Beras merupakan hasil pertanian yang banyak dikonsumsi oleh seluruh masyarakat di dunia. Di Indonesia, manajemen transparansi rantai pasok masih menjadi masalah utama karena belum tersedianya informasi yang dapat diakses seluruh anggota rantai pasok. Sangat sulit untuk mendapatkan informasi pada setiap aktor untuk keperluan pengawasan dimana hal ini menimbulkan risiko dan ketidakpastian. Ketelusuran menjadi kebutuhan penting untuk memastikan kualitas dan keamanan produk. Paper ini bertujuan untuk mengidentifikasi rantai pasok beras di Indonesia dan mengusulkan pemodelan sistem ketelusuran menggunakan Unified Modeling Language (UML). Hasil penelitian menunjukkan bahwa rantai pasok beras terdiri dari lima aktor yang berperan. Transisi keadaan dalam proses produksi dan informasi ketelusuran telah diidendifikasi melalui Critical Traceability Point (CTP) yang menyajikan informasi produk, kualitas produk, dan semua transformasi. Lebih lanjut, persyaratan kebutuhan fungsional sistem dan kebutuhan informasi disajikan dalam sequence dan uml static diagram. Terakhir, arsitektur sistem diuraikan dalam paper ini untuk mewujudkan transparansi serta pengendalian kualitas dan keamanan produk.

Kualitas beras adalah hal penting yang dipertimbangkan oleh konsumen ketika membeli beras. Kualitas meliputi beberapa aspek, antara lain kualitas mutu giling dan mutu tanak. Tujuan penelitian adalah untuk mengetahui kualitas beras yang dihasilkan oleh padi aromatik pada perlakuan lima taraf dosis pupuk nitrogen (N). Penelitian menggunakan rancangan acak kelompok petak terbagi untuk menguji pengaruh dosis dan varietas. Petak utama adalah pupuk nitrogen pada berbagai dosis, yaitu: 0, 45, 90, 135 dan 180 kg N ha-1, dan anak petak adalah dua varietas padi aromatik yaitu Sigupai Abdya (lokal Aceh) dan Inpari 23 Bantul (unggul nasional). Kualitas beras aromatik (mutu giling dan mutu tanak) pada penelitian ini tidak dipengaruhi oleh dosis pupuk nitrogen, tetapi hanya dipengaruhi oleh varietas. Berdasarkan mutu giling, varietas Sigupai Abdya memiliki rendemen beras giling dan beras kepala lebih tinggi serta persentase beras menir lebih rendah dibandingkan dengan varietas Inpari 23 Bantul. Berdasarkan mutu tanak, varietas Inpari 23 Bantul memiliki kandungan amilosa yang rendah, sedangkan waktu layak makan nasi lebih lama diperoleh pada varietas Sigupai Abdya.

Chili is one of the most important spices in Indonesia; the demand for chili is increasing along with the growth of the population. Chilli is generally grown under intensive culture which includes addition of fertilizers to improve crop growth and increase crop productivity. A study was conducted to examine seven different rates of an inorganic foliar fertilizer HF at 0.5, 0.75, 1, 1.25 and 1.5 of the recommended rate, with no foliar fertilizer and a standard foliar fertilizer GD as control. The results showed that spraying foliar fertilizer HF generally improved the growth and yield of chilli compared to without fertilizer. Plant height, number of branches and number of fruits per plant, weight per fruit, weight per 10 fruits, yield per plant, yield per plot, and yield per ha of chilli treated with inorganic fertilizers was significantly higher than the without foliar fertilizer. Foliar fertilizer HF at 0.5 of the recommendation rate, or 1 kg.ha-1 foliar fertilizer applied at 4, 6, 8, 10, and 12 week after planting in addition to the basic fertilizers of 400 kg.ha-1 of urea, 200 kg.ha-1 of SP-36, 250 kg.ha-1 of KCl applied to the soil, was effective to obtain the maximum chilli fruit yield.

[HUMIC COMPOUND APPLICATION FOR SOIL QUALITY IMPROVEMENT AND ENHANCEMENT OF PEPPER GROWTH]. Pepper (Capsicum Annum) is a strategic commodity that contributes to Indonesia's economy. The price of pepper fluctuates due to the instability of pepper production, which is influenced by multiple factors such as decreasing of soil fertility. Soil conditioner can help to improve soil fertility. The purpose of this research was to determine the effect of humic compounds application on pepper cultivation to improve soil fertility and increase the growth and yield of pepper. The research was conducted from February to August 2021 at the IPB Pasir Sarongge Experimental Field in Cianjur, West Java. The study was conducted using a Completely Randomized Group Design (CRGD) with one factor, humic compound solution concentrations of 0, 2.5, 5, 7.5, 10, and 12.5 mL/L, with each level repeated four times. Duncan's Multiple Range Test (DMRT) was used to separate the mean of the data after variance analysis. The result showed that humic compound application can improve soil fertility, growth and yield of pepper plants as indicated by increasing the value of Cation Exchange Capacity (CEC), decreasing potassium leaching rate and increasing all growth and yield characters except the yield per plant character. The application of 12.5 mL/L humic compounds increased CEC, decreased potassium leaching rate to 0%, increased plant height (37.40%), number of branches (56.72%) and number of fruits (57.81%). The application of humic compounds at 10 mL/L increases the weight of 10 fruits (30.78%), yield per plant (27.56%), yield per plot and predicted yield per hectare (47.58%).

