Study on effects of cow manure rates and fermentation periods on quality of Arabica coffee was carried outin Belantih Village, Kintamani District, Bangli in 2002-2003. The experiment used a randomized split block designwith two treatments and each of four replications, namely cow manure rates (P) and fermentation period (F). Therewere 6 levels of P treatment, namely 5, 10, 20, 30, 40, and 60 kg/tree/year. F treatment consisted of 4 levels, namely12, 24, 36, and 48 hours. Combination of two treatments improved significantly physical quality, except the beans ofL size and all components of coffee tastes. Cow manure of 5 kg/tree/year and fermentation periods of 12 to 24 hourswere able to produce quality beans and good coffee taste. Cow manure rate of 5 kg/tree/year with fermentation periodof 24 hours produced highest M-size beans (18.43%), with lowest Ss-size beans (10.07%). Best coffee aroma wasfound in manure rate of 5 kg/tree/year with fermentation period of 12, 24, and 36 hours. Flavor scores of manure rateof 5 kg/tree/year with all fermentation periods, except that of 48 hours, were higher than those of 60 kg/tree/year.Highest strength (7.30) was found on the rate of 5 kg/tree/year with 24 hour of fermentation. Acid or bitter taste waslower on the coffee tree at applied with 60 kg/tree/year than that applied with 5 kg/tree/year. Lower rate of manureapplication was able to produce optimal quality coffee beans than that applied by the farmers, namely 60 kg/tree/year.Key words: cow manure, coffea arabica, fermentation, physical quality, flavor, Bali.Penelitian mengenai pengaruh dosis pupuk kandang sapi dan lama fermentasi terhadap mutu hasil KopiArabika telah dilakukan di Desa Belantih, Kecamatan Kintamani, Bangli pada tahun 2002-2003. Rancanganpercobaan yang digunakan dalam penelitian adalah Rancangan Acak Kelompok Faktorial dengan dua perlakuan, yaitudosis pupuk kandang (P) dan lama fermentasi (F). Perlakuan dosis pupuk kandang (P) terdiri dari enam level, yaitu :5, 10, 20, 30, 40, dan 60 kg/pohon/tahun. Perlakuan lama fermentasi (F) terdiri dari empat level, yaitu : 12, 24, 36, dan48 jam. Fermentasi dilakukan dengan cara basah terhadap biji kopi yang telah dikupas. Perlakuan dilakukan empatkali ulangan. Untuk mengetahui beda antarperlakuan digunakan uji DMRT. Secara statistik, kombinasi keduaperlakuan, yaitu dosis pupuk kandang dan lama fermentasi berpengaruh nyata terhadap semua komponen mutu fisikkopi, kecuali jumlah biji ukuran L dan semua komponen citarasa kopi. Secara umum, pemupukan dosis 5kg/pohon/ tahun dengan kombinasi lama fermentasi 12 jam sampai 24 jam sudah dapat menghasilkan biji KopiArabika Varietas S 795 dengan mutu fisik yang baik dan dapat menghasilkan seduhan kopi dengan mutu citarasa yangbaik pula. Dosis pupuk 5 kg/pohon/tahun dengan lama fermentasi 24 jam menghasilkan jumlah biji ukuran M tertinggi(18,43 %) dengan jumlah biji ukuran Ss terendah (10.07%). Aroma kopi terbaik (skor 7,00) diperoleh pada perlakuandosis pupuk 5 kg/pohon/tahun dengan lama fermentasi 12, 24, dan 36 jam. Skor perisa pada perlakuan dosis pupuk 5kg/pohon/tahun dengan semua perlakuan lama fermentasi, kecuali 48 jam lebih tinggi dibandingkan skor padaperlakuan 60 kg/pohon/tahun. Demikian juga dengan dosis pupuk 5 kg/pohon/tahun dengan lama fermentasi di atas 24jam memberikan skor kekentalan tertinggi (7,30). Namun, untuk keasaman dan rasa pahit, dosis pupuk 60kg/pohon/tahun memiliki skor yang lebih rendah dibandingkan dosis 5 kg/pohon/tahun. Rasa asam atau pahit yangterlalu tinggi tidak dikehendaki dalam citarasa kopi. Berdasarkan keunggulan mutu fisik dan citarasa kopi yangdihasilkan, aplikasi pupuk kandang yang lebih sedikit namun dapat menghasilkan produk dengan kualitas yangoptimal ini dapat menggantikan dosis pupuk kandang yang selama ini diterapkan oleh petani, yaitu 60 kg/pohon/ tahun.Kata kunci: pupuk kandang, Coffea arabica, fermentasai, mutu fisik, citarasa, Bali

