Abstract

The fluctuating production of cassava plants both nationally and regionally, especially in the province of Papua and Jayapura district, is suspected to be due to the presence of weeds in the cassava plantation area. The presence of weeds in cassava plantations can inhibit growth and even reduce cassava production by 75% if the weeds are not controlled, especially at the beginning of their growth. The type, nature and population of weeds in the cassava plant area will affect the small amount of losses incurred. The presence of these weeds and their impact on cassava plants can be analyzed from the density level, dominance index and species diversity. The purpose of this study was to determine the types of weeds in cassava plantations and the level of density and dominance of each of these weeds. This research was conducted in Dobonsolo Village, Sentani District, Jayapura Regency, from November 2020 to December 2020. The method used in this study was a free survey with the vegetation analysis method using the quadratic method, namely the analysis method by taking data from each plot. example of a quadrant with an area that is calculated in quadrant units (m²). The quadrant used in this study is a square with a size of 2 m x 2 m. The results of observations of weed types found in cassava gardens in Dobonsolo Village, Sentani District, found 15 types of weeds consisting of 9 families, namely Piperaceae, Commelinaceae, Dennstaedtiaceae, Lamiaceae, Euphorbiaceae, Poaceae, Onagraceae, Rubiaceae, and Fabaceae. The dominant type of weed in cassava gardens in Dobonsolo Village, Sentani District, is Peperomia pellucida L from the Piperaceae family with a NJD value of 12.6%.

Abstract

Sweet potatoes (Ipomoea batatas), better known by the Papuan people as petatas, are a commodity that is widely consumed by the people as a source of carbohydrates to replace rice besides sago, especially in mountainous areas. There are many types of sweet potatoes in the Papua region, some of which are white, yellow, purple and some even have batik-like colors. Sweet potatoes are often used in stone burning activities, traditional ceremonies as well as for people's daily consumption. Insect pests are animals that damage crops and can cause losses for farmers because they can reduce crop production levels and the level of income, farmers will always pay attention and manage it well so that it is always at the economic threshold so that they can increase the production of agricultural products because when these pests are not managed well then the yield will decrease. Information and knowledge about the types of insect pests that attack plants sweet potatoes in a place or field of sweet potatoes play an important role in determining the control measures that will be carried out so that the control can be effective in controlling insect pests and increasing the production of cultivated plants. This research aims to inventory the types of insect pests that attack sweet potato plants (Ipomoea batatas L) in the Waibu district, Jayapura Regency. This research was carried out in farmers' sweet potato plantations in Doyo Baru Village, Waibu District, Jayapura Regency in September - October 2022, observation or data collection was carried out using the observation or direct observation method. Pest insects are obtained by catching them directly or using insect nets. Insect pests that attack sweet potato plants in the Waibu District, Jayapura Regency are turtle beetles (Aspidomorpha miliaris), leaf rollers (Brachmia convolvuli), armyworms (Spodoptera litura), whitefly (Bemisia tabaci), green grasshopper (Atractomorpha crenulata) and sweet potato beetle (Cylas formicarius).

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.
