Abstract

Abstrak: Kelapa sebagai tanaman yang diusahakan turun-temurun masyarakat di Kecamatan Kubu, Kabupaten Kuburaya, menghadapi masalah serangan hama. Sebagian besar pohon kelapa terserang parah hama kumbang badak (Oryctes rhinoceros Linn). Dampak serangan hama menyebabkan penurunan produktivitas kelapa sangat drastis. Kegiatan pengabdian masyarakat dilaksanakan dengan metode ceramah dan praktek. Materi ceramah bertujuan untuk memberi bekal kepada masyarakat tentang perlindungan tanaman kelapa terhadap hama kumbang badak. Metode praktek dilakukan dengan transfer teknologi berupa, perbanyakan isolat Metarhizium spp. pada media jagung dan larva kumbang serta pembuatan perangkap kumbang badak menggunakan tumpukan sisa sampah kebun kelapa dan trapping dengan feromon. Hasil kegiatan menunjukkan bahwa peserta menguasai perbanyakan Metharhizum spp. baik pada media jagung maupun larva. Peserta dapat membuat perangkap kumbang badak menggunakan sampah kebun. Pemasangan perangkap di 6 titik selama 10 minggu menunjukkan bahwa populasi kumbang badak di perkebunan kelapa tergolong tinggi. Secara keseluruhan penggunaan jamur Metarhizium dan feromon mampu mengurangi populasi kumbang badak. Pengendalian hama kumbang badak akan efektif apabila dilakukan oleh setiap petani kelapa dan dilaksanakan secara terus menerus sampai populasi hama dibawah ambang ekonomi. Abstract: As a plant cultivated from generation to generation in Kubu District, Kubu Raya Regency, coconut plants face pest attacks. Most of the coconut trees are badly affected by the rhinoceros beetle (Oryctes rhinoceros Linn). The impact of pest attacks caused a drastic decrease in coconut productivity. Community service activities are carried out using lecture and practical methods. The lecture material aims to provide provisions for the community about protecting coconut plants against rhino beetle pests. The practical method was carried out by transferring technology in the form of multiplication of isolates of Metharhizum spp. in the media of maize and beetle larvae and making rhino beetle traps using a pile of coconut garden waste and trapping with pheromones. The activity results showed that the participants mastered the propagation of Metharhizum spp both on maize and larval media. Participants can make rhino beetle traps using garden waste. Laying traps at 6 points for ten weeks shows that the rhino beetle population in coconut plantations is high. Overall, the use of Metarhizium mushrooms and pheromones was able to reduce the rhino beetle population. Rhino beetle control will be useful if done by every coconut farmer and carried out continuously until the pest population is below economic threshold

Abstract

Sago is a source of carbohydrates that has the potential to be used as a raw material for processed foods such as crackers. Crackers are a food that people like because they crunchy and can be used as a snack or complementary to the main daily menu. Improving the quality of sago crackers can be done by subtituting tapioca and seaweed pulp, which will provide more swelling power and higher protein levels. This research aims to determine the effect of subtituting tapioca and seaweed slurry on the physicochemical and organoleptic characteristics of sago crackers and determine the formulation that produces the best sago crackers. The design used was a Randomized Block Design (RBD) with one factor (p) ,consisting of 6 treatment levels and four replications. The results showed that subtituting tapioca and seaweed porridge affected the swelling power, water content, ash content, and protein content of sago crackers but did not affect the fat and carbohydrate content. The subtitution of tapioca and seaweed slurry produced the best physicochemical and organoleptic properties in the formulation of sago starch: tapioca: seaweed slurry (70:5:25) with swelling power of 76.78%, water content of 7.06%, ash content of 2.86%, fat content 12.88%, protein content 0.56%, carbohydrate content 77.72%, color 3.47 (like-very like), aroma 2.97 (dislike-like), taste 3.57 (like -like very much), crispness 3.73 (like-very like) and overall likeability 3.67 (like-very like).

Abstract

One aspect of cultural diversity is traditional food. Traditional food serves as a means of expressing thanks, performing cultural rituals, building kinship as well as being a source of nutrition. West Kalimantan is one of the multi-ethnic provinces in Indonesia, hence it offers a wide range of traditional foods. The existence of traditional food is threatened to be shifted or replaced by the presence of ready-to-eat food, which is intensively promoted in various media, with the main target being the young age group. This study aimed to determine student’s preferences in Pontianak towards traditional food in West Kalimantan and compare its nutritional composition with ready-to-eat food. This research was conducted using a survey to 150 respondents using online questionnaire. Data were analyzed by the Chi-Square program. The three types of traditional foods that respondents liked the most were tested for their nutritional composition and compared with the nutritional composition of ready-to-eat foods like chicken nugget, hamburger, and fried chicken. The results showed that students in Pontianak had a high preference (90.7%) for traditional West Kalimantan food. West Kalimantan's most preferred traditional foods were kerupuk basah (n=51), bubur pedas (n=49), and ikan asam pedas (n=25). The results showed a relationship between student preferences for food knowledge, nutritional information, taste, and appearance of traditional West Kalimantan foods. The nutritional composition test showed that, in general, traditional foods have higher water content and lower fat content than ready-to-eat food.

Abstract

Isotonic drinks can replace body fluids quickly because they contain electrolytes needed by the body. This study uses young coconut water as the primary raw material with the addition of pineapple juice to improve the taste and nutritional value of isotonic drinks. This study aimed to determine the characteristics of coconut water isotonic drinks by adding pineapple juice with different formulations and sweeteners. This study used a factorial block randomized experimental design consisting of two factors; the concentration of fruit juice and variations in the type of sweetener. The total of coconut water and pineapple juice was 20 mL with the ratio of coconut water: pineapple juice (14:6); (10:10); and (6:14). The sweeteners used were sucrose (6 g), honey (0.4 g), and stevia (0.03 g). The results showed that the different formulations of coconut-pineapple water affected the antioxidant activity, total dissolved solids, and potassium content of the coconut-pineapple water isotonic drink. Different sweeteners affected the antioxidant activity and total soluble solids of pineapple coconut water isotonic drink. The interaction of formulation and type of sweetener affected antioxidant activity and potassium content. The coconut-pineapple water isotonic drink in this study has met the SNI for isotonic drinks in pH values, sodium content, and total soluble solids for sucrose and stevia sweeteners, but the potassium content still exceeds the standards set by the SNI.
