokasi SLPTT LL VUB adalah 6.737 kg/ha, SLPTT non VUB 7.174 kg/ha dan non SLPTT 4.587 kg/ha. Penggunaan VUB meningkatkan produktivitas sebesar 8,85% dibandingkan dengan SLPTT non VUB dan 47,13% dibandingkan dengan lokasi non SLPTT. Rata-rata pendapatan usahatani padi pada lokasi SLPTT LL VUB adalah Rp.17.410.000,-/ha (R/C=3,15), lokasi SLPTT LL non VUB Rp. 13.488.806,-/ha (R/C=2,46) dan lokasi non SLPTT Rp.9.885.625,-/ha (R/C=2,34). Melalui penerapan VUB pada lokasi SLPTT mampu meningkatkan pendapatan petani sebesar 29,07% sampai 76,12%.
