Abstract

Kalium merupakan salah satu hara makro primer bersama hara N dan P, yang dibutuhkan tanaman dalam jumlah yang banyak. Kekurangan hara K salah satunya dapat menyebabkan transportasi fotosintat ke biji tidak lancar atau terhambat. Ketersediaan hara K dalam tanah sawah bervariasi yang tergantung pada sifat kimia tanah yang lain. Makalah ini bertujuan untuk mengevaluasi karakteristik hara K tanah sawah, sumbangan hara K dari air irigasi dan jerami sisa hasil panen, serta respon pemupukan terhadap hasil padi. Ketersediaan hara K, selain dipengaruhi komposisi mineral liat, kandungan liat, C-organik dan KTK tanah, juga dipengaruhi oleh pemupukan N, pH tanah, Ca dan Mg-dd serta N-total. Kandungan K potensial dan K-dd semakin meningkat pada lahan sawah terutama di Pulau Jawa bagian timur karena mempunyai tanah dengan bahan induk kaya mineral kalium. Kandungan K-dd sangat erat hubungannya dengan K potensial dengan R2 = 0,53 (n=73). Berdasarkan peta status hara K Lahan sawah skala 1:250.000 di 23 provinsi di Indonesia, diketahui bahwa sebagian besar lahan sawah berstatus K sedang 37% dan tinggi 48%. Kadar K dalam tanah sawah yang berasal dari air irigasi sebesar 7-74 kg K/ha/musim. Jika semua jerami padi sisa hasil tanaman dikembalikan ke lahan, kebutuhan hara K untuk tanaman padi sudah tercukupi terutama pada sawah berstatus hara K sedang dan tinggi. Respon pemupukan K pada tanaman padi akan terlihat nyata apabila tanah mengandung K-dd < 0,10 cmol(+)/kg. Implikasi kebijakan dari makalah ini adalah bahwa pemupukan K dapat difokuskan pada lahan sawah dengan kandungan K rendah, efektivitas pemupukan K dapat ditingkatkan dengan pengembalian jerami padi sisa hasil panen dan pemupukan N yang tepat.

Abstract

Serai merupakan bahan baku untuk produksi minyak serai. Indonesia masuk dalam sepuluh negara terbesar produsen minyak serai di dunia. Industri pengolahan minyak serai akan menghasilkan limbah serai. Penelitian ini bertujuan untuk mengetahui pengaruh subtitusi rumput gajah (Pennisetum purpureum) dengan limbah serai terhadap fermentasi rumen secara in vitro. Penelitian ini menggunakan rancangan acak kelompok dengan 5 perlakuan (100R: limbah serai 0%, 75R: limbah serai 25%, 50R: limbah serai 50%, 25R: limbah serai 75%, 0R: limbah serai 100%) dan 4 waktu pengambilan rumen yang berbeda sebagai kelompok. Hasil penelitian menunjukkan bahwa substitusi rumput dengan limbah serai tidak memberikan perbedaan yang signifikan terhadap kadar bahan kering, namun dapat menurunkan kadar protein dan meningkatkan serat kasar serta lemak kasar secara signifikan (P<0,05). Hasil analisis keceranaan in vitro terhadap aktivitas fermentasi rumen, menunjukkan bahwa substitusi serai tidak mempengaruhi pH, kecepatan produksi gas, asam butirat, asam valerat, asam isobutirat, dan asam isovalerat baik dari segi jumlah maupun proporsi. Substitusi rumput dengan limbah serai sebesar 25% (75R) tidak menghasilkan penurunan kadar bahan organik, produksi gas potensial dan produksi metan (jam ke-24) namun terjadi penurunan kadar protein dan meningkatkan lag time secara signifikan (P<0,05). Penggunaan serai sebesar 50% dapat menurunkan produksi gas metan secara signifikan (P<0,05). Peningkatan konsentrasi limbah serai yang digunakan menyebabkan terjadinya perubahan profil VFA parsial yang disebabkan oleh adanya perubahan komposisi asam asetat. Penurunan rasio asam asetat/ propionat (A/P) secara signifikan terjadi pada penggunaan serai sebesar 100%. Penggunaan limbah serai dapat mensubtitusi rumput gajah hingga 25% pada pakan tinggi hijauan tanpa terjadi penurunan pada produksi gas potensial, kecernaan dan total VFA.

Abstract

Imported soybeans have dominated national soybeans for more than two decades. To reduce dependence on imported soybeans, efforts are needed to maximize national soybean production and productivity through technological innovation. Soybean high yielding varieties are one of the easiest technologies to be adopted by farmers. The assessment aims to evaluate perceptions, attitudes and satisfaction of farmers with the attributes of superior soybean varieties. The assessment was carried out using a survey method of soybean farmers totaling 32 people in The Kebumen Regency. High yielding soybeans varieties studied is Grobogan, Anjasmoro and Gema varieties. Attributes evaluated are plant performance, yield, soybeans price selling, easier seeds to obtain, harvest age, the suitability of seed size to demand and pest resistance. Farmers’ perceptions were mapped using perceptual mapping, farmer attitudes were analyzed using the Fishbein Multiattribute Model and farmer satisfaction was analyzed using the Customer Satisfaction Index (CSI). The results of the study showed that farmers had better perceptions, attitudes and satisfaction towards Grobogan and Anjasmoro varieties compared to Gema variety. Grobogan and Anjasmoro varieties were perceived as more excellent because they had more attractive plant diversity, higher production, easier seeds to obtain and more resistance to pests-diseases. Farmers showed a more accepting attitude to cultivating Grobogan and Anjasmoro varieties with Fishbein Multiattribute scores of 45.63 and 43.93, while the Gema variety only scored 39.64. Farmers have a higher level of satisfaction with Grobogan and Anjasmoro variety with CSI values of 52.11% and 50.37% compared to the Gema variety of 44.66%.

