Abstract

Sweet potato is a source of carbohydrates, widely cultivated by the people of Papua. Sweet potato have a variety of different types and characters. This diversity has an important in the process of selecting and assembling new superior varieties. Identification based on morphological characters on leaves and tubers can be used to the similarities and differences in plants, both quantitatively and qualitatively. The sugar level in sweet potato tubers needs to be known, because it is related to use as food for patient with degenerative diseases. The aim of the study was to identify the morphological characters of leaves and tubers, as well as sugar level in three sweet potato accessions cultivated by the local community. Identification of morphological characters of leaves and tubers used descriptive methods, while identification of sugar level used experimental methods. The results showed that (1) the morphological characters of the leaves and tubers of the three types of sweet potato cultivated by the local community were different, both quantitatively and qualitatively. (2) The highest sugar level is found in boiled and baked light yellow sweet potatoes. The lowest sugar level was found in boiled white sweet potatoes (3.570brix) and creamy sweet potatoes that were baked (3.130brix). White and creamy sweet potatoes are more suitable for people with degenerative diseases.

Abstract

Banyak jenis hama yang menyerang pohon kakao. Hama utama tanaman kakao di Indonesia adalah penggerek buah kakao (Conopomorpha cramerella) dan kumbang penghisap buah (Helopeltis antonii). Serangan ulat buah kakao (PBK) dapat menurunkan hasil panen biji kakao hingga 82%, sedangkan serangan Helopeltis spp dalam satu musim dapat menurunkan hasil rata-rata sebesar 42% dan pada tahun berikutnya dapat mencapai 61 hingga 75%. Tingginya tingkat serangan hama salah satu penyebabnya adalah berkurangnya ketahanan alami pohon kakao akibat kurangnya unsur hara yang terserap. Helopeltis spp. (Hemiptera: Miridae) merupakan salah satu hama utama tanaman kakao. Serangga ini menyebabkan kerusakan dengan cara melukai dan menghisap sari buah kakao dan tunas muda. Serangan pada buah muda menyebabkan kematian buah dan pada buah setengah tua dapat menyebabkan pembentukan buah tidak normal. Menyusul serangan Helopeltis spp yang seringkali berdampak langsung pada kuantitas atau kualitas biji kakao. Tujuan dari pada penelitian ini adalah untuk mengetahui intensitas kerusakan tanaman kakao di Kampung Sereh dan Yahim Distrik Sentani akibat serangan hama penghisap buah kakao. Penelitian ini dilaksanakan di Kampung Sereh dan Yahim Distrik Sentani Kabupaten Jayapura pada bulan Oktober 2023. Metode yang digunakan dalam penelitian ini adalah survey bebas (free survey) dengan dimana pengumpulan data dilakukan dengan metode pengamatan langsung atau observasi. Intensitas kerusakan buah kakao akibat serangan hama penghisap buah kakao (Helopeltis spp) di Kampung Sereh dan Kampung Yahim Distrik Sentani berkisar antara 36,83 – 38,68 % dengan rata-rata intensitas kerusakan 37,76 % termasuk dalam kategori serangan sedang.

Abstract

Green mustard is one of the vegetables that has commercial value and good prospects. The demand for mustard greens is increasing along with the increase in population and awareness of nutritional value. To meet the demand for mustard greens, it is necessary to increase the volume of mustard greens production, one way is to fertilize well and correctly so as to get maximum results. This study aims to determine the effect of goat manure fertilizer and NPK on the yield of green mustard plants. Based on the results of the study, it was found that; (1) Fertilizing goat dung had no significant effect on the growth and production of mustard greens. NPK fertilization has a real effect on the variables of plant height and fresh weight of plants. (2) NPK fertilization dose of 150 kg/ha produces the highest plant height and fresh weight. The resulting plant height was 50.83 cm and the resulting fresh weight was 259.73 g/plant.

Abstract

Penelitian ini bertujuan untuk mengetahui karakter agronomi 10 aksesi ubi kayu lokal asal Papua. dan dilaksanakan di Kampung Yammua Arso 6 Kecamatan Arso Barat, Kabupaten Kerom, Provinsi Papua selama ±9 bulan, yaitu pada bulan November 2023 sampai dengan Juli 2024. Penelitian ini menggunakan metode eksperimen menggunakan Rancangan acak kelompok (RAK). Variable penelitian terdiri atas tinggi tanaman, diameter batang, panjang umbi, diameter umbi, jumlah umbi per tanaman, bobot umbi per tanaman, jumlah umbi komersil, bobot umbi komersil, jumah umbi per petak, bobot umbi per petak dan indeks panen. Hasil penelitian menunjukkan terdapat perbedaan sangat nyata dan nyata. Terdapat 2 Aksesi Arso 6.1 (A61) dan Arso 6.2 (A62) yang memiliki daya hasil tinggi.

Abstract

Sago dregs are waste from processing sago plants, which can pollute the environment if not utilized. One way of utilizing it is as compost and planting media by using the fungal decomposer Trichoderma. This study aims to determine the effect of Trichoderma on the time of sago pulp composting. The experiment was designed according to a group randomized design, consisting of one treatment factor and five replicates. The results showed that; (1) The addition of Trichoderma affects the decomposition of sago pulp, (2) Trichoderma can accelerate the decomposition time with one parameter, namely temperature. The decrease in decomposition temperature occurred in the third week period, (3) The percentage of material shrinkage and dry weight of sago bagasse material given Trichoderma was significantly different from the control. The highest percentage of shrinkage was in sago bagasse added with 6 grams of Trichoderma.
