Abstract

Development of cattle in the Papua region still faces many obstacles, particularly the limited number of cattle population and the quality of the animal dominated by bali cattle. This study aimed to evaluate the productivity of bali cattle and their crosses with limousin and simental through artificial insemination. This study was carried out on December 2016 to February 2017  in the Arso and Skanto Districts, Keerom Regency, Papua. Ninty four heads of used in this study, comprising 57 bali catsle, 18 bali x limousin and 19  bali x simmental crosses through artificial insemination programe. Parameters vanahle included reproduction characteristics, body weight and linear body measurement.  The observation were conducted of calf (<12 month), young (13-24 month) and adult animal(>25 month).  The results indicated that the female bali cattle and their crosses with limousin and simmental raised on forage based feed showed different reproduction and production perfomances.  The cross bred cow (bali x limousin and bali x simmental) tended to have longer age at first mating, higher service per conception and lower calving rate.  Based on forage feed, the cross bred cow had significantly (P<0.05) higher body weight and body frame size, particularly body weght, hip height, body lengt and heart girh at adult age.  In general, the crosses between bali and limousin or simmental for cow-calf production could be developed on a forage based feed at Keerom District, Papua.

Abstract

Lettuce (Lactuca sativa L.) is a horticultural plant with high nutritional and economic value and good development prospects in Indonesia. However, the high costs of hydroponic fertilizers drive research to find more economical alternatives, such as substitution with Liquid Organic Fertilizer (LOF). This study aims to analyze consumer perceptions of hydroponic lettuce using LOF substitution and understand consumer responses and purchasing behavior toward these products to identify the attributes influencing purchasing decisions for hydroponic lettuce with LOF substitution. The study employs a survey method with purposive sampling, involving 35 regular customers and 15 supermarket shoppers from PT ABA to collect primary data through questionnaires regarding consumer interest in hydroponic lettuce with LOF substitution. Additionally, proximate analysis and nutrient content testing are conducted in the laboratory. Data analysis uses conjoint and discriminant analysis with SPSS Statistics 24 to evaluate consumer responses and the most preferred product model based on nutritional attributes, price, and weight. The study successfully analyzes consumer perceptions of hydroponic lettuce with LOF substitution and finds that consumers have a positive view of this product, mainly due to its better nutritional content and the plant's ability to absorb nutrients optimally. These factors significantly influence purchasing decisions, with the main attributes being price, weight, and nutritional content.

Abstract

This study aimed to evaluate the physiological response of female beef cattle to peatland microclimate stress in Central Kalimantan. This study used direct observation on small holder beef cattle farm. Microclimate data on 41 units cattle barns and physiological parameters of female cattle were collected in the morning, at noon and in the afternoon. The physiological parameter measurements involved 215 female beef cattle, consisting of 119 Bali and 96 crossbred cattle with different physiological stages including pregnant cows, lactating cows, dry cows, heifers and calves. The microclimate condition within cattle barns on peatland of Central Kalimantan is not the comfort zone for beef cattle. It is characterized by high air temperature and relative humidity, and low wind speed, which result in high temperature humidity index (THI). The barn with gable roof type and asbestos materials gave the lowest THI. This Microclimate caused heat stress to beef cattle reared on the peatlands, indicated by the high rectal temperature, heart rate, respiratory rate, and heat tolerance coefficient, although it was still categorized as mild to moderate stress. Bali cattle showed better physiological responses to microclimate stress than crossbred cattle. Pregnant crossbred cows were the most susceptible to peatland microclimate stress.

Abstract

Indonesia faces the challenge of declining agroecosystem quality due to the long-term use of synthetic chemical fertilizers, indicating the need for a transition to organic fertilizers to support sustainable agricultural practices. Therefore, this study aims to analyze the quality of liquid organic fertilizer made from dairy cow manure, laying hen manure, and Indigofera zollingeriana and to examine the effects of the combination of liquid organic fertilizer on the growth and yield of lettuce (Lactuca sativa L.). This research uses a Completely Randomized Design (CRD) experimental method with five treatments of liquid organic fertilizer (LOF) substitution and three replications to evaluate its effects on the growth and yield of hydroponic lettuce, where the data are analyzed using ANOVA and Tukey's post hoc test. The results show that the liquid organic fertilizer produced from the combination of dairy cow manure, laying hen manure, and Indigofera zollingeriana meets the quality standards of Minister of Agriculture Regulation No. 261 of 2019 with a total N content of 3.11%, P2O5 2.12%, and K2O 1.94%, and is effective in enhancing lettuce growth. The combination of liquid organic fertilizer and AB Mix, particularly AB Mix 75% + LOF 25% and AB Mix 50% + LOF 50%, results in optimal lettuce growth. Therefore, using a combination of liquid organic fertilizer and AB Mix can increase the efficiency of lettuce production in hydroponic systems and can be adopted by farmers to improve crop yields and quality.

Abstract

This study examined the effect of adding mealworm (Tenebrio molitor) frass to cow manure media on the productivity of Lumbricus rubellus and the quality of the vermicompost. A completely randomized design was employed with six treatments (T0–T5), consisting of increasing proportions of frass: T0 (100% cow manure), T1 (95:5), T2 (90:10), T3 (85:15), T4 (80:20), and T5 (75:25). The T2 treatment yielded the highest earthworm biomass gain (4.95 g), cocoon production (87.94 cocoons), and media reduction (198.83 g), all statistically significant (p<0.05). Vermicompost from each treatment was assessed through a growth trial using Ipomoea reptans (water spinach) under eight media combinations (U0–U7): U0 (100% soil), U1 (soil + NPK), and U2–U7 (soil + vermicompost from T0–T5, respectively). Among these, U7 (incorporating vermicompost from T5) demonstrated the highest nutrient content (C-organic 41.51%, N 1.99%, P₂O₅ 1.99%, K₂O 1.47%) and significantly enhanced plant growth (p < 0.05). These findings indicate that moderate frass supplementation (10%) optimizes earthworm productivity, while higher inclusion levels (25%) improve vermicompost agronomic value. Thus, moderate frass addition is recommended to optimize vermicompost production and worm performance.