Abstract

Potato self-sufficiency in Indonesia faces three main problems: rising air temperatures, limited availability of low-temperature land suitable for potato cultivation, and lack of high-temperature tolerant potato varieties. Therefore, it is necessary to identify the tolerance of potato variety to high-temperature. This research was conducted in two locations: the optimum temperature location and the high-temperature location, using nine varieties, are Agria, Andina, Amabile, Cingkariang, Granola L, Granola K, Margahayu, Olympus, and Tedjo-MZ. The study design uses a split plot with three replications. Differences in temperature as the main plot and varieties as subplots. Parameters observed were air temperature, growth, and yield of potato tubers. The analysis carried out were the Stress Sensitivity Index (SSI), Stress Tolerance Index (STI), Yield Stability Index (YSI), and Cluster Analysis. The results showed that there were no tolerant to high-temperature varieties. Based on the STI, only Olympus was a medium tolerant of high temperatures. Based on the Stress Sensitivity Index (SSI), four varieties are moderately susceptible to high temperatures (Olympus, Andina, Cingkariang, and Margahayu). The YSI analysis shows the same results as the SSI. The cluster analysis results showed harmony between the results of the stress index analysis and cluster analysis. Nine varieties had a high similarity (87.3%), meaning that all varieties had the same characteristics and less tolerance to high temperatures. Olympus was the more tolerant variety to high temperatures, followed by Andina, Cingkariang, and Margahayu. The four varieties consider promising potato lines in high-temperature areas.

Abstract

Soybean is planted in some types of land agroecology, but production centers are mostly on peat and tides. This research was conducted at the soybean center in Rantau Rasau District with agroecology peat and tideland. The trial was arranged in a Randomized Block Design (RBD) with ten treatments and four times repeatitions. It consisted of several doses of organic material decanter cake (DC) and the percentage of the recommended amount of mineral fertilizer (RDF). RDF was selected based on Indonesia Food Crop Agriculture Service. Decanter cake from palm oil mill waste was used as a source of organic material. Experimental parameters are plant height, leaf number, grain yield, 100 grain weight, and the number of pods, seeds per pod, and plant. The result indicated the combination of mineral fertilizer and organic material DC had significant differences in increasing plant height and number of leaves. Different types of RDF and DC combinations showed substantial effects on the soybean yield and yield components. The combination of RDF 25% and decanter cake at any dose positively impacted soybean height, leaf number, and grain yield component. The highest dry seed yield of 2.48 tons per hectare was achieved by a combination of 25% RDF and 20 ton ha-1 decanter cake. Soybean yield in this study was higher than Anjasmoro’s description of 2.03–2.25 tons ha-1

Abstract

Artemisia is one of the plants that can be used as an alternative medicine for malaria. The Artemisia plant contains secondary metabolites in the form of artemisinin compounds that function as antimalarials. One of the efforts that can be done to increase the growth of Artemisia annua. plants is by using a growth regulator of gibberellins (GA3). Using a Randomized Block Factorial Designs (RBFD) with the first factor being the concentration of 50 mg.L-1 (K1), mg.L-1(K2), 150 mg.L-1 (K3), 200 mg.L-1 (K4). The second factor has 3 frequencies, 1 time giving 7HSPT (F1), 2 times giving 7HSPT and 14HSPT (F2), and 3 times giving 7HSPT, 14HSPT and 30HSPT (F3). In addition, there were plants that were not given GA3 control (without treatment). Parameters observed were plant height, leaf area, glandular trichome density, and plant dry weight. The results showed that the administration of gibberellins (GA3) with different concentrations and frequencies on plant height, leaf area, glandular trichome density, and dry weight of A. annua plants had no significant effect. Plants have not been able to grow properly because the provision of gibberellins that have not been active stimulates all plant tissues and directly seeps through the roots, stems and leaves.

Abstract

The purpose of this study is to determine the characteristics of shallot cultivation and to understand the financial feasibility analysis in Dolok Silau Simalungun to enhance the improvement of the technology needed. Methods used in this research are survey and observation methods. Based on the assessment results, it was found that shallot farming which is planted on dry land and small scale in Sarang Padang, Dolok Silau, Simalungun has a 0,05 – 0,1 ha area. The productivity of that farming is low which averaging 5,25 tonnes/ha. The total production cost is Rp 59.598.000 with a B/C ratio of 0,59. The capital of shallot production is Rp 10.743,00 per kg. Most of the shallot production cost is absorbed by labor cost (36 %), followed by seed cost (35%). The increment of revenue can be achieved by improving productivity through the improvement of farming technologies. Technology improvements in shallot cultivation that are needed are increasing plant density, seed quality improvement, replacement of labor weeding, and the use of integrated pest and disease control. To anticipate price fluctuations, farmers need a storage technology that is a group warehouse to keep the shallot when the market price is very cheap. Institutional education needs to be strengthened for the socialization of shallot cultivation technology and innovation for the farmers.
