Anjing domestik (Canis lupus familiaris) dari famili Canidae merupakan salah satu spesies anjing yang telah melalui proses domestikasi. Masing-masing pemilik anjing akan memperlakukan hewan peliharaannya secara berbeda yang mengakibatkan perbedaan perilaku. Di antara lokasi-lokasi di kampus IPB Dramaga, lingkungan penangkaran Pusat Studi Satwa Primata menjadi salah satu tempat di mana anjing peliharaan banyak dijumpai. Metode focal animal sampling untuk mengamati perilaku anjing dengan interval waktu 10 menit dan data perilaku harian dibagi dalam 7 kategori yaitu ekskresi, lokomosi, perawatan diri, sosial, vokalisasi, inaktif dan negatif. Pada periode pengamatan dari pukul 09.00 hingga 13.00, tiga individu anjing menunjukkan perilaku istirahat dalam rentang 51-69% dan memilih lokasi yang dekat dengan pemilik untuk beraktivitas.

Potensi Waste Organic Product (WOP) FST 1310 terhadap Pertumbuhan Candida albicans Penyebab Kandidiasis

Candida albicans is an agent that causes candidiasis which can cause health problems in human’s organs. This study aims to determine the antifungal activity and inhibition zone diameter of Waste Organic Product (WOP) FST 1310 against Candida albicans. This type of research is experimental, using the Kirby-Bauer agar diffusion method with 6 treatments: P1: 100%, P2: 80%, P3: 60%, and P4: 40%, along with 2 controls, P5: nystatin (positive control) and P6: distilled water (negative control). The results showed that the WOP FST 1310 from orange peel had a larger inhibition zone diameter compared to the vegetable-derived. For the vegetable-derived eco-enzyme, the highest inhibition zone diameter was at a 100% concentration with an average of 3.7 mm. Meanwhile, for the orange peel eco-enzyme, the highest inhibition zone diameter was at a 40% concentration with an average of 5.3 mm.

The type of coffee commonly grown by Indonesian farmers is robusta coffee (Coffea robusta). The processing of robusta coffee has so far focused on producing coffee beans with good flavor, leaving behind coffee pulp waste that needs to be utilized. This study aims to utilize coffee pulp waste to produce vinegar through a fermentation process using Saccharomyces cerevisiae and Acetobacter aceti. Vinegar production begins by rejuvenating A. aceti in YPG media and creating a growth curve. The fermentation of coffee pulp into vinegar involves two fermentation stages: alcoholic fermentation and acetic acid fermentation. Observation of the culture at the end of fermentation includes pH value, total acetic acid content, sugar content, and substrate utilization efficiency in product formation. The growth curve of A. aceti reaches the log phase at the 6^th to 8^th hour with a µmax of 0.45 hours^-1. Vinegar from coffee pulp has the highest total acetic acid in 10 days of alcoholic fermentation and 7 days of acetic acid fermentation, which is 2.37%, with a pH value of 3.02, a Yp/s value of 0.995, and a ∆S/S value of 0.69. The amount of acetic acid obtained does not fulfill the requirements of SNI 01-4371-1996.

Fusarium oxysporum is one of the primary pathogens in tomato plants that causes plant wilting. Pathogenic fungi have been controlled by spraying synthetic fungicides. The negative impact of excessive use of synthetic chemicals can be reduced by using biocontrol agents that produce antifungal compounds. Natural pest control efforts use endophytic bacteria and rhizosphere as biocontrol agents for fungal pathogens on tomato plants (Solanum lycopersicum L). This study aims to select and test biocontrol bacteria against pathogenic fungi Fusarium sp. isolated from tomato fruits. Fusarium successfully isolated from tomato fruits which was characterized based on observations of colony and cell morphology. A total of 15 rhizosphere bacterial isolates were tested against Fusarium sp., and 11 bacterial isolates were able to inhibit the growth of the fungus. Isolates TTSG 2.2, TTSG 2.7, TTSG 3.2, TTSG 3.5, TTSG 3.6, and TCS 3.1 had fungal inhibition of 45%. The results of the hemolysin test showed that one isolate, TTSG 3.6 isolate, was negative, which did not form a clear zone around the bacterial streak. Isolate TTSG 3.6 still showed a few brown spots and rotted tomato fruit, so this bacteria needs to be tested for hypersensitivity on tobacco leaves to show its pathogenicity in plants.

The use of medicinal plants to treat disease is still used in many areas. This research aimed to provide information about medicinal plants in Sumber Sehat Multifarm. Data such as local name, scientific name, habitus, part of the plants that are used, benefits, how to use, and also plant processing were collected through a semi-structured interview method. Data analysis was done through a quantitative method which calculated calculating the percentage of parts of the plants that were used and the habitus of the plants that were found. Qualitative analysis of data was done descriptively. The result showed that Sumber Sehat Multifarm uses 177 species belonging to 64 families as medicinal plants. Most plant species have herbaceous habitus. Part of the plants that are used mostly are the leaves. Most plant species of plant can treat more than one kind of disease. The benefits of the plant can be grouped into two categories: plants used to cure internal organ disease and plants used to treat external organ disease. Most plant species can be consumed by brewing or freshly eaten.
