Abstract

Penelitian ini bertujuan untuk mengetahui hubungan religiusitas dengan kepercayaan diri. Mengingat remaja merupakan tahapan perkembangan yang paling unik, termasuk dalam hal membangun kepercayaan diri. Remaja juga mengalami perkembangan yang unik dalam kehidupan keberagamaannya, sehingga diduga memiliki hubungan dengan kepercayaan dirinya.Responden penelitian ini adalah remaja yang menjadi santri di Madrasah Mu’allimin Muhammadiyah Yogyakarta, yang diambil secara cluster random samping. Data penelitian diambil dengan skala religiusitas dan skala kepercayaan diri, kemudian dianalisis dengan teknik korelasi product moment. Hasil analisis korelasi product moment diperoleh koefisien korelasi (r) = 0,456; danp= ˂ 0,01.Kesimpulan dari hasil penelitian ini bahwa ada hubungan positif yang sangat signifikan antara religiusitas dengan kepercayaan diri.

Abstract

Farmers began to implement organic systems when the quality of rice fields decreased. Indonesia has several active volcanoes so that the agricultural land was formed by generally Entisols. Several natural and synthetic soil conditioners were starting to be used to decompose the litter and increase the availability of Entisol nutrients. The research aimed to study the effect of providing biological soil amendments on the chemical properties of Entisols. The demonstration plots scale research were used a completely randomized design with a combination of treatments: (P1) Flooded dolomite control, (P2) Non-flooded dolomite control, (P3) Flooded bio soil-neutralizer, and (P4) Non-flooded bio soil-neutralizer. Parameters of soil chemical properties observed were pH, C-organic (%), N-total (%), P2O5-total (%), K2O-total (%), CEC (c mol + kg-1), total bacteria (CFU mL-1), and total fungi (spores g-1). The chemical properties of Entisols before treatment showed slightly acidic pH, low C-organic, low N-total, low K-total, low P-total, and very high CEC. After applying the soil neutralizer, there were an increase in chemical properties including pH becoming alkaline and neutral, medium C-organic, standards to moderat NPK-total, and high CEC. Flooding treatment did not increase the chemical properties of the Entisols.

Abstract

Dysmicoccus neobrevipes dari famili Pseudococcidae merupakan hama penting dengan distribusi luas di Indonesia. Serangan hama kutu putih secara ekonomi dapat merusak komoditas pisang asal Maluku Utara. Keberadaan kutu putih di pertanaman sangat beragam dan melimpah. Kutu putih dapat menimbulkan gejala kerusakan pada seluruh bagian tanaman terutama pada buah. Tujuan penelitian adalah mempelajari karakteristik morfologi D. neobrevipes dengan kutu putih jenis lain pada komoditas pisang. Sampel spesimen diambil secara purposive sampling di lima pasar sentra pisang meliputi pasar Bastiong (Pulau Ternate), pasar Jailolo (Halmahera Barat), pasar Tobelo (Halmahera Utara), pasar Labuha (Pulau Bacan), dan Pasar Sanana (Kepulauan Sula). Preparasi spesimen dan identifikasi menggunakan metode Heinz yang dimodifikasi. Variabel pengamatan morfologi berupa bentuk tubuh dan keberadaan organ spesifik kutu putih. Hasil menunjukkan D. neobrevipes berbentuk oval, mempunyai 17 cerarri, sepasang antena, 2–3 discoidal pore, anterior ostiole dan posterior ostiole berkembang baik, 2–4 conical seta, 3–7 auxilary seta, sekelompok trilocular pore, circulus berkembang sempurna, terdapat translucent pore pada tibia dan femur tungkai belakang, oral coral tubular duct bertipe besar dan kecil, dorsal seta lebih pendek dari anal ring seta, multicolar pore terdapat di tengah, anal ring terdiri 6 seta dan anal cerarri terdiri 2 conical seta.

Abstract

Sexava coriacea is the most important pests on coconut in North Maluku. The insects known as coconut treehoppers cause damage to foliar defoliation. S. coriacea attacked coconut crops in Sula-Mangoli Islands first reported by C Willemse in 1930. The reports of the pest monitoring program over the last ten years showed symptoms of moderate attack levels on the leaves which could be controlled. In 2022, there were another pests outbreaks in Halmahera and Sula Islands that inflicted serious leaflets damage on coconut. The research aimed to study the development and distribution of S. coriacea on coconut plantations in the Maluku Islands. The study was used a purposive sampling method in the planting area which showed symptoms of an attack and the presence of the pest target. The pest specimens obtained were identified by morphological characteristics. Leaf damage level obtained was further developed with five categories; healthy, mild, moderate, severe, and very severe. The results showed S. coriacea found in Galela, Sahu, Bacan, and Sanana. Damage rates of coconut crops were calculated in North Halmahera reached 76-100%; West Halmahera reached 26-50%; South Halmahera reached 1-25%; and Sula Islands reached 51-75%.

Abstract

The utilization of wildlife animals and exotic plants in Indonesia is carried out by species diversity and ecosystem balance in their natural habitat. Nowadays, a lot of plant and animal tradings cause the population descending and animals extinction in wildlife. Natural protection and preservation was aimed to maintaining the uniqueness of wildlife animals and exotic plants which are regulated by nature reserve and distributed by quarantine measures at the entry and exit points in seaports and airports. The research was aimed to study the species and protection status of animals and exotic plants in Lifmatola-Waisakai Nature Reserve, Sula Islands, North Maluku. The research design was descriptive-explorative method using Trend Model Time Series that calculated by Acceptance of Plant and Animal Reports. The study showed that 74 birds, 52 rumps of exotic orchids, 15 woods of Meranti, 9 lizards and 2 Timor deer were found during a period of three years of quarantine measures. The majority of wildlife animals and exotic plants with conservation status are protected by law. There were 6 species that had been circulated between the islands i.e Grammatophyllum scriptum, Cymbidium sp., Cacatua alba, Lorius garrulous, Cervus timorensis and Varanus indicus.

Abstract

ABSTRACT Chrysomphalus aonidum is an important pest in fruits. Maluku Utara is a free area of ​​C. aonidum so that any entry of fruit from outside the area must be accompanied by a phytosanitary certificate from the area of ​​origin. Local fruit products have a potential to develop as export commodities, given their large numbers and variety. Problems arised when the larger volumes of fruits imports without going through quarantine measured on fruit products contaminated with pests and diseases can attack Indonesian local fruit commodities. The research was aimed to study the contribution of local fruit production to national production and its potential as an alternative host of C. aonidum. The study was used Trend Model Time Series and Location Quotient (LQ) analysis to discuss the changes of agricultural commodity. The results showed that bananas, melons and oranges have the potential to be the main hosts of C. aonidum while the nutmeg and cacao commodities are alternative hosts. Concentrated local fruit cultivation in a particular area has a greater impact on handling if attacked by C.aonidum than scattered cultivation.

Flooding treatment did not increase the chemical properties of the Entisols.