The objective of the research was to study the nutrition uptake (nitrogen, phosphorus, and potassium,) and the grain production of five rice varieties representing modern, new plant type and local varieties under application of inorganic, organic and combined inorganic-organic fertilization. Five rice varieties were Way Apoburu and IR-64 (modern varieties), Midun and Sarinah (local varieties from Sukabumi and Garut, respectively), and Fatmawati (new plant type variety). Five fertilizer treatments were (1) full recommendation dosage of inorganic fertilizer (250 kg urea/ha, 100 kg SP-36/ha, and 100 kg KCl/ha), (2) ¼ recommendation dose of inorganic fertilizer + rice straw, (3) ½ recommended dose of inorganic fertilizer + rice straw, (4) rice straw, and (5) green manure from Crotalaria juncea biomass. The results showed that there was no specific response of rice varieties to the fertilization treatments, even though there was specific nutrient uptake pattern and yield of each variety, and there was significant effect of fertilizer treatment to nutrient uptake and rice yield. Nutrient uptake and grain yield indicated that nutrient imobilisation occurred at 1stseason, however the availability of N, P, K nutrients increased at 2nd and 3rdseason on rice straw and green manure treatments. Rice straw application caused lower nutrient uptake and grain yield than full dosage inorganic fertilizer at 1st season but both were not significantly different at 2nd and 3rdseason. Application of rice straw with ½ dosage of inorganic fertilizers was not significantly different from full dosage of inorganic fertilizers in nutrient uptake and grain yield. Modern varieties showed higher level of N absorption than that of new type variety although it was not significantly different with that of local varieties, whereas the P and K uptake of modern varieties was lower than that of local and new plant type varieties. The modern varieties also showed higher level of dry grain per hill than that of local and new plant type varieties. However yield per ha of all varieties tended to be similar. Key words: uptake, efficiency, mineral nutrition, variety, lowland rice

This experiment was conducted to determine the effect of plant growth regulator (Cycocel) and algifert in growth and bulb production of garlic (Allium sativum L.) cv. 'Lumbu Putih'. The experiment was set up randomized complete block design. Treatments were consisted of combination of algifert and cycocel applications. Algifert treatments consisted of spraying 0 (A0), 2 (A1), 4 (A2), 6 (A3) and 8 (A4) ml/l algifert solution on to garlic plants, while cycocel treatments consisted of spraying 0 (C0), 500 (C1), 1000 (C2) and 1500 (C3) Cycocel solution. Algifert spraying was conducted at 3, 5, 7, 9, 11 week after planting, while cycocel was at 8 week and 10 week after palnting. Result of the experiments indicated algifert and cycocel treatments did not significantly affect growth and bulb yield of garlic. However, interaction affect of algifert and cycocel significantly reduced total number of cloves of each garlic bulb. Comparation mean analyzis showed A2C3 (algifert 4 ml/l with cycocel 1500 mg/l) treatment resulted in significantly lower total number of cloves of each garlic bulb than A2C0 or A2C1 (algifert 4 ml/l with or with out cycocel 500 mg/l) treatments, respectively. Treatment combination A2C3 significantly reduced the total number of cloves each bulb. However, the reduction of total number of cloes was not followed by increased in the size of the cloves. The result of the experiment also indicated the presence of positive correlation among parameters recorded. The total weight of harvested biomass were positively correlated with diameter of the bulb, number of clove, dry weight of the bulb, and dry matter contain of the bulb, respectively.

There are two main problems when system of rice intensification (SRI) cultivation is carried out at tidal areas, e.g. the presence of Fe which is potentially toxic to plants and low nutrients availability. Utilization of Azotobacter-enriched compost is a choice to overcome iron toxicity as well a source of nutrients. The aims of this research were to study the effect of Azotobacter enriched compost to reduce the rates of inorganic fertilizers applied, to increase the efficiency of N, P, and K uptake, and to increase plant growth and yield. Two rice cultivation methods were applied namely SRI and conventional rice cultivation methods on tidal lands (rice fields) of South Kalimantan. A completely randomized block design with two factors was applied. The main plots were SRI and conventional rice cultivation, and as subplots were eight types of fertilizer that is a combination between Azotobacter-enriched compost with inorganic fertilizers rates. The results showed that soil nutrient availability, uptake and efficiency of N, P, and K with SRI technique was higher than conventional cultivation. Azotobacter- enriched compost on the tidal land (rice fields) could reduce the use of N and K fertilizer by 25%. Furthermore, the efficiency of N and P uptake in enriched compost with 75% of fertilizer N, P, and K were not different with enriched compost with 75% of fertilizer. Ciherang rice yields with SRI cultivation was approximately 22% higher compared to that from conventional rice cultivation. Keywords: Azotobacter-enriched compost, conventional rice cultivation, inorganic fertizers