Article 1 (3) of the Government Regulation 69 of 1999 on Food Labels and Advertising is meant to determine that food labels are : every description of food in the form of drawing,writings, a combination of both or any other form supplied with food, put in, affixed to or a part of food packinging. From the above definition, label can be seen that the information contained on the label. The absence of correct information, clear and honest that should be listed in the labels could mislead consumers and course the legal consequances on actors in the business to be responsible if to harm consumers. It is interesting to examine whether the labeling of food products as stipulated in Government Regulation 69 of 1999 has beed compliance with theprinciples of consumer protection.

A study was conducted during two planting seasons, namely planting season 1 (PS-1) 2017/2018 and (PS-2): 2018/2019, in Oelnasi Village, Central Kupang sub-district, Kupang District, East Nusa Tenggara, Indonesia. This study aimed to evaluate the rotation pattern of maize with legumes ground covers towards the dynamics of soil carbon and nutrients N, P, K during the two growing seasons in a dryland farming system. The experiment was designed using a randomized block design with 3 (three) treatments replicated five times. The treatments evaluated were: crop rotation patterns consisting of: without rotation (farmer practice) and rotation pattern with Phaseolus lunatus; rotation pattern with Mucuna pruriens. Legume crops planted after harvesting the food crop and allowed to grow during the dry season. Approaching the rainy season, the biomass of the legume crop is returned to the land by immersing them it together with soil cultivation. Chemical fertilizers is given as an independent variables with a dose of 150 kg/ha of Urea; 100 kg/ha of SP36 and 100 kg/ha of KCL. The results showed that the rotation pattern of Mucuna pruriens significantly increased the soil organic C content by 50.56% and legume Phaseolus lunatus by 37.64% to PS-2. The rotation pattern of the legume covers / covered crop also significantly increased the efficiency of agronomic nutrients (N, P, and K nutrients) and maize yields during the two growing seasons. On the other hand, the farmer pattern (without rotation) showed a decrease in soil carbon to PS-2 which of course affect the efficiency of nutrient absorption.

The experiment was conducted in the field at dryland farming areas at Cengiling village, Jimbaran, district of South Kuta, Badung (50 m asl), from 9 March until 3 June 2008. The objective of the experiment was to study the effects of plant population on grain yield, and forage production of corn varieties, plantedat the end of rainiy season. A randomized complete block design was used in this experiment, in which treatments were arranged factorially. The treatments were plant population (71,428; 142,857; 214,284 and 285,712 plants ha-1 or one, two, three and four plants hole -1), and corn varieties (BISI-2, CPI-2, Srikandi Putih and Local Bukit). All treatments were replicated three times. Results of the experiment indicated that interaction effects between plant population and variety were significant on grain yield and straw quality of corn. Variety of Local Bukit at population of 285,712 plants ha-1 resulted in the highest grain yield at 12% moisture (9.39 t ha-1), and grain oven dry weight (6.28 t ha-1). ). That variety at that population gave higher forage crude protein (7.66%) than that given by variety CPI-2 but was not significantly different from that given by BISI-2 and Srikandi P. The variety of Local Bukit at that population also resulted in lower forage crude fiber (18.16%) than the value given by the other varieties. The highest population resulted in the highest fresh and oven dry weights (22.76 dan 14.36 t ha-1) of forage. Variety of Local Bukit and BISI-2 gave higher (12.39 and 14.01 t ha-1) oven dry weights than the other varieties. In this experiment the optimum plant population for maximum grain yield and quality of forage for each corn varieties had not been obtained.

