Abstract
Predicting cattle’s body weight is a common practice considering various reasons. This paper revisits four classical formulas commonly found in papers published by Indonesian researchers in predicting cattle’s body weight based on their body measurements namely Schoorl, Winter, Smith and Lambourne models. Data on body weight (BW) and body measurements (Chest Girth=CG and Body Length=BL) of 118 male and 106 female Bali cattle (2-3 yo) were collected from Bali cattle Breeding Center. The estimates from the prediction formulas were compared to the actual body weight. We run 10-folds cross validation procedure to obtain the predictive ability parameters. The mean BW, CG and BL for male cattle were 199.19±51.51 Kg; 144.55±13.43 cm and 107.86±9.30 cm; whereas for females were 161.34±34.35 Kg; 134.25±10.26 cm and 101.48±3.60 cm respectively. All four formulas have the accuracy between 84.90 to maximum of 89.68% in both male and female cattle groups. RMSE were considerably high in both male group (17.64 – 45.31) and female group (11.52 – 26.61). Although the correlations between actual and predicted BW are high, further study need to be done to determine whether the utilization of these predicted values as a response variable will introduce enough bias to affect the results of a research.

Published: January 2021

Abstract
Applying the multivariate cointegration tests with daily prices during the period August 15, 2019, to August 11, 2020 (250 data), this paper examines whether prices in the rice deficit market (Jakarta) are co-integrated with prices in surplus markets (Semarang and Surabaya). Research data is the average daily price in traditional markets in Jakarta, Semarang, and Surabaya. The main focus is on the effect of implementing various programs and policies relating to controlling the spread of COVID-19 to the integration of the rice market in Java. On March 02, 2020, the first two COVID-19 cases in Indonesia were confirmed as a dummy variable that we use regarding controlling borders between regions and restricting the movement of goods. The cointegration tests find that the domestic rice prices of Jakarta - Semarang and Jakarta - Surabaya are integrated both in short-run and long-run periods. In the short term, programs and policies relating to controlling the spread of COVID-19 do not affect the integration of Java’s rice market. One reason is that during the pandemic, the rice supply chain’s performance was still protected by the government to maintain the stability of rice supply for the citizens.

Abstract
An alternative that can be used to reduce the impact of drought stress is the addition of micro-nutrients, one of which is Zn. Zn application on several plants has been done and showed an increase in the ability of plants to deal with drought stress. However, the application of Zn in drought tomatoes has not been well investigated. Therefore, the research aims to study the application of ZnSO4 on root and shoot growth of drought tomatoes. The study used two factors, namely cultivar (‘Tyrana F1’ and ‘Permata F1’) and ZnSO4 doses (0, 10, 20, 30 and 40 mg Zn kg-1 soil). The treatments were arranged in factorial based randomized complete block design. Drought conditions are applied by watering through once every eight days. The results showed a different response in a total root length in both cultivars within the ZnSO4 application. ZnSO4 application increased root dry weight; however, there is a no different response in the shoot growth of tomato under drought stress. Root dry weight increased 36.8-62.5% on application 20-40 mg kg-1 ZnSO4 under drought condition.

The experiment was undertaken in Setiling Village, Central Lombok (at ca. 650 m amsl) and arranged according to a RCBD two factors: variety (v) and dosages of NPK fertilization (n). The first factor were four carrot varieties: Gundaling (v1), Kirana (v2), New Nantes (v3) and New Kuroda (v4), while the second factor were four dosages of NPK fertilization: 50 kg/ha (r1), 100 kg/ha (r2), 200 kg/ha (r3) and 400 kg/ha (r4). The results showed that there was no interaction between carrot varieties and rate of NPK fertilization on influencing growth and yield of carrot in medium latitude. However, growth and yield of carrot in medium latitude were significantly influenced by variety and rate of NPK fertilization, as shown by differences in the ratio of above and below ground biomass, tap-root weight, tap-root diameter and the ratio between cortex and stele. Accordingly the suitable variety for cultivation in the medium latitude was Gundaling variety (v1), with a higher growth and yield were obtained by NPK fertilization at rate of 200 kg/ha (n3).

Abstract
This study examined the allocation of agricultural credits by farmer households and the effect of changes in agricultural credit policies and cattle-raising business input. The study was conducted in Kupang and East Central Timor (Timor Tengah Selatan (TTS) Regencies, East Nusa Tenggara (Nusa Tenggara Timur (NTT) Province, which is cattle production center and where the largest number of farmer households received agricultural credit in NTT. The data were analyzed using the 2-SLS method and the results were then validated and utilized using simulation models. In simulation 1, the agricultural credit increase was 25%, in simulation 2 the cattle-raising business input productivity increase was 20%, and simulation 3 was a combination between simulations 1 and 2. The study results revealed that in order to stimulate the increase in productivity and cattle-raising business production, it was not enough to provide agricultural credit, but it must be followed by improvements in the productivity of the cattle-raising business input such as improvements in the quality feeder calves, feed, and veterinary drugs. The policy implications are that agricultural credit is needed and it stimulates the use of better livestock-raising business input.
