Coconut milk is a food ingredient that is used to increase the taste of food and drinks. Coconut milk has processed products in the form of traditional drinks such as ice dawet and cendol ice. According to the Indonesian National Standard in 2009 about Maximum Microbial Contamination in Food in liquid coconut milk must be in accordance with the requirements of TPC parameters, MPN Coliform, Salmonella sp., and Staphylococcus aureus. This study aims to determine the description of Staphylococcus aureus contamination in traditional coconut milk in the Banjarbaru region. This type of research is a descriptive survey. The samples in this study were traditional drinks (es dawet and es cendol) that used coconut milk by using Purposive sampling techniques as many as 6 sellers who made 2 times taking, namely taking 1 hour (testing I) after processing and 2 hours after the first take (testing II) . From the research that has been done, it is found that there are 4 samples of Staphylococcus aureus contamination in 4 samples, namely 3 samples fulfilling the requirements of the Indonesian National Standard and 1 sample that does not meet the requirements of the Indonesian National Standard. It is expected for the seller to always maintain personal hygiene, pay attention to the cleanliness of drinks sold either during processing or serving, noting the cleanliness of the appliance and storing the ingredients of the drinks sold.

Armyworms (Spodoptera litura) become important pests in Indoensia that eat leaves compared to other pests because they are polyfag. S. litura can reduce productivity even crop failure. Therefore, it is necessary to do research on how to control S. litura effectively and environmentally friendly. This study aims to determine the effectiveness of brotowali extract (Tinospra crispa) as a botanical insecticide and obtain the right concentration of fruit extract, young leaves, and old Brotowali leaves to control the armyworm (litura Spodopter). This study used a Non Factorial Completely Randomized Design (RAL) with 6 treatments of various doses of brotowali extract mixed with cow urine and 4 replications. The results of the study showed that the administration of Brotowali + Urine Cattle extract with high doses (30 ml / jar) was able to increase the speed of death of the armyworm. ABSTRAKUlat grayak (Spodoptera litura) menjadi hama penting di Indonesai, pemakan daun dibanding hama lainnya karena bersifat polyfag. S. litura dapat menurunkan produktivitas bahkan kegagalan panen. Oleh karena itu, perlu dilakukan penelitian mengenai cara mengendalikan S. litura secara efektif dan ramah lingkungan. Penelitian ini bertujuan untuk mengetahui efektivitas ekstrak brotowali (Tinospra crispa) sebagai insektisida botani dan mendapatkan konsentrasi ekstrak buah, daun muda, dan daun tua Brotowali yang tepat untuk mengendalikan ulat grayak (Spodopter litura). Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) Non Faktorial dengan 6 perlakuan berbagai dosis ekstrak brotowali yang dicampur urine sapi dan 4 ulangan . Hasil penelitian adalah menunjukkan bahwa pemberian ekstrak Brotowali + Urine Sapi dengan dosis tinggi (30 ml/toples) mampu meningkatkan kecepatan kematian ulat grayak.

Pakcoy (Brassica rapa L.) or commonly called mustard spoon includes vegetable plants that are heat resistant, so that they can be planted in the lowlands to highlands The production of packcoy plants experiencing ups and downs in 2010 is the peak production of 141.25 quality / ha and continues to decline to 2014 became 114.35 quality / ha. Efforts to increase packcoy production can be done by using organic fertilizers from agricultural waste, manure, green manure, human waste, and compost instead of nutrient sources. This study aims to determine the response of growth and production of Pakcoy plants to the provision of NASA POC organic fertilizer. This study uses factorial randomized block design consisting of 2 treatment factors, namely: Chicken Cage Organic Fertilizer (A) which consists of 3 levels, namely: A0 = 0 tons / ha, A1 = 15 tons / ha (158 g / polybag), A2 = 30 tons / ha (316 g / polybag). NASA POC concentration (N) consists of 4 levels, namely: N0 = 0% (control), N1 = 1 cc / liter of water, N2 = 2 cc / liter of water, N3 = 3 cc / liter of water. The results showed that NASA's POC showed a significant effect on pakcoy plant height, the use of liquid organic fertilizer dosage (2cc / ltr) had a significant effect on plant height. The highest pakcoy plant height is found in the treatment of N2 (2 cc / ltr) of 25.50 cm. The net weight per plot was obtained at the N2 treatment of 262.92 grams

Various fruit flies are in Indonesia, but only a few species of fruit flies have been found at the red guava plant in Deli Serdang District. Knowing the species of fruit flies are needed to do the proper control. In addition to morphological identification, it is necessary to carry out molecular characterization to obtain accurate results in characterizing species differences. This study aims to identify the fruit fly based on morphology and molecularly PCR-RAPD for mapping the genetic closeness of the relationship between individual fruit flies. Bactrocera morphologically identified at LIPI, namely <em>B. carambolae, B. papayae, B. caudata, B. albistrigata, B. umbrosa, B. curcubitae, B. tau,</em><em> </em>and<em> </em><em>B. kinabalu</em>. For molecular identification PCR-RAPD, shows the dendrogram results from the Neighbor-Joining analysis based on RAPD markers of DNA band characters showing the genetic proximity of eight species divided into three groups of Bactrocera based on their location. The closeness of genetic relationships between individuals was analyzed using Pairwise Distance Calculation which describes the genetic distance between species. The results of Pairwise Distance Calculation ranged from 0.13-0.42. By knowing what species there fruit flies are in red guava plantations in the Deli Serdang district, it can make it easier for farmers to monitor and control fruit flies in red guava plantations.

Pemupukan berpengaruh positif terhadap pertumbuhan dan produksi tanaman kedelai. Pupuk kompos merupakan pupuk organik yang diberikan kedalam tanah dapat meningkatkan unsur hara baik makro maupun mikro. Selain pemberian pupuk kompos dapat juga ditambahkan pemberian pupuk urea (sebagai pupuk anorganik) yang dapat memberikan unsur hara N bagi tanaman. Penelitian ini bertujuan untuk mengetahui pengaruh penggunaan dosis pupuk (kompos dan pupuk urea) dengan varietas terhadap pertumbuhan tanaman kedelai, serta menentukan varietas unggul yang terbaik terhadap pertumbuhan kedelai. Penelitian ini menggunakan rancangan acak kelompok (RAK) faktorial, dengan factor 1 dosis pupuk, D0: kontrol, D1:kompos 5ton/ha, D2 :kompos 10 ton/ha, D3: urea 25 kg/ha, dan D4 : urea 50 Kg/ha. Faktor 2 yaitu varietas dengan V1 : Varietas Anjasmoro dan V2 : varietas grobogan. Hasil penelitian menunjukkan bahwa pemberian pupuk kompos dan pupuk urea dapat meningkatkan pertumbuhan tanaman kedelai, dan juga mempercepat umur berbunga tanaman kedelai. Varietas grobogan memiliki umur berbunga paling cepat yaitu 32.33 hari dibandingkan dengan varietas anjasmoro. Peran pupuk kompos dan urea dalam penelitian meningkatkan unsur N tersedia bagi tanaman
