Abstract
Silvoaquaculture is one of environmentally friendly aquaculture, which is integration between fish ponds (brackish water aquaculture) and mangrove tree in the coastal area. In Indramayu Regency, silvo-aquacultures are located in Karangsong, Brondong and Tegur village. Milk fish (Chanos chanos) was cultured at silvo-aquaculture in Indramayu Regency. The objective of this study is to know water quality at silvo-aquaculture ponds in Indramayu Regency. The water quality has been measured includes temperature, salinity, pH, brightness, DO, nitrate, phosphate, and ammonia. The ranges of water quality values at silvo-aquaculture ponds in Indramayu Regency are Brondong Village {temperature (29.8-33.0 °C), salinity (26-30 ppt), pH (7.27-7.80), brightness (26.5-91 cm), DO (3.1-10.7 mgL−1), nitrates (12.5 mgL−1), phosphates (0.03 mgL−1), and ammonia (0.25 mgL−1)}; Karangsong Village {temperature (29.5-31.0 °C), salinity (17-25 ppt), pH (7.29-7.51), brightness (39.5-47 cm), DO (2.2-4.4 mgL−1), nitrates (12.5 mgL−1), phosphates (0.03 mgL−1), and ammonia (0.25 mgL−1)}; and Tegur Village {temperature (30.4-31.8 °C), salinity (15-19 ppt), pH (7.14-8.18), brightness (32.25-48.25 cm), DO (8.8-9.5 mgL−1), nitrates (12.5 mgL−1), phosphates (0.03 mgL−1), and ammonia (0.25 mgL−1)}. Analysis of variance showed temperature, pH, brightness, phosphate, nitrate, and ammonia were not significantly different between locations, but salinity and DO were significantly different between locations. These results indicate all water-quality parameters are suitable for fish culture. The lower salinity presented in Tegur Village was affected by rainy. Interestingly, DO concentrations in the Karangsong silvo-aquaculture pond are lower than optimal value (<5.00 mg/l), but they are still suitable for milkfish life (> 2 mg/l).

Published: December 2019

Abstract
Indonesian are very dependent on wheat flour, even though wheat are subtropical plant. Therefore, the Indonesian government must import wheat continuously to supply the demand. While there are many potential local carbohydrates sources that have not been utilized such as tubers. One of local carbohydrates source is Talas beneng which only grows in Pandeglang Regency, Banten. This tuber grows wildly and is underutilized because it contains oxalate which causes itching when consumed. Oxalate reducing is done by soaking the taro in 1% NaCl for 60 minutes. To easier application on food products, this tuber can be made as starch. The aim of this study were to choose the best extraction method in producing starch and determine the color and chemical characteristics. The extraction method used was carried out with five attempts and two repetitions, with a ratio of taro and water 1:1, 1:2, 1:3.1:4, and 1:5. The results showed that the ratio that produces the biggest yield is 1:3 with the result 12.67%. Chemical characteristics of talas beneng starch are produce an L value 100, 00, a* 10.92, b* -15.54, and contains moisture 6.21%, ash 0.25%, fat 10.56%, protein 0.66%, starch 82.32%, amylose 28.91%, amylopectin 53.41%, and oxalate reduction 97.4%.

Abstract
Paper mulberry (Broussonetia papyrifera L.) is a type of emerging feed and very popular with its high nutrition and low-cost value. Purpose of the experiment was to evaluate the nutrient contents, amino acids content and in vitro ruminal dry matter digestibility of paper mulberry cut at four different heights (60, 90, 120, and 150 cm). Paper mulberry harvested at 60 and 90 cm increased the content of crude protein water-soluble carbohydrate, calcium and total amino acids (P<0.05). There were 10 of 16 kinds of amino acids at relatively high content at 120 cm (P<0.05) while phosphorus content was the highest (P<0.05). The harvesting height of 150 cm showed higher content of neutral detergent fiber and acid detergent fiber than the other treatments (P<0.05). No significant difference appeared in the content of hydrolysable tannins (P>0.05), but the lowest content of condensed tannin was measured at 150 cm (P<0.05). In terms of in vitro ruminal dry matter digestibility, the sample cut at 150 cm was the lowest in all samples (P<0.05). In summary, the recommended choice of harvesting at 90 cm gave the best quality paper mulberry raw material.

Authors: Prasojo Y S , Ishigaki G , Fukuyama K , Akashi R 
Published: December 2019

Abstract
Tropical grasses mainly utilized in southwestern Japan exhibited that the dry matter yield is increased as the growth stage. However, the nutritive value, such as crude protein (CP) and non-fibrous carbohydrate (NFC) decreased strikingly. Therefore, breeding for the new grass or crops with high potential as protein source is an urgent problem. The aim of the study were to investigate the dry matter yield of two soybean cultivars (‘Miyakonojo’ and ‘Williams82’) with Rhodes grass as living mulch plant after 1st cutting and to investigate the nutritive value of the silage. The growth of the Rhodes grass hampered the growth of soybean at the initial and the subsequent growth stages. Hence, the dry matter yield of soybean ranged from 9.8 kg/10a to 26.6 kg/10a, correspond to about 3 to 10% of total dry matter yield. The nutritive value of EE, CA and CP in Rhodes grass with soybean silage higher than those of Rhodes grass silage. These results suggest that the addition of soybean biomass could be useful for increasing the nutrition value of silage. Moreover, it is necessary to choose an appropriate sowing date to increase dry matter yield of soybean biomass in southwestern of Japan.

