Abstract

This research aims to find out what % of coli fruit fiber juice is used to produce good quality silage, and to find out the physical quality of field grass silage with the addition of coli fruit fiber juice. The materials used in this research were field grass and coli fruit fiber juice brought from Moa Island, Southwest Maluku Regency. This research will be carried out for 2 months (October-November, 2022) at the Faculty of Agriculture, Animal Husbandry Department, Pattimura University, Ambon. The harvested silage will be subject to observation and/or physical analysis of field grass silage at the Animal Nutrition and Forage Laboratory, Pattimura University, Ambon. The variables observed were color, aroma, texture, pH and the presence or absence of mold in the silage. The physical quality was tested by the 5 students selected as panelists using the questionnaire provided.

Abstract

This research aims to determine the potential for forage for ruminant livestock under coconut trees in Huamual District, West Seram Regency. Three villages, namely Ariate Village, Loki Village and Luhu Village, were selected using the pruple sampling method. This research uses a survey method through direct observation and measurements in coconut plantation areas. This research was carried out using the dry weingh rank method to measure botanical composition, to calculate forage production using the Actual Weight Estimate method and measuring carrying capacity using the Voisin (y-1) s = r formula. The results of this research show that the botanical composition of the forage found in the area under coconut trees is 14 species consisting of 7 species of grass, namely paspalum (Paspalum distichum), charred grass (Sporobolus indicus), Bermuda grass (Cynodan dactylon), Bengal grass (Panicum maximum), carpet grass (Axonopus compresus), buffalo grass (Paspalum conjigatum), field puzzle grass (Cyperus rotundus) 63.49%, 5 weed species namely Chinese purslane (Euphorbia prostrate), lizard fern (Cyclosorous aridus), minjang (Chormolaena odorata ), flower fern (Lygodium flexuosum), galunggang (Sida acuta) 28.10% and 2 species of butterfly pea legume (centrosema), calopo (calopogonium) 9.13%. This shows that the most dominant grass is paspalum grass (paspalum distichum), forage production has a fresh weight of 3847.86 tons/year and the carrying capacity in the area under coconut trees is 0.441 Ha/UT or 2.27 UT/Ha. With a total area of 1211 coconut trees, it can be estimated that it can accommodate 534,051 and the data on the ruminant livestock population in Huamual sub-district is 710,949 UT/year.

Abstract

This study aims to determine the productivity of Lakor goats in rural conditions on Lakor Island, Southwest Maluku Regency. This researchwas conducted in October-November 2022 on Lakor Island. This research used This study used 60 Lakor goat breeders as respondents and the design. The results of this study showed that the average birth weight was 1kg, weaning weight was 13,15kg, bodyweight for kid goats aged 1-2 years was 86,91-22,84kg, number of matings 1,5-3 times, type of birth from a single sample village 11,32, twins 42,14, triplets 19,93, litter size 1,97, pre-weaning motility 7,33, sex ratio 3,31-3,70 and estrus cycle 18-24 days. It can be concluded that the productivity of Lakor goats in rural conditions in Pulau Lakor, West Maluku districtthe power is very good because even though the rearing of goats on Lakor Island is semi- intensive, green feed on Lakor Island really meets the needs of livestock so as to produce ideal body weight.

Abstract

The seagrass species Enhalus acoroides is able to live widely, especially on smooth, muddy substrates, but is also able to grow on rocky substrates. It is often found growed together with other types of seagrass, thus forming monospecific vegetation in various habitats. The aim of this research is to determine the amount of vitamin C content made from seagrass leaves. The object in this research was Enhalus acoroides seagrass leaf tea taken from the beach of Suli Village using purposive sampling of 1.5 kg. Seagrass tea is made in the Basic Chemistry Laboratory, Pattimura University. Vitamin C analysis was carried out at the Biochemistry Laboratory, Pattimura University. Vitamin C levels in seagrass leaf tea vary for each repetition or observation sample. In sample code C1, the sample weight (g) is 10.0520, ml Titran(I2) 8.2, Vitamin C (Mg) 7.216 and vitamin C content is 0.071%, for sample code C2 the sample weight (g) is 10, 0740, ml Titran(I2) 10.3, Vitamin C (Mg) 9.064, vitamin C content of 0.090%. Meanwhile, the average amount of vitamin C is 8.14 Mg and has a vitamin C content of 0.08%. The average value of vitamin C is 8.14 Mg, while the amount of vitamin C in seagrass leaves is 0.08%. So it is very possible that Enhalus acoroides seagrass can be used as a new food preparation that is rich in nutritional content.

Abstract

Hotong (Setaria italica (L.) P. Beauv) is a type of food plant that is used by the people of Buru Island, Maluku. The hotong is a plant whose contents are similar to the rice plant. Hotong seeds have quite high nutritional content, namely containing 11.18% protein, 2.36% fat, 73.36% carbohydrates, 11.78% water, and 1.32% ash. The energy produced per 100 grams of hotong seeds is 359 calories. Hotong plants can be used as an alternative commodity in a carbohydrate-produced food diversification program. Various local carbohydrate source commodities can be produced into flour to substitute wheat needs, save the country's foreign exchange and increase food security. Based on the availability of raw materials and prices, hotong has the most potential to be processed into flour. Hotong research results are the most numerous among carbohydrate source commodities. Until now, the name has not been able to be utilized by the public, compared to rice and wheat. This is one consideration that hotong flour can improve the image and interest of users. Hotong flour, with various technological variants, can be used for various flour-based food products, but nationally the real impact on reducing wheat consumption is still not significant. Therefore, it is necessary to discuss the prospects and potential for its use in the food industry.

Abstract

The inquiry approach is one of the approaches proposed by experts to be developed in the learning process. Where inquiry learning teaches students how to research problems or questions of facts. Learning used an inquiry approach requires a classroom environment where students feel free to create, make assumptions and draw conclusions. The aim of this research is to determine the improvement in biological science learning outcomes regarding the concept of photosynthesis used a contextual-based inquiry learning approach for class VIII3 students at Junior Hight School Negeri 2 Ambon. This type of research includes descriptive research using a PTK design. This research was conducted at a Junior High School Negeri 2 Ambon. The subjects in this research were students in class VIII3 as many as 26 students. Data analysis uses qualitative data, then the final value is converted using completeness criteria. Based on the tests gived in cycle I, the final test results for each group were not significant. In group I, only 4 students (15.4%) had not reached the completion criteria and 5 other students were able to achieve completion with a percentage (19.2%). The number of students who achieved completeness in group II was 7 students (27.0%), and 2 other students (7.7%) did not achieve completeness. Meanwhile in group III, there were 5 students who were able to achieve completeness with a percentage of (19.2%) and 3 students (11.5%) who did not achieve completeness. Thus, there were 9 students (34.6%) who had not achieved completeness and 17 students (65.4%) had achieved completeness. Meanwhile, in cycle II the test results increased. In group I, there were 5 students who met the completion criteria with a percentage of 19.2%, 4 other students still had not completed it. Group II increased even more, 7 students (27%) met the criteria for completion while 2 students (7.7%) still did not complete. In group III there were 5 students (19.2%) who met the criteria for completion, and 3 other students (11.5%) who still had not completed it. The final test seems to show very good results. The conclusion of the research was taught used a contextual-based inquiry approach to the concept of photosynthesis can improve student learning outcomes, seen in cycle I and cycle II because the cognitive, affective and psychomotor aspects can improved.
