Abstract

Coral reefs are one of the most ecologically productive and diverse ecosystems. This study aims to determine the condition of scleractinian coral cover in the northern coastal waters of Ambon Island. Data collection in the field is carried out using the systematic sampling method. A quadrant measuring 1x1 m2 becomes the sampling area. Quadrants are placed on transects 20 m long with quadrant intervals on transect lines of 5 m (0, 5, 10, 15, and 20 m). The transects are placed parallel to the shoreline at depths of 3 m and 10 m, with four transects at each depth, and the distance between transects is 1 m. The data obtained were then analyzed to see the percentage of coral cover in each category and component. The results showed that the percentage of the benthic substrate of coral reefs on the North Coast of Ambon Island to a depth of 3 meters was dominated by rubble with a percentage of 26.33% - 54.83%, and for a depth of 10 meters the percentage value of ruble was 11.33% - 48.83% and sand (4% - 54.50%). The category of Acropora corals both at a depth of 3 meters and 10 meters dominated by Acropora branching (ACB), while the non-acropora category is dominated by Coral Branching (CB), Coral Encrusting (CE), and Coral Massive (CM). Overall, the condition of live coral cover on the North Coast of Ambon Island is categorized as in poor condition.

Abstract

Plantations represent a vital economic sector in Indonesia. However, farmers who rely on plantations for their livelihood often encounter challenges related to air and soil quality, which can significantly impact plant growth. Each type of plant requires specific air and soil conditions to thrive optimally, including factors such as air temperature, humidity, soil moisture, and pH levels. To address these issues, a solution has been developed in the form of a plantation monitoring system that can be accessed remotely and in real-time through cellular and desktop applications. This monitoring system utilizes various sensors, including DHT11 sensors, resistive soil moisture sensors, and soil pH sensors, all of which are meticulously calibrated with digital soil sensors. The collected data can be conveniently monitored and managed through an Internet of Things platform, such as Blynk.Based on the case study, the measurement system that is displayed on Blynk has a range of 0-100 °C for air temperature, 0-100% for air humidity, 0-1000 for soil moisture, and 0-14 for soil pH.

Abstract

Evaluation of nutrient availability needs to be carried out to determine the ability of the soil to provide nutrients for plant growth, in this case the evaluation of the nutrient content of paddy fields in three locations in the Balige area, namely Huta Namora, Huta Bulu Mejan and Baruara. This is needed as information for the management of paddy fields on the provision of fertilizers in the future, both inorganic fertilizers and organic fertilizers. The purpose of this study was to evaluate the availability of soil nutrients such as organic C, total P, available P and soil pH after rice harvest. This research is a descriptive study by comparing data from the three research locations. In its implementation, 9 sample points of observation were chosen representing the location of each area. Every 3 sample points were mixed into one point of soil samples from the three research locations showing relatively the same results so that in one location there were 3 points of soil samples which were considered as replication 1, 2 and 3 replications. Thus, there were 9 soil samples for the three research locations. Based on the results of laboratory analysis shows that the nutrient content is relatively the same, namely for organic C content with low to moderate criteria, P-total nutrient content is on average between 6.55-7.52 (%) (low to moderate), for P is available between 27,241 – 28,909 with very low criteria. The pH parameter for paddy fields is relatively the same as the neutral criterion. This information becomes quite expensive information for the management of paddy fields in the future. The suggestion is to reduce the use of inorganic fertilizers and switch to the use of biological fertilizers and organic fertilizers.

Abstract

Conservation is one of the efforts that can be made to prevent the decline in the population of Mentilin (Chephalophacus bancanus bancanus) and maintain its existence in nature so that the population is not disturbed. PPS Alobi is an animal rehabilitation center that plays a role in ex-situ conservation efforts for wild animals, so it must have the capacity to realize the ideals of conserving wild animals while ensuring the welfare of these animals in captivity. This research aims to determine the management of keeping mentilin (Cephalophacus bancanus bancanus) in captivity at the Alobi PPS as a means of ex-situ conservation of wild animals. The research was conducted using a survey approach, open and closed interviews, and questionnaires. Mentilin (Cephalopachus bancanus bancanus) maintenance management at PPS Alobi based on drum management parameters adopts an outdoor cage concept. It is built based on the natural needs of mentilin (Chephalophacus bancanus bancanus), and there is environmental enrichment for mentilin activities. Feed management operational standard feed management includes feeding based on the type and amount of feed as well as the frequency of feeding. Health management carries out animal health checks when the animals enter the Alobi PPS, followed by routine checks on the animals. Intensive care for animals that are sick or in unhealthy conditions means the frequency of administration of medicines and vitamins will be more intensive. Animal Health Management is to determine the animal's condition to be released back into its habitat and is supported based on knowledge of Mentilin primate animal conservation. Keywords: Mentilin (Cephalophacus bancanus bancanus), Exsitu conservasi mentilin, Maintenance management mentilin.