Abstract
The purpose of the study was to evaluate the quality of fermented goat milk using Lactobacillus plantarum and determine its antibacterial ability against enterobactericeae. The quality of fermented milk was evaluated through measurement of pH, lactic acid levels, protein content and total bacteria. The antibacterial ability was measured by inhibitory tests on enterobactericeae. The experiment was applied in a completely randomized factorial design with two factors, namely factor A, type of milk (goat’s milk and powder milk), factor B, level of Lactobacillus plantarum (2.5, 5 and 7.5%) and 3 equal replicates. The data were subjected to analysis of variance, and continued to Duncan’s multiple range test to determine the difference between means at 1 % probability. The results indicated that milk type and L. plantarum levels had a very significant effect on pH, lactic acid levels, and the inhibitory zone width. There is an interaction between factors. Meanwhile the type of milk had very significant effects (P <0.01) on protein content and total lactic acid bacteria. In conclusion, fermented goat milk has better quality and antimicrobial ability against enterobactericeae than powder milk.

Abstract
Local cattle production in South Kalimantan (KalSel) has been unable to meet the demand, thus live cattle were imported from other islands.. Cattle imports have increased in recent years, thus local smallholders are experiencing falling prices. The objectives of this paper are to understand the market chains of cattle trading from interislands, and to assess the cost competitiveness of local cattle to the imports. Methods used in this research are market chain and gross margin analysis. Key findings are: KalSel imported approximately 5000 head live cattle per month, mainly from NTT and NTB, followed by South Sulawesi and East Java; cattle from East Java were Limousin and other crossbreeds, other provinces supplied mainly Bali cattle; interisland cattle were traded based on price per kg and actual live weight, while local cattle were based on price per head and estimation of live weight; cattle from East Java was most price competitive, followed by NTT/NTB and then South Sulawesi; in terms of taste, beef from crossbreeds was better, followed by beef from Sulawesi, and then from NTT or NTB; and finally local cattle were cost uncompetitive because of the pricing method used, small scale production and low productivity.

Abstract
The objective of this study was to observe the production traits of black and brown Japanese quails. The materials used were female black and brown Japanese quails originated from two distinct breeding farms. One hundred Japanese quails were divided into four types of line as treatments: Black1 (L1), Brown1 (B1), Black2 (L2), and Brown2 (B2). Each treatment consisted of 25 quails as replication. The experiment used commercial feed for both starter and layer periods. This study used a Completely Randomized Design (CRD). The observed variables were body weight at 42 days, age at first egg, egg weight, and egg production. The data was analyzed with ANOVA, and differences among treatments was inspected using Duncan’s multiple range test (DMRT). Body weight and egg weight were significantly different among lines. Body weight in L2 and B1 populations were higher than L1 and B2 lines (P<0.05). In addition, higher egg weight was also found in L2 and B1 lines (P<0.05). Age at first egg-laying and egg production were not different among lines. These findings confirmed the presence of high variation among quails. A breeding strategy need to be developed to obtain quails with less diverse genetic background; thus, increase the farms’ management efficiency.

Abstract
Bligon is a crossbred goat that is widely raised in rural areas of Indonesia where goat farming is characterized by low productivity due to the low quality and availability of feed. The aim this study was to test the effect of sex on nutritional status of post-weaned Bligon goats under controlled feeding management. In total 16 post-weaned goats (age 4 months), were fed with the same diets that meet the basic requirements for goat maintenance. They were targeted to reach average daily gain (ADG) of 100 g. The diet contained 14.58% crude protein and 80.78% total digestible nutrient. All goats received 3% to 4% dry matter ratio of the body weight. Water was provided ad libitum. The variables observed were nutrient intake and digestibility, ADG, and feed conversion ratio (FCR). It was found that sex had a significant effect (p<0.05) on crude fiber (CF) intake, ADG and FCR, with mean values of 10.13±1.23 g/kg BW0.75/day, 80.62±25.11 g, and 5.88±1.69 in female goats, respectively, and 11.06±1.64 g/kg BW0.75/day, 132.25±27.71 g, and 3.61±0.62 in male goats, respectively. In can be concluded that sex affects CF intake, ADG and FCR of post-weaned Bligon goats.

Abstract
Mixed farming system is an alternative to overcome the shortage of ruminants feed. This study aimed to observe the potential forage production in mixed cropping pattern on dry land agriculture. This research was conducted at the Agro Technology Innovation Center (PIAT) Universitas Gadjah Mada, from January until November. The research field size was 3.000 m2 divided into 2 blocks for monoculture and mix-cropping. During rainy season the sweet corn was planted on monoculture plot; on mix-cropping plot 1.000 m2 was planted with sweet corn and the rest was planted with Brachiaria brizantha, Arachis hypogaea, and Manihot utilissima. Gliricidia maculata is planted as a hedge that surrounds the mixed plot. After the first harvest, both plots were re-processed and planted with Arachis hypogaea. Forage sampling was done using the quarter method. The variables observed were the production of dry and organic matter of agricultural by-product, in vitro digestibility of dry and organic matter, and the economic income of the main crops. The data were analyzed using Independent sample t-test. The results showed an increase (P<0.05) of production, digestibility, and economic income with the existence of mixed cropping. Mixed cropping provides better production, digestibility and economic income compared to a single planting.