Water availability is a major limiting factor to the growth and yield of rainfed rice. Systemof Rice Intensification (SRI), which is an efficient method of planting rice, particularly inthe use of water, number of seeds per hill and time of transplanting seedlings, has beenapplied generally in irrigated rice but it is rarely practiced in rainfed rice.A field experiment, which was aimed to study the effect of number of seed/hill and variationof plant spacing on the growth and yields of rainfed rice with SRI (System of RiceIntensification), was conducted during dry season from April until September 2012. Thelocation was at Patemon Village, District of Seririt, Buleleng Regency, Bali, at the altitudeof 100 meter asl. In this experiment a completely randomized block design was used and thetreatment were arranged factorially. The first factor was the number of seeds (1,2,3 and 4)/hill and the second one was the plant spacing (20 cm x 20 cm, 25 cm x 25 cm and 30 cm x 30cm). All treatments were replicated three times.The results of the experiment showed that the interaction between one seed/hill and plantspacing of 30 cm x 30 cm resulted in significantly (P<0.05 and P<0.01) the highest fresh(4.387 ton/ha) and oven dry weight of grains (3.633 ton/ha), oven dry weight of 1000grains (20.920 g) and the harvest index (31.163%). The gross margin analysis indicatedthat the variable costs were higher than the gross income for all treatment, due to high costof watering

Effects of Harvesting Time and Types of Legume Cover Crop on SoilQuality in Dryland Farming. Dryland is characterized by limited water resources, itdepends on amount and distribution of rainfall and its low quality of soil. Effort onimprovement of soil quality have been reported could be done through incorporating biomassof legume cover crops (LCC). Time of harvesting (then incorporated) and types of LCCdetermine the nutrients in the biomass, which finally affects the soil quality. A fieldexperiment was conducted to study the effects of time of harvesting and types of LCC on soilquality in dryland farming area in the village of Sengguan, Gianyar Regency, Bali Provincefrom August to December 2015. The experiment was arranged in a completely randomizedblock design with three replications. The treatments were the times of harvesting (or thenincorporation) (3, 6 and 9 weeks after sowing or WAS) was assigned as the first factor whiletypes of LCC (Mucuna pruriens L. (kara), Crotalaria juncea L.(orok-orok), and Phaseoluslunatus L. (kacang arbila)) as the second factor. Results of experiment indicated thatincorporated LCC biomass significantly (P<0.05) increased soil quality (physically,chemically and biologically). Mucuna pruriens and Phaseolus lunatus harvested and thenincorporated at 3 WAS significantly (P<0.05) increased chemical (organic-C, total-N,available K) quality of the soil, while when harvested 9 WAS the effects were moresignificant on physical (bulk density and porosity) quality. Soil moisture content increasedwhen Phaseolus lunatus was harvested and incorporated at 3 WAS, while microbial activities(indicated by soil respiration) increased when Mucuna pruriens was treated at the same time.

The decrease of maize yields on dryland farming areas could have resulted from the effects of strong competition between plants in a population due to an inappropriate number of plants, corn variety, and limited growth factors. The use of the right number of plants hole-1 and variety is expected to increase corn seed yield. The results showed that in the population 285,714 plants ha-1, the yield of seeds weighing 7.78 g cob-1 at 12% moisture content and 7.73 ton ha-1 at oven-dry weight, produced by local varieties of the hill. This result indicates that the two factor of treatment did not have an effect on maize yield. The population treatment of 285,714 plants ha-1 yielding seeds weighing 135.23 g plant-1 dry weight oven and 7.73 ton ha-1 on oven dry weight. The local varieties of Bukit produced seeds weighing 90.20 g plant-1 at 12% and 5.13 t ha-1 moisture content on oven dry weight, potentially developed in dryland especially in Mumbul Park area, South Kuta in a population of 285,714 plant ha-1 (4 plants per hole).
